::Tbe take-up Gore rotates abou~ the take-up hub in an advancing direction. P~th means define a path for the 30 backing strip from the supply roll hub to the take up hub.
The dispenser includes application means compris~fng an application member including an application surface. The application surface forms a 35 length of the path for the backing~trip, and is adapt~d to enqage the release material or seco~d surface of the backing strip.
An actuation member is mounted for manually actua~ed reciprocal movement relative to the housing WO93/04g69 PCT/US92/06669 2 i ~ 0 between a projecting position with a distal surface projecting past the open end of the housing to afford positioning the application surface opposite a substrate and a retracted position with the application 5 surface and the distal surface of the actuation member generally aligned so that the predetermined length of transfer adhesive on the backing strip may be pressed into contact with the substrate positioned opposite the application surface.
Advancing means are coupled between the actuation member and the take-up assembly for advancing ~he predet~rmined length of the backing strip and the transfer adhesive along the path to position the predetermined length of adhesive strip along the 15 application surface.
In operation, upon movement of the actuation m~mber from the projecting position to the retracted position, the advancing means advances the predetermined length of the backing strip and the 20 transfer adh~sive along the p,ath to position the predetermined length of adhesive strip along t~e app~ication surface. ~he application surface may be manually pressed against the substrate by manual pressure on the housing. When the application surface 25 is manually pressed against the substrate, the transfer adhesive is pressed against the substrate and adheres to the substrate. Upon movement of the actuation member from the retracted position to the projecting positi~n 9 the transfer adhesive that was pressed

Preferably, the path means comprises a guide member having a land surface projecting from the base wall. Also preferably the dispenser includes biasing 35 means such as a coil or a torsion spring for biasing the actuation member toward the projecting position.
In a first embodiment o~ dispenser according to the pre ent inYention, the advancing assembly compri~es an elongate drive member having a first end W093/04969 2 i 1 ~ 1 o PCT/US92/06669 attached to the actuation means and a second engagement end. The take-up core is generally cylindrically-shaped and has a plur~lity of generally radially projecting drive ribs~ Means mount the 5 elongate drive member on the housing to reciprocably move from ~1) a release position with the second engayement end spaced from the radially projecting drive ribs to (2) an engage position between which release nd engaqe positions the second engagement end 10 is adapted to engage one of the drive ribs and rotate the take-up core to advance the length of the backing strip and the transfer adhesive a predetermined length ~alon~ the path, Wh~n the actuation member is~moved ~rom the proiecting position to the retracted position, 15 the elongate drive member moves from the release to the engage position.
Guide means are mounted Qn the housing for guiding the engagement end of the drive member into ~ngagement with a drive rib upon movement from the 20 release to the engage position and for preventing engagement between the engagement end and the radially projecting drive ribs when the elongate drive member moves from the engage position toward the release position.
The first embodiment of dispenser according to the present invention also includes arresting means comprising the take-up core having a ratchet having specially shaped ratchet teeth attached thereto, the housing having an integral pawl. The pawl has an 30: engagement en~ for engaging the specially shaped ratchet te~th ~or arresting rotation of the take-up core in a direction other than the advancing direction and for.~a~fording intermittent moveme~t of the take-up core in the advancing direction. The arrest.ing~means ~35 restricts backlash of the backing strip.
~ n a second embodiment of dispenser according to the present inYention the advancing means compri~es an alongate drive member having a ~irst end attached to the actuation means and a second engagement W093/04~69 PCT/US92/06669 211~ ~ 40 end, and the dispenser housing includes arcuate gear bearing surfaces.

Detailed Description Referring now to ~igures 1 through 8 of the drawing, there i5 shown a first embodimen~ of a hand W~9~/04969 21 1 r~ i ~ O PCT/US92/0666g g held definite length transfer adhesive dispenser arcording to the pxesent invention generally designated by the reference number 10. The dispenser 10 is adapted to apply a "spot" or predetermined length sf a 5 transfer adhe~ive 12 to a substrate (not shown) from a supply roll 14 of the transfer adhesive 12 comprising a supply core 15 having a through opening defined by a cylindrical inner surface 16 having an inner diameter of approximately 2.62 c~ntimeters (1.030 inches), and a 10 length of backing strip 17 wound around the ~upply core 15O The backing strip 17 has first 18 and second 19 major surfaces with the transfer adhe~ive releasably attached to the first major surface 18 and with the -surfa es 18 and 19 coated with a release me~ns or 15 material prepared by methods known in the art. For example~ the release material on surfaces 18 and 19 may comprise a low adhesion backsize~ -The transfer adhesive 12 may comprise any suitable transfer adhesive that will cleanly break or 20 fracture and separate from the backing 17. "Cleanly breaking~' is defined herein as a separation of a portion of the adhesive 12 (the predetermined length) from the backing 17 and the remaining portion of the adhesive without excessive extraneous fibers or strings 25 of adhesive trailing from the edges of the transferred adhe~ive. For example the tran~fer adhesive may comprise a pressure sensitive adhesive comprising infusible, solvent dispersible, solvent-insoluble, inherently tacky, elastomeric oopolymer microspheres 30 which consist essentially of about 90 percent to about 99.5 percent by weight of at least one alkyl acrylate ester and about 10 to about 0~5 percent by weight of at least one.~onomer selected from the group consistin~ of substantially oil-insoluble, water soluble i.onic 35 monomers and maleic anhydride.
The opolymer microspheres are small in size, and have diame ers in the range of about 1 t~
a~out 250 microns. The diameter of a majority of the spheres fall in the range of about 5 to about 150 :
W09~/0496~) PCT/US92/06669 ~1154~ o-microns. Polymeric microsphere adhesives are disclosed for example, in U.S. Patent number 3,6gl,140.
Although the above microspheres are preferred, it is also contemplated that hollow micro~phere adhesives may 5 be used that are repositionable pressure-sensitive adhesives comprising from about 70 percent to about 99 percent hollow, polymeric, acrylate, inherently tacky, infusible, solvent insoluble, solvent-dispersible, elastomeric microspheres comprising at least one alkyl lO acrylate or alkyl methacrylate ester, a majority of the microspheres having one or more in~erior ~oids having a diameter c)~ a least about 10 percenk of the diameter of the microsphere, and correspondin~ly, from about 1 percent to about 30 percent of binder, copolymer 15 comprising an elastomeric polymeric backbone having pendant high Tg polymeric moieties. These hollow microspheres are normally tacky, elastomeric, insoluble but are swellable in organic solvents. The microspheres typically have di.ameters of at least about 20 1 micron, and preferably diameters in the range of about 1 to about^:250 microns. The voids typi ally range in size up to about lO0 microns or larger. -~
Hollow polymeric microsphere adhesives are disclosed, for example in U.S. Patent number 4,994,322.
25- The above mentioned microsphere adhesives ha~e been found to provide an effective transfer adhesive when used alone or with a film forming acrylate adhesive such as an adhesive having 95 par~s of isooctyl acrylate and 5 parts acrylic acid. When 30 the microsphere adhesive is used in combination with a film forming adhesive, a range of from about 1 to about 30 parts of film forming adhesive may be used.
Prefera~ly a blend of microsphere adhesive to acrylic adhesive is 90 parts microsphere adhesive to about 10 35 parts acrylic or film forming adhesive~ When coated onto the release side l9 of the ba~king 17 or liner, a preferred coating weight of 25 grams of coating per -~uare meter was found to be easily transferred while maintaining a sufficient amount of adhesion to properly WO 9~/04~69 2 ~ 1 5 4 ~i O Pcr/us92/o6669 adhere a photograph to a paper substrate. The adhesive blend may be coa~d onto a silicone liner or backing such a~; the liner designated as 2~60BKG-157-99~M, available from the Daubert Company of 5 Oak Brook, Illinois. The blend has been found to be particularly useful for mounting p~otographs.
Although the above adhesive blends were preferred, addition~l adhe~ives may be utilized such as tackified rubber-ba~ed resins available as the KRATON
10 rubbers from the Shell Chemical Company of Oak Brook, Illinois, and film ~orming alkyl acrylate copolymers such as those described in U.S. Patent number-~3,857,731p the entire c~ntent~ of which are also herein expressly incorporated by reference.~ When these 15 adhesives are utilized, additional materials should be added to render the adhesive frangible.
A frangible adhesive is defined as an adhesive which is readily or easily broken ~part or fractured from:its matrix or render the adhesive 20 frangible. In the case of the microsphere/acrylate blends, the microspheres act as a frangible agent to ~-render the adhesive frangible.~ When the adhesive is free of microsph~res; ceramic, glass or polymeric spheres, bubbles or ~ibers may alternatively be used to 25 impart the frangible characteristic or nature to the adhesiveO Alternatively, when a non frangible adhesive (e.g. an adhesive which does not readily separate from itself) is used, pattern coating techniques may be used to coat the non-frangible adhesive onto a liner 50 that 30 a definite length of the adhesive transfers to the substrate.
The dispenser 10 comprises a housing 20 having ~ ousing axis A (Figure 4), a base wall 21, side walls 22, and surfaces defining an open end 26.
35 Th~ housing 20 may comprise a polygonal structu~e ha~ng a width of 6.35 centimeters (2.500 inches), a height of approximately 15.24 centimeters (6~09 inche~
and a thickness of approximately 3.18 centimeters (1.250 inçhes). The housing may be constructed from W093/04g~ PCT/US92/0~669 ~15~-lO - 12 -any suitable material such as a metal or plastic including but not limited to polyester, ABS plastic, polystyrene or polypropylene.
Preferably the housing 20 is formed in two 5 pieces including a base portion B and a cover portion C. The base portion B and cover portion C have cooperable grooves and flanges which af~ord a removable press-~it attac ~ ent of the base R to the cover C
portion. Removal of the c~ver portion C affords access 10 to th~ inner surfaces of the housing 20 so that a user may replace a depleted supply roll 14 with a replacement supply roll.. -The housing 20 has an out~r surface adaptedto be manually grasped (~igure 1), a supply roll hub 23 15 having an arcuate periphery and axia7ly spaced ends with one of the ends being fixed ~o the base wall 21.
The inner surface ~6 of ~he supply core 15 is journaled on the periphery of the supply roll hub 23, and th~
dispenser 10 includes a merhanism for restricting free 20 rotation of the ~upply ~oll 1~4 about the supply roll hub 23 compri ing the supply roll hub 23 bei~g a generally flexible arc~ate member that is radially mo~able between (1) a relaxed position where the supply roll hub 23 has a diameter genera~ly slightly greater 25 than the diameter of the inner surface 16 of the supply core 15, and (2) a loaded position (Figure 2) with the supply cor~ 15 journaled on the supply roll hub 23 with the peripheral surface of the supply roll hub 23 in frictional engagement with the inner surface of the 30 supply core 15 to restrict free rotation of the supply c~re 15. The stiffness of the supply roll hub 23 biases the peripheral surface of the supply roll hub 23 into fric~ional engagemant with the inner ~urface of the supply core 15 when the supply roll hub 23 is in 35 the loaded position. Preferably, a friction projection .
24 may be present to fictionally engage the inner surf ace of the supply core 15 to restrict free rotation of the supply roll 14~
W093/(~49fi~ 5 4 ~ o PCT/us92/06669 The dispenser lO also comprises a take-up means or assembly 30 including the housing 20 having a take-up hub 31 having an arcuate periphery, and axially spaced ends with one of the ends being fixed to the 5 base wall 21. The take-up assembly 30 includes a take-up core 32 having cylindrical inner surfaces having an inner diameter of approximatel~ 3.81 centimeters (1.500 inches). Tha take-up core 32 is journaled on the periphery of the taka-up hub 31 and 10 has a portion of the backing strip 17 wound thereon after application of the adhesive 1~ to the substrate.
The take-up core 32 rotates about the`
take~up hub 31 in an advancing directiQn. Path mean~
15 define a path for the backing strip 17 from the supply roll hub 23 to the take-up hub 31. Preferably, the path means comprises a guide member 36 having a land surface 37 projecting from the base wall 21 with a ~irst end fixed to the base wall and a second end 20 remote from t~e base wall 21.
Application means are present and comprise an application member 40 including an application surface 41 (e.g. a rectangular surface having a width of 1.91 centimeters or 0.75 inches) having a ~irst end 25 fixed to the ba~e wall 21 and a second end remote from the base wall 21.. The application surface 41 forms a length of the path for the backing strip 17, and is ad~pted to engage the releas~ material or low adhesi~n backsize surface 19 of the ba~king strip 17.
An actuation member 44 is mounted for manually actuated reciprocal movement relative to the housing 20 between a projecting position (Figure 4) with a ~,~tal surface 46 projecting past the open end 26 of the housing 20 to afford positioning t.~e 35 application surface 41 opposite a substrate and a L retracted position (Figure 6) with the application surface 41 and the distal surface 46 of the actuation member 44 generally aligned so that the predetermined length o~ transfer adhesi~e 12 on the backing.strip 17 W093/~4969 . PCT/US92/06669 2 1 1 S 4 i0 - 14 - ~
may be pressed into contact with tha substrate positioned opposite the application surface 41. The actuation member 44 is preferably constructed from a transparent polymeric ma~erial. A user may see the 5 substrata through this portion of the dispenser 10 to afford ~asy, convenient positioning the application surface 41 opposite a substrate. Optionally, visual indicia such a~ arrows may be printed on the actuation member to further assist in locating the adhesi~e 10 '~spotl' on the substrate.
The dispenser 10 also includes advancing means ~8 coupled between the actuation member 44 and the take-up assembly 30 for advancing the predetermined length of the backing strip 17 and the transfer 15 adhe ive 12 along the path to position the predetermined length of adhesive strip 17 along the application surface 41.
In the first embodiment of dispenser according to the present invention, th~ advancing means 20 or assembly 48 comprises a flexible elongate drive member 50 having a first end 51 attached to the actuation member 44 and a T-shaped second engagement end 5~. The take-up core 32 is generally cylindrically-shaped and has a plurality of generally 25 radially projecting drive ribs 54 adapted ~o engage the end 52 of the drive member~
Means such as a sleeve portion 25 of housing 20, mount the elongate drive member 50 on the housing to raciprocably move relative to the housing 20 between (l) a release position (Figure 43 with the second engagement end 52 spaced from the radially projecting drive ribs 54 and (2) an engage position between which release..a~d engage positions the second engagement end 52 is adapted to engage one of the drive ribs 54 (Figure 5) and rotate the take up core 32 t~ advance the length of the backing strip 17 and the transfer adhesive 12 a predetermined length along the path. A
detent surface on sleeve portion 25 fits into a groove WO ~3/(~4969 2 1 1 ~ ~ ~ o Pcr/us92/o6~69 surface on the drive member 50 to limit the m~vement of the drive member 50 relative to the housing 20.
Also preferably the dispenser 10 includes biasing means such as a coil spring 43 for biasing the 5 actuation member 44 toward the projecting position. As 3~e~;t seen in Figure ~, one enà of the-spring ~3 contact~; the sleeve portion 25 and the other end of the ~pring contacts the actuation member 44..
Figures 4 through 6 sequentially illustrate 10 movement of the take-up assembly 30 and drive member 50 of the dispenser 10. When the a;::tuation member 44 is moved from the projecting position toward the retracted position, the elongate drive mem~er 50 moves- from the release toward the engage position. A guide means such 15 as an engagement shoulder S6 is mounted on the housing 20 and comprises f irst 61 and second 62 portions . The f irst portion 61 of the shoulder 56 engages a portion of the T-shaped end 52 and cams the T-shaped end 52 of the drive mem}: ~r SO toward thle drive ribs 54 and guides 20 the end 52 into engagement with a drive rib 54 (Figure 5). As the T-shaped end 52 is engaged with a rib 54 and moves along the f irst and second portions 61 and 62, the take up core 3 2 rotate~; and advanc:es the backing 17 the predetermined length. When the f irst 25 portion 61 of the shouIder 56 :carns the end 52 of the drive member 50 toward the drive ribs 54, the stiffness of the driv~ member 50 biases the end ~2 away from the .:
drive rib 54. Once the T-shaped end 52 of the ~rive member 50 passes the second portion 62, the stif ~ness 30 of the member 50 causes the T-shaped end 52 to "spring"
to ~he side of the shoulder 56 w~ h is opposite: the side facing ribs 54. After the T-shap~d end 52 passes the secan~i portion 62 of the shoulder 56, the shoulder - 56 prevents engagement between the end 52 and the 35 radially projecting drive ribs 54: when spring 43 causes the elongate drive member 50 to move~ back~ to the release position.
Optionally, the f irs~ embodiment of dispenser according to the present invention includes W093/~)4969 PCr/US92/06669 arresting means comprising the take-up core 32 having a ratchet 58 having specially shaped ratchet teeth 59 attached there~o. The housing 20 has a pawl 57 attached thereto. The pawl 57 has an engagement end for 5 engaging the ~pecially shaped ratchet teeth 59 for arresting rotation of the take~up core 32 in a direction other than the advancing direction and for affording intermittent movement of the take-up core 32 in the advancing direction. The arresting means 10 restricts backlash of the backing strip 17.
Referring now to Figures 9 through 14 of the drawing, there is shown a~second alternativ~ embodiment of dispenser. according to the present invention generally designated by the reference.number 100 Which 15 has many parts that are essentially the same as the parts of the dispenser 10. The dispenser 100 is smaller th~n the dispenser 10, is more readily manipulated by a user and requires less storage space.

An ac~uation member 144 is mounted for 10 manually actuat~d reciproc:al movement relative to the housing 120 between a projecting position (Figures ~
and 11~ with a distal surface 146 projecting pa8t the open end 126 of the housing 120 to a~ford positioning the application surface 141 opposite a substrate and a 15 retracted position (Figure 13 )~ with the application surf ace 141 and the distal surf ace 14 ~ of the actuation member 144 generally aligned ~;Q that the predetermined length of transfer adhesive 12 on the ba~king s~rip 17 may be pressed into contact with th~ substrate 20 ps)sitioned opposits the application~ surface 14I. The actuatiorl mem}:~er 144 is preferably constructed from a material similar to th~ material used to construc:t the member 44 and may include similar indicia.:
The dispenser 100 has a different take-up 25 assembly 130 ~ban the dispensex 10. The take-up assembly 130 c::omprises the housing 120 having a take-up .
hub 131, and arcuate gear bearing surfaces 149 (e.~..
cylindrical surfa::es with the radially outer~ surfaces having an inner diameter of approximately 3 . 39 30 centimeters, 1. 330 inches and with the radially inner surfaces having an outer diameter of apprc~ximately 1. 69 centimeters, O. 666 inches) .
The take-up assembly 13 0 includes a take-up c:ore 13~ and,~ the dispenser 100 includes an eccentric 35 orbital gear system comprising a drive gear I02. The d~ive gear 102 is journaled on the arcuate gear bearing surfaces 149 and has a plurality of gerlerally radially outwa;rdly projecting drive ribs 154, and radially inwardly projecting teeth 155. The take-up assembly W093/~4969 ~ll5~ln PCI`/US92/06669 130 includes a driven pinion gear 106 having an outer diameter of about 1.27 c~ntimeters, 0.5 inches. The :~
driven pinion gear 106 is attached to a take-up core -~
132 and has an axis offset from the axis of the gear 5 bearing surfaces 14g. The driven pinion gear 106 includes radially outwardly projecting teeth lOi adapted to engage the teeth 155 of the drive gear 102 to provi~e a gear ratio of approximately 2:1.
The take-up core 132 has arcuate inner 10 surfaces and those inner surfaces are journaled on the peripheral surfaces of the take-up hub 131 ~Figure 11).
Both the take-up core 132 and:the drive gear 102 rotate about axis and those axis are spaced from one another.
.
~ike the advancing means 48, the advancing means 148 is coupled between the actuation member 144 and the take-up assembly 130 for advancing the predetermined length of he backing strip 17 and the transfer adhesive 12 along the path t~ posi~ion the 20 predetermined length of adhesive strip 17~along the application ~urface 41. Also9 the advancing means 48 comprises a flexible elongate drive member I50 having a first end 151 attached to the actuation member 144 and a T-shaped secon~ engagement end 152. ~
Unlike the dispenser 10, the dispenser lO0 includes means mounting a drive member 150 on the :housing to reciprocably move from (1) a release position with the second engagement end 152 spaced from ~:
the~radially projecting drive ribs 154 to (2) an engage 30 position between which release and engage position~ the second engagement end 152 is adapted to engage one of the ribs 154 o~ the drive gear 102 which rotates the driven ~linion gear 106 which in turn rotates the take-up core 132 to advance the length of the backing 35 strip 17 and the tran~fer adhesive 12 a predet~rmined length along the path.
The dispenser lO0 includes means such as a sleeve portion 125 of housing 120, which mounts the elongate drive member 150 on the housing 120 to ~9~/049fi9 PCTtUS92/0~669 i0 20 reciprocably move relative to the housing 120 from (1) a release position with ~he second engagement end 152 spaced from the radially outward projecting drive ribs ~54 to (2) an engage position between which release and 5 engage positions the ~ecnnd engagement end 152 is adapted to engage one of the drive ribs 154 (Figure 12) and rotate gear 102 which rotates gear 106 and take-up core 132 to advance the leng~h of the backing strip 17 and the transfer adhesive ~2 a predetermined length lO along th~ path. A detent surfare on sleeve portion 125 fits into a groove surface on the drive member 150 to limit the mo~ement of the drive member 150 relative to the housing 120.~
Also preferably the dispenser lO includes 15 biasing means such as a torsion spring 143 for biasing the actuation member 144 toward the projecting position, As best seen in Figure 12, on~ end of the spring 143 is mounted on a shoulder in driv~ member 150 and the other end of the spring 143 is mounted to the 20 housing 120.
Figures 11 through 13 sequentially illustrate movement of the take-up assembly 130 and drive member 150 of the dispenser 100. When the actuation member 144 is moved from the projecting 25 position toward the retracted positi~n, the elongate dri~e member 150 ~oves from the release toward the~
engage position. A guide means such as an engagement shoulder is moun~ed on the housing 120 and comprises first 161 and second 162 portions. The first portion 30 161 of th~ shoulder engages a portion of the T-shaped end 152 and cams the T-shaped end 152 of the drive member 150 toward the drive ribs 154 and guides the end !
152 int~ engagement with a drive rib 154 (Figure 12).
As the T-shaped end 152 is engaged with a rib 154 and 35 moves along the first and second portions 161 and 162, the gear 102 rotate which in turn rota~es gear 106 and take-up core 132. Rotation of take-up core 132 advances the backing 17 the predetermined lengthO
W~3/~4969 2 1 1 5 ~ ~ O PCT/US92/0~669 When the first portion 161 of the shoulder 156 cams the end 152 of the drive member 150 toward the drive ribs 154~ the stiffness of the drive member 150 biases the end 152 away from the drive rib 154. Once 5 the T-shaped end 152 of the drive member 150 passes the second portion 162, the stiffness of th member 150 caus~s the T-shaped end 152 to "spring" to the side of the shoulder 156 which is opposite the side facin~ ribs :~
154. After the T-shaped end 152 passes the ~econd 10 portion 162 of the shoulder 156, the shoulder 156 acts as a barrier to prevent engagement between the end lS2 a~d th~- radially projecting drive ribs 15~ when spring :-143 causes the elongate drive member 150 to move:back to the release position.
Optional~y, the dispenser 100 may include arresting means to re~trict backlash of the backing strip 17. The arresting means comprises the drive gear 102 having a ratchet 158 havi~g specially shaped ratchet tseth lS9, the housing 120 having a pawl 157 20 with a dist~l engagement end for engaging the specially shaped ratchet~teeth 1S9 for arresting rotation of the drive gear 102 in a direction other than a direction which moves the take-up core 132 in the advancing direction and for a~fording intermittent movement of 25 the take-up core~132 in ~he advancing direction.

:Operation The operation of the dispenser according:to 30 the present invention will now be described with ~reference to th~ first embodiment of dispenser 10.
Initially a user manually grasps the housing 20 and ` sele ts.a~position on a substrate for application of a - '~spoti' or predetermined length of adhesive 12. The 35 user may look:through transparent actuation member 44 : . to precisely position the dispenser 10 adjacent the substrate. The user then simply presses the housing 20 axially downward ~oward the substrate. Such manual WO93/049fi~ PCT/US92/06669 pressing moves the housing 20 relative to the actuation member 44.
Upon movemen of the actuation member 44 from the pro3ecting (Figure 4) toward the retracted 5 position (e.g. by manually pressing the housing 20 downward toward the subs~rate)~ the advancing means 4~
advances the predetermined length of the backing strip 17 and the transfer adhesive 12 along the path to position the predetermined length of adhesive strip 10 along the application surface 41. The downward pressure on the housing 20 causes the application surface 41 to press against the substrate causing the transfer adhesive 1~ to adhere to the subs~rate. Once the downward pressure on the housing 20 is released, 15 the sprin~ 43 biases the actuation member 44 from the retracted position to the projecting position, and the transfer adhesive 12 that was pressed against the substrate tears from the backing strip 17 and adheres to the sub trate.
The present inventi.on has now been described with reference to several embodime~ts thereof. It will be apparent to those skilled in the art tha~ many changes can be made in the embodiment described without departing from the scope of the present invention.
Preferably, the path means comprises a guide member having a land surface projecting from the base wall. Also preferably the dispenser includes biasing 35 means such as a coil or a torsion spring for biasing the actuation member toward the projecting position.
In a first embodiment o~ dispenser according to the pre ent inYention, the advancing assembly compri~es an elongate drive member having a first end W093/04969 2 i 1 ~ 1 o PCT/US92/06669 attached to the actuation means and a second engagement end. The take-up core is generally cylindrically-shaped and has a plur~lity of generally radially projecting drive ribs~ Means mount the 5 elongate drive member on the housing to reciprocably move from ~1) a release position with the second engayement end spaced from the radially projecting drive ribs to (2) an engage position between which release nd engaqe positions the second engagement end 10 is adapted to engage one of the drive ribs and rotate the take-up core to advance the length of the backing strip and the transfer adhesive a predetermined length ~alon~ the path, Wh~n the actuation member is~moved ~rom the proiecting position to the retracted position, 15 the elongate drive member moves from the release to the engage position.
Guide means are mounted Qn the housing for guiding the engagement end of the drive member into ~ngagement with a drive rib upon movement from the 20 release to the engage position and for preventing engagement between the engagement end and the radially projecting drive ribs when the elongate drive member moves from the engage position toward the release position.
The first embodiment of dispenser according to the present invention also includes arresting means comprising the take-up core having a ratchet having specially shaped ratchet teeth attached thereto, the housing having an integral pawl. The pawl has an 30: engagement en~ for engaging the specially shaped ratchet te~th ~or arresting rotation of the take-up core in a direction other than the advancing direction and for.~a~fording intermittent moveme~t of the take-up core in the advancing direction. The arrest.ing~means ~35 restricts backlash of the backing strip.
~ n a second embodiment of dispenser according to the present inYention the advancing means compri~es an alongate drive member having a ~irst end attached to the actuation means and a second engagement W093/04~69 PCT/US92/06669 211~ ~ 40 end, and the dispenser housing includes arcuate gear bearing surfaces. The second embodiment of dispenser includes an eccentric orbital gear system comprising a drive gear journaled on the arcuate gear bearing 5 surfaces and having a plurality of generally radially outwardly projecting drive ribs, and radially inwardly projecting teeth, a driven pinion gear attached to the take-up core and having an axi~ offse~ from the axis of the gear bearing surfaces and radially outwardly 10 projecting teeth adapted to engage the teeth of the drive gear.
In the second embodiment of dispenser . .
according to the present invention, the advancing means comprises means mounting ~he elongate drive member on 15 the housing to reciprocably move from (1) a release position with the second engagement end spaced from the radially pro~e~-ting drive ribs to (2) an engag2 position between which release and engage positions the second engagement end is adapted to engage one of the 20 ribs of the dri~e gear which rotates the driven pinion gear which in turn rotates the take-up core to advance the leng~h of the backing strip and the transfer adhesive a predetermined length along the path. Since the drive member is atta~hed to the actuation member, 25 when the actuation member is moved from the projecting position to the retracted pQSition, the elongate drive member moves from the release to the engage position.
~ ike the first embodiment of dispenser according to the present invention, the second 30 embodiment of dispenser according to the present invention includes guide means similar to the guide mean~ in the Pirst embodiment and arresting means.
~owe~er~.~he arresting means of the second embodiment comprises the driYe gear having a ratchet having 35 specially shaped ratchet teeth, the housing having a pawl with a distal engagemant end for engaging the ~pecially ~haped ratchet t2eth for arresting rotation of the drive gear in a direction other than a direction which moves the supply core in the advancing direction -W093/049~9 2 ~ i 5 4 ~1 o Pcr/US92/06669 and for affording intermitten-t movement of the take up core in the advancing dirsction. Optionally the taXe-up hub may have a friction brake operatively connected thereto to further restrict backlash of the 5 backing.

The dispenser 10 is adapted to apply a "spot" or predetermined length sf a 5 transfer adhe~ive 12 to a substrate (not shown) from a supply roll 14 of the transfer adhesive 12 comprising a supply core 15 having a through opening defined by a cylindrical inner surface 16 having an inner diameter of approximately 2.62 c~ntimeters (1.030 inches), and a 10 length of backing strip 17 wound around the ~upply core 15O The backing strip 17 has first 18 and second 19 major surfaces with the transfer adhe~ive releasably attached to the first major surface 18 and with the -surfa es 18 and 19 coated with a release me~ns or 15 material prepared by methods known in the art. For example~ the release material on surfaces 18 and 19 may comprise a low adhesion backsize~ -The transfer adhesive 12 may comprise any suitable transfer adhesive that will cleanly break or 20 fracture and separate from the backing 17. "Cleanly breaking~' is defined herein as a separation of a portion of the adhesive 12 (the predetermined length) from the backing 17 and the remaining portion of the adhesive without excessive extraneous fibers or strings 25 of adhesive trailing from the edges of the transferred adhe~ive. For example the tran~fer adhesive may comprise a pressure sensitive adhesive comprising infusible, solvent dispersible, solvent-insoluble, inherently tacky, elastomeric oopolymer microspheres 30 which consist essentially of about 90 percent to about 99.5 percent by weight of at least one alkyl acrylate ester and about 10 to about 0~5 percent by weight of at least one.~onomer selected from the group consistin~ of substantially oil-insoluble, water soluble i.onic 35 monomers and maleic anhydride.
The opolymer microspheres are small in size, and have diame ers in the range of about 1 t~
a~out 250 microns. The diameter of a majority of the spheres fall in the range of about 5 to about 150 :
W09~/0496~) PCT/US92/06669 ~1154~ o-microns. Polymeric microsphere adhesives are disclosed for example, in U.S. Patent number 3,6gl,140.
Although the above microspheres are preferred, it is also contemplated that hollow micro~phere adhesives may 5 be used that are repositionable pressure-sensitive adhesives comprising from about 70 percent to about 99 percent hollow, polymeric, acrylate, inherently tacky, infusible, solvent insoluble, solvent-dispersible, elastomeric microspheres comprising at least one alkyl lO acrylate or alkyl methacrylate ester, a majority of the microspheres having one or more in~erior ~oids having a diameter c)~ a least about 10 percenk of the diameter of the microsphere, and correspondin~ly, from about 1 percent to about 30 percent of binder, copolymer 15 comprising an elastomeric polymeric backbone having pendant high Tg polymeric moieties. These hollow microspheres are normally tacky, elastomeric, insoluble but are swellable in organic solvents. The microspheres typically have di.ameters of at least about 20 1 micron, and preferably diameters in the range of about 1 to about^:250 microns. The voids typi ally range in size up to about lO0 microns or larger. -~
Hollow polymeric microsphere adhesives are disclosed, for example in U.S. Patent number 4,994,322.
25- The above mentioned microsphere adhesives ha~e been found to provide an effective transfer adhesive when used alone or with a film forming acrylate adhesive such as an adhesive having 95 par~s of isooctyl acrylate and 5 parts acrylic acid. When 30 the microsphere adhesive is used in combination with a film forming adhesive, a range of from about 1 to about 30 parts of film forming adhesive may be used.
Prefera~ly a blend of microsphere adhesive to acrylic adhesive is 90 parts microsphere adhesive to about 10 35 parts acrylic or film forming adhesive~ When coated onto the release side l9 of the ba~king 17 or liner, a preferred coating weight of 25 grams of coating per -~uare meter was found to be easily transferred while maintaining a sufficient amount of adhesion to properly WO 9~/04~69 2 ~ 1 5 4 ~i O Pcr/us92/o6669 adhere a photograph to a paper substrate. The adhesive blend may be coa~d onto a silicone liner or backing such a~; the liner designated as 2~60BKG-157-99~M, available from the Daubert Company of 5 Oak Brook, Illinois. The blend has been found to be particularly useful for mounting p~otographs.
Although the above adhesive blends were preferred, addition~l adhe~ives may be utilized such as tackified rubber-ba~ed resins available as the KRATON
10 rubbers from the Shell Chemical Company of Oak Brook, Illinois, and film ~orming alkyl acrylate copolymers such as those described in U.S. Patent number-~3,857,731p the entire c~ntent~ of which are also herein expressly incorporated by reference.~ When these 15 adhesives are utilized, additional materials should be added to render the adhesive frangible.
A frangible adhesive is defined as an adhesive which is readily or easily broken ~part or fractured from:its matrix or render the adhesive 20 frangible. In the case of the microsphere/acrylate blends, the microspheres act as a frangible agent to ~-render the adhesive frangible.~ When the adhesive is free of microsph~res; ceramic, glass or polymeric spheres, bubbles or ~ibers may alternatively be used to 25 impart the frangible characteristic or nature to the adhesiveO Alternatively, when a non frangible adhesive (e.g. an adhesive which does not readily separate from itself) is used, pattern coating techniques may be used to coat the non-frangible adhesive onto a liner 50 that 30 a definite length of the adhesive transfers to the substrate.
The dispenser 10 comprises a housing 20 having ~ ousing axis A (Figure 4), a base wall 21, side walls 22, and surfaces defining an open end 26.
35 Th~ housing 20 may comprise a polygonal structu~e ha~ng a width of 6.35 centimeters (2.500 inches), a height of approximately 15.24 centimeters (6~09 inche~
and a thickness of approximately 3.18 centimeters (1.250 inçhes). The housing may be constructed from W093/04g~ PCT/US92/0~669 ~15~-lO - 12 -any suitable material such as a metal or plastic including but not limited to polyester, ABS plastic, polystyrene or polypropylene.
Preferably the housing 20 is formed in two 5 pieces including a base portion B and a cover portion C. The base portion B and cover portion C have cooperable grooves and flanges which af~ord a removable press-~it attac ~ ent of the base R to the cover C
portion. Removal of the c~ver portion C affords access 10 to th~ inner surfaces of the housing 20 so that a user may replace a depleted supply roll 14 with a replacement supply roll.. -The housing 20 has an out~r surface adaptedto be manually grasped (~igure 1), a supply roll hub 23 15 having an arcuate periphery and axia7ly spaced ends with one of the ends being fixed ~o the base wall 21.
The inner surface ~6 of ~he supply core 15 is journaled on the periphery of the supply roll hub 23, and th~
dispenser 10 includes a merhanism for restricting free 20 rotation of the ~upply ~oll 1~4 about the supply roll hub 23 compri ing the supply roll hub 23 bei~g a generally flexible arc~ate member that is radially mo~able between (1) a relaxed position where the supply roll hub 23 has a diameter genera~ly slightly greater 25 than the diameter of the inner surface 16 of the supply core 15, and (2) a loaded position (Figure 2) with the supply cor~ 15 journaled on the supply roll hub 23 with the peripheral surface of the supply roll hub 23 in frictional engagement with the inner surface of the 30 supply core 15 to restrict free rotation of the supply c~re 15. The stiffness of the supply roll hub 23 biases the peripheral surface of the supply roll hub 23 into fric~ional engagemant with the inner ~urface of the supply core 15 when the supply roll hub 23 is in 35 the loaded position. Preferably, a friction projection .
24 may be present to fictionally engage the inner surf ace of the supply core 15 to restrict free rotation of the supply roll 14~
W093/(~49fi~ 5 4 ~ o PCT/us92/06669 The dispenser lO also comprises a take-up means or assembly 30 including the housing 20 having a take-up hub 31 having an arcuate periphery, and axially spaced ends with one of the ends being fixed to the 5 base wall 21. The take-up assembly 30 includes a take-up core 32 having cylindrical inner surfaces having an inner diameter of approximatel~ 3.81 centimeters (1.500 inches). Tha take-up core 32 is journaled on the periphery of the taka-up hub 31 and 10 has a portion of the backing strip 17 wound thereon after application of the adhesive 1~ to the substrate.
The take-up core 32 rotates about the`
take~up hub 31 in an advancing directiQn. Path mean~
15 define a path for the backing strip 17 from the supply roll hub 23 to the take-up hub 31. Preferably, the path means comprises a guide member 36 having a land surface 37 projecting from the base wall 21 with a ~irst end fixed to the base wall and a second end 20 remote from t~e base wall 21.
Application means are present and comprise an application member 40 including an application surface 41 (e.g. a rectangular surface having a width of 1.91 centimeters or 0.75 inches) having a ~irst end 25 fixed to the ba~e wall 21 and a second end remote from the base wall 21.. The application surface 41 forms a length of the path for the backing strip 17, and is ad~pted to engage the releas~ material or low adhesi~n backsize surface 19 of the ba~king strip 17.
An actuation member 44 is mounted for manually actuated reciprocal movement relative to the housing 20 between a projecting position (Figure 4) with a ~,~tal surface 46 projecting past the open end 26 of the housing 20 to afford positioning t.~e 35 application surface 41 opposite a substrate and a L retracted position (Figure 6) with the application surface 41 and the distal surface 46 of the actuation member 44 generally aligned so that the predetermined length o~ transfer adhesi~e 12 on the backing.strip 17 W093/~4969 . PCT/US92/06669 2 1 1 S 4 i0 - 14 - ~
may be pressed into contact with tha substrate positioned opposite the application surface 41. The actuation member 44 is preferably constructed from a transparent polymeric ma~erial. A user may see the 5 substrata through this portion of the dispenser 10 to afford ~asy, convenient positioning the application surface 41 opposite a substrate. Optionally, visual indicia such a~ arrows may be printed on the actuation member to further assist in locating the adhesi~e 10 '~spotl' on the substrate.
The dispenser 10 also includes advancing means ~8 coupled between the actuation member 44 and the take-up assembly 30 for advancing the predetermined length of the backing strip 17 and the transfer 15 adhe ive 12 along the path to position the predetermined length of adhesive strip 17 along the application surface 41.
In the first embodiment of dispenser according to the present invention, th~ advancing means 20 or assembly 48 comprises a flexible elongate drive member 50 having a first end 51 attached to the actuation member 44 and a T-shaped second engagement end 5~. The take-up core 32 is generally cylindrically-shaped and has a plurality of generally 25 radially projecting drive ribs 54 adapted ~o engage the end 52 of the drive member~
Means such as a sleeve portion 25 of housing 20, mount the elongate drive member 50 on the housing to raciprocably move relative to the housing 20 between (l) a release position (Figure 43 with the second engagement end 52 spaced from the radially projecting drive ribs 54 and (2) an engage position between which release..a~d engage positions the second engagement end 52 is adapted to engage one of the drive ribs 54 (Figure 5) and rotate the take up core 32 t~ advance the length of the backing strip 17 and the transfer adhesive 12 a predetermined length along the path. A
detent surface on sleeve portion 25 fits into a groove WO ~3/(~4969 2 1 1 ~ ~ ~ o Pcr/us92/o6~69 surface on the drive member 50 to limit the m~vement of the drive member 50 relative to the housing 20.
Also preferably the dispenser 10 includes biasing means such as a coil spring 43 for biasing the 5 actuation member 44 toward the projecting position. As 3~e~;t seen in Figure ~, one enà of the-spring ~3 contact~; the sleeve portion 25 and the other end of the ~pring contacts the actuation member 44..
Figures 4 through 6 sequentially illustrate 10 movement of the take-up assembly 30 and drive member 50 of the dispenser 10. When the a;::tuation member 44 is moved from the projecting position toward the retracted position, the elongate drive mem~er 50 moves- from the release toward the engage position. A guide means such 15 as an engagement shoulder S6 is mounted on the housing 20 and comprises f irst 61 and second 62 portions . The f irst portion 61 of the shoulder 56 engages a portion of the T-shaped end 52 and cams the T-shaped end 52 of the drive mem}: ~r SO toward thle drive ribs 54 and guides 20 the end 52 into engagement with a drive rib 54 (Figure 5). As the T-shaped end 52 is engaged with a rib 54 and moves along the f irst and second portions 61 and 62, the take up core 3 2 rotate~; and advanc:es the backing 17 the predetermined length. When the f irst 25 portion 61 of the shouIder 56 :carns the end 52 of the drive member 50 toward the drive ribs 54, the stiffness of the driv~ member 50 biases the end ~2 away from the .:
drive rib 54. Once the T-shaped end 52 of the ~rive member 50 passes the second portion 62, the stif ~ness 30 of the member 50 causes the T-shaped end 52 to "spring"
to ~he side of the shoulder 56 w~ h is opposite: the side facing ribs 54. After the T-shap~d end 52 passes the secan~i portion 62 of the shoulder 56, the shoulder - 56 prevents engagement between the end 52 and the 35 radially projecting drive ribs 54: when spring 43 causes the elongate drive member 50 to move~ back~ to the release position.
Optionally, the f irs~ embodiment of dispenser according to the present invention includes W093/~)4969 PCr/US92/06669 arresting means comprising the take-up core 32 having a ratchet 58 having specially shaped ratchet teeth 59 attached there~o. The housing 20 has a pawl 57 attached thereto. The pawl 57 has an engagement end for 5 engaging the ~pecially shaped ratchet teeth 59 for arresting rotation of the take~up core 32 in a direction other than the advancing direction and for affording intermittent movement of the take-up core 32 in the advancing direction. The arresting means 10 restricts backlash of the backing strip 17.
Referring now to Figures 9 through 14 of the drawing, there is shown a~second alternativ~ embodiment of dispenser. according to the present invention generally designated by the reference.number 100 Which 15 has many parts that are essentially the same as the parts of the dispenser 10. The dispenser 100 is smaller th~n the dispenser 10, is more readily manipulated by a user and requires less storage space.
The di~penser 100 is adapted to ~pply a "sp~t" o~ adhesive 12 to a substrate (~ot shown) from a supply roll 114 of the transfer adhesive 12 comprising a supply core 115 having a through op~ning defined ~y a cylindrical inner surface 116 having an inner diameter 25 of approximately 2.62 centimeters (1.030 inches), and a length of backing strip 17 wound around the supply core 115. The backing strip 17 has first 18 and second 19 major ~urfaces with the transfer adhesive 12 releasably attached to the first major surface 13 and with the 30 second major surface 19 coated with a release means or material.
Like the dispenser 10, the dispenser 100 includes-~ housing 120 having a housing axis A' ~Figure 12), a base wall 121, side walls 122, and surfaces 35 defining an open end 126. Like the housing 20, the housing 120 may comprise a polygonal structure, however, unliXe the housing 20 the housing 120 is sma}ler and more easily maneuvered by a user. For example, the hou5ing 120 may have a width of 5.46 W~93/0~969 ~ 1 1 S ~ 4 o PCT/US9~/06669 centimeters (2,150 inches), a height of approximately 11.94 centimeters (4.700 inches) and a thickness of approximately 2.29 centimeters ~0.900 inches). The housing 120 may be constructed from a material similar 5 to the material used to construct housing 20.
Preferably th2 housing 120 is formed in two pieces including a base portion B' and a c~ver portion C'. The base portion B ' and cover portion C' have cooperable grooves and flanges which afford a removable 10 press~fit attachment of the base R I to the cover C~
portion~ Removal of the cover portion C' affords acces~ to the inner surfaces of the housing 120 so that a user may replace a depleted supply roll 114 with a replacement supply roll.
The housing 120 has an ~uter surface adapted to be manually grasped, a supply roll hub 123 havin~ an arcuate periphery and axially spaced ends. The inner ~urface 116 o~'the supply core 115 is journaled on the periphery of the supply roll hub 123, and~the dispenser 2a 100: includes a mechanism for restricting free rotation of:the supply roll 14 about the supply roll hub 123 similar to the mechanism for the dispens~r 10. Like : th~ dispenser 10, preferably, a friction projection 124 is pr~sent to ~ictionally engage~the inner surface of 25 the supply core 115~ to restrict free rotation of:the supply roll 114.~
Application means are present and~comprise an application member 140 including an a~plication surface ~41 (e~q. a rectangular surface having a width 30 of 1.91 centimeters or 0.75 inches). The application : surface 41 forms a length of the path for the backing :
strip 17, and is adapted to engagP the release material or Iow adhesi~n backsize surface 19 of the backing s~rip 17.
A take-up core 132 rotates about the take-up ~hub ~131 in an advancing directivn and has a portion of the backing strip 17 wound on:its p@ripheral surfaces after application of the adhesive 12 ~o the s~bstrate.
Backlash of the backing strip 17 is reduced by WO 93/049fi9 PCr/US92/1)666s~
2 1 1 S ~
including a friction brake 109 (Figure 10) that engages surfaces of the tak~ up core 132 to restrict fre~
rotation of the take-up core 132.
Path means def ine a path f or the backing 5 strip 17 from the supply roll hub 123 to ths take-up hub 131. Preferably~ the path means comprises a guide member 136 having a land surface 137 projecting from the housing 120.
An ac~uation member 144 is mounted for 10 manually actuat~d reciproc:al movement relative to the housing 120 between a projecting position (Figures ~
and 11~ with a distal surface 146 projecting pa8t the open end 126 of the housing 120 to a~ford positioning the application surface 141 opposite a substrate and a 15 retracted position (Figure 13 )~ with the application surf ace 141 and the distal surf ace 14 ~ of the actuation member 144 generally aligned ~;Q that the predetermined length of transfer adhesive 12 on the ba~king s~rip 17 may be pressed into contact with th~ substrate 20 ps)sitioned opposits the application~ surface 14I. The actuatiorl mem}:~er 144 is preferably constructed from a material similar to th~ material used to construc:t the member 44 and may include similar indicia.:
The dispenser 100 has a different take-up 25 assembly 130 ~ban the dispensex 10. The take-up assembly 130 c::omprises the housing 120 having a take-up .
hub 131, and arcuate gear bearing surfaces 149 (e.~..
cylindrical surfa::es with the radially outer~ surfaces having an inner diameter of approximately 3 . 39 30 centimeters, 1. 330 inches and with the radially inner surfaces having an outer diameter of apprc~ximately 1. 69 centimeters, O. 666 inches) .
The take-up assembly 13 0 includes a take-up c:ore 13~ and,~ the dispenser 100 includes an eccentric 35 orbital gear system comprising a drive gear I02. The d~ive gear 102 is journaled on the arcuate gear bearing surfaces 149 and has a plurality of gerlerally radially outwa;rdly projecting drive ribs 154, and radially inwardly projecting teeth 155. The take-up assembly W093/~4969 ~ll5~ln PCI`/US92/06669 130 includes a driven pinion gear 106 having an outer diameter of about 1.27 c~ntimeters, 0.5 inches. The :~
driven pinion gear 106 is attached to a take-up core -~
132 and has an axis offset from the axis of the gear 5 bearing surfaces 14g. The driven pinion gear 106 includes radially outwardly projecting teeth lOi adapted to engage the teeth 155 of the drive gear 102 to provi~e a gear ratio of approximately 2:1.
The take-up core 132 has arcuate inner 10 surfaces and those inner surfaces are journaled on the peripheral surfaces of the take-up hub 131 ~Figure 11).
Both the take-up core 132 and:the drive gear 102 rotate about axis and those axis are spaced from one another.
.
~ike the advancing means 48, the advancing means 148 is coupled between the actuation member 144 and the take-up assembly 130 for advancing the predetermined length of he backing strip 17 and the transfer adhesive 12 along the path t~ posi~ion the 20 predetermined length of adhesive strip 17~along the application ~urface 41. Also9 the advancing means 48 comprises a flexible elongate drive member I50 having a first end 151 attached to the actuation member 144 and a T-shaped secon~ engagement end 152. ~
Unlike the dispenser 10, the dispenser lO0 includes means mounting a drive member 150 on the :housing to reciprocably move from (1) a release position with the second engagement end 152 spaced from ~:
the~radially projecting drive ribs 154 to (2) an engage 30 position between which release and engage position~ the second engagement end 152 is adapted to engage one of the ribs 154 o~ the drive gear 102 which rotates the driven ~linion gear 106 which in turn rotates the take-up core 132 to advance the length of the backing 35 strip 17 and the tran~fer adhesive 12 a predet~rmined length along the path.
The dispenser lO0 includes means such as a sleeve portion 125 of housing 120, which mounts the elongate drive member 150 on the housing 120 to ~9~/049fi9 PCTtUS92/0~669 i0 20 reciprocably move relative to the housing 120 from (1) a release position with ~he second engagement end 152 spaced from the radially outward projecting drive ribs ~54 to (2) an engage position between which release and 5 engage positions the ~ecnnd engagement end 152 is adapted to engage one of the drive ribs 154 (Figure 12) and rotate gear 102 which rotates gear 106 and take-up core 132 to advance the leng~h of the backing strip 17 and the transfer adhesive ~2 a predetermined length lO along th~ path. A detent surfare on sleeve portion 125 fits into a groove surface on the drive member 150 to limit the mo~ement of the drive member 150 relative to the housing 120.~
Also preferably the dispenser lO includes 15 biasing means such as a torsion spring 143 for biasing the actuation member 144 toward the projecting position, As best seen in Figure 12, on~ end of the spring 143 is mounted on a shoulder in driv~ member 150 and the other end of the spring 143 is mounted to the 20 housing 120.
Figures 11 through 13 sequentially illustrate movement of the take-up assembly 130 and drive member 150 of the dispenser 100. When the actuation member 144 is moved from the projecting 25 position toward the retracted positi~n, the elongate dri~e member 150 ~oves from the release toward the~
engage position. A guide means such as an engagement shoulder is moun~ed on the housing 120 and comprises first 161 and second 162 portions. The first portion 30 161 of th~ shoulder engages a portion of the T-shaped end 152 and cams the T-shaped end 152 of the drive member 150 toward the drive ribs 154 and guides the end !
152 int~ engagement with a drive rib 154 (Figure 12).
As the T-shaped end 152 is engaged with a rib 154 and 35 moves along the first and second portions 161 and 162, the gear 102 rotate which in turn rota~es gear 106 and take-up core 132. Rotation of take-up core 132 advances the backing 17 the predetermined lengthO
W~3/~4969 2 1 1 5 ~ ~ O PCT/US92/0~669 When the first portion 161 of the shoulder 156 cams the end 152 of the drive member 150 toward the drive ribs 154~ the stiffness of the drive member 150 biases the end 152 away from the drive rib 154. Once 5 the T-shaped end 152 of the drive member 150 passes the second portion 162, the stiffness of th member 150 caus~s the T-shaped end 152 to "spring" to the side of the shoulder 156 which is opposite the side facin~ ribs :~
154. After the T-shaped end 152 passes the ~econd 10 portion 162 of the shoulder 156, the shoulder 156 acts as a barrier to prevent engagement between the end lS2 a~d th~- radially projecting drive ribs 15~ when spring :-143 causes the elongate drive member 150 to move:back to the release position.
Optional~y, the dispenser 100 may include arresting means to re~trict backlash of the backing strip 17. The arresting means comprises the drive gear 102 having a ratchet 158 havi~g specially shaped ratchet tseth lS9, the housing 120 having a pawl 157 20 with a dist~l engagement end for engaging the specially shaped ratchet~teeth 1S9 for arresting rotation of the drive gear 102 in a direction other than a direction which moves the take-up core 132 in the advancing direction and for a~fording intermittent movement of 25 the take-up core~132 in ~he advancing direction.

:Operation The operation of the dispenser according:to 30 the present invention will now be described with ~reference to th~ first embodiment of dispenser 10.
Initially a user manually grasps the housing 20 and ` sele ts.a~position on a substrate for application of a - '~spoti' or predetermined length of adhesive 12. The 35 user may look:through transparent actuation member 44 : . to precisely position the dispenser 10 adjacent the substrate. The user then simply presses the housing 20 axially downward ~oward the substrate. Such manual WO93/049fi~ PCT/US92/06669 pressing moves the housing 20 relative to the actuation member 44.
Upon movemen of the actuation member 44 from the pro3ecting (Figure 4) toward the retracted 5 position (e.g. by manually pressing the housing 20 downward toward the subs~rate)~ the advancing means 4~
advances the predetermined length of the backing strip 17 and the transfer adhesive 12 along the path to position the predetermined length of adhesive strip 10 along the application surface 41. The downward pressure on the housing 20 causes the application surface 41 to press against the substrate causing the transfer adhesive 1~ to adhere to the subs~rate. Once the downward pressure on the housing 20 is released, 15 the sprin~ 43 biases the actuation member 44 from the retracted position to the projecting position, and the transfer adhesive 12 that was pressed against the substrate tears from the backing strip 17 and adheres to the sub trate.
The present inventi.on has now been described with reference to several embodime~ts thereof. It will be apparent to those skilled in the art tha~ many changes can be made in the embodiment described without departing from the scope of the present invention.
