UNITED STATES PATENT *OFFICE 16 Claims.

"The present invention relates to a device for dispensing gummed tape in the format strips which are drawn or pulled off from a roll of the tape and adapted-to be used for sealing and fastening packages, boxes, cartons and the like.

Such gummed tape is customarily in the form of a paper strip having a coating of adhesive, such as glue, on one side. Devices for dispensing such gnmmed tape consist essentially of a chamber or receptacle for receiving the roll of tape, means for guiding a strip of the tape over a moistening device as it is drawn off from such roll, and a cutting device for severing the strip after the desired length has been pulled out of the dispenser and moistened. Examples of such prior devices are to be found in prior U. S. Patents Reissue No. 16,774, and Nos. 1,787,881 and 1,787,882.

It is the general object and nature of the present invention to provide a much improved con struction for a gummed tape dispenser operating upon the foregoing general principles, and pos sessing the advantages of increased safety, economy, eiiiciency and flexibility of operation.

Specifically'one of the primary objects of my invention is to provide an enclosing housing which not only protects the operating mechanismof the dispenser from damage, dirt and deterioration, but also protects the operator from likelihood of injury, particularly from cutting his fingers by inadvertent contact with the tape cutting blade.

Another primary object is to provide a tape I roll' receiving compartment or trough which is .adapted to accommodate rolls of various widths and which also will permit the-roll to be un- :wound easily and without undue friction as the strip is pulled out of the dispenser, but which at? the same time will prevent the convolutions of the roll from becoming loosened, or the roll from unwinding itself;

Another. primaryzobiect of the invention is to provide means for predeterminately regulating the length of tape which can be withdrawn from the machine in a single operation. In conjunction with such measuring means the invention 4 provides means for automatically resetting the measuring device to zero and in a position to repeat its operation immediately upon actuation of the cutting blade. In addition, indicating means is provided which continuously and instantaneously informs the operator of the exact length of strip which is being withdrawn from the dispenser.

The invention also provides an improved con-' struction of water reservoir and brush means for 5 moistening the under side of the tape. Other objects and advantages shall become apparent as the following description proceeds.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following. de-

scription set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mee chanical forms in which the principle of the invention may be used.

In said annexed drawings:

Fig. l is a perspective view of the dispenser embodying the principle of the invention; Fig. 2 is a vertical sectional view of the dispenser; Fig. 3 is a top plan view, with the cover removed, of

' the tape delivery e d of the dispenser; Fig. i is a fragmentary, vertical sectional view taken subs.antially along line 4-4 of Fig. 3; Fig. 5 is a detailed sectional view of the tape engaging friction roller and taken substantiallyalong line.

5-5 of Fig. 3; Fig. 6 is, a detailed sectional view taken substantially along line 6-6 of Fig. 3; Fig. 7 is a detailed sectional view taken substantially along line 'l-l of Fig. 6; Fig. 8 is a detailed sectional view taken substantially along line 8-8 of Fig. 3; Fig. 9 is a detailed elevation, partially in section, of the stop wheel of the automatic measuring device; Fig. 10 is a detailed plan view of one side of the measuring wheel of the automatic measuring device; and Fig. 11 is a detailed sectional view of one of the tape roll receiving troughs and taken substantially along line ll-H of Fig. 2.

Now referring more particularly to Figs. 1, 2, 3, 6 and of a base housing member I with the cover member 2 overlying it and hingedly connected thereto as indicated at 3. The base member I has a pair of compartments or roll receiving troughs 4'and 5 which are parallel to and spaced from each othe As will be seen from Figs. 2, 3 and6, the bottom walls of these troughs 4 and 5 are of curved contounbuttheir side walls are of different over-all widths.

A series of shoulders 'or steps 6, l and 8 are provided in the bottom portion of the troughs 4 and 5 (such steps being shown only in connection with the trough 4 in Figs. 2 and 11) between the juncture of the bottom and side walls of the troughs. The tops of the steps 6, l and 8 are parallel to the bottom wall of the trough and 5 the sides of the steps 6, 1 and 8' are parallel to 11, the device shown therein consists 'such a point between the side walls. These last described steps 6, I and 9 are for the purpose of accommodating tape rolls of various widths. Thus, directing attention to Fig. 11, the distance between horizontally opposite steps can conveniently be made to be la, in., i in., and 15-} in. so that tape rolls of 1 in., 1% in. and 1 in. respectively can be accommodated -by the trough 4 between the sides of the steps 6, 1 and 8. The over-all width of the trough 4 or the distance between its side walls can be made 23*, in. so that a maximum width tape roll of 2 in. can be accommodated. Thus tape rolls" of four different sizes can be used in a single receiving trough. Similarly, the corresponding steps in the-larger trough 6 can be so dimensioned that tape rolls varying from IV: in. minimum size to 3 in. maximum size can be accommodated. A roller 9 is mounted transversely of the trough 4 (also in the trough 5, not shown) and the bottom of the latter has a recess or depression III for clearing such roller. The periphery of the roller 9, as will be seen from Fig. 2, extends slightly above the top of the uppermost step 6 so that it is adapted to be contacted by the bottom portion of a tape roll, outlines of the latter being indicated at R and R. The roller 9 is located at the bottom of the trough 4 and the tape discharge end of the latter, as indicated by the guide boss II, as to serve as a balance and bearing point during the un of the tape roll, whether the latter be of the type which is so wound that the gummed side of the tape is toward the center or towards the outside of the roll. Regardless of the diameter and width of the tape rolls placed in the trough- 4, they will all have the common vertical center lin C. L. Thus the tape roll indicated at R, which is of the gummed-side-toward-the-outside type. will have its center at the point 0. The radius A from the center to the center of the roller 9 makes an acute angle with the common center line C. L. As the tape strip leading from the roll R is pulled away, the latter will be momentarily drawn in a left'hand direction with respect to Fig. 2 and out of contact with the bottom of the trough 4, so that the weight of the roll R will be wholly supported by the roller 9. As soon as the pulling action on the tape is stopped, the roll R is permitted to roll in a right hand direction and back against the bottom of the trough. The upward curvature of the trough to the right of the center line C. L.

i stops any further rolling movement of the roll R.

In the case of the roll indicated at R, which is of the gummed-side-to-the-inside type having its center at O' with the radial line A passing through the center of the roll 9 and making an acute angle with the center line C. L., a pulling of the tape oil from the roll will also tend to move the weight of the latter up onto the roller 9 and oil! the bottom of the trough 4. As such pulling is stopped, any tendency of the roll R a right hand direction will likewise be stopped by contact of the latter with the bottom of the trough 4. Thus the provision of the roller 9 and its location with regard to the bottom of the trough and the center of the rolls R and R operates to permit an easy and frictionless unrolling of the rolls, while at the same time any tendency to unwind or loosen the convolutions of the rolls is prevented due to the friction braking action as the latter moves back into normal position in contact with the bottom of the tape receiving troughs.

torollin' 4 there is located the Adjacent the tape discharge end of the trough uide boss II which has a bottom l2 corresponding with the bottom of the trough 4 and a series of steps l3, l4 and I whose contour corresponds to and is similar to that of the steps 6, 1 and 6. A similar guide boss II with a bottom l2 and steps l3, l4 and I5 is of course also provided adjacent the the larger width trough 6.

A guide or feed plate It adapted to contact the under side of the tape strip is mounted on the base housing member I. Projections l1 overlie the feed plate l6 and are spaced a sufficient distance from the latter to permit the passage of the tape strip. A space l8is left between the projec tions I! for the purpose. of allowing the passage of the gripping tab cut out of and lifted up from the center of the tape strip. I

The cover 2 carries a front wall casting whose bottom surface, along with the contiguous upper guide plate 2| is also spaced from the surface of the feed plate l6 to allow the passage of the tape The intermediate portion of the on the inside of the cover 2 and at the other end is provided adjacent the fully depressed or strip.

The cutter frame 22 is mounted upon the shaft 29 which in turn is Joumalled in the bosses 24 carried by the upper guide plate 2|. The cutter frame is locked to the shaft 23 by means of a set screw 26. An operating handle 26 is located on the upper end of the cutter frame 22. The cutter frame 22 has a transversely extending portion 21 which carries the tape severing knife blade 28. cutter frame 22 mounts the U-shaped tab cutting blade 29. A slot 96 is provided in the top wall of the cover 2 to receive the cutter frame 22. A slot or recess 3| is also provided in the front wall portion 29 to permit passage of the transverse bar portion 21 on the cutter frame 22. Referring to Figs. 1, 2 and 4, it will thus be seen that the cutter frame 22, together with the cutting blades 28 and 29 is normally held in a position within the confines of the cover 2 so that the sharp, cutting edges of the blades 28 and '29 do not protrude where they might be contacted by the'operators fingers, and are also protected themselves against dulling or damage by reason of possible contact with any hard object.

The cutter frame 22 is normally held in upright position by means of the coiled tension spring 32 which is anchored at one end in the boss 33 to the back of the cutter frame.

As will be seen from Figs. 1 and 3, a similar cutter frame structure indicated generally at 22 tape receiving trough 5 and mounted upon a separate shaft 23'. The cutter frame 22' is cutting position.

An idler roller 35 is provided at a point between the guide boss II and the right hand end of the feed plate I6. A similar idler roller 35' is provided adjacent the base of theguide boss H o the roll receiving trough 5. Friction rollers and 36' ar mounted upon the common shaft 31. Rubber sleeves 39 and 39' are carried on the outside periphery of the friction rollers 26 and 36' respectively. Referring to Fig. 2, it will be seen that the tap strip T coming from the guide boss H passes between the rollers 35 and 36, and that the axes of. the latter are located ina common plane with the point of initial contact of the tape strip T with the friction roller 36. Thus, the idler roller serves to hold the strip T in contact with a sufllcient portion of the periphery of the friction roller 36 so as to intape discharge end of shown in full lines in Fig. 3 in sure the proper driving rotation of the latteras the tape is pulled out of the dispenser.

Directing attention to Fig. 5, both the friction rollers 35 and 35' are mounted upon the shaft 31 i A pinion gear 4| is carried by the common shaft 31 and meshes with the larger gear 42.

The gear 42 is supported in one end of the arm 43 of a bell crank lever 44 pivotally mounted upon the common shaft 31 and having the other arm 45 whose end is adapted to contact with flats 45 and 45' on the juxtaposed ends of the shafts 23 and 23' respectively (see Figs. 3, 4, '1 and 8). A leaf spring 45 extends between th hub of the lever 44 and the upper side of the shaft 23, urgingthe arm 45 in upward direction.

- The gear 42 meshes with the large gear 53 carried by the measuring wheel 5|. The tape length adjustment wheel or stop wheel 52 is mounted adjacent the measuring wheel 5| upon the supporting shaft 53, being separated therefrom by the washer 54. The shaft 53 is supported by the arms 55 extending upwardlyand at an angle from the upper guide plate 2|. A coil spring 55 is mounted around the hub 51 of the measuring wheel 5| and anchored at one end to the latter through the pin 58 and at the other end by means of the pin 59 on the adjacent supporting arm 55. A stop pin 50. on the web of the measuring wheel 5| is in circumferential alignment with another stop pin 5| on the adjacent supporting arm'55.

A circular groove 52 is located in the face of cent each one of the dials 5| and 52 respectively. A water reservoir 85' composed of a non-metallic, non-corrosive material such as hard rubber,

Bakelite, molded plastic, glass or the like, is rebase housing portion movably mounted in the and is held in position therein by means of the marginal flanges 8|. Open sided brush holding has the lifting tab '85 and the downwardly ex-' tending leg portions 85 on each end which are adapted to contact with'the bottom of the reservoir 88. The cover plate 84 of course also has openings to accommodate the brushes 81 and 88.

The brush 81 has a backing'plate 88 and a positioning plate 85 whose upper end 9| fits over the top edge of the reservoir 80'. As will be seen in. Fig. 2, the backing plate 88 diverges from the positioning plate 80 and operates to hold the brush 81 in an upright vertical position and away from the wall of the reservoir 85.

A curved separating plate 82' is' carried by the brush 88 and spaces th latter from the brush 81. A light leaf spring 93 is mounted between the brush 88 and the bottom of the reservoir 85 and tends to urge the brush 88 in an upward direction against the bottom or gummed side ofthe I spring the measuring wheel 5| adjacent the stop wheel 52. The groove ment rib 53. A

52 is interrupted by the abutlug 54 on the stop wheel 52 fits into the groove 52. The stop wheel 52 has an abutment rib 55 adapted to contact with the stop pin 55 on the adjacent supporting arm 55.

The inside face of 52 has a series of equidistantly spaced notches 55' which are adapted to be engaged by the end of the detent spring 51 mounted by means of the fastening screw 58 on the inside of the cover A depressing button or pin 59 extends through the cover 2 and contacts with the. detent sprlng 51 for forcing the latter out of engagement with the notches 55'. The stop wheel 52 has a raised, milled edge as indicated at 18 to facilitate gripping by the'operators fingers in rotation and setting of the stop wheel.

the flange of the stop wheel- A downwardly depending boss 1| is provided in the central portion of 2| and has a tapered hole 12 adapted to receive the end of the locking pin 13 which threadably engages the base housing portion l as indicated at 14. A knurled knob 15 is provided on the outer end of the locking pin 13.

Referring to Figs. 1, 2, 4 and 6, it will be'seen thata portion of the periphery of the wheels 5| and 52 extends out through an opening in the cover 2. Indicating numerals are marked on the outer faces of the flanges of the wheels 5| and 52 and their units preferably correspond to the inches of tape strip lengths drawn out of the machine. As will be seen from Fig. 1, indicating markers 15 and 11, in the form of arrows, are place'd on the top of the cover 2 and adjathe upper guide plate vwill rest upon the steps 1 therein.

- tape strip and tape strip.

It has been found that the abovedescribed brush construction has a-much more eflicient moistenlng function than has heretofore been obtained by a single brush, even though of the same over-all size as that of the two separate brushes. A light lifting spring has one end fastened by means of the screw 55 to the under side of the feed plate l5. The free end of the extends through the opening 91 in the feed plate grasping tab 13'. T. cut out of The cover 2 is first thrown back. A roll of gummed tape having a width, for example, of 1 /2 in. is placed in the receiving trough 4 and Another roll of gummed tape of larger width is placed in the receiving trough 5.. Both rolls are so placed that the gummed side of the tape T will been the under side of the tape as it is laid over the boss A' sufllcient length of tape is preliminarily drawn of! of the roll. so as to at least extend under the projections H. The cover 2 is then moved into closed position and locked by means of the locking pin 13. The
