'i3la1ims. (61.164-43) This invention, antesv to .manuauymanipmable appliance ofsuch character .having unique feeding and severing elements vassociated with simple, rugged anddurable parts 4ior holding the roll of tape as lengths thereof are withdrawn.

One of the important aims of the instant invention is to provide a summed tape dispenser having especially designed severing mechanism, the nature whereof insures aeripping of the .tape adjacent to the lines of Vtransverse severance as the knife structure, forming one of the severing elements, ris `actuated.

Another important object of this invention is to provide a cutter dispenser of the aforementioned character `that receives .a .roll of gummed tape in the magazine thereof, without the necessity of manually adjusting any part other than the swinging .cover of the compartment, which compartment is provided with side plates .shiftable with ease .and dispatch when tapes of diiferent widths are to be used ,in the machine.

. Other objects of the 'instant invention include the provision of an especially formed throat through which the tape passes and in which the .straight length of `tapeis.c oniined while the severing action occurs; :the inclusion of ,a swingable knife assembly that constitutes a part of .the complete housing for lthe elements in Ithe jthroat; v,the provision of an apron pivotally mounted within the throat and movable for rendering the floor of the throat accessible when it becomes .necessary to clean the same; andthe provision of feeding mechanism a part whereof is in the aforesaid throat of the machine and adapted to be swung about a common 4center Ywith the aforesaid apron and said knife structure when the threading action becomes necessary or it is desirable to gain access to the surfaces which contact the .gummed side of the tape.

Still yfurther aims oi theinvention will become apparent to one skilled'in the art, as the specication, referring to the accompanying drawings, is comprehended.

'In the drawings:

Fig. 1 isa top plan View of a gummed tape dispenser made in accordance with the ,present invention.

Fig. 2 is side elevational view thereof.

, Fig. 3 is a vertical transverse .sectional .view

taken on line III-.1110i Fig. 2.

Fig. 4 is alongitudinal sectional view taken on ,line v12V-IV of .Fig..3.

jFig. .5 .is a .fragmentary lplan view -with parts lby "the numeral Il). ,and is preferably formed of 'presented tothe trade inthe form illustrated `in Fig. 4. It is rolled'iipon a core 22 and remains-in a compact, wound -condition as sections of A,the

tape are ,stripped therefrom.

Compartment 24 is formed within the rear part of `frame I2 between the vertical parallel spaced apart sidewalls 26 and 2B of frame I4. These `side Vwalls cooperate with the hood-like cover lf2 in establishing compartment and a forwardly and downwardly inclined transverse floor 30-pre sentsa floorbetween walls 26 and 28 to establish a *throat 32. The rear marginal end of floor 39 is curved as `at `34 Yand-slotted as at 36 to receive adjustable plates 38, to the end that compartment 2li-may bevaried in effective width. Theseplates `38 have-theirfreeends*resting upon the bottom of frame I4 as illustrated in Fig. 4, while their upper and forward ends are contoured to present a head 40, offset in two directions to allow quick removal yet to lock the same in place when-inserted in slots"36.

`When cover I2 is open, these plates may have their Vlowerends lifted vvto free head 4I) fromwithin the slots-thus, compartment 26 maybe varied inf-width to accomodate `a roll 2i] vso long as the width of the roll is less than the distance between `walls 2li and v`28. 'iIn vfact, a roll 2t maybe inserted Vin compartment 24 without the luse Vof plates 38 whenits width so demands.

Atransverse shaftlIZ is journalled in suitable bearings supported by walls 26 and 28. This shaft carries alknife structure, broadly designated by the operator when a severing action is to occur.

Knife structure 44 is maintained in a set position by spring 55, one end rwhereof is clamped to the underside of knife structure -li while the lower free end rests upon apron 52, as illustrated in Fig. 4. A portion of this apron 52 frictionally engages the upper surface of tape as it passes along throat 32. A lip 54 integral with apron 52 and at its forward end, not only insures that spring 58 will remain :against the upper surface of apron 52, but presents a gri-p when the apron is to be lifted about its connec- Y tion with shaft `12. This connection is established by perforated ears 56.

The rear portion of apron 52 is bifurcated to form two legs 58 and to insure clearance for` a knurled roller 80, rotatably mounted upon shaft 62. This shaft is journalled in slotted bearings 64 rigid to the inner face of walls 26 and 28. A spring BS curled about shaft 42 and having ends resting upon shaft 62, yieldably maintains roller against a, wheel 68, a portion whereof extends upwardly to engage with the underside of tape 28 through an opening lll in floor 38 of throat 32.

This wheel 68 is freely mounted upon shaft 12 journalled in bearings on walls 26 and 28, as depicted in Fig. 3. An operating lever or crank 14 mounted upon shaft 'I2 allows the operator to turn this shaft' in the direction of the arrow shown in Fig. 2. A lost motion connection,

Ratchet 18 secured to shaft 12 is engaged by *dog 18 when crank 14' is moved as above described. A stop and return arm 80 mounted on shaft 12 has a spring 82 secured thereto and when the free end of arm' 80 strikes the underside of floor 38, or any other storp provided in the path of travel of this arm, the length of tape 20 which is fed is determined. Upon release of crank 14, arm Bil will move back under the influence of spring 82 to the condition illustrated in Fig. 4 while dog 'I8 freely rides over the teeth in ratchet 16. When such `action occurs, the serrated edge of wheel 68 is engaging the underside of tape 28 While the senrated edge of roller 60 is in engagement with the upper face of tape 2li-thus, a grip at the center of tape 26 is established to feed a length thereof through throat 32 and across the moistening apparatus now to be described.

A pressure applicator 84 pivotally mounted between the two side walls 26 and 28 by a transverse pin 86, overlies the outwardly projected bristles of a brush 88. This brush is mounted in a carrier -98 which has an arcuate lip 92 lying beneath pressure yapplicator 84. When tape 2Q is drawn across the moist ends of bristles 38, applicator 8 will exert enough pressure to insure moistening the adhesive thereon.

Well I6 removably supports carrier Si) and is uniquely formed to lcooperate with the'upfper edges of Well I6. This carrier 98 is substantially U-shaped with the lip 92 on the free end of one of its legs. The free end of the other leg is provided with a hook or rebent portion 94 and opposed notches 96 adjacent lip 92 receive an inturned flange 98 on the top of well I6 when the holder is forced into the well a distance to allow `such relation. When the holder is moved into the well, the legs are compressed or forced together and the inherent resiliency snaps lip 92 outwardly away from hook lSHI to a position shown in Fig. 6, whereupon the brush may be dropped into the carrier to assume the taipe-moistening position with its base at the bight of carrier 98. Removal of the carrier and brush is accomplished merely by squeezing together the free ends of the legs of carrier 98 to disengage notches 95 and flange S8, whereupon the carrier and brush may be lifted as a unit from Well I6.

The operation of the machine has been made clear during the course of the specification, and it will be understood by those skilled in the art and with such equipment, that as a straight length of tape 28 is moved from the roll thereof, apron 52 `will smooth the same against floor 38 of throat 32. The weight of the apron and knife structure 44 will so serve and pressure applicator will guarantee an even moistening action because of its treatment of the tape above the ends of bristles 88. When the tape is ready for severing, the operator forces knife structure 451' downwardly by striking the upper face of the traylike body, whereupon spring 58 is compressed against apron 52. This movement not only `forces blade 45 through opening 48 to cut tape 28, but exerts a pressure upon apron 52 to hold tape 28 tightly against the floor 30 of the throat. Cutter it of the knife structure has its edge contoured to enter the tape at its center, to avoid any tendency to move the tape laterally within throat 32 and to preclude any effect which may pull the tape into opening v158.

If the floor of throat 32 becomes coated with adhesive from tape 23, and such is the case of machines of this character, it may be washed or cleaned by lifting knife structure M, apron 52 and roller E@ upwardly around the axis of shaft 42. When such is done, the oor of throat 32 is fully exposed as is the knurled edge of wheel 68 projecting through opening 18. The parts may be quickly and conveniently Washed, and since well I6 is removable forwardly upon the application of an upward and outward force, all of the component elements of the machine `are readily accessible.

Obviously, tape handling equipment having appearances, form and modes of operation different lfrom those above specified may be made without departing from the spirit of the invention or scope of the appended claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
