GUMMED TAPE DISPENSER Filed Aug. 14 1951 k/zmw/ 7/ BY W%eiw% ATTORNEY 'INVENTOR v Patented Feb. 23, 1954 UNITED STATES PATENT OFFICE 2 Claims.

(Granted under Title 2365,;)U. S. Code (1952),

sec.

The invention described herein, if patented, may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

My invention relates to a dispenser for gummed tape.

In connection with adhesive tapes, especially gummed cellulose tapes, which are sold in rolls, difilculty is frequently experienced in loosening the end of the tape when it is desired to unwind a length of tape from the roll. This is especially true of very thin gummed tapes. Accordingly, it is a primary object of this invention to provide highly simplified and inexpensive means for preventing the free end of the gummed tape from adhering to the periphery of the roll of tape, such means being operable to position the free end of the tape in a convenient location to be grasped for dispensing the next length of tape.

A further object of the invention is to provide a simplified and inexpensive gummed tape dispenser which is adaptable to various size rolls of tape, and readily removable from the rolls, so that it may be used repeatedly.

Other objects and advantages of the inven- 1 tion will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a side elevation of a gummed tape dispenser embodying the invention, and showing the same mounted upon a roll of summed tape,

Figure 2 is a plan view of the same,

Figure 3 is a central vertical longitudinal section through the tape dispenser with the same adjusted for severing an unwound length of tape,

Figure 4 is a similar section through the tape dispenser while it is adjusted for unwinding a length of tape,

Figure 5 is a transverse vertical section taken on line 55 of Figure 3,

Figure 6 is a front elevation of the dispenser,

and,

Figure '7 is a perspective view of a pivoted bail or stripper removed.

In the drawings, where for the purpose of i1- lustration is shown a preferred embodiment of The shell 20 comprises a flat top plate or wall 2| having a forward, transverse serrated edge 22, against which the unwound lengths of tape are drawn for severing the same during use of the dispenser. The serrated edge 22 extends for the entire width of the shell 20, as shown. The top plate 2| is bent downwardly at its rear end to form a relatively short integral depending flange or shoulder 23, arranged substantially at right angles to the top plate 2|. An inclined, longitudinally curved extension or tab 24 is integrally secured to the lower end of the flange 23, and extends rearwardly of and below the flange for a substantial distance. The marginal edge of the tab 24 is perferably rounded, as shown.

The shell 233 further comprises opposed parallel depending side plates 25, integrally secured at their upper ends to the opposite sides of the top plate 2i. The side plates 25 extend a substantial distance below the top plate 2|, and are adapted to straddle the opposite ends of a roll 26 of cellulose adhesive tape, or the like. The side plates 25 have aligned openings 2? near their lower extremities for receiving a transverse keeper pin 28, having its opposite end portions 29 bent laterally for holding the keeper pin against longitudinal movement. A slot 30, slightly narrrower than the diameter of the openings 2! is formed in one side plate 25, and leads from the opening 2'! through the marginal edge of that side plate. The slot 38 permits removal of the keeper pin 28, so that the dispenser may be readily removed from the tape roll 26.

A generally U-shaped bail or stripper 31 is arranged inwardly of the side plate 25 and below the top plate 2!. The bail 3| includes straight parallel arms 32, connected at their upper ends by a transverse bar 33, arranged at right angles thereto. The bar 33 is preferably formed at its longitudinal center to provide a forwardly projecting loop or tongue 34, integral therewith, and arranged substantially at right angles to the arms 32; although the angle between the tongue 34 and arms 32 may be varied slightly as preferred. The lower ends of the arms 32 are bent outwardly to provide short lateral trunnions 35, integral therewith and pivotally engaging within aligned openings 36, formed in the side plates 25, above and rearwardly of the openings 27. The ball 3| is freely pivotally mounted within the shell 20, and the bar 33 and loop 34 and freely swingable beneath the top plate 2!. The rearward swinging movement of the bail 3| is limited by engagement of the bar 33 with the shoulder 23, Figure 3.

When the dispenser is installed upon the tape the same after the side plates 25 are passed over.

the ends of the roll 26. The shellZflis loosely mounted upon the tape ro1l,'and freely movazble' radially and circumferentially of the same. Outward radial movement of the shell 26 is limited by contact of the keeper pin :28 with theyborc of the tape roll.

The free end of the tape is initially passed forwardly under the tab 25, and between the top plate 2] and bar 33 of the pivoted bail. The free "end of the tape may now be pulled forwardly for unwinding a desired length of tape. Prior "to severing this unwound length of tape, .the

fshellI2B is shifted radially downwardly, FigureB,

and "also forwardly or clockwise of the tape roll -26. The pivoted bail 3| will adhere to the section of gummed tape above it, and swing rearwardly or counterclockwise, Figure 3, until the bar sa'engages the shoulder 23. The top plate "2'! 'isin'owpreferably pressed against the periphery of the taperollZt, to increase the adhesive bond between the unwound length of tape and loop '34; The unwound length of tape is now severed by tearing it against the serratededge 22.

After a length ofLtape is'thus servered, the section of tape between the top plate 2! and loop "3 adheres to the loop and also to the bar 33.

This section of tape is held out of contact with the periphery of the roll 26 by'the pivoted bail '3l, The shell 20 is now elevated radiallyef the roll 26,, until the keeper pin 23 contacts the surface of the bore of the roll, Figure 4. The shell is. also shifted rearwardly or counterclockwise upon the roll '20. The pivoted bail 3| isat this time swung forwardly or clockwise, relative to the-shell 20, since the bail is adhering to the'section of tape above it, and the free extremity 26' of the tape is now stuck to the periphery of the roll 26,'the-s ame having been forced thereagainst when the top plate 2] was pressed downwardly prior to severing the tape. The radial arms 32 are 'nowcontacting the stops 3?, Figure 4, and-the bail 3! cannot swing further clockwise, with respect to the shell 29. Accordingly, further counterclockwise movement of the shell 28 upon the roll 26 causes the bail 3| to pull ors-trip the fine extremity 26 of the tape away from the periphery of the roll, so that the same is directed upwardly in position to be conveniently grasped by the fingers, as shown indotted lines in Figure 4. A-further length of tape may now be unwound from the roll 26, and theshell 2!] is again shifted radially downwardly, and forwardly'upon the roll "2 6,, Figure 1, and the pivoted bail 3 I again-assumes its 'rearmost position against "the shoulder 23, holding the free section of tape beneath the top plate, 2l' elevated from the periphery of the'r'oll 26. The top plateZl is now pressed downwardly against the periphery of the roll 25, andith'e unwound length of tape is severed by the serrated edge 22. Thesection of tape below the top plate II adheres to the bar 33 and loop 134, as Previously xplained, andis heldoutofcontact with the pe- It is to be understood that the form of the invention, herewith shown and described is to be taken as preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without depart-- ing from the spirit of the invention or the scope .of the subj oined'claims.
