DEVICE FOR DISPENSING AND APPLYING AN ADHESIVE TAPE Filed Sept. 15, 1.95! 2 Sheets-Sheet 2 A 7' TOR/V575 United States Patent DEVICE FOR DISPENSING AND ADHESIVE TAPE APPLYING AN The present invention relates to a device for dispensing and applying an adhesive tape.

An object of the present invention is to provide a device for dispensing and applyingan adhesive tape to a surface.

Another object of the present invention is to provide a device for dispensing and applying an adhesive tape which lends itself to one hand operation, one having a simple structure, one sturdy in-construction and economical to manufacture andassemble, and one which is highly effective in action.

These and other objects and advantages of the present invention will be fully apparent from the following description when taken in connection withthe annexed drawings, in which:

Figure 4 is a fragmentary elevational view of the front portion of the device;

Figure 5 is a sectional view taken onthe line 5-5 of Figure 3;

Figure 6 is a sectional view taken on the line 6-6 of Figure 3;

Figure 7 is a fragmentary elevational view, on'a reduced scale, showing how the device of the present invention is pushed along a surface to be taped;

Figure 8 is an isometric view of a portion of the device;

Figure 9 is an'isometric view of another portion of the device of the present invention;

Figure 10 is an isometric view of still another portion of the invention;

Figure 11 is an isometric view of a blade member used inthe device; and g V Figure 12 is an elevational view similar to Figure 7, showing how the tape is started on the surface of the article to be taped.

Referring in greaterdetail to the drawings in which like numerals indicate like parts throughout the several views, the device of the present invention comprises a handle of U-shaped cross-sectional configuration arranged in an upwardly sloping direction and having aweb 12 and a pairof spaced 'parallel flanges 14 and 16 projecting perpendicularly from theweb 12. The exten'or surface of theweb 12 constitutes a front face and the interior surface of theweb 12 ,constitutes a rear face.

The web, 12 is cut away adjacent one end of thehandle 10 to form a slot in which is mounted a. wound roll of tape having a free end, the roll. being designated by the reference numeral 18in the free end, shown in Figures 1, 3 and 7, being designated by the reference numeral 20: Theroll 18 is mounted upon apin 22 for free rotation while unwinding aboutthe'pin 22 as an axis transverse of the handle 10:and adjacent to;and inwardly of the upper end of thehandle 10. Thepin 22 traverses the slot provided in the upper end portion ofthehandle 10.

The tape on theroll 18 is. of. the type having onetface 2,846,106 Patented Aug. 5, 1958 2 carryingan-adhesive coating with a separable ribbon covering the face havingthe coating. A portion ofthe, ribbon after separation from the tape is shown in- Figures1and3 and designated by thereference numeral 24 The front face of thehandle 10 below and spaced from theroll 18 is provided with aslot 26. Most conveniently, the slotv26 is provided in the web-28 of a channel-shaped piece.30 which has itsflanges 32 and 34 overlying-and embracingly engaging theflanges 14 and 16 of the handle The space between theflanges 14 and 16 adjacent the inner surface of theweb 12 constitutes a tunnel extending along the rear face ofthehandle 10 inwardly from the lower end of the handle 10 -and terminating at a pointadjacent-to and below theroll 18.

Thepiece 30 is provided with a fixedpointed tongue 36 positioned withinthe tunnel so formed so that the point thereof faces toward theroll 18 andis inwardly ofthe-upper wall of-theslot 26 provided in the piece30: The base portion of thetongue 36 is formed contiguously with the web 28of thepiece 30 and is in registry with the slot26 provided in-thepiece 30.

Aguideelement 38 provided on its upper end witha knife blade projects inan upwardly direction from the front face of-thepiece 30 adjacent the lower end of thehandle 10 and has theknife blade, of V-shape, spaced below and in alignment withtheslot 26.

A-block 40'is inserted into the lower end portion of the handle 10with the front face thereof under theweb 12 of thehandle 10 and with its side faces embracingly engaged bytheflanges 14 and 16 of the handle 10.- Theblock 40 is secured to the lower end portion of thehandle 10 by means ofnutand bolt assemblies 42 which extend through appropriately spacedbores 44 in theblock 40 and-alignedholes 46 in theflanges 14 and 16. The lower end portion of theblock 40 is provided with a convexly curved face portion,asat 48 in Figure 9, which provides a tape directing and applying surface as shown in Figures 1, 3,7 and'12.

Thepiece 30 is provided on-its upper end with alip 50 which is received within an appropriately arrangedslot 52 in theweb 12 of thehandle 10 upwardly of an opening 54 providedinthe web 12.

Theblock 40 is provided with abore 54 extending in; wardly from-the rear face thereof and terminating at the rear face-of a chamber 56provided in theblock 40 which has its forward end opening out of the tape directing and applyingsurface 48 of theblock 40. A blade mem{ber 58 having acuttinghead 60 on one end and ahandle 62"on the other end is positioned with the portion adjacent the end having thehandle 62 exteriorly of the rear face of thehandle 10 and with the cutting head 60-within thechamber 56, Theblade member 58 is reciprocatingly mounted in theblock 40 for movement from the position in which the cutting edge of thehead 60 is inwardly of the surface 4810a position inwhich the cutting edge projects .out of. the surface 48'to thereby sever the sepa rated tapeas the latter moves over thesurface 48;.

A portion ofthe-tapereceived from theroll 18 adjacent the free end-thereof is movable in responseto;

unwindingmovement oftheroll 18; the tape moving from the roll-18 intothe tunnel provided between theflanges 14 and 16 of thehandle 10 and uponbeing moved through thetunnel thus 1 formed having in turn the end edge penetrated betweentheseparable ribbon 24 and one face of-tthe tape carryingtneadhesive coating by thehpoint of the tongue 36-10 separate theribbon 24 fromthe tape,

the separated-ribbon 24. being m ved Out ofthe slot 261 in thepiece .30: and; over the knifeblade of the. guide ele;meat 38,-- Thetapa separa ed from he ribb n24,pmeves along .and out of, the tunnel and overthe directing and applying. surface-48 and; backwardly along. inabutflag:

, 3 engagement with asurface 64 to which the tape is to be applied. In Figure 3, thefree end portion 20 of the tape has been secured to thesurface 64 and in Figure 7 theblade member 58 has been manually advanced to a position in which the cutting edge of thehead 60 projects outwardly of thechamber 56, severing the tape and leaving theend portion 20 of the tape securely fixed to thesurface 64.

The portion of the tape still projecting over the forward portion of thesurface 48 may be next applied to another surface to be taped, as shown in Figure 12, by rocking movement of thehandle 10 in a counterclockwise direction to a position in which thesurface 48 is downwardly with an end portion 20' of the tape between thesurface 48 and thesurface 64. The device of the present invention is now in position for moving once more to the upwardly sloping direction position shown in Figures l, 3 and 7, in which the device may be pushed along thesurface 64 drawing from the tunnel formed therein the adhesive tape and applying the same to the surface to be taped. At intervals, theribbon 24 may be severed by drawing the same over the cutting edge or knife blade of theguide element 38.

Although the device has been described for use with an adhesive tape having a separable ribbon covering the adhesive coating on the tape, it is to be understood that it may be used for tape without such separable ribbon.

While only a single embodiment of the present inventionhas been shown and described, other embodiments are contemplated and numerous modifications and changes may be made therein without departing from the spirit of the invention as set forth in the appended claims.
