This invention relates to a gummed tape dispenser.

An object of the invention is the provision of a device for conveniently holding, feeding out,

applying and cutting off the gummed tape.

Another object of the invention is to provide a device which is designed specifically to t conveniently into the hand, for a one-handed operation of feeding out, applying and cutting off of gummed tape.

plied to fragile objects, soft papers or loosely wrapped parcels.

A still furtherobject of the invention is to provide a device for one-handed dispensing of gummed tape which is of such simplified design as to be relatively inexpensive to manufacture and easy to reload and operate. At the same time it is of a rugged construction with a minimum of moving parts to provide and insure long and satisfactory usage.

Still another object of the invention is to provide a device for dispensing gummed tape designed with the safety feature that the cutting blade is normally pivoted into a protective pocket, except during the cutting operation.

With the foregoing and other objects in view, this invention comprises certain novel constructions, cornbinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 2 is a bottom plan View.

Figure 4 is a top plan View.

Figure 5 is a vertical, longitudinal, sectional view.

Figure 9 is a transverse, sectional view, taken on line 9 9, Fig. 5, and looking in the direction of the arrows.

Figure 10 is a perspective view of the stripper.

The application of adhesive tapesin a manually operated 'device has heretofore been proposed. However, in certain heretofore known and used devices, there are certain disadvantages, some of which are the inability of the user to fully manipulate the device with the hand that holds it, the difficulty in arriving at a design which is tailored to fit the hand and which is small and compact, the complication of mechanism with resulting difficulty in loading, and a tendency to pull and tear on delicate surfaces with attending inconvenience.

The present invention overcomes these difficulties and provides a device for dispensing gummed tape, which is not only small, compact and hand-fitting, but which also permits applying tape to delicate surfaces without difliculty. Further, it provides means under control of user to feed out definite lengths of tape before application and cut off.

As will be hereinafter fully explained, the device, embodying the mechanism of the invention, may be used for applying adhesive and gummed tape and for dispensing certain cord or strip materials from a roll or spool. Furthermore, any single unit embodying the invention can be used for dispensing several widths or roll sizes of tape.

Referring to the drawings, in which the preferred embodiment of this invention is illustrated, I designates a housing upon which is positioned a cover 2. A hinge pin 3 pivotally mounts said cover 2 on the housing I. In the sides of the housing I are journal sockets 4. An arbor 5 is journalled in said journal sockets 4. This arbor 5 is provided with transverse ribs 6 to better secure the paper core 'I on said arbor 5. On the paper core I is a roll or spool of tape material 8.

A feed roller 9 is mounted upon the housing I in alignment with said arbor 5. This feed roller 9 is provided with a reduced portion I6, Fig. 8, upon which is mounted a pressed on ring Il. There is an annular groove I2 provided between a portion I3 of the feed roller 9 and the ring I I. In this annular groove I2 is rotatably mounted the stripper I4, Fig. l0. This stripper I4 comprises a semicircular body I5 integral with a jaw I6. 0n the outer edge II of jaw I6 there are serrations for the purpose of stripping the tape from the feed roll 9 as it is being fed out and also for guiding the tape downward and outward towards the cut-off blade. The portion I3 of the roller 9, as well as the ring II is also provided With serrations which prevent the tape from sticking on the feed roll during the feeding operation.

,On the forward end of the cover 2 is a pocket I8, Fig. 5, in which pocket I8 is suitably designed cut-o blade I9. This blade is pivotally mounted on pin 20. A spring 39 is also pivotally mounted on pin 20. The central portion of spring 3U ls coiled around said pin 29, and one end of spring 3D bears against the roof of the pocket I8 and the other end bears against the inside of hollow blade I9, as shown. The cover 2 is provided with a depending lip 2I which forms a protective pocket for the cutting edges 23 of cut-off blade I9 and also serves to strip the cut-off edge of the tape from these cutting edges after the cut-olf operation. The cutting edges 23 serve to cut off the tape during the cut-olf operation at which time they are caused to pivot out on pin `Il and bear against the tape to cut it as hereinafter described. On the lower portion of the `blade I9 are serrations 2li which facilitate the applying of the tape to a surface; the serrations 4hold'the tape securely from slipping during the cut-off operation and thus hold the tape taut while the cut-off point or edges 23 are pivoted out against it to successfully pierce and cut olf the tape.

The cover 2 is provided with sockets 25, Fig. '7,

which are adapted to receive detents 26 when the cover is to be locked upon the housing.

In Fig. '7, at 21, is an upstanding portion of the bottom of the housing; this upstanding portion -is also clearly shown in Fig. 5.

The stripper I4 extends in the path of the tape, as Shown by dotted line A, Fig. 5. It is prevented from rotating with the feed roll during the feed out operation by means of the shoulder 3i bearing against housing I as shown in 5. l-Iowever, if for some reason, it is attempted to cause the tape A to be pulled rearwardly, then `the stripper will grip the tape between the ser- 'rated surface of its jaw Iii and the groove 32 in the outer end of cover 2 as shown in Fig. 5.

On the cover 2 are surfaces 28, Fig. 5, which act -asfguides for the tape A that passes between said surfaces 28 and onto the feed roller Q. The cover 42 is also provided with an opening 32 through which the periferal portions of the feed roller 9i andrring II project for engagements by the operator-s thumb.

It is to be understood that the means employed to cut off the tape causes the tape to more or less be locked between the serrated edge 2li of the cut-oil' blade I9 and the feed roll 9 to be pulled taut as the blade I9 pivots out so that when the cutting edges pivot out against the tape they have a rm surface into which they enter and cut. This action can easily be seen by reference to Fig. 5. As blade I9 is biased the distance between the serrations 24 on it and the surface of the feed roll 9 increases. As a result, since the tape is restrained at both points, it has a tendency to stretch the tape and hold it firm for cutting. Under no other conditions would it be possible to so cut the tape.

assigns In operation, the roll of tape material is placed A Von the arbor 5 and then the arbor 5 is placed in the tape against aforesaid surface and Vilrmly 4 fastens it, then by further downward pressure, the knife I9 is biased causing the cutting points 23 to sever the tape. The tape is then held between lip 2| and stripper I4 until the operator pushes forwardly on the feed roller 9, causing a new supply of tape to be threaded under the cutter blade I9 and upon the object to be sealed.

While I have described the preferred embodiment of the invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which'this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.
