6 Claims. 1

This invention relates to devices for dispensing or removing tape from a roll. More particularly, the invention deals with an attachment adapted for mounting on a tape spool or a spool like supporting body in such manner as to permit circumferential movement of the attachment about the periphery of the spool in the operation of withdrawing the tape from the spool and in providing on the attachment a pivoted cutter and tape holder for severing a withdrawn portion of tape, and for holding the severed end of the tape roll in position to be readily grasped by the fingers of a hand in the operation of removing a further length of the tape. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views, and in which:

Fig. 1 is a side view of a conventional adhesive tape spool showing my attachment arranged thereon.

Fig. 2 is a plan view of'the structure shown in Fig. 1.

Fig. 3 is a partial section on the line 3--3 of Fig. 2.

Fig. 4 is a partial section on the line 4'-4 of Fig. 3; and

Fig. 5 is a view similarto Fig. 3, showing only the frame of the device and showing a modification.

My invention is adapted for use in the removal of adhesive tapes, other gummed tapes or ribbons, such as Scotch, that is pressure sensitive tape and the like, as well as any other type and kind of ribbon like or tape like material mounted on spools. Many products of the kind under consideration are now sold on spools, one of such products being the well known adhesive tape.

Where products do not now come disposed on spools of the general type and kind under consideration, a suitable spool body will be provided therefor.

In showing one adaptation of my invention, I have illustrated at Ill a standard type of spool, such as used for adhesive tape H. The spool comprises side ring like plates l2 joined and spaced by a tubular hub portion 53. The peripheries of the ring like plates have outwardly and inwardly turned beaded edges M, upon which my tape holding and cutting attachment i5 is slidably mounted so as to move circumferentially ofaround the periphery of the spool.

2 the peripheral portion of the spool in the direction of the arrow l6, note Fig. 1.

The attachment is contained substantially within the boundaries of the spool Iii, except for slight encirclement of the beaded edges M. The attachment comprises a frame composed of two similar side plates I! and I8 which fit upon inner surfaces of the ring plates l2, and their outer ends are curled or beaded around the beads M, as seen at 9 and 26, note Fig. 4. The curled or beaded portions I9 and 20 may be defined as channels on the plates IT and I8, and these channels snug ly but freely slide upon the beads I i in the circumferential movement of the attachment I5 The plates 1 i and G8 are joined and spaced by two pin members 2| and 22 which are riveted or otherwise secured to the plates I1 and 18. The pin 2| forms a pivot or hinge mounting for a tape holding and cutter member 23. This member is in the form of an elongated plate, one end of which is fashioned to form a cylindrical pivot or hinge 24 upon the pin 2|. The other end portion is fashioned to form a sharp tooth like cutter edge 25. The end portion 26 of the member 23 having the cutter edge 25 is normally disposed in more or less parallel relationship to the periphery of the spool when in closed position, as seen in Fig; 3. However inwardly of the end 26, the member is offset inwardly to a slight extent to form a rounded portion 2? adapted to rest upon the pin 22. The

member 23 also has a fingerpiece depression 23 between the pins 2 l. and 22 to receive a finger of the hand in firmly supporting the member 23 upon the pin 22 in tearing off an extended end of the tape II at the cutter edge 25.

In Fig. 3 of the drawing, the member 23 is shown in its normal operative position in full lines. When the end of the tape 5 i is being drawn from the spool the member 23 is thrown back on hinge pin 2!. In withdrawing the tape from the spool, the outer surface lid of the tape slides over the pin 22 and When the desired amount of tape has been withdrawn, the member 23 is moved back into its full line position, at which time, the portion 25 will seat upon the other or adhesive surface lib of the tape. A finger of the hand is then applied to the member 23 to support the same firmly upon the pin 22 and the part of the tape extending beyond the cutter edge 25 is turned ofi at said edge. This leaves a member 23. It will thus be seen that when it -is desired to .remove another length of the tape,-a

finger of the hand is placed beneath the end lie of the tape and the end 26 of the member 23, and both are raised, the member 23 detached from the end I I of the tape, after which the tape is pulled by hand. In this operation, the attachment l5 slides or travels along the periphery of the spool in the direction of the arrow [6. The spool is supported between the fingers of a hand in this operation.

It will also be apparent that the adhesion would be between the end i !c of the tape, and the end 26 of the member 23 serves to support this member in its normal or closed position, in which position it is maintained entirely within the circumferential boundaries of the spool.

In Fig. 3 of the drawing, the attachment is shown on a spool from which part of the tape has been removed. The pins 2! and 22 will substantially define the full capacity of tape upon the spool, but at all times, a clearance will be provided between the outer portion of the tape and the end H0 and end portion 26 of the member 23 to facilitate lifting of the member by a finger of the hand. It might also be pointed out that as the member 23 is raised at its pivot 2|, the tape end Hc automatically is displaced from the end 23. It will also be noted that while the attachment serves to hold and support the end lie for accessible removal, this end in engaging the end portion 25 of the member 23 also retains the attachment in a fixed position on the spool against movement in either direction. In this sense, the member 23, in combination with the tape end forms a locking or latching means for retaining the attachment against shifting upon the spool. However, the minute the latch is raised on its hinge, and the tape withdrawn from the spool, the tape in engaging the pin 22 will operate to freely feed the attachment, as previously described.

It will be noted upon consideration of Fig. 4

' of the drawing that the roll of tape H has its side edges spaced from the ring walls l2, as seen at 29 and 3G to avoid frictional engagement therewith. These spaces facilitate positioning of the plates I? and i8 upon inner surfaces of the rings l2, and while this spacing is exaggerated in the present illustration, this exaggeration is for sake of clarity.

In Fig. 5 of the drawing is shown a modified form of frame 3i which differs from the frame [5, simply in forming pivot and bearing portions 32 and 33 respectively, integral with the side plates, one of which is shown at 32, these plates being similar in all other respects to the plates II and it. In other words, instead of employing independent pins, such as 2! and 22, which are riveted into the plates H and [8, a single sheet of material is fashioned to form the plates including the pivot portion 32 equivalent to the pin 2 I, and a bearing portion 33 equivalent to the bearing pin 22. The portions 32 and 33 will be fashioned to the desired cross sectional contour to provide the required supports for a cutter and tape holder, similar to the holder 23.
