Schultz, Chicago, Ill., assignor to National Can Corporation, Chicago, 11],, a corporation of Delaware Filed Jan. 8, 1958, Ser. No. 707,713 6 Claims. (Cl. 22525) This invention relates to a device for dispensing tape from a roll. In particular it has reference to a magazine for receiving a roll of tape and means for facilitating the withdrawal and tearing of a desired length thereof. Such devices may be used for example, in oflices for dispensing pressure sensitive tape for sealing packages, by electricians for dispensing insulating tape, by painters for dispensing masking tape, etc.

The invention is best understood by reference to one field of use to which the device is ideally adapted. Electricians customarily carry a roll of insulating tape hung on a chain and bar forming an attachment of the tool kit worn on the person. After withdrawal and severance of a length of tape the stub remaining on the roll will, nearly always, be returned to the roll proper, if not by design then by the motion of the suspended roll as the tool kit is shifted. Thus, the next operation requires the location of the cut end which is time-consuming, as the color of the tape, e.g'. black, blends the cut end into obscurity; and the bothersome lifting of the cut end outwardly as a tab constitutes an additional nuisance.

My invention has for its principal object the provision of a tape magazine having means for rapidly dispensing a length of tape therefro Another object is to provide a device as aforesaid including means for automatically providing a stub to facilitate withdrawal of a subsequent length of tape.

A further object is to provide a device in accordance with the foregoing having indicia to guard against misuse.

Another object is to provide a device for dispensing tape which is adapted to be carried on the person in a readily accessible manner. Y

Other objects will appear from the ensuing description which, taken with the accompanying drawing illustrates a preferred form which the invention may assume in practice.

In this drawing:

FIG. 1 is a front side elevation of the device;

FIG. 2 is a view from the edge to show certain of the operational features;

FIG. 3 is a cross section taken on the line 4-4 of FIG. 2 to illustrate one operative position;

FIG. 4 is a view similar to that of FIG. 5 to illustrate the other operative position;

FIG. 5 is a cross section takenon the line 5-5 of FIG. 1; and

FIG. 6 is a detail of portions of the device as seen in FIG. 2 to show the same in the other operative position.

Regarded broadly the invention comprises an outer cylindrical cup and an inner cylindrical cup received telescopically and rotatably therein for movement between two positions hereinafter sometimes referred to as Tear and Dont Tear positions. Suitable means are provided intermediate the inner and relative rotation to a predetermined are which means may also serve to retain the cups in operative relation, although separate means are within-contemplation. The cups are provided with flanges to receive the spool upon which the tape is commercially supplied. The inner cup has a slot in its lateral wall through which the free end of the tape is first passed for dispensing and the tape is then passed through an opening in the lateral wall of the outer cup. One edge of such opening is employed for tearing and is desirably serrate to facilitate this step. In

order that a stub may always be made accessible for tearing a subsequent length of tape the lateral wall of the inner cup is provided with an opening so arranged that an end portion or stub of the tape is caused to remain beyond the tear line and overlying a part of the opening. Thatwall of the opening in the outer cup opposite the tearing edge is provided-with a. finger adapted for move ment into the opening in the-inner cup and beneath the stub when the two cups are'relatively rotated whereby the stub is lifted outwardly for easy grasping. "In order that the invention device shall function inthe intended manner it is necessary that the twooperative positions of the rotatable parts he observed for otherwise the stub will not be produced. To this end I provide visible indicia to indicate each of the two operative positions.

Turning now to the drawing I have shown, by way of example, a tape dispensing device in accordance with the principles of the invention comprising an outer cylindrical cup 10 of shell-like form and a'similar inner-cup 11 so arranged that the respective lateral walls 10a andlla are closely adjacent but sufficiently free to permit manual and digital relative rotation thereof and the lodgment of the stub therebetween.

The cups 10 and 11 may be assembled and disassembled simply by forcible movement-in the direction of the common axis. Retention of these parts'in operative relation may be eflected by various means but I prefer-to utilize a plurality of circumferentially elongate depressions 14in the wall 10a engaged with mating depressions 15 in the wall 11a. These depressions arecap'able of providing detent action to retain the cups in their opera tive relation and to serve as stops to limit movement of the cups over a predetermined are between the two on erative positions and as will appear. To this end the depressions 15 are sufliciently" longer than the depressions 14. Inasmuch as the walls 10a and 11a may be of thin gauge material the

depressions

14 and 15 may be readily engaged and disengaged by momentary deformation of the walls.

The cup -11 is provided with an annular protuberance 21, e.g. triangular in radial cross section provided with radial ribs 22 for improving digital grip whereby the cup 10 may be grasped in one hand while the cup 11 may be rotated by the -fingers of the other hand. Any other suitable means may be'used for gripping the cup 11, e.g. holes or depressions for receiving the finger tips. v

Each of the cups 10and llis provided with an annular flange 25 adapted jointly to receive a spool 26 of the tape 27 to be dispensed. If desired the flanges 25 may be'of stepped configuration, frusto-conical or of other suitable form to receive various widths and diameters of spools.

It will be understood that as the 'tape is dispensed the outer cups for limiting the v spool 26 will rotate on the flanges 25. Moreover the axial opening defined by the flanges 25 permits the entire device to be carried on a support, e.g. the bar and chain used by electricians.

Dispensing of the tape occurs with the parts as shown in FIG. 3. As there illustrated a length 27a of tape has been fed through a slot 31 in the lateral Wall 11a, through a substantially rectangular opening 33 in the lateral wall 10a and has been drawn out of the dispenserto, the required length plus some additional amount to provide the stub, e.g. about /2. To avoid snagging of the tape the leading edge 32 of the slot 31-is preferably bent on a curve as shown. 1

Following withdrawal of the tape in the manner just described but prior to severing the same from the supply the cups 10 and 11 are contrarotated to the position of FIG. 4 thereby drawing about /2" of the tape between the lateral walls 10a and 11a where itis lodged pends ing a succeeding operation.- Theresulting stub is cated at 27B. The tape may then be torn on the serrated edge 35 of the opening 33.

i To withdraw a subsequent length of tape the cups and 11 are rotated from the position of FIG. 4 to that of FIG. 3. Thestub heretofore referred to has, due to its backing become adherent to the outer surface of the lateral wall 11a, or if the tape is not of 'cementitious character the stub will be seized between the

walls

10a and 110. In either event the invention includes means for raising the stub to a position where it may be easily grasped for withdrawing a succeeding length.

To this end the lateralwall 11a is provided with an opening 41 and a finger 42 extending from the wall 10a, e.g. from a margin of the opening 33. Finger 42 is in- Wardly deformed in such degree that, during relative rotation of the cups'lfl and 11, the distal end of the same lies within the plane of'the opening 41. The relative rotation, of the cups 10 and 11 is determined so that the' stub overlies the opening 41 .to atline just short of the inwardly-extending distal end of the finger 42, i.e. when the parts are in the position of FIG. 4. Hence, as the cups are rotated from the position ofFIG. 4 to that of FIG. 3 the finger 42 is carried below the stub and the stub rides over the finger thereby to elevate the stub outwardly to a position where it may be easily grasped to initiate a subsequent operation. Inasmuch as the finger 42 is flexible it cannot interfere with assembly and dis-assembly of the cups.

Byre'ason of'the arrangement just described the necessary stub end for starting the withdrawal of a new length of tape is always at hand in a readily accessible location.

It willbe obvious that the alternate contra-rotation of the cups 10 and 11 can be very quickly developed as a correct habit. However, tocounteract any forgetful tendency on the part of the user the present invention includes visual indicia to remind him when the parts are in incorrect positions. Referring to FIGS. 2 and 6 the lateral wall 10a is pierced by a window 51 adapted to register with alternate inscriptions Tear and Dont Tear in the adjoining lateral wall 11a. It will be apparent that when the parts are in the position of FIG. 4 the tape may be torn, as then the desired stub is lodged between the cups. In this case the indicium Tear will appear in the window but when the tape is simply being withdrawn from the spool (FIG. 3) the indicium Dont Tear will be visible. If desired, equivalent tactile indications may be employed.

Whilel have shown a particular embodiment of my invention,-it will be understood, of course, that I do not wish to be limited thereto since many modifications may be made and, I therefore contemplate by the appended claims to cover any such modifications as fall within the true spirit and scope of my invention.
