ceased I Application December 17, 1945, Serial No. 635,559 (6!. 164-845) 1 11 Claims.

Thi invention relates to devices for mounting upon a spool of tape or rlbbonlike material of any type or kind to control removal of predetermined tape lengths whenever desired. More particularly, the invention deals with an attachment adapted for detachable mounting upon a spool and having means for guiding the attachment in circumferential movement on the spool in the operation of removing tape therefrom, and further having means for severing the tape and for engaging a tape end to retain the attachment against shifting movement on the spool. 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 Perspective view of a spool showing one of my improved devices thereon.

Fig. 2 is a side view of the structure shown in Fig. 1, with part of the construction broken away and in section.

Fig. 3 is a view similar to Fig. 2, showing parts in a different'position.

Fig. 4 is a section on the line- 8-6 of Fig. 2.

Fig. 6 is a perspective view of a modified form of device, detached, with the cutter and holder member in open position; and

Fig. '7 is a sectional view through the device of Fig. 6, showing the same applied to the tape spool, only part of which is shown.

The present application constitutes a continuation in part of the structure disclosed in my-prior application Ser. No. 629,082, filed November 16, 1945.

My invention is applicable for use on tape or ribbon like merchandise of any type or kind in control of removal of predetermined lengths-of tape. The invention deals primarily with a dispensing attachment or device for use on gummed tapes, such for example as bandage tapes, Scotch tape, insulation tape, gummed. paper, and so forth. The invention is also applicable for use in dispensing ribbon of any type or kind.

In Fig. 1 of the drawing, I have shown at It a roll of tape having a tubular spool II. At 82 is shown one of my improved attachments or dispensing devices. The device i2 comprises two similar side plates l3 and M, substantially of the form shown at the right of Fig. 1, that is to say, the upper or outer ends of the plates have laterally extending bearing portions I5 and i6 respectively. The inner ends of the plates have inturned retainer flanges ii and i8, which fit within the spool H and are of a greater length than the adjacent portions of the plates. The length of the flanges fl and I8 is such as to at all times retain the attachment against displacement from the spool, allowing for complete dispensing of the tape thereon. For example as illustrated in Fig. 4 of the drawing.

The plates l3 and it are joined by rivet pins 69 and 20. On the pin I9 is mounted a roller 2|, and on the pin 20 is mounted a cylindrical end 22 of a tape cutter and holder member 23. The member 23 is substantially of the section shown in Fig. 2 of the drawing, and is of sufficient length to extend beyond the roller 2| in engaging a tape end 2 or the inner adhesive surface 25 thereof to hold the member 23-on the tape end, as well as to retain the device i2 against shifting movement on the spool of tape. The free end of the member 23 has a bevelled saw-tooth cutter edge 26 to I sever the tape with the member 23 held in the position shown in Fig. 1 of the drawing.

Stamped out from the member 23 is an outwardly extending tongue portion or lip 21, which serves to position a finger of the hand upon the member in applying pressure thereto in the tearing operation of the tape, and also provides a means for lifting the member 23 in swinging the same into the raised position, Fig. 2, thus di'sengaging the same from the tape end 24, leaving said end free for grasping by the fingers of a lution. The device l2 continues to travel around the spool until all of the tape has been consumed.

After drawing a desired length of the tape from the spool, operator moves member 23 downwardly in the position shown in Fig. 1, to hold the tape upon the roller 2|, and with pressure applied to the member 23, by one end, the tape is then drawn backwardly in the direction of the pivot end 22 of the member 23 to tear or sever the tape at the cutter edge 26. The device l2 will then be retained in this position on the spool by engagement of the member 23 with the adhesive surface 23 of the tape end 24.

In Figs. 6 and '1, I have shown an attachment 28, which differs from the device or attachment 12, in that the

side plates

23 and 30 thereof are integrally joined in a cross head plate 3|, having oppositely directed extensions 32 beyond the side edges of the

plates

28 and 30.

With the constructicnshown in Figs. 6 and 'l, the upper ends of the plates 29 and-30 have at one side thereof inwardly directed

tape supporting flanges

33 and 34 disposed over a roller 35, mounted on a rivet pin 33. With this construction, the tape holding and cutter member 31 is pivoted on another rivet pin 38 atthe opposite side of the

plates

29 and 30. The member 31 is similar to the member 23, and forthis reason. no further detailed description is given. The member 31 is adapted to rest upon the

flanges

33 and 34, when in its closed position, as shown in Fig. 'i, and these flanges engage the tape 33 in movement of the member 31 into open position to aid in stripping the tape from the end of the member 31 and also to support the tape in an outwardly extending position to enable the same to be readily grasped by the finger of a hand.

. While in Fig-7 of the drawing the tape 39 is shown as arranged beneath the

flanges

33, 34, in some uses. it may be passed over these flanges and supported thereon by the member 31. In this connection, it will be understood that, in either use, the tape 3-9, with its adhesive side upwardly, is held by the member 31, as is indicated in Fig. '7 of the drawing.

In Fig. 'I, 40 represents a spool of tape, and it will appear that the plate'3i, including the extending ends 32, are disposed within the core 4| of the spool, the same as the flanges l1 and I8.

With the construction shown in Figs. 6 and '7, the attachment or device 28 becomes a permanent attachment to the spool, the

rivet pins

38 and 38 being applied in assembling the device on the spool. This device is of economic construction and for this reason, can be discarded when the tape of the spool is consumed.

Considering Fig. 6 of the drawing, it will appear that the

plates

29 and 30 have outwardly pressed elliptical

finger grip portions

42 and 43, which are engaged by two fingers of the hand in the operation of pulling the tape from the spool. In other words, the device or attachment remains stationary, and the spool itself then moves through the device as the tape is drawn from the spool.

Where the device is used in conjunction with tape or ribbon like products which do not include adhesive properties, the member 23 may be constructed to fit snugly within the bearing portions l and IE to retain the member 23 against accidental displacement when in the closed position, shown in Fig. 1.

It will be understood that in attaching the device i 2 to the spool, the flanged ends of the.

plates are sprung laterally to pass the flanges over the sides of the spool until the flanges I reach the opening ot the core, at which time,

the kind under consideration, come in varying widths and particularly adhesive tapes used for medical purposes.

The attachment is in the form of a U-shaped frame defined by the side plates and the ping or rods joining and spacing outer ends of the plates, the inner-ends of the plates of the frame having means, for example, the inwardly extending flanges i1 and it for retaining the frame against displacement from the spool, while at the same time, providing for the circumferential movement of the frame on the spool.
