13 Claims. (01. 1644.'7)

This application is a continuation in part of the co-pending application of Dimitri L. Gorbatenko and Albert J. Allgoewer, Serial No. 245,100, filed December 12, 1938.

This invention relates to tape dispensers and has for its principal object the provision of means whereby a plurality of rolls of adhesive or surgie cal tape may be maintained for convenient use in hospitals, doctors ofiices, gynmasiums and the like and whereby desired lengths of the selected width of tape may be severed from the rolls as needed. I 1

In general 3 ity of rolls of adhesive or surgical tape and having a plurality of cutting means selectively movable from inoperative to operative positions to sever a. desired length of tape as it is withdrawn from a roll of the desired width.

some simplified structure which would contain a plurality of rolls of tape of different widths;

.* cover them against possible contamination from dust and dirt and. frequent handling, and which would permit of the convenient severing of desired lengths of tape of the different widths when needed. It is a well-known fact that .up to the momentthe common practicehas been to provide a plurality of rolls of tape on a rod bracketed to the walhwhich rolls are-exposed, and from which lengths of the tape are severed by some separate cutting means such as, for example, scissors.

as this specification proceeds. Likewise, other objects of the invention will become apparentand the novelty thereof will be particularly pointed out in the appended claims.

In the drawing forming a part hereof,

Fig. 1 is a perspective view of the multiroll tape.

terms theinvention comprises a container adapted to support'and cover a. plural In hospitals, doctors ofiices, gymnasiums andin fact in all places where adhesive tape is fre-- quently used, there has been a long felt need for That the present invention meets the. need above stated will become quite apparent.

The tape supporting unit is shown to best advantage in Figs. '1, 3 and 4, wherein it will be noted that there is provided'a backi I2, side wings l3 and. a half-bottom M, which, as inthe preferred form'-illustrated,.may be formed from a single piece'of sheet metal or other material bent 5 into the designated shape.j.'I'he upper edge of the back |2 is bent inwardly upon itself to form a flange I 5 bywhich the unit may be secured to a vertical surface by means such as the screws l6 (seeFig.3). f'

The 'conventional'rolls of tape 20 are co-axially supported on a rod 2| [having reduced and squared ends 22. The ends of the rod are retained against rotation by the slotted brackets 23 secured on the inner faces of the wings l3 (see 15 Figs. 3 and 4-) Suitable'spacers 24 onthe rod 2| prevent contact between the tape rolls 20.

Itwill thus be' seen thateach of the rolls 20 is free to turnon the "rod 2| independently of the other rolls, as the tape is fed therefrom.

The tape cutting unit I I is best shown in Figs. 1 and'3- as comprising a bulged housing 28, being, ear-shaped incrosssection, for the cutting elements about to be described, secured to a front 29, there being a top 30 and, a half-bottom '3|, 25

which, with the above-described housing elements,

of the tape supporting unit, are adapted to make a completely enclosed dispenser. I f

The tape and cutting units,- as' stated, are separable so that access may be had to the rod2| for 3 0 refilling the machine without dismantlingthev structure or removing, it from the surface to which it is attached. To this endthe top 30 is slidably received'between' the side wings l3, the

latter having inwardly turned flanges" 32 for pur- 3 5 It will benoted from Figi 3 that the opposed edges of the half-bottoms |4- and13| are spaced apart to define a slot 40 through which the tape is fed from the supply rolls-20.; As a supplement 5 to the connection 'of' the two units provided in the springhook 33, the units arelocked together at' the edges of the half-bottoms |4 and'3| in the manner illustrated in Fig. 3. The edges-of both of thehalf-bottomsMand 3| are turned to, envelop the re-inforcing rods 4| and 42, respec-. tively. A latch 43- (see dotted lines'in Fig. 3) on the endof rod 42 is adapted to engage the end of'rod 4| and thus lock the half-bottoms l4 and 31 together. i f Q Guide members 45, projecting from a bar 46 secured at the edge of half-bottom l4, are provided as a means of maintaining alignment of feed of the tape from the supply rolls 20 .(see Fig. 4).

The cutting elements are mounted on a panel 55 within the housing 28. In the preferred form illustrated four elements generally designated by the numerals 5|, 52, 53 and 54, are shown. Inasmuch as they are basically the same a description of element 5i will suffice. A pointed blade 55 is slidably retained, on a raised portion of the panel, between a pair of guides 55 formed as integral parts of the panel 55. The ends of the guides extend beyond the bottom edge of the panel (see Figs. 2 and 3) and serve as guides, centering the tape in the cutting operation, as will become more apparent when the operation of the device is explained.

Movement of the blade 55 from inoperative to operative positions is eifected by links 51 and 58 connected together for pivotal actionand pivotally connected, respectively, to the back end of the knife 55 anda bracket 59 on panel 56. A spring 60 in the connection between link 58 and bracket 59 normally urges link 58 to .a substantially vertical position (see Fig. 3) and hence through the linkage described draws blade 55 into its inoperative position (Fig. 2).

As an expedient means of actuating the knife there is provided a bar 63, secured on link 58, having a lever 54 projecting therefrom. As shown in Figs. 1, 2 and 3, the levers 64 extend through the housing 28 and move in the slots 65 therein.

Lateral movement of the knives 55 away from panel and out of guides 45, is prevented by keeper'plates 6'6, screwed to guides 45 and cut away, as at 61, to permit free movement of links 51 (see Fig. 2).

Due to the size of the knife in cutting element 54 and the necessary added length of its stroke in the cutting operation, plus the need for insuring its constant alignment, the bar 63 is substantially longer than in the other elements and is. provided with a leg 68 projecting in a plane, parallel to link 58 and connected to the panel 50 for pivotal movement. The connection consists in extending the pin 69, in the connection of .link 58 to bracket 59, through a second bracket 10,'on the end of which pin leg 68 is secured (see Fig. 2).

The operation of the device is as follows: Having first disconnected unit II by releasing the latch 43 and spring hook 33, rolls of tape are placed on rod 2|, and the latter is put in position between the brackets 23. The free ends of the tape are then drawn from the rolls to a point beyond guides 45. Unit H is then connected to unit Hi and hook 33 and latch 43 are engaged. In dispensing, the free end of the selected width of tape is drawn across half-bottom 3| and between guides 56 (see dotted lines in. Fig. 3) and the corresponding lever 64 is pulled down- Wardly to actuate the knife 55. When thus severed the fee end of the tape falls into the vertical dependent position shown in Fig. 3 in readiness for grasping in subsequent. dispensing operations. I

It is believed apparent that the device shown and described herein embodies very desirable features in so far as cleanliness, safety and, efiicient and convenient operation are concerned.
