19 claims. (ci. 164-49) The present invention relates to a tape dispenser. and particularly to an automatic tape dispenser which is adapted to dispense a sticky surface tape from a roll, cut the same into short lengths, and deliver said short lengths to the operator.

One object of the present invention is to provide a tape dispenser and cutter which is adapted to pull a sticky surface tape, such as surgical tape or the like, from a supply roll, and deliver the same cut into short` predetermined lengths. Another object of the invention is to provide a tape dispenser of the type referred to in which the adhesive of the tape is utilized to support the same during the cutting operation and during delivery. Av further object is to provide a dispenser of the type described wherein the tape is properly fed to the cutting knife, and the knife is actuated at the proper time through the actuation of a single operating member. And yet another object is to provide a tape dispenser of the type described in which the knife is spring actuated and is placed under tension by the tape feeding member. Another object is to provide a tape dispenser which can be actuated by one hand, thus leaving the other hand for the removal of the cut tape from the dispenser, whereby the speed at which the device can be actuated is limited only by the speed with which the operator can remove the cut tape therefrom. And yet another object is to provide ya tape dispenser in which the tape is supported and held at spaced intervals on pins by the adhesive thereon, and in which the knife is adapted to cut the tape between the points of'support whereby the cut strips remain on said pins after being cut and are delivered to the operator who picks them oil? of said pins. And still another object is to provide a tape dispenser and cutter of the type described which is simple in construction, emcient and rapid in operation, as well as cheap to manufacture.

The novel features that I consider characteristic of my invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and its Fig. 1 isV a side elevation of the dispenser,4

with one side of the casing removed, and showing a preferred embodiment of the present invention' in its inoperative position.

Like reference characters refer to corresponding parts throughout the drawing.

Referring now to the drawing, and particularly to Figs. 1-5, wherein a preferred embodiment of the invention is shown, the automatic tape dispenser and cutter comprises an elongated base Ill to one end of which a pair of slotted standards II may be bolted to rotatably support a supply roll I2 of sticky surface tape T. Throughout the specification and claims, when a tape is mentioned, a tape having a sticky surface, such as surgical tape, or a tape having a dry adhesive rendered sticky by the application of a liquid thereto prior to being fed into the dispenser and cutter, will be referred to. A pair of plates I3 and Il extending vertically; from either side of the base I0 serves to support, as well as to enclose, the mechanism making up the device, and While these plates could be integral with the base so that the three parts would form the support for the several parts of the device, to aid in the assembly of the device,

the plates I3 and I4 are shown detachably connected to the base IIlvby bolts I5. The top of the dispenser may be enclosed by a cover I6 overhanging the side plates I3 and I4 and attached thereto by bolts Il. The space between the ends of the plates I3 and I4 is partially closed by plates I8 and I9, but an openingis left at the lower rear end of the plates as shown at 20 to permit'the taper T to enter the dispenser, and an opening is left at the front ends of the plates to permit the tape feeding member to operate as will be hereinafter described. The lower front corner of the plate I3 ls cut away, as indicated at 2l, to permit the operator to remove the cut strips from the tape carrying member, as will be hereinafter fully described.

Rotatably mounted between the plates I3 and I4 is a disk 25, said disk being attached to a shaft 25 the ends of lwhich extend through and are rotatable in plates I3 and I4. Extending axiallyfrom one face of the disk 25 are a plurality of pins 26 adapted to be engaged by the sticky surface of the tape T, and these pins are spaced from one another circumferentially o! the disk 25, as, shown, so that the tape T is supported only at spaced intervals. In order to provide a more satisfactory affinity between the tape T and the pins 26 the surface of said pins, p

if desired, may be roughened by a flue knurling, although such a surface is not illustrated in the drawing. The disk 25 is provided with a plurality of slots 21 extending from the periphery of the disk and radially thereof so that the ends of said slots are below the path of the tape T when said tape is supported by the pins 26. These slots 21 are spaced circumferentially of the disk from one another so that oneslot is located intermediate each pair of adjacent pins 26.

From the other side of the disk 25 a plurality of studs 2B extend, and these studs are spaced circumferentially around the disk from one another to constitute a part of the disk advancing mechanism by means of which the tape T is advanced step by step as will be hereinafter fully described. As shown, the studs 23 are integral with the pins 26 and consequently in axial alignment therewith, however, it is pointed out that the studs 28 may be separate from the pins 26 and may be spaced circumferentially of the disk from one another to suit the tape feeding requirements desired. The disk advancing member 29 is pivoted at one end to a stub shaft 30 extending transversely of the plates I3 and I4 While its other end extends through an opening in the front wall I9 of the dispenser and is provided with a finger piece 3l to which downward pressure can be applied by one finger to actuate said member. This advancing member is normally moved to its raised, or inoperative, position by a spring 22 one end of which is connected to the member 29 at 23 while the other end is connected to a pin 24 extending between the plates I3 and I4.

Pivoted to the disk advancing members 29 at 32 is a ratchet-type pawl 33 which is normally moved toward the path of the tape engaging pins 26 by a spring 34. Referring to Figs. 1 and 2, when the disk advancing member 29 is in its raised position, the pawl 33 is adapted to snap over and positively engage one of the studs 28, and during such time the disk is at rest. When the advancing member 29 is depressed from its inoperative position shown, the pawl 33 will be pulled downward therewith and will serve to advance the disk one step to pull a given amount of tape from the supply roll and advance it beneath the knife hereinafter described. The pawl 33 is provided with the customary cam face 36 which would, when the member 29 and the pawl 33 are returned to a raised position as to advance ing studs on the disk and thereby cam the pawl l over the succeeding studs. It will be readily understood that the inside edge of the pawl including the protuberance will, during the return stroke of the pawl, normally engage the pin stud 29 engaged during the advance of the disk, and by making the contour of said protuberance31 gradual, as shown, the pawl will be smoothly and quietly removed from the path of the succeeding stud 23 prior to the cam face 36 of themsame engaging said stud, whereby the noise and mechanical wear due to impact is overcome. It will be readily understood that the protuberance 31 is so formed as to allow the pawl 33 to drop into engagement with the succeeding stud 28 when the pawl and the member 29 are moved by the spring 22 to their raised or inoperative positions.

The tape T supported on the pins 26 is adapted to be cut by a knife mounted to reciprocate substantially transversely of the path of the tape as will be now described. Pivotally mounted at one end on a sub-shaft 40 extending between plates I3 and I4, and to one side of the disk 25, is a lever 4I. To the free end of the lever 4I is fastened by bolts 42 the knife supporting member 43. The knife supporting member is arranged to extend transversely of'the disk 25 whereby it will engage the periphery of said disk when moved toward the cutting position if a slot 21 is not located in the path of the same. A knife 44 is detachably mounted on the supporting member 43 in any suitable manner, herein shown as being gripped between the supporting member and a plate 45 connected thereto'by bolts 46, and is located on the end of said supporting member extending to the side of the disk 25 on which the pins 26 are mounted, whereby the knife is adapted to move down across the tape T but will not engage the disk 25 at any point.

The knife supporting member 43 is connected to the disk advancing member 29 by a spring 41 one end of which is connected to a pin 48 on the knife supporting member, and the other end of .which is connected to a pin 49 on the disk adserves to positively engage and move the knife to l its raised position when the disk advancing member 29 is moved by a spring 22 to its raised position, and'it holds said knife in its raised position during the first part of the downward movement of the disk advancing member as will now be clearly pointed out. When the disk advancing member 29 is moved from its raised position to advance the disk 25, the spring 41 will tend to pull the knife 44 into its cutting position. The lever 5I, however, due to the fact that it is located nearer the pivot point of the member 29 -than is'pawl 33 will positively hold the knife in a raised position until the slot 21 under the knife supporting member 43 at the time is removedy from the path thereof. Upon further movement of the ,member 29 the lever 5I will release the knife lever 4I, but since the slot 21 has been ,moved in the path of the knife supporting member 43, said member will engage and ride on the periphery of the disk to be constantly held in a raised position. This condition is illustrated in Fig. 5 where the relative positions of the knife and disk are shown when the disk advancing member 29 is approximately one-half depressed. Meantime the disk advancing member 29 is being further depressed whereby the spring 41 is being tensioned, and when the member 29 has been fully depressed to advance the disk 25 enough to bring a succeeding slot 21 into the path of -the knife supporting member, the knife will be snapped by said spring with considerable force across the path of the tape to sever the same. This occurrence will be repeated every time the disk advancing mechanism is released and actuated so that the tape will be cut into strips the length of which will be equal to the space between the slots 21 in the disk. Inasmuch as the tape is cut on both sides of each pin 26, see Fig. 1, the severed section will remain on the pins 26 due to the adhesive thereon and will be carried during the advance of the disk to the opening 2l in the side plate .I3 where the operator can lift it from said disk.

The tape T is fed from the supply roll I2, through the opening in the rear end of the dispenser, and under a guide roller 6D which is rotatably mounted on the sub-shaft 36, said guide roller directing the tape substantially tangentially onto the pins 26 as the disk 25 is rotated. In threading the dispenser the end of the tape will be stuck to the first one or two pins 26 after which the adhesive tension between the pins and the tape will be sufficient to pull the tape from the roll I2. It will be readily understood that the tape is picked up by succeeding pins 26 in a manner to make that portion 0f the tape between any two pins reasonably taut, and since the knife strikes these taut sections with a considerable force, the tape is readily severed without pulling the sections from the pins 26. A spring member 6I extending from the side plate i4 againstV the periphery of the pins 26 may be provided to press the tape against the pin just ahead of the knife, and a roller 62 may be rotatably mounted on the pin 24 to have rolling engagement with the pins 26 when the disk is advanced, and for engaging and pressing the severed sections onto the pins after they have been cut. Thus the spring member 6I and the roller 62 merely serve to insure a firm adhesive contact between the tape and the pins both in advance of, and after passing, the knife so as to insure against the tape being pulled from engagement with said pins.

To prevent accidental backlashing of the feeding disk 25, a stop member 63 is pivoted to a standard 64 on the base l0 to engage the stud 28 on the side opposite to the direction of advance of the disk. This stop member is nor-- mally moved to a vertical position in the path of said studs 28, in which position it can be limited in anysuitable manner, by the spring 34 connected to the pawl 33, which spring is connected to a pin 65 on the stop member. When the disk is advanced, any one of studs 28 engage the stop member 63 and pivot it to the left, viewing Fig. 1, and`when the stud passes the same and the disk 25 stops in a position of advance, the stop member snaps behind the stud to prevent a backlash of the disk.

From the foregoing description, it will be seen I that operation of the disk ladvancing member 29 serves both to advance the tape T under the knife va given amount, and to place the knife under tension, each time it is depressed; and the knife is held in the inoperative position by the disk until said disk is advanced a given amount.

While I have shown a disk advancing means having a given step of advance, and which steps are all equal in length, it will be readily understood that the extent oi' the advance of the disk can be suitably altered by changing the length of throw of -the disk advancing member and the relative location of the studs 28 on the disk 25. This dispenser and cutter provides a device whereby a continuous sticky surface tape can be readily, and rapidly, cut into short lengths and delivered to the operator without the operator becoming besmeared or stuck by the knife in the 5 operation. The device is designed to use the adhesive properties of the tape for feeding and supporting the same to and from the knife, and by making use of the adhesive properties ofthe tape the device is rendered simple in construction and 10 efficient in operation.
