tates Patent PAPER TWEL DISPEN SERS Moses M. Mareuse, New York, and Louis H. Morin, Bronx, N. Y., assignors to West Disinfecting Company, Long island City, N. Y., a corporation of New York Application January 19, 1955, Serial No. 482,809 11 Claims. (Cl. 312--39) This invention relates to dispensers for delivery of paper towels. More particularly, the invention deals with manually operated means for delivering at least ai short end of paper toweling from the dispenser to facilitate grasping of said end in withdrawal of a predetermined length of toweling from the dispenser. Still more particularly, the invention deals with a positive feed means checking and controlling the length Fig. 1 is a side and broken sectional view of a dis-r7 penser made according to our invention.

Fig. 2 is a partial broken vertical sectional view through one front corner portion of the dispenser, illustrating part of the construction in elevation.

Fig. 3 is a sectional view, substantially on the line 3-3 of Fig. 1, with parts of the construction shown in elevation and with parts broken away.

Fig. 4 is a diagrammatic sectional view substantially on the line 4 -4 of Fig. 1; and

Fig. 5 is a view, similar to Fig. 1, illustrating `a modified form of paper supply.

In Fig. 1 of the drawing is shown a dispenser cabinet or casing 16, generally Vof the type and kind disclosed in `our prior application, Serial Number 470,670 liled November 23, 1954. The casing has a hood 11, pivoted, as indicated at 12. The bottom of the casing has ya discharge opening 13, adjacent to which is a curved wall portion 14 having a cutter edge 15 exposed to the opening 13 for severing paper toweling 16 withdrawn from the cabinet.

4The paper toweling 16 is `of fanfold-type and supported upon a tiltable carriage, indicated at 17, the paper passing downwardly `at the front of the carriage through suitable guides and over a main feed roller 18 and beneath a supplemental feed roller 19.

The

rollers

18 and 19 are shown somewhat in detail in Fig. 3 of the drawing and, in said figure, it will appear that the roller 1S has an` extending shaft 20, on which is arranged a gear 21, which meshes with a gear 22 arranged on a shaft 23 xed in the roller 19, as by means of a set screw, indicated at 24. This construction provides a positive drive between feed rollers. It will appear, however, that the supplemental roller 19 is mounted in downwardly inclined slots 25 in the side walls 26 of the casing 10, so as to provide pressure engagement of the supplemental roller 19 with the main feed roller 18.

Also indicated in Fig. 1 of the drawing diagrammatically is a yoke 27 for constantly urging the stack of fanfold paper in the direction of the forward end of the cabinet in accordance with the teachings in said earlier application.

ICC

Considering now Fig. 2 of the drawing, it will appear that the main feed roller 18 has a bore 28 at the `other end thereof, in which is arranged a shaft Z9 secured to the roller by a screw 30. The shaft 29 extends through one of the side walls 26 and has an integral gear 31, outwardly of which the shaft includes a flattened key section 32, cooperating with a key socket 33 in the hub portion 34 of a serrated handwheel 35. The hub portion 34 has an enlarged key operating cam portion 36 adapted to actuate a pin-type key 37, `as later described.

The hub portion 34 has an enlarged bore 38, in which seats a bushing 39. Mounted on the shaft 29 within the bore 38 is a spring 30, one end of the spring being fixed to 'the handwheel 35, as seen at 41, whereas, the other end 42 of the spring is fixed in the bushing 39. The bushing 39 and end portion of the shaft 29 have registering apertures, through-which a cotter pin 43 is .adapted to pass in coupling the parts together after the desired torsion has been fixed on the spring 4t). The outer end of the hub portion 34 is externally threaded to receive a closure cap 44.

It will appear, from a consideration -of Fig. 2 of the drawing, that the gear 31, together with associated mechanism, later described, is arranged outwardly of the one side wall 26 and inwardly of the side wall 11' of the hood 11 and this side wall will have an `opening 45 extending through the lower edge of the wall to clear the hub 34 in swinging the hood 11 into open position in the operation of refilling the cabinet with paper.

Secured to the inner surface of the wall 2K6, as noted in Fig. 2 of the drawing, is an elongated plate 46, apertured, as seen at 47, to clear the shaft 29 and having a square aperture 48 to engage a square end 49 on a bolt or stud 50 to key said bolt against rotation. The bolt or stud 50 has an enlarged disc-type head 51 with an arc-shaped recess 52 therein, note Fig. 1 of the. drawing. The key pin 37 operates in the recess 52 in the manner later described.

Rotatably mounted on the bolt or stud 50 outwardly of the wall 26 is a gear 53 which meshes with the gear 31. The gear 53 has a socket 54, in which the key pin 37 is mounted, a `spring 55 being seated in a hallowed portion of the pin 37 and in the socket 54 and normally urges the pin outwardly. Outward movement ofthe pin 37 is checked by a plate 56 supported upon and keyed to the end of the bolt or stud 50, the plate also forming a bearing support for a bolt or stud 57 forming the pivotal support for a pawl 58. The pawl` 58 has a weighted end, as seen at 59, note Fig. 1, to constantly urge the pawl into engagement with the gear 53, this pawl serving to check the gear against reverse rotation or, in other words, in a direction opposed to the arrow 59', which is the normal feed rotation of said gear in rotation of the handwheel 35 in the direction of the arrow 60 of Fig. 1.

Normally, the various parts of the sheet delivery mechanism of the dispenser are in the position indicated in Fig. 1 of the drawing with the key pin 37 at one end of the slot 52. By engaging the handwheel 35 and rotating the same in the direction of the arrow 60, the wheel will rotate freely for a partial revolution controlled by the free movement provided in the key aperture 33, as noted in Fig. 1. During this operation, the cam surface 36 of the cam extension 36 will operate Aupon a rounded side portion 37 of the pin 37 to push the pin 37 inwardly to. clear the enlarged disc 51, as diagrammatically illustrated in Fig. 4 of the drawing, in which an irregular section is shown taken through the rounded side portion of the pin 37 and circumferentially along the cam surface 35 of the cam extension 36. This releases the gear 53 for rotation and, lat the same time, allowing the gear 31 and `mail: feed roller 18 and supplemental feed roller 19 to 3 be operated to feed the paper 16 downwardly through the opening 13. This feed,in a partial revolution of the handwheell 35, will be sufficient to extend enough of .the paper toweling to be engagedby the hand and thenbe withdrawn manually from the machine, this :operation continuing until the gear 53 completes one cycle of a revolution, at the end of which the key pin 37 will drop -into the recess 52 and strike-the abntmentat one end of the recess in checking further rotation loi? saidgear and, at the same time, checking removal of the paper toweling from the cabinet. The withdrawn toweling'is `then severed along the edge 15 `and the dispenser .is now .ready ,for the next withdrawal operation. n lt will be .apparent that the complete `discharge ofA paper .can Ibe performed by a series of intermittent rotary operations' ofl the ,hand- Wheel.

Y In Fig. 5 of the drawing, we have diagrammatically shown a modified adaptation of. the dispenser, in"'yvhich we have substituted for the fanfold paper. towelingy illustrated in Fig. 1 of the drawing a roll of paper, lwhich is arranged in a casing 61, generally similar .to `thencas'ing 10. At 52 is shown a hood, similar to the hood 111,( At 63 and 64 are indicated the main and supplementallrollers, between which the paper from the rolltlsgpasses. The same type and kind of operatingmechanism is .employed with the structure show n in lFig. V5bu"t.tl1is mechanism is not illustrated, aside. from .indicating y dotted lines the handwheel 69, which is similar to the'liandwheel 35' The roll of paper fr65 has,` at -one side thereof, a racdial groove, indicated at ,66, to control mountingoffthepaper upon an axis 67, which is `rotatable' inthe fsidefwallsnof the casing, one of which is .indicated .at-.68S Ihe'prirnary purpose of the radial groove 66 is to control positioning of the roll of paper in thecasing, so Vas to maintainthe withdrawn end of the papertoweling at the -upperpo'rtion of the roll, so as to pass downwardly beneaththe supplemental `roller 64 in the manner diagrammaticallyfseen. The structure of Fig. 5 loperates in precisely ,the same manner as the structure shown in the other 'gureswith respect to the removal of papertoweling from thefdispenser. It will, also appearthat, `at .7(l,`I'.have shopvmin one side wall of the hood 62, .therecess for clearing .the shafting of the ro1ler.63 in swinging zthe hood 62 into open position, this Iaperture. beingsimilar to; the'apert'llre 45, as noted` in Figs. 2 and 3 of the'fdrawing For purposes of description,'thefdrive .or feed means ofthe dispenser may beA said to comprise alf'eedcontrol mechanism governingrotation of .thelmain feed roller in control of the, discharge of paper 4,toweling or otherstrip material from a dispenser. This mechanismcornprises the shaft fixed to themainfee'droller'and the"v manually actuated element, such, for example,fas.the.handwheel disclosed, the two gears,the key pin, `which is m v ally maintained in operative position within the reces`s-52 of the stud head 51. In addition to thefforegoing', the mechanism includes the free action of the' rotatable .element on the shaft for `movement of thekey pinintofinoperative position. Further, the mechanismincludesthe pawl 58 which retains the ,two.gearsnagainst,rotation in a reverse direction.
