8 Claims.

This invention relates to and has for an object the provision of a towel dispenser which, through the instrumentality of a comparatively simple and inexpensive mechanism consisting of but few parts, will automatically become inoperative when a predetermined amount of toweling has been dispensed and cannot then be operated, without first moving the operating handle in a reverse direction from that required to dispense the toweling, whereby to prevent wasteful dispensing of the toweling, as is often practiced where the dispensing means may be repeatedly operated by continuing the rotation of the operating handle in one direction.

Another object of this'invention is to provide a dispensing control means consisting essentially of but two parts which operate responsive to rotation of a manually operable dispensing crank, when the latter has been rotated a predetermined extent in one direction, to automatically restrain the crank from further rotation in said direction,

and will release said crank only when th latter is moved in a reversed direction, the said mechanism being reliable in operation and entirely controlled through. movement of the crank,

whereby the dispensing member may be convena I iently operated with one hand.

I have shown in the accompanying drawings a preferred form of towel dispenser, embodying my invention, subject, however, to modification within the scope of the appended claims, without departing from the spirit of my invention.

Referring to the drawings:

Fig- 2 represents a sectional view on the plane of line 2-2 of Fig. 1;

Fig. 3 represents an enlarged fragmentary perspective view of the dispenser;

Fig. 4 represents a view in elevation of the stop means as when in releasing position;

Fig. 6 represents a view in elevation, of the stop means showing the parts in full lines as just before the dispensing operation is stopped and dotted lines as when locking the dispensing means against further operation;

Fig. 7 is an'enlarged sectional view of a modified form of the invention;

Fig. 8 is an elevation of the modified form shown in Fig. 7.

In accordance with this invention I provide a shoulders 2| and 22 adapted, to cooperate with then operable in the ordinary manner.

dispensing cabinet I adapted to contain aroll of toweling 2 from which-strips aretorn when the toweling is extended'through a dispensing opening 3. The toweling extends between and is frictionallyengaged by feed rollers 4 and 5 mounted in a frame 6 removably housed in the cabinet. The roller 4, as here shown, is in frictional contact with roller 5 and is driven by gears and 8. The gear 1 is mounted for rotation upon the innerside of a wall 9 of the frame 6 on a stud shaft Hi. This stud shaft projects through the wall 9 and a corresponding wall ll of the cabinet and has a crank l2 fixed to its outer end, whereby upon rotation of the shaft the gear I meshing with gear 8 on the roller 4 will cause said rollers to be rotated, whereby to effect a dispensing operation. L

Means is provided, in accordance with this invention, for automatically arresting the dispensing operation when a predetermined length of toweling has been dispensed, which means may be released only by moving the operating crank reversely, whereupon the dispensing means, is As here shown, this means comprises a dog l3 having a slot l4 receiving a pivot l5 fixed to the wall 9. A spring metal disc or like memberlfiis associated with the pivot so as to frictionally hold the dog in any position to which'it is moved. On its ends the dog is provided with stopprojections l1 and I8 which are adapted to engage a peripheral projection I9 of a stop member 20 fixed for rotation with the shaft l0 between the walls 9 and At the ends of this projection 19 are stop the projections l1 and I8. I g g Normally, as will be seen with reference to Fig. 1 the stop mechanism is in position to lock the dispensing means against operation to dispense toweling, the shoulder 2| being engaged with the projection for, such purpose.

To release thestop niechanismin order that a dispensing operation may be carried out, the crank I2 is moved in a counter-clockwise direction, and the shoulder 22 of member 20 will encounter the projection I8 and thereby move the dog I3 bodily, rearwardly and also rock the dog on its pivot so that the projection U will be raised clear of the shoulder 2| and. the parts will assume the released position shown in Fig. 4. The operator may now move the crank I2 in a clockwise direction, whereby to operate the dispensing means in the usual manner. 'When the crank has been turned through the major portion of one revolution the shoulder 2| will enelement. cludes a cabinet 39 on the exterior of which a counter the rounded end 23 of the dog and thereby rock said dog on its pivdt and into the position shown in Fig. 5 to dispose the projection IT in the path of movement of the shoulder 2|. It is thus seen that when the shoulder 2i encounters the projection IT, as shown in Fig. 6, the end of the dog carrying the projection I1 is moved forwardly and downwardly so that said projection I1 and shoulder 2| will be lockingly engaged, as shown in Fig. 1, and the projection I8 is disposed in the path of movement of the shoulder 22. Thus, when the crank I2 is reversed, the shoulder 22 will encounter the projection l8 and release the mechanism, as previously described. It should be noted that the friction pivot arrangement provides for a free pivotal and sliding movement of the dog, but maintains the dog against unintentional movement from any position to which it is moved,

whereby the stop mechanism will operate in a reliable manner at all times;

A dog 24 is pivoted as at 25 upon the wall 9 and is adapted to be moved into and. out of engagement with the teeth of the gear 1 by means of the friction fingers 26 contacting opposite sides of said gear. When the gear I is turned in a reversed direction to that required to effect a dispensing operation, the fingers 26 will cause the dog 24 to move into locking position, whereby but alimited reversed movement will be permitted the dispensing mechanism, this movement being sufiicient however, to release the stop means as aforesaid.

It will be noted that the projection l8 on the dog I 3 will ride upon the periphery of the stop member 28 during a dispensing operation. This tends to move the dog l3 bodily and pivotally so that in some instances, in spite of the friction of the spring disc IS, the projections l1 and I8 would be disposed in inoperative positions with respect to the shoulders 2| and 22 To prevent such unintentional movement of the dog l3 the latter is provided with a projection 21 which is adapted to ride upon the periphery of an arcuate stop portion 28 formed on the outer face of the stop member 20. With reference to Figs. 1, 4, 5 and 6, it is seen that during the time that the projection l8 rides upon the periphery of the member 20, excepting the projection [9, the projection 21 will engage the periphery of the member 28 which is concentric with said periphery of the member 20 and thereby prevent unintentional movement of the dog l3. During the time that the projection I9 is disposed near and between the projections l1 and I8, the projection 21 is clear of the stop portion 28, as clearly shown in Figs. 4, 5 and 6.

Referring to Figs. 7 and 8, the modified form comprehends-the same arrangements and mode of operation as the first described form, but provides the rotatable stop member as a part of the main driving gear instead of as a separate As here shown, this modification indispensing roller frictionally drives a similar roll- -er'31. Upon rotation of the crank 30 the rollers 36 and 3! will be drivenwhereby to dispense toweling in the samemanner as described in connection with the form of the invention hereinbefore described. The gear 34 is stampedso as to provide a projection 38 on one face thereof corresponding to the projection 19. This projection 38 is provided with shoulders 39 and 40 corresponding to the shoulders 2| and 22. A dog 4! is pivoted as at 42 to the cabinet 39 in the same manner as the dog l3 and is provided with projections 43 and 44 on opposite sides of its pivot and. which correspond to projections I! and I8 of the dog l3. This form of the invention operates in the same manner as the one first described herein, and may in some instances be more desirable than the latter, in that it embodies the stop member and driving gear as one unit.
