3 Claims. (Cl. 2712.'4)

This invention relates to improvements in sheet or web dispensing apparatus, and more particularly to an improved apparatus for dispensing paper toweling in'predetermined amounts.

Dispensers for paper toweling are well known and largely used in washrooms frequented by the public, and in washrooms frequented by employees of industrial plants, ofiices, and the like. It has been proven to be economical to limit the amount of paper toweling withdrawn from a dispenser with each hand operation. However, in constructing a dispenser which will serve such a purpose, it has been necessary to utilize numerous moving and complexly associated mechanical parts in order to give a dispenser which will properly limit the amount of toweling dispensed with these hand operations.

Accordingly, it is an object of this invention to provide a paper toweling dispenser capable of delivering a predetermined amount of toweling with each hand operation, wherein the mechanism for accomplishing this purpose is simply and economically constructed and consists of a relatively few number of moving parts thereby further decreasing maintenance problems.

Another object of this invention resides in the provision of an improved toweling dispenser, wherein only a predetermined amount of toweling may be withdrawn from the dispenser after a single hand operation.

Still another object of this invention is in the provision of an improved toweling dispenser having mechanism for permitting only a predetermined amount of toweling to be withdrawn from the dispenser subsequent to a single hand operation, wherein the relatively small number of parts involved permit the construction of a complete and extremely compact toweling dispenser.

Other objects, features and advantages of the inveniton will be apparent from the following detailed disclosure taken in conjunction with the accompanying sheets of drawing, wherein like reference numerals refer to like parts, in which:

' atent Patented July 26, 1960 from a storage chamber to a feed or measuring roller, and

through a delivery opening to the user upon actuation of the feed mechanism. Depressing of the control button initiates the operation of the feed mechanism to eject a certain amount if toweling at which time the ejected toweling may be grasped in order to pull more toweling out of the cabinet until a predetermined amount is withdrawn. A stop mechanism limits the maximum amount of toweling that may be withdrawn from the cabinet with each hand operation regardless of Whether the push button is held in a depressed position or not. The relatively few number of moving parts which make up the feed or measuring mechanism not only permits cheaper construction but provides easier operated dispensing apparatus and eliminates a complex mechanism which might require considerable maintenance.

The toweling dispenser illustrated in the drawings for purposes'of exemplifying the present invention includes generally a toweling dispensing mechanism which feeds or measures a predetermined amount of toweling during each operation thereof, and a cabinet or housing for enclosing the mechanism and storing a supply of toweling.

The cabinet includes a cabinet having a rear wall 10, parallel opposed side walls 11 and 12 and a bottom 13. A toweling storage chamber or cavity 14 is defined by the side and rear walls, and the side wall 12 is spaced inward 1y from the ends of the rear Wall and bottom to further define an end chamber 15 which houses most of the dispensing mechanism.

The cavities 14 and 15 are enclosed by the cover 16 which includes a front wall 17 connected at its upper end to arearwardly slanting panel 13 which in turn connects to a top wall or panel 19. Side walls 2% and 21 complete the cover, and the cover is hinged to the upper end of the rear Wall 10 by a transversely ext-ending hinge 22, Fig. 1. Holes 23 (only one shown) are provided in the rear wall 10 in order to hang the toweling dispenser on suitable hanging members of a building wall. A locking mechanism 24 coacts with a locking tab 25, Fig. 1, which is mounted on a cross bar 26 extending between the side walls 11 and 12 in order to selectively lock the cover into closed position over the cavities 14 and '15. A delivery opening 27 is provided in the bottom wall 13 of the cabinet for delivering toweling from the cabinet, and the forward part of the opening is defined by a tear plate 28 having a lower serrated edge against which paper toweling may be pulled for severing purposes.

I Within the toweling storage cavity 14, a roll of paper toweling 29 is supported at its opposite ends on inclined guideways 30, Fig. 2, and the web of the toweling is drawn from the bottom of a roll and trained between a 1 lower feed or measuring roll 31, Figs. 5 and 6, and an upper presser roll 32. From the coasting rolls, the paper is trained downwardly over the surface of the feed roll 31 and through the delivery opening 27.

The presser roll 32 is mounted on a shaft 33 guidedly supported at opposite ends in downwardly inclined slots 34 and 35, and it is constantly biased against the paper toweling and feed roll 31 by a spring 36 at each end thereof (only one shown). The spring 36, Fig. 6, is secured at one end to a pin 37 on the side wall 12 and at the other end to a bracket 38 journalled on the presser roller shaft 33. The presser roller 32 is provided with a plurality of spaced reduced diametrical portions 39 which freely receive fingers 40 of toweling guide members 41, Fig. 1, which prevent the toweling from adhering to the presser roller wherein it might be carried around the roller and beyond the limits of the guide member so that a user could not pull the toweling through the delivery opening 27.

The dispensing mechanism is constructed so that upon depressing of the button or knob 42, Figs. 1, 2, 3, and 7, the feed or measuring roll 31 may be rotated through one revolution thereby dispensing a length of paper equal to. the. circumference ofthe feed roll. Accordingly a variation in the diameter of the feed roll 31 would. give variation in the amount of paper delivered. from the cabinet by the dispensing mechanism. The knob 42, is secured on theend of a push-pull rod 43 which is slidably received. within a tubular guide 44 secured to the front wall 17 of the cover 16. The knob *42 is spherical in shape and. arranged to telescope over the tubular guide, 44, and. is. normally positioned as shown in Figs. 2 and 7 by the biasing of a spring 45 arranged about the rod 43 and abutting at one end against the inside of the knob. 42 and, at the other end against the tubular member 44.. In order to limit the outward movement of the knob 42 and. the rod 43, a cotter pin 46 or like element is mounted in the rod 43 and adapted to define a stop for hearing against. the inner end of the member 44 when the rod 43 is in. its out position.

The feed or measuring roll 31 is mounted on, a, shaft 47 which is rotatably supported by the. side walls 11 and 12 with the end of the shaft at the side wall '12 extending into the end chamber 15 and having mounted thereon for corotation therewith a flywheel or disc wheel 48. This flywheel has a detent or pin 49 carried at a point outward at the center thereof and extending from the side remote from the feed roll 31. The flywheel 48 is continually urged to the position shown in Fig. 3 by a spring 50 connected at one end to a lug 51, Figs. 1 and 5, mounted on the back wall and at the other end to a link 52 which, in turn, is pivotally connected to the flywheel 48 by a pin 53 at a point outward of the center of the wheel and angularly displaced by a predetermined amount from the detent 49. The pin 53 is secured at a point radially inward from the detent 49, and the link 52 is offset awayfrom the flywheel 48 so that during a rotational cycle of the flywheel 48 when the pin 49 will pass the link 52, there will be no interference of the movement of the detent 49 by the link 52.

Prior to depressing of the button 42, when the flywheel is in its properly set position and ready for the next cycle of operation, the detent 49 will be engaged by an arresting means in the form of a lug or stop 54 of the manually actuatable lever 55. The lever 55 is pivotally mounted on a stud shaft 56 carried on the end of an offset portion 57 of a mounting plate 58 which is secured to the side wall 12 by fasteners 59. The offset portion 57 is such.

as to position the lug 54 of the lever 55 on the outer side of the flywheel 43 or on the side remote from the feed roller 31. A stop or limit pin 60 is spaced from the stub shaft 56 and also mounted on the olfset. portion 57 to be received within the confines of an arcuate slot 61 formed in the body of the lever 55 and in spaced relationship from the shaft 56. The lever 55 of course is appropriately apertured at 62 to pivotally receive the stub shaft 56. Thus, the pivotal movement of the lever 55 is restricted by the arcuate slot 61. The lever 55 is normally biased so that the stop 60 bears against the bottom half of the arcuate slot 61 by a spring 63 which is provided with coils arranged on the stub shaft 56 and with one end 64 anchored in a slot 65 of the lever 55 and the other end 66 hearing against a pin 67 mounted on the offset portion 57. In order to hold the springv 63. and the lever. 55 on the stub shaft, a spring retainer clip 68 engages a groove adjacent the outer end of the stub shaft andprovides a retaining means to bear against the outer side of the spring 63 which is placed on the stub shaft after the lever has been first placed thereon. To additionally hold the lever in mounted relationship with the mounting plate 58, and particularly with the offset portion 57, a washer 69 is arranged over the outer end of the stop 60 which bears against the outside of the lever 55 and is held thereon by a spring retaining clip 70 in a similar fashion as the spring retainer clip holds the spring 63 and lever on the stub shaft 56.

At the upper end of the lever 55 a plate 71 provides a bearing surface to be engaged by the inner end of the push-pull rod 43, whereupon depressing of the button 42 and the push-pull rod 43 shifts the lever 55 to the position as shown in Fig. 3, wherein the top of the arcuate slot 61 then engages the limit pin 60 and the lug 54 on the. lever 55 is removed from the path of the detent 49- on the flywheel 48 so that the force of the spring 50 pulls the flywheel 48 to the position shown in Fig. 3, which thereby issues a certain amount of toweling from the cabinet. Further issuance of toweling from the cabinet may be accomplished by merely grasping that portion of the toweling which has been issued by the rotation of the flywheel 48 by the spring 50 and pulling the toweling from the machine until the detent 49 again engages the lug 54 which will have assumed its original position as seen in Fig. 2 by the force of the spring 63, or by manual rotation of the presser roller 32 by spinning a control or ejecting wheel 72 which is mounted on the shaft- 33 ,of the presser roller 32 and arranged to have a portion of it projecting through an opening or slot 73. formed in the front wall 17 of the cover 16. This wheel 72 is peripherally roughened or formed with circumferentially spaced smoothly rounded lugs so that it may be easily operated by the hand of the user. Inasmuch as the presser roller is in tight friction engagement with the web of the toweling and the web of the toweling being between the presser roll and the feed roll 31, the toweling will be issued from the cabinet as well as the movement of the presser roll being transferred to the feed roll which will rotate in a clockwise direction as-seen in Figs. 2 and 3.

Inasmuch as the flywheel 48 will be rotating against the force of the spring 50 during further issuance of the toweling from the cabinet, means is provided to prevent reverse rotation of the flywheel which includes a pawl 74 pivotally mounted on a pin 75 of the lever 55 and engageable with the outer ratcheted surface or edge of the flywheel 48. The pawl 74 is gradually actuated to fall into engagement with the teeth on the flywheel 48 and prevent reverse rotation thereof at any time. In order to prevent rotation of the pawl 74 in a clockwise direction about its pivot end 75, a stop 76, Fig. 6, is secured to the pawl and engages the top edge of the lever 55, as seenin Fig. 2, and thereby prevents accidental rotation of the pawl to a non-operative position. If desired, a spring may be utilized in order to continually bias the pawl into engagement with the teeth on the ratchet wheel 48.

In order to further prevent dispensing more than the predetermined amount of toweling from the cabinet should the button 42 be held in a depressed position and the lug 54 be out of the path of the detent 49, an auxilary lug or stop is mounted on the lever 55, and generally indicated by the numeral 77 and which includes a main bar portion 78 spaced outwardly from the lever 55, Fig. 6, and a flange 79 extending inwardly from the free end of the bar portion 78 toward the lever 55. Thus, the stop 77 provides an open space through which the detent 49 may normally pass inasmuch as the bar portion 78 is spaced outwardly from the outer end of the detent 49 when the lever 55 is in its normal position as seen in Fig. 2. However, when the lever 55 is in its trip position as seen in Fig. 3,'the flange 79 is moved to a position which will block movement of the detent 49 as an attempt is made to rotate the flywheel 48 thereby. So only upon release of the lever 55 may the flywheel be moved past the auxiliary stop 77, and as the lever 55 is released to its normal position as shown in Fig. 3, the lug 54 is brought into operative position which will allow the detent 49 to bypass the auxiliary stop 77 and then engage the lug 54 on the lever 55. The machine will then be ready for a successive towel dispensing operation and as the flywheel 48 moves through a cycle of rotation, the link 52 and the spring 50 will move again to a position as seen in Fig. 2 whereby the detent 49 is biased against the lug 54 of the lever 55.

In loading the cabinet, the cover 16 is swung to its upper position as seen in Fig. 1 and a roll of toweling is placed on the inclined supports 30 so that the toweling may be drawn from the bottom of the roll and the toweling is brought between the feed and presser rolls 31 and 32 and slightly into the opening or delivery orifice 27.

For dispensing or issuing toweling from the cabinet, the knob 42 will be depressed to initiate one cycle of operation of the feeding mechanism whereby the detent 49 is disengaged from the lug 54 of the lever 55 and the flywheel 48 is allowed to rotate to the position as seen in Fig. 3 by means of the spring 50 and thereby issue a certain amount of toweling from the cabinet. By either grasping the end of the toweling and further pulling it from the cabinet or by rotating the ejecting wheel 72 to thereby feed the toweling from the cabinet, a predetermined amount of toweling may be supplied in accordance with the size of the feed roll 31; and during this feed operation, the feed roll 31 and the flywheel 48 will make one complete cycle or revolution until the detent 49 is again brought into engagement with the lug 54 on the lever 55.

It will be understood that modifications and variations may be eflected without departing fiom the scope of the novel concepts of the present invention, but it is understood that this application is to be limited only by the scope of the appended claims.
