FEED CONTROL DEVICE FOR TOWEL CABINETS Filed Dec. 25, 1929 I 2 Sheets-Sheet 2 fnvenfor Pie/a N11 6. 5TE/NEB ATT'GENEYJ part of this specification Patented Apr. 12, 1932 y-UNITED STATES PATENT-TOFFEE OF SALT LAKE CITY, UTAH, A CORPORATION OF 'UTAH FEED coNTEoL DEVICE FOR rowEL cA'B'INErs Application filed December 28, 1929. Serial No. 416,038.

In towel dispensing cabinets where a feeding instrumentality is provided for delivering the clean web of towel to the-user and a take-up device is arranged to wind up the soiled portion of the towel within the cabinet, it is desirable to provide a lock device'which when moved to its release position, will permit the delivery of a predetermined len 11 of towel during the period or time t at elapses between the release ofthe feeding instrumentality and the relocking of the same, and it is further desirable to'provide means to prevent the effective operation of the release mechanism until a certain time has elapsed after the delivery of the towel has begun.

The particular object of this invention is to provide a time control mechanism adapted for use with a cabinet such as shown in my Patent #1,724,229, issued August 13, 1929, as an improvement on or substitute for the dash pot and plunger mechanism shown and described in this patent.

Other objects of the invention will appear from-the following detailed description.

, The invention consists generally of various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

' In the accompanying drawings forming a Figure' 1 is a vertical sectional view through a towel dispensing cabinet embodying my invention; v

Figure 2 is a detail sectionalviewshowing the particular arrangement of the time con trol device in its normal position;

Figure 3 is a similar View showing the slide connected with the time device raised to a point where it prevents the operation of the release mechanism;

Figure 4; is an edge view showing the connection of the slidewith the feeding instrumentality;

Figure 5 is an outside view with the wall of the casing partially broken away, looking toward the end of the feeding instrumentality and showing the release mechanism in its normal position.

In the drawings, 2 represents a suitable cabinet having a top 3, a rear wall 4, a bottom wall 5 and a suitable front door 6 that is adapted to be opened to expose the inside of the cabinet. 7 represents the inner section of the cabinet adaptedto swing outwardly on pivots 8, but as this features forms no part of the present invention I do not need to describe the manner of such movement. '9 is a feed-roll having a roughened peripheral surface. '10 is a similar take-up roll having a driving connection with the feed roll for simultaneous movement. 11 represents a supply of'clean towelresting upon a suitable support 12 within the inner section, the looseend of the towel web being carried up between the feed roll 9 and the door 6 and around a pinch roll 13 that is loosely mounted in guide slots 14 in the side walls of the inner casing.

The relative position of the rolls 9 and 13 is such that when a downward pullLis exerted by the user on the towel web which depends through the opening in the bottom of the cabinet, as plainly shown inFigure' 1, the roll 13 will be drawn downwardly to press the towel web against the roll 9 with suflicient friction so that this roll will be driven and simultaneously a corresponding movement will be imparted tothe'roll 10. Atake up roll 15 is mounted in guide slots 16 and the web of soiled towel is passed'c-up- FRANK G; STEINER, OF CHICAGO, ILLINOIS, ASSIG-NOR TO STEINER SALES COMPANY,

wardly through the bottom of the cabinet between the wall 12 and the rear of the cabinet and in contact with a pressure device 17 which cooperates with the edge of the wall 12 to-smooth and st'raightenthe towel web and exert the desired degree'of tension thereon so that the convolutions of the web on the roll 15 will be drawn against the roll 10 with suflicient pressure to cause the continuous revolution of the roll 15 and the windingup of the soiled towel when the rolls 9' and 10 are operated. All this structure is shown and described in my former patent above referred to and is herein illustrated merely to make clear the use of the cabinet. w

The feed roll 9 has a bore 18 therein adapted to receive a locking bolt 19 that is free to 20 and the pin 21. This bolt is free to slide by gravity and normally its outer end isadapted to enter a slot 22 provided in the bracket 23 and engage a stop 2d at the upper end of the slot and thereby lock the feed roll against revolution. The bracket has a guideway 25 ;adap'ted to receive a slide 26 and the wall of the guideway has an opening 27 opposite the slot 22 in position to permit the end 28 of a pivoted arm' 29 "to be thrust through the opening 27 and contact with the end of the bolt 19 to disengage it from the stop 24K. This operation of the arm '29 may be effected by means of a spring member 30 secured preferably to the door of the cabinet and having a cap 31 which projects outwardly in position .to be pressed by the user of the towel for the purpose of initially releasing the feed roll. A cam 32 is mounted on the end of the feed roll?) and provided with a shoulder 33 in position to engage'a lug 34 on the upper portion of the slide 26, whereby when the feed roll is released upon the initial. movement of'the bolt 19, its revolution will engage the shoulder 33 with thelur 3i and. raise the slide to the position indicated in Figure .3, where it will be held positively until such time as the shoulder 33 passes out of engagement with the lug 34. When this occurs, the slide would naturally drop by gravity to its normal position and allow the second operation of the .arm 29 and for the purpose of timing the downward movement of this slide and rendering the release arm again efl'ective, I connect a mechanism with the slide which I will now describe in detail.

A-suitable plate 35 is mounted in the casing and adapted to support a train of gears. A pinion 36 is mounted on a gear wheel 37 and meshes with the teeth of the gear wheel 38.. The gear wheel 37 meshes with the corresp nding pinion 39 that is concentric with a gear 40. An escapement lever il engages the teeth of the gear wheel 40 and is provided with a balance wh-eel 42. An arm 43 is pivoted concentric with the axis of the gear 38 at one end and has its opposite end pivotally connected with the slide 26 by a rod 44. A dog 45 is pivoted on the arm 42 and is normally held by a spring 46 in engagement with the teeth of the gear 38 and a spring 47' is connected with the arm 43 and is adapted to normally exert a downward pressure on said arm that will tend to turn the gear wheels and operate the escapement lever 41, the ar 'rangement being such that when the arm 43 is raised with the slide to the position shown in Figure 3, the pressure of the spring exerting a downward force thereon, and aided by gravity of'thearm 43 will turn the gear 38 and through the other gears and pinions, rock the escapement lever 41 and allow the mechanism to operate with a step by step move- -ment which will "continue until thearm and 7 the slide reach their normal position as indicated in Figure 2, and in such position these parts will remain until the slide is again operated and raised to a point where it will prevent the release arm from disengaging the locking bolt from its stop.

Thea-wheel, 42 secured to the shaft of the escapement lever operates through its weight to retard the movement or oscillations of the escapement lever. This takes the place of the ordinary small 'tortion spring that is usually used with an escapement lever. Evidently this escapement mechanism may be so constructed that the time of the travel of the arm from its raised to its down position can be increased or decreased according to the desired period of time during which the user is to be prevented from manipulating the release lever.

"This escapement mechanism iscomparative'ly inexpensive to manufacture and is extremely efiicient and reliable in operation. It

eliminates the use of liquid in a dash pot and the tendency of such liquid to escape from the dash pot cylinder. The escapement can be easily and quickly applied to a cabinet and being of extremely simple construction, will add but little to the initial cost. Whenever desirechthe rod it maybe disconnected and the slide used independently of the timing mechanism, in which case it will drop by gravity to its normal position as soon as permitted to do so the operating. cam.

In various Ways the details ofconstr-uction herein shown may be modified, such as in the form shown in the' escapement, and-the manner of connecting it to the reciprocating slide, and still be within the scope of my invention.

I claim as my invention:

In a control mechanism for a towel cabinet feed releasing device, an escapement mechamsm, a'pivoted arm and means to bias said armto move in one direction, a dog on said In witness whereof,l have hereuntoset my hand this 18th day of December, 1929.
