This invention-relates to towel machines, and particularly to what are known asrnachines forj dispens ng roller towels and the object oi. the invention is top'rovide a machine towel receiving rollarelnounted to bear upon 1 rotatable drurns operatively coupled together whereby the rotation of one druin'will correspondingly' rotate the other, 7 the operative connection of said drurns being by a chain and sprocket construction the number oi teeth on the sprockets ofone drum being preferably greater thanthat ofthe other drum whereby the dimensions of extended towel loop may he naintained throughout the entire op- ,erati on of the machine; afurther object being to provide the front ofth e cabinet of the machine with two independent doors, the adjacent edges of which are spaced apart to permit of the passage of 'toweling'therebetween, one of said doors being provided with an internal catch and the other withja lock for securing said doors in closed position;'a

still further object bein'gto provide an auto} maticstop device for stopping the rotation of the drums and the feed of toweling in each revolution thereofl with means exposed through the cabinet for moving the stop into inoperative position to permit of entire rotation of said drums and the'feed of toweling, thus preventing the improper" withdrawal of toweling throughthemachine; a still fur,- ther objectbeing to provide means for preventing the withdrawal of toweling from the receiving roll and with these andother ob-. jects in view, the invention consists in a machine of the class and for the purpose'specified, which is simple in construction and operation, elficient in use, and which is "constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate .parts of our improvement are desig- 1011 an enlarged scale;

nated by suitable reference charactersin each i of the. views, and in which: 7

Fig. i is a'section on the line 1- 1 of Fig.3.

' Fig; 5 is a side view of the framework'of the machine, detached from the cabinet; and, Fig; G'isa sectional, sideview of the cabinet with the franiework removed, and showing the door in a partially open'position and in section. v I

ing side walls 10 andill, top wallf12, bottom wall 13, and a sheet inetalback wall 14,- the front ofthe "cabinet being open and adapted to be closed by doors 15 and 16 which are spaced apart'attheir. adjacent edges as seen In practice; we provide a cabinet comprisat 171 to permit thepassage of toweling18 therethrough. The lower door 16 is held in 7 position "by a catch device 19, engaging the side wall 11 ofthe cabinet, and the lower end of this: doorp rojects below the bottom 13 of the cabinet and is providedon its inner face withja roller 20. which extends beneath and in space'd relation to the bottom 13., and the ends ofthe" roller are conical inform as seen at 21 in iorderfto c'enter'the toweling- 18 on said roller in passing into the cabinet. An ironi'ng'board 22 is secured to the inner face of the door 16 and is positioned above the botminis ofthe cabinet and in front ofthe lower drum 23 mounted in the cabinet, the-upper drum being seen at 24. Thetoweling, in entering the cabinet, passes over the roller'2O through a recess 25 formed between the door 16 and the front edge of the-bottom 13 of the cabinet inwardly. and aroundv the edge of the ironing board'22 and then upwardly over the drum 23, and onto, the towel receiving roller 26, and this construction servesto properly straighten the toweling prior to its passage onto the receiving roll. a I I The upper door 15' of the cabinet is held in closed positionby a locl -mechani'sm indi-- means? in Fig. 1- of the'drawing', and this door is also preferably provided with. a

mirror 28 to add tothe appearance thereof,

and to render further service.

Secured to the inner face of the side walls 10 and 11 are frames 29 and 30, and each frame is provided at its upper end with L- shaped apertures 31 of the general form seen in Fig. 2 of the drawing, which open out-- wardly through the front edge of the separate frames to permit of the passage of the towel delivery roll 32 into said apertures, and particularly the vertical portions 31 thereof, as seen in said figure. The apertures 31 are offset as seen at 31 to prevent the accidental displacement of the delivery roll, should the same be subjected to sudden stress, especially in pulling downwardly upon the towelingat one side thereof and with one hand, the projecting tongues .31 operating as stops to prevent this displacement. At the lower end portion of the frames 29.3O are other L-shaped apertures 33 in which the towel receiving roll 26 is mounted. These apertures are of the general construction of the apertures 31 but are not provided with the projecting tongues 31.

The drums 23 and 24 are mounted in the frames 29 and in order that said drums together with the mechanisrnfor actuating the same may be removed from the casing as a unit. Adjacent the frame 29 and'outwardly thereof with reference to the wall of said frame. the drums 23 and 24 are provided with sprockets 23 and 24 around which a chain 34 passes. It is preferred that thesprocket 23 be of slightly less diameter and provided with one tooth less than the sprocket 24 in order to compensate for the comparatively loose winding on the receiving roll 26 land the different nature of the fabric by being subjected to moisture; the object being to maintain a towel loop 18 of substantially the same dimensions projecting from the casing at all times, and especiallypreventing the enlargement of such loop, which has beena difiiculty in apparatus of this class. a In order to aid in supporting the frames 29 and 30 in spaced relation, a coupling rod 35 is employed.

Adjacent the frame 30, the drum 24 isprovided with a cam or eccentric disk 36 secured to the projecting trunnion 37 of said drum, and the outer face of the cam is provided with a plurality of notches 38 in connection with which a gravity pawl 39 pivoted to the frame 30 as seen at 40, operates, to prevent backward movement of said vdrums in the event that it be endeavored to withdraw the toweling 18vfrom the receiving roll 26.

The inner side face ofthe cam 30 is provided with a projecting, arc shaped lug 41 which is adapted to cooperate with a stop bar 42 supported in abearing block43 mount-- ed in connection with the frame 30 and in which the stop. bar 42 is slidably mounted, the bar being provided at its inner end with a recess 44 through which the lug 41 is adapted to pass when the bar 42 is in its innermost position, which is limited by the hub portion 36 of the cam 36. The bar 42 is provided outwardly of the recess 44 with a projecting,

pin 45 adapted to operate in connection with the periphery ofthe cam 36 whereby in the rotation of said cam by the drum 24, in the direction of the 'arroww, Fig. 3, the pin 45.

together with the bar-42 is advanced outwardly or forwardly by said cam, this operation taking place after the lug 41 has passed through the recess 44 as seen in said figure. When the bar 42 has been advanced as above stated, and on the completion of the revolution of the drum 24, the lug 41 will strike the inner end 42 of the bar, and stop the rotation of such drum until such time as the bar 42 has been moved inwardly in the position seen in full lines in Fig. 3. This result is accomplished bya'push button 46 mounted inv the door 15 of the cabinet in alinement bar 42 inwardly, all that is necessary is to press thepush button 46 inwardly. The inner end of the push button is provided with an enlarged head 47, which, together with the head at; the outer end of the push button, prevents the displacement thereof from the door 15 when the same isswung outwardly.

In Figs. 5 and 6 of the drawing, we have shown the framework including the operative mechanisms of our improved machine, removed from the cabinet as aunit, the framework and mechanismsbeing shownin Fig. 5

and the cabinet with said framework removed, in Fig. 6.. By virtue of thisconstruiction,'the cleaning and repair ofthe operative mechanisms of the machine may be readily accomplished without marring or destroying V the cabinet proper inanymanner, and this will also facilitate the replacement of parts of the mechanism, if the same should be desired. It will also be understood that a new frame including new mechanisms may be substituted for an. old one, and the old one shipped to the factoryor repair shop for rebuilding or other purposes, if the same should be found to be necessary at any time.

From the foregoing, it will be apparent that after each downward pull on'the toweling 18, the furtherwithdrawal ofthe toweling is stopped until such time as the push button 46 is moved inwardly, thus preventing improper use of the'toweling or abuse to position, as seen in Fig. 2 of the drawing, the.

receiving roll 26 being first placed in position and the door 16 closed, after which the de livery roll 32 is placed in position and the door closed after the required loop eXtenstructural details herein set out and various changes therein and modifications thereof may be made within the scope of the appended claims, without departing from the spirit of our invention or sacrificingits advantages.
