web and to simultaneously-winder to{ take up,

the soiled towelinga'fteruse; and iSfa f divisional partof my' prior application for patent on' Towel cabinets, SerialNo: 376,575;'filed"January,30;

Anobject of the invention is to.-provid'e means t'orcont'rolthe'feedihgof" the towel so. that in pulling alength. of. tow'eling the feeding. or

measuring roll is .turned' other than an integral number of revolutions, thereby; assuring more than one stopping positionlso that the pinch r011 will not engage the abrasive surf ace of the feeding roll at the same point after each feeding, operation,- thereby distributing the wear over. the entire friction or abrasivesurfaceof the rolland insuring'a longer useful 'lifeior saidsurface andv positivelyfeeding the towel and winding or taking up the soiled to-welz;

Another object of vtl'ieinvention is. toprovide' a" novel ratio of feeding,. winding timing" and.

7 time release mechanism Whereby1 the friction feeding and winding rollers are advanced other than one complete revolution each time al'ength, of towelingis-pulled down' or out for use so as.

to causethestrino'fttoweling :to engage different points on the ,surfacesof the feeding andgwind'a ingrollers for every one of a multiple of'operations'or revolutions thereof; such as thereby, preventing unclue'wear' at" particular points on;

the friction surfaces of'said rollersv and increas ing theuseful life of'saidi'rollersurfaces a multipic; i;- e.; five-times'their'ordinaryjlife.

Another object of the invention is to so arrange and support" the towelingwithin' ,the' cabinet that practical maximum of contact areas or lengthsof'.

the toweling" will: be. engaged with practical-f maximum of frictional contact areas tori periphiq eral surfacesofthe feeding and winding or takeup rollers to'also insure longer useful livesfor said surfacesandmo-re positive, uniform and even. feeding and winding of the-towe'ling;

Another'an'd'important object of the invention is to 'provide a pinch roll which is contained in an assembly serving as a toweling guide and made separatefrom the rest of'the mechanism thereby permitting the positioning of"the',-pinch" ro11 after the toweling-has been placed in position and" the clean toweling roll thrown in"- so as'to make threadihgof "the toweling unnecessary.

Another object of the invention is to' place the pinch r011 undersp'ring tension'so that no towel slippageis required to'set the' pinch roller firmly as compared with other'machines'which require motion of'the toweling' to accomplishthis fl1nC tion.

Another object of the invention isft o hold'the soiled towel 'roll in contact'with thewinding or take-up roller'by spring'tension instead- 'of depending upon gravity as in other machines sons to accommodate a wide yari'ance in roll size and produce a more uniformly and tightly wound roller of soiled toweling, thus reducing the space requirement'of the 'roll'.

Another object of the invention is to provide novel means for supporting and feeding a clean toweling as well as windingup a soiledtoweling including a 'novelconstruction of rollers for maintaining the toweling' undertension and insuring uniform, even and positive ,feeding and winding; ofthe to-welingand which, in addition to the above stated object. of permitting the removal of the mechanism supporting frame, to permit quick and convenientremoval and replacement oftthe friction rollers, or cylinders ,of'the feeding, and" winding, rollers-at the placeof installation or use when .the friction surfaces thereofhave-tbecome wornwithout the necessity ofitakingflthe entire. cabinet back .to.the shop'or factory.

Fig. 6 is an end elevation timing mechanism and gearing on the lower friction or sand feeding roller, and

Fig. 7 is a detail section of one end of a friction roller.

Referring more particularly to the drawings in .detail, [5 designates a vertical support such as a wall, board or plate mounted against or in a wall designed to support the cabinet thus obviating the necessity of employing a floor stand so that valuable floor space may be otherwise used. Secured to the vertical support I5 is a back mounting plate l6 preferably of metal having right angular or outstanding vertical or parallel side flanges I! designed to removably support the frame or mechanism of the device. As shown, these side flanges are provided with a plurality of bayonet slots 18 opening at the top through the edges of the flanges to receive outstanding pins l9 projecting from the side plates 20 and 2| of the frame of the machine which supports the mechanism as a unit. If desired, three of such pins and bayonet slots may be provided, the pins l9 engaging the upper and lower slots and the intermediate slots being engaged by clamping screws 22 engaging threaded apertures in the plates 20 and 2| instead of providing pins H! to engage the slots, so as to hold the frame from vertical displacement but permit removal thereof should occasion arise. The frame also includes upper and lower spacing and connecting or tie rods 23 and 24 having reduced ends forming shoulders to engage the inner faces of the side plates 20 and 2| so as to rigidly hold the same in uniform spaced relation parallel to each other with screws anchoring the ends of the rods at the outsides of the plates. The bottom edges of the plates 20 and 2! are provided with apertured ears 25 near their inner and lower corners and the cabinet or housing 26 which is shown as being substantially of rectangular form and open at the back is provided with a bottom opening 21 flanged inwardly around the bottom edge. While the cabinet may be pivoted or hinged to the mechanism or frame near the lower rear corner of the machine to enable it to swing forwardly and downwardly to serve as a container for holding the clean towel roll, towel guide, soiled towel roll or any other articles which might otherwise be mislaid .or difficult to manipulate during the loading of the machine. In the form shown, the bottom flanges or sides of the cabinet are shown provided with inwardly extending pivot pins 28 projecting in to engage the apertures of the pivot ears or lugs 25. The cabinet is sufficiently resilient to permit the sides to be separated so that the pins will spring into the apertures when the spreading pressure is released. Thus, the cabinet may be swung down beneath the frame with its open side upwardly so as to conveniently receive and retain as well as render accessible any parts placed therein. When closed, it is swung upwardly and may be held locked by any suitable means to prevent access to the interior of the cabinet. As shown, a looking screw 29 is provided in the top wall of the cabinet adjacent the open side and edge thereof which may be operated by a socket or plug wrench to engage the keeper or aperture of an angle bracket 30 secured to the mounting plate Hi. If desired, a mirror 3| may be provided at the front of the cabinet and held at the back by a removable plate 32 over an opening in the front of the cabinet with suitable interposed cushion packing to prevent breakage of the mirror.

A bottom plate 33 is provided for the cabinet but is supported between the side plates 20 and 2| of the frame and this bottom also serves as a separator between the clean toweling roll and the ascending soiled toweling and can be swung clear of the back of the machine or back mounting plate IE to provide ready access thereto for simplifying the task of loading as will be hereinafter more fully explained. The front edge of the bottom plate 33 is shown rolled or curled up as at 34 spaced from the front wall or bottom of the front portion of the cabinet and at the back or rear corner is curved upwardly as indicated at 35 over the lower rod 24 to receive and support the clean towel roll when the same becomes small. This plate is then extended vertically as at 36 to form a separator or vertical partition in spaced parallel relation to the back mounting plate I6 and provide a narrow transverse vertical channel 38 therebetween through which the soiled or used towel may be passed to the winding or take-up roller, as will be later described and prevent contact thereof with the clean toweling. The top edge of the vertical plate portion 36 is provided with an angular portion 31 directed forwardly and then upwardly to frictionally spring or resiliently set under and against the upper rod 24 to hold the plate in position at the back of the frame in front of the channel or space 38. The bottom 33 is pivoted between the side plates 20 and 2! preferably in spaced relation to the rolled front edge 3% and for this purpose, may have angular brackets of L-shaped form rigidly secured thereto at the top by riveting or otherwise and provided with outwardly extending pivot lugs 39a extending through correspondingly located apertures in the side plates 20 and 2!. In this manner, the bottom plate together with the partition may be swung on the pivots so that the curled end 34- swings downwardly and rearwardly, the bottom portion 33 upwardly, and the vertical portion 36 upwardly forwardly and downwardly so as to expose the back of the cabinet or frame when the clean towel roll is not in position.

The feeding roller is designated at F and is journaled between the plates 29 and 2! near the lower forward corners thereof and the corresponding portion of the frame, this roller being a friction or sand roll to insure gripping of the toweling T and the same as the winding roller forms a portion of the mechanism for the winding of the soiled. toweling when the towelin is pulled out as will be later explained. The winding or take-up roll is designated at W and the clean towel in rolled form is designated at C, while the soiled towel roll is designated at S. An idle roller I is positioned beneath the clean towel roll C parallel to and slightly spaced rearwardly from the feeding roller F so as to take the weight of the clean towel roll when the latter is initially put into the machine to rest on the idle roller and against the vertical portion 36 of the plate where it forms a separator or partition where the soiled towel passes upwardly in contherefrom to extend between the plate and a housing I9 of angular flanged construction secured to the outer faces of the plates 20 and 2! and each having a slot 80 through which said finger piece operates. Lugs 8| are provided on the side plates spaced from the lower ends of the guideways of housings I9.

The feeding and winding or take-up rollers F and W constituting the friction or sand rollers are substantially alike in construction and each comprises a tubular cylinder or tube 82 of metal or other suitable material and provided with aligned longitudinal slots 83 near each end through which the tapered ends 84 of a spirally wound emery or sand paper strip 85 are bent, inserted and anchored, the strip being suitably anchored or glued to the cylinder if desired. The ends of the cylinder are provided with spaced segmental notches 86 equidistantly spaced apart and preferably three in number forming corresponding intermediate projections 81. Disks 88 forming webs fit the notched ends of the cylinder or body and for this purpose are provided with spaced projections 89 to enter the notches 86 and corresponding notches 90 to receive the projections 81 to reinforce and close the ends of the tubes as well as connect the cylinder and disks to cause them to rotate together. The disks or webs fit snugly in the ends of the cylinders and are provided with outwardly projecting tubular flanges or hubs 9| forming spacing means between the disks and the frame members 20 and 2| and receiving shouldered tubular trun-,

nions 92 which are keyed to the disks and the hubs to turn therewith. The tubular trunnions 92 are provided with twolopposite flattened surfaces 93 at their outer portions and a peripheral groove 94 circumscribing the same and intersecting the flattened portions. Flanged bearings 95 are mounted on the trunnions 92 and have their flanges positioned within and against the inner face of the plate 20 adjacent the hub 9I at one side of the frame. At the opposite side a separate or removable bearing plate 96 is bolted to the plate IN and has a sleeve or hub 9'! extending into an opening 98 of larger diameter than the hub 9! as seen in Fig. 2. Screws 99 secure the plate 96 in position and a tie rod I extends through the roller and the tubular trunnions or bearings 92 and have their threaded ends anchored as by nuts IOI engaging threaded ends of the tie rod thus to hold the parts in assembled relation and against end thrust by engagement with the ends of the tubular trunnions or bearings 92. At one side of the frame, sprockets I02 are mounted on the flattened portions 93 of the trunnions and fixed by a set screw I03 while an endless drive member or chain I04 is trained around the sprocket wheels to cause the friction rollers to rotate in unison. They are held in position by spring cotter pins I 05 which engage the annular grooves 94 at one end, preferably the" right side of the machine although this is optional. The corresponding end of the winding roller W is provided with a ratchet wheel I06 on the flattened portion of the trunnion 92 with its hub or collar between the plate 96 and the hub or collar of the sprocket wheel I02 (see Fig. 5). At the bottom roll F, there is no ratchet Wheel but the collar is retained (see Fig. 7). The teeth I01 of the ratchet wheel I06 are engaged by a pawl I08 pivoted at I09 to a boss on the plate 2I and held by a spring IIO into engagement with the teeth I01 so as to prevent backward or retrograde movement of the winding roller so that the soiled towel cannot be unwound from the soiled towel roller and so that the parts can only be driven in one directiontending to feed the clean toweling and wind the soiled toweling. A collar I061; is mounted to take up space on the trunnion 92 of roller F at the bottom in lieu of the ratchet wheel I 06 as provided on the roller W at the top where the ratchet wheel I06 and pawl I08 are provided to prevent reverse rotation, and to avoid end thrust. However, this construction permits quick removal and replacing of a friction roller by simply removing the nuts IOI rods I00 and drive parts by removingthe screws 99 of the plates 96 so that the hubs 9| at one side can be displaced through the corresponding openings 98 and the webs or disks set in the ends of the body 82 displaced outwardly so that the body or cylinder can be removed and a new one inserted and secured in position. Thus, the notched construction of the friction or sand rolls where the disks or webs set into the ends of the body or cylinder of the roll nables replacement of the worn friction or sand surface by substitution of the body only by reason of the separate bearing plates at the right hand or side plate 2I and the entire removal and substitution can be eil'ected without disassembling the machine. The tie rod construction of the assembly converts any transverse load on the sand roll hubs into a lineal stress on the tie rod and not on the web assembly alone.

Thus, if under extreme abuse something must give way, the resulting deformity will only be the stripping of the threads on the tie rod by failure of the cylinder and its sprocket wheel to turn together because the nuts IOI are jammed against the bearing sleeves on trunnions 92 at the threads. Thus, the hubs will be slightly loose on the trunnions 92 but not broken and the machine will not be out of service. The cost of this common type repair is reduced to just a fraction of the usual cost or entirely eliminated by this construction.

The control mechanism of the machine for the feeding, winding, timing and time release mechanism is preferably mounted at the left hand end of the lower friction or feeding roller adjacent the plate 20 at the outside and for this purpose a spur gear or pinion I II is mounted on the flattened portions 93 of the trunnion 92 and is held in position by a spring cotter pin II2 engaging the annular groove 94 adjacent the flanged bearing at that side. 'The gear III is also held by keys II3 fitting the flattened portions 93 and registering recesses in the gear as shown in Figs. 2 and 6. A gear I I I is driven by the gear II I and operates checking and releasing mechanism adapted to be controlled by a timing mechanism H5 as shown and described in my copending application Serial No. 376,575, filed January 30, 1941.

Operation rotate by the pawl I08 riding over the teeth of the ratchet wheel I06 but restraining the same I the rollers and the manner in which the toweling is run through the machine as well as the rollers for feeding and winding up the toweling and the arrangement of the pinch roller P and the soiled towel roller S held under constant spring pressure against the respective feeding and winding rollers F and W respectively insures uniform, even and positive feeding and winding of the toweling as it moves down at the front and up at the back. This is also due to the fact that the soiled toweling roll is held in contact with the take-up or winding roll by spring tension instead of depending upon gravity as in most, if not all other machines, thus not only producing a more uniformly and tightly wound roll of soiled towel but also reducing the space requirement of the roll. .The pinch roll is also contained in an assembly or frame which serves as a toweling guide by reason of the opposite edges of the toweling strip feeding between the end plates 4| thereof. and between the feeding roll and the guide plate 43 which is disposed in spaced concentric or parallel relation thereto. By having the pinch roll assembly separable from the rest of the mechanism, the pinch roll may be placed in position after the toweling has been mounted in position, thus making threading of the toweling between rollers I, P and F unnecessary, placing of the toweling is also facilitated especially due to the fact that the separator or partition formed by the vertical wall 36 may be swung away from the back of the machine when the end of the toweling is first wound upon the soiled towel roller.

feeding roll under spring tension and positioned or snapped in position under such tension over the feeding roller and under the clean towel roll so that the toweling is looped down between the idle roller I and the feeding roller F by the pinch roller P when in position as more particularly shown in Fig. l of the drawings, no towel slippage is. required to set the pinch roller firmly. The toweling is maintained in constant uniform contact under pressure with a maximum surface of the feeding roller as well as the idling roller. This is also true in respect to the engagement of the toweling with the winding roller W over more than one-half the circumference thereof and is further insured by the pressure between the toweling on the soiled towel roller S and the periphery of the winding roller W due to the resilient mounting of the soiled towel roller and the action of the springs 16 in maintaining the roller S and the soiled toweling wound thereon against the surface of the roller W by means of the spring held bearings 10. The separators 36 and 63 also maintain the clean toweling out of contact with the soiled toweling and the latter separator compensates for the varying sizes of towel roll and when the clean towel roll is sufil ciently small, it may drop between the idle-roller I and the vertical plate 36 on to the bottom 33 while still pressing against the idle roller I and increasing the surface contact with the latter until entirely unwound and paid out. At this time the bearings 10 may be depressed and the soiled towel roll displaced and removed by disengaging the trunnions 68 from the bearings ID at the open recesses 69, when the machine is again in condition for reloading in the manner previously described. It should also be noted and will be apparent from the foregoing description of the construction and operation that due to the feeding and winding rollers being of the same diameter operatively connected as described and directly controlling the feeding and winding thereof as well as the regulating and timing mechanism and intervals when the device is locked, in addition to .the means for preventing retrograde movement or unwinding of the soiled toweling roll, the soiled toweling will be rolled up into the cabinet in the form of a roller at a linear rate exactly equal to the linear rate at which the clean toweling is uniformly dispensed Or pulled out according to the adjustment for which the machine is set but preferably approximately eight inches, thus keeping the amount or length of the depending loop of exposed toweling substantially constant. of toweling dispensed at each use is preferably eight inches, this may be adjusted 0r varied as desired, as by varying the sizes of the feeding and winding rollers and the gear ratio of the driving means or gearing train, so that each successive length of toweling dispensed shall be and remain uniform once an adjustment is made. Also, the operating parts, device or feed roller and the toweling are locked against movement after each pulling of the towel and the toweling prevented from slipping when pulled unnaturally hard or in normal operation, thereby preventing rewinding of the used or soiled toweling on theclean toweling roll or unwinding the used or soiled toweling from the soiled toweling roll. Also the time interval between feedings may be controlled by the time controlled mechanism which may be adjusted as desired, say from five to twenty-two seconds or otherwise The time controlled mechanism as Well as all the other mechanisms are not accessible to any one using the machine by reason of being enclosed in the cabinet in the manner described thus, preventing tampering therewith and rendering the device fool-proof.

It may also be stated that by having the damp used toweling pass upwardly against the lower tie rod 24 and the separator or plate 36 under angular stress at the top and bottom, the damp toweling is smoothed flat instead of leaving the same folded, rumpled or uneven and free to shrink. This is assisted by placing the toweling under pressure and tension of the depending loop and pulling thereon in dispensing or pulling the toweling out or down and in use, and in being wound or taken up on the roller W and the roll S, as well as the frictional engagement and sliding against the rear lower truss rod 22 and the plate 36 whereby the toweling will be kept smooth and somewhat stretched out to normal condition or length and assisted in drying, so that the depending loop or length of toweling for use will be maintained in a loop of constant length, instead of shortening by drying in a crinkled, wrinkled, folded or uneven condition. y

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this iscapable of variation and It will also appear that while length modification? withoutidepamtingfromthe, spirit of thei inventiom I, therefore-,; do not wish to be limited-to the precise'details; of construction set forth,

but desire to avail myself of such variationand modification as come within the scope of the appended. claims. l s
