Fig. 8 is a fragmentary detail sectional elevation of one end of a friction roller.

Fig. 9 is an enlarged vertical sectional elevation of the upper portion of the cabinet immediately within one side thereof.

Fig. 10 is a sectional view taken on the line Iii-Ill of Fig, 9, and

Fig. 11 is a sectional view taken on the line II-II of Fig.- 10.

Referring more particularly to the drawings in detail, I5 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 I6 preferably of metal having right angular or outstanding vertical or parallel side flanges I 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 I8 opening at the top through the edges of the flanges to receive outstanding pins I9 projectin from the side plates 2!] and 2I 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 I9 engaging the upper and lower slots and the intermediate slots being engaged by clamping screws 22 engaging threaded apertures in the plates 29 and 2| instead of providing pins I9 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 havin reduced ends forming shoulders to engage the inner faces of the side plates and 2I 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 26 and 2I 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 mlislaid or difiicult 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 locking 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 or key to engage the keeper or aperture of an angle bracket 30' secured to the mounting plate I6. 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 pre-- vent breakage of the mirror.

A bottom plate 33 is provided for the cabinet but is supported between the side plates 29 and 2 I 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 I6 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 edge 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 passage 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. 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 passage or space 38. The bottom 33 is pivoted between the side plates 20 and 2I preferably in spaced relation to the rolled front edge 34 and for this purpose, may have angular brackets 39 of L-shaped form rigidly secured thereto at the top by riveting or otherwise and provided with outwardly extending pivot lugs 39a extendin through correspondingly located apertures in the side plates 20 and 2!. Because of this structure, the bottom plate together with the partition may be swung on the pivots so that the curled end 34 swings downwardly and rear-wardly, the bottom portion 33 upwardly, and the vertical portion 36 upwardly, downwardly and forwardly so as to ex- The top edge of the vertical zpe zsaea pose/\theabacksot thercabineiaor framecwhen the clearntowel I'QH"ifiSr-IIQtwiHrQOSitiQH.

This plate is pivoted' at the freeinn'er en'ds'of a pair 5 of opposed arms 65 closely adjacenttheinner faces 'of the"si'deplats 20 an'd' 2l, these arms beingpivoted as at 66"to' saidplates with screws 61 for removablymounting the arms and plate in "positions The soiled towel roller- S-has reducedtrunnio'ns 68 ournaled' in open bearings or re'ces'ses 69 m #the' -upp'er: "ends of the'; bearings or bars' 'l'fl which have "spaced-flanged collar'sfi l adapted to slide in elongated forwardly inclined slots I2 in the side plates 20 and 2I These bearings or bars "I are retained in position by strips or slides 13 mounted on the reduced ends .of the flanged collars II and held by clamping screws 14. The slides I3 have outstanding angular or bent ends I5 to each of which a coiled spring I0 is anchored at one end and at the opposite end by means of screws or the like to the plates 20 and 2I of the frame as indicated at 11 so as to normally exert upward tension to press the soiled towel roller S toward the winding or takeup roller W. Each slide 13 is provided with a finger piece l8 bent therefrom 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 8I are provided on the side plates spaced from the lower ends of the guide ways or housings 19.

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 3e equidistantly spaced apart and preferably three in number forming corresponding intermediate projections 07. Disks 88 forming webs or beads fit the notched ends of the cylinder or body and for this purpose are provided with spaced projections 89 to enter the notches 80 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 pro jecting tubular flanges or hubs 9I forming spacing means between the disks and the frame members 20 and 2i and receiving shouldered tubular trunnions 92 which are keyed to the disks 88 and the hubs 9 I, to turn therewith. The tubular trunnions 92 are provided with two opposite flattened surfaces 93 at their outer portions anda peripheral groove 94 circumscribing the same and intersecting the flattened portions. Flanged bearings 9-5 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 2| and has a sleeve or hub 9'! extending into an opening 98 of larger diameter than the hub 9I as seen in Fig. '2. Screws 99 secure the plate 98 in position and a tie rod I00 extends through the roller and the tubular trun-' nions 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 I05 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 trunnions 92 with its hub or collar between the plate 96 and the hub or collar of the sprocket wheel I02 At the bottom roll F there is no ratchet wheel but the collar is retained (see Fig. 4). 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 direction tending to feed the clean toweling and wind the soiled toweling. The ratchet wheel I06 has a spacing sleeve or hub I06a extending to the plate 96. A collar IBM is mounted to take up space'on the trunnion 92 of roller F at the bottom in lieu of the ratchet wheel I06 and its sleeve or hub I06a as previously described. However, this construction permits quick removal and replacing of a friction roller by simply removing the nuts IOI, rods I00 and drive parts by removing the 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 82 where the disks or webs 83 set into the ends of the body or cylinder of the roll forms axially displaceable connections between the ends of the cylinders 82 and the disks or webs 88 which enables replacement of the worn friction or sand surface by substitution of the body only with another body having a new friction or sand surface thereon, by reason of the separate bearing plates 96 at the right hand or side plate 2| and the entire removal and substitution can be effected without disassembling the machine. The tie rod construction of the assembly converts any transverse lo-ad 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 red by failure of the cylinder and its sprocket wheel to turn together because the nuts IOI are jammed against the bearing sleeves or 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 I I is mounted on the fiattened portions 93 of the trunnion 92 and is held in position by a spring cotter pin I I2 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 Fig. 2. A gear II4 meshes with the gear I I I and cooperates with other gears to intermittently check the advanc of the towel feeding roller F and the timed release thereof as fully shown and described in my prior application, Serial No. 376,575, above referred to and of aee'rgeoa necessity- 015'threading'the toweling web or-strip so which this application is a continuation part. In the modified form shown in Figs. 6- and 7-; the construction is the same as previously described-except that the lower tie rod- 24a is set" back slightly" to receive the toweling web; or strip in front thereof instead-"offir'r back as in the other tion 31a extending upwardly and over the upper tie rod 24-1) on' and over which the towel rides under portion 31a. Portion 31a is then bent rearwardly at its upper end, preferablysubstantially horizontal-1y or'slightl'yinclined downwardly as at 3Tb toreceive the towel thereagainst at its} rear edge which is folded or bent. over or'turned' back that is', upwardly and forwardly over the top as. at S'Ic'to cause the toweling' to scrape or slide thereon and stretch and smooth the toweling toremove wrinkles and maintain the normal lengtlrso that the depending loop Willremain at a constant length and be tightly wound up on the'soiledtoweliroll S. this instance theto'weling is extended-directly to the roller S over and on the rounded portion 31a and is engaged by the friction winding or take-up roller W against the roller S to wind the toweling on the latter as" the clean toweling is'pulled or dispensed from the. rollerF. This arrangement also prevents slipping and entangling-of the toweling or ridingof the same upwardly in back of the rollers S or W. as where it engages directly with the friction winding roller W, due to sudden operation or pulling of the toweling from-"the feeding or pay j ing out roller F, or. due to sudden stopping or snapping of the toweling feed structure in checking'th'e movement each time it is pulled;

The pinch roller assembly or frame '40 having the arcu'ate end-plates M and tie rods 42, also has its curved guide or guard plate 43 extended inwardly at its inner end asat-43ato form a stop or guard extension or'shelf to prevent the separator 63a from dropping down'between the arcuate plate 43 or rollers F or P and the roller I when the supply C exhausted. The shelf 43a may havecutou'ts or openings- 43b for the springs 53; The separator plate or follower 63a is also-pivoted in the'center to theinner ends of the arms 65a'as at 6411 to balance itself and the arms 65a are longer than the" arms 55in the other form. Also, theplate 36 has keeper openings or slots 36b near the opposite edges thereof'to engage or spring over notched catches 360-111 the'form of notched bars or posts outstanding from the plate i'S' and having beveled inner; ends or noses as shown so that the plate 36, will spring down under the catches at theopenings' andsnap into the that amaohine or cabinet can be loaded or reloaded in ajiffy.

g Operation In the. operation of the, deviceQassuming that.

the. cabinet is empty of toweling. the housing orv cabinet, proper is released'by turning; the locking screw 29. to disengage it from the bracket or keeper 3d whereuponit may be swung 90' degrees,

forwardly and downwardly on the hinged. connection or pivots. 28 against thevertical support ljbelow' the mechanismwiththe openside whichnormally fits or is disposed toward the vertical supportat the back disposed upwardly and the.-

open bottom at the rear or back, so that the side, top.- and front walls of the cabinet will form; a receptacle for receiving a. rollof. clean toweling. It, will also. serve: as a container for the toweling guide or pinch roll assembly 40, which. is removed,

from. its. operative position by swinging it. up.-

wardly .on. the pivots 4B..and removing it from. the. frame. It. will also support the soiled towel-- ing. roller S .or any other articles which might otherwise be mislaid, or difhcult to manipulate. during the loading oi the machine- The; soiled towelingroller S is'merely displaced from, the open bearings. or recesses, 69in the, upper ends of the bearings. 10. A length ofclean toweling T is then. unrolled from the clean. towel roll C and. with the: plate. 33 swung on its. pivot so as to dispose the partition or separator .36 forwardly and downwardly relative. to its normal verti al. position where. it forms. the. space 3.8 in connection p with the baok'mounting. plate lathe end of the towelingisthen passed under the. bottoin .of the machine in'back of the. rods 24 through thespace 38 whichhas been opened by the. forward tilting ascending soiled toweling, and can be swung clear 'of the back of the. machine to provide ready access thereto greatly simplifies the task of loading; Thetoweling is then extended over or under the. winding or take-uproller W and. the end portion. thereof wound upon the soiledtowel roller S which is placed in position in the bearings 10 and. pressed against. the roller W by the; tension of. the springs 16-. The plate 33 is then swung back into position with its vertical portion or partition 36 infront of the. ascending toweling where it is held bythe angular portion 31 frictionally and resiliently engaging the upper rod 24. With sumcient length of the clean towel depending below the machine in the form of a loop as shown in Figs. 1 and 2, the length of which may be varied as desired, the clean. roll of toweling 6 is then thrust or placed in position as shown in Fig. 1

v resting'upon the idle roller I and the partition notches 36a. The catches 360 may be secured to the plate. 16 by base flanges 36d secured by welding, riveting or otherwise to theplate, I6. A handle 36f'is also attached centrallyto the plate 36 to press down on the latter'to disengage the catches from'the openings 36b or for engaging the same after the toweling is passed around the 36' oan swing down and forwardly obviates the .roller S. The pivoting of the plate 33 so that part or separator 36 spaced above the bottom portion 33. The separating plate 53 which automatically floats with the pivoted arms 65 may be raised to facilitate insertion. of the clean towel roll and willxmove down as the clean toweling is dispensed therefrom but normally may assume the positionshown' in Fig. 3 but always keep the soiled toweling out of contact with the clean toweling continuously duringthe time when the latter is unwound from the roll C and being wound on the roller S. The pinch 'roller and guide assembly .or frame is then inserted in position by engaging the notches with the pivots 46 and swinging the samerearwardly and downwardly on said pivots over the feed roll F so that the pinch roller P will frictionally engage and press in the toweling on roll C to pass or snap by the periphery of the clean toweling roll C and move below the idle roller I permitted by the slots I in which the spindle 50 of the pinch roller P is journaled and the normal tendency of the springs 53 to hold the pinch roller at the inner ends of the slots. The placing of the clean toweling roll C in position as previously explained will cause the toweling T to pass over the feeding roller F and the idle roller I so that when the pinch roller assembly is placed in position as just described, the pinch roller will loop or press the toweling downwardly by pressure thereon between the idle roller I and the feeding roller F and will place the pinch roller and toweling under tension by pressure against the feeding roller F from the springs 53 due to the inclination of the slots SI and the tangential relation or convergency thereof toward the periphery of the feeding roller F and the tendency of the springs 53 to press or hold the pinch roller against the feeding roller F and toweling thereon below its axis I00 and at the same time the guard plate or guide 43 will be positioned over the feeding roller and the assembly or frame held in position by engagement of the notches 48 with the pins or lugs 49. The pinch roll is contained in an assembly which serves as a toweling guide and is separable from the rest of the mechanism thereby positioning the pinch roller after the toweling has been thrown or placed in position. This makes threading of the toweling unnecessary. Also, owing to the fact that the pinch roller is positioned under spring tension, no towel slippage is required to set the pinch roller firmly and in position pressing against the feeding roller with the interposed toweling. Most, if not all other machines, require motion of the toweling to accomplish this function. The machine is now ready to operate and when a clean wiping section of toweling is desired, the user merely grasps the clean toweling depending below the machine at the open bottom below the feeding roller F and adjacent the curled portion 34 and a downward pull is exerted thereon. Due to the frictional engagement of the toweling with the feeding roller F, the latter will be rotated as well as the pinch roller P and the idle roller I to unwind the toweling from the clean towel roll C; Due to the feeding and winding rollers being positively connected by the chain I04 on the sprocket wheels I02, the winding or take-up roller W will be rotated in the same direction as the feeding roller F thereby advancin the soiled toweling around the winding roller and causing it to be wound on the soiled towel roller S by reason of the latter and the toweling thereon being pressed against the winding roller W by the springs I6 which elevate the bearings 70 in the slots I2. By holding the soiled toweling roll in contact with the takeup or winding roller by spring tension instead of depending upon the gravity as in most, if not all other machines, this produces a more uniformly and tightly wound roll of soiled toweling, thus reducing the space requirement of the roll. The floating separator or plate 63 which can assume any position required by the changing sizes and positions of the toweling rolls is used to effect a conservation of space by using the space given up by the diminishing clean roll to accommodate the increasing size of the soiled towel roll.

In order to regulate the feedingor advancing of the toweling as well as the winding and the time interval of the perceptible or discernible signal which, as explained in my prior application, Serial No. 376,575, heretofore referred to herein, is audible in this instance due to the buzzing sound of the operation of the gears of the timing or clock mechanism I I5 and thus indicate to the user when the device is inoperative or when the toweling may not be pulled out, as well as give an audible, discernible or erceptible signal continuously during the period when the towel is normally used for the wiping operation or the period while held between the time when the towel is pulled or moved out and the time when it may be moved again, the following operation takes place. When the toweling is pulled to rotate the feeding roller F and the winding roller W, the latter will be permitted to rotate by the pawl I08 riding over the teeth of the ratchet wheel I06 but restraining the same against reverse rotation so that the toweling cannot be unwound from the soiled towel roller. By reason of the novel ratio of feeding, winding timing and time release mechanism, whereby the friction feeding and winding rollers are advanced other than an integral number of revolutions each time a length of toweling is pulled down or out for use and arranging the toweling so as to cause the strip of toweling to extend around or engage with the friction surfaces on said rollers at the major or practicable maximum portions of their peripheries, but more particularly by causing the engagement of the pinch roller P with the roller F as well as the soiled towel roller S with the winding or take-up roller W at a different point on the periphery of the feeding and winding rollers respectively when stopped after each cycle of operation or moving of the toweling to advance a clean section to wiping position thereby preventing undue wear on the friction surfaces on said rollers at any particular point as where the same point on the roller F stops in confronting position to the pinch roller P or one point on the winding roller W stops in confronting position to the soiled towel roller S at each operation, increase in the useful life of the roller surfaces is insured. In the particular arrangement shown, a different surface will be presented to the pinch roller for every multiple of four operations before repeating and before the same point is again contacted thereby preventing undue wear on the friction surfaces, emerypaper or sand paper of the friction or sand rollers constituting the feeding andwinding rollers and increasing the useful life of said roller surfaces a multiple 1 of or approximately four times their ordinary life. Theconstruction of the means for supporting and feeding the clean toweling as well as winding up the soiled toweling, the arrangement of the rollers and the manner in which the toweling is run through the machine as well as the construction of 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 insure 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 con tact with the take-up or winding roll by spring rend plates fll thereof-and betwee n the "feeding "toweling with the winding ,rollergW.over more renew/502 hensiominsteegd -of'jdepen'ding upon ygravity as in amost,{if*not all-r-othr machines; thus-noti-only producing a more "uniformly and -'-ti ght-ly wound r'ollof-soiled=towe1ingout'also-reducingzthekspaoe H e 4 t; rolled up 'into the cabinet-in the form-of a roller requirement of the 4 roll.
