The cabinet consists of sides 15' and 16, back 17 top 18, bottom 19` and a frontV foot panel 2O forming a pocket for the reception of soiled toweling. 'Y

The front door 21 is hinged as indicated 'at 22 and has anopening'28 at a suitable height .95 for convenient use of thel towel. This `open'- ing is normally closed by `a slide door 24 which is provided with tongues 25 slidable in grooves 26 and Aprovided with a hinged'pivot member 27. *A slot 28 is fprovidedin the 100 front foot panel 20 for the'treadle. f

Vdriven rollers are preferably covered with feed mechanism housing.

rubber so aste provide the necessary friction for 'feeding the toweling. A guard 38 is pivotally suspended beneath the idle roller 36 to prevent creeping of the toweling about the roller.

A guard is pivotally suspended from the driven roller35 and consists of a plurality of spaced hangers 39 which are rotatable in ,grooves formed in the roller 35 and are secured at their lower ends by a bar 40, and is adapted to prevent creeping of the toweling about the roller.

A A guard 41 is pivotally suspended and normally supported by the toweling on roller 35 and is adapted to prevent the toweling from above engaging the lower rolls, and may be raised to permit threading of the web.

The idle rollers are rotatably mounted in bearing blocks 42 which have fiatted sides and are slidable but non-rotatable in slots 43 formed in the side members 44 and 45 of the Springs 46 have their opposite ends respectively secured in the bearing blocks and to the roll housing, and

urge the idle rollers into contact with the driven or feed rollers.

. The driving mechanism for the feeding mechanism` consists of sprockets 47 and 48 secured on the journals 49 and 50 of feed rolls 35 and 34, A sprocket 51 rotatably vmounted on a pivot 52, and a circumambient sprocket chain 53 cooperating with `the three sprockets, the ends of journals 49 and 50 be- V-ing `rotatably mounted in bearings secured in the end plate 54. A

Rotatably mounted on pivot 52 is a ratchet 55, which cooperates with a pawl 56 which is pivotally secured at 57 to the sprocket 51, a spring 58 urging the pawl to cooperate with the sprocket.

Fixedly secured to or integral with the ratchet is a sprocket 59 which cooperates with a chain 60, the pivot 52 being secured in the housing plates 44 and 54.

The ournals at the other end of rollers 34 and 35 are rotatably mounted in bearings secured in the plate 45 as sho-wn at 61 and 62.

A back plate 63 together with end plates 45 and 54 and intermediate plate 44 completes the housing for the feed mechanism and is removably mounted in the cabinet by means of a rear angle support 64 the horizontal leg ofV which is bent at right kangles forming brackets 65 which are secured to the sides of the cabinet. The vertical leg is provided with slots 66which are adapted to receive the side and intermediate walls 45, 54 and 44, thus gositioning the housing in the cabinet.

crews 67 may be provided for Xidly securing the housing in position, if desired. The forward end of the housing is supported by brackets 68 and 69 which are mounted on the cabinet sides.

The actuating mechanism for the driving mechanism consists of a treadle `7() which is pivoted at 71 and operates through a slot 28' inthe. front foot-panel. Aconnecting rod 72 -is secured at one end to the chain 6() which cooperates with the sprocket 59 and has the other end attached to the treadle through an 'interposed tension spring 73, Vthe other end ofchain 60 being connected topa lever 74 which is pivoted at 75 and which is resiliently retracted by a spring 76, which is anchored to the side of the cabinet.

The lifting mechanism for the slide door consists of a connecting rodv 77 connected at one endA to the treadle and at the other end to a chain 78 which cooperates withk `a sprocket or hub 79 which is integral with a lever 80, the sprocket being rotatably mounted in a housing 81 which is secured to theside of the cabinet. n y i The hinged pivot member 27 is secured adjacent the lower edge o-f the slide door and consists of a strap member 27 to which is hinged an ear 82 intowhich is pivoted a connecting rod 83, the other end-of this connecting rod being pivotally connected' at 84 to lever'80. Y Y Y The retarding mechanism forvthey closing of the slide door consists of a connecting rod 85 which has one end connected to the treadle 70 and the other endconnectedl to a lever 86 which has one end pivotally secured as at 87 to the side of the cabinet, the other f end cooperating with the connecting rod88 of an air cylinder 89, this air cylinder being of the usual construction having a Vregulating valve 90 for governing the` retarding action of the piston, this cylinder being pivotally mounted as indicated at, 91. .i y f The governing means for the feeding mechanism consists of a pawl 92 which isv pivotally mounted on plate 54 as indicated at 93and is adapted to lock the chain 53 against movement by cooperationof the tongue 94 with the chain rollers, an extension 95 having pivotally connected thereto a connecting rod 96 which is slidable in the guide 97 and has a recess formed inside which is adapted to c-ooperate with a leaf spring 98 to resiliently lock the pawl 92 in engagement with the chain 53. Secured to the lower end ofjrod 96 is a yoke 99 which straddles connecting rod 72 which is freely slidable in the yoke. Adjustably secured on connecting rod 72 are two collars 100 and 101 which areadapted to cooperate with the yoke 99.

The web path follows from the roll of toweling 33 up the inclined front as indicated at 102 thence over the cylindrical member 31, thence, downwardly and back of rollers 34 as indicated at 103 thence under and between rollers 34 and 36, a loop being formed at 104 extending to the bottom of door opening 23 upwardlyover roller 35 thencebetween rollers 35 and 37, thence being free to deposit inthe receptacle formed at cooperating with any portion of the toweling,

the end of the towel is thenv passed upwardly between rollers 34 and 36 `and suflicient towel drawn'through to form the loop 104 the end 4of the towel being then passed lunder deflector 41 and downwardly between roller-s 35 and 37. The device is then ready for use.

The operation of the towel cabinet is as follows: 1

With the front door closed the treadle is depressed which through connecting rod 77, chain 78, sprocket 79, swings lever from the position shown in Fig. 3 vto that shown in Fig. 2 whichthrough connecting rod 83 raises slide door 24 from the position shown in Fig. 3 to that shown in Fig. 2. Coincidently the piston in cylinder 89 is retracted through connecting rod 85 and lever 86 setting the retarding mechanism. Coincidently through spring 73, connecting rod 72, chain 60, ratchet 55 is rotated coincidently rotating sprocket 5'1by cooperation with pawl 56 and driving thereby sprockets 48 and 47 through chain 53, thereby feeding a length of toweling depending on the spacing of the collars and 101; K

As the treadle reaches the bottom of its stroke collar 101 engages yoke 99, pulling down connecting rod 96 and causing tongue 94 on pawl 92 to engage chain 53 preventing further movement of the towel, the spring 98 engaging recess 107 and retaining the pawl in locked position. As the treadle is released the weight of the slide door `and various springs react against the piston in lcylinder 89 which retards the movement of the slide door 24, spring 76 retracting chain 60 and coincidently ratchet 55 preparatory for the next operation; The final return movement of treadle 70which coincides wit h the final closing movement of slide door 24 permits collar 100 to cooperate with yoke 99, raising connecting rod 96 and releasing tongue 94 from chain 53.

From the foregoing it will be noted that there can be no feeding movement'of the toweling until the full cycle is completed after depression of the treadle. .The feeding mechanism vis positively vlocked by the pawl 1 92 during the entire return movement of the treadle, which is obviously coincident with the closing of the slide door.

The device is sanitary, does not require contact of the hands with any portion of soiled toweling, the toweling is ralways enclosed except during the time ofu'se and there is no possibility of soiled towell being presented Having described an operative device, it will be vunderstood that variations in construction and arrangementv of parts which are consistent with the appended claims may be resorted to without detracting from Athe spirit or scope of the invention or-sacriiicing any of its advantages.
