Application March 23, 1936, Serial No. 70,242 3 Claims. (or Biz-c8) My invention relates to a towel dispensing cabinet and I declare the following tobea full, clear, concise and exact description thereof sufficient to enable anyone skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings in which like reference characters refer to like parts throughout the specification.

The object of my invention is toprovide a towel cabinet that can be hung on the wall and will occupy less wall space and hold a larger" supply of toweling than has been possible heretofore. Furthermore, the object is to provide a towel timing control mechanism for said cabinet that will work normally under any and all con-I ditions. More particularly it will not be affected by the temperature of the room inwhich" it is located nor will the dust accumulating thereon in any way'interfere with the normal operation or function of the several parts of the mechanism.

anticipates this desirable feature by providing a timing mechanism, whereby a predetermined amount of time must intervene between one pull and the successive pull on the towel.

The object will be understood from the drawings in which Fig. l is a perspective view of the towel cabinet.

Fig. 2 is a horizontal sectional view taken on the line 2 2 of Fig. 3, parts being in full lines.

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 1. i

Fig. 4 is a detailed view somewhat enlarged showing a perspective of a rocklever and immediate parts employed, enlarged.

Fig. 5 is a detailed view showing a perspective of towel actuating frame and its imme diate parts employed.

Fig. 6 is a front elevation.

Fig. 7 is a-detail view showing a perspective of a casing for housing certain gears employed.

Referring more particularly to the drawings, the device embodies a casing I having hinged thereto at 2, a door 3, latch member 4 that is controlled by a lock 5 operated by key 6. The turning of key 6 will actuate latch 4 to locked or unlocked position.

Cabinet I has a bottom portion II] that supports the towel actuation mechanism II, hereinafter described. Furthermore, mechanism H is also secured to the lateral sides l2, ll of cabinet I by bolts l3, nuts I4 and spacing sleeves 15. The sides l1, I! of the towel actuating frame I8 support a rock shelf [9. Shelf I9 is made preferably of metal. It has its sides turned up at andwelded to the contiguous surfaces of side bars 2|, 2|. .Bars 2|, 2| are fulcrumed upon stationaryshaft 22. Shaft 22 has bearings at either end in sides [1,. I! of the towel actuating frame 18. A spacing sleeve 23 is mounted on stationary shaft 22 between the contiguous surface of bars 2|, 2|, whereby to aid in holding said bars 2|, 2| in given spaced relation to each other. The outeror free ends of bars 2|, 2! are bent at an angle at 24 to form a ledge, whereby to prevent the towel roll 25 from rolling therefrom. Furthermore, a bar 26 having reduced ends is mounted to the extreme outer or free ends'of bars 2|, 2|, whereby to hold them in spaced relation at that location.

Shelf I9 is normally rocked upwards on its fulcrum shaft 22 by means of

flat springs

30, 30.

Springs

30, 30 are secured by rivets M or otherwise to laterally projecting shelves 32 made integral or operatively connected with bars 2| 2|. The lower ends of said springs 30 rest in front of laterally projecting studs 33 mounted to sides I7, I'!- of frame Hi. This spring actuation of shelf I 9 permits said shelf to rock upwards as the supply roll of towel 25 diminishes in size, whereby to allow space therebeneath for the gradually increasing diameter of the soiled towel roll. Said springs 3t, 30 are sufilciently strong to pre vent shelf l9 from rocking below a horizontal position under the weight of supply roll of towel 25. As rock shelf l9 moves downward the free ends of

springs

30, 3! will press harder against laterally projecting

pins

33, 33.

The means forlocking the towel actuating mechanism for intermittent periods of time embodies roller 40. Roller 4|! is made preferably of a hollow cylinder 41 having

end discs

42, 42 welded thereto. End discs 42, A2 provide hubs for mounting axles 43, M. Axles 43 and A l are riveted at 45 to

end discs

42, 42 in each instance. Axle 43, however, is reduced at 46 for mounting spur gear 41 that is keyed or forced thereon by a drive fit, whereby to turn therewith and again reduced at 48 to slide on its bearing on sides H, H of the towel actuating frame.

This sliding or longitudinal movement of roller 40 and axle 43towhich spur gear 41 is fixed will allow said spur gear 4'1 to move in and out of mesh with idle or middle spur gear 50 that has a loose bearing, whereby to turn thereon on inwardly projecting stud 5|. Idler spur gear 50 is in mesh also with a third spur gear 52 mounted to turn on an axle 53 that is fixed to the end of roller 54 much in the same manner that axle 43 is mounted to one of the end discs 42 of! roller 40.

Spur gear 41, idler 50, and spur gear 52 are encased in a casing 55 that has one side open, the one that is disposed adjacent the inner Wall of side I'I. Casing 55 is equipped with apertured

extensions

56, 56, whereby it can be screw bolted to the inner surface of side I'l. Spur gear 41 connected to roller 40, idler spur gear 56, and spur gear 52 connected to roller 54, will cause said

rollers

40 and 54 to revolve in the same direction.

' Axle 53 of roller 54 projects through one of the sides H of frame I8 and extends laterally therefrom. A cam or eccentric 60 is mounted to turn with axle 53. It is fixed to axle 53 by pin 6| extending through boss 62 of cam 60 and engaging axle 53. When cam 60 turns it engages roller 63 mounted to revolve on lateral projecting stud 64 having a tight fitting bearing in arm 65 of rock lever 66. Rock lever 66 is pivoted at 6'! to a laterally projecting stud mounted in one of the sides I? ofmechanism II. The extreme outer end 68 of lever 66 is offset at 69 and has mounted thereto a laterally projecting pin I0. 'Pin"'l0 extends laterally through a loose aperture on the lower or free end of piston rod II. The upper end of rod II is connected to a piston I2 in cylinder'13. A set screw I4 mounted in the upper end of cylinder I3 controls the amount of .air admitted to the upper end of cylinder I3, whereby to govern the velocity with which piston I2 ascends in cylinder I3. Cylinder I3 is mounted to one of the sides ll of mechanism I I by a right angled bracket 15 having a bifurcated end I6 which straddles screw 14 mounted in the upper end of cylinder I3. Bracket 15 is attached by bolts or rivets I8, 18 to one of the sides I! of frame I 8.

The opposite end of rock lever 66 has attached by rivets 80, 80 a bracket 8| offset at 82. A weight 83 is formed on depending portion 84 that lies inparallel relation to the adjacent surface of bracket BI and attached thereto by rivets 85, '85. Weight 83 will tend to rock lever 66 into the full line position indicated in Fig. 5, whereby piston 72 will be in its uppermost position in cylinder 13.

The means for locking roller 40 temporarily against rotation embodies a pin 86 mounted and projecting laterally from axle 53. When lever 66 is in dotted line position shown in Fig. 5, pin 86 will be below the overhanging member 81 securely fixed to the upper part of 88 of rock lever 66. When rock lever 66 is moved to full line position shown in Fig. 5 pin 86 will be uncovered and

rollers

40 and 54 can be again turned through one revolution or until cam 60 rocks lever 66 into dotted line position shown in Fig. 5.

The means for temporarily holding towel roll 25 when loading the cabinet, embodies a shelf 9I preferably made of metal. It comprises

upstanding end ridges

92, 93 and is attached to rock

arms

94, 94 pivoted at 95, 95 to the forward lower 1

extensions

96, 96 of sides IT, I! of frame I8. A

of axle 44 when

rock arms

94, 94 are swung upward in full line position illustrated in Figs. 1 and 3. Moreover, this. is the position said

arms

94, 94 will occupy when the cabinet is in use.

The means for holding toweling 25 against the surface of roller 40, which is covered with sand paper or other suitable friction producing material embodies a Weighted roller IOI supported to revolve upon an axle I02 carried in swinging arms I03, I03 that are pivoted at I04, I04 to sides I1, I! of frame I8.

The soiled toweling 25 is accumulated upon weighted roller I 05 having arbors I 06, I06 that extend into open slots I01, I01 formed in sides I1, I! of frame II, whereby said roller I05 can move upward as toweling 25 is wound thereon. When free from toweling 25, roller I05 will rest at its lower level upon the adjacent surface of roller 54, whereby said roller 54 which is covered on its outer surface with sand paper, will cause accumulating roller I05 to revolve therewith and wind the soiled toweling 25 thereon.

The means for limiting the rotation of roller 54 in a clockwise direction embodies a ratchet II fixed to turn with shaft 53 of roller 54 and a pawl III pivoted at II2 to one of the sides I! of frame II. Pawl III has a counterweighted arm H3. It will allow the teeth of ratchet IIO to pass in a clockwise direction but not in a counterclockwise direction. This clockwise rotation of roller 54 assures a counterclockwise rotation and not otherwise of accumulating roller I05, whereby to wind soiled toweling 25 thereon.

The means for automatically closing the opening where soiled toweling 25 re-enters the cabinet contemplates a rock lid II having trunnions formed at H6, H6 which project into suitable bearings formed in sides I I, I! of frame II. The free end of lid II5 rests when closed upon clips H1, H1 attached to the upstanding edge I I8 adjacent sides I! of a partial casing II9 disposed between sides IT, IT, whereby to leave an elongated opening at I20 for the passage of towel 25. A flat spring I 2| is fastened by screw bolts I22, I22 to the top of lid I I 5. Its free upstanding part I23 will bear against the inner back surface I24 of cabinet I, whereby to hold lid I I5 normally closed or against the upper surface of clips II'I, II I on upstanding edge II8 of casing II9.

Cabinet I is provided with a door I25 mounted on hinges I26, I26 fastened to a front edge of casing I. Latch 4 heretofore mentioned engages an edge I29 formed by making an elongated aperture in casing I30 of door I25, whereby to hold said door I25 closed and locked.

Frame I8 is supported in cabinet I not only by the bolts I3 mentioned above but also by a ledge I3I welded or otherwise secured to back wall I33.

When loading toweling 25, door I25 will be opened and loading shelf 9| swung down into full line position illustrated in Fig. 5. The towel roll. 25 will be placed upon rock shelf 9i. The free end of toweling 25 will be led down between bar 26 and the free edge I32 of rock shelf l9, then over the far side or under surface of shelf 9|, then down in front of weighted roller IDI thence thereunder partially around the back of actuating roller 40 up over the rod 91 which will be located above the lower circumference of roller 46 when

arms

94, 94 are swung upwards into dotted line position shown in Fig. 3. Toweling 25 passes then down below cabinet I with a long I29 formed between the free end of lid H5 and the adjacent edge H3 of partial casing H9, lid

H5 being opened against the tension of spring actuating'roller 43 will be revolved and thereby turn the train of

gears

41, and 52, whereby to cause rear actuating roller 54 to revolve in the same direction and at the same speed. This actuation of roller 54 will turn accumulating roller I85, whereby toweling 25 will wind thereon.

Should it bedesirable to spin roller 40 or to pull the towel freely from roll 25, the operator will move roller 45 longitudinally to the left, whereby to withdraw gear 41 on one end of roller 4 from meshing with idler gear 50.

When gear 41 is in mesh with gear 50 which in turn is in mesh with gear 52 tight to axle 53, the turning of axle 53 will rotate cam or eccentric which will engage roller 63 mounted to rock with lever 66 on its fulcrum 61;

This rocking of lever 66 will elevate weight 83 and lower piston 12 in its cylinder 13. Overhanging member 81 on lever 66 will be brought in the path of pin 86 on axle 53 and thereby temporarily arrest the further turning of

rollers

40 and 54 until piston 12 has ascended in cylinder I3 and lever 66 under the weight of 83 has rocked back to normal or original position. The time between pulls on towel 25 can be governed by regulating set screw 14 which controls the admission of air to cylinder 13. Each pull on towel 25 allows for one complete revolution of

rollers

40 and 54 before arresting the motion, as above described.

'It will be observed that auxiliary shelf 9| heretofore mentioned for temporarily holding towel roll 25 when loading the machine is a swinging shelf, whereby it serves not only for the purpose of a temporary shelf but also when in closed position as illustrated in Figs. 1 and 3. It serves also as a front partition.

The means for holding door 3 in correct position with reference to cabinet l embodies a projection I36 on door 3 and a recess I31 on the front edge of cabinet I.

When auxiliary swinging shelf 9! is in dotted line position shown in Fig. 5 or full line position shown in Fig. 1 blade I98 will lie opposite shaft 44, whereby to prevent the roller 40 from moving longitudinally to disengage spur gear 41 from idler 50. This will prevent spinning the towel when the cabinet is closed.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is as follows:

1. In a towel dispensing cabinet, a towel supply, a rock shelf for supporting said towel, a roller for accumulating said towel thereon, open bearings for supporting said accumulating roller, other rollers mounted in said cabinet for rotating said accumulating roller, a shaft for supporting one of said actuating rollers, a pin mounted in said shaft, a lever for engaging said pin, whereby to arrest rotation of said actuating rollers, a piston rod connected with said lever, a piston connected with said piston rod, a dash pot in which said piston moves, whereby to control the movement of said lever and a cam member mounted on said shaft, whereby to rock said lever to locking position.
