DEVICE FOR WRINGING- WET LEATHER.

Application filed September 24, 1921. Serial No. 503,056.

To all whom t may Concern.'

Be it known that I, EDWIN F. HULBERT, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of IVisconsim'have invented a certain new and useful Improvement in Devices for IVI-inging l/Vet Leather, of which the following is a spe'cication.

The invention relates to a wringing wet leather.

Heretofore in wringing out wet leather it has been customary to use an apparatus in which half of the hide is wrung out during one operation and then the other half wrung out during another operation, necessitating a rehandling of the hide for a complete wringing. The object of the present invention is to'providea hide-wringing device in which vthe entire wringing operation is carried'V out without rehandling the hide.

A further object of the invention is to provide a hide-wringing device inwhich the hide is placed on a movable platen which is moved to, bringthe hide into contact with a wringing roller and then by tilting said platen the hide is brought into Contact with another wringing roller to` accomplish the wringing operation.

The invention further consists in the several features hereinafter set forth and more particularly defined' by claims at the conclusion hereof.

In the drawings: Fig. 1 is aside view' of a device embodying the invention; Fig. 2 is a front view thereof, parts being shown in section; Fig. 3 is a section taken on the line 3 3 of Fig. 2, with the platen in one of its wringing positions; Fig. 4 is a detail plan View of the platen.

Iny the drawings the numeral 5 designates the frame of the machine, 6 a power pulley drivingly connected through a suitable clutch 7 with a shaft 8 carrying a gear 9 device for meshing with a gear 10 and a gear 11 mesh-V ing with a gear 12. The gear 1() is mountedk on a shaft 13 which carries a sprocket 14 connectedV by a chain 15 toa sprocket 16 'on a shaft 17.

The shaft 17 carries a gear 18 meshing with a gear 19 on ashaft 20.v The shaft 17 carries a sprocket 21 connected by a chain 22 with a sprocket 23Qo`nk the shaft v24 of a wringing roller 25. The shaf-t.20 carries a sprocket 26y connected by Cha-in 27 with a sprocket 28 on the shaft 29 of a wringing.

roller 30. As the shaft 20, due to the ,f ear-r ing connection 19, 18, revolves in the opposite direction to that of the shaft 17, the roller 25 is rotated in the reverse direction to that of the'roller 30. Each of the shafts for the wringing rollers are mounted in bearing boXes 31 yieldingly held in a lowerv position by means of springs 32.

A platen for the hide is formed bl side members 33 and

shafts

34, 35 and 36'. hafts 34' and 35 carry

pressing rollers

37 and 38, respectively, and

gears

39 and 40, respectively, at their ends while shaftv 36 forms al pivot about which the platen may tilt so as to bring either the gears 39 into driven engagement with gears 41 on the shaft v2,4, or the gears into drivenengagement with gears 42 on the shaft 29. 'An endless apron or belt B passes over the

rollers

37 and 38 and fornis a receiving and discharge table for the hide H, as well as a' guide'for'it during the wringing opera-tion. The shaft 36 is journalled in slidable bearing blocks 43 mounted in inclined guides 44 so as to bring the platen' from its'l lower hide-receiving position, shown in Fig. 1,I to its operative position, shown in Fig. 2, and for thisv purpose I use Sets of

toggle links

45 and 46 and connecting rods 47-operatively connected to the joints of these links and to crank disks 48 mounted on a shaft 49 upon which the'gear 12 isvloosely mounted. The gear 12 is adapted to be drivingly connected with the shaft 49' by means of a pin clutch including a pin 50 slidably mounted in a collar 51 keyed to the shaft 49 and moved by aspiring 53 into locking engagement with either one of two recesses 54 in the hub of the gear 12, said pin being automatically withdrawn from the gear 12 when' either one ofthe cams 55 on a rod 56 are positioned in the groove 57 in the collar so as to engage ai groove 58 in the pin 50 tok draw it out of engagement with the gear 12, which action' occurs after the shaft 49; hasl made about 1'00 half a revolution, as indicated in2 Fig. 3L The rod 56'isf normally urged upwardly by means of a spring 58 and it is connected-'to anarin59 on shaft'60 operated by ay treadle 61. When the lower cam 55 isfinovedIk out 1'05 the pulley. On' a release/of the tilad'l the L10 upper cani 55 is moved out of engagement with the pin 50 which engages the gear 'l2 andthe platen is moved from the position shown in full lines in F ig. 3 back to its lowered position, at which time the lower cam 55 diseiigages the pin 50 from the gear l2.

Then the platen is in its upper position it may be tilted in the manner previously described so that one set of wi'inging rollers, such as 30 and 38, and then the other set of wringing

rollers

25 and 37 are driven through the gearing connections previously described. To eifect this tilting oi' the platen, .i provide cam shafts 62 at each end of the

machine carrying cams

63 and 64 and I connect these up tor conjoint operation from either one ot two shai'ts 65 by

means ot gears

66 and 67 connecting each shaft 62 with theadjacent shaft 65 and by means of sprockets 68 on said shafts connected by a chain 69, each of the shafts 65 having a hand lever 70 for turning it which, through the gearing connection just described, causes a rotation ol both of the shafts 65 and the cam shafts 62. Then one of the levers 70 is turned in one direction the cams 66 come into engagement with the members 33 of the platen, causing its front end to tilt upwardly to bring the gears 4f() into mesh with the gears 4-2 and when one ot the levers 70 is turned in the opposite direction-the cams 67 come into engagement with the members 33 of the platen, causing its rear end to tilt upwardly to bring the gears 39 into mesh with the gears 41.

With this construction, when the platen is in its lower position the hide is placed thereon and on a depression of the treadle 61 the platen is raised to a wringing position. Then by tilting the platen to bring the

gears

40 and 42 into mesh while these gears are revolved through the driving connection with the shaft 8, the lower half of the hide, as shown in Fig. 3, is wrung between the rollers 8G and 38 and as the upper run or" the apron B moves toward the left. Then by tilting the platen Vto bring the gears 39 and il into mesh the travel of the apron B is reversed and the other half of the hide is wrung between the rollers 35 and 37. Thus the whole hide is wrung out and the platen then lowered for the removal of the hide. rlhe wringing operation is thus quickly accomplished with minimum amount of handling of the l desire it to be understood that this invention is not to be limited to any specific form or arrangement oparts except in so far as such limitations are specified in the claims.

What I claim as my invention is:
