HIDE-W'ORKING MACHINE.
Application filed May 9, 1922. Serial No. 559,654.
useful Improvement in Hide-forking Machines, of which the following is a specification.
This invention relates to hide working machines and has for its object the provision of means for removing the moisture from the hide being operated upon, and also from the hide supporting roll after the hide has been removed therefrom.
The invention consists in providing the machine with two idler rolls above the knife cylinder over which is stretched a thick endless blanket with which the hide supporting roll coacts at a point between said idler rolls.
The invention further consists in means for retaining the endless blanket taut under certain conditions.
The invention further consists of certain novel features ofconstruction and arrangement of parts which will be understood readily by reference to the description of the drawings and to the claims to be here-' inafter given.
For the purpose of illustrating the inven tion, one preferred form thereof is shown in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of'which the invention consists can be variously arranged and organized, and that the invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described, except as required by the scope of the appendedclaims.
Of the drawings:
Figure 1 represents an elevation of a hide working machine with mechanism applied thereto embodying the principles of the present invention, and I Figure 2 represents a vertical section-of the same.
Similar characters indicate like parts throughout the several figures of the drawings.
In the drawings, 10 and 11 represent two end frames of the machine connected together by the tie'girts 12. Mounted in suitable hearings in the end frames 10 and 11 is the working cylinder 13 having the usual operating knives 14 thereon.
One trunnion 13 of the working cylinder 13 extends beyond the outer face of the end frame 10 and has securedthereto a driving pulley 15 by which the working cylinder 13 may be revolved at any desired speed in the direction indicated by the arrow a on Fig. 2.
Above the working cylinder 13 and revolubly mounted in boxes 16 is a roll 17. Each of the boxes 16 has secured thereto a threaded member 18 extending through a lug 19 formed upon a bracket 20 secured to an end frame 10 or 11. Between the lug 19 and an adjustable member 21 threaded to said member 18 is a spring 22 normally forcing the roll 17 toward the front of the machine. Nuts 2324 threaded to the outer end of the member 18 and co-operating with the lug 19 serve to limit the forward move ment of said boxes 16.
To the upper end of each end frame 10-11 is secured a bracket 25having a lug 26 through which extends a threaded member 27 the lower end of which is connected to the box 28 in which is revolubly mounted one end of the roll 29. The member 27 has threaded thereto the nut 30 between which and the lug 26 is interposed a spring 31 which forces the roll 29 downwardly, the downward movement being'limited by the nuts 32-33 threaded to the member 27 above the lug 26. r
The roll 17 has trunnions 34 extending into the boxes 16, and the roll 29 has trunnions 35 extending through the boxes 23. Both rolls 17 and 29 are idler rolls and are not positively driven.
The work supporting roll is provided at its opposite ends with trunnions' 42, mounted in hearings in the rocker frames 43 pivoted to brackets 41 on the outer faces of the end frames 10-11 at 44.
The rocker frames 43 have outwardly ex- 1 tending arms 45 to each of which is pivoted at 46 a-link 47 the opposite end of which is pivoted to the crank disks 48 by which rocking movement is imparted to the rocker frame 43. The link 47 is composed of two end members, each provided with an ear 4'? to which is threaded the opposite ends of the connecting member 49 by which the length of said link may be varied. The crank disk 4:8 is surrounded by a brake member of any suitable construction.
The trunnion 42 has mounted thereon the gear 59 which has pointed teeth adapted to mesh with the teeth of a driving gear (not shown) when the work supporting roll is in operative position. This driving gear and the mechanism for rotating the same are substantially as shown and described in Letters Patent No. 1,339,201 issued to me May 4, 1920, and to which reference may be made for a description of the general operation of the machine. I
Suspended from the trunnions 39 and 42 are the swinging frames 80, each having a slot therein in which is mounted a box 81, said boxes 81 having revolubly mounted therein the roll 82 provided with a covering of relatively thick yielding material such as soft rubber, all as in the before mentioned patent.
Secured to the front face of each swinging member is a bracket 85 provided with an ear 86 through which extends a threaded rod 87, the opposite end of which is secured to thebox 81.
The rod 87 has a nut 83 mounted thereplied.
In the former patent the rolls 17 and 29.
were driven by gears and coacted with the feed roll 40 to feed the hide in the direction indicated by the arrow 7; on Fig. 2.
The present invention consists in omitting the driving gears from the rolls 17 and 29 and making them idler rolls over which is placed an endless blanket 90 of absorbent material, this blanket extending from one roll to the other in such a manner that when the feed roll 40 is in operative position, it will contact with said blanket and press upon the same to such an extent that said blanket will cover a considerable portion of the periphery of said feed roll 40 or the same proportion of the hide on said roll.
This contact of the feed roll 4:0 with the blanket 90 will cause the blanket to be moved in the direction indicated by the arrow 0 on Fig. 2.
The blanket 90 also passes over a tautening roller 91 mounted in boxes 92 slidably mounted in the brackets 93, said boxes having extending therefrom the freely revoluble members 9 1 threaded to the ends 95 of said bracket 93. i
The members 9 1 are provided with heads 96 by which the threaded members 94 may be turned to adjust the position of the slidable boxes 92 and thereby make the blanket 90 as taut as desired. I
When the hide is being operated upon, the pressure of the blanket 90 on the hide will remove all the moisture from the hide and after the hide has been removed from the feed roll 410 the blanket 90 will come into direct contact with the roll and thus remove all moisture from the roll. This action will leave the roll dry or substantially so, ready to receive another hide and secure a better grip thereon than would be the case if the feed roll was wet and slippery.
In the operation of the machine when the hide supporting roller 40 is in position for the hide to be placed thereon, the endless blanket 90 is slack upon the rolls and no movement can be imparted thereto. As soon, however, as the hide supporting roller 4.0 is moved toward the roll 17, the first action thereof will be to pinch the blanket 90 between said hide supporting roller 40 and the roll 29, thereby causing the blanket 90 to be moved in the direction indicated by the arrow 0 on Fig. 2 of the drawings.
lVhen the hide supporting roller 40 reaches the extreme of its movement toward the roll 17, said hide supporting roller will force a portion of the blanket between the idler rolls 17 and 29 inwardly as indicated in Fig. 2 of the drawings, thereby tautening the blanket and causingit to be pressed firmly against a considerable portion of the hide supporting roller 40 or the same pro portion of the hide supported thereon.
Most of the moisture on the hide or upon the periphery of the hide-supporting roller will then be absorbed by the blanket 90 as it moves in the direction indicated by the arrow 0 on Fig. 2 of the drawings, the most of the squeezing action to remove this moisture being performed by the coaction of the hide supporting roller 10' and the roll 17.
Before operating the machine, the blanket 90 is preferablyvmoistened as better results are obtained in this manner.
By using the absorbent blanket in the manner described, the hide is left in better condition when it is removed from the roll 40 and the absorption of the moisture from the roll 40 by the blanket makes it possible to feedthe hide more easily than heretofore.
Greatly improved results are attained by the machine when the endless absorbent blanket is used, while at the same time the devices heretofore used to positively drive the rolls 17 and 29 are found to be unnecessary.
The improvement is inexpensive to construct and readily applied to either a new or old machine.
It is believed that the operation and many advantages of the invention will be readily understood without further description.
Having thus described my invention, I claim:
1. The combination with a revoluble knife cylinder; a hide support movable toward and from said knife cylinder; and an endless belt of absorbent material supported above said knife cylinder and adapted to contact with said hide support when it is in position for the hide to be acted upon by said knife cylinder.
2. The combination with a revoluble knife cylinder; a bed roll adapted to coact therewith; a hide supporting roller above said bed roll and movable therewith toward and from said knife cylinder; and amovab-le blanket of absorbent material supported above said knife cylinder in position to contact with said hide supporting roll when said bed roll is coacting with said knife cylinder.
3. The combination with a revoluble knife cylinder; a bed roll adapted to coact therewith; a hide supporting roller above said bed roll and movable toward and from said knife cylinder; an idler roll above said knife cylinder; another idler roll above said hide supporting roller when in operative posit-ion; and a movable blanket of absorbent material on said idler rolls adapted to contact with said hide supporting roller at a point between said idler rolls.
4. The combination with a revoluble knife cylinder; a bed roll adapted to coact therewith; a hide supporting roller above said bed roll and movable toward and from said knife cylinder; an idler roll above said knife cylinder; another idler roll above said hide supporting roller when in operative position; an endless belt of absorbent material on said idler rolls adapted to contact with said hide supporting roller at a point between said idler rolls; and means for tautening the belt.
5. The combination with a revoluble knife cylinder; a bed roll adapted to coact therewith; a hide supporting roller above said bed roll and movable toward and from said knife cylinder; an idler roll above said knife cylinder; another idler roll above said hide supporting roller when in operative position; an endless belt of absorbent material on said idler rolls adapted to contact with said hide supporting roller at a point between said idler rolls; a belt-'tautening roller; and means for adjusting the position of said roller.
