CLUTCH MECHANISM FOR MACHINES FOR WORKING HIDES.

SPECIFICATION forming part of Letters Patent 110,497,146, dated May 9, 1893.

Application filed January 25,1893. Serial No. 459,703. (No model.)

To all whom it may concern.-

Be it known that I, GorTLInB F. TINNEY, of New York, in the county and State of New York, have invented a new and Improved Clutch Mechanism for Machines for Working Hides, of which the following is a full, clear, and exact description.

My invention is an improvement in a class of machines which are adapted to work or break raw hides, for the purpose of rendering them soft and pliable as required in the process of converting them'into leather. Such working or breaking is ordinarily effected by coiling the hides upon a shaft, or drum, and then reversing the motion so as to uncoil them.

I have devised an improved, automatic, reversing machine which is distinguished by a novel and compact arrangement of cam, gear, and clutch mechanism, the same being connected with the driving shaft and drum, wherein the hides are temporarily attached, as hereinafter described.

Reference is to be had to the accompanying drawings forming a part of this specification, in whichsimilar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improvement With part removed. Fig. 2 is asectional side elevation of the same on the line 2-2 of Fig. 1. Fig. 3 is aface view of the cams and Fig. 4 is an inverted plan view of the fastening block for securingthe hides to the drum shaft.

The hides to be treated are attached to the drum, A, which is composed of the shaft, B, journaled in suitable bearings arranged on the frame of the machine, and on the said drum shaft are secured the heads 0, O, O

, carrying a series of bars D placed equal distances apart and arranged in a circle, as is plainly shown in Fig. 2, some of the said bars being removable to permit of conveniently placing the leather in the drum.

The drum shaft B is provided on the opposite sides of the middle head 0 with recesses B fluted longitudinally and adapted to be filled by a block B formed on its under side with longitudinally-extending ribs B corresponding to the flutings in the recesses B, each block 13 being also provided at its ends with lugs 13 secured by set screws or other means to the shaft B. The dampened and slightly lubricated hides are fastened at one end by the blocks, B to the drum shaft, on either side of the head 0', so that theinterior of the drum is completely filled with the material to be treated, it being understood that the several hides wind one upon the other in the drum between the shaft B and the bars D. Now, when the drum A is revolved in one direct-ion, the hides are wound up on the drum shaft B, so that the surfaces of the hides rub one against the other, and when the said shaft is revolved in the opposite direction the hides unwind, again rubbing against one another.

In order to impart motion to the shaft B in opposite directions, the following device is provided: On the ends of the drum shaft B are secured the gear wheels E and E, of which the former is in mesh with a gear wheel F, mounted to rotate loosely on the main driving shaft G, carrying fast and loose pulleys G and G connected by belts with suitable machinery for imparting a continuous rotary motion to the said main driving shaft G. The other gear wheel E is in mesh with an intermediate gear wheel H, in mesh with a gear wheel H, also mounted to rotate loosely on the main driving shaft G. On the inner faces of the gear wheels F and H are arranged the clutch teeth F and H respectively, adapted to be engaged by corresponding clutch teeth I and J respectively, formed on the clutches I andJ respectively, mounted to slide on and to rotate with the main driving shaft G. Springs K and K press on the clutches I and 1 respectively, so as to hold the latter with their clutch teeth in frictional contact with the clutch teeth F and H on the gear wheels F and H. The clutches I and J are engaged by clutch levers L and L respectively, carrying on their free ends frictional rollers 11 and L respectively, traveling on camsNand N respectively, formed on the faces of gear wheels 0 and 0' respectively, secured on shafts P and P respectively, arranged at right angles to the drum A. The shaftsP and P are geared together, and for this purpose the shaft P is provided with a pinion P in mesh with a gear-wheel P secured on the other shaft P. On the shaft P is also secured a bevel gear wheel Q, in mesh with a bevel pin ion Q held on one face of a bevel gear wheel Q in mesh with a gear wheel Q secured on the main driving shaft G. The two cams N and N are so arranged that they alternately actuate the clutch levers L and L, so as to move the clutches I and J respectively alternately in mesh with the respective clutch teeth F and H on the gear wheels F and H respectively.

The operation is as follows: When the main driving shaft G is rotated and the several parts are in the position illustrated in Fig. 1, then a rotary motion is transmitted to the drum A by the gear wheels H, H and E, as

the clutch J has its teeth J in mesh with the clutch teeth H on the gear wheel H. The other gear wheels E and F rotate loosely as the clutch I is out of mesh with the clutch teeth F on the gear wheel F. The drum A now Winds up the hides as previously described, so as to bend them and cause the surfaces of the hides to rub one against the other, and as soon as the drum A has made, say about seven revolutions, then the cams N and N cause the clutch levers L and L to change their positions, so that the clutch J is thrown out of mesh with the gear wheel H, and the other clutch Iis thrown in mesh with the gear wheel F. The drum A is now rotated in an opposite direction, so that the hides unwind and the rubbing of the surfaces of the hides again takes place. The drum A rotates about seven times in this direction, until a change in the clutch levers 'L and L again takes place, by means of their cams N and N, it being understood that the latter are continuously rotated, as their gear wheels 0 and O are in mesh with each other and are driven from the main shaft G, as previously described.

This operation is repeated for the desired length of time, after which the machine is stopped, the hides are taken out of the drum and again inserted with the other side up, and the'above described operation is then repeated; that is, the hides are first wound up on the shaft and then unwound in the opposite direction, as above described. In other words, while the driving shaft rotates constantly in one direction, the drum reverses itself at the end of every seventh revolution, so that the machine is entirely automatic. It will be observed, that the driving shaft is placed parallel to and as near the drum as practicable, and yet allow sufficient intervening space for the reversing gear and cam mechanism. The cams N, N, are also placed so that the clutch levers co-act with them in the most efficient manner, and without occupying space available for other purpose.

Having thus described my invention, I claim as new and desire to secure by-Letters Patent 1. The improved, automatic, reversing ma chine for working hides, composed of the driving shaft, the drum to which the'hides are attached, the two sets of parallel meshing gears F E, and H H E, which operatively connect said shaft and drum, the two clutches and pivoted clutch levers L L, the two geared cams N N, with whose peripheries the free ends of said levers work in contact, and gearing arranged intermediately of and connecting the cams and driving shaft, as shown and described.

2. In a machine for Working hides, the combination, with the drum, driving shaft, clutches, and pivoted clutch levers, of the gear wheels 0 0, having cams, N and N, on their faces, the free ends of said levers carrying rollers that work on said cams, and gearing which connects such geared cams and the driving shaft, as shown and described.
