LEATHER-ROLLING MACHINE.

Specification of Letters Patent.

Patented June 1 1, 1907.

Application filed June 27,1902. Serial No. 113,486.

To all whom it may concern:

Be it known that I, GEORGE ARTHUR SGHIEREN, a citizen of the United States, and a resident of Bristol, in the county of Sullivan and State of Tennessee, have invented certain new and useful Improvements in Leather-Rolling Machines, of which the following is a specification.

My invention relates to rolling machines.

More particularly stated the object of my mvention is to produce a rolling machine for leather which is self-adjusting for wear; yielding to irregularities of stock; compact and not liable to get out of order or alinement; under easy control of the operator; without jar or sudden strain upon its oper ating parts; presenting an entire absence of rubbing, and which will roll wet leather as well as dry.

For this purpose my invention consists in the following combination and arrangement of the parts, the details of which will first be fully described, and. the features of novelty then set forth and claimed I Figure 1 represents a side elevation of a machine to which I have applied my improvements. Fig. 2 is a front elevation thereof. Fig. 3 is a rear elevation of the machine. Fig. 4 is a top plan view of the machine, showing parts thereof in horizontal section.

In the drawings 1 represents the bed-plate of the machine.

2 is a rigid frame of the Q-shaped type presenting two oppositely projecting jaws 3 and 4, between and upon which the main rolls of the machine are carried. The lower jaw carries an open bearing 5 in which is hung an oscillating yoke frame 6 which oscillates thereon in a line transverse to the length of the machine. Yoke 6 carries bearings 7 within which is mounted the shaft 8 rotated by the driving mechanism of the machine. Shaft 8 carries the lower roll 9 splined or otherwise secured fast thereto.

The rotary shaft 10 is in line with the shaft 8, and rotating therewith, and is provided with a gear 12 at the rear of the machine, the two shafts 8 and 10 being connected by a universal or knuckle joint device 11 which permits the shaft 8 to be driven by the counter-shaft 10, and at the same time to yield in predetermined limits in any direction. Geared to the counter-shaft by gear wheels 12 and 13 is another counter-shaft 14. which drives the upper roll 15. Roll 15 is carried in the upper jaw 3 in bearings 16.

The main driving shaft 17 is carried in a tail extension 18 of the frame 2 and turns in bearings 19. Upon the shaft 17 is a pinion 20 which gears with the intermediate gear 13 transmitting motion in its turn to the gear 13.

21 is the fast pulley on the driving shaft 17, and. 22 and 23 are loose pulleys upon either side of fast. pulley 21. adapted to drive the machine, and to reverse the direction of the rolls and to stop the machine. 24 are belt-shifter devices by means of which these operations are performed and are on either side of the machine.

The lower jaw 5 of the frame 2 is pivotal in character, 2:) being the pivot bearing upon which the jaw has a vertical oscillation. Yoke 6 is carried in the outer end of this jaw, the jaw, in this instance, consisting in part of two long lever arms 26 and 27 pivoted at' 25, the rear ends of which are extended and. provided with weights 28, said weights acting to force the ja and its yoke 6, carrying the lower roll 9, constantly upward and in contact with the upper roll 15.

It will be noted that the lower roll 9 has an oscillating vertical movement upon the pivoted arms 26 and 27 and a horizontally oscillating movement upon the yoke 6 and its bearings 5, the roller itself acting as a yielding bed.

The two rollers 9 and 15 have the same peripheral speed, which prevents rubbing. A uniform pressure is given to the leather by means of the universal adjusting action of the lower roll and its driving mechanism. It will be apparent that the location of these rolls might be reversed or that the yielding character of the lower roll might be imparted to the upper roll or the characteristics of each reversed. The edges of these rolls are rounded in order to prevent distortion of the leather or other irregularities which might otherwise be produced by square-edged rolls. It is also obvious that springs might be substi tuted for the weights herein shown and de scribed. A different system of driving gearing may be substituted within the repertoire of the well-known driving gear art. Any other well-known form of universal joint other than the knuckle joint shown might be adapted.

variations, and at the same time of uniformly the other roll so that it may rock in the same 35 represents a yielding support of any known type for supporting the inner end of the axle 8.

29 is the operating table mounted upon the projecting supports 30 carried by the frame 2, the lower roll preferably passing through a slot in the table and projecting slightly above the plane thereof.

31 are treadle levers pivoted at 32, and having links 33 pivoted to the treadle levers and to the pivoted arms 26 and. 27. The operator by stepping upon the treadle board 34 connecting treadle levers 31 slightly may raise the weights 28 and relieve the pressure of the lower roll against the upper roll. When the treadle board is released the Weights automatically and constantly restore the pressure. Any degree of pressure is secured by adding to or taking away the power of the weights 2S. 4 I

The bearings 25 carry all the pressure and Weight of the rocker bearing and roller bed mechanism.

The leather or other material to be rolled is placed upon the table 29 which facilitates the handling of the stock in the machine.

The double oscillating mounting of one of the rolls is desirable in a machine of this class, as, on account of the constantly varying thickness and inequalities of the hides rolled, it is necessary to apply the pressure througl'r a member capable of accommodating such.

compressing all parts of the hides.

IVhile I have described my invention in connection with a single form of machine exemplified in the accompanying drawings, yet I do not wish it understood that I limit myself to the details of construction of said machine, or to the modifications hereinbefore referred to, as I wish it understood that my invention contemplates any form of machine which comes within the scope of the following claims.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of two rolls, fixed bearings for one roll, a frame swinging in the plane of the axes of the rolls, bearings movably mounted on said frame and. supporting plane as the frame, and means for rotating the rolls.

2. The combination of two rolls,fixedbear ings for one roll, a frame swinging in the l plane of the axes of the rolls, bearings movably mounted on said frame and supporting the other roll so that it may rock in the same plane as the frame, a shaft for the first roll, a flexible shaft for the second roll, and means for rotating the shafts.

3. The combination of a standard open at one end, a roll carried in fixed bearings in the standard, bearings mounted in a swinging frame carried by the standard, oscillating bearings carried by the swinging bearings, another roll mounted in the bearings last mentioned, a shaft for driving said roll, a yielding support for the shaft adjacent to the roll, a flexible part interposed in the shaft, and means for driving the rolls.

4. In a leather rolling machine, the combination of a standard open at one end, two rolls, fixed bearings for one of the rolls, a frame supported by a pivot on the standard so that it swings in the plane of the axes of the rolls; a roll-supporting yoke resting in bearings in said frame and capable of rocking in the same plane as the frame, a shaft carrying the'other roll, and. bearings in. the yoke for said shaft. 1

5. In a leather rolling machine, the combination of a standard open at one end, two rolls, fixed bearings for one of the rolls, a frame supported by a pivot on the standard. so that it swings in the plane of the axes of the rolls; a roll-supporting yoke resting in hearings in said frame and capable of rocking in the same plane as the frame, a shaft carrying the other roll, a universal coupling in said shaft, a shaft in the fixed roll, and means for driving the shafts.

6. In a leather rolling machine, the combination of a standard open at one end, two rolls, fixed bearings for one ofthe rolls, a frame supported by a pivot on the standard so that it swings in the plane of the axes of the rolls a roll-supporting yoke resting in bearings in said frame and capable of rocking in the same plane as the frame, a shaft carrying the other roll, a universal coupling in said shaft, a yielding support for the shaft near the roll, a shaft for the fixed roll, and means for driving the shafts.

In testimony whereof I have affixed my signature in the presence of two witnesses.
