SPECIFICATION forming part of Letters Patent No. 729,569, dated June 2, 1903. I

Application filed time 11, 1900.

- To all whom it may concern:

Be it known that I, JEROME R. GEORGE, a citizen of the United States, and a resident of Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Carriers for the Top Rolls of Rolling-Mills, of which the following is a specification, reference being had to the accompanying drawings, forming a part of the same, in which Figure 1 represents a top view of a rollingmill housing with the upper roll removed and the housing shown in sectional View on line 1 1, Fig. 2. Fig. 2 is an end View with aportion of the housing broken away for the purpose of showing the screw for tightening the roll-carrier. Fig. 3 is a perspective view of the actuating-wedge by which the roll-carrier is pressed against the gudgeon of the roll.

Similar reference-letters refer to similar parts in the diiferent views. 7

My invention relates to a carrier or support for the gudgeon of the upper roll of ,a rollingmill by which the weight of the upper rollis 2 5 supported and the roll held in' proper operative position relatively to the lower rollfand it consists in providing a bearing-surface beneath the gudgeon of the upper roll by the employment of a pair of blocks inserted hego tween the gudgeons of the upper and lower rolls and crowded apart, so as to press the lower block of the pair against the gudgeon of the lower roll and the upper block of the pair against the gudgeon of the upper roll 3 5 and support the weight of the upper roll.

Referring to the drawings, A A represent the housings of a rolling-mill containing a lower roll B and an upper roll C, having gud-- geons B and C at opposite ends of the rolls,

40 the gudgeons B of the lower roll resting in bearings B in the housings. Between each" pair of gudgeons B and C, I placetwo blocks D and E, preferably of wood. The block D is beveled 'at one'end and on its upper side.

at D, and the block E is similarly beveled at one end and on its under side at E, forming a triangular opening at one end of the blocks to receive a wedge F, provided at its center with a screw-threaded opening F to receive ;a metal cap-block resting upon the gudgeon 1 of a wedge located directly beneath the axis My improved top-roll carrierconsists, prefthe screw-threaded end of a bolt G, which is Serial No. 19,949- (No model.)

supported in the housing and is provided with a collar G, held in a recess G in the housing, by which the bolt Gis held from longitudinal movement. The end G of'the bolt is squaredto receive a wrench, by which the bolt may be rotated and the wedge F forced between the beveled ends of the blocks D and E by the action of the screw-thread. The blocks D and E when placed between the gudgeons B and C nearly or quite fill the space between the gudgeons, so that a slight movement ofthe wedge Fin forcing the blocks D and'E apart at one end will crowd the blocks together at their opposite ends and carry their central sections against the gudgeons of the upper and lower rolls. The blocks serve as-levers, with their contacting endsheld from movement and acting as fulcra, which are located entirely at one side of the vertical plane containing the axes of the 7 rolls, and the pressure of the wedge against the beveled ends of the blocks on the opposite side of said vertical plane will press the upper block against the gudgcon C of the upper roll and the lower block against the gudf'geon B of the lower roll, thereby spreading the blocks apart and supporting the weight ;of the upper roll.

It has been customary heretofore to employ of the lower roll and a carrier-block supporting the gudgeon of the upper roll, said carrier-block fitting the gudgeon and being capable of a direct vertical movement by means 5 of the upper roll and acting against oppositely-inclined surfaces on the cap-block and carrier-block; but I do not claim such a c011- struction.

9O erably, of a wooden block having parallel sides adapted to bear against the gudgeon of the upper roll and having a short beveled surface at one end to receive the contact'of the wedge,while the opposite end is held from 5 movement, thereby serving as a fulcrum on which the block is rocked by the action of the wedge. As the beveled ends of the blocks are free to move, the wedge is capable of being held upon the screw-threaded end of the mo bolt or shaft journaled in the roll-housings, whereas by the usual construction of wedgeaetuated top-roll carriers provision must be made for the vertical movement of the wedge as it slides upon the inclined upper surface of the lower or cap block. The actuatingwedge F is a short wedge entering but a short distance between the ends of the blocks D and E. The opposite or contacting ends of the blocks D and E are free to move up and down within the housing, so that the rolls may be adjusted vertically in the housing without requiring a readjustment of the actuating-wedge, the rising or falling motion of the rolls imparting a slight rising or falling motion to the contacting ends of the blocks D and E.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. The combination with a rolling-mill housing and a pair of rolls held therein, of means for supporting the upper roll of said pair and consisting of a block resting upon the gudgeon of the lower roll, a block bearing against the gudgeon of the upper roll with one end of the upper block in contact with the corresponding end of the lower block and means for separating the opposite ends of said blocks, whereby the lower block is crowded against the gudgeon of the lower roll and the upper block is crowded against the gudgeon of the upper roll, substantially as described.

2. The combination with a rolling mill housing and a pair of rolls held therein, of means for supporting the upper roll of said pair and consisting ofablock resting upon the gudgeon of the lower roll, a block placed beneath the gudgeon of the upper roll with one end of said upper block in contact with the corresponding end of the lower block, with the contacting ends of said blocks held in a free space within said housing whereby said contacting ends are capable of a vertical movement as the rolls are adjusted vertically, and means for separating the opposite ends of said blocks, substantially as described.

3. The combination with the gudgeons of the upper and lower rolls of a rolling-mill, of

a carrier for the top roll comprising a pair of blocks placed one above the other and between the upper and lower roll gudgeons, each of said blocks having a beveled surface at one end, a wedge inserted between said beveled surfaces and means for actuating said wedge to support the beveled ends of said blocks while their opposite ends are held from vertical movement, thereby raising the upper of said blocks against the gudgeon of said upper roll, substantially as described.

4. The combination with a roll-housing and a pair of rolls held therein, of means for supporting the upper roll of said pair of rolls and consisting of a pair of blocks one above the other and inserted between the ends of the upper and lower rolls, said blocks having op posing beveled surfaces at one end with their opposite ends held in contact, a wedge in serted between said beveled surfaces and provided with a screw-threaded hole and a bolt journaled in said housing and held from longitudinal movement, said bolthavinga screwthreaded end engaging said wedge to force it between said blocks, substantially as described.

5. The combination with a roll-housing and a pair of rolls held therein, of means for supporting the ripper roll of said pairs of rolls and consisting of a pair of blocks inserted one above the other between gudgeons of the upper and lower rolls, said blocks having short beveled surfaces at one end with their opposite ends in contact, a wedge inserted between the beveled surfaces of the blocks, and means for forcing said wedgev between the blocks.

In testimony whereof I have signed my name to this specification, in presence of two subscribing witnesses, this 1st day of June, 1900.

JEROME R. GEORGE.
