To all 11/71/0121, it may con/corn.-

Be it known that we, JOHN \VILLIAM SiIrInRD and JollN DONE, of Blackpool, in the countyof Lancaster, England, have invented certain new and useful Improvements in Bearings, (for which we have already obtained Letters Patent of Great Britain, dated August Patent of the April 27, 1896, and numbered 52,109,) of which the following is a specification, reference being had to the accompanying drawings, forminga part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to bushings or linings for Wheels, cylinders, journal-boxes, pulleys, &c.; and it consists of a number of small segmental pieces orstrips of iron, steel, brass, gun-metal, bronze, or any other metal or composition oi. metals made up into the required form or forms, as hereinafter described.

The invention is l'ullyi'loseribed in the following specification, oi. which the accompanying drawings form a part, in which l igureJ is a transverse section of a pulley provided with our improved. bushing or lining; and Fig. 2, a longitudinal sectional view thereof, taken on line 2 2, Fig. 1'.

Our improvement dill'ers from the ordinary bushing consisting of masses or similar devices in that the brasses are done away with and the segmental pieces are placed around the shaft or in the bush ol' the pulley-wheel or cylinder, the segments forming a'more or less broken circle or annulus and one or more cmployei'l, where required, though not in all cases, to keep the segments in position.

Referring to Fig. 1 of the drawings, A designates the body or hub ,of a pulley, and 'B the segmental sections of our improved bushing, all of which segments are substantially uniform in cross-section and each free and indepcndentotthe others and having smooth adjacent edges adapted to come in tree contact with the edges of the adjoining strips, 0 0 being longitudinal recesses for oil, employed or formed where andjwhcn necessary and preferably on both ING.

11,630, dated September 21, 1897 reissue filed May 20,1897. Serial No 637,415. Patented in and in Canada April 27, 1896, No. 52,109.

the inner and outer sides of the bushing or lining.

Theannular col lar orccntripelal projection (shown in Fig. i?) designed to keep the segments from working out or moving longitudinally, and a band E is also preferably employed to keep the segments in position when filling. p

The longitudinal recesses '(J for oil or other lubricant are also shown in Fig. 2, and

a smallopening or perforation F ing thelubrirant from thcouter surface of the bushing, it being understood that these recesses C and the small opening are in communication with passages or perforations in the body or hub A of the pulley in the usual manner, as indicated at G, through which the oil may be supplied in the customary way.

In the case of an ordinary bearing the inside of the pedestal, cylinder, or other body. can be bored out and faced to provide a recess for the segments, or the segments can be litted to any style of ordinary bearing, and the raised annular i) keep the segments in position, and in the case of a loose pulley or similar device the segmental piecesform the bush or hearing and are held in place by an ordinary collar, and when the shaft or loose the friction will cause the segmental pieces to revolve also, but at a much slower speed.

The combined cireumferenl ial width of the segmental strips B is such as not to comfor conveyto the inner pletely line the pedestal or form a complete 85 annulus or circle, but so as to leave a space or clearance between them which serves to prevent them from binding and enables them to'act freely. By this construction when a shaft is mounted to revolve within the pedo estal the friction between it and the segmental strips 13 will cause the latter: to l evolve also, but at much less speed.

hat we claim is as follows: 1. A bushing for pulleys, wheelsinders, consisting of a series of segmental strips, each free and independent of the others and adapted to be held endwise in place, but so as to be free to rotate about the shaft or other body against which they bear, with mo projections or shoulders pulley revolves So means for so confining said strips, substantially as herein described.

2. A bushing forQpu lleys, wheels and cylinders consisting or a series of segmental strips, each free and independent of the others and having smooth adjacent edges adapted to come in free contact with the edge of the ad joiningstrips, and all held endwise in place and free to be rotated about the shaft'or other body against""whichthey teat-with means for so confining said strips, substantially as described.

3. A'bushing for pulleys, wheels, and cyl inders, consisting of a series of segmental strips all substantially uniform in cross-secfion and adapted to freely rotate about the shaft or other body against which they bear, and'each strip having smooth adjacent edges adapted to come in free contact with the edges of the adjoining strips and being of such transverse widththat the combined circumferential'width of the series will not completely surround said shaft, and means for retaining the strips endwise against longitudinal displacement, substantially as shown and described.
