FRICTION-BEARING.

SPECIFICATION forming part of Letters Patent No. 311,925, dated February 10, 1885.

Application filedAugnst 13, 18*4. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE W. SHOEMAK- ER, a citizen of the United States, residing at Dalton, in the county of Lackawanna and State of Pennsylvania, have invented new and useful Improvements in Friction Bearings, of which the following is a specification, reference being had to the accompanying drawings.

My invention has relation to friction-bearings forjournals of axles designed to be used without lubricators; and it consistsin the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings, Figure l is a vertical longitudinal sectional view of a portion of an axle with my improved friction-bearing applied thereto. Fig. 2 is a vertical transverse seetion on the line a; w in Fig. 1, and Fig. 3 is a vertical sectional view on the lineyy in Fig. 1.

Referring by letter to the accompanying drawings, A designates a straight untapering axle, having collar 0 made integral therewith or secured thereon, and a collar, 0, near its outer threaded end, D,which is removahly The collars O and C are grooved in their opposite faces to receive the ends of the alternating rolls B and B. The ends of the rolls B are tapered to form cen ter points. E. which fit the flaring mouths E of the groovt s FF of the collars C C. The ends of the rolls B are nntapered and enter the deeper parts F of the grooves F F. The rolls B are covered with rubber or other elastic substance, and keep the surfaces of the rolls B from touching each other. The rolls B are case-hardened, as is also the pipe or sleeve G. The sleeve G is slipped over the rolls B B, and is held in place by a flanged nut, H,which is turned on the threaded end of the axle A. The axle A has a seat, I, turned in it for the reception of an elastic band, J, which springs out against the rolls B to prevent chattering. The grooved collars O 0 hold the rolls together when the sleeve G has been removed.

No oil or other lubricator is required with axles provided with these friction-bearings. They run perfectly dry and radiate the heat as rapidly as it is generated, and are therefore comparatively cool when operated.

Having thus fully described my invention. what I claim as new, and desire to secure by Letters Patent of the United States, is

The combination, with the untapered axle having threaded ends and the collars O O, grooved in their opposing faces, as at E F, of the case-hardened rolls B, having tapering ends E, the rolls B, having elastic surfaces and nntapered ends, the elastic band J in a seat in the axle, the case-hardened sleeve G, and the flanged nut H, substantially as specified.

In testimony that I claim the foregoing as my own I havehereto afli xed my signature in presence of two witnesses.
