E. J. HAMILTON, OF CHICAGO, ILLINOIS.

Specification forming part of Letters Patent No. 37,814, dated March 3,1863.

To all whom it may concern,-

Be it known that I, R's-J, HAMILTomfoi the city of Chicago and county of Cook, i'n'the State of Illinois, have invented a new and useful Improvement in Oil or Journal Boxes for Oar-VVheels; and I hereby declare that the following is a full, clear, and exact description thereof, reference being hadsto the acco1npanying drawings and letters and figures I ures.

The views shown in Figs. 1', 3, and 4 are taken from the end nearest to the wheel marked W in Fig.2.

The nature ofmy invention consists in a device or devices to economize or prevent the waste'of oil used in lubricating the journals and the supports thereof of the axles of carwheels. 7

To enable those skilled in the art to understand and construct my invention, I will proceed to describe it with particularity B represents the axis of the wheels, D and j E the supports of the journal, and H the chamber to contain the oil. 01, whose position is shown in Fig. 3 by the dotted linesd d d (1, represents a fixed stationary collar, which fits about, and upon which rests, the axis or journal.

A represents a similar movable collar, which is adjusted to the journal by means of the spring a beneath it, and also to the support marked S in Fig, 2.

Q represents a washer, of leather or other suitable material, which is fitted about the journal within a icirculargroove made in the supports D E. This washer is cut asunder at b diagonally or obliquely, so that each part has a sharp edge or lip to facilitate the ends passing by each other uponpressure applied. Beneath G is placed the spring 0, which operates-in a similar manner to the spring a.

- Thenature of my invention consists in having the adjustable collar A placed upon the spring a, so that when the, bearings and supports become worn by use and the journal recedes from the fixed collar d, the spring a will cause the adjustable collar A to follow up and continually press against the journal and the support S, thereby preventing the oil which passes or runs over the fixed collar d to escape.

Myinventiou consists, further, in having the diagonal or oblique cut made in the washer U, 1 (shown at 1),) and in having the springc placed beneath, as shown in Figs. 1', 2, and 3, so that when the bearings and supports become worn as aforesaid and thejournal recedes from below the spring 0 will press the washer up against said journal, making the washer assume the position and form as represented by the dotted lines a c in Fig. 4, the edge b passing by to b, thuspreVenting the ingress of sand and dust into the'box.

f and g are openings through d and E to al low any oil that may by any chance escape to pass back into the oil-chamber ll.

I claim as my invention- The combination and arrangement of the adjustable collar A and the washer 0 when out as described, and both are operated upon and used with the springs 11 and c, or their equivalents, and the openings 9 and f, when all are arranged and operating substantially as and for the purposes delineated and set forth.
