CAR-AXLE BEARING.

SPECIFICATION forming part of Letters Patent No. 366,315, dated July 12, 1887.

Application filed November 9, 1886 Serial No. 218,423. (No model.)

To all whom it may concern:

Be it known that we, ANDREW JACKSON HAWKINS and J OHNNVALKER WILKINs, citizens of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented a new and useful Improvement in Combination. Axle and Oil-Box for Railways, Street-Oars, and other Machinery, of which the following is a specification.

Ourinvention relates to an improvement in ear-axles and bearing-boxes therefor; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is an elevation of a portion of a caraxle, the bearing-box being shown in transverse section. Fig. 2 is a vertical sectional view taken on the line mm of Fig. 1. Fig. 3 is a perspective view of the bearing-box.

A represents the car-axle, the outer end of which, beyond the outer side of the wheel B, is enlarged to form an annular collar, 0. A suitable space is left between the inner side of the said collar and the opposing outer side of the wheel. The collar is provided with a peripheral annular groove, D, thereby forming flanges E on the'sides of the said groove.

F represents the bearing-box, comprising the upper section, G, and the lower section, H. The said sections are secured together by means of bolts I and metallic straps K, which are fitted in'grooves that are made on the upper and lower sides of the box. Between the opposing edges of the sections G and H, on

one side thereof, is made a circular opening, L, the diameter of which exceeds the diameter of that portion of the axle between the collar 0 and the wheel. In the upper side of the upper section of the box is made a recess, M, to receive the block N, the under side of which is concave and bears upon the upper side of the groove 13 of the annular collar. In the outer side of the box is made an opening, 0, through which oil may be supplied to the box. Enough oil ispoured into the box to partly submerge the lower side of the annular collar of the axle, so that as the axle rotates the oil will be taken up by the annular collar, and thus the oil will become diffused over the face of the collar and the bearing-face of the block N, so as to thoroughly lubricate the axle and prevent the same from becoming heated.

As the opening L through which the axle enters the box is larger than the axle, it follows that there is no friction between the axle and the sides of the box, the only friction being between the collar 0 and the bearingblock N.

The collar 0 is preferably made separately from the axle, and is shrunk on the end of the same. By this construction the collar may be removed from the axle and replaced by a new one after it has become worn, and the bearingbloclc N may also be renewed from time to time, thus preventing wear on the axle and adding greatly to the durability both of the axle and of the bearing-box.

Having thus described our invention, we clain1- V i 1. The car axle box comprising the separable upper and lower sections having the 1011- gitudinal grooves on their respective upper and lower sides, the straps K, fitting in the said groove, and the bolts I, engaging the said straps and clamping the sections of the box together, substantially as described.

2. The combination of the box comprising the separable upper and lower sections, and having the opening L in one side, formed in the opposing edges of the separable sections, with the axle extending through the said opening, and the block N, bearing on the said axle and located in the box, substantially as de scribed- 3. The box composing the separable sections, in combination with the axle having its end fitting within the box, the collar shrunk onto the end of the axle within the box, said collar having the annular flanges, and the block pressing on the coll-a r within the flanges, as set forth.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
