The box is providedwith a screwfrom the chamber 27 and passing it back to plug l2, which closes an opening employed the chamber 26. A construction of pump suited for this purpose is illustrated in Figs. 5 and 6, in which it will be seen that the pin or axle 2O of the roller 19 is extended into the body of a pump 36 and carries the arms 37 of same, the inlet-pipe 3S of the pump passing into the waste-oil chamber Q7, while the outlet-pipe 39 delivers into the chamber 2G, the pump being operated by the movement of the roller caused by the friction of the axle 9 thereon.

In Fig. 7 is shown the arrangement employed when the axle-box is formed in top and bottom parts 1 2 instead of in one piece. Inthis case the top part 2" is provided with a recess 40 for the vehicle-spring and springbuckle and a recess 41, in which is fitted the bearing 14. It is also provided with a projection 42, which iits into a recess in the bearing 14 in order to take the longitudinal thrust. On the side of the partQ are projections 43 corresponding toprojections 44 or the bottom part 1, and through these projections pass bolts 45, said bolts being provided with the necessary nuts and with springs 13, which act to raise the bottom portion l as the bearing wears, or, in other words, keeps it concentric with the axle as the upperpart 2 falls with the wear of the bearing.

That we claim is* 1. In combination, the axle, a bearing above same, a box inelosing said bearing, means for supporting the bearing, springs exercising a pressure between a fixed part and the box, so that the box is lifted and kept concentric with the axle as the bearing wears, means forearrying the springs and means for counteract ing the upward tendency of the springs, substantially as described.

2. In combination, the axle, 'a bearing above saine, a box inelosing said bearing, springs between the bearing Aand the box so that the box is lifted and kept concentric with the axle as the bearing wears, means for guiding the box, means for supporting the bearing, and a friction roller carried by the box on which the axle bears and adapted to counteract the upward tendency of the springs, substantially as described.

3. In combination,the axle, a bearing above same, a box adapted to hold oil, inelosing said bearing, means for carrying said box, springs adapted to raise said box and keep it concentric with the axle as the bearing wears, a friction roller carried by the box on which the axle bears, for counteracting the upward tendency of the springs, means for carrying and guiding the springs, and means for guiding the box and supporting the bearing, substantially as described.

4. In combination, the axle, abearing above same, a box adapted to hold oil inelosing said bearing, springs between the bearing and the box so that the box is lifted and kept concentric with the axle, a saddle in which the box is guided, means for supporting the saddle, a lug carried by the saddle and passing into the box for supporting the bearing a friction roller carried by the box on which the axle bears, and adapted to counteract the upward tendency of the springs, a partition in the box for forming a waste oil chamber beneath same, and a stuffing box for preventing the escape of oil from the axle box, substantially as described.

5. In combination, the axle, a bearing above same, a box adapted to hold oil, inelosing said bearing, springs between the bearing and the box so that the box is lifted and kept concentric with the axle, a saddle in which the box is guided, means for supporting the saddle, a lug carried by the saddle and passing into the box for supporting the bearing and takin g the longitudinal thrust, means carried by the bearing and engaging with said lug for keeping the bearing in position, a friction roller Carried by the box on which the axle bears and adapted to counteract the upward tendency of the springs, lugs for supporting the friction roller, a spring Vfor keeping saine in contact with the end of the axle, a partition in the box for forming a waste oil chamber beneath same, a stuffing box for preventing the escape of oil from the axle box, and a plate for covering the stuffing box substantially as described.

6. In combination, the axle, a bearing above same, a box adapted to hold oil inelosing said bearing,springs exercising a pressure between a fixed part and the box so that the box is lifted and -kept concentric with the axle as 'the bearing wears, a friction roller carried by the box on which theaxle bears for countei acting the upward tendency of the springs, -a partition in the box for forming a waste oil chamber beneath same, a stuffing box for preventing the esc-ape of oil from the axle box, land a centrifugal pump operated by the revolving axle for lifting the waste oil from its chamber back to the axle box, substantially as described.

In testimony whereof we have hereunto set our hands in the presence of two subscribin witnesses. X
