CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 232,149, dated September 14, 1880. Application filed April 24, 1880. (No model.)

To all whom it may concern:

Be it known that I, EDGAR RoBINsoN, of Columbus, in the county of Franklin and State of Ohio, have invented a new and valuable Improvement in Oar-Axle Boxes; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a longitudinal vertical section of my improved car-axle box. Fig. 2 is a transverse section of the same. Fig. 3 is a top view of the same, with the equalizer in section; and Figs. 4 and 5 are perspective views, respectively, of the lower and upper bearings.

This invention has relation to car-axle boxes; and it consists in the construction and novel arrangement of parts, as hereinafter shown and described.

In the accompanying drawings, the letter A designates the case or body of thecar-axle box, the sides of which are connected by a transverse bridge or bearing, B, having a spring connection or catch, a, which engages a lug, I), on the upper surface of the cover O, which slides into the case from the outer or front end freely under the bearing B, its sides 0, which are preferably beveled, working in slide= grooves din the upper portions of the sides of the box.

The front of the cover G is made with side guides, D, and a slidegate, E, designed to be raised when it is desired to inspect the interior of the box. To this gate is secured an angular springcatch, c, which engages with. the front end of the cover and holds the gate down. The end of this spring passes through an openin g, f, in the gate, and serves as a handle whereby the catch can be released and the gate raised, when the spring, returning to its position, will hold the gate up by its engagement with the upper edge of the front of the cover.

In the lower portion of the box is the oilcavity F, having extending into it a spindle, g, on the end of a spring, g, or other form of spring-bearing connected to the inner portion of the box, to receive the oil-roller k, which is arranged to slide on the spindle toward the front of the box, to allow the splash-box G, which covers the oil-cavity under the journal, and which has an opening, I, through which the roller works against the journal H, to be readily removed when necessary.

From the lower part of the inner end of the box extends upward, under the axle, a semicircular flange, m, raisingthe inner boundary of the oil-cavity to, or nearly to, the axle, and thereby increasing its capacity, as well as preventing undue leakage at this end of the box, which is apt to occur when an open space is left under the axle in the margin of the box, as is commonly the case when the box is raised bodily in releasing the brasses. Above this flange is the inner slide-plate, K, which closes the inner end of the box over the journal. Outside of this plate, and through the inner ends of the side walls of the box, from points a little below the level of the top of the journal, are arranged vertical transverse slots or bearings s, which receive a transverse wedge, L, which extends across the axle, bearing on the same, so that when it is desired to release the cover and brasses from the pressure above it is only necessary to insert this wedge and strike its larger end a smart blow.

R indicates the upper or outer brass or bearing, which is next the cover of the box, lying underneath the same and upon the lower brass or journal-bearing, T. These brasses are usually provided with vertical guides n, which keep them in position, the upper ends of these guides being sufficiently below the bridgebearing B of the box to allow the Masses to be raised clear thereof and withdrawn when the sliding cover has been removed. The up; per brass, R, is made with a downward flange, 1', serving as an inner guard or abutment.

Having described this invention, what I .claim, and desire to secure by Letters Patent,

1. The combination, in a car-axle box, with the transverse bearing B and its catch a, of the sliding cover 0 and its catch-lug 1), substantially as specified.

2. The combination, with a car-axle box and its wedge-bearings s, of the transverse liftingwedge L, adapted to bear on the axle, substantially as specified.

3. In a car-axle box, the combination, with the side walls having slots for a wedge over the inner journal-aperture, the sliding top or cover C, and the oil-chamber F in the bottom part, of the semicircular oil-flange m, extending upward to the journal, serving to transfer the bearing from the upper to the under side of said journal when the brasses are to be removed and to prevent the undue escape of oil, as shown and described.

4:. In a car-axle box, the removable splash box G under thejournal, and having an open ing, Z, in combination with the sliding oil-roller 7c and its spring-bearing, substantially as specified.

5. The combination, with the top of an axleboX and the sliding gate E, of the angular spring catch 0, extending by its free end through the gate and serving to hold the latter either down or in the raised position, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
