UNITED STATES PATENT OFFICE.

BERNARD J. LA MOTHE, OF NEW YORK, N. Y., ASSIGNOR TO THE UNITED STATES ROLLING'STOOK COMPANY, OF SAME PLACE.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 402,169, dated April 30, 1889. Application filed August 30, 1888. Serial r01 284,194. (No model.)

Be it known that I, BERNARD J. LA MorHE, of the city and State of New York, have invented an Improvement in Oar-Trucks, of which the following is a specification.

Previous to my invention car-trucks have been provided with wheels, each upon a separate axle, and the frames of such trucks have been made of plates of cast and Wrought metal, and also of wood and metal combined.

In .my present invention I make the truckframe of rods and tubes of metal, the side frames being made of rods and the end frames and transom of tubes; but the side frames are each made of two parts, so as to receive the car-wheels between the two parts of the frames. The car-wheels are each upon a separate axle and the boxes for the axles are supported by the rods of the side frames, as hereinafter set forth."

In the drawings, Figure 1 is a plan of my improved car-truck. Fig. 2 is a longitudinal section of the same at the line x 00 of Fig. 1; and Fig. 3 is a section of the line y y of Fig. 1, with the car-wheel and its axle in eleva tion.

The truck-frame is somewhat similar to that shown in my application for patent of like date herewith, the side or longitudinal frames being composed of two ranges of metal rods, (1 a, preferably of steel, and the transom is made of two ranges of tubes, 1), also of steel, with the rods of the side frames passing transversely through the transom-tubes; but the side frames are made in two parts, a b, so that the car-wheels h are between the two parts of the side frames, and there are tubes '0 c, forming end frames to the truck, and through these tubes 0 the rods a a pass transversely, and nuts f upon the ends of said rods a a confine the tubes 0 c in place.

0' c are bands passing around the tubes 0 c, to keep said tubes from spreading, and o is a band passing around the transom-tubes b b, to keep them in their proper position at the center of the truck.

The rods a a pass through the journalboxes d d and support said boxes, and there "are tubes e 6 around the rods a between the journal-boxes and the tubes 0 and also be- ,tween said boxes and the transom-tubes b, av kthere are bands 6' around each group s a between the tubes 6 b, and these able that said bearing tubes and bands prevent the journal-boxes and transom-tubes moving upon the rods (1 length, and it projects the same distance from opposite sides of the wheel, and each end is provided with journals Z. The bearings for the journals Z may be of usual character and be supported within the journal-boxes d d in any desired manner;

It be slightly shorter than the journal of the axle, so that the wheel and its aXle may move slightly endwise in said bearing to allow the wheel to accommodate itself to any irregularities in the align- 7o ment of the track.

By passing the rods of the side frames through the journal-boxes, as shown, and employing tubes around the rods and between the journal-boxes and the end frames and 7.5

transonrtubes, saidv journal-boxes cannot move upon said rods, and bolts and nuts for securing said boxes to their supporting-rods are dispensed with.

This truck-frame is very strong,but few nuts are required to hold the parts of it together, and said frame, being composed of steel rods and tubes, will spring slightly under strain which would break or bend an ordinary frame of cast metal or cast metal and wood.

I claim as my invention- The combination, with the car-wheels and their axles and journal-boxes, of the four groups of longitudinal rods a a, passing through and supporting said journal-boxes, go

the rods being arranged in two groups at each side of the truck, with the wheels between the respective groups of rods, the transom-tubes I), supported by said rods of the side frames,

the end frames, 0, and the tubes 6 and bands 6 around said rods for keeping the parts of the truck-frame in their proper positions, substantially as and for the purposes specified.

Signed by me this 20th day of August, 888.

B. J. LA MOTHE.
