Specification forming part of Letters Patent No. 49,942, dated September 12,1865.

To all whom it may concern.-

Belit known that I, LEVI H. WEST, of Cambridge. in the county of Middlesex and State of Massachusetts, have made a new and usefol inventionlhaving reference to Street or Horse Rail-wayCarsfor Carriages; and I do hereby declare the same to be fully described shown and described in the specification and drawingsot' the three Letters Patent of the United States numbered 38,726, 44,278, and 47,143, the first and second of which were granted to Alfred Bridges and the third to True \Vest, for in neither of the carriages described in such specifications do we find levers and springs arranged with reference to the truck-frame and the platform, in manner as hereinafter described.

In the said drawings, Figs. 1, 2, and 3, the

.platiorm-iranie ot' the car or carriage body is represented at A and the truck-frame at B. The said truck-frame has two axle-boxes, aa, on each side of it, which are fixed within and niah-e part of it. These boxes receive in the ordinary manner thejournals of the next adjacent wheels, C C. Underneath each side of the platform are two levers D D, whiclrat their inner ends bear on the truck-frame and directly over the boxes a a. The fulcra Z) Z) of these levers aresupported by the platformi'rame and are arranged with reference to the truck-frame, in manner as shown in the drawings. rod, 0, passes through and upward from the outer end of each lever and through the platform-frame and a banspring, E, or .iirough the same and a cylindrical spring, F,

such rod being suspended from the top of the spring by having a head to bear on a capplate, (1, resting on such spring.

7 The auxiliary or bar spring may be dispensed with and the rubber spring be made to rest directly on the platform instead of on the bar-spring.

At the fulcrum of each'lever there is a projection, f, which enters a corresponding hole, 9, made in the bearing h of the lever. Fur thermore, the said bearing is provided with. lipsi i, to extend from it and down a short distance alongside of the lever, the same beiu g as exhibitedin Fig. 2, and also in Fig. 4.,which is a transverse section of the lever and hearing. There is also at the bearing of each lever D on the axle-box a projection or pin, le -which goes across the box and enters a corresponding recess, 1, made in the lever, the whole being to keep the lever in placeagainst the axle-hex and platform-frame.

By my arrangement the springs are disposed above the platforin-frame and comeinto the space that is underneath the side seat of the car. In this way they are completely protected from snow, ice, dirt, or water when raised by and thrown from the wheels. W hen the springs are underneath the platform they are more or less exposed to snow or water thrown on them by the wheels. Such snow or water, when frozen on them, will more or less impede their action. Other important advanvagcs of my arrangement will be easily perceptible to persons skilled in the art to which it appertains.

I do not claim either of the inventions described in the aforementioned patents; but

I claim as my invention or improvement- The arrangement of levers D D and the spring or springs of each with the platform frame A and the truck'fraine B, the same be ing substantially as and so as to operate as specified.
