IMPROVEMENT IN VEHICLE-SPRINGS.

Specification forming part of Letters Patent No. 1

July 28,

To all whom it may concern Be it known that I, Q-EORGE A. RICHARDS, of the city of New London, in the county of ate of Connecticut, seful Improvement and I do hereby declare s a full, clear, and exact el'erence being had to the making part of this specihave invented a new and u in Carriage-Springs; that the following i description thereof, r annexed drawings, fication, in which- Figure l is a perspective view of so much of the running -gear of a vehicle as it is necessary to show for an illustration of my invention. Fig. 2 is a plan of the same. Fig. 3 is an elevation of one of the cross-bars and rockers for connecting the body of the vehicle to the side bars.

The same letters of reference are used in all the figures in the designation of identical parts.

This invention relates to what are termed side-bar vehicles and consists in connecting the body of such vehicles to the side bars by means of rockers secured upon metallic cross-bars clipped to the side bars, the metallic cross-bars, whether made of iron or steel, possessing some elasticity, which, in connection with the rockers, will provide for a pleasant slight rolling or swaying motion of the body on the side bars.

To enable those skilled to mak invention, 1 will proceed to desc its construction and operation."

The parallel side bars A A are, near their ends, secured to the transverse springs B B, which are attached to or connected with the axles O O in the ordinary manner. The mee and use my ribe in detail tallic cross-bars D D are clipped or otherwise fastened to the side bars at some little dis- 1 tance from the springs and axles.

These cross-bars may be made either of iron 85,968, dated January 2, 1877; application filed or steel, care being taken to make them thin enough, so that they may yield slightly under the load of the body, and in response to the jolts to which the vehicle may be subjected.

The crossbars carry on their upper sides rockers E E, made straight on the top side, but curved at the bottom side in a longitudinal direction. Each rocker is firmly secured to its respecti v6 cross-bar by a couple of bolts, 6 0, near the center, as clearly shown. The vehicle-body (not shown) will be firmly secured upon the rockers E E. which may be made of wood.

In the use of these rockers, the horizontal or plain metallic lateral rolling motion is imparted to the body of the vehicle, which renders the same more agreeable to the rider, and, to all intents and purposes, practically adds to the elasticity of the springs. Moreover, the straight crossbars can be made cheaper than the semi-elliptic or curved spring, which is necessary when the rockers are not used.

The direct vertical movement of the carriagebody is derived from the springs supporting the side bars and the lateral springing of the side bars, in connection with the bending of the cross-bars.

What 1 claim as my invention, and desire to secure by Letters Patent, is

The combination of the rockers imparting a lateral rolling motion to the vehicle-body, the side bars, the springs supporting the latter, and the cross-bars attached to the side bars and supporting the rockers, substantially as described.

resting upon cross bars, a
