i IMPROVEMENT IN VEHICLE-PLATFORM SPRINGS.

Specification forming part of Letters Patent No. 182,488, dated September 19,1876; application led June 27, 1876.

To all whom it may concern Be it known that I, J osEPn E. SHEREEY, of the city of Brazil, in the county of Clay and State of Indiana, have invented certain new and useful Improvements in Wagon- Platforms; and I do hereby declare that the following Ais a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangement of a platform and beds or bodies for spring wagons or carriages, as will be hereinafter more fully set forth.

In the annexed drawing, Fig. 1 is a plan view, Fig. 2 is a side elevation, and Fig. 3 is a rear view, of my invention.

The object of my invention is to dispense with the use of the cross-spring and shackles as ordinarily used back of the axles, substituting in their place two half-springs, A A, fastened to the lower springs B B in the usual manner, back of the axle C, and fastened at the top to a spring bar or bars, D, of the wood'- work of the platform. This spring bar D extends from spring to spring under the fifthwheel E, and is braced at or near each end by a cross-bar, G, with the front spring-bar D. The springs may be set at right angles with the large spring-bar D and axle, or they may be drawn together in front to any angle required, making the front spring-bar D shorter than the large spring-bar D. The springbar D is also braced and strengthened by one or more iron rods, a, fastened in any suitable manner to its ends, and drawn downwand underneath it, as shown, forming a solid brace.' The hounds H may be fastened either above or below the spring-bar D, or the bar may be made of two dat pieces of springy wood fastened together at the ends, and sprung apart far enough in the center for the hounds to be fastened in between them. The spring-bars D, Gr, and D may be connected in any suitable manner.

To the under side of the upper springA is attached a rubber supporter, d, by means of a bolt, e, extending down a short distance with a swell or head on the end, so that when forced into the cavity of the rubber it will be connected together by means of a shackle, I,

which may be formed by extending the bottom leaf of the upper spring, or it may be made of a separate plate, as shown. The end ofthe shackle, which connects with the front end of the bar Gr, is bent in S or similar form, so that when a heavy weight comes on the spring it will be moved forward as the springs come together, thereby keeping the centers of the spring 4exactly over each other. This arrangement will Vnot be necessary when the springs are at right angles with the axle, as the upper part ofthe spring can be set steeper than the lower, to regulate-the backward motion ofthe axle when the front part of the spring is fastened to a solid shackle, as in the usual manner.

The rear end of the shackle, where it is fastened to the cross-spring bar, may be hinged so that its motion will be more free than when fastened Without a hinge. (The front end of it may also extend far enough back to receive an axle-clipfor fastening it to the bar G.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is i l. The half-springs A and spring-bar D, in combination with the springs B, asA and for the purposes set forth.

2. The 4spring-bars D D and cross-spring bars G Gr, in combination with the springs A A and B B, as and for the purposes herein set forth.

In testimony that I claim the foregoing as Witnesses A. J. KIDD,

WINsoN D. DUNN.
