SPRING-VEHICLE.

SPECIFICATION forming part of Letters latent No. 244,957, dated July 26, 1881.

Application filed May 11, 1881. (No model.)

To all whom it may concern: 7

Be it known that we, HENRY A. WALKER and BENJAMIN G. WALKER, both citizens of the United States, residing at Kingston, in the county of Ulster and State of New York, have invented new and useful Improvements in Spring-Vehicles, of which the following is a specificationf by a hinge-joint, and is provided with a safetyhookadaptedto engage the fifth-wheel.

This invention is illustrated in the accompanying drawings, in which Figure l is an inverted plan. Fig. 2 is a longitudinal section in the plane or as, Fig. I. Fig. 3 is a transverse section inthe-plane y y, Fig. 1. 7

I Similar letters indicate corresponding parts. In the drawings, the letter A designates the platform or bottom of our wagon, and B the box or frame which supports the seat S.

Thebottom A and the seat-supporting box or frame B are connected by cross-springs O O, which are fastened to the bottom A at the middle, and to the box or frame B at their opposite ends, as shown in Figs. 1 and 3. The bottom A rests upon end springs, D D,

two at each end, the inner ends of said end springs being firmly secured to the bot-tom, while their outer ends are fastened respectively to the bolster E and to the head-block E. By this arrangement theweight of the persons occupyingtlle seat S is supported by the cross-springs G G, and through them by the end springs, D D, and bolsters E E, while the load distributed over thebottom A is supported only by the end' springs, D D, thus giving to the occupants of the seat the benefit of a double set of springs, while at the same time the springsare distributed in such a manner that the wagon is not liable to tilt over to one side, even if the load should not be quite evenly distributed.

The bolster E rests upon the hind axle, F, and from this axle extend back-stays G G to the ends of a transverse bar, H, which is firmly secured to the platform or bottom A. By the action of these back-stays the bottom is steadied in its position.

The bolster or head-block E rests upon the front axle, I, and it is connected to the platform or bottom A by the end springs, D, as previously stated. Through said head-block and the fifth-wheel J, situated between the head-block and the axle, extends the kin g-bolt J, on which the front axle turns.

- K is the king-bolt stay, which is connected to the bottom A by a hinge-joint, L, at one end, its other end being connected to the kin gbolt, and which is provided with a hook, N, passing through and within the rim of the fifth-wheel, as shown. The joint L-allows the stay K to be made rigid, while the hook N engages the fifth-wheel J in case the king-bolt breaks, thus'preserving, to an extent, the connection between the axle and the head-block.
