SPRING FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 237,456, dated February 8, 1881.

Application filed J' une 21, 1880.

To all whom it may concern:

Beit known that I, J osEPH TIL'roN, a citizen of the United States, residing at the city of New York, in the county and State of New York, have invented certain -new and useful Improvements in Springs for Wheeled Vehicles; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to secure greater ease and elasticity in the springs for wheeled vehicles than can be done by means of either the elliptic or other steel springs or the side-bar springs only, and also to avoid the sagging of the bottom, board or riding-platform,`and the consequent shortening of the space between the seat and the dash-board, as in the buckboard.

To do this l construct the bottom board of one or more pieces of wood, and made of such dimensions that it will tit into the `lower part within the sills of the body to be used, but not so tightly as to touch the body upon either side or end, leaving sufficientroom for action of the body without chan g or squeakin g. The bottom board rests upon and is riveted to two cross-bars, near and equidistant from the middle of it, made of iron, extending from and attached to the ordinary side springsor bars on each side, and parallel with the body. These cross-bars do not extend so as to touch the frame-work of the body on either side, but are curved downward, as shown in the accompanying drawings, to admit of the action of the body, andA then curved upward and attached to the side bars. The entire weight of the load is upon these cross-bars.

At each end of the body is an iron half or semicircular rod, extending from one side sill to the other; and the ends rest in a rubber cap or journal framed into the side sills, upon (Model.)

which the ends of the bottom board rest and are secured by rivets or bolts to this rod. This rod is the only connection between the body and the bottom board.

The seat being a part of the body, and not connected with the bottom board, the weight upon the seat comes upon each end of the bottom board and has the same spring as in the buckboard, but does `not decrease the distance between the seat and the dash-board, as it does when the weight comes upon the middle bottom board.

The axle-trees are curved or cranked downward, as shown in Fig. 3, thereby permitting the body to set as low as any side-bar wagon now in use. These side bars may rest upon' the axle or upon a cross-bar in front, and an iron plate attached to the hind axle.

In the drawings, Figure lis aside elevation ofthe carriage-body, showing the side spring. Fig. 2 is a sectional View, showing the springbottom and its attachments. Fig. 3 is a transverse section through the body, lookin g toward the rear.

a a are the side bars, extending from axle to axle. b b are the iron crossbars, upon which the bottom board rests, curved at o ciand attached to the side bars at d d,- ce, the curving or cranking of the axle; f j', the' india-rubber cap or socket in which the ends of the bar or half-rod rest that attaches the bottom board to the body. g g are the spring bottom board as it stands with no weight on the seat.

I claim as my improvement- The combination, substantially as set forth, of the cranked axles, the side bars, the supportingbars, having bends c, the spring-bottom, and vehicle-body.

JosEPH TILToN.
