TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 280,875,.dated'J'u1y 10, 1883.

Application filed May 5, 1883. (No model.)

nexed drawings, making part of this specification, in which- Figure 1 is a side elevation, and Fig. 2 a rear elevation, of a road-cart having the improvement; Fig. 3, a view in perspective, upon an enlarged-scale, of the toggle and the parts immediately therewith connected; and Figs. 4 and 5 diagrams showing the movement of the toggle.

The same letters denote the same parts.

The design of this invention is to provide an improved means for preventing the rocking, jolting motion of the ordinary road-cart.

In consists, in combination, of a fifth-wheel, which support the cart-body at or toward its rear end, anda joint resembling atoggle-j oint, which supports the cart-body at or near its forward end.

Aside from its improved features,the roadcart A may be of the customary form, B representing the cart-body; O, the axle; D D, the wheels; E E, the thills, and F the cross-bar of the thills.

In place of attaching the cart-body or the spring supporting the cart-body directly and rigidly to the cart-axle a fifth-wheel, G, is interposed between the axle and the body-that is, at or toward its rear end the cart-body is so connected with its support (whether that support be the axle or any-spring or part above the axle) as to enable the body to swing horizontally thereupon. The preferable mode of pivoting the body for this purpose is that shown-a fifth-wheel, G, immediately above the axle, and connecting the axle with the spring H, which in turn supports the rear end of the body. .At its forward end the cartbody is supported by means of the jointed 5 connection I. This connection is of such a nature as to enable the cart body to swing laterally upon its bearing at its rear end, but also so that when the forward end of the body tends to swing it also tends to lift. This 5c form of connection resembles, as stated, a toggle-joint having two parts, i and i, jointed together at i", to enable one part to turn vertically upon the other. The cart-body, by means of suitable irons, i i, is attached to the 55 lower part, i. The upper part, 2', is swiveled at 13* in the cross-bar. The effect of this connection is this: As the shafts .are swayed or vibrated vertically in use, the motions are prevented from being communicated to the cart- 6c body, for the motion of the shafts cannot be communicated to the cart-body without causing the lower part of the joint I to turn upon the upper part of the joint I, as indicated in Figs. 4 and 5; but this tends to lift the forward 6 5 end of the body. The weight of the body and the load carried act to resist this tendency, and the practical effect is to largely dissipate the shaft motion and prevent its being felt by the occupants of the cart. 7:

One or more of the joints I can be used at the forward end of the cart-body.

ported by the fifth'wheel and the joint I, substantially as and for the purpose described. F. J. SPRINGER. O. J. SPRINGER. Witnesses:
