VEHICLE-SPRING.

SPECIFICATION forming part of Letters PatentNo. 293,801, dated February 19, 18 84.

Application filed May 29, 1883. (No model.)

and more particularly pointed out in the claim.v

In the drawings, Figure 1 is an inverted plan of an apparatus embodying my invention. Fig. 2 is a side elevation. Fig. 3 is a perspective View of some of the parts.

My invention relates to torsion-springs for vehicles, and has for its object an improved construction of springs of this character which shall give increased elasticity, and thus afford an easy-riding vehicle. I accomplish this object by securing to the body of the vehicle torsion springs connected at their extremities with suitable side springs, said side springs secured at their opposite extremities to an equalizer, the construction being such as to afford an unobstructed motion to the body as the springs are operated. I v

To this end, as illustrated in the drawings, A represents the body of the vehicle.

B represents the side bars.

0 represents the front head-block.

D representsthe rear axle.

E and E represent the equalizers, secured at their extremities in any proper manner to the side bars. 1

F and F representtorsionsprings, constructed of bars of suitable metal, each of said bars extending across the vehicle-body, and preferably projecting beyond the body at each side, said bars or springs secured to the body at a suitable distance in front and at the rear of the middle of the body. Each of said bars or springs is secured to the center sill, a, of the vehicle-body by a suitable bearing, f, secured thereto, the bearing being so constructed as to holdthe bar stationary at this point, which may be accomplished by constructing the bearing with a squared orifice to receive the squared bar, as shown, or in any other suitable manner. The torsion-spring is also secured to the side sills of the body a by proper bearings, f, the

construction being such that the torsi on-spring may have a free motion in said bearings, whichmay be accomplished, for instance, by rounding the bar at these points and constructing the bearings to correspond therewith, as shown.

G and G represent front and rear side springs, constructed in any suitable manner, and firmly connected at their inner extremities with the front and rear torsion-springs, respectively, in such a manner that a strain upon the side springs will be communicated to the torsion springs. As shown, the side springs are provided with bearings g and 9, connected thereto, the bars or torsion-springs being squared at their extremities, the bearings beingconstructed in a corresponding man ner, so as to hold the torsion-springs from turning in the bearings. At the opposite extremities the side springs are connected at the front and rear'of the vehicle to the front and rear equalizers, E and E, in any suitable manner. I prefer to locate these side springs outside of the body and inside the side bars.

The operation of the device will be readily understood V V A vehicle provided with springs constructed as herein described presents a neat appearance. The springs are found to be veryelastic, while, also, there is less sidemotion than is the case with side-spring ehicles as com-' monly constructed.

Instead of securing the front and rear ex-- tremities of the side springs to the equalizers E and E, they may be, if preferred, secured "directly in any proper manner to the runninggear of the vehicle.

What Iclaim is- In a side-bar vehicle provided with front and rear equalizers, the-combination, with the vehicle-body, of front and rear torsion-springs rigidly secured to the body intermediate of EDWARD S. SMITH.
