SPRING-VEHICLE.

SPECIFICATION forming part of Reissued Letters Patent No. 11,490, dated April 23, 1 895. Original No. 438,543, dated October 14, 1890. Application for reissue filed October 30, 1891. Serial No. 410,694-

-To all whmn it may concern.-

of parts hereinafter described, and pointed.

out in the claims. I

In the accompanying drawings,'Figure 1 is a side elevation. Fig. 2 is a front end elevation. Figs. 3 and 4: are views in perspective of the equalizing or balancing-spring detached. Fig. 5 is a plan of rear equalizing-spring.

A, represents the body of the vehicle, to which at the longitudinal and lateral center thereof is attached the principal spring B of the variety shown. The extremes of this spring extend under either axle, the spring being secured to the rear axle in the usual manner by means of a clip. The forward end of spring B is pivotally secured to the forward axle by means of a king-bolt C, the latter also extending through the cross-bar above, such construction serving for or in place of the ordinary fifth-wheel. These parts are further secured by a clip, 0, the latter embracing -the cross-bar, and the bolt-ends of the clip being separated far enough to allow the forward axle to swing the limited distancenecessary.

D and E, are the equalizing or balancingsprings. One or both of these springs are constructed each of a single flat bar or leaf of spring-steel folded diagonally, as shown at e and cl, to form approximately a U-shaped spring. A balancingspring thus folded cannot only be cheaply made, but possesses great strength and durability. The central member D of spring D is provided with holes d for securing this member to the under side of the body-cross-wise thereof, the free ends of the spring extending under the rear axle,

to which they are secured byclips. The central member E of spring E may serve as a cross-bar in which case the central portion of this member should be blocked, as shown in Fig. 3, the ends of the spring being secured to the under side of body A near the sides of the latter. Hole 6' is for the king-bolt. In case it is preferred to use a wooden cross-bar in front, the forward equalizing-spring might be a facsimile of the rear spring D, the mannor of attaching such spring to cross-barF being shown in Fig. 4. The chief function of the equalizing or balancing-spring is to prevent the vehicle body from rocking sidewise and in a measure to prevent the body from rocking endwise and to hold the body steady Without affecting the easy riding qualities of the vehicle. These springs also help to sustain the load, and to this extent relieve the strain on spring B, and more especially they relievespring B from torsional strain.

What I claim is 1. In a spring vehicle, the combination, with vehicle-body and longitudinally centrally-located spring, of equalizing or balanclngspringssecured to the opposite ends'of the body and to the axles, one of said springs constructed of a fiat bar or leaf of metal, bent substantially as shown, the central member being fastened crosswise to the under side ofv the vehicle body and the endsv to the axle, and the other spring formed, substantially as shown, with its ends secured to the vehicle body, and the central member constituting a cross-bar having a hole adapted to receive the king-bolt, substantially as set forth.

2. The combination, with the body of a vehicle and longitudinal centrally-located spring, of balancing or equalizing-springs secured to the body and to theaxles 0r cross-bar, said springs composed of a flat bar or leaf of metal bent into three members, the central member of which is in a different plane from the other two members and formed by bending the end members across the central member, substantially as set forth.

3. In a spring vehicle, the combination with a vehicle body and a longitudinal a balancing or equalizing spring secured to the body and to the axle or cross bar, the said balancing or equalizing spring being comti0n,ir1 the presence oftwo witnesses, this12th posed of a bar or leaf of metal bent into three day of October, A.
