SPRING FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 340,560, dated April 27, 1886.

Serial No. 171,697. (No model.)

To all whom it may concern.-

Be it known that I, DEY COOK, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented a new and useful Improvement in Springs for Vehicles, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvementin springs for vehicles; and it consists in the peculiar construction and arrangement of devices, that will be more fully set forth here inafter and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a bottom View of a side-bar vehicle with my improved spring attached thereto. Fig. 2 is a vertical transverse sectional view of the same, taken on the line :20 00 of Fig. 1. Fig. 3 is a detail perspective view of one of my springs, and Fig. 4 shows another manner of attaching the springs.

A represents the side bars of the vehicle; B, the bolster connecting the front ends thereof; G, the rear axle, and D the body, which is suspended between the side bars by the springs F. These springs are each composed of the long arm f, the short arm f, and the connecting wrist portionf between the long and the short arms. The long arm of the spring is bent into a compound curve, and the outer end of thearm curved upwardly and adapted to be attached to a clip, G, which is secured to the side bar. The short arm f of the spring is substantially straight, drawn out straight with a gradual taper and -is curved at its outer end and adapted for attachment to the spring bar or body of the vehicle by the bolt H. The wrist ofeach of the springs is journaled in a box, I, secured to the body of the vehicle. The long arms of the springs may be formed either in a single piece drawn out fiat with a gradual taper or reenforced by one or more leaves fastened together with clip or bolt in center of leaves, as shown.

These springs are applied to opposite ends of the body of the vehicle in pairs, having their free ends extending in opposite direc tions, the long arms of each of the pairs of springs being between the arms of the springs adjacent thereto, as shown in Fig. 1.

In order to prevent rattling, rubber pack- I ings may be placed in the blocks I around the wrists of the springs.

When the vehicle is in motion, the movements and the weight of the body will be sustained mainly by the long arms of the springs, which are sufliciently elastic to cause the body of the vehicle to ride easily and without jerking motion. The wrists of the springs, being secured in the blocks I, are subjected to a partially torsion strain, which is prevented from becoming so great as to en danger the safety of the springs by the short arms thereof, which are caused to yield to the strain exerted on the wrists, and thereby receive and neutralize the torsion strain.

A vehicle-spring thus constructed is cheap and simple, causes the body of the vehicle to ride easily, and is not likely to break or wear out by ordinary use.

In Fig. 4 I have shown my spring attached to a vehicle having end bars or bolsters, 6, instead ofside bars. In this case the springs are arranged side by side in pairs at each end of the body of the vehicle, the wrists of the springs being received in the boxes I, and the short arms thereof being secured to the bottom of the body, as in the previous instance, while the long arms of the springs extend in front and rear of the body, and are received at the outer ends by clips attached to the end bars.

Having thus described my invention, I claim- 1. The spring having the long curved arm f, the shorter parallel straight arm, f,having the upturned curve at its outer end, and the torsion wrist portion f connecting the long and short arms, to convey a portion of the strain from the longarm to the short arm, substantially as described.

2. In a side-bar vehicle, the springs F,having the long curved arms f, attached to the side bars at their outer ends, the shorter parallel straight arms, f, having the upturned curves at their outer ends,which are attached to the body of the vehicle, and the connecting torsion wrist portions f", jonrnaled in boxes IOC on the bottom of the vehicle, substantially as DEY COOK.
