SIDE SPRING.

SPECIFICATION forming part of Letters Patent No. 283,052, datedAugust 14, 1883.

Application flied November 24, 1882. (No model.)

To all whom it may concern Be it known that I, CHARLES R. WILSON, of Detroit, county of Wayne, State of Michigan, have invented anew and useful Improvement in Springs for Side-Bar Vehicles; and I declare the following to be a full, clear, and exact description of thesame, such as will e11- able others skilled in the art to which it pertains to make and. use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention consists in the combinations of devices and appliances hereinafter specified;- and more particularly pointed out in the claim; V

Inthe drawings, Figure 1 is a plan view, Fig. 2 a side elevation, and Fig. 3 aperspective View, illustrating my invention.

It is the object of my invention to produce and combine with a side-barvehicle a spring which shall be composed of the two following elements: Alower section extending across the sessed by the ordinary double spring, in which the upper and lower sections areparallel with each other, and the further advantage of a greater length of spring in the upper section, between the middle and extremity of the spring, and without projecting the end of the upper section beyond the sides of the buggybody. y z

In carrying outmy invei'ition A represents the side bars of an ordinary side-bar buggy;

B, the buggy-body; G, the upper, and O the lower, section of my improved spring. 0

represents the end portions of the upper secti on, which are turned, either forward or backward, beneath thebuggy-body in a direction parallel to its length. I prefer to slope these longitudinal portions 0 so that their extremithe buggy-body through a corresponding length, andthus render the spring stifl'er.

If the spring is at the outset designed for heavy loads, the portions (3 maybe made quite short, and might be so much shortened that the,

upper section would possess only the elasticity due toits diverging portion and the torsional elasticity of the. material at the base of the longitudinal part 0.

I do not limit myself to any particular method of uniting the two sections 0 and 0. They ties only shall come up beneath the buggybody, and to secure these extremities firmly.

may be made with the lower section bent upward and the upper section bent downward .along the middle, and fastened by a bolt or suitable clips at the middle point; or both sections may be bowed upward at themiddle point, or both bowed downward at the middle point, and secured in any suitable manner,

so as to lap'upon and re-enforce each other as i the load is increased, or the sections may be separated along the middle part by one or more blocks, thus preventing them from so lapping upon each other; and I would have it understood that in constructing my spring any of the foregoing constructions are contemplated. So, also, Ido not limit myself strictly to aconstruction in which the upper section, 0, is brought out to the sides over and parallel to the lower section, for it may be started outinthat direction and then brought around, by an easy curve of greater or less radius until the extremities point to the front or rear, while the middle rests upon the lower leaf.

I am aware that it is not new to construct a spring for a vehicle-body of two flexion members or springs arranged one above the other and connected at their centers, the outer ends of the upper member being arranged parallel IOC with the ends of thelower member and secured center of said upper spring, and sidebars or to the body of the vehicle, and the ends of the other support, as and for the purpose set forth. 10 lower member being attached to the side bars In testimony whereof I sign this specificaor other support. tion in the presence of two Witnesses.

5 What I claim is- CHARLES R. WILSON.

The combination of the upper transverse Witnesses: spring, having longitudinaHy-turned end por- N. S. WRIGHT, tions, with the bottom spring, secured to the WILLIAM F. FORD.
