SPECIFICATION forming part of Letters Patent No. 242,731, dated June 7, 1881.

Application led March 1B, 1881.

To all whom it 'may concern:

Beit known that I, LYMAN O. WOOD, a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Vehicle-Springs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable thersskilled in the art to which it appertains to make and use the` same, reference being had to the accompanying drawings, and to letters or gures of reference marked thereon, which forma part of this specification, and in which- Figure l is aside elevatioinpartly in section, with the wheels removed, of a vehicle y with my improved spring applied thereto; and

Fig. 2 is a detailed view ofthe spring.

This invention has relation to improvements in vehicle-springs, its object being to permit of the equalizin g of pressure upon the springs and the distribution of the bearing-points ot' the springs upon thevehicle-body; and it consists of compound springs the convexities of which are supported in or connected by clips to the vehicle-body, while their inner ends are connected to and adapted to have motion upon spindles or bolts depending from the vehi cle-body, and encircled below the` body with springs, substantially as hereinafter more fully set forth and claimed.

Referring to the accompanying drawings, A A indicate the individual springs of the compound springs, one being arranged upon each side of the vehicle. Each spring A is semi-elliptical in form, with its convexity supported in a clip, c, suitablybolted thereto, and, in turn, connected to the vehicle-body by aplate, b, bolted to the clip and to the under side of the body, as seen in Fig. l. The springs A, arranged in pairs upon each side of the vehicle, the rear springs being connected, as shown, or in other suitable manner, to the rear or hind axle, while, in addition to their attachment directly to the vehicle-body, they `l, in a bridge or arch, c.

(No model.)

are also connected indirectly to the vehiclen bodyattheirinnerends.' The forwardsprings, likewise directly connected to the vehicle-body, as before described, are connected in similar manner as the rearsprin gs to the bolster of the front axle, while their inner ends are also indirectly connected to the body.

The means of attachment for the inner ends of each pair of springs consists of a plate, c, linked, as at d, to the said ends of the springs, and fitted to slide vertically upon a bolt or spindle, B, extending up through the Vehiclebody, and seated, preferably, as shown in Fig. Ooilcd around the spindle or bolt B, below the body, is a spring, B', not necessarily, however, a coiled spring,

- which acts downwardly upon the plate .c to sccure it yieldingly in position upon thebolt.

From the foregoing it will be noticed that asweight is put upon the springs they will be permitted to bear, not only at their convexity, upon the body, but also upon the center of the body, and thus distribute their points of bean in gand equalize the pressure upon the springs.

It is also readily seen that greater resiliency is obtained, which promotes comfort and ease.

Having thus fully described my invention, I claim and desire to secure by Letters Pat entl. rIhe combination of the semi-elliptical springs A, arranged to connect with the hind axle and forward-axle bolster, and vertical sliding plate O, and bolt or spindle B, and spring B'.

2. The combination of the arch-spring c, springs A A, clips b b, plate c, and spindle B, substantially as shown, and for the [purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

LYMAN O. WOOD.
