UNITED STATES PATENT OFFIC EDwIN A. CI-IUBB, OFCORTLAND, NEW YORK.

SIDE SPRING FOR CARRIAGES.

SPECIFICATION forming part of Letters Patent No. 396,071, dated January 15, 1889.

Application filed November 17, 1888. Serial No. 291,080. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN A. CHUBB, residing at Cortland, in the county of Cortland and State of New York, have invented certain new and useful Improvements in Side- Bar Springs for Carriages, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to springs for buggies and carriages, usually known as sidebar springs.

The invention consists in the construction and combination of parts hereinafter set forth.

Figure 1 is a side elevation of the side bars and springs of a buggy, with box mounted on the sprii'lgs. Fig. 2 is a perspective view of the bolsters and side bars, with springs and cross-bars attached. Fig. 3 is a bottom plan of one of the springs and its support and bar.

The bolsters A A support the side bars, B B, in usual manner. The bars B have each a hanger, C, which hangers are attached near their ends to the under side of the bar by clips D D or by bolts or in other convenient manner. The hangers G are curved downwardly and inwardly, so that the central parts of these hangers are inside the side bars and below the level thereof.

The springs E E are nearly semi-elliptical in form, and are centrallysupported on the hangers C, to which they are attached bybolts or rivets F F. The hangers thus form a sort' of cradle, in which the. central portions of the springs rest, with the concave side upward. The springs E may be composed of as many leaves as desirable and extend lengthwise of the vehicle. The ends of the springs are connected by cross-bars G G, which are swiveled in loops H H in the ends of the springs, so as to be free to rock in said loops. The box K is attached to these cross-bars.

A drop-bracket, L, attached to the side bar and connected by a bolt or otherwise to the top of the spring, serves to give strength and rigidity tothe spring-connection.

The cradle formed by the curved hangers serves as a support for the central portion only of the springs when there is but little weight on them; but as the springs are straightened down by a weight in the carriage the cradle forms a support for a greater length of spring and acts as a re-enforce thereto. As the curves of the spring and cradle approximate to each other, the straightening of the spring brings it easily upon its hanger without shock.

hat I claim is- 1. The combination, with the side bars of a buggy, of curved hangers forming central supports for the springs, the curved springs centrally supported therein, and the end bars swiveled in said springs, substantially as described.

2. The combination, with the side bars of a buggy, of a pair of curved hangers, the 1on gitudinally-extending springs, and the retaining drop-bracket attached to the side bars and springs, substantially as described.

3. The combination, with the side bars, of the curved hangers secured thereto and the springs centrally supported thereon and extending lengthwise of the vehicle, all arranged substantially as shown and described.

In testimony whereof I at'fix my signature in presence of two witnesses.
