SPRING-SADDLE.

Application filed March 10, 1913.

like, and has for its object to provide a structure which is more simple, eflicient and inexpensive than any that have heretofore been constructed.

The many features and advantages of the device will be fully understood from the following detailed description and included in the claims.

Referring to the drawings :Figure 1 is a rear elevation of a saddle with the invention complete thereon. Fig. 2, detail plan view of one of the resilient cantle supports shown in Fig. 1, as will be fully described hereinafter. Fig. 3, a modified form of the invention, as will be fully described hereinafter.

In Figs. 1 and 2 of the drawings, the device comprises a seat 10 mounted upon a main frame 11 composed of two trusses 12 and 13. These trusses are each connected to the cantle of the seat by resilient cantle supports but as they are both exactly alike except that the parts are reversed, only one will be described in detail as the same will apply equally to the other support. This cantle support comprises an extension spring lat suspended by its upper extremity from the rear extremity of the truss. To the lower extremity of this spring 14: is secured the lower extremity of the upright rod 15 which extends upwardly within the coils of the spring and has its upper extremity secured to the under face of the cantle of the seat. Suspended also from the rear extremity of the truss is a second extension spring 16 which lies within the coils of the first extension spring and also envelops the upright rod. At the lower extremity of the spring 16 is formed a loop or eyelet 17 which envelops the upright rod and is only of slightly greater diameter than the diameter of the rod and at an interval above this loop or eyelet is formed a fixed collar or Specification of Letters Patent.

shoulderlS of greater diameter than the diameter of the eyelet.

In operation, when the bicycle encounters an obstruction, the weight of the rider causes the extension spring 1 1 to be extended until the rod has been depressed suiiiciently to cause the shoulder 18 to contact with the loop or eyelet 17 when the spring 16 will also be extended and the resistive force of both springs will act jointly to support the load. Thus it is possible to make the extension spring 14; of

li ht wire which produces the easy riding action of such a wire spring and when a shock too great to be withstood by the first spring is encountered, the second spring comes to its assistance with as great or greater resistive power than would be produced by a single spring of large wire.

In Fig. 3 is shown a modified form of the invention in which instead of the collar or shoulder 18 of the embodiment shown in Fig. 1, a coil compression spring 19 envelops the rod 20 and when this rod is sufliciently depressed, this spring acts between the eyelet or loop 22 at the lower extremity of the extension spring 23 and the shoulder formed by the bend in the upper portion of the rod so that this extension spring is extended and the compression spring is compressed, thus producing a double bumper spring action.

The applicant is aware that a considerable number of changes in the construction and arrangement of parts can be made by any one skilled in the art without departing from the scope of his invention and he does not care to be limited to the particular embodiment herein shown and described.

What I claim as my invention and desire to secure by Letters Patent is 1. In a device of the class described, a seat, a supporting frame therefor, and resilient supports connecting said seat with said frame each comprising an extension spring interposed between said seat and said frame to support said seat under normal conditions, and a second extension spring adapted to coact with the first spring after said first spring has been partially extended to support said seat under abnormal con ditions.

2. In a device of the class described, a seat, a supporting frame therefor, and resilient supports connecting said seat with said frame each comprising an extension spring interposed between said seat and said frame to support said seat under normal conditions, and a. second extension spring enveloped by the coils of the first spring and normally inactive but adapted to coact with the first spring after said first spring has been partially extended to support said seat under abnormal conditions.

3. In a device of the class described, a seat, a supporting frame therefor, and resilient supports connecting said seat with said. frame'each comprising an extension spring suspended by its upper extremity from. said frame, an upright rod having its lower extremity secured tothe lower extremity of said spring and its upper extremity connected to said seat, adapted to support said seat under normal conditions, and a second extension spring likewise suspended from said frame adapted to coact with the first extension spring after said first spring vhas been partially extended. to support said seat under abnormal conditions.

4. In a device of the class described, a seat, a supporting frame therefor, and re- .silient supports, interposed between said seat and said frame each comprising, an extension springsuspended by its upper extremity from said frame, an upright rod connectving the lower extremity of said spring with said seat, and a second extension spring adapted to have its lower extremity engaged by a projection on said rod when this rod is sufliciently depressed and to then coact with the first spring in supporting said seat while said rod is thus depressed.

5. In a device of the class described, a seat, a supporting frame therefor, and resilient supports interposed between said seat and said frame each comprising, an extension spring suspended by its upper extremity from said frame, an upright rod connecting the lower extremity of said spring with the under side of the cantle portion of said seat, av second extension spring also suspended by its upper extremity from said frame and extending downwardly within the coils of the first spring, aneyelet upon the lower extremity of said second spring loosely enveloping said rod and free to slide thereon, and a projection on said rod normally at an interval above said eyelet but adapted to coact therewith when said rod is sufiiciently depressed to cause said second spring to be extended and to act in conjunction with the first spring to support said seat.

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