BICYCLE-SADDLE SPRING.

SPECIFICATION forming part of Letters Patent No. 478,430, dated July 5, 1892.

Application filed April 5, 1892. Serial No. 427,785. (No model.)

To all whom it may concern:

Be it known that I, CHARLES HENRY HOLDS- WORTH, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented. certain new and useful Improvements in Bicycle-Saddle Springs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same..

This invention relates to bicycle-saddle springs; and it has for its object to provide a spring of this character consisting of two members adjustable one with relation to the other, whereby the tension of the` spring is adapted to be regulated at will.

A further object of the invention is to pro-l vide a simple and improved spring of the class mentioned which will possess advantages in point of i inexpensiveness and durability in construction, ease of adjustment, and general efliciency. A

In the drawings, Figure l is a side elevation of a bicycle-saddle spring embodying my invention. Fig. 2 is a vertical longitudinal sectional view thereof, the adjustment being illustrated in dotted lines. Fig. 3 is a transverse sectional view on the line -x x, Fig. 2. Fig. 4 is a detail perspective View of the clip for attaching the spring to the bicycle.

Corresponding parts in 'the figures are de noted by the saine letters of reference.

Referring to the drawings, A designates the saddle support or standard, which 'is preferably of the well-known L-shape pattern, the horizontal membera of said support or standard projecting rearwardly. Upon said arm is mounted a clip B, which is provided with a horizontal cylindrical bore b for receiving said arm and with a set-screw b for rigidly binding the clip thereto. The clip is also provided with a flat socket b2, formed vertically in the clip, or at right angles to the bore b. Centrally through one wall of the socket is passed a set-screw b3.

C designates the main spring, which is formed of flat spring-steel or other spring metal. This spring has its lower vertical end c seated in the socket h2 and secured in position therein by the screw b3. From the vertical end c the spring C is curved forwardly, forming a yielding or spring bend C. The

spring is then curved upwardly and rearwardly, forming a second yielding or spring bend C2, thus providing a compound spring. The rearward extension C3 of the spring is continued some distance beyond the vertical plane of the end c, said extension having a slight upward curve.

D designates the auxiliary spring, which forms, in conjunction withv the spring C, the complete saddle-spring and is constructed of fiat spring metal, corresponding to the spring C. The spring D has its rear end d slightly curved to conform to the contour of the forward end of the extension C3 of the spring C, upon which it rests and to which it is adapted to be bound. From the end d the spring D is extended forwardly in an upward curve, as shown at D', thence slightly rearwardly, and finally its free forward end d curved forwardly. 4

The two springs C and D are secured together by a clip E, having a set-screw c passing through its upper side and adapted to be bound upon the contracting members of the springs.

The operation and advantages of my invention will be readily yunderstood by those skilled in the art to which it appertains. In practice the saddle-seat is suspended between the end d of the spring D and the extreme rear end of the member C3 of the spring C. Assuming that the springs C and D occupy the relative positions illustrated and a greater tension is desired,the screw e is loosened and the spring D then adjusted farther forward, thus decreasing the leverage on the member C3 of the spring C andrendering the latter spring more rigid; but if less tension is desiredjhe spring D is adjusted in a rearward direction, which adjustment, as will be obvious,.produces the reverse result to that just described. p

By constructing the spring C with the` two bends C and C2 it willbe apparent that this single spring has both a forward and rearward yielding movement, while at kthe same time by reason of the flat construction of both the springs C and D all side play of the saddle is overcome.

I claim as my invention- 1. Abicycle-saddle spring consisting of. a main spring having a vertical securing end,

from whence it is curved forwardly, upwardthe support or standard and provided with a 1 y, and finally rearwardly, and an auxiliary Vertical socket for receiving the securing end front spring mounted on said main spring and of the main spring, a horizontal socket for the 15 projecting forwardly and upwardly, substansupport or standard, and with set-screws 5 ially as and for the purpose set forth. adapted to engage said socket, substantially 2. As an improvement in bicycle-saddles, as and for the purpose set forth. the combination of a main spring ourlved ffor- Iutestimony whereof I aiiix my signature in wardly from its securing end, thence upwarclpresence of two witnesses.

ly, and finally rearwardly, an auxiliary front; l* CHARLES HENRY IIOLDSWOR'IH. 1o spring adjustably connected at its securing XVitnesses:
