' BICYCLE SEAT.

(No Model.)

BICYCLE-SEAT.

SPECIFICATION forming part of Letters Patent No. 274,163, dated March 20, 1883. I Application filed September 21, 1882. (No model.) t

Seats, of which the following is a description sufficiently full,clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompany-' ing drawing. forming a part of this specification, in which the figure is a sectional side elevation.

In ordinary bicycles the saddle of the seat is usually mounted on atlat spring which is rigidly attached. to the backbone of the machine. This spring, while taking up or neutralizing the vertical movements of the seat produced by passingovera rough road or track, does not take up or neutralize to any great we tent the horizontal'inoveinents produced by the same cause.

Myinvention is designed to obviate this objection and to that end I construct and arrange the parts which constitute the seat in anovel and unique manner, as hereinafter fully set forth and claimed, by which a more desirable and efi'ective device of this character is produced than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant'withsuch matters from the following explanation, its extreme simplicity rendering an elaborate description unnecessary.

In the drawing, A represents the main wheel, B the handles, 0 the saddle, and Dthe backbone, of the bicycle. A semi elliptic spring, m, is rigidly secured to the backbone by the nuts and bolts d, each end of this spring carrying two pendulous links, a. a, which 7 are jointed theretoin such a manner as to swingt'reelyin line with the springs. Aspring, E, is arranged horizontally'above the spring m, and has its ends as 00 curved down ardly and inwardly under the ends of the springm, where they are jointed to the lower ends of the links ca, as shown, the saddle O being firmly secured to the upper side of the spring E by the nut and bolt 1 or in any other convenient manner.

In the use or my improvement it will be obvious that the jar or vertical movements of the backbone I), produced by the wheel A in passing'over a rough road or track, will be taken up or neutralized by the conjoint action of the springs E m, and also that the ill or disagreeable effects of all horizontal movements of the seat produced by the wheel coming in contact with obstructions in its path will be overcome by means of the jointed pendulous links a a, and the peculiar manner of forming and connecting the springs E m, whereby the spring E is enabled to move or swing slightly back and forth on the line of traverse followed by the machine.

Having thus explained my improvement, what I claim is-- l The combination of the bicycle-backbone D,

the upwardly-curved semi-elliptic spring tn,

the saddle U, attached to said longitudinal springs,substantially as described.
