FRANK DOUGLAS, OF CHICAGO, ILLINOIS.

BICYCLE-SADDLE.

SPECIFICATION forming part of Letters Patent No. 550,925, dated December 3, 1895.

Application filed December 31, 1894. Serial No. 533,472. (No model.)

To all whom it may concern.-

Be it known that I, FRANK DOUGLAS, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a new and useful Improvement in Bicycle- Saddles, .of which the following is a specification.

My invention relates to a bicycle-saddle provided with a convenient, strong, and adjustable fastening for the forward end of the spring of a saddle, which enters the clip that is fastened to the forward end of the saddleleather. This clip is formed to receive the spring, which slides freely into it and is provided with a bolt and wedge-shaped washer, which holds the spring-clamp firmly to the clip. Loosening the nut on the bolt makes the spring adjustable for taking up the stretch of the leather by sliding the spring back in the clip.

The saddle-spring is made of wire, doubled back in parallel lines. The wires of the front portion of the spring, extending back a short distance from the clip, are only wide enough apart to admit of a bolt between them. The remainder of the length of the wires of the spring are widened out in parallel curved lines the right distance apart to receive the clamp-seat-post fastening. The extreme rear end of the wire springs are curved out and around cantle-bolts at the rear end of the saddle-leather.

In the drawings, Figure 1 is a side elevation of the saddle, showing the leather broken away in the front to expose to view the clip and the spring-fastening attachment. Fig. 2 represents a plan view showing the under side of the saddle. Fig. 3 shows a perspective view of the upper portion of the seat-post clamp. Fig. 4 shows a front view of the lower portion of the seat-post clamp, which is provided with a set-screw passing up through its center. Fig. 5 shows a sectional end view of the front clip cut through the center of the clip and bolt at right angles to elevation, Fi 1.

In making my improved saddle I employ, preferably, a round wire (spring A) made of one piece anddoubled back upon itself at a,

to admit of the clamp-bolt B, the spring-wires extending back parallel with each other, and where it enters the clip the inwardly-curved edges of the back end of the clip are formed to fit and receive the double wires of the spring. This spring may be made of two separate wires instead of the loop, as shown in the drawings, and be held by the same clamping device. The portion of the wire spring where the wedge-shaped washer comes in contact with it is notched to. correspond with notches in the wedge-shaped washer, which prevents the wires from slipping endwise where they are clamped by the bolt. The bolt B may be provided with a large flanged end, and passes through a hole in the clip between the wires of the forward'spring, where it receives the clamp-washer O and nut D. The spring is clamped tightly between the wedge-shaped washer and the hooked edges of the clip. The back ends of the wire spring A are formed into round eyes to fit over the cantle-bolts E E at the back end of the saddle-leather. Theclip F is curved to correspond to the inside of the front end of the saddle-leather and provided with three or more rivets to hold it firmly to. the leather. The seat-post clamp is made of two parts, as shown in Figs. 3 and 4.

Fig. 3 is a perspective view showing the holes through the two upright wings g g for the seat-post, and the two lower edges are made hook-shaped to fit under and receive the two parallel wires of the spring A at the widened portion of the spring. a

The lower portion of the clamp is the screwclamp shown at Fig. 4, which passes down through the nearly square opening in the upper portion of the clamp, Fig. 3.

The curved hooked ends h h of this portion of the screw-clamp rest upon the top of each wire of the spring A, while the end of the setsorew presses against the seat-post, thereby clamping the wires of the spring A between the curved or hooked ends of clamp Fig. 3 and clamp Fig. 4.

What I regard as new, and desire to secure by Letters Patent, is

leaving just spaceenough between the wires In a bicycle saddle, a forward clip shaped at its forward end to fit a saddle leather, while the back end is formed with inwardly curved or hook shaped edges to receive and to fit around the double wire saddle spring when used in combination with elzunp bolt D passing between the wires of the spring and a wedge-shaped washer to force the wires firmly into the hook-shaped sides of the elip for the purpose herein specified.
