SADDLE FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 469,628, dated February 23, 1892.

Application filed August 31,1891.

To all whom it may concern.-

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

My invention relates to a class of saddles known as suspension-saddle. In the forward end of a leather seat is riveted a metallic front clip or hook for the purpose of attaching the front double-coil spring. This forward clip is also provided with two holes across its back end for the purpose of receivin g two stretcher or suspension springs, which extend from the cantle-bolts in the rear end of the saddle to the front clip. These stretchersprings I prefer to make with a coil or single turn near the rear end of the saddle to make it more elastic, andis also provided with nuts at its end to rest against the front clip, which are screwed up for increasing the tension of the leather saddle-seat. The back end of the saddle is provided with a sheet-metal cantle, through which two bolts and nuts pass through the loop ends of the double-coiled spring for bolting it firmly to the saddlecantle. The lower ends of the forward and rear double-coiled saddle-springs pass in over the bridge ends of the saddle-bed plate and lock under the plate into grooves across the plate between its center bolt-opening and its ends. The seat-post stud has a large projecting flange that rests against and looks over the ends of the springs, and. also has a screw-stem attached to it, which passes up through the bed-plate and is provided with a curved washer "and nut for screwing the seatpost stud firmly against the bed-plate. The long projecting flange of the seat-post stud serves the double purpose of holding the ends of the springs firmly against the under side of the bed-plate, and also serves for the tilting of the forward end of the saddle up or down to suit the rider by loosening the nut of the seat-post thread-stem,whic'h allows it to move forward or back in the oblong opening or slot of the bed-plate.

In the accompanying drawings in two sheets, Figure l is a side view of the complete saddle. Fig. 2 is a view of the under side of the Serial No. 404,235- (No model.)

complete saddle. Fig. 3 is an enlarged sectional View of the bed-plate and seat-post stud cut through the center. Fig. 4 shows the whole of the under side of the bed-plate with the ends of the coiled springs resting in position and the bridges across the ends of the bedplate over the forward and rear springs. Fig. 5 shows the under side of the metallic clip, which is attached to the forward end of the saddle-leather.

A is the forward metallic saddle-clip, which is riveted into the forward part of the leather seat. In the projecting hook a of clip a forward double saddle-spring B is hooked on or connected. At the rear end of the saddleclip A are two holes 0 o. In the rear end of the saddle is a metallic sheet-meta1 cantle D, riveted into the leather of the saddle, through which are two bolt-holes to receive bolts E E for holding the rear double-coiled spring F of the saddle and also for holding the two suspension-springs G G at their rear end. The forward ends of the suspension-springs G G pass through the holes 0 c in forward clip A. The forward ends of the suspension-springs G G are threaded a short distance, upon which nuts 9 g are screwed to rest against the rear end of clip A, where they enter the holes 0 c. The bed-plate H serves as a holder for the lower end of the forward spring B and rear springs F, and is provided with connectingbridges I I across its extreme ends, over which bridges the saddle-springs pivot and rest, while the extreme lower ends of the springs look into grooved recess J J across the under side of the bed-plate H. An opening K through the bed-plate in its center is made to receive the threaded end L of the seat-post stud m. A Washer "it between the nut O and the curved surface of the bed-plate H has a flat top surface, upon which is screwed the nut O for the purpose of clamping the lower end of the saddle-springs firmly against the under side of the bed-plate H. By this combination of seat-post stud and bed-plate the lower end of the springs of the saddle are held firmly in place, and at the same time adj ustment for the lowering and raising of the front of the saddle is eifected by the loosening of the single nut O on the stem L of the seatpost stud m. WVhen the rider wishes the leather of his saddle more tightly stretched or suspended, he turns up the small nuts g g on the ends of the suspension-springs G G without any change whatever in the springs 5 B and F. By this method of suspending the leather of a saddle I am able to use lighter and more springy wire in the large springs B and F, and thereby making a more easy and flexible seat than can be obtained by the ordi- 1o nary suspension-saddle.

Having thus described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is-

The seat-post stud, in combination with the bed plate H, springs F, forward spring B, clip I 5 A, and suspension-springs G G, substantially as described.

FRANK DOUGLAS.
