\VILLIAM BASIL XVILBERFORCE, OF BOGNOR, ENGLAND.

SUPPORT FOR SADDLES FOR CYCLES. l

SPECIFICATION forming part of Letters Patent No. 617,000, dated January 3, 1899. Application filed December 28,1897. Serial No. 664,115. (No model.)

To all whont it may concern:

Be it known that I, \VILLIAM BASIL \VIL- BERFORCE, a subject of the Queen of Great Britain, residing at Bognor, in the county of Sussex, England, have invented a new and useful Improvement in Supports for the Saddles of Cycles, (for which I have obtained a patent in Great Britain, No. 13,246, bearing date May 28, 1897,) of which the following is a full and complete specification.

This invention relates to devices for sup porting bicycle-saddles; and it consists in the novel construction and combination of the parts,hereinafter fully described and claimed.

The drawing shows a sectional side View of the support.

A is a member, preferably tubular, which fits into the usual socket of the bicycle-frame in which the seat-pillar is placed.

B is a member, also tubular, which is pivoted to the upper part of the member A by a pin a and socket a, or in any other approved manner, and which extends forwardly of the pivot-pin a. A roller 1) is journaled in the front end portion of the member B, and b is a cap which closes the rear end of the member B. The saddle F is supported from the member B in any approved manner in front of its pivot-pin. A stop b is provided for preventing the member B from descending too far in front.

0 is a spring arranged within the member B. The front end of the spring 0 is connected with the upper part of the member A by a flexible connection D, such as a band or chain, which passes over the roller b.

E is a screwed bolt which passes through a hole in the cap Z) and is connected to the rear end of the spring 0. E is an adj Listing-nut which engages with the bolt E and bears against the said cap. The tension of the spring is adjusted by turning the adjusting-nut.

This support enables the saddle to adjust its inclination automatically to the position of the rider on various gradients and enables him to exert his strength to greater advantage in propelling the bicycle. The inclination of the saddle increases as the rider increases the pressure on the pedals at the beginning of a hill, and therefore affords him a better purchase or support.

WVhat I claim is 1. In a saddle-support, the combination, with a member A carried by the frame, of a tubular member B pivoted to the member A and extending forwardly thereof, a spring arranged in the member B, a guide at the front end of the member B, a flexible connection passing over the said guide and secured to the member A and the spring respectively, and a screw for varying the strength of the said spring, said screw being operatively connected with the said spring and with the rear end portion of the member B, substantially as set forth.

2. A support for the saddles of velocipedes, consisting of a member A adapted to be fixed to the frame of the machine, a tubular member B pivoted to the top of the member A and extending forwardly, a spring 0 located in the tubular member B, a band or chain connecting the front end of the spring 0 with the member A near its upper end, the said band or chain passing around a roller 6 carried by the forward end of the member B, a screwbolt E connected to the rear end of the spring 0 and passing through a cap 1) closing the rear end of the tubular member B, and an adjusting-nut E mounted on the screw-bolt E as set forth.
