CLEMENT FORD, OF AXMINSTER, ENGLAND.

CYCLE-BRAKE.

SPECEFICATION forming part of Letters Patent No. 684,053, dated October 8, 1901.

Application filed May 21, 1901. Serial No. 61,218. (No model.)v

,To a/ZZ whom, it may concern.-

Beit known that l, CLEMENT FORD, gentleman, a subject of His Majesty the King of Great Britain and Ireland, residing at Lower House, Branscoinbe,AXminstei-,in the county of Devon,England,have invented certain new and useful Improvements in or Relating to Cycle-Brakes; and I do hereby declare the following to be a full, clear, and.Y exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to those cycle-brakes 'which are adapted to be operated by a backward movement or pressure of the riders body, and has for its object to provide a brake of this type of simple, neat, and practical constructiomwhich can be supplied as a self-contained fitting, possessing all the necessary adjustments,and adapted for ready attachment to any cycle of ordinary construction.

My invention consists in the combination and arrangement of parts hereinafter described.

According to my invention the brake-actuating lever, which is provided at its free end with a back-rest or cross-piece, is fulcrumed at one end of an arm or rod dependent from and having vertical adjustment relatively to a support adapted to be 'detachably secured to the saddle-pin and horizontally adjustable 'relatively thereto. By the vertical and horizontal adjustments provided the position of the back-rest can be easily regulated to suit different makes of saddles, which often vary considerably in height above the saddle-pin, and also to accommodate shifting of the saddie along its pin. The preferred arrangement of the support is to adapt the same to enter the horizontal tube or portion of the saddle-pin and to be slidable longitudinally thereof, means being provided for locking it in the desired position.

The accompanying drawing shows, in broken side elevation, my invention applied to a brake which acts on the driving-wheel rim of a cycle.

The operating-lever d carries at its free end a back-rest or cross-piece b, arranged just above the level of the saddle c at the rear thereof. Thislever is fulcrumed at d in the slotted end of an arm or rod e, which screws through and is dependent from the end of a support f, by which the brake is attached to the saddle-pin g. c' is a look-nut whereby the arm e after having been adjusted vertically by screwing in the supportf is fixed in position. I do not wish, however, to limit myself to the means shown for making the adjustment. The support f, as here shown, comprises a screw threaded rod passed through the horizon-tal tube of the saddle-pin g and adjustable longitudinally thereof and fixed therein by means of the nuts f', which bear against flanged plugs or collarsfz, slidable uponf and adapted to iit the bore of the saddle-pin and close the ends thereof. The said screw-threaded rod would preferably be of greater length than shown in the drawing, so as to give more range of adjustment, as also for the same object the screw-threaded portion of the arm or rod e.

From the tail of the lever d depends the rod or connection 71., attached at its lower end. to the brake-jaw Z. on is one of a pair of springs for retracting the brake.

To permit of adjusting to a nioety the Vdistance separating the brake-block h from the wheel-rim n, the upper end of the rod h is, headed and freely revoluble inthe lever a and its lower end screws through the brakejaw Z. On loosening the nut h adjustment is effected by rotating the rod h.

What I claim, and desire to secure by Letters Patent of the United States, is

l. In a cycle-brake, the combination of a support detachably connected with the saddle-pin and adjustable horizontally relatively thereto, an arm dependent from and vertically adjustable in said support, a lever actuated byabackward movement of the riders, body f ulcrumed at the lower end of said arm, and an adjustable connection between the 1ever and the brake, substantially as described.

2. In a cycle-brake, the combination of a support slidable within the horizontal portion of the saddle-pin,means for locking the support therein, an arm dependent from the rear end of said support and having vertical adj ustrnent relatively thereto,alever fulcrumed at the lower end of said arm and having a IOO buck-rest at its free end7 and a connect-ion l support, a lever afulerumed in the lower end between the lever and tho brake, snbsmnl of the erm end provided with :t beek-rest,

tially as described. and a, connection h between the lever and e I5 3. In a eyelefbrake, the combination of a brake Z, said connection being provided with 5 supportfcomprising a screw-threaded rod la screw adjustment, substantially as deadapted to be passed through the horizontal scribed and illustrated.
