STEPHEN E. HARRISON, OF NEW HAVEN, CONNECTICUT.
IMPROVEMENT IN CAR-BRAKES.
Specification forming part of Letters Patent No. l27,233, dated May 28, 1872.
Specification describing anew and Improved Oar-Brake,invented by STEPHEN E. HARRI- sON, of New Haven, in the county of New Haven and State of Connecticut.
Figure 1 represents a vertical longitudinal section of a railroad car provided with my im- Fig. 2 is a bottom view of the same. Fig. 3 is a vertical transverse section of the same on the line a c, Fig. 2; and Fig. 4 is a detail transverse section of the clevis attachment to the toggle-lever.

This invention relates to a new mechanism for applying the brakes to the wheels of steam or horse cars; and consists principally in connecting the brakebeams by toggle-levers, and in applying springs to said levers for holding them expanded, all as hereinafter more fully described.
A in the drawing represents the car-body. B are the wheels, mounted on axles C C in the ordinary manner. D D are the brake-beams, carrying at their ends the brake-shoes E E. Fis a toggle-lever, which, at its ends, is connected with the brakebeams D D, its joint a in the middle having a clevis, b, to which the ends of chains G G are secured. These chains extend to the ends of the car, respectively,
where they are fastened to shafts d d, as shown.
Pinions e e on the shafts d mesh into sliding racks f that can be forced down by the driver or attendant to so turn the shafts as to wind the chains upon them. A spring, 9, serves to keep the toggle-levers distended, and thereby to hold the brake-shoes away from the wheels.
Whenever one of the chains is wound around The chains G can be made extensible or contractible by right-and-left nuts h applied within them to jointed rods.
The ends of the toggle-levers, where they pass through the beams D, are provided with screw-threads and held by nuts it, so that by shifting said nuts the distance between the brake-beams can be more or less varied, as may be found necessary.
Suitable catches for holding the racks f down and the brakes applied may be provided.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The toggle-lever F, held in line by a straight spring, 9, connected at each end to reverselyacting brake-beams D D, and attached at the middle to chains G. G, which, respectively, extend to each end of car, as and for the purpose set forth.
