IMPROVEMENT IN CAR-BRAKE-OPERATING MECHANISMS.

Specification forming part of Letters Patent No. 184, l '79, dated November 7, 1876; application filed September 9, 1876. Y

To all whom it may concern:

Be it known that I, JACOB J. SHAFNIT, of Musc atine, in the county of Muscatine and State of Iowa, have invented certain new and useful lmprovements in Gar-Brake-Operating Mechanism; and I do hereby declare that the This invention relates to improvements in car-brake-operating mechanism, and the in vention consists in the use of a pulley, mounted on top of the car, and provided at one end with a ratchet-wheel and a retainingpawl, and also with a weighted'lever, and connected by a chain or cord with the ordinary brake-levers beneath the cars, so that it may be used to set and release the brakes, as hereinafter more fully'described, and set forth in the claims.

In the accompanying drawings, Figure 1 is .a top view of my invention, and a portion of a railway box-car; and Fig. 2 is a side elevation.

Referring to the parts by letters, A repre sents a portion of the top and one end of a box-car. B is a plate, which may be attached to the top of the car A, and carries the main working devices. 0 is a pulley wheel, its shaft 0 mounted in suitable axial hearings in standards D, which spring from the plate B. E is a ratchet-wheel on the outer end of the shaft 0; and F is a lever or handle attached at one end to the shaft 0, and has a weight, f, on its other end. G is a pawl, engaging with the ratchet E, and pivoted at g to a standard, g, projecting from the plate B. The lower end of the pawl G is extended to form a curved part, G, near the top-of the car, and convenient for the foot of the operator. H is a chain or cord, attached at one end to the pulley G, and passes over a pulley, I, seated at the upper corner of the car, and another, J, seated at its lower corner, and thence to its attachment with the brake-lever, in the ordinary manner.

For applying the car-brakes, all that is necessary is to throw the lever F back to the position shown by full lines in the drawings,

' ver F in the last-named position, and will aid in holding it in the first named, and thus relieve the pawl G of considerable strain.

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

1. The pulley-wheel O, ratchet E, weighted lever F, and pawl Gr, having treadle G, ar-

' ranged to operate substantially as and for the purpose specified.

2. The combination of the pulley (l, ratchet E, weighted lever F, and pawl G, with chain H, and pulleys I and J, substantially as and for the purposes specified.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

J AGOB J. SHAFNIT.
