CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 253,249, dated February '7, I1882.

(No model.)

To all whom it may concern:

Be it known that we, ROBERT J. WILSON, of Pittsburg, in the county of Allegheny and State of Pennsylvania, and AUGUST SNYDER, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvementin Car-Brakes; and we do hereby declare that the following is a full and exact description thereof, reference' 1o being-had to the accompanying drawings, and to the letters of reference marked thereon.

Our invention relates to an improvement in `novel means for manipulating the braking mechanism of railway-cars through the me- 'dium of a shaft, or a series of shafts, forming a continuous line corresponding to the number of cars and length of train by coupling said shaft or shafts between the cars and to the tender or locomotive by means of flexible con- 2o nections and revolving the shaft or shafting by means of a suitable motor, as will hereinafter more fully appear.

To enable others skilled in the art with which our invention is most nearly connected to make and use it, we will proceed to describe its construction and operation.

In the accompanying drawings, which form part of our specification, Figure lis a side elevation of a freight-car tender yand locomotive 3o provided with our improvement.' Fig.2 is an inverted view of a car and tenderifor a locomotive, representing our improvement and its connectionsand relation to the brake-levers for, the wheels of the car or cars. Figs. 3, 4, 5, 6,

7, and S are detail views, which will hereinafter be fully explained.

1n the accompanying drawings, Arepresents a freight-car of the ordinary construction. I

C represents the tender for the locomotive D. To the under side of the car-body, or to its running-gear, is pivoted in'hearin gs a a shaft, E, furnished with a drum, F, to which, at b, is attached a chain or wire rope, G, which passes over a pulley, H, and is connected to the brakelever, I, which maybe of ordinary construction and operation; but other forms of brakes may be used, if s0 desired, such as is shown in Fig. 6, the construction and operation oi' which are well understood in railway-en gineerin g and railway-car construction, and therefore' need 5o not he further described in this specification.

To the shaft E is attached, atc, a flexible section, K, constructed of wire rope, such as is used for transmitting a revolving motion to dri-lling mechanism, and is well understood by machinists. To the end of this flexible section Kot' the shaft at d is attached a spring-coup ling, L, which couples with the male part M on the fiexible section K attached to the end e of the shaft E. Theconstruction ofthe two parts 6o LA and 'M of the couplingxfor the iiexible sections K, and the operation of said coupling is well understood, and is clearly shown in Figs.

4, 5and 8.

To the locomotive is suspended in pivoted bearings O a shaft, P, on the ends of which are rigidly fixed pulleys Q, having groove j", corresponding in size, depth, and form to the size and contour of the flange of the driving-wheels It, so that the face g of said pulleys will fit the 7o face of' the flange 7L and tread i of the drivingwheels R. The shaft P is furnished with a bevel-wheel, S, which meshes into a bevelwheel, T, the axis of which has its bearing in the yoke U, which is attached to the pivoted hangers 0.

To the axis of the bevel-wheel T is attached a section, V, of the fiexible shafting, used for the purpose of coupling the shaft or shafts E and iiexible sections K with the bevel-wheel T. 8o

To the shaft P is pivoted a yoke, W, suspended by pivoted hangers N', and to said yoke is attached a piston, m, of a steam-cylinder, a, or to a hand-lever for moving forward the shaft P at the will of the operator. l

The skillful mechanic willreadily understand the construction and the relation that the several parts bear to each other from the foregoing descriptiomand by reference to the accom panying drawings, therefore we will proceed 9o to describe the operation, which is as follows:

The operator admits steam to the cylinder n, so that its piston will move in the direction indicated by the arrow j, which will move forward the shaft P and bring the pulleys Q against the driving-wheels It, which will cause the shaft P and its wheel S torevolve, which will revolve the flexible sections V K and shaft E, thereby causing the drum F to Wind on the chain or wire rope Gr, which will draw thebrakclever I so as to apply the brakes to the carwheels with such force as the operator may elect, which, ofcourse, will be in proportion to the traction of the pulleys Q against the driving-wheels R. The springs and gravitation ofthe brake'levers will release the brakes as soon as the draft is taken oil the shaft l.

In the absence of the cylinder n a hand-lever may be employed for moving forward the,

lion, with a revolving shaft or shafts coupled through the medium of exible connections, of -movable mechanism adapted to be thrown into engagement with the rim of the car wheel or wheels, and thereby communicate motion t0 said shaft or shafts, substantially in the manner herein shown and described.

3. In a mechanism for operating the brake lever or levers of brakes for railway'cars, a. revolving shalt or shafts coupled through the medium ofa flexible section of wire rope and coupling L M, substantially in the manner herein shown and described.

4. The shaft P, having pulleys Q and wheel S, in combination with the wheel T, coupled to a shaft or shafts through themedium of a ilexible section, substantially as herein described, and for the purpose set forth.
