SPECIFICATION forming part of Letters Patent No. 225,611, dated March 16, 1880. Application filed January 524, 1880.

To all whom it may concern:

Be it known that I, JOHN R. JONES, of Glarksville, in the county of Butler and State of Iowa, have invented a new and useful Improvement in Railway-Oar Brakes, of which the following is a specification.

The object of my invention is to give to the engineer of a train full control of the brakes without interfering with their operation by hand on each car; and the invention consists in a pronged lever hung at each end of each car, the levers on each car being connected together and to the brake-chains, and the levers being fitted for continuous contact throughout the train, so that when the brakes are ap plied on the tender by power from the engine there is a continuous or successive application of the brakes from the first to the rear car.

My invention consists, also, in certain details of construction whereby I obtain facility of operation, all of which will be particularly described with reference to the accompanying drawings, forming part of this specification.

In the drawings, Figure 1 is a side elevation of a locomotive and tender, showing the mechanism for operating the brakes. Fig. 2 is an inverted plan view of the tender, and Fig. 3 is a vertical longitudinal section of the same. Fig. 4 is an inverted plan view of a car as fitted with my improvement. Fig. 5 is a vertical longitudinal section, and Fig. 6 an end view, of the car.

Similar letters of reference indicate corre sponding parts.

A is the locomotive, B the tender, and O a car. All the cars of a train will be fitted in the same manner as the car 0. a a in all the figures are the usual brakes; b b, the brake-levers; c c, the rods and chains, and cl the handwheels for operating the brakes in the usual manner.

Upon the locomotive A is a winding drum or shaft, 0, carrying a friction-wheel, f The shaft 6 is hung in fixed bearings at one end, and its end carrying the wheel f is hung on the lower end of a lever, 9, that is fulcrumed in a hanger at the side of the locomotiveframe, so that by movement of lever g the wheel f is thrown in or out of contact with one driving-wheel of the locomotive. From the winding-shaft e a chain, It, passes to a winding-drum, i, that is fitted beneath the tender B, either on the shaft of handwheel d or as shown, and to obtain more power the drum z'is fittedin separate bearings, and gears with a pinion, t, on the hand-wheel shaft.

This construction permits the brakes to be applied by power from the driving-wheel, or by hand by operation of the hand-wheel.

To the shaft of the drum i is connected a chain, k, that passes to the brake-rod o, and upon the opposite end of the tender is hung a lever, on, from the lower end of which a rod, 022 extends to about mid-length of the tender, and is connected to the brake-rod 0.

Upon the opposite ends of the car 0 are hung levers m, which are connected together at their lower end by a rod, n, and one lever m is connected by a chain, 0, to the brake rod 0 of the car G.

The lever in of the tender B and levers m of car 0 are similar in construction, and are formed with the upper portion spread orforked,

to give a broad bearing of the lever-on one car with that on the next and insure contact in case the cars sway sidewise.

The levers m m are to be hung directly on the ear-frame, or to the bolsters of the trucks beneath the draw-heads, and thus serve as means for transferring the motion of the brakerods of one car to the car next behind, the operation being the same whichever end of the car is forward.

In operation, if the engineer desires to brake the whole train, it is only necessary to apply the brakes of the tender by hand or power, as described, which sets the lever m with its upper end projecting backward, and the forward lever in of the first car is thereby moved and the brakes of the car applied, and the movement again transferred by the rear lever m to the next car, and so on to the end of the train, and as the cars close together the brakes are tightened. Thus the brakes on 5 each car are tightened as required, after the first movement, independently of the tender, a continuous chain throughout the train is not required, and the only motion required is the initial movement of setting the brakes of the tender. The brakes are freed by slackening the tender-brakes, and the contact of the levers tends to keep the brakes free until it is desired to set themagain. This construction permits the brakes on each car to be operated as usual when desired.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent 1. In mechanism for operating car-brakes, the levers on m, hung at opposite ends of the cars, and connected together and to the brakerods, whereby the brakes of the cars are applied by contact of the levers with similar levers upon the tender or next car substantially as shown and described.

2. ln car-brakes the combination with the brake mechanism and hand-wheels for operating the same, of the levers m, hung at opposite ends of the cars, and connected with the brake-rods whereby all the brakes of a train train, substantially as described and shonXi 3. In car-brakes, the lever g, shaft 6, chain h, and friction-Wheel f, fitted on the locomotive, in combination with the brake mechanism of the tender and cars, and the levers m m, for giving simultaneous movement to all the brakes of the train, substantially as described and shown.

4. The windingdrum '6, chain 70, and pinion t, combined with the hand-wheel and shaft d, the brake mechanism of the tender, and the lever m, for giving simultaneous movement to the brakes of the adjacent car substantially as described.
