To @ZZ whom it' may concern:

Be it knownthat we, ROBERT A. BURCH and ALEXANDER B. WINFREE, citizens of the United States, residing at Paducah, in the county of McCracken and State of Kentucky, have invented cer-tain new and useful Improvements in Brakes for Railway-Cars; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to friction-brakes for railway-cars and it consists of certain devices herein described and claimed.

Reference is had to the accompanying drawings, wherein the same parts are indicated by the same letters.

Figure 1 represents a side elevation of theV lower part of a car fitted with oury device, parts of the carttings being removed. Fig. 2 represents a plan View of the same, the carbody being removed.

A ,A2, A3, andA4represent the brake-beams B, the brake-shoes; C, the car-wheels; D and D the brake-levers attached to the outer brake-beams on each car.

E represents a lever supported at one end in the bracket E and pivoted at the other e beneath the car. c2 represents a slot in the said lever to which the piston f of the brakecylinder F is attached. This piston may be pushed out by the admission of compressed air or steam into the cylinder F.

G, G3, G3, G4, and G5 are rods, while G6 and G7 are chains. The chain G6 may be attached to either of the rods G2 or G3 and passes over a pulley upon the opposite rod. Ve have shown it attached to the rod G2, passing over the pulley g3 on the rod G3, and having its other endsecured to the end e3 of the lever E. The rod G5 is also attached to the said chain at any convenient place g5, preferably about half-way between g3 and e3, while the chain G7 connects the other end of the rod to the brake-staff H, which is actuated by the hand-wheel h.

T represents one of the bottom timbers of the car, and T the platforms.

The operation of our device is as follows: If it be desired to work the brakes from the locomotive, air or steam is admitted to from the locomotive.

the brake-cylinder F by means of suitable flexible connections, (not shown,) such as are now generally in use. If itbe desired to work the brakes by hand, turn the hand-wheel 7L and brake-staff l-l. In either case the chain G6 is pulled around the pulley g3, and the rods `-G3 and G and G3 and G4 are drawn in the the hand-wheel and the brake-cylinder attachments We provide a simple and effective means of applying the brakes Whether the car ybe coupled up in a train or be detached Moreover, by the eX- treme simplicity of our device the lost motion and loss from friction in actuating the various parts are made very small.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, is-

1. In a system of friction-brakes for railway-cars, the combination, Vwith the brakebeams A, A2, A3 and A4, having brake-shoes B, of rods G and G4, connectedv to the inner brake-beams, the levers D and D3, connected to the outer brake-beams and to the said rods, the rods G2 and G3, connected at their outer ends to the said levers, a chain and pulley connecting said rods at their inner ends, and means for pulling on said chain and applying said brake-shoes to the Wheels of the car, substantially as described.

2. In a system of friction-brakes for railway-cars, the combination, with the brakebeams A, Af A3 and A4, having brake-shoes B, of rods G and G4, connected to the innery brake-beams, the levers D and D3, connected to the outer brake-beams -and to the said rods, the rods G2 and G3, connected at their outer ends t0 the said levers, a chain and pulley, connecting said rods at their inner ends, a lever pivoted beneath the car and connected IOO to the said chain, a piston attached to said lever, and a cylinder inclosing said piston, with means for admitting air or steam into said cylinder, substantially as described.

3. In it system of friction-brakes for railway-cars, the combination, with the brakebezuns A', A2, A3 and A4, having brakeshoes B, of rods G and G", connected to the inner brake-beams, the levers D and D2, connected tothe outer brake-beams and to the said rods, the rods G2 and G3, connected at their outer ends to the said levers, a chain and pulley connecting,` said rods at their inner ends, a

rod leading from the said chain and pulley t0 one end of the car, a chain attached to the said rod, and L brake-staff for winding` up said chain and applying the brakes by hand, substantially as described.

In testimony whereof We afiix ou r signatures in presence of two witnesses.
