WILLIAM NV. LOOMIS, OF \VILKESBARRE, PENNSYLVANIA.
Letters Patent 1v 95,699, dated October 12, 1869.
IMPROVED RAILWAY-BRAKE.
The Schedule referred to in these Letters Patent and making part of the same.
novel and improved Method of Constructing and Applying Brakes to Railroad-Oar Wheels and -I hereby declare the nature of my said invention, and in what manner the same is to be constructed and applied to one or more wheels of a railroad-car at the same time,
by means of any of the many mechanical devices employed to operate car-brakes, as particularly described and set forth in and by the following statement, reference being bad to the accompanying (h'awings, which are lettered to correspond with and form a part of the specification.
" in order that the public may fully understand the A nature of my invention,- and those who are skilled in the mechanic art of railroad-car building, construct and apply the same, I will describe it-as follows, to wit:
Plate 1 is a perspective drawing of a railroad-car, having my revolving brakes 01' wheels A A applied to the hind wheels, 2 and 4, of the car. B B is an adjustable transverse bar, moving parallel to the axletrce of the car,.in the slots n u, by means of chains or wire rope c c 0, operated by the brakeman, at K, at the front end of the car, and the-wheels A A revolve upon the transverse bar B B, and are carried out of contact with the car-wheels 2 and 4, by the action of the elastic springs s, secured in the slots or horizontal openings at n, in front of the adjustable bar or axesB B, to force the brakes A A clear of the car-wheels, at the pleasureof the brakemarn Plate 2 is a side elevation of a railroad-car, having a smaller brake-wheel, A, held down upon the rail R and in contact with the treading-periplrery of the front wheel 1 of the car, by means of a stiff spiral or other suitable spring, s, operating the diagonal rod N, which is secured to the transverse axle-tree B of the brake-wheels A, at the lower end, and connected, at its upper end, to the chain which passes over the pulley l, and around the reel or base H of the brakehandle, which, in this instance, is employed to relieve or take the brake-wheel off the track R and out of contact with the car-wheel l, by drawing the axle-tree B up the inclined groove '01 slot a, as shown at plate I). heel or brake A" may be provided with agroove upon the outer periphery or bearing-surface, as shown at G, plate 4, so that an increased amount of friction is produced upon the hearing or treading-srn'face of the wheel 1' of the car, when the brake A is forced in contact with the same by the spiral or other spring 8', when set free by the brakernan operating the bandle K.
Plate 4 represents the treading-surface of the brakewheel A", showing the groove G, which receives the flange of the car-wheel 1, if thought best to increase the friction and prevent the lateral sliding ofthebrake-wheels A or A A; yet, I believe a simple, plain-surfaced wheel, A, when properly arranged and applied as a brake for stopping a railroad'car, is the most efioctual and surest means ever employed for such purposes, I
Therefore, the novelty of my invention consists in the application and use of one or more revolving brake-wheels A, A, and A, mounted upon the adjustable axis B, so that the said brakes A, A, or A", may be brought in contact with thetreading-surface of the car-wheels, (next the brakes) by means as above set forth, or by any other device that will force the brakewheels A, A, or A", in contact with the revolving carwlreels upon the track R, thereby reversing the action of either the brakes or the car-wheels themselves, which I believe to be equivalent, in effect upon the moving train, to reversing the engine.
Finally, I believe the whole arrangement of the above apparatus produces less wear upon the rails and wheels of the car, than any other brake ever employed for the purpose set forth. Therefore,
What I claim as novel and useful, and what I wish to secure by Letters Patent of the United States, is-
llre revolving brake-wheels A, A, or A, at either or both ends of araih'oad-car, mounted uponthe ad-, justable axle-tree B, to operate upon the car-wheels l, 2, by means of tlre slots.'u or a, suitable springs s s" vrire ropes or chains 0 c c, or by any other suitable devices employed for working car-brakes.
In testimony whereof, I hereunto subscribe my name in the presence of two witnesses.

Witnesses JOHN S. Looms, J muss P. MCLEAN.
