WITNESSES:

ATTORNEY WILLIAM HESTON, OF ALLIANCE, OHIO.

CARHBRAKE.

SPECIFICATION forming part of Letters Application filed September 14,

To all whom it may concern:

Be it known that I, WILLIAM. HESTON, a citizen of the United States, and a resident of Alliance, county of Stark, State of Ohio,have invented a new and useful Improvement in Gar-Brakes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in car-brakes; and it consists in certain features of construction and combination of parts, as will be hereinafter described, and set forth in the claims.

Figure 1 is an isometrical view of a cartruck illustrating my invention. Fig. 2 is a side elevation of said truck under car and tender, showing one way of operating brake.

Similar letters of reference indicate corresponding parts in the accompanying drawlugs.

Letter A represents the truck-wheels, and B the axles, which may be of any of the wellknown and approved kinds.

The frames() may be either made of wrought iron or steel, and are provided at each end where the axles of the truck-wheels are journaled with oil-boXes D. nected by the girders E.

The feature of my invention consists in providing a brake for car-trucks, whereby the ordinary brake-beam, the cause of so many accidents, resulting in the loss of life, as well as vast amounts of money by the destruction of property, may be eliminated and a brake formed of parts as hereinafter described, and so located and attached to the top of the girder E as to secure them from liability to become detached and fall upon the track, and consists of the bars F and G, crossing each other and pivotally secured to the girder, as shown in Fig. 1. The central portion, d, of the upper bar, G, is raised, as shown, for the purpose of overlapping the lower bar, F.

A brake-block, H, and shoe, of any of the wellknown and approved forms, may be pivotally secured to the outer ends of the bars F and G, as shown, whereby the shoes may be moved to and from the wheels on a line tangent thereto, for the purpose hereinafter stated.

To secure the outer ends of the brake-bars These frames are con- Patent No. 391,470, dated October 23, .1888.

1887. Serial No.249,610. (NomodeLl F and G from vertical movement, the crossbars M and N are provided, as shown, bolted together in their middle portion and to the girder, the outer end of the upper bar, N, raised so as to allow the ends of the brakebars to move freely on a line to and from the wheels, and at the same time restrain them from vertical movement.

A spring, 0, as shown, is provided for the purpose of drawing the brake-shoes back and releasing the wheels.

For the purpose of bringing the brake-bars into action, draw-bars J are provided, having one end pivotally secured to the bars F and G, the other end secured in a clevis or link, K, to which the draft-cord L is attached, and the other end of the said cord connected to the usual chain and Windlass provided for handbraking cars; or the brake-rods of the entire train may be connected, as shown at P, Fig. 2, and then connected to a piston-rod projecting from a piston-head in the steam-cylinder R, suspended under the tender S. The said steamcylinder is provided with a pipe, T, connecting with boiler of thelocomotive, and a threeway cock,U,operated by an upwardly-projecting rod,V. The cylinder R is open at its front end. The steam admitted at the rear end will drive the piston-head forward to set the brakes. To release the brakes, the steam-cock is turned so as to close the communication with the boiler and open a way from the cylinder out into the open air; or, if preferred, the pipeT may be connected to an air-drum and the piston operated by compressed air instead of steam from the boiler, as hereinbefore stated.

Having thus fully stated the nature and object of myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination, brake-bars secured to a suitable support, shoes pivoted to the ends of said brake-bars, draw-bars pivotally secured to the brake-bars to swing their ends in opposite directions, an open-ended cylinder, a piston in the cylinder, a flexible connection between the piston and the draw-bars, and a supp1y-pipe for steam or compressed air to actuate the piston, said steam-supply pipe having communication with the cylinder at a point between the piston and the drawbars, substantially as set forth.

2. A car-brake composed, essentially, of

ICO

brake-bars F and G, centrally crossed and pivotally secured to the girder E,and having shoesupporting blocks pivotally secured to their outer ends, and draw-bars J, pivotallysecured to the brake-bars and to a clevis or link and a draft-cord, substantially as described, and for the purpose set forth.

3. The combination of the brake-bars F and G, draw-bars J, shoe-supporting blocks H,and

springs O, substantially as described, and for the purpose set forth.

4:. The combination, in a car-truck, of the crossgirder E, the brake-bars supported thereon and centrally pivoted thereto in the form of an X, and having on their outer ends shoe-supporting blocks, and draw-bars J, pivotally secured to said brake-bars F and G and to a draft-cord by which the shoe-block may be operated in opposite directions, substantially as shown and described, and for the pur- 2o pose set forth.

5. The combination, with the girder E of a car-truck, of the brake-supports consisting of the cross-bars M and N, bolted together at their middle portion. and to the said girder, and bifurcated at the outer ends, one prong passing under and the other over the brakebar,whereby a vertical movement is prevented and the brakes held in their proper working position, substantially as described, and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 9th day of August, A. D. 1887.

WVILLIAM HESTON.
