BRAKE FOR CARS- SPECIFIGATION forming part of Letters Patent No. 757,910, dated April 19, 1904.

Application filed September 10, 1903- Serial No. 172,675. (No model.)

To all whom it may concern/.-

Be it known that I, WILLIAM Gossn'r'r, a citizen of the United States, residing at Falls City, in the county of Richardson and State of Nebraska,have invented new and useful Improvements in Brakes for Cars, of which the following is a specification.

My invention relates to new and useful im-' provements in brakes for cars; and its object is to provide brake-shoes of novel construction and arrangement, which are adapted to be operated in any desired manner and which can be connected to brake-operated mechanism of ordinary form.

Another object is to provide shoes which will act simultaneously upon the wheels of a car and therails upon which they are mounted, thereby bringing the car to a quick stop, if desired.

With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts, which will hereinafter be more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which Figure l is a side elevation of a portion of a car and showing my improved brake in normal position and removed from contact with the wheels and rails. Fig. 2 is a similar view showing the brake-shoes applied. Fig. 3 is a top plan view of the brake mechanism, the car body and truck being removed; and Fig. 4 is a detail view of a brake-shoe.

Referring to the figures by numerals of reference, l 1 are hangers in which is journaled a transversely-extending shaft 2, having an arm 3 extending therefrom, which is adapted to be connected to suitable brake-operating mechanism 4. To the ends of this shaft 2 are secured arms 5, which are connected to links 6. These arms support a rod 7, which extends transversely of the car and is provided at its ends with depending blocks 8, which are wedge-shaped in elevation. Loosely mounted upon the rod 7 directly above each block 8 are oppositely-extending arms 9, provided at their outer ends with angular extensions 10, having concaved outer faces 11, which are shaped to conform to the contour of the peripheries of the wheels. These-extensions may be formed integral with or separate from the arms 9, and detachably connected to the lower face of each extension is a shoe 12, the lower face of which is shaped to conform to the contour of the head of a rail. The ends of these shoes are curved, as shown at 13, so that only a smooth surface will be presented to the rail when the shoes are applied thereto. The arms 9 are normally supported by the block 8 with the shoes 12 removed from contact with the rails and the extensions 10 out of contact with the wheels 14: of the car. I have shown these positions of the shoes in Fig. 1. When it is desired to apply the brake, the shaft 2 is partly rotated by the mechanism 4, so as to swing the arms 5 downward. This will move the links downward toward the rails 15, on which the wheels are located, and-the shoes 12 will thus be brought into contact with the said rails and will be slid in opposite directions thereon until the concaved faces 11 of the extensions 10 are brought into contact with the peripheries of the wheels 14.

It will be seen that by means of this brake the car can be brought to an immediate stop, provided suificient downward pressure is exerted upon the arms 9, which firmly bind the extensions 10 and shoes 12 upon the wheels and rails, respectively.

The brake is very simple in construction and can be readily attached to ordinary brakeoperating mechanism. As it operates simultaneously upon the wheels and rails, sliding of the car after the brake has been applied is prevented.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as may fairly fall within the scope of my invention. I

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A car-brake comprising a rotary shaft having arms extending therefrom, supportingblocks suspended from the arms, oppositelyextending arms pivoted above and normally supported by the blocks, and brake-shoes at the ends of the arms adapted to be simultaneously applied to the wheels of a car and the necting the rod with the arms, blocks extending' from the links, oppositely-extending arms pivoted upon the rod and normally supported by the blocks, and shoes at the ends of said arms adapted to be simultaneously applied to the peripheries of car-wheels and the rails upon which they are mounted. 1

4- In a car-brake the combination with a revoluble shaft; of an arm extending therefrom, a link connected to the arm, a block secured to the link, oppositely-extending arms pivoted above and normally supported by the block, an angular extension to each arm having a concaved working face adapted to contact with the periphery of a wheel, and a shoe detachably secured to the extension and adapted to contact with a rail and form a fulcrum for the extension.

5. In abrake, the combination with a revoluble shaft having arms extending therefrom; of a rod, links connecting the rod and arms, blocks extending from the links, oppositelyextending arms pivotally mounted upon the rod and normally supported by the blocks, angular extensions at the ends of said arms and having concaved working faces, and shoes detachably secured to the extensions and adapted to contact with rails.

In testimony whereofI'aflix my signature in presence of two witnesses.
