RAIL-BRAKE.
SPECIFICATION forming part of Letters Patent No. 794,862, dated July 18, 1905.
Application filed December 2'7, 1904. Serial No. 238,469.
To all whom it may concern.-
Be it known that I, MORTON HATTERY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Rail-Brakes, of which the following is a specification.
This invention is a rail-brake arranged to be operated by fluid-pressure. It is particularly suitable as an emergency-brake for use on locomotives, but may be used on any kind of rolling-stock having fluid-pressure.
The object of the invention is to form a simple and powerful device of the kind characterized by improvements, as will more fully hereinafter appear.
In the accompanying drawings, Figure 1 is a side elevation, partly in section, of the brake. Fig. 2 is a side elevation with the face-plate of the guide-casing removed. Fig. 3 is a vertical cross-section.
Referring specifically to the drawings, 6 indicates a stout guide-casing for the slide 7 which works up and down therein. This casing is bolted or otherwise firmly secured to the car or truck-frame 8 and is further supported by braces 9. The front plate of the casing is removable, as shown in the drawings, said front plate being indicated at 10, secured by bolts 11. The casing extends downwardly from the car-frame toward the rail of the track (indicated at 12) and holds the slide in such position that the brake-shoe carried thereby will bear upon the track when depressed.
The slide 7 has an outwardly-projecting lug 13, which extends through an opening 14 in the face-plate 10. 15 is a level which is pivoted at 16 to one of the braces 9 and extends over and upon the lug 13. At the other end the lever is connected by a rod 17 to the piston 18 in the cylinder 19, arranged to receive fluid-pressure under suitable control through a pipe 20.
At its lower end the slide 7 has an elongated foot 21, disposed lengthwise with respect to the rail, and this foot carries the brake-shoe 22, which is preferably serrated, as at 28, to take better hold on the rail. The brake-shoe is attached by lugs 24, which extend through openings in the foot and secured on the upper side by wedge-keys 25. The brake-shoe has a silde flange 26 to assist in holding it to the rai The slide is normally lifted by springs 27 which are located in recesses therein and rest upon lugs 28, projecting from the walls of the easing into said recesses.
The operation is evident. hen fluid-pressure is admitted into the cylinder, the piston is forced down and the lever bearing upon the lug 13 forces the slide down and the brakeshoe against the rail. A powerful braking action is thus effected. When the pressure is let off, the springs27 restore the parts.
What I claim as new, and desire to secure by Letters Patent, is
In a car-brake, in combination, a casing carried by the car and having an opening in one of its walls, a slide movable up and down in the casing and having a lug projecting through the opening, a brake-shoe secured to the foot of the slide, and an operating-lever bearing upon the lug.
In testimony whereof I. have signed my name to this specification in the presence of two subscribing Witnesses.
NIORTON HATTERY.
