BRAKE SHOE Filed March 26, 1924 INVENTOR Patented July 28, 1925.
UNITED STATES PATENT` OFFICE.
BRAKE SCI-ICE.`
Application filed March 26, 1924.l Serial No. 701,883.
To all 'whom t may concern:
Be it known that I, KoNsTANTY ZABINSKI, a citizen of the United States, residing at New Brighton, in the county of Richmond and State of .New York, have inventedL certain new and useful Improvements in Bra-ke Shoes, of which the following is a specilication.
This invention relates to improvements in brake shoes, as used in connection with railroad car wheels and like purposes.
The principal object of this invention is to provide a brake shoe for railroad cars which is so constructed as to materially lengthen the life of a brake shoe.
Another purpose of the invention is to produce a brake shoe which has unusual gripping tendencies and is no-t readily ca.- pable of slipping after application to the wheel.
rlhese and other analogous aims, objects and purposes are attained by the novel construction, combination and arrangement of parts hereinafter described and shown in the accompanying drawing, forming a inaterial part of this disclosure, and in which Figure 1 is a perspective view of a brake shoe made in accordance with the invention, looking from the inner side thereof.
Figure 2 is a transverse sectional view, talren on line 2 2 of Figure 1.
Referring to the drawing in detail, the numeral 10 designates an arcuately formed casing preferably made of sheet metal, having formed at each end at the outer surface of the bach plate 11, inturned lugs 12 adapted to engage with the brake shoe supports (not shown).
A socket 11i is formed centrally at the back 11 of the casing 1() and has an opening l5 through which a. rod or like fastening means may be passed, thereby securing the brale slice at the brake mechanism.
Secured within the casing 10, are segmental blocks 16 of iron or steel having alternately disposed between them similar segmental blocks 17 of carborundum.
These blocks are rigidly held at the front between the downturned flange 18 of the top plate 19 of the casing 10 and the upturned ledge 20 of the bottom plate 21.
At the rear of the blocks 16 and 17 is the back plate 11 secured by screws 22 entering the segmental metal blocks 16.
' The operation of the device will be readily understood as the elements for securing the brake shoe to the brake mechanism have been described as of ordinary construction and are secured in the usual manner, and the shoe itself is applied to the wheel as will be evident.
From the foregoing it will be seen that a device has been disclosed which provides means for readily replacing the worn blocks and also is relatively simple to manufacture.
Not only do the surface of the carborundum inserts form an effective bite on the periphery of the wheel, but these blocks or inserts are held and protected from injury, so that the shoe is unusually long lived.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
1. A brake shoe comprising a curved casing made of sheet metal to present a chamber open at its front concave side and having a raised ledge on the outer edge of its bottom member and a down-turned flange on its upper member, attaching means integral with the rear convex side, a plurality of segmental b-loclrs enterable the chamber from the rear, said blocks being shaped to engage the ledge and flange respectively, and securing means engaging each of said blocks through the rear member of the casing.
2. A brake shoe comprising a curved casing made of sheet metal to present a chamber open at its front concave side and hav.. ing a raised ledge on the outer edge of its bottom wall, and a down-turned flange on its upper wall, attaching means integral with the rear convex wall, plurality of segmental blocks consisting of iron and carborundum arranged in alternate relation to fill the space in the chamber and engage the ledge and flange thereof, and to extend outwardly therebeyo-nd, and securing means passing through the 'rear wall of the casing to engage in each block.
In witness whereof I have aliixed my signature. J
KOFNSTANTY ZABINSKI.
