Specification of Letters Patent.
Patented Aug. 21, 1906.
Application filed January 19, 1906- Sarial No. 296.765.
To aZZ whom it may concern:
Be it known that I, ALnis H. MARDEN, a citizen of the United States, residing at VVatertown, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Railway-Brakes, of which the following is a specification.
This invention relates to improvements in railway car-brakes, the object of the invention being to provide a strong, durable, simple, and efficient car-brake in which the brake-shoes can be readily attached to or detached from the brake-heads and brakebeam.
The invention consists in the combination and arrangement of parts set forth in. the following specification and particularly pointed out in the claims thereof.
Referring to the drawings, Figure 1 is a side elevation of my improved railway-brake, the brake-beam being illustrated in section. Fig. 2 is a section taken on line 2 2, Fig. 1. Fig. 3 is a section taken on line 3 3, Fig. 1. Fig. 4 is a side elevation of the lever-fulcrum, showing the same attached to the brakebeam with the brake-beam in section.
In the drawings, 5 is the brake-beam, the same being similar to an I-beam structural shape with the exception that the flanges 6 6 are longer than the flanges 7 7 upon the opposite side of the web 8 therefrom.
9 is the brake-head, which is provided with flanges or ribs 10 10, extending around the inner face 11 thereof and projecting into the space between the flanges 6 6, said rib 10 also extending along the upper and lower faces of the brake-beam 5. The brake-head 9 is rendered strong and durable by webs 12, said head being fastened to the flanges 6 by means of rivets 13.
14 is the brake-shoe, which is provided with a lug 15, said lug projecting into the space between the flanges 7 7 of the brakebeam 5. The upper and lower ends of the brake-shoe 14 are reduced in thickness at 16 16 to form ears, and these ears 16 project into slots 17, provided in each of the opposite ends of the brake-head 9 and extending inwardly from the inner face of said..brake head. Akey 18 projects through the slots 17 17 and also through holes 19in the flanges 7 7 and through the hole 22 in the lug 15.
It will be understood that the brake-shoe 14, head 9, and key 18 are duplicated at 0pposite ends, respectively, of the brake-beam 5, to which they are attached. It will be seen that the formation of the brakebeam 5 with the elongated flanges 6 6 gives great strength to the brake-beam to resist any strain that may come upon it when setting the brake, and also the manner of attaching the brake-shoe 14 to said brake-beam forms a very strong and efficient means for the purpose for which it is designed and also a convenient means for attaching said brake-shoe or detaching the same from the brake-beam when combined with the key 18, which attaches said brake-shoe to the brake-bea1n by passing through. the holes 19 in the flanges 7 7 of said brake-beam. Any lateral twist or side pressure is taken by the cars 16, which project into the slots 17 in the opposite ends ofthe brake-head.
A lever-fulcrum 20 is rigidly fastened to the brake-beam 5, said lever-fulcrum being provided with a slot located at an angle to the brake-beam for the purpose of receiving the brake-lever, said brake-lever being pivoted to the lever-fulcrum by a pin 21 in the usual manner and said lever-fulcrum being fastened to the brake-beam midway between the two brake-heads in the usual manner.
Having thus described my invention ,what I claim, and desire by Letters Patent to secure, is- 1. A railway car-brake, comprising in its construction, an I brake-beam, a brakchead fast to said .I-beam, a brake-shoe having a lug thereon projecting between two flanges on said I-beam, and a key, extending longitudinally of said shoe through said lug and flanges, whereby said shoe is attached to said I-beam.
2. A railway car-brake, comprising in its construction, an I brakebeam, a brake-head fast to said I-beam, a brake-shoe having a lug thereon projecting between two flanges on said I-beam, and a key extendin l0ngitudinally of said shoe through said up; and flanges, and through slots provided in the opposite ends, respectively, of said head.
3. A railway car-brake, comprising in its construction, an I brake-beam, a brake-head fast to said I-beam, and provided in the op posite ends thereof with slots extending longitudinally of its inner face, a brake-shoe having a lug thereon projecting between two flanges on said Ibeam, said shoe projecting at its opposite ends into said slots, and a key extending longitudinally of said shoe through said lug and flanges, and through said slots, whereby said shoe is attached to said I-beam.
4. A railway ear-brake, comprising in its shoe, through said lug and flanges, and construction, an I brake-beam, a brake-head through said slots, whereby said shoe is atfast to said I-beam and constructed to protaehed to said I-heain. jeet between the two outer flanges of said In testimony whereof I have hereunto set 15 beam, said brake-head provided in the oppomy hand in presence of two subscribing witsite ends thereof, with slots extending longinesses.
tudinally of its inner face a brake-shoe liavc 1 iug a lug thereon projecting between the two ALDIS MARDEN' inner flanges on said I-beani, said shoe pro- Witnesses:

jecting at its opposite ends into said slots, ANNIE J. DAILEY.
and a key extending longitudinally of said
