BRAKE-SHOE.

Specification of Letters Patent.

Patented Aug. 14, 1906.

Application filed December 22, 1905. Serial No. 292.929.

5 New York, have invented certain new and useful Improvements in Brake Shoes, of

which the following is a specification.

Thisinvention relates to an improved reinforced railway brake-shoe; and it consists [o of a body and at least one reinforcement in' said body Which extends approximately vertic ally and longitudinally therein.

The main object of the invention is to strengthen the shoe sufficiently to obviate in I5 a great measure the danger of breaking the shoe while in use.

The invention also relates to certain details of construction, all of which will be fully and clearly hereinafter described and claimed,

zo reference being had to the accompanying drawings, in which- Figure l is a vertical longitudinal section through the improved brake-shoe on line a a, Fig. 5. F' 2 is a vertical longitudinal secthe improved brake-shoe on line b b, Fig. 5. Fig. 3 is a horizontal longitudinal section cutting through the improved brake-shoe on the curved line c c, Fig. 2. Fig. 4 is a horizontal longitudinal section through 3o the improved brake-shoe on the curved line i-ffFig. 1. Fig. 5 is an enlarged vertical "/transverse section through the improved brake-shoe on line e e, Fig. l.

The adaptation of the invention shown in 3 5 the accompanying drawings comprises a body l, cast of iron in the usual Way and having a curved braking face or surface 2, at least one longitudinal reinforcement 3, which is approximately horizontal except that it 4o curves in correspondence with the shoe and extends through the upper portion thereof, and at least one longitudinal reinforcement 4, which is approximately vertical with its upper edge in proximity to the horizontal reinforcement 3, and its lower edge extending to and through the braking face or surface of the shoe-body.

Preferably two horizontal reinforcements 3 are employed, and each of said reinforcements 5o is provided with a series of openings or slots 5, in which portions of the cast metal of the body fit and interlock to rigidly fasten the reinforcement in place in the body. The vertical reinforcements 4' are likewise provided with a longitudinal row of openings or slots and in which portions of the cast body also fit and interlock.

Three of the vertical reinforcements 4 are preferably employed, although this number is not absolutely essential, as more or less can be used, if desired.

When three of the vertical reinforcements are used, they are located so that one extends through approximately the longitudinal center of the shoe-body from the braking-face vvertically up to between the two horizontal reinforcements 3, and the other two extend on opposite sides ofand parallel to the said central 'vertical reinforcement from the braking-face into proximity to the outer edge of the horizontal reinforcements 3.

The vertical reinforcements 4 may be made short enough to terminate near the ends of the shoe-body in the manner shown in the 75 drawings, or they may be long enough to extend through the ends of the body.

The vertical longitudinal reinforcements not only additionally strengthen the shoe, but also serve to lessen the friction by having their lower edges extend through the braking-face and form portions of said brakingface. By this means the braking-face is divided into longitudinal sections of differing and contrasting metals, some of which are smoother and less frictional than others. The reinforcements are preferably pressed or otherwise formed of sheet metal, although they may be made of any other suitable metal in any other desirable manner.

It should be noted that the reinforcements are curved to correspond with the curve of the body, the horizontal reinforcements 3 having curved faces and the vertical reinforcements 4 having curved edges.

I claim as my inventionl. A brake-shoe having a cast body and a straight vertical longitudinal reinforcement in said body surrounded on all sides with the exception of its bottom edge by the cast .metal of the shoe.

forcement extending longitudinally in said 11o 6, which are located near the top edge thereof IOO body and completely surrounded with the exception of its bottom edge by the cast metal of the body said reinforcement having a series of openings in Which portions of the metal of the body lock.

4. A brake-shoe having a cast body, a plurality of longitudinal reinforcements, one of Which is approximately vertical and another of Which is approximately horizontal.

5. A brake-shoe having a cast body, a plurality of longitudinal reinforcements, one of Which is approximately vertical and another of which is approximately horizontal, and each having a series of openings in Which portions of the metal of the body lock.

6. A brake-shoe having a curved cast body and a plurality of comparatively thin reinforcements, one of Which is curved horizontally and another of Which is curved verti- 1(aly in correspondence with the curve of the 7. A brake-shoe having a cast body, a plurality of longitudinal reinforcements, one of Which is approximately vertical and another of which is approximately horizontal, and each being curved in the same direction.

8. A brake-shoe having a cast body and a comparatively thin reinforcement of uniform Width and flat sides in said body extending longitudinally at least nearly from end to end of said body and vertically from the bottom braking-face to near the top surface of the body.

9. A brake-shoe having a body, two approximately horizontal longitudinal reinforcements embedded side by side in said body near the top thereof, and three parallel vertical longitudinal reinforcements embedded in said body. y

10. A brake-shoe having a body, and a plurality of thin, flat-sided vertical longitudinal reinforcements embedded in said body; said reinforcements being entirely unconnected.
