To all whom it may concern: Be it known' that I, J OHN J. MORSE, a c tizen of the United States, residing at the city of St. Louis, State of Missouri, have inventserial No. 715,707 which resulted in Patent No. 1,095,019, dated April 28, 1914.

This invention relates to new and useful improvements in brake-shoes, and has for its object to provide a brake-shoe which is composed of relatively hard and soft metals in order to obtain increased frictional and wearing qualities and at the same time to increase the strength and longevity of the brake-shoe.

In the accompanying drawings forming part of this speclfication, in which like numbers of reference denote like arts wherever they occur, Figure 1 is a transverse sectional view of a brake-shoe embodying the present invention; Fig. 2 is a sectional view on the line 22, Fig. 1; Fi 3 is a plan view of the pattern of the rein orcing element; Fig. 4 is a transverse sectional view of a brakeshoe having an alternate form of reinforcing element located therein; Fig. 5 is a sectional view on the line 55, Fig. 4; and Fig.

6 is a plan view of the pattern of the reinforcing element, which is used in the structure depicted in Figs. 4 and 5.

The brake-shoe 1 is preferably formed of.

cast-iron and is reinforced by a plate 2 of wrought, ductile, or other tough metal, which plate is preferably located near the back of the brake-shoe and is arcuated simi-- larly to the back of the latter. The plate 2 bears a plurality of arms 3, some of which arms project from one side of said plate and others project from the opposite side of said plate, the arms 3 borne by one side of the plate 2 being spaced apart and arranged in staggered relation with respect to the arms 3, which are borne by the other side of said plate and are, also, spaced apart, as best seen in the patterns of said plate depicted in Figs. 3 and 6. The arms 3 are bent so as to extend diagonally through the body of the brakeshoe from opposite sides of the plate 2, so

that the arms 3 borne by one side of said plate extend between the arms 3 borne by the other side o-f'said plate, and, by this air rangem ent, not only anchor the plate 2 firmly 1n the cast-metal of thebrake-shoe, but increase the frictional qualities of the wearing part of the brake-shoe. Said arms 3 may be ofsuch length that same will extend substantiallv straight from the sides of the plate 2 diagonally through the body of the rake-shoe to a point near the wearing face of the latter, as depicted in Figs. 1 and 2,

or, if desired, said arms may be relatively long, in which case each arm 3 is bent at the point 4 intermediate the end of said arm and its point of juncture with the plate 2, so that'the part extending between the bend 4 and the ]11I1Ct111e Wlth the plate 2 diverges toward said'plate, and the part extending from the bend 4 to the end of said arm diverges toward the wearing face of the brakeshoe, as depicted in Fi s. 4 and 5. It should be understood that, i desired, the arms3 may be still longer and provided with more bends 4 than shown in Figs. 4 and 5.

The brake-shoe may be provided with the usual key lug 5 having the usual opening 6 therein or with a plurality of such key lugs, which lug or lugs may or may not be reinforced.

Itwill be evident that the wrought orductile reinforcing plate not only increases the strength of the brake-shoe, but the presence of parts of same in the wearing part of the brake-shoe enhances its braking qualities and thereby increases the longevity of the brakeshoe. By reason of using a plate having .arms 3 as hereinabove described, the disposionly may extendinto and form part 'of the wearing face of the brake-shoe, but may take I the place of the inserts ordinarily .used. In

this way the plate at or adjacent to the back of the brake-shoe is combined with the arts of same that may take the place 0 mserts in the wearing part of the brake-shoe, the result being the: provision of a stronger and; more efiicient brake-shoe.

I claim:

1. A brake-shoe having a body portion including a wearing member which extends toward'the wearing face of the shoe in an obli uely transverse direction, said wearing mem er bein of dilferent material from other materia forming a part of the said body.

2. A brake-shoe having a body portion including a. plurality of wearin members which are angularly disposed wit respect to v each other and which extend toward the wearinig faeeof the shoe in obliquel transverse irections, said wearing mem ers being of different material from other material forming a part of the said body.

3. A brake-shoe having a body portion composed of a plurality of materials one of which is a tough metal and the other of which is a granular material, said body portionincluding members of the tough metal which are embedded in the anular material and which extend towar the wearin face of the shoe in transversely oblique d1- rections. v

e 4. In a brake-shoe, a plate of ductile metal located adjacent to the back thereof, said plate having extensions which are connected to the longitudinal sides of the plate and project therfrom into the wearing part of the brake-shoe, the free end portions of the extensions terminating at points located adjacent to the longitudinal side of the plate opposite to the longitudinal side to which the extensions are connected.

5. A reinforced brake-shoe com osed of east-metal and having a plate 0 ductile metal located adjacent to the back thereof and arms borne by said plate and projecting Boat-ransversely from the longitudinal sides of same into the wearing part of the brakeshoe, the arms borne by one side of said plate being arranged in staggered relation with respect to the arms borne by the other side of the said plate and terminating at opposite sides of the plate.

6. A reinforced brake-shoe com osed of thelongitudinal sides of said plate into the wearing part of the brake-shoe and which are of a length substantially equal to the width of the plate.

7. A reinforced brake-shoe composed of cast-metal having a plate of ductile metal located adjacent to the back thereof, said plate bearing a plurality of arms which tproect transversely in spaced relation rom the sides of said plate into the wearing part of the brake-shoe, the arms borne by one side of said plate being arranged in staggered relation with respect to the arms borne y the other side of said plate and extending between same in the wearing part of the brake-shoe.

8. In a reinforced brake-shoe, a plate hav ing transverse parts which extend from the opposite longitudinal sides thereof toward each other and toward'the wearing face of the shoe and which are of a length substantially equal to the width of the plate.

9. In a reinforced brake-shoe, a reinforcement therefor consisting of intersecting parts transversely disposed with relation to the shoe and extendin from opposite sides of the shoe toward tie wearing face thereof and in opposite inclined directions alrlid terminating at opposite sides of the s 0e.

10. In a brake-shoe, a reinforcement ing from opposite sides of the shoe toward the wearing face thereof, said parts crossing one another.

11. In a brake-shoe, a reinforcement therefor consisting of parts transversely disposed with relation to the shoe and extending from opposite sides of the shoe toward the wearing face thereof, the outer ends of said parts terminating at the sides of the shoe opposite to the shoe side adjacent to which latter the inner ends of the parts are disposed.

12. In a brake-shoe, transverse intersecting reinforcements therein.

13. In a brake-shoe, reinforcements which extend toward the wearing face of the shoe and intersect each other at points between the wearing face and the back of the shoe.

14. In a brake shoe, a plate having a series of arms on each side thereof, the arms on one side of the plate crossing the arms on the opposite side of the plate at points intermediate the ends of the arms.

15.In a brake shoe, sinuous reinforcements, portions of which intersect one another.

, 16. In a brake shoe, a plate and a sinuous extension connected to each side of the plate and being disposed beneath the plate and extending toward the wearing face of the brake shoe.

17. In a brake shoe, a plate and a sinuous extension connected to each side of the plate, plate, at a multiplicit of oints between the extension on one side of the plate interthe back and wearing ace 0 the shoe. 10 seating the extension on the other side of In testimony whereof I hereunto afix my the plate. signature in the presence of two witnesses.

18. In a brake shoe, a plate and a sinuous JOHN J. MORSE. extension connected to each side of the plate, Witnesses: the extension on one side of the plate inter- GEORGE G. ANDERSON,
