BRAKE SHOE `Filed oet. 29, 1928 n Y MP1 `ATTORNEY Patented June 7, 1932 UNITED sIAIEs PATENT OFFICE.

OWEN R. lSKELTCN, oF DETROIT, MICHIGAN, AssIGNoR To CHRYSLER CORPORATION,

oF DETROIT, MICHIGAN, A CORPORATION or DELAWAREy l BRAKE sIIbE Application filed October 29, 1928.v Serial No. 315,744.

ject of the invention is to provide inexpensiveA means for forming a metal .brake shoe; More speciically stated the linvention con- ,sists in forming the shoe by uniting two members, preferably by casting one of the [members to the other and providing a tight :o \bond between the two united members.

These and other objects and features of the invention willV more fully appear from the following description taken in connection with 'the accompanying dra-wing in which:

Fig. 1 is a vertical section through a brake, just inside the wheel, showing the shoe in side elevation and the operating mechanism for/the brake in section.

' Fig. 2 is a side view of the shoe, parts' being broken away and in section.

Fig. 3 isa view of the shoe at right angles to Fig. 2.

Fig. 4 is a sectional view vtaken on line 4 4 @f Fig. 2.

5 Fig. 5 is a sectional view taken on line 5 5 of Fig. 2. I

Fig. 6 is a perspective of aportion of the shoe, parts being broken away and. in section.

. illustration, a brake including adrum 10, Yanchor plate 12 and operatingy mechanism 14 are conventionally shown. A pair of brake shoes 16 are pivoted as at 18 to the anchor plate 12 and are operated bythe operating mechanism 14 which consists 'of a'pair of oppositely movable cylinders 20 forced apart by thetwo members forming a T shaped rigid In the form of my. invention'selected for' is moulded toJthe outer edge of theplate 16,

shoe construction to which the friction ma.- terial may be applied. The outer edge of the plate 16 is irregular to form a better bond between the two members 16 and 20. In the form illustrated dovetail projections 24 are embedded in the flange 22. At the center of each dovetail a pin -26 vhas been provided extending through openings 28. These pins are embedded in the moulded flange 22- to more securely hold the parts together. Openings 30 in the flange 22 and at the opposite sides of the plate 16receive the rivets which vsecure the friction material 32 to the flange.

A portion of the flange 22 adjacent the openings 30 is depressed as shown at 31 to receive the heads of the rivets 34. s

It will be understood that by such a construction a rigid shoe has been provided which is light in weight and inexpensive to manufacture. While one embodiment of my invention, has been illustrated and described in detail, it will be obvious that various changes including the. size and arrangement of parts may be made without departing from thel spirit of my invention and it is not my intention to limit its scope other than by the terms of the appended claims.

` What I claim is:

1. A'brake' shoe having a generally cylindrical part and a flat radial web provided with lateral pin like projections; said cylindrical part being moulded to the outer edge of said radial flange and embracing said lateral projections'.

2. A brake shoe havin'g a plate onefedge of which is curved to fit the inner periphery of a brake drum, projections on one edge of said plate, pins extending through said projections, and a cylindrical liange .moulded to the edge having the projections and pins, said projections and pins embedded in said flange.
