Description

UNITED `STATE-sf PATENT orrion.
.. IFRANK P. COLLIER, o F WILMETTE, ILLINOIS.v
l BRAKE-SHOE..
t Specification of Letters Patent.
Patented Dec. 5, 1905.
\ Application filed mmh 13, isos. serial No. 249,732.
l To .all whom it may concern,.-
Be it known that I, FRANK I. COLLIER, a citizen of the United States, residing at Wilmette, inthe'county of Cook and .Stateof Illinois, have invented new and useful Improvements in Brake-Shoes, of which the following is a specification.
The object of this invention isto reinforce and strengthen a brake-shoe in a simple and inexpensive. manner, to avoid fracture in handling and in service, and to prolong the life of the shoe. p I have shown one embodiment of the invention in the accompanying drawings, in which-'- 'cut out at 8 on its side edges to permit the body metal to flow up` andl form the attachinglug 9. The end lugs 10 and the guide-lugs'll are also formed by the body metal which viiows` v .'up around the sides and ends of the plate.
The plate is locatedbeneath the attaching-lug and the end and guidelugs and is exposed on the back of the body of the shoe between said lugslI -have shown the invention embodied in a' solid cast-iron shoe of a common type; but it will be understood that it can be usedas well in connection with composite shoes and in shoes ofthe many dierent types common in the art.
The .plate reinforces and strengthens the shoe against fracture in handling and in service, and it can be embodied in a shoe at very little additional cost.
It enables the shoe to Y remain in service until the body or wearing part has practically been worn away entirely,
and thereby greatly prolongs the life of the shoe and secures the maximum degree of serv- Yice therefrom.
n Without limiting myself to the exact construction and arrangementy of parts herein shown and described, what I claim, and desire vto secureby Letters Patent, is-
A brake shoe comprising an imperforate back plate' bent to conform to the curvature of the shoe and having uniform curvilinearsurfaces, and a body cast on said plate and. having at each fend integral end and guide lugs, said'plate being of less length and width than the body and located beneath said lugs and exposed therebetween andhaving its edges beveled -to make body.
