Specification of Letters Patent. a Patented J 11163; 1918';

Application filed February 13, 1912. Serial No. 678,452;-

To all whom it may concern:

Be it known that. I, JUDsoN Coon, a citizen of the United States of America, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in ReinforcedBrake-Shoes, of which the following is a specification.

This invention relates to brake shoes and, more particularly, "to that class of shoe formed with metal insertsembedded Within the cast-metal body portion of the shoe and worn away therewith.

The object of my invention is to provide inserts of such a form that they will impart a maximum of strength to the slice; will tend to bind the shoe togethe$and hold it intact should the cast body portion become cracked and also .so formed that the inserts will not loosen and drop out through cracking or splitting of the body.

lVith theseand such other objects in view as will hereinafter more fully appear, my invention consists in the novel construction and arrangement of parts described in the annexed specification and shown in the accompanying drawings, in which Figure 1 is a sideelevation of the shoe.- Fig. 2 is a sectional view taken on the line 22 of Fig. 1. Fig. 3 is a perspective View, shown in broken detail, of the insert.

In said drawings a brake shoe 4: formed with a suitable securing lug 5 has embedded therein the inserts 6 of any. suitable ma terial but, preferably, of expanded metal. These inserts are, as shown, bent in the form of an open T and arranged, the two outer ones occupying the same relative positions at either tra'l one lying in such a way that the cross arms of the T overlap. By this arrangement the back'ofthe shoe is firmly braced and rendered less liable to crack or break under strain and,

side of the shoe and the con;

i by the overlapping of the cross arms, the i liability of complete separation of the parts,

should a crack in the cast-body occur, isf

materially lessened.

The shoe is made in the usual way. The

inserts being set up in the molds the heated '50 metal is poured therein and allowed "to cool. Having described my invention, what I claim as new and desire to secure by Letters Patent, is i l. A brake shoe comprising a body porti'on, inserts embedded therein said inserts being in the form of an open T and having.

their cross arms overlapping.

2. A brake-shoe comprising a cast metal body portion, inserts embedded therein comprlsing strips of expanded metal'bent to form an open T said inserts being arranged with the cross arms of the T adjacent the back of the shoe in such a way that the ones nearer the sides of the shoe have ,5 their cross arms overlappmg the central one to secure the same to the brake head.

In testimony whereof. I hereunto afliX-my signature 1n presence of two witnesses.
