BRAKE-SHOE.

` Specification of Letters Patent.

Patented Nov. 2, 1915.

Application led May 4, 1915. Serial No. 25,687.

for reinforcing the wearing body of the shoe, and preventing any of the fragments should vthe shoe become broken' in service, from becoming detached or separated from the shoe.

The invention more particularly relates to that type of shoe which includes wroughtv metal inserts in its wearing face, it being one of the purposes of the invention to reinforce and strengthen that part of the cast bodyof the shoe which is necessarily weakened by the inserts.

A further object is to provide a brake shoe with a steel reinforcing back to which is secured, during the process of manufacture, a cage formed ofv` expanded metal or Wire mesh, and around which the body metal of the shoe is cast. The body metal Hows throughout the interstices of the open-work metal cage and is reinforced thereby, and at the same time, provides a composite-wearing face for the shoe, the same being formed of cast and ductile metals.

A further object is to provide the wearing body of a brake shoe, which includes wrought metal inserts, with av reinforcing cage, embedded therein during the process of manufacture of the shoe, and which cage is formed of ductile open-work metal, reinforcing the body of the shoe throughout its entire length and preventing the separation of any parts of the body of the .shoe from the back, should they become broken in service.

Other objects and advantages will appear as the description proceeds, wherein it 1s t0 be understood that changes 1n' the precise embodiment of the invention, can be made within'the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings, the preferred embodimentlof our invention is disclosed, wherein Figure 1 is a longitudinal vertical section of a brake shoe embodying the characteristic features of our invention; Fig. 2 is a plan view of the wearing face thereof; Fig. Sis a plan view of the shoe back; Fig. 4 is a view in cross-section taken on the line 4-4 of Fig. l; and Fig. 5 is a view in cross-section taken on the line 5-5 of Fig. 1.

'Referring specically to the several views wherein corresponding parts are indicated v ing lug 11 and the longitudinally extending openings` 12, the steel reinforcing back, as thus constituted being of the usual and preferred form. rIhe edges of the steel reinforcing back are turned over so as to define v the side walls 13, and between which is located a reinforcing cage 14, preferably formed of expanded metal or wire' mesh. The reinforcing cage 14 extends the entire lengthfof the steel reinforcing back and is y formed with the bottom wall 15 and sides 16, the latter being contained between and protruding some little distance beyond the extremities of the side walls 13 of the steel rej inforcing back.

' The spaced sides 16 of the reinforcing .cage embrace therebetween the wrought metal inserts 17, around which the vbody 18, of the shoe is cast. The body metal 18 flows up through the openings 12 in the steel reinforcing back and also around the endsy thereof, resulting in the formation ofl the end stops 19 and the secure anchorage of the body to the back. l

The sides of the reinforcing ca e project beyond the ends of the inserts 1g, and reinforce throughout its entire length that portion of the cast body of the shoe which is necessarily weakened by the presence of the inserts. rlhe reinforcing cage will therefore prevent any portion of the body of the shoe from becoming i separated therefrom should parts of the shoe become broken or fractured in service. The wrought metal inserts 17 aree preferably provided with beveled side edges which render more secure their anchorage "within, the ycast metal wearing body of the openwork metal reinforcing cage embedded within said body and including aback and spaced sides. v 2. A brake shoe comprising a cast metal body with inserts embedded therein, and an openwork metal reinforcing cage embedded within said body and including'a back and spaced sides, said sides embracing said inserts therebetween. v

l3. A brake shoe comprising a cast metal body with inserts embedded therein, and an expanded metal reinforcing cage embedded Within said bodypand including a back and spaced sides, said sides embracing said inserts therebetween.

4, A brake shoe comprising a reinforcing back, a cast metal body anchored thereto, an openwor'k metal reinforcing cage embedded within said body, and Wrought metal inserts provided inthe Wearing face of said body.

5. A brake shoe comprising a reinforcing back, a cast metal body carried thereby, a

reinforcing member formed of openwork metal and including a back and sides extending lengthwlse of said back 'and embedded within the cast metal of the body of meaooe the shoe, andinserts provided in the wearing face of saidl body and embraced between the sides of said reinforcing member.

6. A brake shoe comprising a reinforcing back, a cast metal body carried thereby, a

reinforcing member formed of expanded metal and including a back and sides extending lengthwise of 'said back and embedded within the cast metal of the body of cluded between the sides of said reinforcingcage.
