COMPOSITION BRAKE-SHOE. l

Application led May 4, 1915. Serial No. 25,685.

To all whom t may concern:

Be it known that we, JOSEPH D. GAL- LAGHER, a citizen of the United States, and a residentof Glen Ridge, `'countyof Essex, and State of New Jersey, and HAnRY JONES, a 'citizen of the United States, and a resident of Suffern, in the county of Rockland and State of New York, have made and invented certain new and useful Improvements in Composition Brake-Shoes, of which the following is a specification.

This invention relates to composition brake shoes and has for its object to provide a shoe of this type which will be characterized by its long serviceable life and good frictional qualities, as heretofore, one of the objections tothe use of composition shoes has been the relatively short serviceable life thereof and its excessively high frictional qualities.

A further object is to attain the aforementioned ends, that is, to lengthen the life of the shoe and reduce the frictional qualities thereof, in such manner that the various parts which go to make up the completed shoe are securely anchored together and reinforced throughout, so that should any of the parts become cracked or broken in service, they will not fall apart nor become separated from the back of the shoe.4

Other ob]ects and advantages will. appear as the description proceeds, wherein it isto be understood that changes in the precise embodiment of the invention can be made within the scope of what isclaimed without departing from .the spirit of the invention.

The preferred embodiment of our invention is disclosed in the accompanying drawings, wherein Figure. 1 is a view in perspective of our novel and improved brake shoe with portions of the composition body removed; Fig.v

2 is a top plan view of the foregoing; and

Fig. 3 is a view in section .taken on the line 3 3 of Fig. 2.

' The brake shoe, disclosed in the several views, comprehends a reinforcing back 5, which is provided with the integral and outstanding lug 6, whereby the shoe may be securedto a brake head or rigging inthe usual and preferred manner. The back 5 is provided with the overturned side edges and has the openings 8 extending length-l wise thereof and located uponopposite sides of the longitudinal center.

Temporarily anchored to the back, during the process of formation of the brake shoe, 1s the expanded metal or wire mesh cage 9,

Patented Nov. 2, 1915. y

vwhich is formed with the sides 10 and back sections are securely anchored to the back by means of the end stops 13, which are formed by the cast metal flowing up, around, and embedding the ends of the back therein. The cast m'etal end sections 12 are extremely hard throughout and impart the requisite lasting or wearing properties to the shoe.

The wire mesh orexpanded metal cage 9, in connection with the solid end' sections 12, forma container for the reception and anchorage of the composition body 14. The wire mesh or expanded metal extends throughout the entire length of the hard metal end sections and reinforces the same, so that should portions thereof become broken or fractured in service, such parts will not become separated from the back of the shoe.

The hard metal end sections, as illustrated in g. 1, are provided with the confronting depressions or recesses 15, which, in connection with the undercut or beveled end walls 16, serve'to securely anchor and retain the composition body 14 in position. rlhe composition body 14 is forced into the interstices of the expanded metal or wire mesh of the cage and into the confronting recesses 15 of the hard metal end sections, and, as illustrated in Fig. 3, up through the openings 8 in the shoe back, so as to terminate Hush with the upper surface thereof. ln this manner, the composition body is rigidly anchoredto the reinforcing back of the shoe and to the hard metal end sections by the expanded metal or wire mesh, which latter, extending through the composition body, reinforces and binds the same together.

The composition body 14 is formed of any suitable substance or mixture of ingredients which possess the proper frictional qualities. One of the objections heretofore raised kto against the use of composition shoes, was the relatively short useful life thereof, and excessively high frictional qualities. In the present shoe, a long and servlceable life has een provided for and the frictionaLqualities have been decreased, the same being accomplished by reason of the hard metal end sections which lend the requisite wearing or lasting qualities to the shoe and necessarily prevent too great apressure between the compositionbodv 14 and the car wheel, so that only the proper and moderate amount of friction results;

What we claim is l 1. A brake shoe comprising in part a container having a back, and depending sides of open metalwork, and continuous metal ends, said container ada ted to receive and contain a portion of the ody of the shoe.

2. A brakeshoe comprising in part a container having a back, and depending sides of expanded metal, and continuous metal ends, said container adapted to receive and contain a portion of the body of the shoe.

3. A brake shoe comprising in part a container having a back andl depending sides of open metalwork, and continuous or solid metal ends, said container adapted to receive and contain a composition body.

4. A brake shoe comprising in part a container having a back and depending sides of expanded metal, and continuous or solid metal ends, said container adapted to receive and contain a composition body.

' 5. A brake shoe constructed with a container having a back and depending sides, and solid metal ends provided ywith depressions, said container and depressions adapted to receive and contain a composition body.

6. A brake shoe constructed in part of a container having depending sides of open metalwork, and with solid hard metal ends provided with depressions, said container and depressions adapted to receive andvhold a composition body.

7. A brake shoe formed with acontainer having a back and depending sides, and solid metal ends, said ends provided with confronting depressions for the reception and retention of a composition body.

8. A brake shoe comprising hard metal end sections, and a cage of open metalworllt aisance extendin therebetween, and a composition body anc ored thereto.

9. A brake shoe comprising a cage with a back and depending sides formed of open metalwork, hard .metal end sections anchored to said cage, and a composition body disposed between said hard metal ends and anchored to said cage. 1

10. A brake shoe comprising a reinforcing back, a cage of open metal work extending lengthwise thereof, hard metal end sections anchored to said reinforcing back and to said cage, and a composition bodyextendin between said hard metal ends and anchore to said cage and reinforcing back.

11. A brakeshoe including spaced hard metal end sections, a cage of open metalwork embedded therein and extending therebetween, said end sections provided with confronting recesses, and a body possessing high frictional qualities anchored to said cage and extending within saiddepressions.

12. A brake shoe including spaced hard metal end sections, a cage of expanded metal embedded therein and extending therebetween, said end sections provided with confronting recesses, and a body possessing high frictional qualities anchored to said cage and extending within said depressions.

13. A brake shoe ycomprising a reinforcing back, a cage including a back and side walls of openwork metal and extending lengthwise of said brake shoe back, hard metal end sections anchored to said back embedding said caOe therein and reinforced thereby, said end sections and cage forming a container, and a composition body carried by said container and extending vbetween said hardmetalend sections.
