To all whom it may concern:
Be it known that JAMES S. THOMPSON,
a citizen of the United States,` residing at Pelham, in the county of lWestchester and State of N ew York, have invented certain new and useful improvements in Brake Shoes, of which the following is a specification.
This invention refers to improvements in brake shoes of the insert type and its object is to provide a strong and substantial shoe reinforced and strengthened against fracture and having a composite wearing face to prolong the life of the shoeV and at the same time provide high braking eciency.
In the accompanying drawings illustrating the invention- Fig. l is a side elevation partly in section of a simple form of car shoe illustrating one embodiment of the invention.
Fig. 2 is a transverse` sectional viewon line 2-2 of Fig. l. v
Fig. 3 is a side elevation partly in section of a flanged shoe embodyingthe invention in another form.
Fig. l is a transverse sectional view on line 4 4 of Fig. 8.
Referringl to the drawings, the bodyv 5 is preferably provided with a suitable reinforcing` and strengthening ductile metal back 6' which may be made in any of the many different ways well known in the art. A plurality of reticulated metal strips 7 are ar-' ranged one above the other parallel to the wearingface of the shoe and spaced apart, as shown in Figs. l and 2, or superimposed one upon the other, as shown in Figs. 3 and 4. These strips may be arranged with their openings registering or they may be arranged in staggered relation as desired. The strips are curved on an arc corresponding substantially with thecurvature of the wearing' face of the shoe and they may extend partway or all the way from the wearing' face to the reinforcing back.
Insert sections or blocks 8 of any desired metal are cast on the strips transversely thereof in suitable shapes and at such intervals as may be required, so that the sections or blocks will be rigidly interlocked with ythe strips and the strips will -be held in proper position by the sections or blocks. The interlocked sections or blocks and strips forman insert which is placed in a mold with the' reinforcing back, and the body metal is then cast thereon to form a shoe of composite character in which all the parts are interlocked.y Theinsert reinforces and strengthens the body and forms a strong and substantial shoe.r The wearing face of the shoe is composed of the body metal, the strip metal and the insert 'or block metal, and these metals'are distributed throughout the wearing face in a manner which will produce an etlicient braking friction and at the same time prolong the life of the shoe.
may use strips made of expanded metal, wire mesh or any other binding, bonding or reinforcing reticulatedY metal, and sections or blocks of any ductile or other metal suitable for the purpose,a nd I may embody the invention in car or locomotive shoes of any kind with or without reinforcing backs.`
I claim: i Y
l. A brake shoe comprising a body, and a composite'insert embedded in the body and comprising a plurality of reticulated metal strips arranged one above the other inclose JAMES S. THOMPSON.
