:BRAKE SHOE.
Patented Jan. 3, 1922.
Application filed December 17, 1919. SeralANo. 345,533.
To @ZZ whom. t may concern.'
Be it known that I, JAMES S. THOMPSON, a citizen of the United States, residing at Pelham, in the county of lVestchester and State of New York, have invented certain new and useful Improvements in Brake Shoes, of which the following is a specilication. Y
This invention relates to improvements 1n brake shoes and more particularly to that type in which the body metal is cast upon plurality of strips, or a bundle, of'eX- panded metal, or wire mesh', or other binding, bonding, or reinforcing reticulated metal arranged on edge to the wearing face of the shoe and more broadly set forth in my companion application, Serial No. 345,532, filed concurrently herewith.
yhe objectief the invention is to provide for the assembly of inserts with the reticulated metal strips and in a simple and effective manner to properly position these parts with respect to each other for embedment in the cast body of the shoe.
In the accompanying drawings- Fig. 1 is a side elevation, partly in ysec.
tion, illustrating one form of-my present invention.
Fig. 2 is a cross sectional view on the line 2-2 of Fig. 1.
Fig. 3 is a view similar to Fig. 1, showing another form of the invention.
Fig. L1- is a cross sectional view on the line ssof Fig. 3. v
Fig. 5 is a view similar to Figs. 1 and 3, showing another form of the invention.
Fig. 6 is a cross sectional view on the line 6 6 of Fig. 5.
Referring to the drawings, the body 7 is preferably provided with a suitable reinforcing` and strengthening ductile metal back S which may be made in any of the variety of different ways well known in the art.
A plurality of reticulated metal strips are arranged on edge to the wearing face of the shoe and spaced apart between the sides of the shoe. These strips 9 may consist of commercial expanded metal, or wire mesh, or other suitable reinforcing reticulated metal may be used as set forth in my application above referred to. The strips are arranged in the shoe with their openings in registration and insert sections or blocks 10 are arranged in alternate openings of the strips as shown in Fig. 1 or in Fig. 3, or they may be arranged in all of the openings as shown in Fig. 5. The strips are also preferably inclined on edge to the wearing face ofthe shoe, as clearly shown in the cross section views, and this is particularly advantageous in the assembly of inserts with .expanded metal strips, because the openings of the strips will register better when the strips are thusinclined and permit the inserts to be inserted more readily into the openings. If the strips are arranged in an upright position perpendicular to the wearing` face ofthe shoe, as they may be, it will be a little more diiiicult to insert the insert sections or blocks, but this can be done and very satisfactory results achieved by this arrangement. However, I prefer the inclined or tilted arrangement because it not only facilitates the assembling of the insert sec-tions or blocks, but the position of the exposed parts of the strips on the wearing face of the shoe changes as the shoe wears vdown and thereby avoids any chance there may be of thestrips scoring or cutting the wheel.
My invention provides for 'assembling these strips and the insert sections or blocks easily and quickly into proper relation to form a single insert which is placed in the mold with the reinforcing back to have the body metal cast thereon. The engagement of the insert sections or blocks with the strips will hold the strips in proper spaced relation and in properl position, whether it be inclined or upright, and when the body is cast thereon, the several parts will be interlocked and interengaged in a secure and rio'id manner so that if the shoe should be fractured, the parts thereof will be held together so that the shoe may continue in service and without falling apart. The strips may be spot welded or otherwise suitably secured to the reinforcing back if found desirable. It depends upon the size and shapes of the insert sections or blocks and the mesh of the strips whether the inserts can be arranged in the strips as shown in. Figs. 3 and 5 or whether some distortion of the strips will'be necessary to accommodate the inserts as shown in Fig. 1, and this is true whether expanded metal strips as shown in the drawings are used 0r wire mesh, or other reticulated metal strips are used.
The insert sections or blocks may he made ofany desired metal or material and in any shape adapted Jfor the purpose. `When they are arranged in alternate openings of the strips as shown in Figs. 1 and 3 their outer faces Will lie substantially in a plane parallel with the Wearing face of the shoe; but
when they are arranged in all of the open` struction, but I reserve the right to make all such changes in the form, construction and arrangement of parts as fairly fall Within the scope of the appended claims.
I claim:
l. A brake shoe comprising a plurality of reticulated metal strips arranged on edge I to the Wearing face of the shoe and having registering openings, insert sections or blocks arranged in said openings transversely of the strips, and a body cast on th strips and insert sections or blocks.
2. A brakeshoe comprising a plurality of expanded metal strips arranged on edge to the Wearing face of the shoe and having registering openings, insert sections or blocks arranged in said open-ings transversely of the strips, and a body cast on the strips'and insert sections or blocksfj 3. A brake shoe comprising a plurality of reticulated metal strips arranged in an inclined position on edge to the Wearing face of the shoe and having registering openings, insert sections or blocks arranged in said openings, and a body cast on the strips and insert sections or blocks.
4f. A brake shoe comprising a plurality of expanded metal strips arranged in an in clined position lon edge to the Wearing 'face of the shoe and having registering openings, insert sections or blocks arranged in said openings, and a body cast on the strips and insert sections and blocks.`
5. A brake shoe comprising a plurality of reticulated strips spaced apart on edge to the Wearing face of the shoe and having registering openings, insert sections or blocks arranged in said openings trans- Versely of the strips and in staggered relation, and a body cast on the strips and insert sections or blocks.
6. A brake shoe comprising a reinforcing back and a plurality of reticulated metal strips secured to said back in an inclined position on edge to the Wearing face of the shoe and having registering openings, insert sections or blocks arranged in said openings, and a body cast on said back,
strips and insert sections or blocks.
