ANTHONY Gr. OLBERDING, OF CINCINNATI, OHIO, ASSIGNOR TO THE COLUMBIA FOUNDRY COMPANY, OF CINCINNATI, OHIO, A COR-PO- RATION or o rno.-
BRAKE-SHOE.
Specification of Letters Patent.
Patented Nov. 6, 1906.
To all whom it may concern:
Be it known that I, ANTHONY G. OLBER- nING a citizen of the United States of Amera, and a resident of Cincinnati, county of Hamilton, State of Ohio, have invented cer tain new and useful Im rovements in Brake= ghoes, of which the fo lowing is a specifica- 1011. My invention relates tobrake-shoes having a cast-metal body and a steel back.
The object of In invention is a brake-shoe 7 having a steel bac ,which afiords a grippingsurface to the cast metal, such that thejoint between the two metals is proof against both tensile and lateral strains and which is provided with a strong and economical means of securing it to the brake-head. This object is attalned bv the means described in the specification and illustrated. in the drawings, in whichv Figure 1 is a top plan view of a brake-shoe embodying my invention. Fig. 2 is a detail side elevation of the back. tudinal sectional elevation upon line 2 a, Fig. 1. Fig. 4 is a plan View of the flanged brakeshoe embod ing my invention. Fig. 5 'is a detail side e evation of the back used in the form of shoe illustrated in Fig. 4. Fig. 6 is a side elevation of the shoe illustrated in Fig. 4. Fig. 7 is a sectional view upon line 'w w of Fig. 6. Fig. 8 is a sectional view on line 12 '1) of Fig. 4.
with it a series of diagonal U-shaped stra s a, which are formed by making a series of diagonal'parallel slits-in the back and by swaging the strap so formed downward into a U -shape.
In the center of the back shown in 1 a couple of transverse slits are formed and a transverse U-shaped strap a is struck upward from the back to form a lug for attac ing the brake-shoe to the brake-head. After the back has been so formed it is inserted in the top of a'mold, and the cast metal to form' the body B is allowed to flow into the mold nd around the straps a-to the level of the Fig. 3 is'a longiback, but not to cover the outer surface thereof. The perforations in the back formed by the straps coming at close inter vals afford a most ellicient means for the escape of the gases which are caused when a holes being formed at the joint between the cast metal and the steel.
The cast metal flowing over the U-shaped strap forms a most secure means of holding the two together. The advantage of making the straps diagonal is this: In rolling steel it is generally rolled lengthwise, and it is found that a diagonal strap affords much greater resistance to strains than a transverse or a longitudinal strap, since it crosses the grain which seems to be formed in the steel in the process of rolling. Each strap being diagonal forms a much greater resistance to a transverse strain than would simply a transstrain is distributed is greater in the diagonal strap than in a transverse.
Lug a, being formed integral with the heated metal strikes a cold, and thus prevent verse strap, since the distance over which a back A, is strong and is economically pro-.-
duced.
In the forms illustrated in Figs. 47 the I shoe has a flange, and the dia onal straps a? are formed in the flange A of t e back 'as well as in the tread A. In this form of shoe the usual hole a, is left in the back and through the body of the shoe to receive the bolt for Referring to the parts, back A has pro- "jecting down from it and formed integral attaching to the head. At the opposite end of the back from the hole a a lug 1s left projecting, which is turned over into a hook a or crimped. This crimping reinforces the hook and renders it strong and durable.
What I claim is 1. A brake-shoe consisting of a steel back having a series of diagonal U-shaped straps struck down therefrom and a castmetal body joined to the back by the metal passing over andaround the straps.
2. A brake-shoe consisting of a steel back having a series of diagonal U-sha ed stra s struck downward from the trea and t e the edges a of this hook (I, being turned over 2 esmes flange thereof, and asset-metal body secured its edges, a east-metal "body and means of to the 212101: ba the metal passing over and securing the hack and the body together. surroun in testm s. v 1 x 3.
