INVENTOR .S.H.CAMPBELL IIIIIIIIH 1i Original application filedbctober 15 'To all w ham it may concern:

Be it= known that I, STERLING H. CAMP- BELL, ica, residing at the city of St. Louis, State of Missouri, United States :of America, have invented certain new and useful Brake-Rod Jaws, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,

7 forming part of this specification.

My invention relates to a brake rod aw and more particularly to a forged metal brake rod jaw of the nonwelding type.

One object of my invention is the production of a suitable forged metal blank from which the brake rod jaw may be formed by boring or punching pin eyes and rod eyes 1n the blank. Another object of my invention is to so form a blank that one size and shape of blank may be utilized to produce brake rod jaws for varying sizes of brake rods.

In the accompanying drawings which illustrate two forms of brake rod jaws made in accordance with my invention, Figure 1 is a side view of the blank for producing my preferred form of brake rod jaw, Fig. 2 is an edge view of the same, Fig. 3 is a longitudinal section of the completed jaw, the brake rod being shown in position. Fig. 4; is an end view of the part shown in Fig. 8. Fig. 5 is a plan view of a blank for producing a modified form of jaw. Fig. 6 is a section taken on the line 6-6 of Fig. 5, Fig. 7 is a side view of the completed jaw formed from the blanks shown in Figs. 5 and 6, the brake rod being shownin position, and Fig. 8 is an edge view of the jaw shown in Fig. 7, the brake rod being omitted.

Referring first to Figs. 1 to 1 inclusive, 10 indicates a rod base which has formed integral with it a pair of arms 11 each terminating in an enlarged end 12 preferably circular in shape. formed integral therewith is a rod seat 13. All the parts of the blank taper from a central dividing line 14, so that the forming die may have the necessary draw, and come quently the central parts of the enlarged ends 12 project beyond the sides of the arms 11 as indicated at 15 in Fig. 2. This surplus metal, however, is removed when the pin eyes 16 are formed in the ends 11 by punching or boring, as indicated by the dotted lines in Fig. 4. 17 are rod eyes which are a citizen of the'United'States of Amer- Situated between the arms 11 andism-serial Ne. so,e44.

The rod base 10 is made of such size and shape that various sized rod eyes 17 may be formed therein to coooperate with the same rod seat 13 so that one form. and sizeof blank may be used to produce rod jaw sfor rods of varying sizes. The part 20-of the rod base lying between the two rod eyes 17 forms a rod bending support at one side of recesses 21 into whicha portion of therod 18 is adapted to be bent, the rod seat 13 forming a rod bending support at the other side of said recesses. By striking the rod 18 at the point 22 with a suitable tool, the rod is bent to the recess 21 thus efilectively preventmg its retrograde movement relative to the In Figs. 5 to 8, I have shown a modified form of brake rod jaw which is formed from a blank forged out of flat sheet metal as shown in Fig. 5. In this form of aw the pin eyes 16 and rod eyes 17 are formed during the operation of forging the blank and at the same time openings 23 are formed in the blank to receive a bolt or rivet to form I Specification of Letters Patentd se t "27- a rod seat 2 1 in lieu of the integral rod seat .85

13 of the form of jaw hereinbefore described. In this formof jaw the open space 25 between the part 20 of the rod base and the. rod seat 2a forms the recess into which a portion of the rod is adapted to be bent by striking it at the point 22, to prevent its retrograde movement relative to the jaw.

This application is a division of application'Serial No. 330,94A, filed Oct. 15, 1919.

Having fully described my invention, whatI claim as new and desire to secureby Letters Patent of the United States is:

1. A forged metal blank for forming brake rod jaws, comprising a pair of arms terminating in enlarged ends for the pin eyes, said ends having their central parts extendingbeyond the sides of thearms, said a pair of arms integral with said base, all
