' BRAKE-ROD JAw.

Specification of Letters Patent. P t t d b, 7,1922,

Application filed February 20, 1919. Serial No. a7s,is4.

To all whom it may concern: Be it known that I, HAYS, a resident of Hammond, in the county of Lake and State of Indiana, have invented a new and useful Improvement in Brake- RodJaws, of which the following is a specification.

The invention described herein has for its object the provision of a brake rod j aw of simple and cheap construction and which can be easily assembled with the brake rod. The invention comprises a brake rod jaw consisting of two parallel members connected at one end by a web which is adapted to be engaged by a hook on the endof the brake rod, and provided with lugs extending laterally from the web and'adapted to engage the body of the rod and prong of the hook to lock the latter in engagement with the jaw. The invention is hereinafter more fully described and claimed. 7

In the accompanying drawing Fig. 1 is a plan view of my improved brake rod aw, showing a portion of the brake rod in engagement therewith; Fig. 2 is a side elevation of the same; Figs. 3 and 4 are sectional i :underside of the web. After the parts have views on. planes indicated respectively by the lines 33 and irl, Fig. 2; Fig. 5 is a plan view of a form of blank adapted, by bonding certain of the parts, to form the aw; and 6 is asectional view on a plane indicated by the line 6-6, Fig. 5.

While my improved jaw can be formed by any suitable means, as by casting or,

forging, providing malleable metal is used in forming the cast1-ng,-it is preferred to first form a blank from wrought metal by means of suitable dies by what is known'as the blanking out method, the dies being so shaped as to form a body of suitable shape by causing the metal to flow to the different parts of the matrices of the dies which are so formed that the excess of metal is distributed to those parts of the jaws subjected to the greatest strains in the use of the ELMER M. SUMMER- ception, as hereinafter described, of the body 6 of the rod and of the prong 7. of the hook.

The web on its opposite sides at its ,outer end is provided with lugs or wings 8 and 9, said wings lying in different planes and extending from diagonally opposite edges 7 of the extension of the web. After the blank has been stamped out and shaped as described, the parts or members 1 and 2 are,

"by any suitable means, bent to bring the planes of their faces into parallelism and the centers of the eyes 3 into alignment, the lines of bend corresponding to and being coincident with the lines of junction of the web withthe portions 1 and 2. It is preferred, that this bending operation should be effected in suitable dies as is well known in the art.

' In connecting the jaws to the rod, the end.

been assembled as described, the lugs 8 and 9 are bent in opposite directions, one around the body 6 of the rod and the other around the prong of the hook '7, thereby firmly clamping both portions ofthe rod in the seats in the webs, and preventing-the hook from opening and becoming disengagedendwise of the web. 1

' It is preferred that the web portion 4 be made comparatively long in order that the rod and prong of the hook may have long bearing surfaces on the web, and have the eyes of the jaws in or approximately in alignment with the line of draft, thus avoiding transverse strains.

I claim:

-1. A brake rod jaw comprising parallel jaw members, a web connecting one end of said members and serving as means for engaging a hook on a brake rod, said web extending rearward beyond the jaw members and having channels in the opposite sides thereof adapted to receive the prong and body of a brake rod hook, and lateral wings on said extension adapted to be bent around the prong and body of the brake rod hook to clamp them in the said channelled seats.

2. Al brake rod jaw comprising parallel jaw members connected by aweb, said web extending rearward from the jaw members and'having its opposite sides channeled to form seats for theprong and body of a1 brake rod hook, and lateral wings on said extension adapted to be bent around the prong and body of the brake rod hook. to

clamp them in the said channels.

of said jaw members and extending rearwardly therefrom in a plane perpendicular to the'planes of the jaw members, the rearwardly extending portion havin curved channels in its opposite sides adapted to' receive the prong and body; of a brake rod jaw.

the base of said jaw members, said web lying in a plane perpendicular to the plane of the jaw members and extending rearwardly from the base of said members, seats formed in the opposite sides of the said rearward extension and adapted to receive the prong and body of a brake rod-hook, v

and wings extending in opposite directions prising a forged blank having parallel-j aw members extending from a connecting web portion, said connecting portion extendlng rearwardly beyond. the bases of the jaw members and having its opposite sides foirnied'into receiving channels,-and lateral wings extending from the sides-of the said rearwardly extending web portion beyond the bases of the jaw portions, the said forging being adapted to have the jaw members 7 bent into parallel positions and the wing 4. A brake rod jaw comprising parallel jaw members,a transverse web connecting portion bent around theprong andbody portion of the brake rod hook seated in the v said channels.

In testimony whereof, I have hereunto
