THOMAS A. GRIFFIN, OF CHICAGO, ILLINOIS.

RAiL-BRACE.

SPECIFICATION forming part of Letters Patent No. 393,152, dated November 20, 1888.

(N0 model.)

To aZZ whom it may concern:

Be it known that I, THOMAS A. GRIFFIN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Irnprovements in Rail-Braces, of which the following is a specification.

lhe rail-brace shown and described herein is an improvement on the class of rail-braces shown in the patent granted to me March 30, 1886, and numbered 338,953,in which the brace is formed by forming a short rail-section so that the foot of the rail-seetion shall fit against the track-rail and the head of the rail-section be fastened to the tie.

In practice it has been found that it is desirable to use the kind of brace shown in Fig. 6 of said patent, (the same being formed by flattening the head of the rail-section by side blows, as in said patent set forth,) for the reasons that less forging is required,and the metal is therefore less violently worked, the brace is less liable to flaws, and it is more cheaply made.

The object of my invention is to combine the advantages of both forms shown in said patent by so modifying the shape just referred to that it shall more directly and firmly support the head of the track-rail and shall permit the use at the foot of the track-rail of one or more spikes beneath the rail-brace.

The accompanying drawings show a rail-- brace constructed in accordance with my improvement, Figure 1 being a perspective and Fig. 2 an end view of ashort portion of trackrail with the brace in position.

A is the track-rail; B, the brace. As will be seen the upwardly-curved part 0 of the brace rising from the tie (the web portion of the rail- 1 directly toward the under side of the railhead, and the lower edge of the head of the brace 11 extends only to the junction of the flange and web of the track-rail instead of extending along the flange, as before, thereby permitting the use of one or more spikes, D. beneath the brace. The extra metal in the upper edge, I), of the brace-head is rendered available by raising the web portion 0,.it being driven back and upset by the dies in the proeessofshaping the brace-head,and it greatly portion 0, and thus, together with the more advantageous position of the part 0, prevents entirely the possibility of bending the brace by the forces tending to tilt the track-rail.

I claim- 4 l. A brace constructed from a blank of the form in cross'section of a T-rail, the head of the blank forming the foot of the brace and the foot of the blank forming the head of the brace, the lower edge of the brace-head extending only to the junction of the web and flange of the track-rail, substantially'as described and shown.

2. A brace constructed from a blank of the form in cross section of a T-rail, the head of the blank forming the foot of the brace and the foot of the blank forming the head of the brace, the upper part of the brace-head being re-enforced by upsetting the portion of the foot of the rail-section from which it is formed, substantially as described.
