UNITED Y STATES PATENT FFioE.

SHERBURN SANBORN, OF CHICAGO, ILLINOIS.

RAILWAY-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 544,008, dated August 6, 1895.

Application filed June 3, 1895. Serial No. 551,449. (No model.)

It; all whom it may concern:

Be it known that I, SHERBURN SANBORN, a citizen of the United States, residing at Ohicago, Illinois, have invented certain new and useful Improvements in Railway-Signals, of which the following is a specification.

The object of my invention has more especial reference to the construction of the posts for railway-signals; and my invention consists in the features and details of construction hereinafter described and claimed.

In the drawings, Figurel represents a side elevation of my improved signal-post, and Fig. 2 a transverse section taken in the line 2 of Fig. 1.-

In making my improvemets I make a post A, intended to be of the desired height to support the lights, signal-arms, and other parts forming the complete railway-signal; As to these parts I do not deem it necessary to enter into specific or detailed description, as they may be constructed and operated as usually done. In constructing the signalpost A, however, I take two bars of iron B, provided with heads I) and bases b, connected by webs b and of the desired length to give the requisite height desired in the post. These bars are placed base to base and fastened together by bolts or rivets, as shown in the drawings, for a portion of their length. The bars above, the point where their bases are riveted or fastened together are spread apart so as to afford a space 0 between the bases. This space afiords room for mounting the operative parts of the signal in place between the bases of the bars, which are wide or broad enough to sufficiently house and protect them. The post when thus completed is intended to be securely set or planted in the ground to occupy a vertical position and elevate the signal-lights and other parts to the required height.

By employing bars provided with heads andbases, as shown in Fig. 2, sufficient base is secured to enable the post to be firmly and securely planted in the ground, while the di minished thickness of the web permits earth and gravel to be firmly and securely packed in, about,-and around the post to prevent its ready or easy displacement, and the spreading of the upper portions of the bars apart furnishes less resistance to the action of the wind than where large and solid posts are employed, and at the same time sufficient room is secured for the location, arrangement, and operation of the working parts of the signal.

What I regard as new, and desire to secure by Letters Patent, is-

A post for railway signals, comprising two bars provided with heads and bases connected with Webs, and being attached or fastened together base to base for a portion of their length, and spread apart to afford room for the location and attachment of the operative parts for the remainder of their length, substantially as described.
