ZEPHAXIAH E. WILLIAMSON,

or single cars on a milroa To all whom it may concern..-

Be it known that I, ZEPHANIAH E. WIL- LIAMSON, a citizen of the United States, residin at Sheffield, in the county of Bureau and tate of Illinois, have invented a new and useful Improvement in Railway-Signals, of which the following is a specification.

This invention relates to improvements in means for announcing the a proach of trains track, at crossings, stations or other points desirable and particularly to that class in which audible signals are given by a gong or hell, and the objects are: to provide mechanical means that will cause a bell to ring repeatedly as each wheel passes a point, or points, in its approach to the bell location, and also, to'

provide such means in terms not easily disarranged, which are not subject to climatic or storm conditions, or affected by frost or rust and which are simple in arrangement and inexpensive in ap lication. These objects are attained by t 1e novel combination and arrangement of parts hereinafter-fully described and shown in the accompanying drawings,forming part of these specifications, and in which:

Figure 1, is a sideelevation of a railroad track having the invention a plied. Fig. 2, is a plan view of the same. ig. 3, is an enlarged side elevation of the operative mechanism and, Fig. 4, is an end view of the same shown in position.

The invention consists of an elliptical spring comprised of two independent leaves 1 and 2, hinged together at their ends 3, in such manner that when the leaves are forced towards each other, as by pressure applied to the up er leaf, the ends may move freely outward, lint return to the normal osition when the ressure is. removed- The ower leaf 2, is firmly secured at the middle of its length and lowest point bya clamp 4, or equivalent means bolted to a cross tie or sleeper used in su porting the rails and, close to the inner side ofthe outer rail on which the cars may approach. The upper leaf 1, is provided at its center and highest point, which is arranged approximately level with the head of the rail, with a depending lug or projection 5, to which is attached the end of a flexible connection, as a chain 5, the same running over a ulley 7, pivotally secured on a bracket 8, w iich may be part of the clamp 4, or separate from it as is preferred. The chain continues under a similar pulley 9, on the x Specification of Letters 1? tent. Application filed November 30, 1907. driialflo. 404,491.

RAILWAY-SIGNAL.

Patented Aug. 4, 1908.

I .v'\\ bracket 1Q; and passes over a series pulleys 11; around the pulley 12, under and eyond thetrack-rail to the pulley 13, at the "a i l f guide 7 footof the ost 14; here it may enter, if the post be hol ow, or follow up the side, if the post he solid,\5connect with the spirally. wound spring 1 attached to the post and carrying the bell 16, in such manner that the bell is caused to ring whenever the chain or other connecting means he pulled. This is accomplished each "time the s ring leaf 1, is

depressed,- which is done by t 1e pressure of V V car-wheel flanges contactin with the leaf in I its passa e over it. AsuitadJle covering may be provided to guard and protect the connections, the same being disposed on or beside the track, to prevent possible injury thereto.

Obviously the arrangement of the bell support is such that the bell will ring several times when the spring support is put in motion and that such motion will be transmitted to it by the contact of every wheel passing over the elliptical spring at the side of the rail; a car approaching either head on or backing will produce the same results.

The simplicity of the device will be apparent as well as the entire absence of any minor springs or parts liable to rust and hence fail to operate at possible critical moments.

ho changes are made in the application of the device to the rails or road-bed and no disfigurement to the road-way is caused thereby.

As many of the elliptical springs may be used as desired,'preferably at distances of five, three and two hundred feet from the signal 0st and all connected to the same bell, which is located usually at crossin 's where watchmen are not regularly statione or the same may be used in connection with watchmen as cautionary si nals.

Such. modifications maybe made as in the use of .a combination of chains and rods in the connections and also in the location of the same, whether upon the ties direct or upon posts beside the track, without depart.- ing from the scope of the claim.

Having thus described my invent-ion, what I claim as new and desire to secure by Letters Patent of the United States, is

In a railway signal, the combination of a rail, a tie supporting the same, a rail clamp securing the rail t the tie, an elliptlcal spring mounted on said clamp, said spring comprisnect-e at the ad'acent opposite ends thereof,
