PATENT OEEICE.

SOUTH CHICAGO, ILLINOIS.

RAILWAY-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 335,243, dated February 2. 1886.

(No model.)

To all whom it may concern:

Be it known that I, NATHAN M. REYNOLDS, of South Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Railway-Signals, ofwhich the following is a full, clear, and exact description, that will enable others to make and use the same, reference being had to the accompanying drawings, forming a part olthis specification.

This invention relates to improvements in automatic alarm-signals for railway-crossings; and it consists of certain novel features in the construction, arrangement, and operation of parts, as will be hereinafter set forth in detail.

Figure l is a view in perspective showing the arrangement of the device with relation to a railway-track; Fig. 2, an enlarged detached detail. Fig. 3 shows the signal-gong, together with the clappers and operating-wires. Fig. et shows the arrangement of the device on each side of the crossing, and Fig. 5 is a modification.

Referring to the drawings, A represents a post placed at any convenient point alongside of the track A and at any required distance from the crossing or station. The outer end of the rock-shaft B is provided with a suitable journal-bearing in the lower end of the post A, and extends horizontally therefrom to a point adjacent to the track, and rests in the journal-box a. Mounted on the outer end of this rock-shaft, and rigidly secured thereto, is thelever-arm B, extending laterally from each side of the same', as shown in Fig. 1. The opposite end of this rockshaft is provided with the rocker-arm C, extending from each side of the shaft, the ends of the arm being bent upward, so as to bring the same on about a level with the track and present a proper contacting-surface for the moving car-wheels.

On one side of the post A, and near the top, are pivoted the cross-arms aa',running at right angles with reference to each other, as shown in Figs. 1 and 4. To the ends of the horizontal arm c are attached the upper ends of the wires ca, the lower ends of which are in turn attached to the ends of the lever-arm B. These wires are kept taut and properly adj usted with reference to each other by means of the turn-buckle b.

At a point convenient to the crossing is located the post C/, near the top of which is placed the signal or alarm gong C2. This gong is provided with the two striking-hammers b b2, the handles bb* of which are crossed and pivotcd together near their longitudinal center. The upper end of the handle b is connected with the upper end of the vertical cross-arm ak by means of the wire d, while the hammer end is connected with the lower end of the arm a2 by means of the wire d', the companion wiresd'l3 connecting the strikinghammer b'l with the duplicate signal device on the opposite side of the crossing, as shown in Fig. 4.

Then a train approaches the crossing, the truck-wheels come in contact with and force down one end of the rocker-arm C, imparting a corresponding movement to the lever-arm B through the medium of the rock-shaft B, and sounds the alarm-signal on the gong by means of the connecting-wires a3 and cl and vthe cross-arms a a2, the wires a* and d serving to return the signal to a normal position as the truck-wheels strike the opposite end ol;'

the rocker-arm C, thus sounding a continuous alarm. \Vhen a train approaches in the opposite direction, the operation and functions of the connecting-wires are reversed.

Fig. 5 is a modiiication showing how the parts having contact with the truck-wheels may be constructed and arranged so as to avoid ringing the gong when leaving a station or crossing. In this case the rocker-arm only projects from one side of the rock-shaft and away from the crossing. The arm in this case does not have a direct contact with the truckwheels, but is forced down by means of the link E, connecting with the highest end of the bar E. The link E and bar E are provided with elongated slots, which provide for an endwise movement ofthe bar E', and thus avoid depressing the end of the rocker-arm when a train is leaving a station or crossing. The

spiral springs shown serve to return the parts to their normal position.

Having thus described my invention,what I a?, the wires d d, the striking-hammers b b2,

having crossed handles, as described, and the 1o signal-gong C2, al1 constructed, combined, and arranged to operate as set forth.
