To all whom it nutg concern:

Be it known that I, MICHAEL McGowAN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Railway Signaling Device, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a very simple means whereby any semaphore railway-signal when set can be made to automatically produce an alarm in a passing car or engine-cab, thus calling the attention of the motorman or engineer to a special notice of the set signal, which might perchance otherwise be overlooked, which means can be operated by night as well as by day signals.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.

Figure 1 is a side elevation of a portion of a set signal and a front elevation of a car passing the same, and Fig. 2 is an enlarged sectional view taken vertically through the roof of the car and practically on the line 2 2 of Fig. 1.

A represents the post or standard of the semaphore-signal, the arm 10 whereof is shown set or in horizontal position.

B represents a car, the roof 11 whereof at that side which is next to the signal is provided with an opening 12 therein, which opening tapers inwardly, as is shown in Fig. 2.

A striking-arm 13 extends through the opening 12 into the car and is fulcrumed on the roof of the car at the outer end of said opening 12, as shown at a in Fig. 2, and the outer end of the striking-arm 13 is of sufiicient length to engage with the outer end portion of the said arm 10 of the post A as the car passes the same. The striking-arm 13 is by preference given the vertical position shown in Fig. 1 in the roof of the car, so that it will strike the arm 10 of the signal with more or less of a positive blow; but it may be diagonally placed, if desired. The inner end of the striking-arm 13 is in engagement with the angular trigger-head 14, formed at the outer end of the hammer 15, which hammer is adapted to strike a gong 16, located within the car, the hammer being also within said car. Said hammer 15 is pivoted upon a suitable bracket 17, which has a downwardlyextending free end, and a spring 18 is attached to the downwardly-extending portion of the bracket and to the hammer, and a spring 19 is attached to the hammer andto the upper portion of the bracket. These two springs 18 and 19 serve to hold the hammer normally in a horizontalposition away from the gong 16.

When the car passes a set signal, the outer end of the striking-arm 13 engages with the set arm of the signal, and the said outer portion of the striking-arm is forced rearward, compelling its inner end to bear down upon the trigger-head 14 of the hammer to such an extent as to throw its striking end away from the gong and place the hammer under the tension of the combined springs 18 and 19. The moment that the striking-arm 13 leaves the trigger-head of the hammer the springs 18 and 19 will cause the striking end of the hammer to engage with the gong and sound an alarm, thus calling the attention of the motorman or engineer to the character of the signal being passed.

This device is exceedingly simple, it is economic, and can be readily adapted to any car or to the cab of any engine.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a railway signaling device, the combination with a signal and the display-arm thereof, of a car, a striking-arm pivotally mounted in the roof of the car, extending within the car and without the same a sufficient distance to engage the display-arm of the signal, when set, as the car passes the same, a bracket Within the car, a springcontrolled hammer pivoted on the bracket and having an angular trigger-head normally engaged by the inner end of the striking-arm, and a gong also within the car, located in the path of the said hammer.

2. In a railway signaling device, the combination with the upright of a signal and its signaling-arm, of a car, a striking-arm pivoted in the roof of the car at the side which is adj acent to the said signal, which striking-arm has a vertical position and extends beyond the car outside of the roof a sufiicient distance for engagement with the signaling-arm when set, a bracket located within the car adjacent 1o tripped by the striking-arm engaging with to the inner end of the striking-arm, a hamthe set signal-arm when the car is passing the mer pivoted on the said bracket, provided same.
