' RAILWAY-SIGNAL;

Specification of Letters Patent.

Application filed May 14, 1906. Serial No- 316,84Z.

Be it knownthat I, STEPHEN D. MOMA- LHON, a citizen of the United States, residing in Genoa township, in the' county of Delaware and State of Ohio, have invented certain new and useful Improvements in Rail- .'way-Signals;"and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to "make and use the same. 1 My invention relates to improvements inautomatic signals for railways; and it con- 'sists in the novel construction, combination,-

and arrangement of devices herein shown and described.

The object of the invention is to provide a simple and efficient means'for automatically operating a signalwhistle upon a locomotive. or the like as it approaches a crossing, sta-v tion, or other point where-it is' desired to give a signal or warning.

The above and other obj ect's, which will appear as the natureofmy invention is better understood, are accomplished by means.

of the construction illustrated in the accompanying drawings, in which Figure 1 is a view of 'a portion of a locomotive, showing the application of my improvements thereto. Fig. 2 is a detail plan view of a portion of a railway-track, showing the arrangement .of the trip for operating the whistle 'or signal upon the locomotive.

Fi 3 is a detail vertical sectional view taken'o n the plane indicated by the line 3 3 of Fig. 1, and Fig. 4is a detail horizontal view taken on the plane indicated by the line 4 4 of Fig. 1.

Referring to the drawings by numeral, 1 denotes a whistle or other signal suitably mounted upon a locomotive or the like, and 2 denotes my improved mechanism for auto-' matically operating the same. anism is actuated by a suitable trip device 3, located along the track over which the locomotive or car passes, and it comprises a bellcrank 4, one arm 5 of which is disposed ver-' tically to coact with the trip device 3 and the This mechproviding nuts 9 upon the screw-threaded portions of said rod, as clearly shown in Fig. 3. The bell-crank 4 is pivoted at its angle, as shown at 10, upon the outer endof a horizontally-slidable plate or element 11 which is mounted to slide in guides 12, secured upon.

one side of the fire-box of the locomotive or at any other suitable point upon the latter. These guides 12 are preferably in the form of angle-brackets which have .their horizontal portions bent to form guide-grooves to receive the side edges of the plate 11, (shown in Figs. 3 and 4;) but they may be of any other suitable form and construction. The arm 5 of the bell-crank has a cushioned connection with its supporting plate or element 11, formed by providing 'a semicircular or arc-shaped rod 13, which asses through openings in the arm 5 and t e plate 11 and has its curvature concentric with the pivot Upon said rodbetween said arm and late 'is a coilsprin 14, and upon said rod 'etween the upper face of the plate 11 and an adjustable nut 15 upon the threaded upper end of said rod isa coil-spring 16. A second adjusting-nut 17 is provided upon the lower threaded end of said rod upon the outer face of the arm 5, as shown in Fig. 3, so

that said springs 14 and 16 cushion the swinging movement of the bell-crank. The

supporting plate or element 11 is slidably mounted to permit the device 2 to be swung inwardly and out of the path of the trip device 3 upon the track, so that the whistle will not be sounded when the locomotive is backed. The plate or element is shifted for this ur ose by means of a crankarrn 18,

'PIOVldG upon the lower portion of a vertical shaft 19, mounted in suitable bearings in a bracket 20, secured upon the fire-box. This crank-arm 18 has its downwardly-bent. end rojecting through an opening or slot in the inner portion of the plate 11, as shown in Fig. 4'. Upon the upper end of the shaft 19 is a crank 22, which is connected by a link or .the like, 23, to the'reversing-lever 24 of the locomotive or to any other suitable lever or operating device. It will be seen that when the lever 24 is shifted to reverse the engine or motive power of the locomotive the supporting-plate 11 will be moved inwardly to swing the arm 5 of the bell-crank out of the path of the trip device 3.

The trip device 3, which is adapted to be arranged adjacent-to a crossing, station, or other point at which it is desired to sound an alarm or signal, is preferably in the form of a bar 25, bent to form one or more laterallyprojecting cams 26 and secured to a second straight longitudinally-extending bar 27. These bars are supported upon brackets 28, secured upon the cross-ties, either upon the inner or outer side of one of the track-rails. It will be understood that the cams 26 may be of any size and shape, and any number of them may be provided, so as to vary the length and character of the signal to be sounded. It will be understood that this signal device may be employed upon suburban and interurban or street cars propelled by electricity, steam, or any other power. If desired, an oiler may be provided upon the trip-lever to reduce friction.

The construction, operation, and advan tages of the device will be readily understood from the foregoing description, taken in connection with the accompanying drawings. It will be seen that the device may be used upon any kind of railway-lines, and that the signal-usually sounded. bythe engineer as he approaches a station or crossing will be automatically given. The whistle or signal 1 is preferably an auxiliary one, so that the engineer may give other signals in the usual manner with the ordinary whistle.

While I have shown and described the preferred embodiment of my invention, it will be understood that I do not limit myself to the precise construction herein set forth, since various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined by the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Let- I ters Patent, is

1. A locomotive or the like having a laterally-extending supporting-guide, a laterallyextending slide movable in and supported by said guide, means to move the slide in either direction in said guide, a bell-crank tappet device pivotally mounted in the slide and having a vertical arm and a horizontal arm, a cushioning connection between the said tappet device and the slide, a signaling device, and an operating-rod connecting the same and the horizontal arm of the tappet device, substantially as described.

2. The combination with a trip device mounted adjacent to a track, of a locomotive or the like having a reversing element, a signal carried by sald locomotive, an operating device for said signal carried by said locomotive and adapted to be actuated by said trip device, and-means actuated by said reversing element of the locomotive for moving said operating device to an inoperative position.

3. In combination with a trip. device ad jacent to a railway-track and having laterallyprojecting cams, a locomotive or the like having a signaling device, a laterally-shiftable tappet device for operation by said cams, means to so shift such tappet device, and a connection between the tappet device and the signaling device, to operate the latter.

4. The combination with a si naling device of a locomotive or the like, of a support, a lever pivotally mounted upon the latter and having one of its ends disposed in the path of atrip arranged along a track, a segmental guide engaged with said lever and said bracket, springs upon said guide on each side of said bracket, to cushion said lever, a whistle-operating rod having one of its ends projecting through an opening in the opposite end of said lever, and springs upon said operating-rod, on each side of said end of the lever, to yieldably connect said rod to the latter, substantially as described.

5. The combination with a trip arranged along a track and formed with a cam portion, of a support secured upon a locomotive or the like, a bell-crank lever pivoted upon said bracket and having one arm projecting into the path of said trip, a segmental guide disposed concentrically with the pivot of said lever and slidable in openings in said arm of the lever and in said support, coil-springs upon said guide, on opposite sides of said support, adjusting-nuts upon the ends of said guide, and a whistle-operating rod having one of its ends yieldably connected with the opposite end or arm of said bell-crank lever, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

STEPHEN D. MoMAI-ION.
