JOSEPH STANLEY, OF HUNTINGTON, INDIANA.

AUTOMATIC SIGNALINGAPPARATUS LOCOMOTIVES.

To all whom it may concern:

Be it known that I, JOSEPH STANLEY, a citizen of the United States, residing at Huntington, in thecounty of Huntington and State of Indiana, have invented certain new and useful Improvements in Automatic Signaling Apparatus for Locomotives; and I do here'bydeclare the followingto be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which itappertains tomake and use the same. I I

The present invention relates to signaling apparatus for railway locomotives, and has for its purpose to provide a device which is automatically operable to efiect the sounding of the signal at predetermined points along the roadway whereby to absolutely insure the sounding of the warning at such places, without requiring any attention on the part of the engineer, thus leavlnglnm free to his other duties.

A further purpose of the invention is'to provide an apparatus which may be used in connection withthe usual locomotive steam: whistle, to the end of equipping any loco motive with the device without requiring any alteration in its construction; and

wherein the construction of the apparatus is-simple and may be produced at small;

cost.

With these and other objects inview the invention consists in the novel details ofconstruction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the-claims.

In the accompanying drawings forming, a part of this application, an'din which s1milar reference symbols indicatescorresponding parts in theseveral'views: Figure 1' illustrates the application of the invention to a locomotive. Fig. 2 is a detail and side elevational view of the track engaging memher and its associated parts. Fig. 3 is a verse sectional View taken on the line 66 of F ig.' l; and "Fig. 7 is a detailview, partly in elevation and section, of the steam chest and controlling slide valve.

detail, A designates an ordinary locomotive. having the usual steam dome B, and on which is mounted the whistle 1. A casing or frame 2 is mounted on the cab C of the locomotive and contains a mechanism for automatically effecting the blowing of the whistle 1 at predetermined points along the roadway; The whistle 1 isadapted to be sounded by steam taken from the boiler dome B, through a pipe 3 leading to a steam chest 4:, and from which the steam is com municated directly to the whistle through the. pipes 5 and 6. The pipe 5 is connected to communicate with the steam chest 4 at opposite ends by sections 7 and 8, as in the manner clearly shown in Figs. 1 and 7, and the purpose of which will be presently explained. The usual throttle lever 9 is fulcrumed in the cab-at 10, and is connected to actuate the slide valve 11 mounted in the steam chest 4 and adapted to control the passage of steam from the chest through members or strips 17 secured to the bottom of the steam chest and providing guideways. From the foregoingit will be clearly seen that when said throttle lever 9 is moved to its forward or reversed position, communication is established between the steam chest a and the steam pipe 5 through either of the pipe branches 7 or 8, and further, that when said throttle lever 9 is in an intermediate position (as shown in Fig.1), the slide valve 11 will close communication between the steam chest and both of said pipes (as shown in Fig. 7).

The valve 11 is connected to the valve rod 15 through the medium of a pair of lugs 11 through which said rod passes, and between said lugs a nut or pin 12 is secured to the rod and forms an abutment for the pair of oppositely acting springs 13 'whose distal ends are disposed against the lugs 11?. By this form of connection between the valve and its actuating rod said valve has a resilient sliding movement which avoids any liability of binding, and it is self-centered or seated to close the pipes? and 8 when the lever 9 is moved to its 111- termediate position.

in the ordinary running of the locomotive communication between the steam pipes and 6 is shut oil or interrupted by the l'nechanisin contained within the housing or frame 2, and comn'iunication is established between the pipes 5 and 6 to effect the sound ing of the whistle through the operation ofthls apparatus, which 1s performed automatioally.

, The casing consists of two similar sections 19 and 20 provided with two pairs of guides 21 and 22, between which are mounted a pair of grooved blocks 23 carrying a shaft 2-1- on which is journaled a wheel 25. A second pair of blocks 26 are mounted on the side members beneath the blocks 23 and provide supporting members for the latter. A cross-head 27 is mounted on the blocks 23 and carries a valve rod 281 The open spaces between the sections 19 and 20 and the valve rod are closed by the sectional block 29, secured in any suitable manner.

The pipes 5 and 6 enter the space provided for the working of the rod 28, and have their adjacent and open ends disposed in alined and close proximity. The rod 28 has a squared section. 30 which works within a suitable chamber formed-in the sectional.

block 2:), and said squared section is formed with an elongated opening or aperture 31,

.is adapted to seat against and close the end of the pipe o when the rod is at its lowermost position, 2'. 0., its normal position. Said valve 32 is mounted within a recess 83 formed in the face of the section 30, and is itself recessed to receive a pressure spring 84i- (see Fig. 6). A pair of springs 35 are disposed between the side block sections 29 and the cross-head 27, and to either side of the rod 28, and have for their purpose to act against said cross-head and hold the same under tension at its lowermost position, 0., with the valve 32 closed against the open end of the pipe 5. The wheel 25 is adapted to be raised to move the rod 28 and uncover pipe 5, wl'lereby to effect the sounding of the whistle, through the medium of raised track sections 36 that are disposed to either side of the main rails 37 and at the proper intervals along the roadway. Thus it is proposed to place these raised tracl: sections to either side of grade crossings, to the endth at the whistle will be blown automatically before reaching such crossings without requiring this to be done on the part of the engineer.

It is obvious that those skilled in the art automatically sounding the whistle comprising a steam pipe connected to the whistle; a supporting frame mounted on the locomotive; blocks slidably mounted in said frame; a rod mounted on said blocks and having opening adapted to register with said steam pipe and form a through iassage therewith; springs engaging with said frame and normally holding the rod in position 'to obstruct said passage; a wheel carried by saidbloclzs; and a raised track section adapted to engage with said wheel to move the rod and bring said rod opening into register with the steam pipe whereby to sound the whistle, substantially as de scribed.

2. The combination with a railway locomotive having a steam whistle, of means for automatically sounding the whistle comprising a steam pipe connected to the whistle; a supporting frame mounted on the locomotive and constructed with guideways; blocks slidably mounted in said guideways; a cross-head mounted to be lifted by saidbloelrs; a rod carried by said crosshead'and having an opening adapted to register with said steam pipe and forming a through passage therewith when the rodis raised; a. valve carried by said rod adapted to close the passage through said pipe when the rod is in normal position; resilient means engaging with said crosshead for holding the valve rod in normal position; a wheel carried by said blocks; and a raised track section adapted to enwith said wheel to move the rod and bring said rod opening into register with the steam pipe whereby to sound the whistle, substantially as described.
