Application led- January 2e, 1913. Serial No. 744,714.

.To all whom it may concer-n Be it known that-I, DAVID I. KELLY, a citizen of the United States, residing at New York city, in the coun-ty of New York and State of New York, have invented new and useful Improvements in Signals, of' which the following is a specification.

The general object of the invention is to have the approaching of a railroad train to a danger signaler the passing of the train beyond.such signal, and the approaching of the train toa grade'crossing, indicated by a signal. And toftheseends the invention resides first, in providing. a car with whistle opera-ting means and a track with means for controlling the operation of the whistle operating means and arranging these parts so as to coact and eiect the opening of the whistle valve when the car is at a predetermined place on the track; amd second, in providing locking of the whistle operatingmeans upon coaction with lthe controllingmeans.

Other objectswil'lv appear' aiidbe bet-ter understood from that embodiment ofmy invention of'whiclr'ithe' following is a-ispeciii-Y cation, reference being.- li'ad to. the-accom panying drawings formingpart hereof, in which- Figure 1 is a side` elevation-oa railway locomotive equipped with lone embodiment of my invention.

- at right angles to Fig. 1 showingzthegreater portion of the whistle operating-.Bienne and control-ling means and a sulh'cient.- portion of a locomotive to illustrate the application ofv the whistle controlling means thereto. Fig. 3 is a detail side elevation showingv the position-kof the controlling means and whistle operating means when coacting'to sound the whistle for agrade crossing. Fig. 4 is a detail horizontal section of the casing. Fig. 5 is a detail side elevation show-ing by dotted lines the position of the. means 1for effecting the locking. of the signaloperating means. Fig. 6 is a vertical cross section on the line 6 6 of Fig. :5 andshowing the j controlling means in inoperative position.

Fig. 7 is a view .similar to Fig. 6 but'show- Cn Y ing the controlling means in operative position. Fig. 8 is a contracted diagrammatic view showing the arrangement of th'e controllers for effecting the sounding of .the whistle upon approaching a grade crossing and the locking of the whistle upon the trains passing a danger signal.

means for eiecting the f i a point between the fiilcrum 10 and spring Y 117 isthe upper end of a rod 12. By pref- Fig. Qisa-viewy looking j which when closed, niayb'elocked with a key actuated,l lock v17.

l ward-ly In the embodiment shown in the drawings a indicates the whistle of the locomotive7 b-b the driving wheels, c one of the driving wheel trucks, al the track, o a semaphore signal, and f an operating lever.

ln carrying out my invention attach one end of a flexible element 5 such as a cable, to the valve rod 6 of the whistle a. rlhis flexible element 5 isv then directed through an open-ended casing or tube 7 carried by the boiler of the locomotive 8 and has its lower end connected to one end of a lever 9 whose fulcruni l()y is suitably connected to the truck o.. The other end of the lever is iel connected to the' truck by a retractile spring 11 which operates to hold the lever 9 horizontally or substantially so, in which position thevlexible element 5 will be relaxed so ias to exert litt-le or no pull onthe whistle 4 valve rod 6.-

Connected to the levert) and preferably at ,erence this rod is 'lshaped in cross' section .and is directed through a correspondingly shaped guide 13v located in a boX orv casing 14 which issuitably connected to the truck c.

`5 The saidbox having openings in opposite walls to admit ofthe passing therethrough ofl the rod12 whose lower end extends to a point-below the truck o and carries a shoe 15.

The casing-:1e isl provided with a door 16 A. gravity latch 18'located in the casing has one end directed into the path of movement-of a stud 19 carried by the rod l2 and directed through aslot in one side wall of the guide 13. When the rod 12 is in its normal posi-tionpth-e stud 19 is disposed below the latch lbut upon the rod moving upbeyond a predetermined point the stud eli'ects the lifting of the free' end of the latch untilthe latter is moved beyond the' plane of' movement of the stud, at which time the latch giavitates to normal position so as to intercept the rod by contacting with the stud and thereby prevent return move-.l nient of the rod.

Arranged between the rails of the track al are the controllers 2O andiQl for the'whistle operating means above described. The controllers 2O may be of any` preferred construction as that shown in Figs. 2 and 3 where it will be seen that the middle poris a trifle above the plane of the track rails 22-22. The controller 21 includes a section of rail g arranged so as to correspond in height or approximately. so to the track rails 22, and a trip vplate it carrying pins 23 which areconnected to pins 24 carried by the rail section g, by means of links 25. A plurality of connecting rods 26--26 connected together by'bell cranks 27-27 connect the trip plate la with` the rod 28 which connects the operating lever f with the semaphore c and an additional connection in the form of a bell crank 29 and a rod 30 is established between the semaphore and the The'controllers 2O arearranged so as to eect the sounding of the Whistle when the train is at a predetermined distance from a surfaces of these controllers arranged above the plane of the tread surfaces of the track rails 22 and in 'the path of movement of the shoe 15, it will be manifest that when such shoe contacts with the controllers suc-` cessively and the parts to which the said shoe is connected, occupy the positions shown in Fig. 2, four blasts of the Whistle will be had, the first two of these being relatively long While the second two will be relatively short, this `combination of blasts being the usual signal given when a train approachesa grade crossing. It may here be stated that the lifting etect on the rod 12 produced by the controllers 20 will not vbe to a degree sufficientto eifect the interlocking of the Studis with the latch is.

Referring now to Figs. 5 to 8 inclusive,

it will be seen that the trip plate 71, is ar ranged so as to operate in unison withthe semaphore e, the connection being such that when'the semaphore is adjusted to indicate a clear track the said trip plate will occupy the position shown in Fig. 6, that is to say, its uppersurface will be coincident or substantially so, with the rail section g and the Copies of this patent may be obtained. for

until the stud 19 interlocks with the latch.

18. Now the whistle will sound even when the shoe is carried beyond the controller 21 and in fact until the latch 18 is disengaged from the stud, which, it will be observed, can be only eected when the train is brought to a standstill and the conductor or other operative in possession of the key, un#

locks and `opens the door 16 and operates the rod 12 and latch 18 to effecty the disengagement of .these and permit the rod to move to its normal position.

In arranging the Whistle operating Vmechanism care is given to have the casing 111 disposed so that when the door thereof is open its interior will be readily accessible to a person occupying a position at the sides of the Wheels.

What is claimed as new is:

In combination with a vehicle having a signal, a vertically movable'shoe carried by the vehicle, means operatively connecting the shoe with the signal a member fixed in the path of the vehicle and projecting into the path of the shoe, the'shoe being free to return to a normal position after being displaced therefrom by contact with said member, a strip Inova-bly mounted on said member, and adapted to be projected beyond the edge thereof into the path of movement of the shoe, means of moving said strip, and a lock mounted upon the lvehicle vand adapted to retain the shoe in an abnormal position after it has been displaced from its normal position by contact with the strip.

In testimony whereof I afhx my signature in presence of two witnesses.

A DAVID I. KELLY.
