TRACK DEVICE FOR RAILWAY-SIGNALS.

Original application led'November 2,

To `all whom tt may concern." Beit known tl1at'll\lAT'r1m\v M. KANE, aei'tizenl of the `United States, and a resident of'Montgomel-y, in the county of Montlgoniery and State of Alabama, have invented a'newf and Improved -Track Device `for Railwayignals,,of whichthe 'followclear, and exact description.

'This' applicatie-11 is a division of my application for railwayl signal, Serial No. `#1 -00,362, filed November 2, 1907.

tached. This trackdevice comprises a case as s hown. The inner wall 5 of thiszcaseiis f offset inwardly o r toward. .the rail at 'lts portion so as tol form a jog or'shoulder- 6 adapted to rest upon the edge-.of the rail flange?, as shown in Fig.v 3.- This shoulder 6 forms ashelf on the interior ofthecase,

,having a switch base 8 of insulating. ma-v ,-terial, said-switch base consisting of ajheavyz- {flat-plate having an-o enin 9.11ear'eine-end'`l thereof' through Whic i a p u nger` ,10 'passes jupwardlys The end Walls l0.a

provided with inwardly proj ecting lugs-1 1 l which supportithe'switch'base 8 opposite to of theease 'are thefshoulder 6,'as shown. ,Below theo en- `in'g Qthe plunger- 10 is-formed Y.with ai Xed -collar 12, and below thiscollar avhelieal or coil spring-13 vis provided. The :lower end of this spring rests upon a circular seat 14 fin the bottom of the case, as indicated. The

Iplunger 10 .passes up through'the upper wall ofthe case through asuitable stufling bor-15, and the plunger isprovided near this point of the vcase by the 'forceof thespring 413. plunger lfls formed intl?" a head 17, andgtoythis .head inclined' treadles or levei's'lS-are -pivotal'ly attached by a ivot pin 19,The outer ends of. these tread' 5f-levers 18- are attachedl pivotallyto said links being pivotally` attached On the we b of the railadjacent to t-he links 20, guide straps 21 of metal are attached; as shown. These straps 21 permit a limited swinging movement ofthe linksy in a vertical plane, :is-Will be readily understood. lnfthe upper part of the case the plunger 10 is provided with a transverse bolt 22, andv this. bolt passes-'.througlr elongated slots 23 formed in the end of a double knife electricI switch lever 24. In the illustration only one of the sides of this double switch is used. The socket 25 near theree' end ofthe switch has an electr-ic`eondueter26 attached thereto, and the pivot post 27 at the other end of the with a stop collar or stoplfwhich is norf mally held against the upper [side'of the WallY switch, and corresponding to this socket 255 i.

has a conductor28 attached thereto These 'y conductors pass to the signalyand' find exit from the case through a suitable tubular conduit 29. The switch may close two circuits instead of one, as suggested, by connecting the other side of the switch with wires, as will be readily understood.

It should be understood that the device is expected to be attachedto the outer side of the rail so that when a train passes the Wheels will strike the treadles 18 and depress the plunger against the force of the spring y13; 'this closes the switch lever 24 against the contact 25, and closes the circuit 'throughlthe conductors 26 and :28 passing to the si gnal. When the train has passed, the ring 13 raises the plunger to its normal eevated position and opens the switch.

Referringnow to Figs.k 4 and 5, the mechanism will be described by means of which the device may be operated by the opening or closing of a switch point such as that shown in Fig. 6. When used in this connection the case 31 vof the track device is preferably attached to the outer side of the rail' 32,"as shown in Fig. 4Q yThe plunger 33 which projects above the case is formed into a head 34 to which is attached the horizontal arm 35 of a vertical link 36, the said link extending down at the lvertical endwalll of the case, as indicated in Fig. 5. The lower end of this link 36 is pivotally attached to a laterally offset link 37 which extends up near the inner side of the case,

and theupper end of this link is pivotally attacliedto the horizontal arm 38 of a bell crank lever 39, 'said bell crank lever or switch point levei` having a Vertical arm 40,

-to which a link 41 is attached, and this last link is connected to the movable switch point 30. From this arrangement,.when the switch poiiL 42 is moved away from the rail 32, the bell crank lever 39 rocks and depresses the link 36 and through the link 37 depresses the plunger 34. and closes the switch within the case. In this Way the track device can be inade to close a circuit #.13 through a signal 44 which is placed ad- ]aeent to the track.

Having thus described niy invention, I

elaini as new and desire to secure ters Patent,.-

l. A track device comprising. nieans for attaching the case to'the icaihal plunger guided vertically through said cas, a coiled spring within said case disposed about said plunger and tending to hold the saine in an elevated position, a transverse bolt carried by said plunger, a switch having a pivoted lever with a slot receiving Leif Vsaid bolt, and` nieaiis for depressing said.

plunger.

2. A track device comprising a case,

an insulated switch base mounted 'in saidv ease, a spring ten( ing to hold said plunger in an elevated position, and a switch lever pivotally mounted in said case and having a piu and slot connection with said plunger.

4. A ltrack device comprising a case having an offset inner wall forming a shoulder adapted to rest upon the rail flange, an insulating base resting on theinner side of said shoulder withinsaid euse, a switch lever pivotally mounted on said ease, a vertically a case,-

guided plunger passing downwardly within said ease, a spring tending to raise said plunger, and a pin and slot connection between said plunger and said switch lever.

In testimony whereof I have signed my naine to this specification in the" presence of tivo subscribing witnesses.
