i e all whom it may concern Be it known that I, Hersss A. @siicim. a Cl'iiin of the United Slates of '.nei'icsi..

residing at the city 09? St. il cscpii. in the county of Buchanan aml Stale 0i Missouri, have invented. certain new and usefzii Timpi'cvemcnl's in Automatic Railway Usage!- Signals, GfWlliCll the 'fcllmving is a specification.

The object. of invcnticn is :0 provide an autmnstically cpci aieil.

Similar loilcrs refer to similar pail-is in tlic several vicws.

in said drawings A i are the tracks of a railway and A A the ties thereof.

D and D are electric switch boxes placed alongside a track pr cier-x3223 at opposite ends of black and at in'tcimecliate points iEQCl, each box being prnvirlccl with :1 lunged (1002 (Z. Said electric switch boxes arc rigidly aiiaclied to rail A by iJI'HQS a (F. A cmn'lnit f0! wires has ccnnectimi between said SWliCii boxes alongside the {rack within which the necessary wires are securely limlserl from being; tampercdwith and from any damage.

J J are guides (Micheal to a metal rim K which is px cfembly cast in the form 02'? a segmentcif circle; these guides opcrizie through apertures J J in the switch box, as slimvn in M is lmid the same in position. P s & gn-cssm'e spring shat holds operating pawl in place. Q2, 0 and Q are conflict fastened to circuit controlling wheel M and. which is operaliecl by ths commined mevcmeilt of said circuit controlling wheel, rad L and operating pawl M which iowm ciintaci alici'nalcly Wiih Contact paints and R. S is a pin i0 release said operating pswi iii any given point Where it mnv be necessary to operate said circuit controling wheel M, and S is a pin which holds pawl O in place. I I are rellers 01 Wheels suppcrte on each side of a locomotive by arms I I. or similar means. Gnc of said the wires in the conduit, rings the bell in the tower, and operates the lights 1n thetower and at the switch stations.

The operation or my system is as follows:

When aroller I of an engine strikes a rim K and rod L has been raised a suliicient height to operate pawl M, as hereinbefore set forth, the movement revolves circuit controlling wheel M and places it in position. The current then passes from the carbon side'of the battery through wire 2' and contact point brush it in electric switch box D through the plate (not shown) on the back of said circuit controlling wheel M through contact point Q in'contact point B in said electric switch box '1) through, wire j to contact point R in electric switch box D through contact point Q in contact point R in said electric switch boil: D through plate (not shown} on the back of circuit controlling wheel ill in electric switch box D, thence through contact point brush it in switch box 3D through lVlIf JLtO thB zinc side of the battery. It the engine goes on through, and

roller 1 hits rim K on electric'switch box I).

it breaks the circuit at contact points Q and R and puts contact pointQ in contact point It in electric switch boil)";

W hat I claim andde'sire .to secure by Let-- ters Patent, is,-- I r v 'l. ln'an' automatic railway danger signal a circuit controlling wheel having a pluraliiy of points,- a corresponding number of nine riveted in said points, a brush making liding contact on said wheel, three equally iced contact points on said circuit controlling .whcel, two diametrically opposed stationary contact points cooperating there with, an :ipcrating pawl, a movable rod havengagrm eat with said operating pawl tomore the circu t controlling wheel to connect the stationarycontacts alternately with the contacts on said circuit controlling wheel, a

pawl to hold the circuit controlling wheel in posltion when moved to point of contact, a

spring to hold the operating pawl in position to catch a pin and a guide to release the operating pawl from the pin at any desired point.

2. In an automatic railway danger signal a water proof box, a circuit controlling wheel therein, pins riveted in said circuit controlling wheel, a brush making sliding contact on. the circuit controlling wheel, electrical contacts controlled by said circuit controlling wheel, an operating pawl, a pawl to hold the circuit controlling wheel in position when the same is moved to a contact making posi tion, a spring to holdv the operating pawl in position to catch a pin, a guide to release the operating pawl at any point desired, a circular rim, a rod connecting said rim and operating pawl, guide rods attached to said rim and'stationary guides for said rods.

' 3. In an automatic railway danger signal, a water proof box, an electric controlling whecltherein, a brush making sliding contact on the hack of the controlling wheel, an operating pawl, a pawl to hold the circuit controlling wheel in position when the same is moved to a contact making position, a spring to hold the operating pawl in position to catch a pin, a guide to release the operating pawl at any point desired, a rod attached to the operating pawl, a circular rim attached to the rod, guide rods attached to the rim, and stationary guides for the rods 4. In an automatic railway danger signal a circuit controlling wheel, a plurality of pins riveted in said wheel, a brush making sliding contact on said wheel, an operating pawl engaging the pins on said wheel, and strips carried by said wheel, stationary contacts engaged thereby, a movable rod connected with said operating pawl to move the circuit controlling wheel, a'semi-circular rim attached tosaid rod, guides for said rim, a pawl to hold the circuit controlling wheel in position when moved to contact making position, a spring to cause the operating pawl to catch a pin and move the circuit controlling wheel and a guide to release the operating pawl from the pin at any desired point.

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