Appneatien ala March 12, 1910. serial No. 548,810.

To all whom *it may concern.:

. Be it known that I, J osnrn W. ROGERS, a citizen of the'United States, residing at Woodbury,v in the county of Gloucester, State of New Jersey, have invented an Au` tomatic Signaling Mechanism, of which the following is a specification.

This invention is an automatic signaling mechanism designed primarily for .railway crossings, particularly for use 'withtrains operating in both directions on a track.` 'I

The apparatus comprises t-wo starting relays located respectively ori opposite sides of the crossing and a signal relay located atthe crossing.

vThe desired result eii'ected by my invention is the automatic operation of a signal by a train as it approaches the crossing from either direction and the automatic discontinuance of the signaling operation after the train has reached a desired point or after the lapse of a desired period.

The characteristic construction and functions of the invention are fully dis-closed in the. following description and the accompanying. drawings in illustration thereof.

' Contact point d, the conductor o containing- 'In the drawings, Figure .1. is a diagram matic representation of my lmprovements;

-' and Fig.,-2 is a-diagrammatic representation of. a modified construct-ion for cutting out the signal.

The invention-as illustrated in Fig. 1 is applied to a track comprising the conductlng sectionswA, -A and A2 insulated by non-V conducting sections A5, A", A5 and A".

A rail of the section- A is divided by insulation a intosections a2 and a and a rail of the section A2 is' divided by insulation a* v into sections a. and fof. vThe section A is provided with-a starting relay comprising a battery B connected by a conductor b wlth the rail a7, and by the conductor-c with a the electro-magnet e. A conductor-7c connects the conductor c with the rail section aa and contains th'e electro-magnet g. A conductor is tapped onto the 'conductor f and is provided with the contact point z'. A conductor j connects the railsection a2 with an armature lc adapted to oscillate between the contacts l and t, means such as a spring m serving to hold the armature 7c in engagement with .the contact Z normally. On the opposite side of the crossing is the second starting relay comprising the battery B, the

conductor b connecting it with therail section a8 and thel conductor-o connecting it with the contact lpoint d', .the conductor c containing the electro-magnet e. A 'conductor f connects the Wire c .with the rail section a and contains the electro-magnet g. A conductorl h connects the conductor f with .the'contac't point z". A conductor j" connects the rail section a with an armature la which is adapted to oscillate between the` contacts cl and means such as a coiled spring m being provided to hold this armature in engagement with the contacty d nor mally. i

The electro-magnet is adapted for attracting an armature n to effect its'engagement wlth the contact point o, the armature being-held normally out of engagementwith the electro-magnet'and contact point by i suitable means as a spring p. A conductor g-connects the armature n with a conductor R and a conductor s connects the contact point o .with a conductor T.

The electro-magnet e is' adapted for lattracting the armature 'n' and effecting its engagement with the-contact point 0,', the armature being held normally out of engagement with the electro-magnet and con# tact pointby the spring 79.. The armature 1s. connected by the conductor g" with the conductor R and the contact point oAis connected by the conductor-s with the con- I ductor T.

The crossin 4relay comprises the battery v the conductor b2 withthe B2v connected conductor Tand by the conductor o2 with the conductor R, the conductor c2 containlng the electro-magnet e2. A conductor d 4connects the conductor b2 througha coiled spring da with an armature f2 adapted to be attracted by the electro-magnet 'e2 against the action of a, spring da which normally withdraws it from the electro-magnet.

A contact point g? is connected through the resistance coil h2 with the conductor c2 on one side of the electro-magnet e2 and a con- `tact. point '2 is' connected through the bell J with the conductor o2 on the other side of this electro-magnet, these contact points being engaged by the armature f2 when the latter is .attracted `by the electro-magnet e2. The resistance is used to prevent short circuiting the'ba'ttery and to reduce the potential across the terminals of the magnet corresponding thereto. Conductors u and u' connect Athe terminals of the electro-magnet e2 with the respective rails a and a ot the section A.

In operation, with a train direction of the arrow, when it reaches the track section A a circuit of the battery B is completed through the wheels v and the axle Q1 connecting the rail sections a2 and a7,

upon which current flows through the con-` ductors b, al, c, "v, o, a2, y', 7c, and c, exciting the electro-magnet e and drawing the armature/nl into engagement with the contact 0. This completes a circuit of the battery B2 and current flows, therefrom through its conductors b2, T, s, n, g, R and c2, exciting the electro-magnet e2. This electro-magnet now draws the armature f2 into engagement with thel contacts g2 and 2. Current now Hows through the resistance and signal circuits, from the battery B2through the conductors b2, (Z2, and f2 to the contacts g2 and 2, the current diyiding here so that part of it returns to the battery by way of the resistance coil h2 and the electro-magnet e2 and the remainder by way of the circuit of the signal J, the latter being sounded.

When the train has passed the insulation a, the circuit containing the electro-magnet c is broken and the armature n is released, breaking the circuit of the battery E2 con'- taining this armature. In this position of the train, the circuit containing the electro-- magnet g is closed and the armature if: is

- withdrawn from the contact point cl, without however effecting the operation of the signal.' T he' bell continues to ring until the train reaches the track section A when the signal is discontinued by the connection of the conductors uand u through the wheels 1f and axle c. lCurrent now flows from the battery B2 through the conductors b2, (Z2, f2, u, 0, Q1', '0, u and c, cutting'out the electro-magnet e2 and permitting the spring d3 to .withdraw the armature f2, which breaks the bell circuit. The train passes the second starting relay without ringingthe bell because when the rails of"v and as areconnected current Hows from the battery B through the conductors b', as, u', fu', 1), a5, f and c, exciting the electro-magnet gvwhich attracts the armature lc. This withdraws the arma- 'ture from the contact d, consequently the circuit containing the electro-magnet e is broken and the armature n remains in its moving in the The mechanism shown in Fig. 2 represents amodiiied construction orcutting out the signal after the lapse of a predetermined period of time. In this construction a conductor c4 connected with the contact 'i2 is wound upon a metal coreA w contained in a box w of the same material, the box having a contact lw2 connected by the conductor 03 with the conductor 02 and electrically separated by .insulation w3 from the conyducting material of the box. A conductor c5 connectsthe box fw with the conductor c2 so as to cut out the electro-magnet e2. When,

as previously described, current flows backl y to the battery through the conductor c2, exciting the electro-magnet ve2 and drawing the armature f2 into engagement with the contacts g2 and i2, the signal J is sounded by current lowing'throughthe conductors b2, di', f2, and 2 back to the battery by way of `the bell circuit. At4 the same time current flows vthrough the conductor c4 through the coil around the core w, heating and expandving the latter so that it is brought into engagement with the conductor cu2. Current now flows by way of the conductors c5, w', w, 102,03, and c2 to the battery, cutting out the electro-magnet e and releasing the armature f2, broken.
