ELECTRICAL DEVICE AND cmculTf Specification of Letters Patent.

Patented March 27, 1906.

Application filed J'line 2, 1905. Serial No. 2635429.

To all whom it may concern.

Be it known that I, WILLIAM H. LANE, a

' citizen of the United States, and a resident of Westfield, Union county, and State of New Jersey, have invented certain new and useful Improvements in Electrical Devices and Circuits, of which the following is a specification.

This invention relates to electrical devices and circuits, and more particularly to such as are adapted for use in-connection with railway signaling systems.

The invention seeks, anion other things, to provide a relay of increasef reliability, efficiency, and econom of battery output. This relay may be use as a clearingwelayi or as a track-relay.

In a si naling system the clearing-relay is is usually connected to the track' one whic circuit at the exit end of the track-section, at which end is also generally located the battery. A clearing-relay is used to change a signal normally at danger from its danger to its clear position when an approaching-train has reached a track-section in the rearof the si nal. It it deenergized or unresponsive w en there is no train in the track-section and is energized or made responsive when there is a train in the track-section.

In a signaling circuit the relays are usually provided with front and back contacts, and the armature which carries the contacts must have a relatively great movement, and consequently a wide air-gap. On account of this air-gap the energy required to attract the armature from its remote or pick-up position is necessarily considerably greater than the energyrequired to'hold the armature in its attracted or pick-up position. In clearing-relays as heretofore in general use the same energ was employed to keep the armature in its old-up position that was used to move it from its pick-up position. As a result of this. the relay was not likely in many cases to respond promptly to the shunting action of a train entering the track-section at the end remote from its clearing-relay. If,

however, a train should back into'the tracksection at the end where the battery and clearing-relay are located,.it would shunt the clearing-relay and it would readily respond. This condition, however, does not obtain except in special systems of normal danger-signaling. In the usual-systems of normal danmature so as to clear the signal.

ger-signaling the clearing-relay is located at the exit end of a track-section, and therefore intervenes between the approaching train. and the clearing-relay. This rail-resistance,

sometimes amounts to as much as one ohm. When the train first enters the track-section, the entire rail resistance intervenes between it and the clearing-relay, and the shunting action of the train on the clearing-relay is therefore likely to be incomplete and so as not to readily deenergize the clearing-relay. As the train advances the rail resistance is gradually reduced, and finally at some in .definite point along the truck the rail re'sistance is sufficiently reduced to enable the train to completely shunt the clearing-relay, when it will be deener ized and drop its ar- The signal is therefore cleared when a train is at some indefinite point in the section, whereas it should be cleared as soon as the train enters the section.

According to the present invention a clearing-relay is provided which responds promptly to the shunting action of a train entering the track-section at the farther end. Tliis relay is also useful as a track -relay. A track relayis normally energizedin the ordinary signaling systems. lay is used as a track-relay, it effects a/ considerable saving of battery output, being normally energizedin a condition of comparativel high resistance to hold up its armature When my improved rei and eing energized momentarily to pick up its armaturein a condition of comparatively low resistance.

indicated by the arrow. rails at the entering end of section 2 is mag- In the accompanying drawings, forming cuit.

cludedfrom the circuit and current through I the relay passes through coil alone. This is the relay s condition of high resistance.

When moving, contact 14 is in its pick-up position and closes the brake at 14, then coils 13 and 10 are included in multiple in the cir- This is the relays condition of low resistance. In the normal condition of the trackcircuit, and as shown, current from battery passes throu the rails of section 2 and through trail-magnet 8. It also passes through coil 10 of the clearing-relay, thereby energizing it, holdin 0 en the break at contact 14, and thus eXc u es coil 13.

17 is a magnet which represents the motor or other means for operating signal 6. It is included in'the circuit with generator 18 and circuit-controllers l9 and 20. Circuit-controller 19 is operated by clearing-relay of section 2 and is normally open, as shown. Circuit-controller 20 is operated by track-magnet 21 of track-relay for section 3 and is normally closed. Generator 22, circuit controllers 23 and 24, and magnet 25 operate in the same way with reference to signal 5 as do generator 18, circuit-controllers 19 and 20, and magnet 17 with reference to signal 6. Generator 26, circuit-controllers 27 and,28, and magnet 29 operate in the same way with reference to signal 7.

30 is the track-battery for section 3. This section has a' clearing-relay and associated parts in all respects similar to that of section '2. Coils 31 and 32 correspond to coils 10 and 13, and moving contact 34 corresponds to moving contact 14. 1

The operation is as follows: A train entering section 2 shunts magnet 8, thereby opening circuit-controller 24 and putting signal 5 to danger behind the train in the usual way. At the same time coil 10 of the clearing-relay is shunted, thereby causing moving contact 14 to dropfrom its hold-up to its ick-up position, so as to include coil 13. en coil 10 was shunted, circuit-controller 19 was closed, thereby ener izing magnet 17 and putting signal 6 to "sa ety in front of the train. When the train passes out of section 2, battery 9 energizes magnet 8, thereby restoring circuit-controller 24 to its normal closed position. Battery 9 also energizes coils 10 and 13 in multiple, thereby causing moving'contacts 14 and 19 to move from their pick-up to their hold-up positions.

When contact 14 so operates, it breaks the circuit through coil 13 and excludes it from the circuit, thus restoring the clearing-relay and all the other parts associated with section 1 to their normal condition. When the train enters section 3, it operates upon the track-relay and clearing-relay for this tracksection in the manner already described With reference to section 2, putting signal 6 to danger behind the train and signal 7 to safet in front of the train.

Wit reference to the clearing-relay it will be observed that when current is traversing one coil alone, as coil 10, the relay has just sufficient power, magnet 8 being in multiple with it, to hold up contacts 14 and 19 and that as soon as a train enters the track-section, as section 2, the hold-up energy of the magnet is so reduced by the shunting action of the train that contacts 14 and 19 at once drop to their pick-u positions, whereupon signal-6 is at once 0 eared. observed that when the train passes out of section 2 battery 9 supplies current to magnet 8, as usual, and with the resistance of this magnet added to the circuit in multiple with the clearing-relay the proportion of current flowing through the multiple coils' of the clearing-rela will be increased sufficiently to enable the c earing-relay to pick up its contacts at once. 7

In Fig. 2, 35 and 36 are track-sections which consitute the block guarded by the sig nal 37, this signal bein normally at safety. The signal is operate or controlled b ma net 38 in circuit with circuit-contro ler 39, operated by track-relay 40. Track-relay 4O has,two coils 41 and 42, coil 41 havingits ends connected to

wires

43 and 44, leading to the rails of section 35, and coil 42 having one end connected to wire 43, and its other end connected to wire 44 through normally

open contacts

45 and 46. Contact 45 is connected with and operated by the operating-rod 47 of signal 37. At the exit end of sectlon 35 the rails are connected by circuit-wires leading through battery 48 and normally closed circuit"-controller 49. 50 is the trackrelay connected withsection 36, having

coils

51 and 52, corresponding'to coils 41 and.42.

Coils

51 and 52 are connected on oneside to trackwire 53. These coils are connected on their other side to track-wire 54, coil 52 passing through normally 0 en contacts 55 and 56,

which are controlle by the track-relay, this latter being energized by battery 57'. In the operation of the 'device shown in Fig. 2 a train entering section 35 shunts the trackrelay 40, putting signal 3 7 to danger behind the train. The movement of the signal to danger closes

contacts

45 and 46, which thereby include coil 42 in closed multiple with coil 41. 36, it shunts track-relay50, thereby opening circuit-controller 49 and continuing signal 37 It will also be When the train enters sectlon I at danger. It also drops circuit-controller 55 to its pick-up position, thereby including coil 52 in closed multiple with coil 51. When the train passes out of the block, track-relay 50 has its coils energized in multiple,'so that contact 55 moves to'its hold-up position and cuts out coil 52, contact 55 being then kept in its.

hold-u position by coil 51 alone. Circuitcontro ler 49 of track-relay 40 is also moved :to its hold-up position and closed, thereby energizing both coils of track-relay 40 in multiple. This moves circuit-controller 39 to hold-up position and closes the circuit through magnet38, thereby moving signal 37 to safety. This opens

contacts

45 and 46 and cuts out or excludes coils 42 from the track-circuit, so that circuit-controller 39 is kept at hold-up position by coil 41 alone.

It will be observed that when the track-res are carr ing out their hold-up function, ich is by ar the greater part of the time, the battery output ls considerably reduced as compared with the battery output when these track-rela s are carrying out their pickits use as a track-rela up function. his of course is due to the fact that the hold-up'function employs only one coil of the track-relay, whereas the pickup function employs both coils in multiple.

One of the chief advantages of the relay in is t . promptness with whic a train in the section operates to shunt the relay, thereby causing its armature to'move from its hold-up to its pick-up position and put the signal to daner behind the train. This results from the lncreased sensitiveness of the relay.

The contacts which 0 erate to exclude one of the multi le coils o the relays in Fig. 1 and the trac -relays in Fig. 2 operate in reality as circuit-changers, and for convenience they are thus designated in the claims.

It will be observed that the movement of a circuit-changer to the position which excludes one coil is initiated when bothof said coils are energized in multiple.

In the preferred form of my relay the multiple coils are wound on the same core.' This is the preferred construction.v
