i 7 Application filed Decem'ber'Z, 1914. Serial No. 875,182.

Two oppositely disposed electro- magnets 1 and 2 are'spaced sufficiently apart by 7 means of hollow member'3 to permit valve l to operate therebetween in controlling the flow of gas to burner o, the hollow portion of the said member 3 being adapted to form agas-chamber between said two magnets.-

Llectro-magnet 1 may have ts core 6 formed of a pipe or tubing of any suitable metal for the purpose, such, for instance, as soft iron, said tube having its channel 7 adapted to connect the hollow portion of member 3 with the channel of gas supplypipe 8, an end of said core protruding beyond an end of said magnet and being connected to an adjacentend-of said gas supplypipe 8 by any suitable means, such, for in-..

stance, as by means of union 9, there being the usual coil end-plates 10'and 11 composed of any suitable insulating material, such, for instance, as vulcanized rubber.

Magnet 2 may be constructed similarly to magnet 1, and tubular core 12 of magnet 2 is adapted to provide communication by means of itschannel'13 between the hollow portion of member 3 and the burner-bearing pipe 141, an end of said core protruding beyond an end of said magnet 2 and being connected to an adjacent end of said burnerbearing pipe by any suitable means, such, for instance. as bymeans of coupling 15, there being the usual coil end- plates 16 and 17, similar to the end-plates 10 and 11 above described.

Valve 41 may be slidably supported, preferablv in a vertical position, in the gaschamber of hollow member 3 by means of a bearing 18, said bearing being secured to the inner wall of member 3 in any suitable manner, and may divide the gas-chamber of said member 3 into two substantially equal portions, as shown in Fig. 1, and communication between said two portions of said gas-chamber may be established by means of a plurality of perforations 19 through said bearing 18. Valve 4e is adapted to form an armature for magnets 1 and'2, and may be constructed of any suitable material for that purpose,,such, for instance, as soft iron, and may have a central portion 20 composed ofbrass or any other non-magnetic material, the head end :21 and the valve-bearing end 22 of said valve 4 being secured to adjacent portions means, such, for instance, as by means of being forced upon shoulders 23 and 24,'respectively, of said central portion 20.

Valve-bearing end 22 may be a conical valve, as shown in the drawings, adapted to seat in conical valve-seat 25, said valve-seat being borne by the adjacent end of core 12, and said valve being adapted normally to seat in said valve-seat by gravity to shut off the flow of gas from the gas-chamber of hollow member 3 to burner 5.

A spring member 26 may be. borne by a surface of said bearing 18 adjacent to the head end 21 of the valve 4, said spring-member having a latch-portion 27 adapted to en gage a notch or annular groove 28, said notch or annular groove being near the end of head end 21 of valve 4 opposite magnet 1, said latch-portion 27 of said springmember being adapted to support said valve 4 mechanically in unseated position in relation to its valve-seat 25 when said valve is drawn toward magnet 1, as hereinafter described, said latch-portion 27 being adapted, also, to limit the motion of said valvetoward magnet 1 so that the end of head end 21 of said valve may not'come in contact with the adjacent end of core 6 and may not close channel 7 of said core. Moreover, spring-member 26 maybe provided with an inwardly-turned portion 29 adjacent to latch-portion 26, said inwardlyturned portion 29 being adapted more posi-' tively to limit said movement of said valve toward said magnet 1, the purpose of the mechanism provided for limiting said movement being to provide at all times egress or" gas from channel 7 into the gas-chamber of hollow member 3 and to prevent the end of head end portion 21 of valve 4 from closing the opening of said channel.

A casing 30 adapted to inclose the valve mechanism and associated parts above 'described may be provided and may be held in place by means of a plurality of screws 31 attaching said casing to end plates 10 and 17. An opening 32 may be provided in end plate 10 to permit the passage from without into casing 30 to magnets 1 and 2 of wires 33 necessary for electrically wiring said magnets.

Burner 5 is provided with the usual means for producing a spark, which means may be a member 34 made of platinum or any other suitable material and attached to said burner in an appropriate position by any suitable means, such, for instance, as by means of a band 35 about gas pipe 14 and a screw 36, there being an insulating member 37 of mica or any other suitable material interposed between said pipe and said band. 7

Referring particularly to Fig. 5 showing a diagrammatical view of a system of electri *al circuits used in operating the device embodying the present invention, 38 is a battery, 39jis a push-button whereby the normally-open circuit for igniting burner 5 may be closed, 40 is a push-button whereby the normally-open circuit for extinguishing a light at burner 5 may be closed, and 41 is the spark-coil for producing the spark at member 34 for igniting gas issuing from burner 5 when push-button 39 is manipulated to close the circuit for lighting said burner.

W hen button 39 is pressed to close the circuit. for lighting burner 5,- two circuits are synchronously closed, onein the course of the arrows with the solid-line shafts energizing magnet 1, and the other in the course of thearrows with the feathered shafts passing throughsparking-coil 41 and producing the ignition spark from member 3-4 to burner 5. l Vhen button 40 ispressed to close the circuit for extinguishing the light at burner 5, a circuit is closed in the course of the arrows with the dotted shafts ener gizing magnet 2.

Normally the position of valve 4 is that shown by the solid lines in Fig. 1, whereby said valve is seated in its seat 25, thus shu ting oil the flow of gas through channel 13 to burner 5. When it is desired to light said burner, button 39 is pressed to close the lighting circuit, whereupon magnet 1, is energized, which, acting'upon its armature, valve 4, draws said valve toward said magnet 1 and 'nnseats said valve from its seat 25,

permi ting gas to flow from the gas-chain member coming in contact with the end or" head end poruion 21 of said valve, button 39 having been released, valve 4 will be held mechanically by means of said latch portion in unseated'position, shown by the dotted lines in Fig. l, in such manner that gas will continue to flow through channel 7 into an adjacent portion of the gas-chamber in hollow member 3, thence through perforations 19 to the portion of said gas-chamber adjacent to the valve-seat 25, into channel 13, and to burner synchronously with the closing of the circuit which energizes magnet 1, and by the samepressure upon said button 39, a circuit is closed which energizes sparking-coll 41 and produces an ignition spark from member 34 to gas issuing from burner 5, thus igniting said gas. 7

It is, of course, understood that it is necessary to close the igniting circuit and the circuit for energizing magnet 1 only momentarily, for as soon as magnet 1 has drawn valve 4 to unseatetl position and the ignition spark has ignited burner 5, pressure upon button 39 for closing said circuits may be removed, whereupon said circuits will be broken and magnet l and sparking-coil 41 will no longer be energized, while valve 4 will be mechanically held in the position shown bydotted lines in Fig. 1, as l1ereinabove described.

When it is desired to extinguish the light at burner 5, button 40 may be momentarily pressed to close the extinguishing circuit shown by the dotted arrows in Fig. 5, thus energizing magnet 2, which will draw valve *Il toward its seat and out of supporting engagement with the latch-portion of springmemberib, whereupon said .valve resuming its normal position seated in valve-seat and being held in that position by. the force of gravity, the flow of gas to burner 5 will be cut on and the light will be extinguished.

A as-lighter and extinguisher embodying the present invention may be employed to V ignite and extinguish a single burner, or a plurality of burners forming one chandelier may be ignited and extinguished simultaneously thereby, each burner on said chandelier being equipped with an igniter 34 connected with the spark-coil and magnet circuit adapted to be closed and broken by manipulating push-button 39. Also, a plurality of chandeliers or individual lights upon one floor of a house or building or throughout an entire building may be equipped as hereinabove described and connected on the same igniting, magnet-energizing, and extinguishing circuit, so that all the said lights may be ignited simultaneously and extinguished simultaneously by the manipulation of one set of push- buttons 39 and 40, respectively, placed in any convenient location. Moreover, the gas burners of an entire village, town, city, or any portion thereof, may be simultaneously lighted and simultaneously extinguished from a central station by means of the present invention.

Various changes in construction and arrangement of parts may be made without departing from the nature and spirit of the present invention.
