form of the same. Fig. 4 represents a hori- The plate 8 carries a suitable insulatingzontal transverse section taken on the plane block 22, upon which block is arranged a plate of line 4 4 of Fig. 3. 23, carrying a lever 24, pivotally connected therewith. The lever 2A is provided at its upper end with an insulating-block 25, formed with an open slot or a longitudinal notch 26, inc-losing a pin 27, projecting laterally from rod 20. Extending transversely of and connected to the lever 2A are contact-brushes 28 and 29, designed in operation to contact with 3 posts 30 and 31, the post 31 extending through said block and being provided at its lower end with binding-nuts 32 for receiving the conductor 33, leading to the resistance 3A, grounded by a conductor 35 on the tube 1. A conductor 36 leads from the plate 23 to and connects with a binding-post 37, carried by andinsulated from a plate 8, a conductor 38 connecting said binding-post with any suitable form of switch 39. (Illustrated conventionally in the accompanying drawings.) A conductor A0 is designed to connect the switch when closed with one pole of battery A1, the opposite pole of said battery being grounded by a conductor A2 on the tube 1. The conductor A3 connects with the post 30 and with the windings of magnets 11, the opposite ends of said windings being grounded by conductor AA on the plate 8.

A binding-post A5 is carried by plate 8 and insulated therefrom and is connected with a conductor A6, extending to a switch A7, designed to contact with wire A0. A conductor A8 connects with post A5 and extends to one end of the windings of magnets 10, the opposite end of said magnet-windings being grounded on the plate 8 through a conductor A9.

In operation, the parts beingin the position illustrated in Fig. 1, the switch 39 is closed, whereupon current starting from the battery A1 flows through conductor AO, switch 39, and conductor 38, binding-post 37, conductor 36, plate 22, lever 2A, brush 28, post 30, conductor A3, the winding of magnets 11, conductor AA, plate 8, tube 1, and conductor A2 to the battery. The flux of the magnets 11 thus energized aflects armature 18 and swings yoke 15 upon its pivots, whereby bar 20 is thrown from the position indicated in Fig. 1 to a corresponding incline on the opposite side of the axes of rotation of valve 2, whereby said valve through the movement of the crank 13 under the action of bar 20 is thrown to an open position, permitting a charge of gas to pass through the tube 1 to a burner or set of burners, where the same is electrically ignited, resulting from the following described opera tion: hen the parts are in the position indicated in Fig. 1, the brush 28 contacts with post 30; but when said parts are swung to the position just described the brush 29 is caused to. contact with post 31 and the contact between brush 28 and post 30 is broken, whereby the circuit will be changed so that electricity flowing from battery A1 will move through conductor A0, switch 39, conductor 38, binding-post 37, conductor 36, plate 23, lever 2A, brush 29, post 31, conductor 33, re-

sistance 3A, conductor 35, tube 1, and conductor A2 to the battery. Here it is to be observed that the resistance 3A may be of any preferred material; but 1 usually employ platinum and position the sameat a suitable point relative to the point of discharge of gas for igniting the same as soon as the platln um be-' comes incandescent, owing to the excessive amperage forced theretln'ough. After the gas is lighted the said switch may be opened. \Vhen it is desired to extinguish the light or lights supplied with gas through tube 1, it is only necessary to close switch A7, whereupon current flowing from battery 1 through conouctor A0 will move through switch A7, conductor A6, binding-post A5, conductor A8, the windings of magnets 10, conductor A9, plate 8, tube 1, and conductor A2 to the battery. The magnets thus energized effect the armature 17 and swing the yoke 15 back to the position indicated in Fig. 1, whereby the supply of gas through tube 1 is cut ofl.

In Figs. 3 and A of the accompanying drawings I have illustrated a slightly-modified form of the present improved structure, said modification consisting, chiefly, in the dispensing with one of the contact-posts and the corresponding brush carried by the lever actuated by the valve-operating bar. Referring to said figures in particular, 50 indicates a suitable gas-supply tube having such supply controlled by valve 51, rotatably mounted in its casing 52, interposed in the length of saidtube. The valve is operated in a manner precisely similar to the operation of valve 2 and with corresponding elements, including the lever 53, pivoted to a contact-plate 5A, actuated by a bar 55, carried by yoke The yoke 56 is controlled by sets of electromagnets 57 and 58. The plate 5A is carried by an insulating-block 57,supported by a baseplate 58', carried by tube 50. A post 59 rises from the insulating-block 57 in position for contacting with a brush 60, carried by lever 53. A binding-post 61 extends through block 57 and plate 58 and engages plate 5A, a conductor 62 engaging said binding-post and extending to a resistance 63, connected with a conductor 6A, grounded on tube 50. The resistance 63 is preferably a platinum igniter and in operation is positioned in such relation to the discharge from tube 50 as to ignite the same. A conductor 65 leads from conductor 62 to a switch 66, which' switch is adapted to be operated for closing contact with the conductor 67, leading to one pole of battery 68, the opposite pole of said battery being grounded by a conductor 69 on tube 50. A cond uetor 7 O connects with post 59 and with one end of the windings of magnets 58, the opposite ends of said windings being grounded on the plate 58 through conductor 71. The conductor 72 connects one end of the windings 57 with a binding-post 73, said bindingpost being connected by a conductor 7A with IIO a switch 75, adapted to close contact with conl ated thereby for opening said valve, an electroductor 67. Then it is desired to open the valve 51 and ignite the charge of gas passing through the tube 50, the switch 66 is closed, whereupon current flowing from battery 68 passes through conductor 67, switch 66, conductor anddivides upon arriving at the conductor 62, part of said current passing through resistance 63, conductor 64, tube 50, and conductor 69 to the battery 68. However, the resistance 63 is as great or greater than the resistance of coils 58, whereby the greater portion of the current will flow through conductor 62, binding-post 61, plate 54, lever 53, brush 60, contact-postv 59, conductor 70, the windings of magnets 58, conductor 71, plate 58, tube 50, conductor 69 to the battery. The magnets 58 thus energized will cause the yoke 56 to swing and throw the lever 53 to one side, breaking contact between brush 60 and post 59, whereupon the valve 51 will be opened, owing to the action of rod 55, and the entire current will be caused to flow through conductor 62 and resistance 63 and back to the battery. The entire current passing through the resistance will raise the same to incandescence and ignite the charge passing from tube 50, it being understood that the resistance 63 may consist of as many platinum igniters as may be desired for igniting a cluster of lights or for igniting a single light, as preferred. When it is desired to extinguish the lights supplied from tube 50, it is only necessary to close switch 75, whereupon current flows from battery 68 through conductor 67, switch 75, conductor 74, binding-post 73,. conductor 72, the windings of magnets 57, plate 58', tube 50, and conductor 69 to the battery. The magnets 57 thus energized will affect the yoke 56 to tilt or swing the same back to the position formerly occupied and as illustrated in Fig. 3 of the drawings, whereupon the valve 51 will assume a closed position.
