ELECTRIC GAS-LIGHTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 596,236, dated December 28, 1897.

Application filed May '7, 1897. Serial No. 635,488. (No model.)

To all whom it may concern.-

7 Be it known that we, ADRIAN LIVINGSTON BOGART, of New York, in the county and State of New York, and LE ROY S. XVHITE, of W'aterbury, in the county of New Haven, in the State of Connecticut, have invented a new and useful Improvement in Electric Gas Lighting and Extinguishing Devices, of which the following is a specification.

This invention relates to an improvement in electric gas lighting and extinguishing devices in which the energization of the electromagnet which raises the armature connected with the main gas-supply valve to open the valve also opens an auxiliary gassupply valve for feeding gas to an ignitingtube, the mechanism which opens the said valves serving to break the electric circuit for producing a spark for primarily igniting the gas flowing through the auxiliary igniting-tube, which will in turn ignite the gas flowing through the main passage.

A further object is to so construct the device that the supply of gas through the auxiliary tube will be shut oh. while the valve for supplying gas to the burner is held open.

A still further object is to provide a new and improved gas-igniting device which can be readily applied to the well-known Welsbach type of burners without in any way interfering with the structure of the said burners or interfering with the arrangement of their mantles within the chimney.

A practical embodiment of our invention is represented in the accompanying drawings, in which- Figure 1 represents a side view of a gasburner of the Welsbach type with our 1g. 2 is an enlarged back View of the igniting device and the shell or housing for the electromagnet-coils, armature, and gas-supply valves. Fig. 3 is a vertical central section in the plane of the line 3 3 of Fig. 4.. Fig. at is a top plan view. Fig. 5 is a central section through the shell or casing, the parts within the same being shown in side elevation; and Fig. 6 is a transverse section in the plane of the line 6 6 of Fig. 5.

The shell or housing is denoted by A, and it is provided with a suitable top plate or cap ing to the source of supply.

A valve B is adapted to open and close the supply of gas through the bore a of the projection a, the said valve being provided with I a stem 1), which extends downwardly into the interior of the casing A and is there provided with an armature b, which armature is fixed rigidly to the said stem and is of disk form with a portion of the disk cut away.

Two electromagnets are mounted within the casing A in position to operate the armature b when they are energized. One electromagnet comprises two coils C C and the other magnet one coil C in the present instance. A stationary plate (t is located in the casing A between the electromagnets C, C, and C and the armature I), through which plate the cores 0 c c of the electromagnets project.

Proceeding to describe the auxiliary gassupply device for feeding gas to the igniting device, a block D is secured to the top a of the housing or casing A in the present instance by means of a suitable screw (1, the said block D being provided with a gas-conduit cl therein, which gas-conduit communicates with an upwardly-extended tube (1 which tube extends upwardly the desired distance toward the burner-tip. The upper portion (1 of the said tube is preferably made of some material which will allow of the said portion being bent to direct the flame directly to the burner. The said upwardly-extended tube is provided with a suitable opening cl, located near the sparking device to be hereinafter described. The gas-conduit 6 extends from the interior of the casing A to the interior of the block D, the flow of gas therethrough being controlled by a valve E, the downwardly-extended stem 6 thereof passing through the said conduit 6 and from thence downwardly through the plate a into position to be engaged by the armature b when l armature b, therebyopening'the valves l3 and V E. This raising of the valve E will rock the the same is raised and partially rotated by the energization of the electromagnet C C. A suitable spring 6 tends to hold the valve E snugly against its seat, except when the same is positively opened.

Proceeding to describe the sparking device for igniting the gas in the auxiliary supplytube, a stationary contact-piece F is secured rigidly to the top a of the casing A, but insulated therefrom, the said contact-piece being provided with a laterally-extended pin f, located in close proximity to the opening d in the auxiliary tube (1 This contact-piece E is electrically connected with the electromagnet C O in any suitable manner.

A rocking contact-piece F is provided with a laterally-extended portion f, which rests upon the top of the block D and extends around the uprising tube (1 The contactpiece E is further provided with a laterallyextended pin f which is held normally in contact with the pin f of the contact-piece F. The laterally-extended portion f of the 0011- tact-piece E extends to a point over the auxiliary valve E, and the said valve is provided with an upwardly-extended stem 6 which extends through the upper wall of the block D into contact with the forwardly-extended portion of the wing f, so that when the valve E is raised the contact-piece F will be rocked and the circuit through the pins f f broken. The rocking contact-piece F is normally held in contact by means of a suitable spring f which embraces the tube (1 and bears against the top of the wing f or" the said rocking piece.

The plate a, within the housing A, is provided with a suitable stop or hook a and the armature b is provided with a suitable hook N, which hook is adapted to engage the stop a when the armature b has been raised and partially rotated for holding the valve B open until the said armature has been rotated in the opposite direction and allowed to drop.

The top a is provided with a pair of binding-posts a to which may be secured the wires running to any suitable electrical actuating meanssuch, for instance, as a battery.

The electric circuits are as follows: The circuit for opening the valves 13 and E passes from the wire attached to the binding-post a through the electromagnet-coil C, from thence to the electromagnet-coil C, from thence to the stationary contact-piece F, from thence to the rocking contact-piece F, and from thence to the casing A, to the gas-pipe, and to the ground. The electrical circuit for closing the valve B passes through the wire attached to the binding-post M, from thence through the electromagnet C and from thence through the plate a and casingA to the gas-pipe, and from thence to the ground.

In operation when it is desired to light the gas the electromagnet O O is energized, which energization will raise and partiallyrotate the contact-piece F and cause a spark to ignite the gas escaping through the opening (1 in the tube (1 The flame thus formed will shoot upwardly and ignite the gas escaping through the upper end (1 of the tube (1 From thence the flame will shoot upwardly in position to i nite the gas flowin g through the main burnertip. \Vhen the magnet O O is deenergized, the armature b will fall a short distance until stopped by the engagement of its hook b with the stop a this downward movement of the armature being sufficient to permit the valve E to close, but will retain the valve B open. \Vhen it is desired to extinguish the gas, the electromagnet C is energized, which energization will rotate the armature Z) sufficiently to release this hook b from engagement with the stop a. The electromagnet is thus deenergized, thereby permitting the armature Z) to drop and close the valve 13. This partial rotary movement of the armature Z) is caused by having a portion of the same cutaway, as shown in Fig. 6 in dotted lines, whereby the effect of the magnet C C, when energized, will tend to raise and partially rotate the armature in one direction, and the effect of the energization of the electromagnet C will tend to cause the armature to rotate in the other direction.

The tube d may be extended to any desired height, and if it is found that the flame from the escape-opening d will not flash to the top of the said tube other openings (Z may be formed in the upper portion (Z of the tube for leading the said flame upwardly to the top of the tube.

By locating the igniting device entirely out side of the chimney all liability of the mantle within the chimney to become torn or injured through the movement of the contact-pieces is done away with, and also the said device may be easily applied to any of the burners now on the market without changing them in any degree.

In operation when the electromagnet C G is energized the movement of the circuit through the contact-piece is being constantly made and broken, thereby opening and closing the valve E, whereby a flashing of the flame through the auxiliary tube (Z is obtained, which flashing produces a better and surer result in that the top (1 of the tube need not be placed so near the burner-tip as where a steady flame is required to light the main flame.

The igniting-tube (1 if so desired, may be extended up exterior to the chimney and have its upper end located in position to ignite the gas from the burner-tip from the top of the chimney. \Vhile we have mentioned a single burner in connection with this device, it is evident that the said device may be employed to light a plurality of; burners, and it is also evident that the igniting-tube maybe branched or extended to any desired point.

Vhile we have described this device as particularly well adapted for use with a VVelsbach type of burner, it is to be understood that the same may be employed with any burner. It is also evident that slight changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of our invention. Hence we do not wish to limit ourselves strictly to the structure herein set forth; but

What we claim is-- 1. In an electric gas lighting and extinguishing device, a burner, a gas-supply-controlling valve provided with a stem, an armature secured to the said stem, an electro magnet for actuating the armature to open and close the valve, an igniting-tube, an auxiliary gas-supply-controlling valve therefor, the said auxiliary valve being located in po sition to be engaged and opened by the said armature when the electromagnet is energized and a sparking device under the control of the movement of the auxiliary valve, substantially as set forth.
