A Application inea Apers, ist?. seri-.11 nu. 233,126. rno'moael.)

T0 all whom it may concern:

Be it known' that I, JUSTUS B. ENCLZ, of the city, county, and State of New York, have in vented new and useful Improvements in Electric Gas-Lighters, of which the following is a full, clear, and exact description.

My invention has reference to that class of burners in which the gas is automatically turned on and a spark produced at the burnertip to ignite the same on closing the lightingcircuit, and on closing the extinguishing-circuit the gas is turned off.

The invention has for its object to provide new and useful improvements in this style of burner, whereby it is rendered more compact, efficient, and economical; and to this end the inventionconsists in certain novel features of construction and combinations of parts, hereinafterfullydescribed,andparticularlypointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

yFigure l is an enlarged vertical sectional view of an electric gas-lighter embodying my improvements. Fig. 2 is a plan view of the same; and Fig. 3 is a sectional plan view ou the line x x, Fig. 1.

The threaded metal couplingsleeve tliebase of the burner is adapted to be screwed on the gaspipe, as usual, and is formed with the wide annular flange B. To the sleeve A, around its inner edge, is secured the upright tubular shell G, preferably of thin metal, the upper end of which is screwed into a recessed disk, D, forming agas-tight joint.

The disk D is formed with a wide annular flange, E, corresponding in size and parallel with that on the lower coupling-sleeve, A, and is formed with au external thread, on which is vscrewed downto the flange E, to form a gaslower electromagnetic coil, J. The two elec- Y tro magnetic coils are insulated from each other by a collar, K, of non-conducting material, surrounding the shell C, extend out flush with the outer edges of the upper and lowerv l is thus surrounded by the upper portion of the upper electro-magnetic coil, I, and forms its core-section.

The disk D is formed with a central depression, M, forming a seat for thev valve N, and

the piece M with a vertical aperture, M, leading downward therefrom, in which plays the stemN of the valve. somewhat larger than the valve-stem,.in order The aperture M2 is made to provide a passage for the gas to the burnertube G and tip I-I when the valve is open.

To the lower end of the valve-stem N is attached a soft-iron cylindrical block, O, whichl is somewhat smaller than the interior of the shell C, to leave a passage for the gas, and is adapted to move vertically therein with the valve when acted upon as an armature by the upper electro-magnet, composed of the coil I and core-section M. i

Within the upper part ofthe lower coil, J,

also is xed a soft-iron core-section, P, having a central vertical passage, P, for the gas and formed with a vertical side slot, P2, in they lower end of which is pivoted a lug on the swinging soft-iron block or armature P3. Said lug is prolonged toform a dog, Pt, which is received loosely in a side slot, O', in the, upper movable armature, O, and is adapted to automatically engage a shoulder, O2, formed at the inner side of the slot O' by the weight of the attached armature P3 when the armature O is raised by the action of the upper l magnet.

Two binding-posts, Q B, are arranged on the top ange, E, and are insulated therefrom in anysuitable manner. The post Q is oonnected withvone terminal of the upper coil, I,

and the post R by an insulated conductor, R',

ruiming downward within the outer casing, L, with one terminal of the lower coil, J. The other terminalof the upper coil, I, is connected by an insulated conductor, I', with the fixed-contact S of the spark-producer, which contact is supported on, while insulated from, the cap F in any suitable manner.

The movable contact S is of the usual de IOO seription, and is in continuous electric connection with the ground through its holdingspring S2 or its guide-tube, the cap F, shell C, sleeve A, and through the gas-pipe on which the same is held. vThe other terminal of the lower coil, J, is grounded through the sleeve A in like manner.

- To the binding-posts Q R are connected wires T V, respectively, leading to the two contacts ot' a suitable switch, W, whichin turn is connected with one pole of a battery, U, the other pole of which is suitably grounded. With this arrangement, when the gas is'to be lighted, the switch Wis turned to connect the upper coil, I, through the binding-post Q and wire T, with the battery. An earth-circuit is thus made from the battery through connecting-wire to switch W, through wire T, post Q, upper coil, I, wire I', contacts S and S', thence tothe ground, as described, and back to the battery. The upper electro-magnet being thus active, the armature O is raised, opening the valve N and permitting the gas to flow from the burner-tip, and is prevented from falling back by the engagement of the swinging dog P* with the shoulder O2, thus keeping the valve open.V The armature Oat the same time is drawn up to the fixed coreseetion M, when its valveN, or a projection thereon, strikes the holding-spring S, thereby raising the movable contact S', breaking the circuit, and producing a spark which ignites the gas. When the circuit is thus broken, however, the upper magnet becomes inactive, allowing the armature O to fall with the valve until checked by the dog Pf and the circuit is again closed. This operation is repeated, producing a succession of sparks, until the gas is ignited, when the switch W is turned to break the circuit. l

To extinguish the light, the circuit is closed by the switch through the lower coil and connections. The lower magnet, then becoming active, quickly raises the swinging armature I?3 into contact with the core-section I?, disengaging the dog P from the shoulder O2 on the armature O, allowing the same to fall by gravity, aided by the attraction of the lower mag+ net, and close the supply-regulating valve. The tubular shell C, in connection with the core-sections M P, really forms a continuous hollow or chambered core for both magnets,V and is made separate from'the core-sections only as a matter of convenience in manufacture. For the same reason it may be made of a different metal therefrom, it having no appreciable eiiect upon the magnets, owing to its thinness. By thus winding the coils upon a hollow core within which the valve-operating devices are Vlocated an extremely simple and compact burner is produced at a low cost..

Having thus fully described my invention, what I claim as new, and desire tovsecurc by Letters Patent, is v 1. The combination, with the sleeve having the upper and lower coresections, the electromagnetic coils surrounding the same, and the valve and its operating-armature, of a second armature pivoted to swing within the core, and a dog for engaging the valve-operating armature operated by the swinging armature, substantially as shown and described.

2.. The combination,with the pipe-coupling sleeve, the hollow shell, the anuularly-flanged disk on the upper end of the sleeve, having a central opening forming a valve-seat, and carrying the binding-posts, the electro-magnetic coils surrounding the sleeve, a valve closing the valve opening and provided with a stem extending down into the sleeve, and the valveoperating devices within the sleeve, of the cap upon the disk supporting the burner-tube, the

insulated fixed contact extending adjacent to the burner-tube, the lvertically-movable contact extending into the cap, and a supportingspring for said movable contact in the path of the said valve, substantially as set forth.

3. The combination, with the sleeve, the upper and lower core-sections, the electromagnetic coils surroundng said sleeve, the upward-opening valve, and the verticallymovable armature for operating it, of a second armature movable within the core and pro-
