LE ROY S. \VHITE, CF NATERBURY, CONNECTICUT, ASSIGNOR TO THE ELECTRIC APPLIANCE COMPANY, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 324,058, dated August 11, 1885. Application filed April 24, 1884. (No model.)

To all whom it may concern.-

Be it known that 1, LE ROY S. YVHLTE, of Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Apparatus for Turning On, Lighting, and Shutting Off Gas by Electricity, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates, principally, to that class of electric lighting and extinguishing device in which the shutting off of the gas is effected by a valve which closes automatically when free, and the opening of the valve to turn on the gas is efiected by an electro-magnet, and in which the sparking device for lighting the gas is operated by the opening of the valve. Examples of such devices may be found in my Patents No. 282,816, dated August 7, 1883, and No. 298,531, dated May 13, 188 1. In carrying out this invention I use some features which are shown and claimed in those patents; but instead of employing a permanent magnet for locking the valve open and unlocking it to let it close, as described in those patents, I employ according to my present improvement, in combination with the electromagnet coil and a core carrying a gasvalve and movable vertically in the coil for opening the valve, and serving by its upward move ment to also operate the sparking devices, an independent electro-magnet for unlocking the core and valve, and I lock the core in an elevated position, with the valve open, either by an armature actuated by the same magnet which opens the valve or by a spring.

The invention consists in novel combinations of parts, hereinafter particularly described, and pointed out in the claims.

Figure 1 in the drawings is an outside view, on a scale larger than the natural size, of an electric gas-burner embodying my invention. Fig. 2 is a central vertical section of the same. Fig. 3 is a horizontal section of the same in the plane indicated by the line :0 a; of Fig. 2. Fig. 4-is an eler atiompartly in section, of a portion of a burner and its appurtenances,illustrating a modification of my invention. Fig.5 is a horizontal section on the plane of the dotted lines y 3 Fig. 4.

Similar letters of reference indicate corresponding parts in the several figures.

A A A designate the metal case which forms a gas-chamber, and also constitutes the body of the burner and contains the electromagnet coil B, the core C of which is loose, and has at its lower end the gas-valve f. The upper contracted socket, A, of this case receives the buruertip and the principal armature D of the magnet, and the lower contracted socket or base, A is intended to screw onto the gas-pipe.

The coil B of the electro-magnet is wound upon a tube, B, of brass, which is secured firmly into or integral with the base A and which has tightly secured on it the heads B B of non-conductin g material, between which the coil is contained. 1n the bottom of this tube B is the valve-seatf, to which the conical valvefon the core C is fitted, and a short distance above the base A there are lateral openings f f in the said tube, through which the gas, when the valve is open, passes freely into the case, wherein it circulates around the coil B, and whence it has free access to the burner-tip. One end of the wire of the coil B is connected with an eye-wire or hook, 0, and the other end with an eye-wire or hook, d, the said eye-wires or hooks being inserted gastight into base A of the burner-case, but insu-" lated therefrom. The eye or hook 0 is to be connected by a wire, 0*, with the battery, (not here shown,) and the eye cl is connected by a wire, 01*, with the sparking device, as will be presently more fully described.

The core 0 has a broad head, C, around the upper part of which is a flange, 6, above which a small pin, m, works easily, but not loosely enough for the escape of gas through a hole in the top of the case. WVhen the core C is raised, by sending a current through the coil B, and the valve thereby opened, the flange e pushes up the pin m against the metal lever G, which carries the movable contact-point of the circuit-breaker, and so separates the said point, as shown in Figs. 1 and 2, from the fixed contact-point j, which is attached to a post, F, which is firmly secured on the top of the case, such separation producing the gasigniting spark. This post F is insulated from the case, and is connected by the wire (I and the hook or eye at with one end of the wire of the coil B.

The lever G works on screws 7t 7;, secured in r ing one or other button ofa double key, from which two wires lead to the burner-one for the main coil B and the other for the small the upper part of the case, but is not insu- 1 electro-magnet Ethe normal condition of the key being that which leaves both magnets in 1 open circuit. vided with a screw, 7, to adjust it for thefl WVhen the circuit is closed through the coil B,by pressing on the proper button of the key, the current is from the battery through and l c to coil, out at (I to F, throughj contact-points at all times except at the instant of sparking.

portion of the tube B which projects above as of cup shape,) which serves to support the armature a. horseshoe form. (See Fig. 3.) This armature has connected with it by small yoke-pieces 0 0, of brass, a second armature, 1', from the top of which projects a pin, it. This pin may ,j, and G to casing, and thence by the Q'ZIS-PlPG to the ground. The core 0 is then lifted, and the valve/"thereby opened. The armature 9' is attracted toward the core C, and the pin it there- Under the head 0 of the core, in the exam- 1 )le shown in Fi s. 2 and 5 there is fast on a 1 by brought under the thick part of the corehead 0, and caused to lock the valve open.

.j The lifting of the valve causes the flange e of the coil a broad metal flange, B (represented the core-head to raise the pin on against the 1 lever G, and cause the latter to break the con- ,small independent electro-maguet E and its 1 This magnet is represented of tact atjj and so produce the lighting-spark. The button of the key having been depressed only long enough or often enough to produce {the turning on and lighting, the key is left 3 free and the circuit open until it is desired to be brought by the movements of the armatures either to the position under the thick part of the head 0 ofthc core, as shown in Fig. 2, where it will holdup the core and lock the valvefopen, or to a position outside ofthe thick part of the head and under the flange c, where it will fail to support the said core and will unlock the valve, so that the valve is left free to close by gravitation. The movements of these armatures n r are so restricted by the room left for it between the cupped margin of the flange B and the poles of the magnet E that the armature a can move to the poles of 1D, and the armature r can approach the core U very much nearer than it is possible for a, and hence when there is a current through the coil B the armature r is drawn toward 0 near (llOllgll for the pin h to lock the valve open, and when there is a current through E the armature a is drawn toward the poles of the latter and made to move the pin h outward to a position to unlock the valve. it will be observed that the two armatures always move in unison, both being moved when the current is sent through either coil B or E, and that either coil puts them in a position to be acted upon by the other coil.

The wire 1) from one end of the coil of the elcctro-magnet 1) passes down inside of the case and outside of the coil B to an insulated eye-piece or hook, q, inserted tightly through the base of the case, and this eye-piece or hook is to be connected by a wire, .9, with one pole of the battery. (Not here shown.) The wire i from the other end of the said coil is connected with the metal flange B.

The apparatus thus constructed is operated by a single battery, one pole of which is coir nected with s and the other with 0*, and the closing of the circuit through one electro-magnet on the other is effected by means of one or other of two separate keys, or by pressturn off gas, when the other button of the key is depressed. The current now comes from the battery to s, thence through (I and p to the magnet E, thence through wire it to flange B, and through tube B to case, and thence by gas-pipe to ground. The armature n is then attracted toward the magnet E, and the armature 1', moving with it, carries the pin it out from under the thick part of the core'head O, and allows the core to drop by its own weight, and the valve to close.

In the modification illustrated by Figs. 4 and 5 the armature 1' is dispensed with, and the locking of the lifted core U with the valve open is effected by a spring, a, the lower part of which is secured to the base A of the case, and the upper end of which is connected with the armature a. The only other feature in which this modification differs from what is shown in Figs. 1, 2, 3 is in the form of the corehead 0, which here has a downwardly-turned flange, a. In this case all that the small independent electro-magnet does is to unlock the core, the locking being effected by the pin 7L 011 the armature a coming under the edge of the flange c, and the unlocking by the armature a withdrawing the pin it from under the flange 0. \Vhen the circuit is closed through the coil B, and the core is lifted to bring the lower edge of the flange 0 above the pn h, the armature n, being free, is moved by LL16 spring a to bring the pin it under the said flange, and locks the core up and the valve j open; but when the circuit is open on B and closed onE the attraction of the armature it moves it to carry the pin it from under 0, and unlocks the core and valve.

\Vhat I claim as myinvention, and desire to secure by Letters Patent, is-- 1. The combination, with a gasburnerhaving a case wherein is arranged an electromagnet coil, of a core movable vertically within the coil of the clectro-magnet, and carrying a valve for controlling the flow of gas to the burner-tip, sparking devices, and a connection through which the core operates upon them as it rises, to produce sparking, a locking device for holding the core elevated and the valve open, and a second electro-magnet for unlocking the lockin g device and allowing the core to fall to close the valve, substantially as herein described.

2. The combination, with a gas-burner having a case wherein is arranged an electromagnet coil, of a core movable vertically within the said coil, and carrying a gas-valve, and provided above the said coil with a head or laterally-extending flange, sparking devices, and a connection through which the core operates upon them as it rises to produce sparking, an independent electro-magnet arranged above the main electro'magnet, and a laterally-movable armature and a stop which serves to hold the core elevated and the valve open, and which,when attracted by the independent electro-maguet, will withdraw the stop from below the head of the core and allow the core to fall and close the valve, substantially as herein described.

3. The combination, with a gas-burner and a case wherein is arranged a main electromagnet coil, of a core movable vertically in the coil, and carrying a gas-valve, sparking devices, and a connection through which the core operates upon them in rising to produce sparking, an independent electromagnet, and two armatures connected together, so as to move simultaneously, and carrying a stop for lockin g the core in its elevated position, one of said armatures being arranged to be attracted by a current through the main electromagnet coil, and the other by a current through the independent electro-magnet, substantially as herein described.

4. The combination,with the burner-casing having a valve-seat at the bottom, the electromagnet composed of a tube, E, coil B, central movable core, 0, and armature D, all within the said case, the valve f at the lower end of the said core, and the broad core-head G on the otheriend of said core, of the electro-magnet E, arranged within the said casing above the first-named electro-magnet, the two connected armatures n and 1', placed on opposite sides of the said core (J, and the locking-pin h, attached to one of said armatures, all substantially as herein described.
