Specification of Letters Patent.

Patented Nov. 3, 1914.

Application filed October 7, 1810. Serial No. 585,771.

T 0 (ZZZ whom it may concern:

Be it known that I, HOWARD LYON, a citizen of the United States, and a resident of Gloucester City, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in- Gas- Fixtures, of which the following is a description.

My invention consists of an improved gas fixture, the individual burners of which are equipped with ignition filaments connected in parallel and adapted to be energized by a central battery inclosed within the fixture, said battery and filament circuits being closed or controlled by an electromagnet likewise carried by the fixture and adapted to be energized from a separate source of current in a circuit provided with control ling switches situated at a distance from the fixture.

My invention also comprises various details of construction hereinafter described and claimed.

Reference is hereby made to the accompanying drawing in which Figure 1 is a side elevation of my improved fixture, partly in section; Fig. 2 is an enlarged detail of the central base of the fixture with parts carried thereby and showing also the arrangement of the magnet controlling circuits; Fig. 3 is a side view taken at right angles to that. of Fig. 2, and Fig. 4 is a detail of the gas control.

The fixture illustrated comprises a central gas supply pipe 1 of ordinary form by which the fixture is supported. Upon the lower end of this pipe is threaded a cock 2 which forms a central base for the fixture and is provided with supporting plates a and b and a distributing outlet 0. Horizontal pipes 3 extend outwardly from the outlet 0 for supplying gas to the various burners. The fixture shown is of the two burner type but obviously a greater number of burners may be used. Each of the pipes has an individual gas controlling cock to. At right angles to the pipes 3 are rods 4: An ornamental brass shell 5 incloses the central base 2 and is supported by the pipes 3 which pass therethrough and by screws (not shown) threaded into the ends of the rods 4. The cock 2 has a valve operated by the sector plate 7 and controls the flow of gas through the pipe 1.

The plate 7) carried by the base 2 is provided with. an insulating block let secured thereto and upon this block and secured thereto by screws or binding posts 15 are a pair of contact springs 16 and 17. Conduct mg wires 18 run from the spring 16 t0 ignlters 19 mounted upon the canopies 20 of the gas burners. The igniters may be of any desired type, but I prefer to use the form fully disclosed in my application Serial No. 566308 filed June 11, 1910, and in which the current is passed through a very fine wire or filament S of platinum. alloy, the current being preferably of a strength sufficient to initiate catalytic action of the wire upon the gas and air mixture, but insufiicient of itself to heat the wire to the ignition temperature of the gas. Return wires 42 run from the igniters l9 and are grounded, upon one of the rods l by a screw 43. The wires 18 and 42 are preferably run through the spaces between the pipes 3 and ornamental shells 41-1. A conducting wire 21 runs from the binding post 15 of the spring 17 to a contact spring 24: which is held between insulating blocks 22 and 23 bolted to the lower end of the outlet 0. The spring 2 1 is bent to bring its free end into position to engage one pole 25 of the battery 26. This battery is preferably a single dry cell of which one electrode 25 is situated at its center and the other is the usual zinc container 27 The cell 26 is loose within a brass cup 28 with which the container 27 makes contact. The cup 28 may be removably engaged with the shell of the fixture in any suitable manner. As shown there are a plurality of pins 29 extending outward from the cup 28 and corresponding notches (not shown) are formed in the flanges 31 of the shell 5 which permit the passage of said pins. The cup is then rotated sufiiciently to allow the pins to rest upon the flanges as shown in Fig. 1.

The igniter circuits are normally open at the spring 16, but may be closed by the action of a controlling magnet 9 mounted on the plate a, This magnet has an armature 1O pivoted at 11 to the post 12 carried by the plate Z). An insulating block 32 is secured to the said armature and a spring plate 33 is carried by said block in such position as to contact with the springs 16 and 17 when the armature 10 is raised by its magnet asshown in Figs. 2 and 3. The

magnet 9 is energized by a battery 34 preferably situated away from the fixture and controlled by a switch or push button 35 located at any convenient point away from the fixture. One end of the magnet coil is grounded on the cock 2, one pole of the battery 34 being also grounded. The other end of said coil is connected with the opposite pole of the battery through wiring 36 and push button 35. The armature 10 when raised by its magnet opens the valv of the cock 2 by rotation of the plate 7 as shown in Fig. a. The said valve may be closed by a reverse movement of said plate 7 effected by the armature 37 of an electromagnet 38 which is mounted. on the plate a. The armature 37 is pivoted at 50 to a post 51 carried by the plate 6. The magnet 38' is energized from the battery 3% controlled by the switch or push button 52 located away from the fixture. One end of the magnet coil is grounded on the cock 2 and the other end is connected to the battery through wiring 53 and push button 52'. Each of the armatures 10 and 37 is provided with a depending draw rod 54 by which it may be operated independently of its controlling magnet.

The device is operated as follows: In order to light the burners, the individual cocks 40 ar first opened and may remain so at all times as the gas for the entire fixture is controlled by the cock 2. The push button is then pressed and an electric circuit thereby completed from the battery 3a through the magnet 9'. The armature 10 is raised by its magnet into the position shown in Fig. 2 whereby the valve of the gas controlling cock 2 is opened and the igniter circuits are closed. An electric current thereupon flows from the battery 26 through its electrode 25, spring 2 wire 21, springs 17, 33 and 16 thence in multiple through the several igniters, thence by return wires or the metal of the fixture to the battery. The current through each igniter causes the gas to quickly ignite, and the push button 35 is then released, whereupon gravity causes the armature 10 to drop which moves the spring 33 away from the springs 16 and 17 and opens the igniter circuits. In order to extinguish the burners, the push button 52 is pressed and an electric circuit thereby com pleted from the battery 3 1- through the magnet 3'8. The armature 37 is raised by its magnet into the position shown in the lower part oi Fig. 4:, whereby the valve of the gas controlling cock 2 is closed. This is effected instantly and the push button 52 may be at once released.

Having now described my invention, what I claim is:

1. In a gas fixture, a supply pipe, a base secured thereto, a gas controlling valve, an electro-magnet mounted on said base and having an armature controlling the movement of said valve, means for energizing said magnet, a burner, a normally open electric circuit comprising a source of current independent of said magnet energizing means and electrical ignition means adjacent said burner, and a contact actuated by said armature for closing said circuit.
