gas which flows through the fitting to the burners. Each burner is equipped with terminals g, g, of a lighting circuit, G, said lighting circuit including batteries, h, and a spark coil, h and a switch mechanism indicated in its entirety by the reference char- This switch mechanism includes two contacts, 2', 2", shown more clearly in Figs. 7 and 8 and the moving contact 9'. said moving contact being under the control of 7 Each lamp, A or B, is of ordinary construction, the same being provided with ventilating openings in a hood, a, a refiector, Z), at the rear of the lamp and a glass pane, b, at the front of the lamp, but the detailed construction of the lamp may be varied within wide limits, and according to the style or type of lamp used in the light circuit.

WVhen the system is used in conjunction with the head lights on an automobile, the

lamps should be provided with reflectors,

but these reflectors are'not necessary ordinarily when using the light system in conjunction with the side or tail lights of automobiles.

It is preferred to employ a burner, C, of the form illustrated more particularly in Figs. 8 and 4. As shown, the burner comprises a tube adapted to be secured upon a nipple, 0, which is attached to the base of the lamp in a manner to communicate with one of the two branch pipes, (Z or (la. The burner tube is composed of metal in order to serve as an electrical conductor as well as a gas conduit, such tube being provided at its upper part with a. burner tip, C. Or

dinarily acetylene gas is employed for lighting the headlights of an automobile, and the tip shown in Figs. 3 and 4 is provided with two orifices or gas outlets, 0, whereby gas will issue in jets to impinge against each other in a well known manner.

One lighting terminal, as g, is rigidly fastened in any suitable way to the tube of burner, C, in a manner to'be supported mechanically by said burner tube and to be in electrical contact therewith. The other terminal, g, is attached rigidly to a sleeve, 9 which is fitted on the burner tube and is insulatedelectrically therefrom, at 9 With this sleeve, 9 engages a spring contact, 9,

the latter having a bent lower end, is, which is insulated at 76 from the base of the lamp, such insulated contact being fastened to the contact being fastened in position by a binding post Z The terminals, 9, g, of the lighting circuit associated with each burner are positioned to lie close to the gas jets issuing from the orifices of tip, 0, whereby an electrical spark which jumps from one terminal to the other will operate to ignite thegas and produce the required light. As shown in the diagram, Fig, 1, a conductor, m, of lighting circuit, G, leads from'battery, h, to binding post, it, of lamp, A, so that the current will pass through contact, 9 sleeve, 9 and terminals, g, the spark jumping across to the other terminals, 9, and the current passing through the tube or burner, C, to contact, Z, and binding post, Z From binding post, Z runs a conductor, m, which is shown as extending to a binding post, Z of lamp, C, so that the current will flow through contact Z, the tube or burner, G, positioned in lamp, B, thence through terminal, 9, across to terminal, 9, thence through sleeve, 9 contact g and binding post, 7& of said lamp, 3. From the binding post, Z0 of lamp, B, runs a conductor, m which is shown as extending to switch contact, a". Conductor, m, leads from the battery to spark coil, it, and thence to the other switch contact, 73, whereby the circuit will be completed when the moving switch contact, j, bridges the space between switch contact, 6, i. The tank or generator, D, may be ofany suitable character. If acetylene gas is to be employed as the lighting medium I provide a generator of one well known form or another, but it is not intended to limit the invention to the employment of an acetylene gas generator, for the reason that any other type of generator may be used and I may, also, employ a tank for holding gas under pressure. From the tank or generator, D, extends a pipe, cl, the same being connected with a fitting, E.

In one form of the invention I employ fitting adapted to be attached to the dash board of an automobile, but it is not desired to limit the invention to use in connection with this particular type of-fitting, for the reason that other constructions may be emplayed for controlling the flow of gas from the generator or tank to the burners. As shown, fitting, E, comprises two horizontal members or legs, 6, c, and a vertical member or leg, 6 said vertical member connecting the horizontal members. The horizontal members are provided with collars, e and with nuts, 6 whereby members, 6, c, are adapted to be inserted through apertures of the dashboard, 0, so that collars, c and mate, c will cooperatewith the dash board tin . said valve seat accommodating n fi le valve,

E, .Whichpasses through the stuifing box. Said needle valve is adapted tov be adjusted for cutting off the flow' oii gaslth'rough the fitting, or for establishing the flow of gas from-the generator to pipe, cl, the latterbev ing attached to member, 6', ot the fitting, whereby gas will flow through branches, 0?, d to the burners within lamps, A.

Valve, E, is-shown as extending a suitable distance above the vertical member of the fitting, said valve'having a square or polygonal extremity, 9. Key or wrench F, is provided with a square; or polygonal aperture, for the-purposeof engaging withthe correspondingly shaped end, Q, of whereby the key or wrench is adapted tov be placed in .-po"s-i tive position upon the valve for the purpose: of opening cl i g i i or wrench may be readily disconnected from the valve in order that persons other than thy; chaufieur may not tamper with-said va ve.

each lamp carries the electric lighting terminals in operative relation to the gas outlet, and that said burner cooperates with two circuit contacts which are positioned within the lamp. Said burner may easily be removed from the lamp without disturbing the circuit contacts, whereby a wornout or clogged burner may be dismounted and a fresh burner substituted therefor without requiring'any special skill on the part of the operator. 7

In describing one embodiment of'the invention the lamps and burners are shown as included in series'in the electric circuit, that is to say, the current passes between the terminals ofone burner and thence to the terminals of the next burner, but it is not desired to limit the invention to this specific organization of the circuit to the burners thereinfor the reason that the burners may be supplied with electric energy separately.

.I-Iaving thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In a device of the class described, the combination of a casing provided with a duct, a valve having a threaded stem cooperating with said duct for the purpose of allowing or precluding the passage of material through said duct, an electric circuit 1 having a pair of spaced contacts positioned adjacent the valve stem, circuit closing means positioned adjacent the spaced contacts and mounted on the valve stem, a tension member normally retaining the circuit closing means out of engagement with the contacts, and valve operating means detachably mounted on the valve stem, and adapted for engagement with the circuit closing means, whereby the actuation of the valve operating means, operates the valve to allow the passage of material through the duct, and simultaneously brings the circuit closing mechanism into engagement with the spaced contacts, such valve operating means being thereafter adapted to be removed from the valve stem whereupon the tension memher is adapted to return the circuit closing means to its initial position.
