burners, and the objects or my invention are to provide an improved valve mechanism in-- terposed between the gas supply tank or gasometer and the lamp, by means oi which the gas will be supplied to the clamp at a proper uniform pressure regardlessot' the pressure contained in the gas tank or ometer, and to produce certain improve ments in details of construction and or will be more full pointed out hereinafter. These objects l accomplishin the manner illustrated in the accompanying drawing, in which:

Figure l is a side elevation of my device, Fig. 2 is a centrlil vertical section of the same, Fig. 3 is a view in elevation at right angles-with that shown in Fig. l, and, 4 is an outline view of the device showing its relationto the gas tank and the lump.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention, 1 employ a valve casing in the form of an oblong hrucltet body 1, which has cast therewith, pro ectmg lugs 2 to facilitate the attachment of the device to an automobile dash-board or other part of an automobile. Although the device shown in the drawing, is illustrated with the attaching flanges at the lower side of the valve casing body, it is obvious that this body may be supported at right angles to the position shown or in any other desired position. In constructing the valve casing or bracket body, I form the same with two arms or tubular projections which are indicated respectively at 3 and l, each of said arms or tubular-projections being externally threaded and formed with a central bore, these bores being indicated at 5 and 6 respectively, and leading from the inner end of the bore 5 is one arm of an angular and the restraining; arm oi e inner sud oi a hollow (led proy-ction 7 near the bus-c i. "the, upper end of the passage at I. junction with the bore as shown, formed. "with u. luring mouth to provide a needlepoint valve seat 5. From the bore or hollow at a point above the valve seat 5" leads through the body 1 a pas S, the remaining end of which comend of the bore (3 and as pre :ribed for the passage 5, is formed at it junction with said bore 6 with Z needle-point valve seat R. 'lhelower end portion of the bore 6 above the valve seat 8 has lending therefrom, short Literally cxtcnding puss-age S) which leads into the inner end of a hollow externally threaded valve casing irojection l0.

ll represents a iuiedle-ooint cutoff valve, the vertical portion of which passes through a packing not 12 carried on the projection 3, said vertical valve member being threaded, show), to a point near its lower end. and

muuicz tes with the inner said threaded portion. engaging the internal threads of the projection 3. Below the threaded portion ol the valve ll, said valve presents a. slightly reduced circumference andds provided with a terminal valve point 11, which is adopted to seat in the mouth 5 of the passage 5. The upper end of the valve member ll is provided with a. suitable handle 11". l likewise provide the internull Y threaded projection 4 with a threaded nee le point regulating valve 1i, which engages the internal threads of said projec tion 4 and which has its inner terminal end portion formed with. a valve point 14 adapted to engage the seat 8 The upper portion of the valve i l passes through a packing nut 15 let and has its head on the outer side of said aching nut squared as indicated at 1 t vl ith the outer end of the lateral projec-- convenient frame port an automobile.

The pipe or'tubc it? leading the tubular plOlCttlOll 7, connects with storage mounted on the projection,

tank 18 which may be of the type ordinarily employed for storing acetylene gas for use in automobile lamps or which may be the gasometer of an acetylene gas generator. The pipe 17 leads as indicated in Fig. l of the drawing, to a gas burning lamp it) and it is obvious that branch pipes or conductors is at once ,charged from the burners in the lamps, thus preventing proper ignition of the gas at the lamp burner, particularly Where the electric spark is employed for producing such ignition. This ditliculty arises fromthe fact principally that the operator at the cutoff being located at a distance from the lamp, is unable to observe the height or character of the flame produced in the lamp and is therefore unable to properly regulate the same. By my construction it,will be seen that by first turning or setting the regulating valve 14, so that the desired volume of gas only can pass from the passage 8 into the passage 9, the cut-off valve 11 may be opened to any desired extent without danger of admitting too great a volume of pressure of gas to the conducting pipe 17. In this connection, it will be understood that the acetylene gas in a storage tank such as is used ordinarily in automobile lighting, contains gas under such high pressure as to prevent its proper ignition without reduction in pressure.

What I claim is:

In a pressure controlling valve for automobile lamps, the combination with a valve casing body, having four externally threaded extensions thereon, there being a port exdending between two of said extensions, a pair of separated valve seats located in said portxa cut oft valve threaded into another of said extensions and engaging one 01 said valve seats, a packing nut threaded upon said extension, at controlling handle carried by said valve and extending through said packing nut, a regulating valve threaded into the remaining one of said extensions, and a packing nut through which said regulating valve extends, said packing nut being threaded upon the remaining one of said extensions, both the regulating valve and the cut-off valve being'accessible and controllable from the exterior of the valve casing. i

In' testimony whereof I atlix my signature in presence of two witnesses.
