Total! whom t may concern.

Be it known that I, JOSEPH ANToNUccro, States, residing at Oakland, in the county of Alameda and State of California, haveinvente'd a` new and useful Gas-Burner. of' which the following is a specification in such full and clear termsas willenabl'e those skilled in the art to construct and use the same.

This invention relates to a combina-tion gas cock and gas burner used for heating purposes and an object ofthe invention i's Y to produce an efficient mixingdevice whereby the air and gas will be properly mixed at all times, even though the supply of gas .may be very much reduced.

It will be uuderstood'by those skilled in .the art that where a needlel valve is used to reduce the quantity of gas passing to the mixing chamber that the veloc1ty of flow -v `of the gas is so greatly retarded and interfered with that the mixingv is very ineffectually done. Therefore, with this invention means are provided whereby the nozzle which delivers the gas to the mixing chamber has a chamber of considerable size im mediately adjacent it, the regulation being accomplished by the valve vwhich does not interfere wit-h the opening from the nozzle into the mixing chamber.

Another object of the invention is to providemeans whereby the pilot light will have gas supplied to it prior to the supply of gas to the burner proper. 1

In the drawings in which the same numeral of. reference is applied to the same portion throughout the several views, Fig ure-1 is a vertical sectional view through the burner, mixing chamber and pilot light, Fig. 2 is a'plan view of the burner, mixing chamber and pilot light, Fig. 3 is a view in end elevation of the pilot light, gas valveV and burner, Fig. 4 is al vertical sectional View of a modilied form of the gas supply valve, the plane of section being chosen to illustrate the,l relative position of the two ports in said valve, Fig. 5 is a vertical sec' tional view of the gas valve transverse to the valve plug, one of: the ports therein being shown in full lines and the other in dotted lines, and Fig. 6 is a front view of said valve.l

The numeral 1 represents'the gas supply pipe to which the gas regulating valve 2 is secured in the usual manner. The gas regulating' valve has a small nozzle 3 and has external and internal threads at 4. Revolublewithin the valve is a frustoconical plug 5 having the handle 6 to rotate the same. A screw 7 holds this plug in its proper place in the Valve and the plug 5 is provided with a stop 8 to prevent it frombeing .turned more than a given amount, the fixed part of the valve having a stop 9 which thestop 8 strikes. This plug supplies the pilot light with gas and its handle is so placed as to. be

operated with the left hand. Between the plug 5 and the screw the .valve there is a than the plug 5 nozzle 16. This threaded portion of plug 11 slightly larger which supplies gas to the ther-ight.

The object of placing the valve plug handles in the mannerI shownl is to take advantage of an almost' universal habit of people. All right handed persons when undertaking to light a burner of this character will strike the match in the right hand and will reach out with the left hand to turn the gasonin the burner. This naturally brings `the left hand to the pilot light handle. The

next operation of the person is to throw the ma'tch away whereupon the right hand will be used, and in this instance the burner valve will be within convenient reach at once. It thus becomes almost a certainty that the proper valve will be opened rst.

Supported-by the valve casing is a mixing chamber 12, said mixing chamber having a conical portion 13 and having arms 13, which have an opening therein to receive the end of the valve casing. The mixing chamber is curved upwardly as shown at 14 and has a pan like top 18. u

Resting upon the top 18 is a shallower pan shaped member 19 having a flange extending over the edge of the member 18, lugs 2 0 spacing said member a short distance away from the member 18 and a short distance above the same.

The pilot light is supported on the nozzle 3 as indicated at 21 and it has a long nozzle 22, extending into proximity to the edge of the burner top 18. 'Screwed within. the valve is a gas nozzle 16, said gas nozzle havingan opening 17, which is of sufficient size to supply the given burner with the necessaryamount of gas.

It will be observed that between the valve supplying the burner with gas and the end of the nozzle where the opening 17 is placed,

tov

n plug has a screw 11 toho-ld f v1t 1n place and lts handle 11 is placed at there is a considerable chamber which is for the purpose of always retaining a supply of gas so that the gas flowingfro'm the nozzle. tip will always move therefrom at a. good velocity to be adequately mixed with the air in the mixing chamber whether at a high or low pressure; an eifect that is dificult to accomplish when the needle valve at the opening 17 is used.

In Figs. 4, 5 and 6 a valve is shown which accomplishes the objects of the two valves vshown in the preceding gures. In these figures the valve casing is indicated at 25, a threaded portion ofthe valve at 26 and the nozzle leading to the pilot light at 27. This valve is also threaded at 28 to receive a pipe 29.

The valve proper comprises a frustoconi- 'cal plug 30 held in place by means of a screw 31 and operated by means of a handle 32 at the left of the valve, the same as is used for the pilot light in the preceding figures. This valve plug has two ports therein, one

-25 at 33 and one at 34, said ports being so spaced apart and shaped as to supply the pilot light with gas prior to the time the burner is supplied withgas, note Fig. 5, in which gas is flowing fully to the pilot light.

`within the mixing chamber,

` my hand this 3 Further movement of thev valve'supplies the burner with gas, and when the burner is receiving a further 'supply of gas a furtherm'ovement of the valve will cut 0E the pilot light from the supply 'of gas altogether.

Having thus describedmy invention what I claim as new and desire to secure by Letters Patent of the United States is as follows.:

In-a gas burner, 'the combination of a shallow pan, a 'mixing chamber leading from the lower side of said pan, a smaller flanged pan loosely lit-ting into the rst pan to cause the mixed gasto be discharged therefrom in an annulus, a 'gas supply pipe, a cut off valve connected with the pipe and niixing chamber, and-a removable gas tip substantially as described. A

In testimony whereof I have hereunto s et .the presence of the two subscribed'witnesses.
