' a mammals rnnivun hrrnrienmji Be it known that l, GEORGE ELf PIcKUP, a citizenof the UnitedStates,-residing at Newark, in the county of Licking and State of Ohio, have invented certain'new and use ful Improvements in tlombined Gas. Burn ers and Lighters; of which the following isv 14 hasa plurality of discharge orificeslfi a specification.

Thls ve (commonly known as afs'imlnering burner) andlighting burner. a y

One of the objects of the invention is to provide a novel and improved controlling valve means, and av special object isto produce a valveby which a restricted flow of gas to a lighting burner is permitted at all times to maintain apiIot-light burning; by

which the pressure orflow of gas to such pilot-light may be. increased so as to flash tongues of flame from the pilot-light a sufiiv cient distance to light adjacent burners; and

by which the flow of gas to the simmering burner maybe completely controlled.

Another object is to provide a' combined simmering burner headand lighting burner head of. novel and improved construction.

The invention also refersto the details ofconstruetion whichwill be morefully point ed out in the following description;

In the accompanying drawings;

pilot-and-flashlight burner head 14: is a positioned axially within the burner head 10 and is connected thereto byiwebs 15. Pref-b 7 erably the burner head i 10, supply conduit -11;flange 13, pilot-and-flashlight burner head "14 and connecting webs '15 are formed in an integral casting. Thepilot-light head i (Fig. 7 inits sides corresponding in number and position to the main burners of'the stove. It will be; understood that in the embodiment of theinverition hereinshown, 1

the simmering burner, headjlO andpilot light head are intended to be positioned cenetrally between 'four main burners of the stove,jthe dischargeorifices'ldofithe pilotlight head being positioned approximately 1 apart aroundia circle sothateach of said orifices is arranged to direct a flamefto- =ward one of the four main .stove burners.-

In the flange; 13 are provided holes 17 re I istering with the orifices 16 :and throng which the tongues of ame when extended from said orifices pass ;into association wlth the main stove burners for lighting the lat ter. The burner head 10 preferably has one or more orifices 18- (Fig. 7) inlitstinner side i3 between the horizontal plane :of its main orifices l2 and that of thepilot-light orifices r 16, for the purpose of insuringithe lighting of the main burnerhead by carrying rip? the dame from the pilot-'light-head. he pilot-lighthead pipe *or conductor 19' which is in this n- W is supplied gasby a pipe '11.

The opposite end of themam pipe enlarged to provide an .alrninlet or mix ing bowl 20.0n the end of whichis mounted a shutter valve 21 ofsuitable construction,

which is arranged: to be moved by a fingerpiece 24., The admissionof air to thepipe I Y ll' maythus beregulated beneath the mam pipe ll for, the greater part of'its length, butthe inletend of-said pipe 19 is laterally bent to position the end for atftachrnent to: one out the outlets oftheggas controlling valve. In t the present instance The supply pipe 19 for the 19 the main pipe 11 has alaterally extending curved guard flange which overlies the bent end of the smaller pipe 19, the latter "being, secured to said'fiange by a'suitable clamp 26.

form herein disc osed'comprises a body having a verticalbore 31 therethrough in which fits a coniqal valve member or plug '32 i having an operatinghandle' 33 at its upper end, saidplug being yieldably drawn downwardly to hold it tight in said bore by means ofa coiled compression spring 34 surrounding a stud at the lower end of the plug and exerting its force against the plug on the one hand and thebody on the other.

The "body is providedwith an inlet nipple .35 andtwo outlet nipples 36 and 37, the mlet nipple being adapted for attachment to a gas supply pipe (not shown). The passages 38, 39,- 40, within said. nipples all communicate at their inner ends with the bore 31 The valve' plug 32 is provided with trans- .verse ports 41 and 42 theret-hrough, which angularly disposed'and'so arranged that by tuming the plugto different positions the inlet passage 'in the body may be placed mcommunicatlon through said 'ports with either one of the outlet passages singly or with both of such outlet passages at the same I time. Rotation of the valve plug 32 is limited .to a quarter-turn by suitable means which in the present instance comprises a pin 43 fixedto and projecting from the valve plug and arranged to abut against opposed shoulders 44formed by a notch in the upper end of the body.

The body is also 'provided witha by-passage 45' leading from the inlet passage 38 to the outletipassage 39:, said by passage perinitting a constant though small, supply of .gas to the pilot light for'maintaimng the latter lighted at all times. The amountor rate OfflOW of the gas through the by-passage may be controlled by suitable valve means herein shown as in the form of a I I screw 46 (Fig. 6) threaded in a socket 47 7 surrounds said pipe and engages the flared 7 main gas pipe 11 is provided with individual a valve means for controlling the flow of gas,

end thereof, said gland being threaded upon.

the nipple- 36 whereby a gas-tight joint is provided. x a

The outlet nipple 37 which-supplies the said valve means in the present instance comprising a cap 49 threadedonto said nipple and provided acentral aperture 50 Thecontrollin valve they preferred (Fig. 3) which is arranged to cooperate with a conical valve member 51 carried by the nipple 37. In the present instance, this va ve member is integral with the nipple, the latter having ports 52 atthe sides of said valve member leading from the passage within. The cap 49 and nipple project into the air inlet or mixin bowl 20 through a central opening in the utter valve 21.

The operation of the device is as follows: The normalposition of the valve is-that shown in Figs. 1 and 3, wherein the ports 1n the valve plug are out of register with'the inlet and the two outlets of the body. To

open the valve the handle 33 is swung to the left, as seen in Fig. 1, which rotates the valve plug in a clockwise direction as viewed in Figs. 3, 4 and 5. During such rotation the port 41 in the plug is first brought nto position (as shown'in Fig. 4) to establish communication between the inlet 38 and the outlet 39. This places the full pressure of the gas u on the pilot light and causes the tongues o? flame from the discharge orifices 16 to extend themselves into proximity tothe main burners of the stove so that any one of the said main burners may, if desired, be lighted by merely turning on its controlling valve.

Continued rotation of. the valve plug brings the port 42 into position (as shown in Fig. 5) to connect the inlet passage 38 with the outlet passage 40 which supplies the simmering burner, so that gas Wlll flow to the latter.

' In .a position of the plug intermediate those shown in Figs. 4 and 5, both of the ports 41' and 42 in the plug will simultaneously register or partia y register with the inlet passage 38 and with both of the outlet passages 39 and 40. In this latter position, the full gas pressure is supplied to the p1lot 2 light to project the tongues offlame and at the same time gas is allowed to fiow to the simmering burner head. The latter Wlll then be lighted from the flames of the p1lot light, the auxiliary orifices 18 on the nner side of the burner head facilitating or insur ng the transmission of flame from the p1lot light discharge orifice to the top orifices of the burnerhead. In this intermediate position of the valve plug 32, it will be seen that the simmering burner and all of the mam top burners of the stove may be lighted at once, providing the valves for the aforesaid main top burners are 0 ened.

By further turning .t e valve plug to the limit allowed by the in 43, the port 41 w1ll be carried out of register with the passages 38 and 39 and the port 42 will be placed in complete register with the passages 38 and 40. Gas under full .pressure will then be supplied to the simmering burner head, and the pilot light. head will then be supplied withonly a small amount of gas which flows through the by-passage so that only small or short tongues offlame are maintained at the pilot light head.

It will be noted that all of the functions 'above enumerated are accomplished by simply giving the valve handle 33' a quarter turn which is the usual amount of movement ture and Without the addition or complication of parts.

While l[ have herein shown and described the preferred embodiment of my invention .in considerable detail, I recognize that the essential features of'my invention may be made use of without the employment of the specific details herein disclosed.
