To allnwho'm it may] concern." 1 A [Be it known that I, ERNEST,WOOLLETT, a citizen of the UnitedStates, residing at Chicago, .State or IllinoiS, have invented certain new and, useful Improvements in Valves or the like, of whichithefollowing is a description. 1

construction comprising a pilot light which slighted and then used to lightthe burner, it being. impossible for the gas to flow to location on the stove, as shown it isarranged at one corner-and thepilot arranged to be turned: through an opening or slot 33 to The preferred construction of valve com-v prisesa casing 9 provided with an inlet from the supply pipe 8 and an. outlet 10,

the passage of gas through the casing being controlledby a suitable valve member 11 or its equivalent. The valve member is. provided with supply pipe 8 and with-a port opening 13 to the outletlO. In the preferred construction the valve member is extended as at 1A as will be more fully explained hereafter.

The valve member may be arranged and e PatentedDec.1,1914. Application fi1edMay 15,1909. Serial No. 496,273 1 i the irner until the. .pilot is in operative 1 i 0 be placed in any suitable a chamber 12 open to the secured in position in any suitable way, as

shownthecasing is slightly tapered as is also the valve member, the valve member beingretainedin position by means of a 15 and nut .16. Any equivalent means may be employed for the purpose. The gas through the supply pipe passes through; he'chamber '12 in the valvemember 9 through the port 13 into theburner inlet pipe 6 when the valve member is rota ted so that the port 13 registers with the.

casing outlet 10 (see Fig. 8). As shown the port-B and: the casing outlet 10 are preferably, constructed inthe form of slits so that the gas 1cannotfflow into the pipe 6 and thence into the burner until the lighter-is in operative position. 1. The slits permit the valve to be opened wide almost instantaneously instead of gradually. Any suitable means'may be. employed for limiting the movement of the valve members, as shown the casing is;cut away as at 17 (Fig. 5) and a pin 18 arrangedon the valve member, the part cut out" substantially representing the travel of the valve.

As before mentionedthe valve member is extended as at 14 to form a casing for what may be termed an auxiliary. valve member or pilot valve member 19, The chamber 12 11 isextended asat 22 19 which is pro- Zitothe chamthe port '23 .be-

in the valve member to the pilot'valve member vided with a port opening her 24: in the valve member,

ing arranged to register with the opening 22 when the pilot 25 is turned down to the position shown in Fig. 3. 7 The auxiliary valve member may be of'any suitable shape and design, as shown it is preferably tapered and arranged to fit in its casing, a suitable Washer 20 and screw for the purpose being provided to retain-the same in position. The chamber 24 in the auxiliary valve member 19 is connected to the pilotmember 25 there being an opening 26 through the pilot member as shown. The pilot'member may be of any suitable form or size, the same preferably comprising a tube ad pted o fit and be secured in the tended part 27 of the auxiliary valve member. Any suitable means may be employed for limiting the movement of the auxiliar i valve member, as shown the part 14'. is cut on the valve member and adapted to cooperate with the cut out portion and limit the movement of the valve. When the pilot is in the position shown in Figs. 1, 2, 5 and 6, the auxiliary valve. member is in such a position that the port opening 23 does not register with the opening 22 in' the other valve member so that no gas is V admitted to the pilot. In the preferred con- 30 struction it is desired that the main valve member 11 close the outlet 10 in the casing when the pilot is closed and that themain valve member be locked against rotation except when the pilot is turned down. -To lock the main valve in its closed position when the pilot is turned up I preferably provide a stop or flange 30 on the valve casing arranged to cooperate with the extension 31 on the pilot valve member 19 (see Figs. 5,6 and 7). casing is preferably extended around the casing some little distance as shown in Fig.

7, so that thepilot member can not be turned to the position shown in Figs. '5 and 6 unit less the valve'member isturned' so that the extension 31 on' the pilot Will not interfere with the flange 30 on 'thej'c'asing. The extension on the pilot may be extended as shown at to form a handle for controlling 56 the movement of the pilot.

' Assuming that the gas in the stove oven is 'tobe turned on and it is desired to light the burner, the gas being turned oil" the pilot is in a position indicated in Figs. 1, 2,

-" 5 and 6. To light the gas the pilot is turned down to the position indicated by the dotted v lines in Fig. 4 which opens the pilot valve so that a match may be applied to the pilot and the same be thereby lighted. The pilot is i 60 then turned in to the oven through the opening 33 so that it takes substantially the positions shown in Figs. 3 and 4 'or within lighting distance of the burner. This opens the mainfvalve sothat gas is admitted through the inlet pipe 6 and mixer 7 Where it is im-' beinglighted provided 21 or their equivalentsout as at 28 and a suitable pin 29 arranged heating The flange 30 on the.

mediatelj" lighted by the pilot light. In

this. construction both valves being controlled directly by the movement of the pilot, in bringing it down and swinging it inward there is no possibility oftheburner not the pilot is lighted and there can be no accumulationof gas in the oven, as for example, inthe case where the two valves are independentand the main valve opened and then at some later timethe 7 pilot turned to the burner. In this example mentioned the'mixture of gas 'and'air in the oven mightbe-sullicient or such asto form an explosive mixture which would'be-set off by the pilot light." It'might be noted that thepilot might be provided with a small Valve so that the pilot mightbe'turned off after the burner has been lighted but this.

constructionhowever is not necessary and is preferably omitted. It might also be mentioned that in cases where gas is used for an oven in which the gas isturned on fora certain length oftime heating a plate or the equivalent of heat storing material and then the gas turned oil and the oven shut up,my devicemight be very aptly applied thereto in which case it mightbe passed through the door opening or the equivalent by w-hich air is admitted for the burner While the heat'is being stored; In this case it would be impossible to close the door. or opening, thereby closing the: oven, if the pilotpassed therethrough without turning off the gas thereby avoiding the danger of closing the opening and having thegas burner extinguished for lack of air. This is merely mentioned 'as a use'of the'device when applied to" another style of'oven other than that shown. As before mentioned it might also be found verysatisfactory when used on a water heater; V Having thus describedmy invention it is obvious that various immaterial Inodific'ation's maybe made in the form, arrangement. and combination of parts without departing from the spirit of my invention; Hence I do not Wish to be understod as limiting myself to the exact construction, arrangement, combination"of parts oruses mentioned,shown or described.
