GAS SUPPLY FOR AUXILIARY APPLIANCES Filed Nov. 5, 1948 INVENTOR We LTER KENNEDY ATTORNEY Patented Jan. 6, 1953 UNITED STATES PATENT '0 F Fl CE GAS sorrnr non AUXILIARY APPLIANCES Walter Kennedy, Clifiside Park, .1. Application November 5, 1-948, Seria1'No.'58,56-9 9 Claims. (o1. 126.3 9

This invention relates to gas stoves, range and the like. More particularly, the invention deals with a gas supply means for apparatus of this class to service an auxiliary appliance, such for example, as a broiler, oven or the like. Still more particularly, the. invention deals. with a gas supply means comprising movable parts coupled with a part of the range, so that the supply is normally concealed when not in use, and can be extended over the top of the stove or range 'tobe accessible for use.

The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed, and in which the sepa- 2 disposed outwardly of the wall ill for regulating the supply of gas to "the horizontal pipe 111..

rate parts are designated by suitable reference the -line 2-2 of Fig. l, and indicating the gas supply means in collapsed and concealed positions, in dot and dash lines.

In gas stoves or ranges; as conventionally con- 7 structed, no means has been provided to service an appliance used in conjunction therewith. 7 It a has been old to apply an auxiliary oven on top of a stove and heat the same. byone of the conventional top burners of the range. "It has also been A known to service a portable gas burner through;

the medium of a flexible tube or hose.

'Ihefpurpose of :my' invention is to provide a neans".for supplying gas so as to service an auxiliary appliance which canbe arranged upon the top of the stove or gas range, the means being normally concealed within the wall structure of the range and adapted to be extended in position to facilitate coupling with the auxiliary appliance, such as a broiler, oven or the like. I

In Fig. 1 of the drawing, I have diagrammatically outlined the upper portion of a gas stove or range .III, M representing par-tot the front wall, 12 the top wall and at 13 is shown a raised v and hodded back wall portion which projects Such raised walls as,

above the top wall It the wall l3 are commonly employed in modern stoves or ranges, At I4 I have shown the nor mal gas supply pipe which supplies gas to the upper burners of v the range, and with this pipe is coupled a valve l controlled by a knob-1'6 Coupled with the rear end portion of! the pipe H, is an elbow-shaped fitting 18 having a projection t8 seating upon a bracket support 28 suitably fixed to a rear wall portion 2| of the range.

The fitting i8 terminates at its upwardly ex tended end in a conical or tapered portion 22, below which is an outwardly extending collar 23 forming :a seat for a coil spring 2-4. .At is shown a tubular arm having a lowerconi'cal bore 215 fitting snugly on the conical portionfi; said end having an externally threaded portion 21 for reception of a sleeve nut 28 which acts upon the spring '24 to tensio-nally support the arm 25 in engagement with the fitting I18 while facilitating "rotation of the :arm. around the fitting.

Extending from the end portion 26' is a horizontal part 29 on the arm, which terminates at its end in a right angle extension 139 having a closed end wall, as clearly seen at 3|, in Fig. l of the drawing. The extension 30 is apertured, as. :seen at 32, to receive a nozzle 3:3 through which gas is discharged into a supply tube .34 of an auxiliary appliance, indicated in dot and dash lineszat in Fig. .1.

A mit- 343 is mounted on the nozzle to secure the-same to the end 30 of the arm, and also to secure a bracket .3] to the arm, as well. as. a cup 5.8. The cup 38 has a. circumferentieilly spaced air passages 39 which are controlled and regulated by a conventional apertured and ad= a'ustabrle sleeve =40 in controlling air supply to govern the gaseous mixture passed through the tube 34 to the auxiliary appliance 3-5,.

The lower end of the tube Q34 .is reduced in diameter, as seen at M, to iacili-tate insertion into the cup 38, the reduced portion joining the tube in a bevelled wall 42, which wall has .cir cumferentially 'spaced apertures 43, through which air is free to pass into the tube 34, preferably ata point adjacent the nozzle '33. It will appear from :a consideration of "Fig. 1, that the end of the tube 34 adjacent the bevel 42 fits snugly in the upper end portion of the cup 88. "The irontwall of the hood 13 has a large aperture 44 through which the arm 25,.together with the cup and the other parts attached to the arm, is free to swing from the dot-dash concealed position indicated in Fig. 2, to the projected position shown in full lines in Figs. '1 and 2.

Thebracket 31 is secured to the inner surface of a cover 45 considerably larger than the opening 44, and adapted to conceal this opening as well as everything rearwardly thereof, when the cover is in closed position, indicated in dot-dash lines in Fig. 2. The cover 45 also preferably has below the bracket 31, an indenture 46, note Fig. l, which forms a finger-grip facilitating outward swinging of the cover together with the arm 25.

In the normal use of the gas stove or range, the cover 45 will be in closed position and the arm 25 disposed within the rear hodded part iii of the range, thus the range can be fully and completely used for its normal purposes, without blocking any part of the surface thereof. Whenever it is desired to use an auxiliary appliance, such for example, as a broiler, of the type and kind disclosed in my prior application Ser. No, 787,239 of November 20, 1947, now Patent No. 2,572,870, all that is necessary, is to pull outwardly on the cover 45, which will swing the arm 25 into the full line position shown in Figs. 1 and 2, exposing the cup 38 for the reception of the tube 34 of the appliance 35. In other words, the appliance is simply placed downwardly on the top wall [2 of the range, the tube 34 being guided into the cup in this operation and the appliance can be Supported between front feet, one of which is indicated in dot and dash lines at 47 in Fig. 1 of the drawing and the rear end will be supported by the lower end portion M of the tube 34.

Assuming that the air shutter it has been adjusted for proper air supply, the knob l5 can then be moved into position to supply gas to the nozzle 33 to ignite the broiler for use. When the broiler has served its purpose, it can be lifted from the top of the range and the door or cover 35 moved into its closed position, as indicated in dot and dash lines in Fig. 2 of the drawing. The lower end of the tube 34 has adjacent and slightly above the nozzle 33, the usual venturi 34.
