GAS COOKING STOVE AND RANGE.

SPECIFICATION forming part of Letters Patent No. 251,215, dated December 20, 188].

I Application lledMay28, 1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM W. GOODWIN, of Philadelphia, in the county of Philadelphia and State ofPennsylvani-a, have invented new and useful Improvements in Gas Cooking Stoves and Ranges, of which the following is a specitication.

The object ot' my improvements is to perfect gas cooking-stoves in respect to the utilization of the heat to the greatest possible extent, thereby economizing in the use of' gas as fuel, and also to construct such stovesin a manner to give the greatest facility and convenience for cooking operations.

The invention consists in a novel construction and arrangement of parts, as hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a front elevation of a gas-stove embodying my improvements. Fig. 2 is a vertical cross-section ot' the same on line xxot' Fig. 1. Fig. 3 is a vertical longitudinal section on line y y oI'Fig. 2. Fig.

` 4 is a vertical cross-section on line z z of Fig. 1.

The other figures are detail views.

Similar letters of reference, indicate corresponding parts.

The body of the stove is formed of plate a, forming the back wall, side plates b b', forming side walls, bottom plate, t, top plate, fw, and front plate, j', that is formed with an opening and tted with door h for the upper oven, and opening for giving access to the lower oven space. Near one end is a vertical divisionplate, c, forming a space, c', next to the side wall b', in which is secured a water-tank, B, that is accessible through an opening iu the top of the stove, and is provided with a pipe and cock,A u, at the front of the stove for drawing off the water. The tank B is heated by a burner, t, that is in connection with the main supply-pipe, and is supplied with air and gas combined, as hereinafter described.

The space between the side walls b c is divided by a horizontal plate, k, that has its front and back edges turned down to form iuclined flanges lt', between which and the front and back plates, f a, is a narrow space for the passage ofthe products of combustion.

Above the plate k is fitted a closed oven, hf. At the'back and sides of the oven space is left for passage of the heat to the space above the oven beneath plate w. The plate k being attached to the side walls b c, tubes r r are litted thereto, extending upwal d at the sides ot' the oven, for the heat to passthrough. Above the oven, and extending from rear wall, a, to near the front wall, is a horizontal plate, p, and in back et, above plate p, is the escape-llue m.

Beneath the plate 7s at the front extend the burner-pipes t' t', which are supplied by separate pipes t2 i3 from the main supply-pipe G.

The object of using two burner-pipes is to permit the use of illuminating-gas alone, or ot' a mixture of gas and air, according to the quality ofthe gas. l

t is the burner-pipe for pure gas, which is perforated at one side, so that the dame will shoot backward beneath plate lc.

'1I is the burner-pipe for air and gas,'perfo rated at opposite sides, and this pipe may have branches extending back beneath plate '/c, so that the heat shall be equally distributed beneath place lc. The pipe i is provided outside the stove with an air chamber and valve, for admission of air with the gas, preferably constructed as shown in larger size in Figs. 5 and 6. As shown, the outer end of pipe t' is dared, to form an air-chamber, n', and tted with a register-valve, n, through which the air enters to the desired amount, according to the adjustment of the valve. rlhe gas-supply pipe t2 enters the air-chamber through the center of valve n, where it terminates, and is fitted outside the air-chamber with a cock for regulating the supply.

The sides and back of the lower oven-space are 4iitted with radiating-plates e, and are also ribbed, as shown most clearly in Fig. 3, to support pans, gridirons, and other utensils for roasting and grilling purposes.

The back and side walls of the stove are litted with au innerjacket ot plates, p,and suitable non-conduct-ing material is packed in the space between the jacket and walls of the stove, so as to prevent radiation of heat. This construction thus saves heat that would otherwise be lost, and at the same time renders the stove better adapted for summer use.

The walls of the stove extend above the top plate, w, and the space thereby inclosed is covered by a plate, s, that has openings for receivingsauce-pans, Steamers, and other uten- IOO sils used in boiling and steaming, as shown in Figs. l to 4. Beneath these'openings are Bunsen burners s ofan y desired construction, supplied by separate pipes s2 from main pipe C. These pipes s2 are furnished with airchambers and register-valves n, as described, in connecltion with burners i.

The water-tank B, as shown, is'for keeping a supply of hot water for use. as desiredwithout circulation. When a circulation of hot wateris desired the stove will be tted with a suitable heater that is in connection with a boiler and the usual water supply. I prefer to use a heater shown in a separate application for Letters Patent, consisting of a closely-Wound water-coil Within two concentric cylinders and furnished with a Bunsen burner. I prefer to use separate burners for the water-heater, so that a supply of hot water can be kept up when the stove is not in use for cooking.

I am aware that it is not broadly new to use a mixture of air and gas in gas cookingstoves to increase the intensity of the Hame, and I therefore do not broadly claim such; but

What I do claim, and desire to secure by Letters Patent, is-

l. The gas-supply pipes t2 is, burner-pipes i if, and air-chamber n', provided with valve n in pipe 2, combined together in a gas cookingstove, substantially as shown and described, whereby air is admitted to the burner to permit either pure gas or a mixture of gas and air to be burned.

2. In a gas cooking-stove, the combination, with the oven 7L and the burners z' i', of the horizontal plate k, provided with inclined flanges and arranged between the said burners and oven, substantially as and for the purpose set forth.

3. In a gas cooking-stove, the combination, with the side walls b c, of the plate 7c, having inclined ilanges 7c', and the tubes r, arranged at the sides ot' the oven, substantially as and for the purpose set forth.

The above specification of my improvement in gas cooking stoves and ranges signed by me this 6th day of.' May, 1881.
