GAS COOKING-STOVE.

.EBPECIFICATION forming part of Letters Patent No. 342,232, dated May 18 1886.

Application filed March 18,1885. Serial No. 159,299. (No model.) Patented in England October 51,1884, No, 13,084.

To aZZ whom it may concern.-

Be it known that we, JOHN SOMERVILLE, of Bankside, Southwark, Surrey county, England, mHl-VILLIAM Hoscoon YOUNG WEB- BER, of Amel Overhill Road, Forest Hill,

Surrey county, England,'have invented certain new and useful Improvements in Gas CookingStoves, of which the following is a full, clear, and exact description. This invention more particularly relates'to gas cooking-stoves which have a roasting or baking oven; and it consists in the construction and arrangement of parts, as will be here inafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 isa half elevation and section of a gas cooking-stove embodying our invention. Fig. 2 is a horizontal section of the same on the irregular line 00 x in Fig. 1, and Fig. 3 is a side elevation of the removable lining of the oven and part of the outer casing and reservoir with the boiling attachment removed.

The oven A is rectangular in plan, slightly higher than its width or length, and may be provided with the usual means of suspending viands for cooking. It is formed of a lining 3o which we make of inoxidizable metal-such as copperor of iron rendered inoxidizable on the surface by a protecting coating of enamel, tin, copper, &c., or the black oxide produced by what is known as the Bower- 5 Barff process. Thislining or-oven-chamber A is not attached to the frame-work of the stove in any way, but is readily removable for cleaning or other purposes. It slides into its place upon flanges f, formed upon the casing 0 k, and is supported against lateral movement by other flanges, f, which also act as baffles to prevent the products of combustion of the heating flames of the burners d from making their way round the outside of the lining in 5 the space h to the flue y. The products of combustion consequently enter holes a a in both sides of the lining at or near its bottom, and escape from the oven by an opening, 0, in the top near the front. The course of the draft is shown by the arrows in Figs. 1 and 2. There is a clear space, 71, round the lining, which serves as a hot-jacket. \Ve prefer to dispense with the heat absorbing packing with which the space is commonly filled; but we are not precluded from filling it wholly or in part with any suitable packing cemented or otherwise secured to the casing Or flanges, so as not to interfere with the free moving of the lining.

The front end of the lining or oven-chamber A is rabbeted in the front plate, and held in place by the door 1', and the bottom is closed by the sliding drippingpan 1), so that while cooking is going on the influx of air is as much as possible confined to the holes a a. The oven-heating burners d, which are preferably of the ordinary flat-flame illuminating type, are fixed upon the gas-supply tubes 0, which are hung to swivel or swing, as at c, either at the front or back. The number and power of these burners may be varied according to the size of the oven; but in any case they will projeet their flames, as shown, through holes in the outer casing of the stove corresponding to the holes a a in the lining, and will be swung into the position indicated by the dotted lines in Fig". 2 for lighting.

The flames will not enter the inside of the oven, except slightly, and will not therefore take up the area of the oven, but will radiate their heat freely into it, and also send the pro ducts of combustion as already described.

The waste products of combustion, after issuing from the oven at o, pass-over the top of it in the space a, Fig. 1, and travel to the outlet-flue y, underneath the boiler B, which is made to conform to the shape of the stove and oven, as shown, and has a large heating-surface in proportion to its capacity.

For heating the boiler when the oven is not used, there is a separate set of burners, m, protected bya perforated screen, 8. The boiler thus forms an integral part of the stove, and its cover Z is the bottom of the upper portion, 0, of the stove, in which are disposed the boiling and grilling burners g g. The boiler is filled through an opening in the cover, and is emptied by the cock 2.

To prevent too sharp a draft through a a, we may place the flue-outlet'y, which is controlled by a damper at a lower level than the bottom of the boiler.

To render the stove as convenient for use as possible, we place plateraeks on the sides, as at 'v v.

Ve prefer to use flat-flame illuminating burners for all purposes.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a gas cooking-stove, the combination, with the casing thereof, provided with inletapertures and an outlet, of a swiveled gassupply pipe on the outside of the casing, and

provided with burners constructed to register with the inlet-apertures in the casing, substantially as set forth.

2. The combination, with the outer casing, 70, having apertures in its lower edge and flanges f f on its inner sides, of the removable inner casing having openings a,in alignment with those of the outer casing, an outletopening, 0, and the swinging supply-tube 0, having burners (1, adapted to enter the chamher or space between the inner and outer apertures, substantially as set forth.
