Abstract: 8151. Cox, G. J. April 9. Gas cooking &c. stoves.-Relates to the oven, burners, cooking-utensil and other supports, and other parts of a cooking-stove which can be converted into a gas fire and may be used for drying and airing clothes. The principal chamber A has two oven doors G, H, the upper one carrying a rail G' forming part of the frame for the lower door. A hot-closet B, having a single door B', is arranged as shown. A set of annular gas burners C for boiling &c. are supported on cradles between the chamber A and utensil-supporting bars D having pins to enter holes in a front-plate W and notches to interlock with notches in a backplate W<a>. A swinging trivet y is arranged below the chamber A. The heated air and products of combustion leave the oven through an opening J and a flue K leading to a chamber E with vertical partitions e' and an uptake flue L. Fresh air for ventilation and combustion may enter the oven through a passage M, the end of which is protected by a hood M', or a filtering- receptacle, and when the stove is protected by an air jacket, the air enters the oven through perforations. The oven A is heated by a removable atmospheric gas burner F which may consist of a bent tube supported by screwed feet and the ends of vertical gas-supply tubes with gas-injector apertures for inducing an air supply. The side branches are perforated and many carry burner nipples. The supply of air to all the burners may be regulated by spring clips or adjustable sleeves. Instead of a bent tube, two separate detachable sections may be used, hooked on to projections on gas-supply branches having injector apertures and gas-supply regulating-screws. The annular burners C are similarly mounted. Grids or shelves n<6> are supported in the oven by adjustable sliding-pieces n' clamped in position on side standards N by pivoted trigger-bolts engaging apertures n<1> or pawls engaging teeth on the sides of the standards. Each shelf may carry a pivoted hook n<7> to prevent it from being accidentally drawn out too far. An inclined shallow dripping- tray at the bottom of the chamber A discharges its contents into a trough at the front. Removable atmospheric burners for boiling, baking, fermenting dough, warming dishes, broiling, or toasting in the oven consist of perforated tubes branching from tubes resting in brackets S' on the sides of the oven. These burners may have perforated deflecting-hoods secured to the burner tubes by thumb-screws and spaced from the burners by ribs. One of these deflectors may be supported by a grid and have extended sides with corrugations or narrow ribs. The burner tubes may support hanging straps which carry the dripping- pan and have perforations to receive the ends of the side rods of the food-supporting grids. When using the apparatus for warming apartments or for drying and airing clothes, the deflector hood and its burner tubes are arranged nearly vertical, so as to heat asbestos, fireclay, or other refractory material to incandescence. The burner tubes may project into passages in a block of refractory clay and asbestos. The refractory material may be placed in a light metal framing or it may be supported by a portable water boiler. A fireguard or clothes rails may be supported by hooks or eyes on the front of the frame.
