Abstract: 24,987. Regester, F. A. Nov. 11. Fire-places; smoke-consuming; ovens; boilers; convertible coal and gas stoves.-Fire-places with down-draught grates of the kind described in Specification No. 13,598, A.D. 1904, are fitted with removable and renewable reverberatory fire-backs, air-supply arrangements, modified air-heating and ventilating fittings, and ovens adapted to be heated by flues, hot air, steam, or gas fittings. Waterheating and steam - generating fittings are also described, and the grates are shown fitted to a double pedestal stove with open fires adapted for heating air for ventilation. The invention consists principally in the combination, with the downdraught-producing flues r, Fig. I, described in the above-mentioned Specification, of an ash-pit m, forming a " regenerative " chamber for heating the air supply for combustion, and of one or more vertical channels n, o, through which the hot air ascends from the ash-pit. The air, leaving the apertures o, descends and mixes with the products of incomplete combustion, and is drawn through the fire by the draught in the flue r. There may be fitted a removable fire-brick j, which reverberates the heat back to the fire on the grate l. The firebrick is supported by shoulders t on the sides of the fire-place. A further supply of hot air passes through the passage u to the combustion products as they enter the flue r. By increasing the draught in the flues r sufficiently, for instance, by the use of a blower or the like, the draught in the air passages n, o may be reversed, air and smoke &c. passing downwards to the ash-pit m, and thence to the flues r. Fig. I<A> shows a similar grate in an air-heating open fire-place with an air-heating chamber m beneath the bottom block k of the fire-place. Air enters by the passages y, part entering the chamber m by the passage m<2>, and part passing through the oaffle-fitted chamber v and thence through pipes w to warm the room containing the stove, or other rooms. Fig. III<A> shows a modification in which a removable iron oven d<1>, with a combined fall door and dish rest i<1>, is fitted above the canopy of the tire-place. The air enters the chamber m through the curb i, and is delivered to the fire by a passage o at the back. It then mixes with the combustion products, and passes with them to downdraught-producing flues r, which are set behind the panelled or like sides of the fire-place so as to deliver the combustion products to the flues of the oven d'. A boiler may be fitted in place of, or in addition to, the oven d<1>. Baffles g<1>, g<2> and a damper s are fitted in the flues. The flue r on one side may be surrounded by a water-heater or steamgenerator, and on the other side by a chamber for heating the air supply, and pipes may be led from the steam-generator or from the hotair chamber for supplying steam or hot air to beat the oven d<1>. Fig. X shows a half-section, and Fig. IX a sectional plan, of a double air-heating stove with two grates, adapted to stand in the middle of a hospital ward or the like. The airheating chamber m in the ash-pit is formed by a plate b', and is connected to the space above the grate by the flues n, o. The combustion products, after leaving the down draught-producing flues r, pass down the flues a<2> to the main flue a<3>. Baffled air-heating chambers d<2>, Fig IX, are formed at the sides of the stove, and deliver air through the grids g<2>. Parts h<2>, h<3> are removable to facilitate the cleaning of the flues. A gas fire may be fitted in the fire-grates l; in this case the oven d<1>, Fig. III<A> , and its baffles are removed, and the outer casing plates f &c. of the oven flues form an internally-heated gas oven.
