IMPROVEMENT lN SELF-FEEDING COOKING-STOVES.

Specification forming part of Letters Patent No. 129,379, dated July 16, 1872.

SPECIFICATION.

Be it known that I, GEORGE WEAVER, of Lockport, in the county of Niagara and State of New York, have invented certain Improve ments in Self-Feeding Base-Burning Cooking and Heating Stoves, of which the following is a specification:

My invention relates to a self-feedin g baseburning heating and cooking stove; and it consists principally in a novel arrangement of `diving-lines under the griddle-holes of a stove communicating with a centrally-located iirepot at the upper end and with smokepassages under the oven at the lower end.

Figure 1 is a plan or top View of my invention. Fig. 2 is a vertical section taken in the direction of the dotted line w, in Fig. l. Fig. 3 is an inverted view, showing the bottomplate removed.

A, Figs. 1 and 2, represents a coal-reservoir or feeder, communicating with the iire-pot B, as shown. This reservoir may be Ina-de quite high and small in diameter, if desired, but I prefer to construct it long and shallow, and with a part of the bottom inclined, as shown. The fire-pot B extends from the fire-space C to the ash-pit D, and between its walls and the outer case of the stove a tight air-space, F, Fig. 2V, is formed. The griddle-holes for cooking purposes are arranged" around the coalreservoir A, as shown in Fig. l, and directly under each of them a iiue, G, passes down through the air-space F to the smoke-passages H, Figs. 2 and 3, in' the base of the stove. The caloric current is thus conducted from the fire-pot directly under and against the bottom ofthe cooking utensils to the lues, and thence to the chimney, as indicated by the arrows in in Fig. 2. hampers I are arranged to slide over the iues G, thus shutting oli' the heat from any particular griddle-hole in the stove, or all but one.' A damper, J, is also provided at the rear of the lire-space U, which opens a passage over the oven to the pipe K, and a direct draught obtained when desired. From the passages H the products of combustion pass up the iiues L, at the rear of the oven O, in the usual manner. A damper, M, is located in the front wall of the oven7 which admits hot air to the latter from the space F, and dampers e e may be applied ifi the outer case of the stove to allow such heated air to pass into the room when desired for Warming purposes. l?, Fig. 2, is a deflector or distributor placed at the mouth of the coal-chamber A and extending some distance into the fire-pot. It is supported within the latter by two or more arms, a, or other suitable means, and its form is preferably that of a double cone, as represented in Fig. 2. This detlector operates to distribute the coal as it falls from the reservoir toward the {ire-pot on all sides, and since there is thus but a thin annular mass of coal on tire the combustion is very perfect and the heat obtained all economized by radiation from the Walls of the fire-pot. The grate b may be shaken through the door c, an opening being provided in the iirepot at the point g for the admission of the shaking-bar. It may be desirable also to locate a mica door, d, in

the front wall of the stove, opposite to which, at the point 7L in the iire-pot, grated openings are provided for the admission of light into the room. The passage R, Fig. 1, from this door to the fire-pot is Walled oft' i'rom the airspace F, as is also that from the door c, which latter opens into the same compartment. It will be seen that, by means of the peculiar arrangement of the lire-pot,coal-reservoir, and ues G in a cooking-stove,I obtain an effective and economical cooking apparatus and heater combined, possessing many advantages over stoves of the ordinary form. The lire-pot may be made six-sided or any other suitable shape. The ues G may be placed against the outer Wall of the stove, in which case they'would be uncovered by sliding the dampers I in.

Vhat I claim as my invention is-L The combination, in a base-burning cooking stove, of the diving-dues G, the centrally-located re-pot B and coalreservoir A, and the smoke-passages H L, under and in the rear of the oven O, arranged to operate substantially as set forth.
