This is a gas stove, where the oven has thick walls of a non-conducting material. The oven is heated, for a short time only, the gas flame being cut off when the oven has reached the desired temperature. At the left is an attachment where rapid cooking may be accomplished when desired, and there is a device at (1) with the same principle as the fireless cooker, or the tea “cosey.” This cover is dropped over the kettle when the boiling point is reached, the flame is turned out, and the heat in the water finishes the process. There is no good reason why stoves embodying
this same principle should not be used with kerosene, and with the electric current. Improved stoves of this type will be constructed, and certainly will tend toward great economy of fuel.
One method of saving fuel is by the use of a steam cooker, which consists of a series of compartments, one above another, containing several kinds of food, all to be cooked over the same burner, either gas or kerosene, or on one section of the top of the coal range when space is being used for the wash boiler or irons.
It requires intelligence to use such devices, and those who lack it cling obstinately to hot fires and violent cooking.
The coal range.—Progress is slow, and the coal range will not be abolished at present. Figure 18 is an example of a good range as easy to manage as possible. The coal box at (1) has a lining that prevents the iron from burning out. The air enters at (2) and passes out at (3), when the fire is first made. When it is necessary to heat the oven, a damper is closed at (4), and the heated air then passes around the oven in the direction of the arrows. The coal is put in at (5) and the ashes shaken down at (6). Larger ranges, resting upon the floor, have a “dump” for the ashes directly into the ash box in the cellar, and some makes have a device for operating this with the foot. The coal stove involves the
labor of bringing in coal and taking out ashes, and space must be given to the coal bin and ash pit. A range of this size would serve for a family of five or six. It requires from 2 to 3 hods per day. A hood should be placed above a large range, whether coal or gas.
