The ironing-machine, or, as it is often called, the mangle, is another device for making laundry work easier. It may successfully take the place of the hand iron for a larger part of the family ironing. There are two types of ironing-machines on the market: (1) cold-roll ironing-machines, in which the rollers between which the garment passes are made of wood and are unheated, depending on their weight and pressure to remove wrinkles; (2) hot-roll ironing-machines, in which one roll is cold and is covered with a blanket and cloth, just as for an ironing-board, and the other roll or concave plate is made of smooth iron and is heated. The cold roll revolves against the heated metal plate. This is the more economical and satisfactory ironing-machine, although its original cost is greater. The hot-roll machine may be heated by gas, or gasoline by a slight change involving a small expense. If power is available, the machine may be run by power. The use of one of these machines reduces greatly the time required to iron in the usual way. Garments with gathers and sleeves cannot be thus ironed to look perfectly smooth and well shaped, but all bed and table linen, towels, handkerchiefs, stockings, such underwear as may not require perfect smoothness, kitchen aprons and the like, may be done successfully and satisfactorily.
