It is a very convenient size for family use and has been in use now long enough to assure perfection of adaptability for the home. In case this all-electric machine has a blow out, and to protect the clothes from burning on the shoe there is simple provision to guard against this and all ills. The shoe by a button works back and forth if necessary, and taken altogether it is a beautiful mechanism. A few excellent machines, too, have the two rollers instead of one. This is supposed to hold material firmer and work more expeditiously. GOOD POINTS In some cases the gas burner and electric heater are divided in the center so that the burner can be used on warm work without scorching the unused part of the roll. The machines should be so made that they are comparatively easy to clean. Levers are not quite as good as the automatic, adjustable feed-board, which insures ease of control. It is worked by raising and lowering. This brings the roll in contact with the ironing surface, the same principle as a hand iron is brought to and from its rest. The action also stops and starts the rotation of the roller. In other words, it is automatic and there is no possibility of the operator becoming confused at a critical moment. There are no levers to pull or switches to turn; the control is instinctive and always under the hands of the operator for instant use. Moreover, you can lay your work over the roll while idle, insuring a straight edge and start the work again at your convenience. Ironing on these machines is done on the same principle as with a flat iron, only instead of passing the iron over the goods, the goods are moved against a stationary iron. POWER AND FUEL Gas, gasoline and electricity are the fuels used to heat the machines. Electricity and hand-power turn them. Motors come from ¹⁄₈ to ¹⁄₄ horse power depending on the size of the machine. When buying one, be sure to tell agent whether you have Alternating Current (A. C.) or Direct Current (D. C.) and what voltage you have. Motors are generally supplied 110, 220 volts D. C. and 60 Cycle 110, or 220 volts A. C. (We are not considering here the belt driven larger sizes.) About ⁷⁄₈ of a pint of gasoline is used on the smaller size machine. Sometimes the amount increases to 1¹⁄₂ pints; from about 17 to 33 cubic feet of gas. In the case of electricity as fuel for high heat, 2.5 to 6 kilowatts are used. For medium 1.7 to 4. For low .85 to 2. The current driving the machine is from 180 to 320 watts per hour. SIZE
