Alcohol is used forgenerating the vapor supply, because the flame does not blackthe iron and fill the room with smoke as in the case when gasolineis used for the purpose. When the alcohol is ignited, the coveris placed in position as shown in Fig. 204, so that the flame mayheat not only the generator but also the tank. The object ofheating the tank is that the heated gasoline may furnish pressurewith which to force the gasoline into the generator. When thealcohol used for generating is almost burned out, the valve F isslightly opened and the burner lighted. As shown in Fig. 205, the generator G is a brass tube, inclosingthe valve-stem G, which terminates in the needle-valve F. This.

When the gasoline in the tankhas been heated the necessary amount, the vapor in G is allowedto escape through the valve V. The vapor is discharged intothe Bunsen tube, and with it the air is carried in through theopenings E, from both sides of the iron. The burner is a brasstube, slotted as shown at H, through which the gas escapes,forming a short flame of large area close to the part of the ironto be heated. The size of the flame is regulated by the hand-wheel F. The tank is entirely closed, the plug P being provided with alead washer to insure a tight joint. The plug is further providedwith a soft metal center which acts as a safety-plug in case of 292 MECHANICS OF THE HOUSEHOLD overhea
