In size the tips are gradedby the amount of gas which they will allow to escape in cubicfeet per hour. For example—a 4-foot tip will use approximately4 cubic feet of gas per hour. They are made in a number of sizesto suit the varying requirements. The Inverted-mantel Gasoline Lamp.—The inverted-mantlegasoline-gas lamp shown in Fig. 194, furnishes a good example ofmechanism and principle of operation, when used with the hollow-wire system. This is the bracket style of lamp but the samemechanism is used in other forms of fixtures. Lamps of similar.

In Fig. 194 the lamp consists of a bracket //, which is securedto the wall and through the stem of which the gasoline is con-ducted to the generator by the pipe W, The arrows show thecourse of the gasoline and its vapor as it passes through the entering the generator the gasoline first passes, the percola-tion, through an asbestos wick B, the object of which is to pre-vent the vapor pressure from acting dii-ectly on the gasoline inthe supply tube. The gasoline passes through the wick B,largely by capillary action, as it must enter the generator againsta pressure greater than that afforded by the pressure tank. The 280 MECHANICS OF THE HOUSEHOLD vaporization of the gasoline takes place in the tube above themantle T, from the flame of which it receives the necessary heat. In lighting the lamp an asbestos tor
