The common gas jet is illus-trated in Fig. 193. The figure shows a bracket fixture whichis generally fastened to a pipe in the wall. A swing-joint at Apermits the flame F to be moved into different positions. Theannular opening A permits the gas to pass to the jet in anyposition to which the light is moved. The gas-cock C is a cone-shaped plug, which has been ground to perfectly fit its should move with perfect freedom, and yet prevent the es-cape of the gas. A slotted screw N permits the joint to be re-adjusted, should the plug become loose in the socket. The gas-tips T are made of a number of different kinds of.

The bottom of thetip is cone-shaped, which permits it to be forced into place in theend of the tube with a pair of pliers. 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
