We now proceed to describe the part of the apparatus with which the workman operates. In fig. 2, the flexible tube, m, is attached to one arm of the forked tube, o; the other arm of o is attached to a pipe, q, proceeding from a bellows, or other means for supplying air. The solderer may work a bellows with his foot to supply his apparatus with air, or the men in a whole factory may be supplied from a blowing apparatus. A cock, n, regulates the supply of gas; p is a cock for regulating the supply of air; r is the pipe or tube in which the gas and air are mixed; s, the beak or tool, from which issues the jet of flame, t, with which the workman operates.
The forked tube, o, is attached to the girdle of the workman, and the regulating cocks, n and p, are so placed, that by using one hand, the man can allow the exact proportions of air and gas to issue. By stopping both cocks, the flame is of course extinguished.
The beak, s, may be exchanged for others of every variety of form, so as to produce jets of flame adapted to any kind of work. Fig. 3 is a tool formed like the rosette of a watering-pot, capable of producing a most intense flame of jets.
