- FIG. II Said bottom plate is represented by Fig. II, in the drawings.
- the top part of the air chest ismade in the same form as the bottom, with two tubes (see Figs. III, and V, letter g, in the drawings) ⁇ or orifices, raised about two inches, near the sides of the air chest, directly opposite, each to the other, and pointing, each toward the other,
- the first mentioned tube is to be made stationary in the back of the forge, and the air chest is made to vrevolve horizontally around the small end of the stationary pipe, thereby enabling anyone totake a long or short welding hea-t at pleasure, that is by turning the air chest so that the air pipes point, one to, and the other from the back of the forge, a short ⁇ heat is obtainedyand by turning the air chest so that the air pipes point crosswise of the forge, a long heat is obtained; and the air being received in the center, a much more unbroken current of air is obtained than with the twyers now in use, and there is a great saving in coal, by using this twyer.
