The pressure of the gas is
varied as desired by altering the height of water in the tank _A_.
When cleaning the machine, the water must never be run below the top of
the generating chamber.
[Illustration: FIG. 24.--"SICHE" GENERATOR.]
AMERICA--UNITED STATES.
_Maker:_ J. B. COLT CO., 21 BARCLAY STREET, NEW YORK.
_Type:_ Automatic; carbide-to-water.
The "Colt" generator made by this firm comprises a carbide hopper mounted
above a generating tank containing water, and an equalising bell
gasholder mounted above a seal-pot having a vent-pipe _C_
communicating with the outer air. The carbide hopper is charged with 1/4
x 1/12 inch carbide, which is delivered from it into the water in the
generating tank in small portions at a time through a double valve, which
is actuated through levers connected to the crown of the equalising
gasholder. As the bell of the gasholder falls the lever rotates a rock
shaft, which enters the carbide hopper, and through a rigidly attached
lever raises the inner plunger of the feed-valve. The inner plunger in
turn raises the concentric outer stopper, thereby leaving an annular
space at the base of the carbide hopper, through which a small delivery
of carbide to the water in the generating tank then ensues.
