The feeding mechanism permits the discharge of lump carbide, and
the weight motor affords independent power for feeding the carbide, at
the same time indicating the amount of unconsumed carbide and securing
uniform gas pressure.
[Illustration: FIG. 26.--"DAVIS" GENERATOR.]
_Maker:_ SUNLIGHT GAS MACHINE CO., 49 WARREN STREET, NEW YORK.
_Type:_ Automatic; carbide-to-water.
The "Omega" apparatus made by this firm consists of a generating tank
containing water, and surmounted by a hopper which is filled with carbide
of 1/4-inch size. The carbide is fed from the hopper into the generating
tank through a mechanism consisting of a double oscillating cup so
weighted that normally the feed is closed. The fall of the bell of the
equalising gasholder, into which the gas evolved passes, operates a lever
_B_, which rotates the weighted cup in the neck of the hopper and so
causes a portion of carbide to fall into the water in the generating
tank. The feed-cup consists of an upper cup into which the carbide is
first delivered. It is then tipped from the upper cup into the lower cup
while, at the same time, further delivery from the hopper is prevented.
Thus only the portion of carbide which has been delivered into the lower
cup is emptied at one discharge into the generator.
