_Type:_ Automatic; carbide-to-water.
The "Davis" generator made by this firm comprises an equalising bell
gasholder with double walls, the inner wall surrounding a central tube
rising from the top of the generating chamber, in which is placed a
water-sealed carbide chamber with a rotatory feeding mechanism which is
driven by a weight motor. The carbide falls from the chamber on to a wide
disc from which it is pushed off a lump at a time by a swinging
displacer, so arranged that it will yield in every direction and prevent
clogging of the feeding mechanism. Carbide falls from the disk into the
water of the generating chamber, and the evolved gas raises the bell and
so allows a weighted lever to interrupt the action of the clockwork,
until the bell again descends. The gas passes through a washer in the
gasholder tank, and then through an outside scrubber to the service-pipe.
There is an outside chamber connected by a pipe with the generating
chamber, which automatically prevents over-filling with water, and also
acts as a drainage chamber for the service- and blow-off-pipes. There is
an agitator for the residuum and a sludge-cock through which to remove
same.
