The flow of water to the generator is visible.
_Maker_: THE ACETYLENE GAS AND CARBIDE OF CALCIUM CO., PONTARDAWE,
R.S.O., GLAM.
_Type_: Automatic; water-to-carbide; flooded compartment.
The "Owens" generator made by this firm comprises an equalising bell
gasholder alongside which are placed two or more inclined generating
cylinders. The front lower end of each cylinder is fitted with a lid
which is closed by a screw clamp. There is inserted in each cylinder a
cylindrical trough, divided into ten compartments, each of which contains
carbide. Water is supplied to the upper ends of the cylinders from a
high-level tank placed at the back of the gasholder. In the larger sizes
the tank is automatically refilled from a water service through a
ball-cock. The outlet-valve of this tank is operated through a counter-
weighted lever, the unweighted end of which is depressed by a loop,
attached to the crown of the gasholder bell, when the bell has nearly
reached its lowest position. This action of the bell on the lever opens
the outlet-valve of the tank and allows water to flow thence into one of
the generating cylinders. It is discharged into the uppermost of the
compartments of the carbide trough, and when the carbide in that
compartment is exhausted it flows over the partition into the next
compartment, and so on until the whole trough is flooded.
