_Type_: Automatic; carbide-to-water.
The "Javal" generating plant made by this firm consists of an equalising
bell gasholder _A_ in the tank _B_ with a series of buckets
_D_, with removable bottoms _h_, mounted on a frame _F_
round the guide framing of the holder. Alongside the gasholder stands the
generating tank _H_ with shoot _K_, into which the carbide
discharged from the buckets falls. On top of the generator is a tipping
water-bucket _I_ supplied with water through a ball cock. The bell
of the gasholder is connected by chains _a_ and _c_, and levers
_b_ and _d_ with an arm which, when the bell descends to a
certain point, comes in contact with the catch by which the bottom of the
carbide bucket is held in place, and, liberating the same, allows the
carbide to fall into the shoot. When the bell rises, in consequence of
the evolved gas, the ring of carbide buckets is rotated sufficiently to
bring the next bucket over the shoot. Thus the buckets are discharged in
turn as required through the rise and fall of the gasholder bell.
[Illustration: FIG. 35.--"JAVAL" GENERATOR.]
The carbide falling from the opened bucket strikes the end _i_ of
the lever _k_, and thereby tips the water-bucket _I_ and
discharges its contents into the shoot of the generator.
