The "Debruyne" generator comprises an equalising bell gasholder A placed alongside a generating tank B containing water into which lump carbide is discharged as necessary from each in turn of a series of chambers mounted in a ring above the generating tank. The chambers are removable for refilling, and when charged are hermetically sealed until opened in turn above the shoot C, through which their contents are discharged into the generating tank. The carbide contained in each chamber yields sufficient gas nearly to fill the gasholder. The discharging mechanism is operated through an arm E attached to the bell G of the gasholder, which sets the mechanism in motion when the bell has fallen nearly to its lowest position. The lip L serves for renewing the water in the generator, and the gas evolved goes through the pipe K with tap F to the gasholder. There is an eccentric stirrer for the sludge and a large-bore cock for discharging it. The gas passes from the gasholder through the pipe J to the purifier H, charged with heratol, and thence to the service-pipe.

Type: (1) Automatic; carbide-to-water.
This generating apparatus comprises an equalising gasholder A placed alongside a generating tank B, above which is mounted on a rotating spindle a series of chambers C, arranged in a circle, which are filled with carbide. The generating tank is closed at the top, but on one side there is a shoot D through which the carbide is discharged from the chambers in turn into the water in the tank. The series of chambers are rotated by means of a cord passing round a pulley E and having a weight F at one end, and being attached to the bell of the gasholder at the other. When the bell falls, owing to the consumption of gas, to a certain low position, the carbide chamber, which has been brought by the rotation of the pulley over the shoot, is opened at the bottom by the automatic liberation of a catch, and its contents are discharged into the generating tank. The contents of one carbide chamber suffice to fill the gasholder to two-thirds of its total capacity. The carbide chambers after filling remain hermetically closed until the bottom is opened for the discharge of the carbide. There is a sludge-cock G at the bottom of the generating tank. The gas passes from the gasholder through a purifier H, which is ordinarily charged with puratylene.
(2) Non-automatic; carbide-to-water. This apparatus comprises a storage bell gasholder J placed alongside a generating tank in the top of which is a funnel E with a counter-weighted lever pivoted on the arm B. The base of the funnel is closed by a flap valve C hinged at D. When it is desired to generate gas the counter-weight A of the lever is raised and the valve at the bottom of the funnel is thereby opened. A charge of carbide is then tipped into the funnel and drops into the water in the generating tank. The valve is then closed and the gas evolved goes through the pipe G to the gasholder, whence it passes through a purifier to the service-pipe. There is a sludge-cock on the generating tank.
