Abstract: 7801. Chubb, H. R. April 3. Acetylene. - The gas bell d, Fig. 1, and generating-chambers e of an acetylene generator are mounted together on a lever frame a which turns on trunnions b on the inner sides of the water tank c, the bell being thereby relieved of part of the weight of the chambers e and the carbide holders g, h, Figs. 1 and 2, contained in them. The bell d in the generator, shown in Figs. 1 and 2, is rigidly connected to the frame a, which is arranged to receive two chambers e placed side by side in front of the bell d. Each chamber e is fitted with eccentrically-pivoted pieces e', which may rest with any of their edges on the upper edges of the frame a, to allow the chambers to be set at different levels. The chambers e are all open at the bottom, and each supports by a cross-rod j &c. a deep holder g carrying a tier of shallow holders h ; the bottoms g<2>, h<2> being coned &c. so that water entering through the holes g<1>, h<4> attacks the lowest layers of carbide first. The gas generated passes through purifying material i<1> on the perforated covers of the outer holders g, and escapes through pipes p to flat tubes f<1> placed over the stand-pipes f, which communicate with the ascension pipe f <9> in the bell d and also with the service main f <7> &c. Gas generated after the cocks f are closed escapes into the tubes/ through openings f<3> in the tubes f<1> and chambers e under the normal water level. The frame a may be counterbalanced, or the bell d shaped as shown in Fig. 1, to compensate for its variable effective weight when at different heights, and so to maintain a uniform pressure. The ascension pipe f <9> extends up into a suitable extension d' of the bell within a hollow chamber d<1> which prevents the bell from being covered by the water. Excess gas escapes from the bell through a pipe k and a flexible pipe k<2> to a burner situated close to a flame. Fig. 4 shows a modification suitable for larger apparatus, and provided with three chambers e and a gas bell d all slung from the frame a. In this case, a condenser, consisting of inner and outer tubes o', o, is provided in the tank c between the stand-pipes f and the bell d. The condenser may be within the bell, in which case the gas passes upwards between the tubes o, o<1> and out through the perforated upper end, or it may be outside the bell ; in the latter case, the gas enters at the upper end, passes down between the tubes, and escapes to the bell through a stand-pipe within the tube o'. When the bell reaches its upper limit of motion, an arm n carried by it strikes and rises a divided hood l<1> placed over and separating a stand-pipe l and an escape pipe m in the pipe c, so that excess gas then escapes ; the hood l<1> and the pipe m may be within the bell, the pipe l being then unnecessary. The water space within the bell may be divided off into compartments by radial ribs and concentric rings on the bottom of the tank, to prevent excessive motion of the water when the generator is employed on a vehicle or ship. The frame a may carry only the generating-chambers, and be actuated by a bell separately mounted in the same or in another tank.
