Abstract: 20,582. Chubb, H. R. Sept. 20. Acetylene.-Relates to apparatus for the generation and storage of acetylene and other gases, in which the carbide &c. holders are not rigidly connected to the gas holder or bell, but are connected in such a manner that the vertical movements of the holders and bell are not always equal. The bell a, Figs. 1 and 2, and the carbide &c. holders c are independently arranged in a water tank b, and are connected by wire cords &c. c<1>, e<3> and a system of pulleys &c. on a framing b<1> above the tank. The cord e<3> pass over pulleys to a double pulley e<2> on a spindle e<1> carrying a cam or involute disc or lever e, to which a cord d' passing round a pulley d on a shaft c<3> is attached. The holders c are separately connected by cords c<1> to pulleys c' on this shaft. The bell a is counterbalanced in all positions by a weight f connected by a cord f<1> to an involute disc or pulley g on the spindle e'. These arrangements provide for the described relative motions of the bell and holders. Each holder consists of an outer open-bottomed casing, within which is secured by bayonet joints &c. l<2> a second casing or holder j containing a tier of shallow holders k which fit together. The casing j and the holders k are provided with holes near the top for the entry of water from the tank b, the car. bide in the lower parts being first acted upon. A perforated cover supporting a filtering-layer l<1> may be fitted on the top of the casing j, to filter the gas which passes to the outlet pipe h<1>. The pipes h<1> are bent down against the exterior of the holders c and work over stand-pipes h in connection with a common pipe h<5>. A passage c<4> is provided in the walls of each holder c and its pipe h' under the normal water level to allow gas generated after the cocks h<2> are closed to escape, if under sufficient pressure, into the pipes h. Shut-off and drainage cocks h<4>, h<6> are also provided. The common pipe h<5> is connected by an external pipe to a condenser i, which may be within or without the bell a. In the case shown in Fig. 1, the condenser is within the bell and consists of two concentric pipes between which the gas flows upwards to the outlet notches n<2> under the condenser cover. If the condenser is outside of the bell, the gas passes down between the tubes, and then rises within the inner tube to the upper end of a stand-pipe, which leads it to a second stand-pipe within the bell but outside of the condenser. A series of radial and concentric divisions of sheet metal may be attached to the bottom of the tank b within the bell, to prevent excessive motion of the water when the apparatus is used upon a vehicle or ship. A suitable safety-valve consists of a stand-pipe q standing above the water level in the tank b and connected to the gas inlet to the condenser ; communication between the pipe q and a second standpipe r, in connection with the open air or fitted with a burner, is normally cut off by a partition q<2> within a pipe or cap q<1>, which covers the upper ends of the two stand-pipes. The gas bell, the balance weight f, or any of the moving parts are arranged to lift the cap q<1> when the bell reaches its upper limit of movement. The partition in the cap may consist of an inner tube, or may be dispensed with if the safety-valve is placed within the bell. In small generators, the carbide &c. holders are placed in a well formed in the centre of the gas bell, and are supported by horizontal rods resting on the top of the bell and passing through lugs on the outlet pipes h<1> of the holders. The variation in the position of the holders, which is, in the generator shown in Figs. 1 and 2, obtained by the use of hooks m and several links m<1>, is, in the case of small generators, obtained by fitting the lugs with several holes for the reception of the supporting-rods.
