Abstract: 8989. Kerr, J. G., and Fry, C. April 8. Acetylene. - The generator A consists of a chamber E standing in a water seal D, formed in the base-plate, and containing a rotatable table G which is mounted upon a rod F by means of a tube H continuous with a sleeve G<1> provided with a handle F<1>. Upon the table G are four receptacles M for carbide containers K' which can be successively brought beneath a cylinder 0 in the cover by rotating the table. The boss a on the bottom of the table and one on the base-plate are formed with notches and projections to ensure exactness of position. The carbide containers K<1> can be removed and recharged during the working of the apparatus as follows :-The table is raised by turning the pinion H<1> which gears with circular teeth on the sleeve G', and the receptacle K<1> is then brought up into the cylinder 0 which passes into a water seal N. The gas in the cylinder escapes by a cock and pipe U, T back into the generator, and the residue is brought off by lighting the burner S. The cover Q is then lifted out of the water seal P, and the receptacle K' is removed and recharged. Water is supplied to the carbide receptacles K<1> from a tank V<1> by a siphon A<11> which discharges by a pipe C', B', A' into a water seal E' about the rod D' of an agitator, whence the water overflows into the receptacle K<1>. The gas produced passes into a holder M<1> by a pipe N' and leaves it by a pipe O<1>. The vertical movement of the bell upon the rod R", rising from the bottom of the tank L', controls the supply of water to the carbide by raising or lowering the siphon A<11>. This is suspended by a cord B" which passes over pulleys h, j, k, m to the bell and is provided with a weight i and knots n and o. When the bell is in its lowest position the knot n is jammed in the lower pulley as shown, and as the weight i is thus carried by the bell, the siphon A<11> is free to descend to its lowest position. Water then runs over from the tank V<1> to the carbide receptacle. When the bell rises, the cord runs off and the weight i raises the siphon until the point of connection between the legs e and f, Fig. 3, which is open to the air, is above the level of the water in the tank V<1>, and the supply is thereby cut off. Upward movement of the siphon is limited by the knot o jamming in the pulley h. The legs f and g hold sufficient water to set the siphon at work again when it is again lowered by the descent of the bell. Attention is called to the generator, when one of the carbide receptacles is exhausted, by an electric bell. This is put into action by a nut D<11>, upon a rod C<11> carried by the holder, bearing upon a spring p carried by an insulated binding-post E<11> when the bell descends to a low position. The spring p is thus brought into contact with the frame s' and completes the electric bell circuit through the uninsulated post F<11>. If more gas should be produced than the holder will contain, the excess escapes under the pipe Q<1> and is conducted thence by a pipe P<1> to the open air.
