Abstract: 897. Rosenbluth, E. M. Jan. 14, 1905, [date applied for under Patents Act, 1901]. Acetylene.- Relates to acetylene apparatus in which gas is generated by bringing the carbide into contact with the moist residue by inverting the generator, and is described in combination with a lamp for use in surgical and other operations. In the arrangement shown in Fig. I, a generator 8 is supported by trunnions in a yoke 3 forming part of a tripod stand 1. A telescopic standard 11 above the yoke supports an horizontal tubular rod 18 which carries at its end a rotary coupling 21 to which is pivoted a lamp casing 27 turnable in any direction by means of a handle 30. Gas is conducted from the hollow trunnion 7 to the rod 18, and thence to the burner by means of flexible tubes 53, 48. The generator 8, shown in Fig. III, comprises a rectangular outer casing secured to the outlet trunnion 7 by a flange 65 and containing a casing 66 within which the carbide chamber is enclosed. Removable caps 76, 77 are secured upon the ends of the generator casing, and the chambers so formed communicate with the interior of the casing by apertures 81 in the wall 80 of the generator. The space within the cap 76 communicates with the interior of the carbide chamber through a bush 84 in which works a plunger 87. Water, passing through the bush 84 from the chamber 67 when the generator is inverted, is distributed over the moist carbide residue 88 by means of a cone 96, porous pad 99, and channelled plate 98. Particles of dry residue pass into a chamber 94 through a perforated diaphragm 93, when the generator is in its inoperative position. A vacuum valve 100, Fig. II, is provided and is opened to allow the water to rise into the carbide chamber. The evolved gas passes through openings 69 to the trunnion 7, where it is filtered by absorbent cotton 62 and ashes 61 on its way to the outlet 55. The generator may be inverted by handles 101, and is stopped in the required position by a pin 112 engaging lugs 103, 105. A spring bolt 108, adapted to engage recesses 110, 111, is provided to prevent accidental displacement. A generator &c. such as described may also be supported from a vertical wall. In the arrangement shown in Fig. VII, a modified 'form of generator is adapted to be supported in a frame 115 to be secured to a wall carrying lower and upper sectional bearings for the trunnions of a generator, the upper sections 120, 121 being pivoted to the frame 115 by bolts 123, 124 and carrying by means of lugs 134, 135 swing bolts 129, 130 provided with wing nuts by which they can be engaged with the lower bearing so as to clamp the trunnions. The generator is secured to flanges of the trunnions by means of bolts 146, 147 and comprises a rectangular water reservoir and cylindrical carbide chamber arranged in a similar manner to that described. The caps are secured upon the ends of the carbide chamber by means of bifurcated lugs 157 and swing bolts 158 provided with wing nuts. The water chamber is provided with a false bottom, which supports the carbide chamber and is cut away at the corners to allow water to pass beneath it and have access to the inlet to the carbide. The interior of the carbide chamber is provided with a flange to keep the moist residue in position. This form of generator may also be employed in conjunction with a vertical standard.
