Abstract: 24,360. McGinn, J. St. L. Dec. 7. Acetylene. - Relates to generating- apparatus in which measured quantities of water are automatically delivered bv the fall of the bell of the gas holder. The generator consists of a circular casing 5, cut up by radial partitions into four compartments 34, 35, 36, 37. In each compartment there is a pair of semicircular cup-supporting standards 46, each having a row of central slots 49, and a number of edge slots 50 into which pins 60 of the cups or special carbide receptacles are placed. These receptacles are held by staples 61 thereon engaging with levers 51. When the levers are operated, the receptacles are released and fall into the water. The casing 5 is provided with a water pocket 9, into which the depending flange 10 of the lid 12 dips. The lid has also an upper flange 13, one portion 14 of which is higher than the rest, and, with parallel side walls 25 and a tube 20, forms a small sealing- chamber 26. Fixed upon the lid are two tubes 15, 16, each provided with a cover 17, one of which is weighted, while the other is surrounded by a tube 18 having a water pocket 20 on its outer side forming a seal for the lower end of a tube 21 which is carried by the gas delivery pipe 22. The gas holder is formed of an inner closed drum 72, connected to an outer casing formed of two parts 70, 170. The annular space between the drum and casing forms a liquid seal for the bell 71. Through the drum 72 pass gas delivery and exit pipes 22, 180 and a large central tube 74, communicating by a radial tube 75 with the outer annular water space. The bell 71 has a central tube 76 to which a rod 101 carrying an indicator 100 is attached. As the bell falls, the lower end of the tube 76 operates a lever 198, a connecting- rod 197, levers 97, 99, and a bell-crank lever 95, whereby a valve 85 in the water-measuring chamber 82 is operated and the water is discharged down a tube 104 to a shoot 105, which is likewise tilted by the action of the bell-crank lever to deliver the water to a chamber 108. This chamber contains a hand-operated device for directing the water to the outlet 109 as shown, or to an outlet 110 for another generator. The water flows down a tube 23 on the outside of the tube 21, fills the water seal 19, and overflows through an opening 29 to the chamber 26, from which it partly passes through the opening 27 to the interior of the tube 18, and partly overflows through an opening 28 to the water pocket 9. From the latter it overflows through an opening 41 to the compartment 34. As it rises in this compartment, it causes a triangular float 62 to rise within guides, and this float releases in turn each carbide receptacle. When all the receptacles in that compartment have been precipitated into the water, the water rises to the top, and overflows through an opening 38 to the compartment 35, and so on by openings 39 and 40 to the compartments 36 and 37. The liberated gas raises the cap 17, and escapes to the bell 71. The outer shell 70 is open to the atmosphere through the tube 181. To clean out and recharge the generator, the cap 17 is removed, the lid is raised, and the generator drawn away, and then cleaned out, recharged, and replaced.
