9743. Deike, A. H., Alexander, A. W., and Mitchell, J. May 9. Acetylene.-Relates to apparatus for generating acetylene by automatically supplying carbide to water. The generator 1 is provided with two or more carbide holders 6, which are inserted through openings 12 which can be closed airtight. Each holder rests upon two rods 11, and is formed with a bottom composed of a number of independent hinged sections 9. At first these sections are held in the closed position by supports 16 pivoted on rods 15, 15<a>, there being one support for each section. The supports are thrown one at a time on one side, so as to let a section fall each time the bell of the holder sinks. The bell in descending engages with the hooked end of a rod 28 connected to a bellcrank lever 26, 27, the other end of which is connected by a link 25 to a second bell-crank lever 23, 24, from which motion is imparted by a link 22 to a lever 21 having a dog 21<a> which engages the teeth of a ratchet-wheel 20, and thereby causes the latter to rotate slightly each time the bell descends. The ratchet-wheel 20 is mounted upon a shaft 17<a>, upon which are spirally arranged a series of projecting pins. which successively operate the supports 16 of the carbide sections. Pinions 19, 19<a>, rigidly mounted on the shafts 17, 17<a> and gearing together, cause the sections of each holder to be released simultaneously. The gas passes to the holder by the pipe 31.
