Be it known that We, ALEXANDER Diinand ICHAEL Fisor'rnn, citizens of the United States, residing at West Allis, county of Milwaukee, and tate of Wisconsin, have inably located in a suitable housing 42, and the I ,vented new and useful Improvements in 1, rod 36' extends downwardly through a'suit- \cetylen eGas Generators, of which the folable passage 44 which may form a part of lowing is a specification. housing.

sai Our invention relates to improvements in As the hell 1 descends, the weight 34 comes acetylene gas generators with special referin contact with a rest 46, wh ence to that class of generators in which the, conti ued descent of the bell, the wei ht is carbid holder is mounted upon a reciprocatlifted ing gas bell.

The object of our invention is to .providei a form of construction in which the carbi'd i willbe released when the bell has descended a predetermined distance, and in which the released carbid will be distributed into the water of the generating chamber.

In the following descri tion, reference is bad to the accompanying rawings in which, the figure is a vertical sectionalvview of a 32. The extent to which the valve 1s opened is regulated by the set screws 18, which bell, although in the ordinary operation of the machine, suflicient gas willbe liberated to raise the bell before the set screws 18 come into actual contact with the flan 'e 20.

be generated, the bell is permitted to rise until it strikes a lever 50 connected with a valve 52 in the escape -the pressure. The lever .50 is preferably provided with an, anti-frictio n roller 55. The service ipe 56 leads from apoint with in the bell a ove the water line, downwardly through the, bottom 8 of the generator and outwardly to a filter 58, the lower portion of which is filled with coke or charcoal covered by a body of cotton or other fibrous Ina-- terial main 64, this main-being provided with a valve 66. The service pipe 56 is also provided with a valve 68. Y

The carbid holder is filled throu h a suitable door 70 which is normally'he' d in po sition by a clamping member 72.

nected for use in conjunction with erator.

A reci rocating gas holding bell is; arranged with its lower end submerged in the water of an annular chamber 2, formed between the outer wall3 of the generating chamber 4, and a wall 6 concentric therewith, the bottom 8 of the chamber 4 being extended to the wall 6 and forming also a bot tom for the annular chamber 2. The bell is guided by supporting posts 10 which are engaged by sultable rol ers 12 supported from the bell by brackets 14. Brackets 16 connected with the bell are provided with set screws 18 which are adapted for contact with an angle iron arm 20 connected with the upper margin of the wall 6, thus limiting the descent of the bell.

A carbid holder 22 is mounted upon the bell and is provided with a tubular portion 24 which extends within the ell and carries a deflecting cone 26 which is adapted to spread material dropping through the tube 24, and deliver the same laterally. toward the outer Wall of the chamber 4. The lower end of the tube 24 is preferably bell-n'lounted to facilitate this lateral disthe gem It will be observed that the setscrews tribution of the carbid. are provided with depending cushion s rings The tube 24 is provided in its upper por- 19 which contact with the run 20 in}; Vance tion with a conically tapered inner wall 30, of the set screws.
