Improvements in Acetylene Generators.
I, ANTOINE COMBIER, of Pierre Bénite, Dep. Rhone, in the Republic of France,
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
This invention relates to improvements in acetylene generators.
In the annexed drawings:-Fig. 1 is a central vertical section of the generator,"
Fig. 2 a cross section on line 2-2 of Fig. 1, and Fig. 3 a vertical section on
line 3-3 of Fig. 2.
A is the generator forming a double reservoir with a single bottom, the interior
reservoir receives the water which is intended to react on the carbide of calcium
to produce the gas, the exterior reservoir receives the gas bell C which ascends
and descends therein. This outer reservoir is filled with water or non fugitive oil
or glycerine to avoid freezing.
In the middle of the upper part of the bell C is an automatic feed hopper for the
carbide its entrance being closed by a screw cap C¹. This hopper tapers downwardly
and has at its lower end an opening. A rod passes through this opening and
carries two valves S1 S preferably in the form of spheres, one S above the opening,
the other S below the opening. The valves S S are spaced for a distance apart
equivalent to the amount of a charge of carbide. The rod S is continued below,
the valve S and has guiding in a tube T rising from the base of the reservoir A,
and the upper end of the tube T' serves as a seat for supporting the valve S. Below
the valve S is a tube S3 serving as a shield to prevent carbide possibly falling
into the tube T. To relieve the valve S₁ from the superincumbent weight of the
carbide in the hopper R a roof like shelter P is made and suspended on rods Pi
from a ring 12 near the mouth of the hopper so that said shelter lies over the
valve S, a sufficient space being left around the edge of the shelter within the
hopper to permit carbide to leave the hopper. A gas tube Frises within the bell
where its inner end has a hood F¹ to prevent splashes of water entering the tube.
Funnels EE are provided for purposes of filling the two compartments of the
double reservoir. V is a cock for emptying the reservoir, F a removable catch
bulb for condensed moisture in pipe F. The bell Chas three rods C2 by which it
is guided in tubes I on the outside of the reservoir A. On the bell C are also
pins H and on the reservoir A are hinged plates J having in each a series of
perforations to engage the pins H and hold the bell C.
The operation of the generator is as follows:
The parts being in the position shown in Fig. 1 the reservoir compartments
being charged and the hopper R also, and the latter closed while the bell is held by
the pins H and plates J in such a position that the valve S closes the hopper
below, the plates J are now folded down and the pins H released. The bell will
then fall and carbide will pass under the valve S which cannot fall further owing
to the-valve S resting on the end of pipe T. Carbide thus falls into the water
and gas is developed which raises the bell allowing the valve Sto again fall on
its seat so that the supply of carbide is stopped. That which has fallen being not
yet exhausted is presumed to be sufficient to provide a full charge of gas, and when

page_text: the latter has been used the bell in falling will eventually pass again below the
position illustrated in Fig. 1 another charge of carbide will fall and the process
will be repeated unless the fall of the bell is limited by the engagement of the
plates J and pins H.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
-
1. In an acetylene gas generator the combination of a generator body comprising
an annular compartment and a central compartment of a bell dipping in said
annular compartment and means for supplying carbide to said central compartment.
2. In an acetylene gas generator. the combination of a generator body adapted
to contain water a bell having its edges sealed and adapted to rise and fall over
said generator body, a hopper in the said bell. having an opening into the interior
thereof, a rod, two valves on said rod spread from one another, one above and
one below said hopper opening, a support for the lower. valve in said generator
body a shielding roof in said hopper for the upper valve.and an outlet pipe from
said bell for the purpose set forth.
3. In an acetylene gas generator the combination of a generator body, a bell
thereover having its edges sealed and adapted to rise and fall under the pressure
of the gas therein, a féed hopper in the said bell and having an outlet, into the
bell a valve for automatically closing said outlet while the bell is above a pre-
determined minimum distance above its lowest position and a detachable locking
device for retaining the bell at or above: said distance.
