COMPLETE SPECIFICATION.
Improved Apparatus for Generating Acetylene Gas.
We, JOHANNES MÜCKE and JOSEPH MÜCKE of 14 Holzmarktstrasse, Berlin,
Germany, Manufacturers, do hereby declare the nature of our invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
The present invention relates to acetylene-gas-generators and consists of the
details of construction herein after particularly pointed out.
And in order to render the present specification more easily intelligible reference
is had to the accompanying drawing, in which similar letters of reference denote
similar parts throughout the several views:-
Fig. 1 is a diagramatical view of the apparatus.
Fig. 2 a detail of a condenser or water trap.
Fig. 3 a modified form of condenser or water trap.
The apparatus consists of the water tank a of the generator, in which is arranged
the bell b, having dome c for the gas outlet pipe. Underneath the bell are arranged
the calcium carbide receptacles e having each a cover f, advantageously formed
with turned down edges at 9 and resting on the said receptacle, with the edges
extending beyond the walls of the same. The receptacles are arranged at different
heights so that the water entering the generator tank, cannot reach all the receptacles
at once, but fills them successively. The calcium carbide within the receptacles,
is covered by a bell i having a small upper outlet k through which the gas escapes.
The object of this bell is to force the gas generated to pass through the milk of
lime formed by the generation. The bell will cause the generation of the acetylene
gas to commence at the top of the bell close to the water inlet, consequently the milk
of lime formed will remain here instead of being able to dissolve. The opening k
only allows a part of the gas developed to escape, whilst the rest will have to pass
through the milk of lime formed underneath the bell.
The gas supply pipe d, is provided with suitable condensers or water traps x at
suitable points of its length as at z, said water traps serving to take the water out
of the pipe system, which is deposited by the gas. These condensers or traps,
may either consist of a receiver a¹, into which a dip pipe from the main extends as
at Figure 2 or they may consist of a bend s s¹ formed in a branch pipe which com-
municates with the main in the manner shown at Figure 3.
The water supply comes from the tank 7, having a cock or plug n in its bottom,
communicating by means of a cord or chain with a lever arm m, which may be in
connection with and operated by the rising and falling of the gasometer bell.
From 1 the water passes to a cistern o, from which it is carried off by means of a
syphon p, the longer arm of which extends into the water supply pipe g leading
to the generator. The syphon p may be adjustable in height in order to regulate
the water supply to the generator.
The operation of the device will be clear from the foregoing description:-The
water entering the generator, rises gradually therein, filling the calcium carbide
receptacles successively and generating the acetylene gas. The water will flow into
the receptacles e underneath the lids of the same without displacing them. The

page_text: downwardly bent edges of the covers, which should extend below the water level
outside the receptacle, will force the gas generated to pass through the water
outside the receptacle-and thus purify the same.

1
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
-
1-Acetylene gas generator, having closed calcium carbide receptacles, a water
regulating cistern o and condenser or water trap & or a¹ the parts being so arranged
that the gas generated will be forced through the milk of lime formed in the gene-
ration, and then through the water outside the receptacle, the syphon p serving to
allow water to flow to the generator after the main supply of water has been cut
off substantially as described.
2: In the device covered by claim 1, the arrangement of a bell within the
calcium carbide receptacles, said bell having upper opening, in order to force
the gas through the lime milk formed and thus to keep back the phosphoretted
hydrogen contained in the calcium carbide.
2 The arrangement of a cover to protect the calcium carbide in the receptacles.
2b: The arrangement of a downwardly turned edge to the cover for the purpose
specified.
3: In a device covered by claims 1 to 2b, the arrangement of the syphon in the
cistern o, to enable the water to pass on to the receptacle in action, after the main
supply has been cut off, as described.

4: In an acetylene gas generator, the arrangement of an automatically operat
ing condenser or trap, by means of which, either by a bend or by a tank (Figs. 2
and 3) the water taken into the system by the gas may be withdrawn from the
same substantially as described.
