thereof. It is well known that the generation
of acetylene by the mutual decomposition of
carbid and water is attended by considerable
heating of the parts of the generator; but the
5 construction of my generator for the recep-
tion of the cooling-bath makes provision for
the maintenance of the generator in a com-
paratively-cool condition. The generator is
arranged within the waste - receptacle in a
io manner to expose its open upper end through
the bell-head, so that ready access can be ob-
tained to the cooling-chamber 18 for replen-
ishing the cooling-bath therein without re-
moving the generator from the apparatus.
15 Although-I have shown and described the
generator as consisting of the connected con-
ical and cylindrical shells, I do not desire to
strictly confine myself to this specific con-
struction, because I am aware that the gen-
2o erator may consist of two cylindrical shells
arranged concentric with each other and
united together at their lower ends by any
approved means. The generator is provided
at its lower end with a transverse opening
25 20. Within the inner shell 16 of the genera-
tor is arranged a carbid vessel 21, which, as
shown by the drawings, is constructed of
sheet metal perforated throughout its area,
although any other foraminous material may
30 be employed. Said vessel is provided with a
stem 22, having an angular foot 23, the latter
adapted to fit in the opening 20 of the gener-
ator, so as to support the carbid vessel in an
elevated position and removably, within the
35 inner shell 16.
It is to be observed that the waste-recepta-
cle 14 is arranged removably within the float-
able bell"and that the generator is arranged
within this waste-receptacle. - The generator,
4o however, has no positive or direct connection
with the waste-receptacle; but, on the other
hand, I employ separable gas-pipe connec-
tions between the generator and the head of
the floatable bell, said connections being con-
45 structed to suspend the generator within the
waste-receptacle and to permit the expedi-
tious removal of said generator from the bell.
24 25 designate short lengths of gas-pipe.
which are fastened to the bell-head, on oppo-
5o site sides of the opening 13 therein, each pipe
having a stop-cock 26. A cross-pipe 27 has
depending branches which are united separa-
bly by the couplings 28 to the short lengths
of gas-pipe 24 25. A sectional connecting-,
55 pipe 29 30 is between the cross-pipe and the
head 19 of the inner shell of the generator,:
one section of the pipe being made fast with
the generator-head and the other pipe-section
being united to the cross-pipe 27 by the T
6o connection 31. A coupling 32 unites the two
members of the pipes separably together, said
couplings 28 and 30 being of any construction
suitable for the purpose. The generator is
made fast with the lower section of the sepa-
65 rable pipe, and this pipe is supported by the
cross-pipe, which in turn is attached to the
short lengths of the pipe fastened to the bell-head. The described construction provides
means for suspending the generator within
the waste-receptacle and also establishes the 70
gas-outlet from the generator to the chamber
of the floatable bell. It is evident that the
couplings 28 may be manipulated to release
the cross-pipe 27 from the short lengths of
pipe 24 25, and this cross-pipe, together with 75
the sectional pipe and the generator, may be
removed for the purpose of enabling an at-
tendant to reach the stem 22, whereby the
carbid-receptacle may be withdrawn for ready
access thereto in cleaning and recharging the 8o
same.
The bell is guided in its vertical travel by
the vertical rods 33 and the keepers 34. The
rods are fastened-at their upper ends to the
lengths of pipe 24 25 and the keepers are at- 85
tached to opposite sides of the tank 10. The
rods are adapted to travel with the bell and
are fitted in the keepers to slide therein in
order to direct the bell in its traveling play
within the tank under variation in the vol- 90
ume and pressure of the gas. Stops 35, fas-
tened to the lower ends of the rods, limit the
upward movement of the bell by impinging
the keepers. The gas is carried from the ex-
pansible tank by a pipe 36, having a branch 95
37, indicated by dotted lines in Fig. 2, dis-
posed within - the tank and extending up-
wardly from the bottom thereof to a 'point
above the water-line. A relief-trap 38 is
coupled to the lower end of the gas-pipe, said 100
trap adapted to receive a quantity of water,
which forms a seal therein to prevent, nor-
mally, the escape of gas through the trap.
When the gas attains a pressure sufficient to
overcome the head of the -water seal in the 105
trap-as, for instance, a pressure exceeding
four ounces to the square inch-the water
seal is displaced from the trap automatically
and the gas finds a vent through said trap,
thus making provision for automatically vent- r11o
ing the apparatus and minimizing the liability
of explosion.
The operation is as follows: The vessel 21
having been charged with carbid, it is slipped
into the generator to assume a position for 115
its foot to enter the opening 20, and the gen-
erator is now arranged in the waste-recep-
tacle,. which is arranged in the open-ended
cylinder of the bell. The couplings 28 are
manipulated to make the cross-pipe fast with 120
the short lengths of pipe 24 25, thus suspend-
ing the generator within the waste-receptacle.
The bell settles in the tank, while the water
flows into the openings 15 of 'the receptacle
and fills the latter to a point sufficient to 125
reach the carbid in the vessel .21, the water
having free access to the -carbid through the
open lower end of the generator. The water
attacks the carbid for the instantaneous gen-
eration of gas, which flows through the pipe 130
29 30, the cross-pipe, and the short lengths
of pipe 24 25 into the floatable bell, the:stop-
cocks 26 being. opened. The accumulation
of gas lifts the bell and the parts attached2
