Improvements in Apparatus for Manufacturing Acetylene Gas.
I, JOHN HENRY EXLEY, of Byram Street, Huddersfield, in the County of York,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in apparatus for manufacturing acetylene
gas and particularly to that class of apparatus in which the surplus gas over
and above what is immediately being consumed passes into the holder.
In the accompanying sheet of drawings forming a part of this specification
Figure 1, represents an elevation partly in section of an acetylene apparatus fitted
with my improvements.
Figure 2, is a plan of the same.
The generators A, A³ are fitted on each side of the holder B and the water
passages C and C² connect them to the holder. The gas passages D and D³ are con-
nected to the two cooling coils D³ and 1 located in the water cistern F.
Pipes or passages G and G2 are provided to connect the upper part of each of the
generators with the lower part of the other consequently when these passages are
open and when one generator is exhausted and the passage between it and the
other generator is open the water from the first generator flows down this passage
into the second generator and the generation of gas is continued.
Four way cocks H, H2 are preferably fitted to control the passages C and G
and C and G2 as well as the waste outlets J, J².
Two coils D3 and D may be used and to prevent the communication by the gas
passages between the two generators I introduce the closed vessel or chamber K
containing mercury K². Pipes L, L from the top of the coils dip down into the
mercury sufficiently to form a seal and the gas delivery pipe M passes out of the
top of the vessel K. A pipe N may be provided to drain condensed water out of K.
Instead of two coils gas passages from the generators may pass straight up from
the generators and then down again into the mercury in this case the pipe M may
be made into a cooling coil.
More than two generators may be arranged in this way.
To prevent the full charges of the generators being acted upon at once that is
to say: enable comparatively small quantities of calcium carbide to be acted upon,
I may use a number of small generators coupled together by passages connecting
the upper end of the first generator to the bottom of the second generator and the
top of the second generator to the bottom of the third and so on. By this means
when the first generator is exhausted the water flows from it into the second and
so on through the series. Two generators only may be coupled in this way.

I, JOHN HENRY EXLEY, of Byram Street, Huddersfield, in the County of York,
Merchant, 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 apparatus for manufacturing acetylene
gas and particularly to that class of apparatus in which two or more generators are
used, and its primary object is to enable the second generator to be automatically
brought into operation when the first is exhausted.
To fully describe my invention reference is made to the accompanying sheet of
drawings in which similar letters of reference indicate corresponding parts in each
of the figures.
Figure 1, represents an elevation of an acetylene gas making apparatus fitted
with my improvements.
Figure 2, is a plan view of the same.
The generators A and A2 are mounted on each side of the holder B and the
water passages C and C³ connect them to the holder. The gas passages D and D
are both connected to the cooling coil D³ located in the water cistern F.
are provided in the gas passage.
Taps 1+
Pipes or passages G and G2 are provided to connect the upper part of each of the
generators with the lower part of the other, consequently when one generator is
exhausted and the passage between it and the other generator is open the water
from the first generator flows down this passage into the second generator and
the generation of gas is continued.
Four way cocks H and H2 are preferably fitted to control the passages C, and G
and C and G2 as well as the waste outlet J and J². For this purpose one way a of
the cock H is permanently connected to the generator A and the cock is made with
a hollow plug so that such way is never closed, and the way b is connected to the
water supply pipe C and the way d is connected to the pipe G. The side opening
in the plug of the cock is on the same side as the handle or lever e consequently
the direction in which the handle points indicates which passage is in communica-
tion with the generator. The valve H2 is connected to the generator A³ and the
pipes C2 and G2 in a similar way.
To prevent the full charge of the generators being acted upon at once that is to
say enable comparatively small quantities of calcium carbide to be acted upon I
may use a number of small generators coupled together by passages connecting
the upper end of the first generator to the bottom of the second generator and
the top of the second generator to the bottom of the third and so on.
By this
means when the first generator is exhausted the water flows from it into the second
and so on through the series. Two generators may be coupled in this way only one
of which is connected to the holder.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what I
claim is:-
1. The combination with the generators A and A2 of the connecting pipes G
and G2 arranged substantially as herein shown and described, and for the purpose
specified.
2. In acetylene making apparatus, two or more generators, one of which is
connected to the gas holder, and the other or others coupled together by connecting

action.
