Improvements in Apparatus for Generating 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 that type of apparatus for manu-
facturing acetylene gas in which two or more generators are arranged in conjunction
with one holder or receiver and are adapted to be automatically fed with water
therefrom, and the object of the invention is to automatically bring the second
generator into operation when the first is exhausted.
For this purpose I place the water passage from the holder to one of the
generators at a suitably higher altitude than the water passage from the holder
to the other generator consequently if the generator communicating with the holder
by the lower passage is first put into operation so as to lower the level of the
water in the holder below the level of the passage therefrom to the other generator
the latter passage may then be opened and the generator in connection with it will
be automatically brought into operation as soon as the first generator is practically
exhausted and the consumption of gas allows the water in the holder to rise high
enough to flow into the second generator.
Each generator is preferably provided with two water passages from the holder
one above the other and the upper passage preferably joins the lower passage
before the latter reaches the generator. Each passage is fitted with a stop valve
or tap so that each generator may be put into communication with the holder by
either its higher or lower passage as may be required. A third stop valve may
be fitted to each generator between the junction of the two passages and the
generator so that both passages may be stopped thereby.
'
The vertical or inclined portions of the upper passages above their connection
with the lower passages are preferably made of glass tubing to form water gauges.
A suitable float may be placed in each of the gauges adapted to readily indicate
the height of the water therein.
To prevent the gas passing from one generator to the other the gas passages
from the generators if joined together are each fitted with a check valve
adapted to allow gas to readily pass from each generator to the holder but not in
the reverse direction.

Improvements in Apparatus for Generating Acetylene Gas.
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 that type of apparatus for manu-

page_text: facturing acetylene gas in which two or more generators are arranged in
conjunction with one gas holder or receiver and are adapted to be automatically
fed with water therefrom as for instance, the apparatus for which I have obtained
Letters Patent No. 12,344 dated 26th June 1895, and the object of the invention
is to automatically bring the second generator into operation when the first is
exhausted.
For this purpose I place the water passage from the holder to .one of the
generators at suitably higher altitude than the water passage from the holder
to the other generator consequently if the generator communicating with the
holder by the lower passage is first.put into operation, so as to lower the level of
the water in the holder below the level of the passage therefrom to the other
generator the latter passage may, then be opened and the generator in connection
with it. will be automatically brought into operation as soon as the first generator
is practically exhausted. and, the consumption of gas, allows the water in the holder
to rise high enough to flow into.the second generator.
Each generator is preferably provided, with. two water passages from the holder
one above the other and, the upper passage, preferably joins the lower passage
before. the latter reaches, the generator. Each passage is fitted with a stop valve
or a tap so that each generator may be put into communication with the holder
by either, its higher or lower passage as may be required.
Reference is to be had to the accompanying sheet, of, drawings forming a part
of this specification, in which similar letters of reference indicate corresponding
parts in each of the figures.
Figure 1, represents an elevation of such parts of an acetylene gas apparatus as
are necessary to illustrate my improvements.
Figure 2, represents a plan view of the same.
"
The holder A and the water cistern, B and the generators F and F.2 are of the
samo.construction as that described in the specification of my above cited.Letters
Patent. The water passages Hand H4 are each connected to the "tee
piece H.5 coupled to, the holder A and are each fitted with, a tap H.2. Branch
pipes H 6, H-7 are respectively connected.to, the pipes, H and H4 between the
taps H2 and the generators. These branch pipes are fitted with stop taps H 8
and are coupled to the "tee" piece H 9 connected to the holder A at a suitably
higher level than the "tee". picce H 5.
Assuming both generators to be charged to put them into operation it is simply
necessary to open say the tap H 2 in the passage H which allows water to flow
into the generator F and the gas generated passes into the holder and more.or
less displaces the water therein. When the water has been displaced below the
level of the connection H 9, the tap H8 in the branch pipe H 7 may be opened so
that when the generator F is exhausted sufficiently to allow the water again to
rise in the holder above the level of H 9 the water will flow by the branch pipe H 7
into the generator F 2 which will be automatically brought into operation. When
completely exhausted the first generator may be shut off from the holder and be
recharged without stopping the other generator.
To facilitate this the gas passages G are carried up over the top of the
cistern B and are both connected by the pipe G 3 to the holder and each
pipe is fitted with a check valve G 4 adapted to allow gas to pass towards the
holder but not in the reverse direction. One of these check valves is shown in
section in Figure 1.
4.
Three-way taps may be used instead of the pairs of taps H 2 and H 8.
Having now particularly described and, ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what I
claim is :
t

page_text: 2. The combination with acetylene gas apparatus of the type specified, of
cwo check valves G 4 in the gas passages, substantially as herein shown and
described.
