Improvements in Acetylene Generators and Holders.
We, JOHN AYKROYD and BARNARD AYKROYD, both of Cullingworth, near
Bradford, in the County of York, Plumbers, do hereby declare the nature of this
invention to be as follows:-
This invention more particularly relates to the apparatus for making and
storing acetylene for which Letters Patent No. 16344 were granted to us dated
the 10th July 1897, and its object is to simplify the means of supplying the
generator with water.
For this purpose we secure to the side of the water holder in which the gas
holder rises and falls a vessel of cylindrical or other suitable form reaching to
the top or there abouts and extending down a suitable distance. This vessel is
closed at both ends and its lower end is connected by a water pipe to the water
holder a suitable distance below. The the generators are also connected by a
water supply pipe to the cylinder but this latter pipe extends up to within
a suitable distance from the top of the cylinder. A gas supply pipe from the
gas chamber beneath the water holder is connected to the said vessel and opens
into it quite close to the top. When the gas holder rises the pressure of gas
is sufficient to press the water in said vessel below the level of the generator
supply pipe and thus stop the supply of water to the generator until the gas
holder again falls.
Dated this 28th day of September 1899.

Improvements in Acetylene. Generators and Holders.
We, JOHN AYKROYD and BARNARD AYKROYD, both of Cullingworth, neat
Bradford, in the County of York, Plumbers, 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 more particularly relates to the apparatus for making and
storing acetylene for which Letters Patent No. 16344 were granted to us dated
the 10th day of July 1897, and its object is to simplify the means of supplying the
generator with water.
For this purpose we secure to the side of the water holder in which the gas
holder rises and falls a vessel of cylindrical or other suitable form reaching to

page_text: the top or thereabouts and extending down a suitable distance. This vessel is
closed at both ends and its lower end is connected by a water pipe to the water
holder a suitable distance below. The generators are also connected by a
water supply pipe to the cylinder but this latter pipe extends up to within
a suitable distance from the top of the cylinder. A gas supply pipe from the
gas chamber beneath the water holder is connected to the said vessel and opens
into it quite close to the top. When the gas holder rises the pressure of gas
is sufficient to press the water in said vessel below the level of the generator
supply pipe and thus stop the supply of water to the generator until the gas
holder again falls.
To fully describe our invention, reference is made to the accompanying
drawing which represents an elevation of such parts of the apparatus described
in the Specification of the above cited Letters Patent as are necessary to illus-
trate our present improvements.
The upper water holder A and the lower water holder or gas chamber B
divided by the partition C are the same as described in the above cited specifica-
tion as also are the generators E and the gas pipes H and water pipes L.
The water pipes L are connected to and are solely supplied by the pipe 2.
extending up through the bottom of the cylinder 3 to a little distance from the
top. The cylinder 3 is fixed outside the water holder A and is connected to it
near the bottom by the passage 5. A gas pipe 6 from the gas chamber B
extends to near the top of the cylinder and connects the chamber and cylinder.
When the gas in the chamber B is becoming exhausted the pressure of the
gas in the cylinder 3 is correspondingly reduced therefore the water is free to flow
into the cylinder from A by the passage 5 until it rises above the water pipe 2
allowing it to flow down such pipe into the generators and more gas is generated.
As however the gas pressure in B again increases by the entry of sufficient
gas the pressure in 3 increases to the same degree and forces the water in 3 below
the level of the top of the pipe 2.
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:-
The combination with the water holder A and gas chamber B, of the vessel 3
connected to A fitted with a water supply pipe 2 and a gas pipe 6 all arranged
and operating substantially as herein shown and described.
