PROVISIONAL SPECIFICATION.
Improvements in Apparatus employed in the Production of
Acetylene Gas.
I, FRANCIS GOULDING, of Delph Road Brass Works, Great Harwood, in the
County of Lancaster, Brass-founder, do hereby declare the nature of this inven-
tion to be as follows:-
My invention has for its object an arrangement of apparatus whereby water
for the purpose of decomposing the calcium carbide in the production of acetylene
gas may be supplied automatically so as to correspond with the quantity of gas
for the time being being consumed. The requisite automatic action according
to my invention depends upon the rising and falling of the upper or bell portion
of an ordinary form of telescopic gasholder that is to say when the bell is up the
water supply is stopped and when down water is admitted into the generating
chamber.
In carrying out my said invention I attach to the outer end of an arm project-
ing horizontally from the upper part of the gasholder bell the top end of a
vertically disposed pipe which passes or slides through a stuffing box in the
bottom of a cistern containing water automatically supplied thereto through an
ordinary ball tap the vertical pipe being continued downwardly so as to enter a
stand pipe of somewhat larger diameter and open to the outer air at its upper end.
The vertical pipe has a small hole drilled into it the hole being so placed that
when the gasholder bell drops the hole sinks below the water level in the cistern
and so admits water into the pipe to find its way into the generating chamber
but when the supply of gas in the holder causes the bell to rise so as to raise the
small hole in the pipe above water level the supply of water to the calcium carbide
is stopped and the generation of the gas ceases until water is again admitted to
the generator by the lowering of the gasholder bell. The stand pipe into which the
vertical sliding pipe from the water cistern is introduced communicates with the
interior of the generator a back pressure valve being employed for the purpose of
preventing the escape of the gas from the generating chamber into the water pipes.
The generator may be of the usual or any other convenient kind and suitable
valves tubes or pipes may be employed in connection with the conveyance of the
gas to and from the gasholder.

My invention has for its object an arrangement of apparatus whereby water
for the
purpose of decomposing the calcium carbide in the production of acetylene
gas may be supplied automatically so as to correspond with the quantity of gas
for the time being being consumed. The requisite automatic action according
to my invention depends upon the rising and falling of the upper or bell portion
of an ordinary form of telescopic gasholder. that is to say when the bell is up the
water supply is stopped and when down water is admitted into the generating
chamber, as I shall now describe with reference to
ence to the accompanying diagrammatic
drawing.

In carrying out my said, invention. I attach to the outer end of an arm .1; pro-
jecting horizontally from the upper part of the gasholder bell 2, the top end of a
vertically disposed pipe 3, which passes or slides through a stuffing box 4, in the
bottom of a cistern 5, containing water automatically supplied thereto through an
ordinary ball tap 5, the vertical pipe 3 being continued downwardly so as to
enter a stand pipe 6, of somewhat larger diameter and open to the outer air at its
upper end. The vertical pipe 3 has a small hole 3 drilled into it, the hole being
so placed that when the gasholder bell 2 drops, the hole 3, sinks below the water
level in the cistern and so admits water into the pipe 6 to find its way into the
generating chamber 7, but when the supply of gas in the holder causes the bell 2
to rise so as to raise the small hole 3 in the pipe 3 above water level; the supply
of water to the calcium carbide in the generating chamber 7 is stopped and the
generation of the gas ceases until water is again admitted to the generator by the
lowering of the gasholder bell. The, stand pipe 6 into which the vertical sliding
pipe 3 from the water cistern is introduced communicates with the interior of the
generator, a back pressure valve 8 being employed for the purpose of preventing
the escape of the gas from the generating chamber 7, into the water pipes 3 & 6.
The generator may be of the usual or any other convenient kind, and suitable
valves, tubes or pipes may be employed in connection with the conveyance of the
gas, to and from the gasholder 2.

Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
+T
In apparatus for the production of acetylene gas, the combination with a teles-
copic gas-holder and a cistern containing water, of a perforated pipe. in com-
munication with the said cistern so arranged that when the upper or bell part of
the, gas-holder. falls or descends, water from the cistern is admitted to a chamber
containing calcium carbide, and when the bell rises beyond a certain height the
supply of water to the said chamber is stopped, substantially, as, herein described.
