Aberdeen, do hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved method for the regulation of the
water which dissolves the carbide of calcium in the generators and in the arrange-
ment of these generators & containers the gas which is evolved in the generator
a portion of which is made to act on the surface of the water under a fixed pressure
in a sight feed glass or other vessel which communicates with a
separate water container is so arranged that when the fixed pressure
is reached in the generator the same pressure makes the water sink in the sight
feed vessel below the exit feed pipe and causes it to flow back into the water
container and stops the flow of the water on the carbide the surplus gas passing
into the gas container to be used when required and immediately when the pressure
is relieved by gas being used water again rises in the feed vessel and flows into the
generator making more gas. An important feature of this invention being that
the generators can be placed at any distance away from the gas holders. The
generators are so arranged that fresh charges of carbide can be supplied while the
apparatus is in operation.

WILLIAM WALKER.
Acetylene Gas Generators and Containers.
WILLIAM WALKER, Copper, Brass & Tinplate Worker, 26/28, Netherkirkgate,
Aberdeen, N.B., 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:
a
This invention relates to a new or improved method for the regulation of the
water which dissolves the carbide of calcium in the generator & in the arrange-
ment of these generators & containers. The gas which is evolved in the generator,
a portion of which is made to act on the surface of the water under a fixed pressure
in a sight feed glass or other vessel which communicates with
separate water container is so arranged that when the fixed pressure
is reached in the generator the same pressure makes the water sink in the sight
feed vessel below the exit feed pipe & causes it to flow back into the water
container & stops the flow of the water on the carbide, the surplus gas passing
into the gas container to be used when required & immediately when the pressure

is relieved by gas being used, water again rises in feed vessel & flows into the
generator, making more gas. An important feature of this invention being that
the generators can be placed at any distance away from the gas holders. The
generators are so arranged that fresh charges of carbide can be supplied while the
apparatus is in operation.
In the accompanying drawings
Figure 1, is an elevation of the apparatus showing its water container W.
Sight feed vessel B with piping generators H, and H 1, & separate gas holder K.
Fig. 2, is a plan of same apparatus.
The action of the apparatus is as follows. Water being placed in the con-
tainer W, and in the gas-holder K, up to M, all the stop cocks being opened; water
flows down pipe C, into vessel B, at its lower end, and rises up to out let pipe D,
& flows into generator H, which has been previously charged with carbide of
calcium gas being formed--passes out by pipe G, and into tank K, displacing the
water by making it flow out by chamber L, on to the top of centre division of
tank M, and whenever the pressure of the gas, becomes greater than the weight of
the head of water in the container W, owing to displacement of the water from
tank K, the water in vessel B, by the pressure of the gas through the branch
pipo I, sinks below the out let pipe D, and ceases to flow on to the carbide-
stopping the making of gas. After the pressure is relieved by burning or other-
wise, the water in the container W, again rises in vessel B & flows on to the
carbide making more gas, making the action automatic & continuous. After all
the carbide is dissolved in H, water rises up to out let D1, and flowing on to
the carbide in generator H1, when the stop cocks E, and F, can be shut and a
new charge of carbide, put in to generator H, to be used when required. When-
ever the pressure throughout the system becomes greater than the weight of the
head of feed water pipe, C, becomes a relief pipe. Gas will escape out through
the water in the container W.
The generators H and H1, may be arranged at any distance away from the
gas holder K, without any undue pressure being in the generators or pipes as the
gas pressure entirely depends on the height of feed water which can be raised to
suit circumstances.
Having now ascertained the nature of my said invention and in what manner
the same is to be performed, I declare that, what I claim is as follows:-
First. Sight feed or other vessel for automatically regulating the supply of feed
water to the generators by the gas pressure independent of either cocks, valves,
levers, chains, or other mechanical devices, all as shown and described.
Second. The arrangement of placing the tanks at any distance from the gas
holder as described.
Third. Making the water container and pipe act as a relief escape or safety
valve as described.
