I, DAVID CHARLES MORENCY, a citizen of the Dominion of Canada, residing
at Levis, in the County of Levis, Province of Quebec, Canada, do hereby declare
the nature of this invention and in what manner the same is to be performed,
be particularly described and ascertained in and by the following statement :-
This invention relates to apparatus for supplying acetylene gas; and it consists
in the novel construction and combination of parts hereinafter fully described and
claimed:
The drawing shews a sectional side view of the apparatus.
A is a vessel for containing a metallic carbide a', such as the carbide of calcium,
from which acetylene gas is formed by the addition of water according to the well.
known reaction.
B is an outer vessel for holding, and B' is a gas vessel open at the bottom and
arranged over the vessel A inside the vessel B. The water in the vessel B keeps
the vessel B gas-tight. An inner wall in the vessel B keeps the water from
coming in contact with the vessel containing the carbide. A solution of chloride
of calcium or of chloride of sodium may be used instead of water, if desired, with
the advantage of not freezing so easily and of absorbing ammoniacal gas. Other
viscious liquids may also be used when necessary.
D is a flexible tube provided with a valve d for dropping water onto the carbide
of calcium.
D¹ is an outlet pipe for the gas provided with a valve d¹ and connected to the
gas vessel B¹.
A' is an escape pipe for the gas should it accumulate in the vessel B. The
pipe A' extends downward through the vessel B₁ into the water. When the
pressure in the vessel B' becomes so great that the water in it is depressed below
the bottom of the pipe A', the gas escapes up the said pipe and outside the
building.
C is the gas receiver consisting of a vessel open at the bottom and slidable
vertically in a vessel C¹ which contains water with chloride of sodium or chloride:
of calcium, or any other liquid such as oil or molasses. The pipe D¹ is connected
to the top part of the gas receiver. The height of the liquid in the vessel C' is.
indicated by the transparent tube or glass guage c. The lower part of this tube
is connected to the vessel C' and its upper part is open to the atmosphere. K is a
transparent tube or glass guage secured to the vessel C₁, and k is a flexible pipe
connecting the upper part of the tube K with the upper part of the gas receiver C.
The flexible water pipe D has a nozzle d' which projects upwardly within the
tube K. The liquid in the tube K always stands at the same height as the liquid
in the gas receiver C.
"
E is an escape pipe for the gas in the vessel C should the pressure become
excessive. This pipe extends downward through the said vessel into the water in
the vessel C¹.
E are check chains connecting the vessel C with the vessel C' so that' the
vessel C cannot be raised by the gas above a certain height.
* "
Fis an outer vessel having no top and secured to the top portion of the gas

page_text: The vessel F contains water, or other liquid, so that the vessel G is gas-tight.
H is the gas distributing pipe provided with a valve h and connected to the upper
part of the vessel G. I is a conical plug valve suspended from the top of the
vessel G by a rod or cord i, and operating to close the tube f when the vessel G
is-raised.
J is a counterbalance weight connected to a flexible connection j. This con-
nection passes over pulleys and is attached to the vessel F so that the weight of
the vessels F, G, C is balanced.
Instead of water, the vessel C¹ may contain some other liquid such as oil,
molasses etc., so as to be safer when used on cars, steamboats, or other vehicles, and
in that case I provide an additional water-vessel C₁ (shown by dotted lines on the
drawing) and the lower end of the tube K is connected to the vessel C", instead
of being connected to the vessel C¹.
The water passes from the vessel C¹ or from the vessel C" down the nozzle d'
and pipe D to the carbide, and the gas is generated in the vessel B'. The gas
passes from the vessel B₁ into the receiver C, through the valve I and into the
vessel G. When the gas enters the vessel G faster than it passes off by the pipe H
the vessel G is raised by the pressure of the gas accumulating inside it and the
valve is closed. The valve I adjusts itself automatically so that it lets the gas
pass out of the pipe H at a constant pre-arranged pressure.
When the pressure
of the gas increases in the vessel C' it depresses the water in it and in the tube K,
and as soon as the level of the water is below the top of the nozzle d' the supply
of water to the carbide is cut off automatically so that no more gas is formed.
The supply of carbide is renewed as often as necessary, and two similar gas
generators are preferably used and are connected to the gas receiver alternately so
as to produce a constant supply of gas.
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 :
1. The combination, with an outer vessel for holding a liquid, of an inner vessel
for gas open at the bottom and floating in the liquid in the aforesaid vessel, and a
gas escape passing through the said gas vessel and having its lower end arranged
below the normal surface of the water, substantially as set forth.
2. The combination, with a vessel for generating acetylene gas, of a receiver for
the gas connected to the said vessel and having a water space at its lower part,
and a pipe connecting the said water space with the said generating vessel and
supplying water for decomposing the metallic carbide until the pressure of the gas
in the receiver becomes higher than necessary, substantially as set forth.
3. The combination, with an outer vessel for holding liquid, of an inner vessel
for holding gas open at its bottom and floating in the said liquid, a tube having its
upper end connected to the inner vessel and its lower end connected to the outer
vessel, and a liquid supply pipe provided with a nozzle projecting upwardly in the
said tube, the flow of liquid through the said nozzle and tube being regulated
automatically by the pressure of the gas in the said inner vessel, substantially as
set forth.
4. The combination, with a gas receiver, of an outer vessel for holding liquid
arranged at the upper part of the said gas receiver and provided with an upwardly
projecting tube, an inner vessel open at the bottom and floating in the said liquid,
a gas distributing pipe connected to the upper part of the said inner vessel, and a
valve carried by the said inner vessel and operating to close the said tube when
the said inner vessel is raised by the pressure of the gas inside it, substantially as
set forth.
5. An apparatus for generating acetylene gas, in which the passage of the water
from the water-supplying vessel into the vessel containing the carbide is constantly

page_text: and automatically checked and controlled by the pressure of the gas itself in the
said apparatus; said pressure, when too high, causing the level of water in the
supplying pipe to descend below the opening of the nozzle ď, substantially as set
forth.
