Improvements in Apparatus for Generating Acetylene Gas.
I, GEORGE WILLIAM EMMERSON, of 16, St. Nicholas Churchyard, Newcastle-on-
Tyne, in the County of Northumberland, Drysalter, do hereby declare the nature
of this invention to be as follows;
This invention relates to improvements in apparatus for generating acetylene
gas. The apparatus consists of three principal parts, viz., water tank, gas holder,
and generator. The tank preferably stands over or rests upon and may be firmly
connected to the generator; the gas holder rises and falls in the tank. The
generator is provided with a tray or trays for holding the carbide and with suit-
able doors for introducing the carbide and for cleaning. The space below the
traps is filled with water supplied from the tank by means of a pipe on which is a
regulating or controlling valve or cock. A pipe conveys the gas from the top
of the generator into the holder, the top of the pipe being higher than the water
level in the tank. A weighted valve is fitted in the top of the pipe and provided
with a lever acting opposite the weight. When the holder is empty or nearly
empty the top of it or some part or projection of it presses on the lever and
opens the valve, permitting gas to pass from the generator into the holder. As
the gas enters, the holder will rise the pressure on the lever will be gradually
relieved and the valve will close. If the gas continues to be generated in the
generator the pressure will gradually force back the water from the carbide
through the supply pipe into the tank until equilibrium be established and.
generation of gas will have ceased. When the gas in the holder has been used,
the holder will fall and open the valve at top of communicating pipe, the pressure.
in the generator will be released and the water again flow into the generator
through the supply pipe to act on the carbide. The gas is cooled by being brought
in a pipe through the water in the tank and out at or near the bottom of the
tank. In place of one generator beneath the tank, two or more may be grouped,
and one or more may be used at once.

Improvements in Apparatus for Generating Acetylene Gas.
I, GEORGE WILLIAM EMMERSON, of 16, St. Nicholas Churchyard, Newcastle-on-
Tyne, in the County of Northumberland, Drysalter, do hereby declare the nature
[Price 8d.]

page_text: of this invention and in what manner the same is to be performed to be par-
ticularly described and ascertained in and by the following statement:-
This invention relates to improvements in apparatus for generating acetylene
gas.
The apparatus consists of three principal parts, namely water tank, gas
holder, and generator or generators. The tank preferably stands over or rests
upon and may be firmly connected to the generator or generators, the gas holder
rises and falls in the tank. Each generator is provided with a tray or trays for
holding the carbide and with suitable door or doors for introducing the carbide
and for access for purposes of cleaning. The space below the trays is filled with
water supplied from the tank by means of a pipe or pipes on each of which is a
regulating or controlling valve or cock. A pipe conveys the gas from the top
of the or each generator into the holder, the top of the pipe being higher than
the water level in the tank. A weighted or spring controlled valve is fitted in
the top of the pipe. When the holder is empty or nearly empty the top of it or
some part or projection of it presses on the lever or projecting part of the weighted
or spring controlled valve and opens the valve permitting gas to pass from the
generator into the holder. As the gas enters, the holder will rise, the pressure on
the lever or valve spring will be gradually relieved and the valve will close. If
the gas continues to be generated in the generator the pressure will gradually
force back the water from the carbide through the supply pipe and through the
water (thereby purifying the gas) into the tank until equilibrium be established
and generation of gas will have ceased. When the gas in the holder has been
used,, the holder will fall and open the valve at the top of the communicating
pipe the pressure in the generator will be relieved, and the water again flow into
the generator through the supply pipe to act on the carbide. The gas is cooled
by being brought in a pipe through the water in the tank and out at or near
the bottom of the tank. In place of one generator beneath the tank, two or
more may be grouped, and one or more may be used at one time.
Before the generator is charged with carbide the part under the tray is filled
with water thus displacing air from that part of the generator. After charging
and admitting the water to the carbide the first contents of the holder will be gas
mixed with a large proportion of air. When the holder has risen a short distance
this mixture should be discharged into the atmosphere thus ensuring pure gas
in the holder the gas is kept cool by always being in contact with water.
In order that this invention may be more readily performed the annexed draw-
ings illustrate more particularly the construction.
Fig. 1 is a sectional elevation showing an apparatus having two generators
grouped beneath one tank; the generators can be used together or singly. Fig. 2
is an elevation at right angles to Fig. 1.
a is the holder, b the tank, c the generator case, d and are the upper com-
partments of the generators and e e¹ the lower compartments thereof. f f are
trays of perforated plate or wire gauze for holding the carbide, 9 is the door of
generator and h a screw bolt working in a bridge held by lugs k on casing c,
for firmly closing the said door g, 1 is a draw off cock or valve from the generator,
m and m water supply pipes from the tank 6 to the generators, non stop cocks

generators to the holder a. p and are spring valves closing the tops of
pipes o and o¹. q is the pipe for conveying gas to points of consumption, stop

Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is:
1. In apparatus for generating acetylene, the combination of the generator e in
one
OP more separate compartments with the tonk- }

for passage of water to the lower part of the generator and one or more pipes 001
for passage of gas from the upper part of the generator to the holder said pipe or
pipes having each a valve closable by weight, spring, or equivalent pressure
and adapted to be opened by the holder or some projecting or other part thereof
when the latter is in or near its lowest position, the whole operating substantially
in the manner herein described.
2. Apparatus for generating acetylene of the nature substantially as described
in Claim and constructed substantially in the manner herein described and
illustrated in the drawings.
