COMPLETE SPECIFICATION.
Apparatus for the Generation of Acetylene Gas.
I, EMILE FRANÇOIS JEAN CLEMENT BAUWERAERTS of 8, Rue des Princes,
Brussels, in the Kindom of Belgium, Inventor, 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 relates to an apparatus for generating acetylene gas and to a
pressure-regulating device for regulating the yield of the gas.
In the accompanying drawing which illustrates my invention :-
Figures 1, 2 and 3 are views in elevation, vertical section, and horizontal section
respectively of the generating apparatus, and
Figures 4, 5 and 6 are views in elevation, vertical section, and horizontal section
respectively of the pressure regulator or governor, and
Figures 7 and 8 are detail views.
Throughout the views similar parts are marked with like letters of reference.
The generator comprises two reservoirs A and B of steel, nickelled or enamelled
internally. These reservoirs communicate with each other at top and bottom by
means of pipes or conduits a and a¹. The lower pipe a is fitted with a cock a³, and
the two reservoirs are fitted with a discharge or blow-off b.
The reservoir A into which the material such as carbide of calcium is placed is
closed at its upper part by means of a cover c or screw-plug of very large size
which is adapted to screw into the shell of the reservoir and is provided with two
handles c'.
The removal of the cover e permits of the introduction into the reservoir, of a
pail or bucket C or other receptacle charged with carbide of calcium, and having
its external surface formed with longitudinal slots or grooves to allow of the
water passing into the receptacle so as to come into contact with the carbide.
The use of this receptacle allows of charging and discharging the reservoir
without loss of time and without cleaning.
The reservoir B which contains the water, is provided at its upper part with
stop valve e for regulating the discharge of the gas.
When the two reservoirs are charged, the one (A) with the carbide of calcium
contained in the pail C, and the other reservoir (B) with water, the cock a³ is
opened, and the water in rising up along the outer wall of the pail comes in contact
with the carbide of calcium, and acetylene gas is at once generated and evolved
which gas passes through the pipe a' into the reservoir B wherein it exerts a
pressure upon the water contained in the latter in such a manner as to render the
production of gas continuous.
On leaving the reservoir B, the acetylene gas passes to the regulator which is
fitted with a, pressure gauge that indicates the pressure in the pipes.
The regulator consists essentially of a gas bell D of conical shape designed to
accelerate the ascending movement of the gas. In this bell there is arranged a
gauge or test tube d the bottom of which is of bulging form and is perforated with
numerous apertures of suitable size, and extends down to within a small distance
of the bottom of the bell, and the top of which communicates with the pipe d¹
which starts from the top of the bell and is provided with a cock designed for
regulating once for all the pressure of the gas in the pipes.
The pipe d' is provided with an auxiliary pine or brauch
which ascends

page_text: obliquely and terminates under the disc of the valve E: The disc of the valve
rests upon three projections and through its centre there extends a tube f that is
fitted, at one end in the pipe d', and at the other end in the opening of a second
disc mounted on top of the valve. This opening has mounted over it a cap f
against which the tube f bears when the current of gas passing through the branch
pipe d, lifts the disc of the valve up entirely.
The tube has one or more apertures above the said disc in order to allow
the gas to escape to the right and to the left of the cap f1, when the valve is
entirely lifted.
The branch pipe d² in combination with the valve ensures uniformity of pressure
in the pipes.
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.) An apparatus for generating acetylene gas characterized by:-First a
generator consisting of two reservoirs communicating with each other, for generating
the gas in a continuous and adjustable manner; Secondly a pressure regulator
having a pressure gauge in front of it and comprising a bell provided with an inner
'perforated gauge or test tube, a cock, a branch pipe, and a valve composed of two
dises connected together by means of a tubular piece substantially as hereinbefore
'described and illustrated in the accompanying drawing.
(2.) A generator of acetylene gas, characterized by two reservoirs of suitable
material, of which the one contains the gas generating material in a receptacle, and
.the other contains water, the two reservoirs communicating with each other at the
'top and bottom, the lower communication which serves for allowing the water to
enter into contact with the aforesaid material, being provided with an interrupting
device, the arrangement being such that the gas generated and given off in the
reservoir that contains the gas generating material, is stored up or collects in the
upper part of the reservoir that contains the water and therefore acts with its own
pressure upon the said water so as to render the generation of gas continuous, the
water reservoir being furnished with a stop valve for regulating the discharge of
the gas substantially as herein before described and illustrated in the accompanying
drawing.
(3.) A pressure regulating device having a pressure gauge in front of or before
it, and being characterized by a bell of conical form for promoting the ascending
motion of the gas, and containing or enclosing a perforated gauge or test tube
leading to a cock for adjusting the pressure once for all, a branch pipe connected
to the main pipe and designed to lift the lower disc of the valve, a valve comprising
two discs, the lower one of which is provided with supports and is pierced by a
pipe that is furnished with orifices above the disc, the said pipe being fitted in the
upper disc that is provided with a cap having lateral openings, the combination of
this valve with the double pipe enabling regulation or adjustment of the discharge
to be effected and thus ensure uniform pressure in the pipes substantially as
herein before described and illustrated in the accompanying drawings.
