I, JULES KREMER, of Gilly (Charleroi) in the Kingdom of Belgium, Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to acetylene gas generators in which the carbide in a state
of powder, or in small pieces, is automatically distributed in the liquid contained
in the generator. In most of these generators the distribution of the carbide is
effected by means of a cone adapted to more or less close the aperture of a
hopper containing the carbide; when the pressure decreases the cone, descending
with the gas holder, uncovers the aperture of the hopper and allows a certain
quantity of carbide to fall into the liquid; the acetylene gas becomes disengaged,
causes the gas holder to rise and, thereby, the aperture of the hopper to be again
closed. As, however, the extent of movement of the gas holder is limited by
the closing of the aperture of the distributing hopper, and so long as this closing
is not effected more or less carbide can fall into the liquid, the production of gas
does not cease instantaneously with the cessation of the upward movement of the
gas holder and, consequently, with the closing of the hopper; the production of
the gas on the contrary continues for some moments and the gas holder, not
being able to rise, the gas becomes compressed, the result of which is that a
continual variation of pressure is caused in the generator.
In most of these generators, moreover, the charge of carbide rests upon the
gas holder, which is the cause of a further variation of pressure, the weight of the
holder thus continually varying with the quantity of carbide contained in the
hopper and, consequently, it cannot be equilibrated at any time during the working.
The object of my invention is to remedy these defects and to allow of main-
taining a constant pressure in the generator by a peculiar arrangement of stopper
which, in combination with the gas holder, allows the latter to stop the fall of
the carbide into the liquid at the proper moment without, however, it being
limited in its upward movement which can, consequently, be continued in propor-
tion to the quantity of gas produced after the stoppage of the hopper. My
invention further consists in the arrangement of the distributing hopper in the
generator itself in such a manner as to render the gas holder quite independent
of the quantity of carbide which the hopper may contain, and in the employment
of suitable means for facilitating the renewal of the charge of carbide while the
apparatus is at work, and the fall of the carbide through the aperture of the
distributing hopper.
The outer receptacle containing the liquid for effecting the decomposition of
the carbide is provided in its interior with a support to which is fixed the hopper
containing the carbide.
In the said receptacle moves the gas holder equilibrated by counter-weights
and carrying a vessel which allows, even while the apparatus is at work, of
renewing the supply of carbide to the hopper by simply operating a cock.
The end of the tube conducting the carbide into the hopper is provided with
springs forming clips which, moving with the gas holder, have for object to push

page_text: the carbide towards the aperture of the hopper and to facilitate its fall through
the said aperture.
The holder is provided with a cross bar supporting a sieve into which falls the
carbide coming from the hopper through the aperture. The closing of the
aperture is effected by means of a cylindrical rod pointed at its end in order to
facilitate its entrance into the aperture.
As will be readily understood, owing to the employment of this rod which is
adapted to slide easily between the edges of the aperture the upward movement
of the holder is not arrested until it arrives at the top of its course; when a
sufficient quantity of carbide has fallen into the liquid in the receptacle, the
holder rises and the rod entering the aperture stops the fall of the carbide. The
production of gas continuing, the holder can still continue to rise: when, through
the consumption of gas, the pressure diminishes the holder again descends, keeping
the pressure constant up to a limit determined by the length of the rod which
at this moment again uncovers the aperture, thus allowing a fresh quantity of
carbide to fall into the liquid.
The varying weight of the carbide being carried by the hopper independent of
the holder prevents any variation in the weight of the holder, and this also
contributes in a large degree to maintaining a perfectly constant pressure.

I, JULES KREMER, of Gilly (Charleroi) in the Kingdom of Belgium, Engineer,
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:-
My invention relates to acetylene gas generators in which the carbide in a state
of powder, or in small pieces, is automatically distributed in the liquid contained
in the generator. In most of these generators the distribution of the carbide is
effected by means of a cone adapted to more or less close the aperture of a
hopper containing the carbide; when the pressure decreases the cone, descending
with the gas holder, uncovers the aperture of the hopper and allows a certain
quantity of carbide to fall into the liquid; the acetylene gas becomes disengaged,
causes the gas holder to rise and, thereby, the aperture of the hopper to be again
closed. As, however, the extent of movement of the gas holder is limited by
the closing of the aperture of the distributing hopper, and so long as this closing
is not effected more or less carbide can fall into the liquid, the production of gas
does not cease instantaneously with the cessation of the upward movement of the
gas holder and, consequently, with the closing of the hopper; the production of
the gas, on the contrary, continues for some moments and the gas holder, not
being able to rise, the gas becomes compressed, the result of which is that a
continual variation of pressure is caused in the generator.
In most of these generators, moreover, the charge of carbide rests upon the
gas holder, which is the cause of a further variation of pressure; the weight of
the holder thus continually varies with the quantity of carbide contained in the
hopper and consequently, it cannot be equilibrated at any moment during the working.

page_text: The object of my invention is to remedy these defects and to allow of main-
taining a constant pressure in the generator by a peculiar arrangement of stopper
which, in combination with the gas holder, allows the latter to stop the fall of
the carbide into the liquid at the proper moment without, however, it being
limited in its upward movement which can, consequently, be continued in propor-
tion to the quantity of gas produced after the stoppage of the hopper. My
invention further consists in the arrangement of the distributing hopper in the
generator itself in such a manner as to render the gas holder quite independent
of the quantity of carbide which the hopper may contain, and in the employment
of suitable means for facilitating the renewal of the charge of carbide while the
apparatus is at work, and the fall of the carbide through the aperture of the
distributing hopper.
The accompanying drawing is a vertical section of an acetylene gas generator
of the kind herein before referred to provided with my improvements.
The outer receptacle A containing the liquid for effecting the decomposition
of the carbide is provided in its interior with a support B to which is fixed the
hopper C containing the carbide.
In the said receptacle A moves the gas holder D equilibrated by counter-
weights P and carrying a vessel K which allows, even while the apparatus is at
work, of renewing the supply of carbide to the hopper C by simply operating a
cock r.
The end of the tube 1 conducting the carbide into the hopper C is provided
with springs S forming clips which, moving with the gas holder, have for object
to push the carbide towards the aperture o of the hopper C and to facilitate its
fall through the said aperture.
The gas holder ID is provided with a. cross bar E supporting a sieve F into
which falls the carbide coming from the hopper C through the aperture o.
The
closing of the aperture o is effected by means of a cylindrical rod T pointed at its
end in order to facilitate its entrance into the aperture o.
As will be readily understood, owing to the employment of this rod, which is
adapted to slide easily between the edges of the aperture o, the upward movement
of the gas holder is not arrested until it arrives at the top of its course; when a
sufficient quantity of carbide has fallen into the liquid in the receptacle A, the
gas holder 1) rises and the rod T entering the aperture o stops the fall of the
carbide. The production of gas continuing, the gas holder D can still continue
to rise; when, through the consumption of gas, the pressure diminishes, the gas
holder again descends, keeping the pressure constant up to a limit determined
by the length of the rod T which at this moment again uncovers the aperture o,
thus allowing a fresh quantity of carbide to fall into the liquid.
The varying weight of the carbide being carried by the hopper C independent
of the gas holder D prevents any variation in the weight of the holder, and this
also contributes in a large degree to maintaining a perfectly constant pressure.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. In an acetylene gas generator in which the fall of the carbide, in the form
of powder or in small pieces, into the liquid is regulated through the medium
of the gas holder of the apparatus causing the stoppage of the distributing hopper,
the arrangement having for object to render the upward movement of the gas
holder independent of such stoppage and to allow it to be prolonged even after
such stoppage has taken place, and based upon the employinent, for regulating
the fall of the carbide, of a cylindrical rod of a length suitable to the extent of
movement of the gas holder and sliding easily in the aperture of the hopper
containing the carbide substantially as hereinbefore described.
2. In an acetylene gas generator provided with a cylindrical rod regulating
the fall of the carbide into the liquid for the purpose of rendering the gas holder

page_text: independent of the weight of the carbide contained in the distributing hopper,
the arrangement of the said hopper in the interior of the generator upon a suitable
support, substantially as herein before described.
3. In combination with a distributing hopper mounted in the interior of an
acetylene gas generator and independent of the gas holder of the said generator,
a vessel K arranged above the gas holder and allowing, even while the apparatus
is at work, of a fresh quantity of carbide being supplied to the distributing hopper,
substantially as set forth.
4. The combination with a distributing hopper mounted in the interior of an
acetylene gas generator of springs S following the movement of the gas holder
and acting upon the carbide contained in the distributing hopper for facilitating
the fall of the carbide through the aperture of such hopper, substantially as set
forth.
5. The improved acetylene gas generator hereinbefore described and illustrated
in the accompanying drawing.
