I, PAUL MARGULIES, of 13, Tiraspolskaja, Odessa, in the Empire of Russia,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an acetylene gas generator having two closed gas
holders and which is provided with two automatic regulating devices, one of
which regulates the supply of the water to the carbide whilst the other cuts
off all communication with one of the gas holders when the pressure of the
gas reaches a predetermined amount, so that the gas subsequently produced
Hows into one of the gas-holders only, in order to obviate the prejudicial effects
upon the character of the illuminations which are caused by an overproduction
of gas.
In adapting my improved apparatus for use in railway carriages the gas
generator is suspended in a frame beneath the carriage flooring and is pivotally
mounted in this frame by means of two pins. The generator is caused to form
a tight joint by means of the screw bolt.
In the constructional form of apparatus adapted for dwellings or the like,
the generator may be disconnected by unscrewing two nuts and it is hermetically
closed by means of cocks and thumb screws. I provide two automatically
regulated valves one of which regulates the supply of water from the water
reservoir to the generator whilst the other regulates the flow of the gas which
has been produced to the gas-holder. These valves consist of a socket within a
cylinder a rod which is divided into two portions, this rod is displaced in an
exactly vertical direction, guided by balls; upon the lower extremity of this
rod a weight is arranged by means of an elastic membrane, whilst its upper
extremity is connected with the key of a controlling cock in a casing on the
said valve. Upon the displacement of the rod the said cock is closed or opened
as the case may be. By means of a nut the length of the divided rod may be
varied and with it the effective aperture of the said controlling cock. Of the
two tightly closed gas holders one serves for directly supplying the burners.
The operation of the apparatus adapted for railway carriages is as follows:
Upon unscrewing the bolt the generator descends and oscillates upon its pivots
to an extent sufficient to permit of its being filled with carbide, whereupon
it may again be hermetically sealed by screwing up the said bolt. In the form
of apparatus adapted for dwelling houses or the like the generator may be
removed by unscrewing the nuts and charged with carbide outside the house,
it being hermetically closed by tightening up the thumb screws and closing the
cocks on the generator.
After the reservoir has been filled with water the water reservoir cock is
opened, and also the cocks to the generator. The water flows through the pipes
and the controlling cock in the casing into the carbide vessel. The gas produced
rises through the pipes under the first valve hereinbefore mentioned into the

page_text: first gas holder and at the same time also into the second gas holder through
the controlling cock of the second valve which cock is normally open. If the
pressure of the gas should exceed the normal, the gas immediately causes the
rod to rise in the first valve and so closes the cock, thereby interrupting the
flow of water from the reservoir; at the same time the gas passes from the second
holder under the second valve raises the rod and closes the passage for the gas
through the said valve, so that any gas subsequently generated within the
generator is able to reach the first gas holder only. If the pressure in the
second gas-holder should fall below the normal, the rod with its weight will
descend within the valve and the gas will flow from the first gas-holder into the
second gas-holder. In addition to this, when the pressure of the gas falls below
the normal in the first holder, the rod immediately falls within the first valvo
and the cock is opened for the passage of water from the reservoir to the generator
the normal in the first holder, the rod immediately falls within the first valve
so that fresh gas is produced.
I, PAUL MARGULIES, of 13, Tiraspolskaja, Odessa, in the Empire of Russia,
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:-
.
This invention relates to an acetylene gas generator having two closed gas
holders and which is provided with two automatic regulating devices, one of
which regulates the supply of the water to the carbide whilst the other cuts
off all communication with one of the gas holders when the pressure of the
gas reaches a predetermined amount, so that the gas subsequently produced
Hows into one of the gas-holders only, in order to obviate the prejudicial effects
upon the character of the illumination which are caused by an overproduction
of gas.
My invention is illustrated in the accompanying drawing in which:
Figure 1 is an arrangement of an acetylene gas generator in accordance with
this invention, adapted for use in railway vehicles, and
Figure 2 represents an apparatus in accordance with this invention adapted
to dwelling-houses.
In adapting my improved apparatus for use in railway carriages the gas
generator A is shewn suspended in a frame n¹ n¹ beneath the carriage flooring
and is pivotally mounted in this frame by means of two pins e e.
The generator.
is caused to form a tight joint by means of the screw bolt 1.
In the constructional form of apparatus adapted for dwellings or the like
shewn in Figure 2, the generator may be disconnected by unscrewing two nuts i i
and it is hermetically closed by means of cocks wand thumb-screws d d.
I provide two automatically regulated valves V V₁ one of which V regulates the
supply of water from the water reservoir E to the generator A, whilst the other V
regulates the flow of the gas which has been produced to the gas-holder B!.
These valves V and VI are constituted by the following parts: In a socket within
a cylinder, h, a rod C which is divided into two portions, is displaced in an

page_text: exactly vertical direction, being guided by the balls cc; upon the lower
extremity of this rod a weight 7 is arranged by means of an elastic membrane p,
whilst its upper extremity is connected with the key of a controlling cock u
in the casing y. Upon the displacement of the rod C the said cock u
is closed or opened as the case may be. By means of the nut z the length. of
the divided rod C may be varied and with it the effective aperture of the said
controlling cock u. Of the two tightly closed gas holders B and B', supported
in the brackets n, one serves for directly supplying the burners. E is the water
reservoir.
The operation of the apparatus adapted for railway carriages is as follows;
Upon unscrewing the bolt I the generator A descends and oscillates upon its
pivots se to an extent sufficient to permit of its being filled with carbide, where-
upon it may again be hermetically sealed by screwing up the said bolt I. In
the form of apparatus adapted for dwelling houses or the like (Figure 2), the
generator A may he removed by unscrewing the nuts ii and charged with carbide
outside the house, it being hermetically closed by tightening up the thumb
screws d d d and closing the cocks and w³.
After the reservoir E has been filled with water, the cock w² is opened, and
also the cocks and to. The water flows through the pipes a a and the con-
trolling cock u in the casing y into the carbide vessel A. The gas produced
rises through the pipes kk under the first herein before mentioned valve into
the first gas-holder B, and at the same time also into the second gas holder B¹
through the controlling cock of the valve V, which cock is normally open. If
the pressure of the gas should exceed the normal, the gas immediately causes
the rod C to rise in the valve V and so closes the cock u thereby interrupting the
flow of water from the reservoir E; at the same time the gas passes from the
second holder B' under the valve Vi, raises the rod C and closes the passage for
the gas through the said valve VI, so that any gas subsequently generated within
the generator A is able to reach the first gas holder B only. If the pressure
in the second gas-holder B¹ should fall below the normal, the rod C with its
weight will descend within the valve V and the gas will flow from the first
gas-holder B into the second gas-holder B. In addition to this, when the
pressure of the gas falls below the normal in the holder B, the rod C immediately
falls within the valve V and the cock is opened for the passage of water from
the reservoir E to the generator A, so that fresh gas is produced.
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. An acetylene gas generator characterized by two gas-holders (B B'), one
of which is connected with the burners and is automatically closed, if the pressure
of gas exceeds the normal, while the other receives the gas subsequently produced,
for the purpose of obviating the prejudicial effects upon the character of the
illuminations which are caused by an overproduction of gas.
2. In acetylene gas generators the combination of two gas-holders, one of
which is connected with the burners and is automatically closed, if the pressure
of gas exceeds the normal while the other receives the gas subsequently pro-
duced, of two equal automatically regulating devices (V VI), one of which
regulates the supply of the water to the carbide whilst the other cuts off all
communication with the gas-holder connected with the burners, when the pressure
of gas reaches a predetermined amount, both regulating devices are at the same
time automatically operated to open their valves when the pressure of gas in
the two holders falls below the normal.
3. In acetylene gas generators the combination of two gas-holders, one of
which is connected with the burners and is automatically closed when the pressure
of gas exceeds the normal while the other receives the gas subsequently produced,
of two equal automatically regulating devices, one of which regulates the supply

page_text: of water to the carbide, whilst the other cuts off all communication with the
gas-holder connected with the burners, when the pressure reaches a predetermined
amount, and of a frame for supporting and attaching the generator beneath the
flooring of a railway carriage in such a manner that the generator may be removed
or tilted on pivots for the purpose of filling or cleaning.
