We, LEOPOLD LEDERER and JULIUS GOTTLIEB, both of Eger, in the Empire of
Germany, Manufacturers, do hereby declare the nature of this invention to be as
follows:
The subject of the present invention is a carburetor which automatically regu-
lates the pressure of the air or of the gas before their passage through the car-
bureting material, regulating, moreover automatically the thickness of the layer
of the said material, and finally maintaining the said carbureting material at a
practically constant temperature and thus admitting of a regular and uniform
carbureting being obtained.
The apparatus comprises a casing or vat filled with water up to three quarters
of its height and in which floats a bell guided in any suitable manner against
the walls of the casing or vat. A closed container having two superimposed com-.
partments occupies the bottom of the casing or vat which rests upon a box or
bed plate inclosing a small hot air motor. It is in the lower compartment of the
above mentioned container that the carbureting is effected. The upper compart-
ment which serves as a reservoir is provided with a tube for the introduction of
the carbureting material, and with a level tube with float, and communicates
with the lower compartment by means of a valve with a float for the automatic
feeding of this latter compartment with the carbureting liquid, and by a tube
for the passage of the carbureted gas from the lower compartment into the upper
compartment where it gets rid of the small quantity of liquid which it has carried
over, in order to pass next, by a tube commanded by a stop cock or valve to the
service pipe.
The air or the gas is brought into the bell by a tube fitted with a valve and is
driven back at a constant pressure into the lower compartment through a tube
fitted with horizontal branches suitably perforated, and arranged in the bottom.
of the said compartment.
The pressure of the gas driven back into the carbureting material being equal
to the weight of the bell, it results that by loading the bell the pressure can be
regulated. In the same manner the height or the thickness of the layer of the
carbureting liquid in the lower compartment can be regulated by raising the ball
of the float of the feed valve upon its lever.
The air or the gas are driven back into the bell by means of a bellows worked
by a rod jointed to the arm of the crank of a hot air motor, heated by means
of the carbureted gas produced in the apparatus, and surmounted by a refrigerat-
ing reservoir. The water in the casing or vat surrounding the two compartments
above mentioned, tends to maintain a constant or even temperature in these latter,
which is in addition assured by the arrangement of the refrigerator immediately
beneath the lower compartment.

We, LEOPOLD LEDERER and JULIUS GOTTLIEB, of. The "Brilliant Luftgas
Works, Eger, Bohemia, Manufacturers, 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:---
Our present invention relates to improvements 'in devices for producing gas for
lighting and other purposes by means of the carburation of air or any other gas,
passed through substances containing a large amount of carbon, such as liquid
hydrocarbon.
The object of the invention is to provide an improved apparatus of this kind,
of simple, and substantial construction, and means for automatically controlling
the pressure of air or gas before passing it through the carburetting substance,
means for automatically controlling the thickness of the layer of carburetting
substance, and means for maintaining the same at an approximately constant
temperature, in order to obtain a uniform and regular carburation and produce
gas, adapted to be advantageously employed for lighting and other purposes.
In the accompanying drawings, is shown a vertical sectional view of one embodi-
ment of the invention.
The improved apparatus is composed of a tank 1 filled with water to three-
fourths of its height. and in which floats an air or gas-holder 2, properly guided
on the walls of the tank, by means of rollers, journaled in brackets, secured upon
the top of said gas-holder. In the lower part of the tank is arranged a reser-
voir, having two sections 3, 4.and.supported by a closed frame 31, containing a
small hot-air motor 21.
The section 3 serves as a reservoir to the section 4 in which the carburation is
produced. The section 3 is provided with a tube-section 11, through which the
carburetting substance is introduced into the apparatus, and with a level-indi-
cator 32. Said section 3 communicates with the section 4, through a valve 33,
provided with a float, as shown in the drawing, to automatically admit carburet-
ting liquid into said section 4, and through a tube 34 for the passage of the car-
buretted gas from section 4 into section 3, where the same is relieved from liquid
it may have carried with it. Thence the gas flows to the burners and the like,
through the pipe 16 provided with a valve 17.
The air or gas enters the holder 2 through a pipe 5, provided with a valve 6,
and is forced at a constant, pressure into. the section or compartment 4, through
a pipe 7, provided with perforated branch pipes 9, arranged at the bottom of said
section, or compartment.
а
The pressure of, the gas forced into the carburetting body or substance, depends
on the weight of the air or gas-holder 2,, so that said, pressure may be easily
regulated by placing weights or their equivalents, upon said air or gas-holder.
The height or thickness of the layer of carburetting liquid may also be regulated
by vertically adjusting the floating ball of the valve 33, on its supporting lever.
The air or gas-holder, is provided with a spring-valve 10, serving to limit the
movement of the holder, by allowing air or gas to leave the latter, when the stem
of said valve engages the top of the tank 1.
The air or gas may be introduced into the holder 2, by means of any preferred
device, but in order to obtain a most simple and economical apparatus, I employ
a hot-air motor 21, heated by means of carburetted gas produced in the apparatus,
said gas being burned in a burner 30, connected to the pipe 16, by means of
another pipe 26. The motor is provided with a refrigerator 25, connected to the

page_text: same, through pipes 23, 24. The fly-wheel of the motor actuates the bellows 20,
through the agency of a connecting-rod 22, said bellows forcing air into the above
holder 2, through the pipe 5.
The water in the tank I and which surrounds the reservoir 3, 4, has a tendency
to maintain the contents. of the latter at a constant temperature, and the arrange-
ment of the refrigerator under the tank 1 adds to this action. When the appa-
ratus is placed in a very cold space, the water in the tank 1 may be somewhat
heated either by means of a burner, or in any other preferred way.
The operation of the apparatus is most simple. To start the motor, a few
revolutions are imparted, by hand, to the fly-wheel thereof, whereby a certain
amount of air will be forced into the carburetting liquid to produce carburetted
gas, which is then burned at 30, care being taken to turn off the valve 17.
The latter is opened only when the motor is completely started. The air, forced
upwards by the bellows 20, enters the air-holder 2, which rises when the pres-
sure becomes higher than the weight of said holder, so that a constant pressure
will be produced within the latter. By the action of such constant pressure, the
air passes into the carburetting liquid to mix with the vapours thereof and produce
combustible gas, adapted to be employed for lighting and other purposes.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is ::-
1. The improved gas-making apparatus, comprising an air or gas-holder,
floating in water and forcing the gas to be carburetted at a constant pressure
into the carburetting reservoir, connected to said air or gas-holder and placed in
water; an automatically operating valve in said reservoir to regulate the admis-
sion of carburetting liquid, and means for forcing the air or gas to be carburetted,
into the said holder, substantially as set forth.
2. The improved gas-making apparatus, comprising a tank containing water,
an air or gas holder floating in said tank, a safety-valve on said air or gas-holder.

reservoir into two sections, a float-valve controlling the admission of carburetting
liquid from the upper section into the lower seetion, in which the carburetting is
produced, a connecting pipe between said sections to lead the carburetted air, or
gas, into the upper section for drying the same, and means for leading and forc-
ing air, or gas, to be carburetted, into the said holder substantially as set forth.
