page_text: I, CONRAD HERZOG, of Mansion House Chambers, Queen Victoria Street, in the
city of London, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
:-
My invention relates to apparatus for carburetting air for lighting and heating
purposes, or for enriching gas poor in carbon.
The object of my said invention is to provide carburetting apparatus which is of
simpler construction and cheaper than that heretofore used, and to this end it comprises
improvements as hereinafter described.
-
According to my said invention I provide a chamber or vessel of cylindrical or
other shape having placed therein a number of superposed trays or dishes adapted to
contain gasoline or other hydrocarbon of a volatile nature, and hereinafter termed the
carburetting chamber.
The upper tray is connected with a suitable reservoir, or with a filling opening, for
the hydrocarbon, by means of a syphon or other tube; and the hydrocarbon as it
escapes or overflows from the upper tray falls into those below it.
The said trays are alternately provided with openings at their centre and near their
edges, so that when air or gas caused to pass through the apparatus as hereinafter
described it will travel in a circuitous direction and thus be brought into contact with
a large surface of hydrocarbon. The surplus of hydrocarbon flowing from the upper
tray passes into the lower trays through the said openings, and thence into the bottom
of the apparatus from whence it can be drawn off or otherwise removed from time to
time for reuse.
The means for causing the passage of air or gas through the chamber comprise a
collapsible or telescoping casing, the interior of which is normally in communication
with the carburetting chamber. This casing when expanded or elongated is adapted
to be filled with air or gas from any suitable source, and then as the said casing
collapses or becomes shorter owing to its weight or an auxiliary weight, the air or gas

page_text: therein is forced through the said carburretting chamber. The said casing is advan-
tageously provided with a counterweight or counterweights so as to facilitate its
expansion or elongation one or more of the said weights being removed to allow the
casing to collapse.
The carburetted air or gas escapes through an opening below the trays.
A cock is provided in the connection between the carburetting chamber and the
interior of the collapsible casing, by means of which the interior of the said casing
may be placed in communication with the atmosphere or a supply of gas to be
carburetted or enriched, and cut off from the carburetting chamber.
In large apparatus I can arrange two collapsible or telescoping casings in connection
with one carburetting chamber, so that the supply of air or gas can be continuously
maintained. I can also employ a gas-holder into which the carburetted air or gas
may be delivered prior to consumption.

Improvements in Apparatus for Carburetting Air and Enriching
Gas.
I, CONRAD HERZOG, of Mansion House Chambers, Queen Victoria Street, in the
City of London, Civil 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 apparatus for carburetting air for lighting and heating
purposes, or for enriching gas poor in carbon.
The object of my said invention is to provide carburetting apparatus which is of
simpler construction and cheaper than that heretofore used, and to this end it comprises
improvements as hereinafter described.
In the accompanying drawing
Figure 1 is an elevation of my improved apparatus partly in section, and
Figure 2 is a plan of the same.
Figure 3 is a vertical section of the carburetting chamber hereinafter described, and
Figure 4 is a plan of the same."`
Figure 5 is a sectional view of a cock used in the apparatus, and
Figure 6 is a view of a modified form of cock.
a is a chamber or vessel of cylindrical shape having placed therein a number of
superposed trays or dishes 6 adapted to contain gasoline or other hydrocarbon of a
volatile nature and hereinafter termed the carburetting chainber. These trays are
supported within the cylinder a upon two semicircular pieces c, c which are held in
their proper relative positions by the rod d having right and left banded screw threads
on its opposite ends so that the pieces can be readily fixed in place. The said trays
are provided with openings e, e at opposite sides of the same so that when air or gas
is caused to pass through the apparatus as hereinafter described it will travel in a
circuitous direction and thus be brought into contact with a large surface of hydro-.
carbon.
The upper tray is provided with a filling opening for is connected with a suitable
reservoir for the hydrocarbon by means of a syphon or other tube, the said reservoir
being preferably located outside the building in which the apparatus is fixed.
The hydrocarbon as it escapes or overflows from the upper tray falls into those
below it. The surplus of hydrocarbon flowing from the upper tray passes into the
lower trays through the openings e, e. and thence into the bottom of the apparatus
from whence it can be drawn off through a cock g or otherwise removed from time to,
time for reuse.
The means for causing the passage of air or gas through the chamber a comprise
two collapsible or telescoping casings or chambers h, h¹ which are secured at their
lower ends to the circular bases i, i and at their upper ends to the discs i¹,,
interiors of the said casings being adapted to be placed in communication with the
the

page_text: carburetting chamber through a three-way cock j, Figure 5. These chambers h, h¹ are
preferably constructed of flexible airtight material such as waterproofed cloth. Each
of these casings when expanded or elongated is adapted to be filled with air or gas
from any suitable source and then as the said casing collapses or becomes shorter
owing to its weight or to an auxiliary weight or weights k the air or gas therein is
forced through the pipe or into the said carburetting chamber and from the latter
the carburetted air is forced through the pipe m to the points where it is required
for use.
n, n are counterweights which are connected by chains n', n' to the tops of the
expansible chambers so as to facilitate their expansion or elongation.
The object of employing two collapsible chambers is to allow the filling of one
chamber while the other is being emptied.
o, o are valves one of which is arranged in the base of each collapsible or expansible
chamber and which are adapted to allow the admission of air into the latter when
extended. Each valve is connected by a chain to the top of the said chamber so as to
be positively, lifted when the chamber has been extended to a given point. These
valves are of such size as to allow the air holders to be filled almost instantaneously.
The operation of my apparatus is as follows, that is to say :-Assume the trays b, b
in the chamber a to have been filled. with gasoline or the like, and the chamber ¹ to
be extended by pulling the chain n' by hand. During the greater part of the
expansion of the said chamber the air raises the valve o but when the chamber has
been almost completely extended if further extension of the same does not create
sufficient vacuum within the chamber to lift the valve, at this point the valve is lifted
by the chain attached thereto so that the chamber is completely filled with air. When
the hand is removed from the chain n' the weight k causes the top of the chamber to
descend slightly as shown in dotted lines so that the valve also closes as shown in
dotted lines and the air is placed under pressure. If now the plug of the cock j is
turned to the position shown in Figure 5 the air will be forced through the pipe into
the carburetting chamber a and thence after having been carburetted through the
delivery pipe m.
Before the chamber h¹ is quite empty the chamber h is filled with air as hereinbefore
described so that when the chamber his empty the air in the chamber h can be forced
into the carburetting chamber by simply turning the plug of the cock j. The
chamber is then in its turn again filled, and so on, whereby a continuous current of
air is supplied without interrupting the light.
I do not limit myself to the construction hereinbefore described as it is obvious that
it may be considerably modified, for instance the valves o can be dispensed with. In
this case however it is necessary to provide a four-way cock as shown in Figure 6, so
that while one collapsible chamber is under pressure the other is drawing in air
through the opening p in the said cock. To extend each chamber / or /¹ it is
advantageous to place an auxiliary weight upon the weight a sufficient to overcome
the normal weight of the chamber.
When my apparatus is to be used for supplying a small number of lights, one of the
extensible chambers can be dispensed with the single chamber being of sufficient size
to supply such a quantity of gas that it will not be necessary to refill the chamber
with poor gas or air while the lights are burning. Also when very large quantities of
gas are required I may employ three or more extensible chambers in conjunction with
one carburetting chamber or one large gas holder of ordinary construction.
It is obvious that if the extensible chambers are filled with gas poor in carbon that
such gas will be enriched by passing it through the carburetting chamber.
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 carburetting or enriching air or gas, comprising a carburetting
chamber containing a number of superposed trays having openings arranged therein
in such a manner that air forced through the said chamber is caused to pass in a

page_text: circuitous direction whereby it is brought into contact with a large surface of liquid,
in combination with a collapsible chamber adapted to be filled with air or.gas and
then to be lowered under the action of a weight or the like to force the air or gas
which it contains through the carburetting chamber, or two or more of such chambers
to maintain a continuous current of air or gas.
2. In apparatus for carburetting air or enriching gas, a carburetting chamber
containing a series of superposed trays constructed and arranged substantially as
described.
3. In air carburetting or gas enriching apparatus the use of one or more flexible or
other extensible and collapsible chambers for containing the air or gas to be carburetted
or enriched, substantially as described.
4. The improved apparatus constructed and arranged substantially as described with
reference to the accompanying drawing.
