PROVISIONAL SPECIFICATION.
An Improved Distilling Apparatus.
I, ALPHONSE LAVY, of 95 Boulevard Beaumarchais, Paris, in the Republic of
France, do hereby declare the nature of this invention to be as follows:-
My invention relates to an Improved Distilling Apparatus.
Above the
My apparatus comprises a boiler heated by any suitable furnace.
boiler, and firmly connected thereto, I provide a dome which contains a number of
baffle plates forming chambers which I vary according to the degree of alcohol to
be obtained.
I provide a pipe for the admission of the liquid to be treated which pipe is
provided with any suitable cock by means of which the said pipe can be put into
communication with the cask, tun, or the like containing the said liquid. From
this pipe the liquid to be treated-for instance, wine-enters a double coiled pipe
and circulates in the outer tube of the coil and flows through a small tube into the
first chamber, through a pipe passing to the second chamber and so on, from
chamber to chamber until it arrives in the lowermost chamber. The said lowermost
chamber is pierced with small holes to allow the wine to penetrate into the boiler
below the dome. The alcohol vapours rise through a central tube extending
through all the chambers and are carried to the small central tube of the coil
where they are condensed and the alcohol is conducted through the tube to the
bottom of the dome outside thereof, and there collected. The bottom of each
chamber is undulated; this arrangement having the advantage of increasing the
contact surfaces of the wine and alcohol vapours, which, in rising, spread, in
proportion as they ascend, into the chamber; 1 further provide partitions in the
interior of each chamber.
It will be seen that in my improved distilling apparatus above described, the
alcohol, from the boiler to the point where it is collected at the end of the tube at
the bottom of the dome, is always surrounded by the wine which is to be
subsequently converted into alcohol, therefore there is a rational flow of wine and
alcohol, as the latter in condensing gives up its heat to the wine which is admitted
into the boiler at a relatively high temperature.
My apparatus for the continuous distillation without the use of water, gives
rectified brandies at one operation, but it is clear that the principle on which the
construction of the dome is based, riz. :-the employment of an alcohol chamber
between two refrigerating liquid chambers, is applicable to distilling apparatus in
which water is used as the refrigerating liquid. In this case, the wine to be
distilled is passed directly into the boiler, and the water follows the same path as
that followed by the wine as the above mentioned; but instead of entering the
boiler, it is carried away through a tube opening into the last chamber which, in
this case,
is not in communication with the boiler.

page_text: An Improved Distilling Apparatus.
I, ALPHONSE LAVY, of 95 Boulevard Beaumarchais, Paris, in the Republic of
France, 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 an Improved Distilling Apparatus which I will proceed
to describe in detail with reference to the annexed drawings in which
Figure 1 is a side elevation, and
Figure 2 a vertical central section of my improved apparatus.
My apparatus comprises a boiler A heated by any suitable furnace provided
with a door B. Above the boiler and firmly connected thereto I provide a dome B¹
which contains a number of plates or diaphragms forming chambers, which vary in
number according to the degree of alcohol to be obtained.
I provide a pipe 2 for the admission of the liquid to be treated, which pipe is
provided with a suitable cock, not shown in the drawings, by means of which the
said pipe can be put into communication with the cask, tun or the like containing
the said liquid. From this pipe 2, the liquid to be treated-for instance, wine-
enters a double coiled pipe C, circulates in the outer tube of the coil and flows
through a small tube 3 into the first chamber 4, whence it passes to the second
chamber 5 through a pipe 4', and so on, from chamber to chamber until it arrives
in the lowermost chamber 15. The said lowermost chamber is pierced with small
holes 16 to allow the wine to penetrate inte the boiler below the dome. The
alcohol vapours rise through a central tube 17 preferably formed in sections as
shown and extending through the liquid chambers above described; the said tube
serves as a communication between intermediate vapour or alcohol chambers a, b, c,
d, e, f, g, h, i, j and k wherein a portion of the heat in the said vapours is transmitted
through the separating plates to the liquid in the intermediate chambers 4 to 15;
the vapours are thence carried to the small central tube 18 of the coil C, where
they are condensed, and the alcohol is conducted through the tube 19 at the bottom
of the dome and there collected. The bottom of each chamber is undulated; this
arrangement having the advantage of increasing the contact surfaces of the wine
and the alcohol vapours, which, in rising, spread, in proportion as they ascend into
the chambers.
In some cases, moreover, I find it advantageous to provide baffle-plates or
partitions in the interior of the said chambers to control the flow of liquid or
vapour therein.
It will be seen that, in my improved distilling apparatus above described, the
alcohol, from the boiler to the point where it is collected at the end of the tube 19,
at the bottom of the dome, is always surrounded by the wine which is to be
subsequently converted into alcohol, therefore there is a rational flow of wine and
alcohol, as the latter, in condensing, gives up its heat to the wine, which is admitted
into the boiler at a relatively high temperature.
My apparatus for continuous distillation without the use of water, gives rectified
brandies at one operation, but it is clear that the principle on which the construction
of the dome is based, viz. :-the employment of an alcohol chamber between two
refrigerating liquid chambers, is applicable to distilling apparatus in which water
is used as the refrigerating liquid. In this case, the wine to be distilled is passed
directly into the boiler, and the water follows the same path as that followed by
the wine as above mentioned; but, instead of entering the boiler, it is carried away
through a tube opening into the last chamber 15 which, in this case, is not in
communication with the boiler.

page_text: 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 :-
First. A rectifying apparatus divided into a number of chambers arranged
alternately for the cooling liquid and the alcoholic vapours, the communication
between the chambers being established in such a manner that a chamber for
receiving the alcoholic vapours is always between two chambers for receiving the
cooling liquid, substantially as set forth.
Second. The combination, with a rectifier, of a worm or helically wound tube,
an interior tube in the said worm, and means for conducting alcoholic vapours into
the said worm, substantially as set forth.
Third. The combination, with a rectifier, divided into a series of compartments,
the alternate compartments of which are in communication with each other, of a
worm in communication with one set of compartments and a tube in the said worm
in communication with the other set of compartments, substantially as set forth.
