Improvements in Apparatus applicable for Evaporating Liquids or
Saccharine Solutions.
We, JAMES AUGUSTINE MORRELL of 610 Magazine Street, New Orleans in
the County of Orleans and State of Louisiana, United States of America, Physician,
and JOSEPH FROMHERZ of 304 South Franklin Street, New Orleans aforesaid,
Builder, 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 invention relates to an improvement in apparatus for evaporating liquids or
saccharine solutions, and its novelty will be fully understood from the following
description and claim, when taken in connection with the annexed drawings.
The objects of our iuvention are to evaporate liquids in transit by means of
nitrogenous vapour, surcharged or impregnated with electricity, which will be blown
in contact with and through the liquid. We attain these objects by the mechanism
illustrated in the accompanying drawings, in which :-
Figure 1 is a vertical sectional view of our improved apparatus ;
Figure 2 is a top view of one of the plates;
Figure 3 is a sectional side view of evaporating apparatus ;
Figure 4 is a side view of air-pipe; and
Figure 5 is a top view of tube, showing core in same;
Similar letters refer to similar parts throughout the several views.
To carry our invention into effect, we use an apparatus such as shown in
Figure 1. Referring by letter to the various parts, A, designates a metal shell, in
which are placed plates B, which hold pipes C in position. These pipes are
preferably constructed of copper and may be of any desired length, say thirty or
forty feet.
Within these pipes we place cores, as shown by D, which are held in centre of
pipes C by suitable means, and the core causes the liquid to assume an annular
form, thus placing the liquid or saccharine solution near the outer periphery of the
pipe, whereby the conversion of the water in the saccharine solution into steam is
facilitated. E is a liquid chamber, F designating an air chamber; G an inlet pipe
for liquids; H an inlet pipe for air, and in which is placed a wire for conveying an
electric current within air chamber F. Extending upward from air chamber F are
pipes Q, said pipes having a spiral end, as shown in Figure 4, and when in position
extend upward in lower end of pipes C, so as to enable a discharge of air to be
made in a twisting or curling current and rendering more effective service.
K shows a waste pipe provided with a cock. L are braces or posts suitably placed
on a bed plate or foundation and which support our evaporator. M is an inlet for
steam into shell A. N is a pipe connecting shell A and worm column R, and
through which steam passes from A to R and heats liquid while in transit through
worm S, and at a point shown by T is an outlet for steam. O is a goose neck through
which liquid and vapour passes from evaporator shell A to column R, and as the
liquid passes from A through the goose neck it strikes the deflector and the top of
the worm and causes a separation, the vapour going in one direction and the liquor
descending through worm. P is a metal cover provided with stuffing-boxes, which
can be packed with asbestos, whereby the iron funnel mouth cover W is free to
move in said boxes and thus allow the pipes C to expand when heated. U is a
reservoir for condensed vapour, which is provided with a discharge cock, as
illustrated, and V is an outlet for condensed vapour in column.
In operation, the liquid or saccharine solution is fed into the chamber E through
pipe G, and it ascends into the pipes C being subjected while flowing into said

page_text: pipes to a blast of heated nitrogenous vapour which is surcharged or impregnated
with electricity, whereby its efficiency as a crystallising agent of the solution is
increased. To deoxidise the air or convert the same into nitrogenous vapour, we
force it through scrap copper placed in a cast iron chamber, which is heated to a
red heat. The air in its transit from the heating chamber to the air chamber F of
the apparatus is carried through an iron pipe, which contains a continuous copper
coil, through which electricity is generated, whereby it will be perceived that by
reason of the friction of the vapour in passing along the copper coil it will become
charged therefrom. The charged vapour is forced by suitable means upward
through pipes Q and into the liquid or saccharine solution in pipes C, the latter
pipes being heated by steam to any desired temperature, preferably from 900 to
1000 degrees Fahrenheit, and through the employment of the cores D, the con-
version of the water in the solution into steam is accelerated, and the steam passes
from the shell A to evaporator, as heretofore described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is-
The improved apparatus for evaporating liquids, consisting of a shell having
steam inlet and outlet ports, pipes arranged in said shell and connected by plates;
core rods placed in said pipes, a liquid chamber arranged beneath and communicating
with the pipes, a liquid feed pipe leading into said chamber, an air chamber
arranged beneath the liquid chamber and having an inlet port, and pipes leading
up from the air chamber through the liquid chamber and to connect the air chamber
and the pipes, substantially as and for the purpose set forth.
