PROVISIONAL SPECIFICATION.
Improvement in Apparatus for Heating or Cooling Liquids.
I, HUBERT SEILER, Mechanical Engineer, of Gerresheimerstrasse 33, Düssel-
dorf, Germany, do hereby declare the nature of this invention to be as follows:-
This invention has for its object, to construct a heating or cooling apparatus
for liquids which combines efficiency with simplicity of construction, and facility.
of manufacture, and which is specially suitable as a feed water heater.
In the accompanying drawings, Fig. 1 is a vertical section of an apparatus
embodying my invention; Fig. 2 is a vertical section at right angles to Fig. 1,
and Fig. 3 a horizontal section along line A-B of Fig. 1.
The apparatus chiefly comprises an upright hollow body provided with parallel
channels and which receive the liquid to be heated or cooled.
These channels communicate with each other through passages
alternately
at the top and at the bottom, so as to conduct the liquid forward and backward.
The interior of the hollow body serves as heating chamber.
In the example represented by the drawings, two compartments c and d have been
provided, which are surrounded by additional compartments e, f, g and h, adapted
to conduct the heating or cooling medium, for instance steam, one after the other
or simultaneously. In the example shown, the water enters through the inlet
pipe s, then flows through the canals a and passes through the short canal
into the channels b. After having passed through all of these, it leaves the
apparatus through the short pipe m. The steam enters the chambers c and d
through the inlet pipe n, then passes at o into the chamber c, thence through
the canals to the compartments f and y, and finally through the canal to
the outlet . The uncondensed steam, together with the air contained in the
same, escapes through the pipe r.
Owing to the length of the way which the liquid to be heated or cooled must
take in passing through the canals a and b, on which way it is constantly exposed
to the influence of the steam or other heating or cooling medium, the heating
or cooling efficiency of the apparatus is very high. The number of external
heating or cooling compartments may be reduced or increased, the apparatus
may have a rectangular or other suitable cross section, and is provided at the
bottom with discharge openings or draw-off devices for the water of condensation.
Instead of having an upright position, as shown by the drawing, the apparatus
may be arranged horizontally or in any other convenient position.

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention has for its object, to construct a heating or cooling apparatus
for liquids, which combines efficiency with simplicity of construction, and facility
of manufacture, and which is specially suitable as a feed water heater.
In the drawings filed with the Provisional Specification, Fig. 1 is a vertical
section of an apparatus embodying my invention; Fig. 2 is a vertical section at
right angles to Fig. 1, and Fig. 3 a horizontal section along line A-B of Fig. 1.
The apparatus chiefly comprises an upright hollow body provided with parallel
channels a and b which receive the liquid to be heated or cooled.
These channels communicate with one another through passages
alternately
at the top and at the bottom, so as to conduct the liquid forward and backward.
The interior of the hollow body serves as heating chamber.
In the example represented by the drawings, two compartments c and d have been
provided, which are surrounded by additional compartments e, f, g and h, adapted
to conduct the heating or cooling medium, for instance steam, one after the other
or simultaneously. In the example shown, the water enters through the inlet
pipes, then flows through the canals a and passes through the short pipe l
into the canals b. After having passed through all of these, it leaves the
apparatus through the short pipe m to the exterior. The steam enters the
chambers c and a through the inlet pipe n, then passes at o into the chamber e,
thence through the canals to the compartments f and y, and finally through
the canal to the outlet r The uncondensed steam, together with the air con-
tained in the steam, escapes through the pipe r.
Owing to the length of the way which the liquid to be heated or cooled must
take in passing through the canals a and b, on which way it is constantly exposed
to the influence of the steam or other heating or cooling medium, the heating
or cooling efficiency of the apparatus is very high. The number of external
heating or cooling compartments may be reduced or increased, the apparatus
may have a rectangular or other suitable cross section, and is provided at the
bottom with discharge openings or draw-off devices for the water of condensation.
Instead of having an upright position, as shown by the drawing, the apparatus
may be arranged horizontally or in any other convenient position.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. Apparatus for heating or cooling liquids, chiefly consisting of a hollow
body which contains canals a and b communicating with one another at the ends
and conducting the liquid to be heated or cooled; while inside and outside the
said canals are arranged compartments which conduct the heating or cooling
medium, substantially as described.
2. Apparatus for heating or cooling liquids, constructed and adapted to operate
as described and shown by the drawings.
