that I, the said Edward Heinson Huch, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Edward Heinson Iuch, do hereby
declaro the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say: -
This Invention has for its object an adaptation of the cooling machine
described in the Specification of a Patent granted to Franz Windhausen,
of the City of Brunswick, Germany, Civil Engineer, for an Invention
for "Improvements applicable to Freezing and Ice-making Machines,"
and dated the 5th day of March 1869, No. 669.
This improved machine is according to this Invention adapted in the
following manner to the storing and preserving of meat and other
articles of food whilst being conveyed from place to place on board
ship-For this purpose Windhausen's air cooling machine is erected on
board the ship, and so arranged that it may be driven from the ship's
engines. Loading or storing rooms for the meat or other articles of food
are also constructed on board the ship; they are made with double walls
or sides, which should be air-tight, and the spaces between the double
sides may be filled with non-conducting material or left vacant. Pipes
are led from the air-cooling apparatus into the loading or storing rooms
to convey into the rooms the cold air from the cooling machine, and also
to draw out of the rooms the air which has become partially warmed by
absorbsion of heat from the contents of the rooms. In this way the
meat or other articles of food may be kept at so low a temperature as to
remain unchanged during a voyage of any length.
The annexed Drawing shows a longitudinal and cross section of a
vessel fitted with apparatus such as is above described.

page_text: A represents that part of the ship which is used as the storing room
in which the fresh meat, etc. is kept. This room can either be divided
by partitions and d in two or more parts; or it may be used as one
single room in its whole size. This room, as the Drawing shows, has
double walls, and between them is put some non-conducting material,
felt or other material, which is surrounded on one or on both sides by
isolated air. By means of the double trap doors a the meat, eto. can bo
put into the storing room. The storing room, as shewn in the Draw-
ing, is divided by a partition wall with door in it into two parts, and
contains besides a moveable partition on rollers c. In the storing room
are the trap doors L and L', which can be opened by loops if necessary.
The storing room is further provided with iron bars e, which go through
and across it, and on which hangs the meat, etc. The valves v, V,
facilitate the circulation of the cold air from one part of the storing
room to the other if necessary. Particular attention is to be given to the
deck of the ship forming the upper part of the storing room, so as to
prevent the effect of the sun by means of careful insulation.
In the storing room the meat will be preserved quite fresh by means
of cold air produced by the cold air apparatus, so that the meat contains
and retains even after a long voyage all its original nutritious matter.
The cold air apparatus can consist, according to circumstances and
according to the dimensions of the storing room, either in a single or a
double machine, and the apparatus may be worked in different ways.
1. Either the ship's engines M are connected by means of a shaft with
the cold air apparatus K so that the latter is worked by the ship's
engines.
2. Or a steam engine I, I, I, is connected by means of a coupling rod
with the cold air apparatus, and is worked from the boiler of the ship's
engines.
3. Or the cold air apparatus is worked by means of a separate steam
engine, totally independent from the ship's engines.
K represents the cold air apparatus; S, the fly wheel of the same;
I and I, I, the two cylinders, which, according as it may be required, can
be used both at the same time or singly; shows the condenser of the
cold air apparatus. The cold air produced goes from the cold air
apparatus through the pipes and in the direction of pand into the
storing room. In case only one of the cylinders is used, say cylinder 1.,

page_text: the cold air produced can be led back again from the storing room
through the curved pipe II to the cold air apparatus, so that the already
oooled air goes a second time through the cold air apparatus; " shows
the way of the cold air back again to the cold air machine. Just the
same applies to cylinder I, I, for the cold air by means of the curved
pipe II in directions p". Through the valves the cold air can stream
into one or both parts of the storing room. The pipes I and II' are
moveable for the purpose of effecting the cooling of one part of room A
separately. In that case the connection of H' with 2 is broken as well
as between II and r; valve v is then to be shut, and that part of pipe r
which goes through the other compartment is to be shut by valve v¹.
The cold air then streams from cylinder I in direction p through
piper, and escapes through the open valves L' into the first part of
storing room A, and is then led back again through the open pipe II in
direction of 2" to the cold air apparatus for further cooling; the same
applies to the second part of room A and cylinder I, I.
If both the cylinders are used at the same time the cold air is
conveyed from each cylinder through the corresponding pipes to the
Corresponding compartment of the storing room, and when the ship is
loaded this cold air is led back again through the curved pipes to the
cold air apparatus for further cooling, and to be used a second time.
Experiments with this cold air apparatus have proved that the cold
air streams out of the pipes with a temperature of 40° Centigrade. In a
well insulated storing room, with very little expense and with a small
amount of continuous labour, such a low temperature can be maintained
as is necessary for the complete and effective preserving of meat, etc. in
its natural condition with all its original nutritious matter.
When these transport vessels are loading it is necessary first to pump
tho atmosphereio air out of the rooms intended for receiving the
meat, etc., so as to keep up a current of fresh air through the rooms
whilst they are being filled; this is done with the cold air apparatus.
After the vessel is loaded and the storing room closed the temperature
is brought to such a low degree as is necessary for the preserving of the
meat, etc., and this temperature can be kept up for any length of time;
thus the problem of preserving meat, etc. in its natural state, with all its
original nutritious qualities for any length of time has been solved most
satisfactorily and completely.

page_text: Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that what
I claim is, the method and apparatus for storing and preserving moat
and other articles of food on board ship, as herein described.
In witness whereof, I, the said Edward Heinson Huch, have a
hereunto set my hand and seal, this Twenty-first day of Septem-
ber, in the year of our Lord One thousand eight hundred and
sixty-nino.
Brunswick, the 21th of September, 1869.
