Improvements in Ships for the Transport of Fruit, Meat, and other
Perishable Freight.
I, JOHN MCINTYRE, Engineer, of 46, Ogden Avenue, Jersey City Heights, in
the County of Hudson, and State of New Jersey, United States of America, do
hereby declare the nature of this invention to be as follows:-
My invention relates to a ship for the transport of fruit, meat, and other
perishable freight, and it has for its principal object to keep the storage compart-
iment properly ventilated and at a uniform low temperature.
The invention consists principally of a storage compartment having a false bottom
to form an air distributing chamber under the said storage compartment and air
spreading chambers arranged at opposite ends of the said storage compartment and of
which one is connected with the said distributing chamber and the other with the
upper part of the storage compartment.
The storage compartment in which the fruit, meat, or other perishable freight, is
to be placed is provided with a perforated bottom below which is formed an air
distributing chamber provided at the front end with an air inlet opening extending
the entire width and serving to connect the air distributing chamber with an air
spreading chamber, the opening being provided with a valve for increasing or
diminishing the opening to admit more or less air to the air distributing chamber
from the said spreading chamber. The air spreading chamber is built on the
front end of the storage compartment and is connected with the discharge end
of a blower located in a blower chamber arranged next to the spreading chamber,
the mouth of which blower extends across the entire width of the chamber to
spread the air uniformly therein. In the chamber is arranged a refrigerating
coil through which a cooled fluid is forced by means of pumps or other mechanism
so that the air discharged by the blower and passing over the said coil is reduced
in temperature before it passes into the distributing chamber. The blower chamber
is connected by a passage-way with a second spreading chamber arranged on the
end of the storage chamber opposite that on which the first mentioned spreading
chamber is located. This second chamber is preferably arranged at the top and
connects by an outlet opening with the storage compartment so that the air from
the latter can pass into said chamber and from the latter return through the passage
into the blower chamber to be again taken up by the blower and forced into
the first spreading chamber and through the opening into the air distributing
chamber and thence through the perforations in the bottom of the storage com-
partment. The outlet opening which connects the second spreading chamber with
the storage compartment, is provided with a valve for increasing and diminishing
the said opening to regulate the outflow of the air from the compartment.
In case the refrigerating coil is not used and it is only desired to circulate
fresh air through the storage compartment, the blower chamber is opened to the
outer air by removing a cap on the top of the chamber. A like cap being
removed from the second spreading chamber so that air drawn into the blower
chamber from the outside by the blower is forced through the first spreading
chamber, the distributing chamber and the storage chamber and its contents, to
finally pass through the opening in the second spreading chamber and out of the
same through the opening previously closed by the cap. The air inlet and outlet
openings extend throughout the width of the spreading distributing and storage
chambers respectively so that the air passes from the spreading chamber in sheet
form to the distributing chamber from which it rises uniformly through the
perforated bottom into all parts of the storage compartment. The air is drawn

page_text: from the latter in sheet form through the outlet opening into the second spreading
chamber to be either returned to the blower as above described or permitted to
escape to the outer air in case the cap is removed as above described.
It will be understood that the perforated false bottom and the inlet openings
extending across the entire width of the chambers, are very essential features to
insure a uniform distribution and movement of air in the storage compartment, so
that all the air is kept in constant motion and no foul air pockets are formed in any
part of the said storage compartment. It is also understood that the air would not
spread through the entire length, width, and height, of the storage compartment if
the floor of the latter had only an ordinary hatch opening of sufficient area to allow
the entering reduced volume of air to pass through it as the air would then seek a
direct route to the outlet opening and only a small part of the compartment would
be ventilated and cooled and foul air pockets would be formed.
The movement of the air may be reversed by connecting the mouth of the blower
with the channel leading to the second spreading chamber and uniting the first
spreading chamber and the blower chamber. The air in this case would be forced
by the blower through the channel to the second spreading chamber into the storage
compartment and descend in the same to the distributing chamber, to finally pass
into the first spreading chamber and blower chamber and back to the blower to be
used over again.

COMPLETE SPECIFICATION.
Improvements in Ships for the Transport of Fruit, Meat, and other
Perishable Freight.
JOHN MCINTyre, Engineer, of 46 Ogden Avenue, Jersey City Heights,
in the County of Hudson & State of New Jersey, United States of America,
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 a ship for the transport of fruit, meat, and other perishable
freight, and it has for its principal object to keep the storage compartment properly
ventilated and at a uniform low temperature.
The invention consists principally of a storage compartment having a false bottom
to form an air distributing chamber under the said storage compartment, and
air spreading chambers arranged at opposite ends of the said storage compartment,
and of which one is connected with the said distributing chamber and the other
with the upper part of the storage compartment.
The invention also consists of certain parts and details and combinations of the
same, as will be fully described hereinafter and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 is a part longitudinal section of a vessel provided with the improvements
of this invention. Figure 2 is a transverse section of the same on the line 2-2 of
Figure 1 and Figure 3 is a like view of the same on the line 3-3 of Figure 1.
The vessel A, is provided with a storage compartment B, in which the fruit,
meat, or other perishable freight is placed in any suitable manner, which
compartment B is furnished with a perforated bottom C, below which is formed .an
air distributing chamber D, having at its front end an air inlet opening E, extending
the entire width of said end, as plainly shown in Figure 3. The inlet opening E
connects the air distributing chamber D with an air spreading chamber F,.and is

page_text: provided with a valve G, for increasing or diminishing the opening to admit more
or less air to the air distributing chamber D from the said spreading chamber F.
This spreading chamber F is arranged at the front end of the compartment B, as
plainly shown in Figure 1, and is connected with the discharge end of a blower G',
of any approved construction located in a blower chamber H, next to the spreading
chamber F, the mouth of which blower extends across the entire width of the
chamber F so as to spread the air uniformly therein. A refrigerating coil I is
arranged in chamber F, through which a cooled fluid is forced by means of pumps
or other mechanism, so that the air discharged by the blower G and passing over
the said coil I is reduced in temperature before it passes into the distributing
chamber D.
The blower chamber H is connected by a passage way J, with a second spreading
chamber K, arranged on the end of the storage chamber B opposite that on which
the spreading chamber is located. This chamber K is preferably arranged at the
top and connects by an outlet opening L, with the compartment B, so that the air
from the latter can pass into the chamber K and from the latter return through the
passage J into the blower chamber H, to be again taken up by the blower and
forced into the first spreading chamber F and through the opening E into the air
distributing chamber D and thence through the perforations in the bottom C of the
compartment B. The outlet opening L of chamber K is provided with a valve N,
for increasing or diminishing the said opening to regulate the outflow of the air
from the compartment B.
If it is only desired to circulate fresh air through the storage compartment B,
and the refrigerating coil is not used, the blower chamber H is in this case opened
to the outer air by removing a cap H', on the top of the chamber, as shown in
Figure 1, a like cap K' being removed from the spreading chamber K, so that air
drawn into the blower chamber H from the outside by the blower G¹, is forced
through the spreading chamber F, the distributing chamber D and the storage
chamber B, and its contents, to finally pass through the opening L in the second
spreading chamber K, and out of the same through the opening previously closed
by the cap K.
As shown in Figure 3, the valve G can be raised or lowered by suitable
mechanism, but I do not limit myself to the especial mechanism shown.
The openings E and L extend throughout the width of the chambers F, D and B,
respectively, so that the air passes from the spreading chamber F in sheet form to
the distributing chamber D, from which it rises uniformly through the perforated
bottom C into all parts of the storage compartment B. The air is also drawn from
the storage compartment in sheet form through the outlet opening L into the second
spreading chamber, to be either returned to the blower as above described or
permitted to escape to the outer air in case the cap K¹ is removed as above described.
It will be understood that the perforated false bottom and the inlet openings
extending across the entire width of the chambers, are very essential features to
insure a uniform distribution and movement of air in the storage compartment B,
so that all the air is kept in constant motion and no foul air pockets are formed in
any part of the said storage compartment.
It is also understood that the air would not spread through the entire length,
width and height of the storage compartment B, if the floor of the latter had only
an ordinary hatch opening of sufficient area to allow the entering reduced volumes
of air to pass through it, as the air would then seek a direct route to the outlet
opening, and only a small part of the compartment B would be ventilated and
cooled, and foul air pockets would be formed.
The movement of the air may be reversed by connecting the mouth of the
blower G¹ with the channel J, and uniting the chambers F and H. The air in this
case would be forced by the blower through channel J and spreading chamber K
into the storage compartment B, and descend in the same to the distributing
chamber D to finally pass into the chambers F, H, and back to the blower to be
used over again,
