Office," Southampton Buildings, London, Doctor of Laws, for the
Invention of "IMPROVEMENTS IN REFRIGERATING APPARATUS." -A com-
munication from abroad by John Jones Bate, of Brooklyn, New
York United States of Amarion Merchant
Scaled the 9th February 1875, and dated the 15th December 1874.
COMPLETE SPECIFICATION filed by the said George Haseltine at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 15th December 1874, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," Southampton Build-
ings, London, Doctor of Laws, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
REFRIGERATING APPARATUS," and have petitioned Her Majesty to grant
unto me, my executors, administrators, and assigns, Her Royal Letters
Patent for the same, and have made solemn Declaration that it has

page_text: been communicated to me from abroad by John Jones Bate, of Brooklyn,
New York, United States of America, Merchant.
NOW KNOW YE, that I, the said George Haseltine, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement, reference being had to the accompanying Drawing forming a
part of this Specification :-
This Invention relates to that class of refrigerators designed for pre-
serving meat, fruits, vegetables, and the like, and in which the air confined 1
within a closed refrigerating room is caused by mechanical means to
pass repeatedly through an ice box to insure the desired reduction of its
temperature, and the elimination from it of undue moisture.
The said Invention comprises a double-throated ice box arranged
within a room or chamber closed against access of external air, and so 1
combined with a fan or other air-driving mechanism that the air confined
within the aforesaid chamber will be drawn from all directions to the ice
box, and diffused in all directions therefrom without the use of dis:
tributing pipes.
The said Invention also comprises the construction of the aforesaid a
ice box with its inlet and outlet throats or openings, one or both, of
smaller diameter than the box itself, in order that the air may be caused
to pass through the mass of broken ice instead of between the said mass
and the sides of the box.
The said Invention further comprises the arrangement of the double- ;
throated ice box constructed as described, and provided with a fan
blower or equivalent in a corner of the room or chamber closed against
access of external air, and in such relation to the walls thereof that the
said walls shall deflect the air to and from the throats of the icc box as
it passes through the latter in such manner as to insure an equable and
diffused circulation of the air within the chamber.
The said Invention further comprises a novel combination of a flaring
hood, or flaring hoods, with the double-throated ice box provided with a
fan blower or its equivalent, whereby the air deflected by the walls of
the closed room is caused to pass from or to and from the ice box in
such directions as to strike the walls at angles most conducive to their
deflecting agency upon the circulating air.

page_text: The said Invention further comprises certain other novel combinations
of parts, whereby the more efficient operation of the herein-before.
named features is secured.
The said Invention is more especially advantageous with or for refri-
gerating rooms of comparatively small capacity and affording but little
space for the pipes, which in larger rooms are found of decided practical
advantage.
Figure 1 is a vertical transverse section of a refrigerator constructed
according to the said Invention; Figure 2 is a horizontal section of the
same on the line y, y, Figure 1.
Figure 3 is a vertical transverse section of a modification of the same;
and Figure 4 is a similar view of another and important modification of
the said Invention.
A is the refrigerating room or chamber of rectangular form and closed
when in use against access of external air. B is the ice box, which is
placed in one corner of the chamber A, as more clearly indicated in
Figure 2, and consequently may be most conveniently made with a tri-
angular cross section. At each end this ice box is formed with an open
throat a of materially smaller diameter than the ice box, the lowermost
throat being provided with a system of horizontal bars e to support the
mass of broken or fragmentary ice placed within the box. At the lower
end of the said icc box is the shell c of a fan or blower b arranged to
force the air confined within the chamber A through the ice box, cither
This fan or
in an upward or downward direction, as may be preferred.
blower may be operated either by a small water motor or by any other
suitable power. To the upper throat of the ice box is fitted a flaring
hood D, and to the opening a¹ of the fan blower shell C, so as to form as
it were a continuation of the lowermost throat of the ice box, is a
similar hood D'.
In the operation of this apparatus the said fan blower draws the air
into the ice box, for instance, in a downward direction. The throats of
the ice box being of less diameter than the box itself, and centrally
situated at the ends thereof, the air is caused to pass through the mass
of ice at the central part of said mass, and is kept from the outer or cir-
cumferential portions, where it would be likely to pass between the sides

page_text: Third. The double-throated ice box constructed for use in connection
with the air-moving mechanism arranged in the corner of the closed
room or chamber and in relation to the walls thereof, as herein described
and for the purpose set forth.
Fourth, The combination of the flaring hood or hoods with one or
both of the throats of the double-throated ico box, as herein described.
and for the purpose set forth.
Fifth. The arrangement of the lower throat or opening of the double-
throated ice box at the front or sides of the said box, as shown in
Figure 4, and for the purpose set forth.
Sixth. The door and opening arranged in relation to the lower throat
or opening of the ice box, as shown in Figure 4 aforesaid, and for the
purpose set forth.
In witness whereof, I, the said George Haseltine, have hereunto
set my hand and seal, this Fifteenth day of December, in
the year of our Lord One thousand eight hundred and seventy-
four.
