for the Manufacture of Ice.
I, FRANK ALBERT SMITH, gentleman, residing at Steelton, in the County of
Dauphin, and State of Pennsylvania, one of the 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 improvements in domestic and other refrigerators and to
devices for the manufacture of ice.
The object of my invention is to provide a cheap and reliable device for
refrigerating purposes for domestic and other uses, by which the articles contained
in the refrigerator is preserved, fresh water reduced to the proper temperature for
drinking purposes, and at the same time the temperature in some one of the.
compartments reduced to the ice forming, or freezing point.
My invention consists of a refrigerator for domestic use, in which the fresh water
which supplies the freezing chamber to dissolve the salts is passed through a tank
and coil of pipe located in the overflow chamber, whereby the excess or overflow of
the cold solution from the freezinig chamber is utilized to accomplish the initial
cooling of the fresh water. My invention consists further in passing the freezing
mixture after it has performed its work in cooling the drinking water, and in the
production of ice, through a coil of pipes arranged within the preserving chamber
of the refrigerator whereby all the units of cold are utilized.
My invention consists further in certain details of construction, which will be
fully described hereinafter and pointed out in the claims.
Referring to the drawing
-
Figure, 1, is a vertical sectional view of my improved apparatus.
Figure, 2, is a horizontal sectional view on the line, x-x, figure, 1.
A, indicates the main body of the refrigerator, which is composed of an outer
wall, B, and an inner wall, C, with an intervening space between the two walls,
which is filled with any suitable nonconducting packing material, D, as is common
in the construction of refrigerators.
The interior of the refrigerator is divided into upper and lower compartments, E,
and, F, respectively, by the horizontal partition, G, the lower portion or com-
partment, F, being provided with a door and shelves, and used as a storage chamber
for meats, fruits, vegetables etc. while the upper compartment, E, is used for
containing the devices and chemicals, which produce the cold or reduced
temperature. H, and, I, are vessels or tanks located in the compartment or

page_text: chamber, E, and made of any suitable material, but.. by preference of a metal
which will not be effected by the chemicals or salts, they are intended to contain
for producing the reduced temperature.
"
The vessel, H, is designed to be used as the freezing or ice forming vessel, and
are provided with suitable cans, K, for holding the pure fresh water which is to be
formed into ice, said cans being provided with flanges, a, adapted to rest on the
edges of recesses formed in the float, b, and by which means the cans, K are held
in position in the freezing mixture, M, contained in the vessel, H. The float is
provided with a central aperture through which the guide rod, a', is passed, the
lower end of said guide rod being secured to the bottom of the vessel; H, and by
which means the cans, K, and float, B, are held in position. N, is a fresh water tank
located in the bottom of the vessel, I, and is provided with a drain pipe, O, and
stop cock, P, through which the cooled water is drawn for drinking and other
purposes, said tank being provided with a fresh water supply pipe, R, which leads
to and connects with a hydrant, or other convenient water supply.
S, is a pipe leading from the bottom or lower portion of the fresh water tank, N,
and extends up to near the top of the vessel, I, and is led down again by a return
bend, to the bottom of the tank, I, where it is led through the walls thereof into
the lower portion of the vessel, H. The pipe, S, at the top of the bent portion is
provided with a stop cock or regulating valve, T, by which the supply of fresh
water to the tank, H, is regulated. V, is an over flow or equalizing pipe leading
from the freezing vessel, H, to the cooling vessel, I, one end of which extends down
into the vessel, I, so as to discharge the cold solution from the freezing vessel, H,
into the cooling vessel, I, near the bottom thereof, and thus utilize the low
temperature of the solution coming through it, in cooling the water in the
tank, N, and pipe, S.
W, is an overflow pipe which enters the cooling vessel, I, near the top and
extends down and through the storing or preserving compartment, F, by a series of
coils, A, and finally out through the side of the refrigerator to a suitable receptacle
from whence the solution is taken to a suitable evaporating apparatus, where the
salts are recovered for further use.
In practical operation the vessels, H, and, 1, are charged with the proper amount
of the cooling or refrigerating salts preferably, nitrate of ammonia and the valve, T,
opened so as to supply the vessel, H, with the proper amount of water to dissolve
the salts, the force of the water, which enters the vessel, H, under pressure, being
sufficient to agitate the salt thus dispensing with any mechanical devices or means
for stirring or agitating the salts.
When the vessel, H, has filled, the over flow passes out through the pipe, V, into
the vessel, I, where the cooling liquid is utilized to reduce the temperature of the
water in the vessel, N, and pipe, S, and in this way the initial cooling of the fresh
water is accomplished by the overflow from the freezing tank, H. When the
solution or overflow from the tank, H, has reached a certain height in the tank, I,
the surplus or over flow is carried off through the pipe, W, and conducted through
the coil of pipe in the compartment, F, and reduces the temperature of the same.
By bringing the pipe, W, into the refrigerating or preserving chamber, F, near
the top thereof, the cooling liquid in its passage therethrough gives off its greatest
cold in the top of said chamber, the cold air settling down into the chamber, F, and
keeping the articles therein contained at the proper preserving temperature. As
a further means of utilizing all of the cold from the vessels, H, and, I, openings, are
formed in the partition, G, directly underneath the vessels or tanks, so that cold air
or refrigerating currents thrown off from the bottom of said vessels, will enter the
chamber, F.
Instead of having a solid partition, G, I may form the same of a series of slats,
or I may secure and support the tanks, H, and, I, in any suitable manner at their
tops, to the casing of the refrigerator, and thus dispense entirely with the partition,
and allow all of the cold air currents coming from the tanks, H, and, I, to settle
down into the chamber, F, and instead of coiling the pipes, A¹, around the sides of

page_text: the chamber, F, I may find it convenient and desirable to simply coil the same in
the top thereof, and by this means, utilize all the units of cold. By closing, or
and
partly closing the valve, T, the water is retained in the pipe, S, and tank, N,
cooled to any desired temperature before it is introduced into the freezing tub, and
by opening the valve, T, fully, the salts are stirred or agitated in the tank, H, to
any desired extent by the force of the current of water.
After the first filling of the tanks or vessels, H, and, I, with salts and when the
cooling or freezing operation is fairly under way, the freezing tub, H, only is
replenished with the salts, the overflow of the cold liquid from this vessel into the
vessel, I, being sufficient to accomplish the initial cooling of the fresh water in the
tank, N, and coil, S.
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 I am
aware that it is not new to cool a body of water by the addition of a salt thereto, bringing
this body of cooled water into contact with the walls of another vessel containing pure
water, and thereby reducing the temperature of the pure water almost to the temperature
of the water containing the salt, then dissolving salt in the pure water previously cooled,
and thus reducing its temperature, by which operation ice can be formed in a vessel
immersed in the second body of water, and which vessel and its contained water are
subjected to the cooling due to the dissolving of the cooling agent in the first as well as
the second vessel, and such I do not claim, but what I claim is :-
1. A refrigerator for domestic and other purposes, in which the fresh water
employed in the freezing chamber to dissolve the salts, is passed through a tank
and coil of pipe located in the overflow chamber, whereby the excess or overflow
of the cold solution from the freezing chamber is utilized to accomplish the initial
cooling of the fresh water, as set forth.
21. In a refrigerator for domestic uses and other purposes, the combination of two
tanks or vessels, filled with a solution of nitrate of ammonia salt, a pipe connecting
said tanks for carrying the overflow from the freezing to the cooling tank or
vessel, and discharging said solution near the bottom of said cooling tank, a fresh
water supply pipe leading from a fresh water tank, located in the cooling tank,
to the bottom of the freezing tank, and a regulating valve located in the fresh
water supply pipe, to regulate the flow of water into the freezing tank, whereby
the fresh water is cooled before it comes in contact with the freezing mixture, and
the solution is agitated or mixed in the freezing tub by the force of the incoming
water, as set forth.
32. In a refrigerator for domestic and other uses, the guide rod, a¹, secured in
the bottom of the freezing tank, in combination with the floating disc, b, and
cans, K, whereby the cans are held in position in the freezing solution, as set forth.
43. In a refrigerator for domestic and other uses, the combination of the two
tanks, H, and, I, placed close together and connected by means of the overflow
pipe, V, with the fresh water tank located in the cooling tank, I, and connected to
the freezing tank, H, by means of the pipe, S, and the valve, T, for controlling
the admission of the fresh water to the freezing tank, as set forth.
4. In a refrigerator for domestic purposes and other uses, the combination of the
devices substantially such as described for the continuous production of cold, with
the over flow pipe, W, and coil, A', located in the preserving chamber of the
refrigerator, whereby all the units of cold are utilized, as set forth.
