page_text: Improvements in Refrigerating Chambers.
I, JOSEPH BEASON, of 348, Oldham Road, Failsworth, in the County of Lan-
caster, Agent, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in refrigerating chambers and has for
its object to provide means whereby an economy in space is effected and the
refrigerating surface and capacity of the chamber generally increased.
To this end I employ as usually an air tight chamber well insulated, preferably
by asbestos.
In this chamber I employ a tank fitting against the sides and one end thereof,
the side of this tank next to the end of the chamber being slightly inclined
whilst the opposite side is curved and diminishes in width from the top to the
bottom.
At a suitable height a loose bottom is arranged in the said tank preferably
in a slanting position upon which a freezing mixture, say ice mixed with salt
is placed and which allows the melted ice to run gradually into the lower part
of the tank which thus has been divided into two compartments. The said
freezing mixture is placed into the said tank from above through an opening
formed in the said chamber provided with a door.
The bottom end of the said lower compartment is furnished with a draw-off
tap passing through the wall of the chamber and the outside of the latter with
a gauge glass communicating with the said tap or another suitable appliance
may be provided whereby the quantity of liquid contained in the said compart-
ment can be readily observed.
I also may employ a thermometer on the said chamber to indicate the tempera-
ture therein without having to open the door.
Below the said tank I employ a loose tray having three compartments two of
which serve to hold a quantity of charcoal or other suitable absorbent adapted
to absorb the moisture or liquids accumulating upon or dropping from the sides
of the said tank caused by the evaporation of the trost thereon if the tempera-
ture should go low. The other or middle compartment of this tray is in the
form of a covered channel adapted to communicate with another channel formed
in the back of the said tank, the upper end of which communicates with a shaft
arranged along the top and the other end of this shaft with a receptacle arranged
inside of the said chamber. This receptacle is divided into two compartments
one of which forms an air shaft and the other being adapted to hold a suitable
quantity of compressed or solidified carbon di-oxide.
The said air shafts and channels serve to circulate air mixed with carbon di-
oxide from the said receptacle, through the refrigerating chamber, which carbon
di-oxide may be used alone as a refrigerating agent or in connection with the
refrigerating mixture in the said tank or the compressed or solidified carbon di-
oxide may be used in any other convenient manner say suspended in the said
refrigerating chamber.

page_text: In connection with the said divided receptacle I may form an opening in the
respective chamber end furnished with a door which gives access too the said
receptacle and may also serve as an air inlet.

Improvements in Refrigerating Chambers.
I, JOSEPH BEASON, of 348, Oldham Road, Failsworth, in the County of Lan-
caster, Agent, 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:-
This invention relates to improvements in refrigerating chambers and has for
its object to provide means whereby an economy in space is effected and the
refrigerating surface and capacity of the chamber generally increased.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Fig. 1 being a front view, Fig. 2 an
end view, and Fig. 3 a longitudinal and Fig. 4 a cross section of my improved
refrigerating chamber.
In carrying out my invention and referring to the figures generally, I employ
as usually an air tight chamber a well insulated, preferably by asbestos b.
In this chamber I employ a tank fitting against the two sides and one end
thereof that is to say, no space is left around the end and sides of the tank for
the purpose of isolating it from the walls of the chamber a and forming an
air space.
The side of this tank next to the end of the chamber a is slightly
inclined whilst its opposite side is curved or also inclined so as to cause the tank
to diminish from the top to the bottom.
At a suitable height a loose bottom d may be arranged in the tank e preferably
in a slanting position, upon which a freezing mixture e, say ice mixed with
salt, is placed and which allows the melted ice to run gradually into the lower
part of the tank which thus has been divided into two compartments. The
said freezing mixture is placed into the tank c from above through an opening f
formed in the chamber a provided with a door f¹.
The bottom end of the lower compartment is furnished with a draw-off tap g
passing through the wall of the chamber a and the outside of the latter with
a gauge glass g¹ communicating with the tap g, or another suitable appliance
may be provided whereby the quantity of liquid contained in the said com-
partment can be readily observed.
I also may employ a thermometer on the chamber a to indicate and be able
to ascertain the temperature therein without having to open the door a¹, as will
be readily understood without illustration.
Below the tank I employ a loose tray h which in some cases may be formed
with three compartments h1, h2, h3, two of which h¹, h serve to hold a quantity
of charcoal or other suitable material adapted to absorb the moisture or liquids accumu-
lating upon, or dropping from the sides of the tank e and caused by the evapora-
tion of the frost thereon if the temperature should fall. The other or middle
compartment h³ of this tray is in the form of a covered channel i adapted to
communicate with another channel 2 formed in the back of the tank C₂ the upper

page_text: end of which communicates across the top of the tank with a shaft k arranged
along the top and the other end of this shaft with a receptacle arranged inside
of the chamber a. This receptacle is divided into two compartments 11, 13, 11 form-
ing an air shaft and the other 2 adapted to hold a suitable quantity of com-
pressed or solidified carbon di-oxide.
The said air shafts and channels serve to circulate air mixed with carbon
di-oxide from the said receptacle, through the refrigerating chamber, which
carbon di-oxide may be used alone as a refrigerating agent or in connection with
the refrigerating mixture in the said tank, or the compressed or solidified carbon
di-oxide may be used in any other convenient manner, say suspended in the
said refrigerating chamber, or placed into the tank in lieu of the ice mixed
with salt.
In connection with the divided receptacle I, I may form an opening m in the
respective chamber end furnished with a door m¹ which gives access to the said
receptacle and may also serve as an air inlet when desired.
In some cases I may disregard the use of the said compressed or solidified
carbon di-oxide and refrigerate the chamber entirely by freezing mixture in the
said tank, in which case the said carbon di-oxide receptacle, air shafts and channels
and the middle compartment in the tray h may be rendered in-operative or be
entirely dispensed with as will be readily understood.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1st. In a refrigerating chamber, a tank a for the reception of refrigerating
mixture fitting against one end and the two sides in the inside of the chamber a,
diminishing in size from the top to the bottom and having an inclined back, all
substantially as and for the purpose set forth.
2nd. In a refrigerating chamber, such as specified in the preceding claim,
the tank in combination with a tray h employed below the same and charged
with charcoal or other suitable absorbent, all substantially as and for the pur-
pose set forth.
3rd. In a refrigerating chamber, such as specified in the preceding claims,
the use of carbon di-oxide in a compressed or solid state, substantially as and in
the manner herein before specified.
