Freezers.
A communication by THE G. F. QUINN REFRIGERATOR COMPANY, of Portland,

America.
I, WILLIAM PHILLIPS THOMPSON F.C.S, M.I.ME, of The Agenor for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster 118 New Street, Birmingham in
the County of Warwick, and 31 High Holborn in the County of Middlesex, Civil
Engineer, 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 a combined refrigerator and freezer,
and more particularly to certain principles of construction which tend to increase
the refrigerating and freezing power and to regulate the degree of temperature.
1. consists in a containing case constructed with suitable air spaces and non-
conducting walls and arranged and constructed interiorally as follows:-Between
the ice bunker and the refrigerating or freezing room is a partition formed by a
series of augular sections arranged oue above the other and forming between each
two sections an open space leading from the refrigerating or freezing room into
the ice bunker, the apex of each section extending above the lowest point of tho
section immediately above it, thus forining between each two sections an inverted
V-shaped open space, the olject of which will be hereafter more fully set forth.
Between the bottom of the ice buuker and the bottom of the refugerator case '18
n series of ice supporting bais placed at short distances apart, and extending from
the lower section of said partition over said ice bars, and thenco to the wall of the
ice bunker is a wire netting to hold small particles of ice and salt.
Underneath
the ice bunker is an inclined drip pan and a trap leading down through the
refrigerating case and a partition which prevents the water from passing through
into the refrigerating or freezing 100m. At the top of the refrigerating room
is a ceiling inclined downwardly away from the ice bunker. The walls of the ice
bunker have a shield with inclined openings therein leading to a cold air space
between the partition and refrigerator case. The object and operation of these
several parts, together with certain other details of construction, will be hereinafter
more fully described.
In the drawings herewith accompanying and making a part of this application,
Figure 1 is a vertical longitudinal section ;
Figure 2 is a horizontal section of the same taken on line x-x.
Same letters refer to like parts.
In said drawings a represents the case proper of this improved refrigerator and
freezer. This case may be made in nuy couvement or desirable way. As at
present constructed, it rests upon the floor and has an outside wall b, dead air
space, interior wall d, insulator e, an space, and inner wall g. It also has
suitable doors leading into the refrigerating 100m and into the ice bunker.
The space formed by the interior wall g is divided into two parts by a partition
formed of a series of sections aanged to form an augle and placed one above
the other, leaving a space between each two sections. These sections have their

page_text: ends supported in any convenient manner against the walls of the case. These
sections are so arranged that the apex of one is higher than the lower extremity
of the one next above it, so that said spaces between each two adjacent sections
form as it were air syphons leading from the icfiigerating room into the ice
bunker 1.
J
To reduce the temperature in the refrigerating 100 below the point of
freezing, it will be necessary to bicak up in some measure the ice in the ice
bunker and mix therewith a quantity of salt to promote rapid melting of the ice.
In order to do this, it is necessary to provide means or openings for the insertion
of an ice breaking tool into the bunkei at levels below the doors m To accomplish
this object, half of each alternate section next to the refrigerating room 18
left out.
At the bottom of the ice bunker is a series of bars n resting upon suitable
supporting bars o. Extending from the inner wall of the lower section downwardly
and over said supporting bars o, and thence to the rear wall of the ice bunker is a
wire netting p which serves to prevent small particles of ico and salt from passing
through Passing over said netting at points directly over said bais n are supple-
mental bais g, upon which the cakes of ice are designed to rest instead of resting
directly upon the netting The netting allows the free passage of water and cold
ai out of the ice bunker into tho drip-pan r beneath. These last are not essential,
but they protect the wire from injury by the cakes of ice. The walls of the ice
bunker une lined with a partitions forming an an space between the partition s
and the interior wall g of the case. This partition has a series of inclined ports u
leading from the ice bunker into said an space. Said air space t leads downwardly
and opens into the lower extremity of the ice bunker, and thence through the
netting into the drip pan.
The drip pan is formed by the two sides and rear wall of the case and a
partition between the drip pan and the refrigerating room. A considerable
portion of the floor of the drip pan is formed by au inclined bottom to extending
from the rear wall downwardly and terminating just before the trap. The tiap
consists of a pipe leading from the drip pan out of the refrigerator case.
Ovel
the head of the pipe is a strainer head y near the bottom of which are pet forations,
through which the sun plus water escapes. The top of pipe 2 is above the top of
the perforatious, thus making the waste pipe airtight aud preventing the escapo
of cold air therethrough.
The top of the refrigerating room inclines downwardly from the partition
between the ice bunker and said chamber, as seen at a Figure 1.
The operation of the improved combined efiigerator and freezer is as follows--
The ice is placed in the bunker though the door m The fineness of the 10e
and the quantity of salt will depend upon the degree of cold it is desired to
attain. The fine the ice is crushed and the greater the proportion of salt, the
more rapid will be the melting and the colder the temperature. The cold air in
the ice bunker passes down through the netting directly and also out through the
ports u and thence through the netting at the bottom of the bunker and thence
under the bunker and into the bottom of the refrigerating room. As the cold
air descends in the bunker, each space becomes as it were a syphon, drawing
the air in the refrigerating room through said spaces into the ice bunker, and
down through the ice and netting. The inclining downward of the parts of the
sections gives a downward motion to the column of air passing through the spaces,
and the apex of each being higher than the lower extremity of the one next above
there will be no drawing of the an houzontally across the bunker. Moreover,
this arrangement prevents any water escaping from the melting ice through said
spaces into the refrigerating room.
When refrigerating only is equn ed, all the sections may be complete, as it will
not be necessary to break the ice after it is placed in the bunker, but when it 18
desired to reduce the temperate below freezing and to keep it at that point for a
considerable time, it becomes necessary once in about twenty four hours to break

page_text: the ice in the bottom of the bunker, because the air at that point gradually freezes
it again into a solid mass at the bottom of the buuker, and the melting becomes in
consequence thereof too slow to induce the required temperature
To facilitate
the rebreaking of the ice in the bottom of the bunker half of the partition sections
next to the rofugerating room are left out, as seen in Figure 1, so that an ice
breaking tool can be inserted between said sections into the bottom of the ice
bunker.
The inclination of the bottom of the drip pan downward and forward towards
the refrigeinting room tends to thow the cold air descending from the bunker
above into the refrigerating room. It also tends to collect the dip in a small
space.
Again, the inclination of the ceiling of the refrigerating 100m tends to throw the
warmer and drier au into the bunke to take the place of the colder and moister
mr which has passed downward towards the bottom of the bunker. Thus a
continual circulation of air is obtained passing from the refigerating room through
the spaces in the partition into the bunker, aud thence through the bottom of the
bunker and back into the refrigerating 100m, cold and dry.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manuer the same is to be performed, as communicated to me by
iny foreign corespondents, I declare that what I claim 15-
