PROVISIONAL SPECIFICATION.
Improved Construction of Cooler or Chill Room for Meat and
other Edibles.
I HENRY JAMES POWELL of 36 High Street, Lewisham, in the County of Kent,
Butcher do hereby declare the nature of this invention which has been partly com-
municated to me from abroad by William Speller of Union Meat Market, Main
Street, Highland Falls, New York, United States of America Meat Salesman and
partly invented by myself, to be as follows:-
The object of this invention is to construct a cooler or chill room that an even
temperature can be kept up for preserving meat and other edibles.
According to this invention the outer and inner walls, floor and roof are made from
boards, or other material the space between the walls being packed with sawdust or
other non-conducting material. The structure is divided into two compartments, the
under one being for the storage of meat and other edibles to be preserved, the upper
one being a pan for containing ice for cooling and keeping cool the air in the under
compartment by constant circulation.
One end of the upper compartment or ice room is boarded up to within a short
distance of the roof of safe, the other three sides being formed with open or lattice
partitions and from, the boarded end an inner or false ceiling is extended at right
angles to about the distance of a third, this being 6 inches lower than the roof so that
warm air coming from the meat room below will pass up between the closely
boarded up partition and the inner wall of the structure over the inner or false roof
to the ice in the pan and pass down again in a cold state through the open partitions
in the three sides into the meat room thereby creating a constantly repeated current
of cold air in the meat room and keeping same in a cold dry state this being the
essential element of the invention.
Double doors are provided (the one sliding) to the meat room so that the cold air
is prevented from rushing out each time the safe is required to be opened to put in
or take out meat etc. The ice chamber is filled from a door in the side and does not
require the same precaution.
The ice pan has a double floor the top or false bottom being a rack or perforated,
they are slightly sloped to prevent water standing in the pan and all water is
carried from the pan by a pipe to the outside of the building to a drip cup (sealed
or trapped) provided at the outer end of the pipe to prevent inrush of air through and
into the structure.

COMPLETE SPECIFICATION.
Improved Construction of Cooler or Chill Room for Meat and
other Edibles.
I, HENRY JAMES POWELL, of 36 High Street, Lewisham, Kent, Butcher, do hereby
declare the nature of this invention which has been partly communicated to me from
abroad by William Speller, of Union Meat Market, Main Street, Highland Falls, New
York, United States of America, Meat Salesman, and partly invented by myself, and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
The object of this invention is, to construct a cooler or chill room in which an even
temperature can be kept for preserving meat and other edibles.
According to this invention, the outer and inner walls, floor and roof are made

page_text: from boards, or other material, the space between the walls being packed with saw-
dust, or other non-conducting material. The structure is divided into two compart-
ments, the under one is the storage for meat, or other edibles to be preserved,
the upper one having a pan for containing ice for cooling and keeping cool the air in
the under compartment by constant circulation.
One end of the upper compartment, or ice room is boarded up to within a short
distance of the roof, the other three sides are formed with open or lattice partitions,
and from the boarded end, an inner or false ceiling is extended at right angles to
about the distance of a third over, this being 6 inches lower than the roof, so that
warm air coming from the meat room below will pass up between the closely boarded
up partition and the inner wall of the structure, over the inner or false roof to the
ice in the pan and pass down again in a cold state through the open partitions in the
three sides into the meat room, thereby creating a constantly repeated current of cold
air in the meat room, and keeping same in a cold dry state, this being the essential
element of the invention.
Double doors are provided (the one sliding) to the meat room, (a sufficient space
exists between the two doors for a person to stand in, so that one door can be closed
before the other is opened), so that the cold air is prevented from rushing out each
time the safe is required to be opened to put in or take out meat etc. The ice chamber
is filled from a door in the side and does not require the same precautions.
The ice pan has a double floor, the top or false bottom being a rack or perforated,
they are slightly sloped to prevent water standing in the pan, and all water is carried
from the pan by a pipe to the outside of the building to a drip cup (sealed or trapped)
provided at the outer end of the pipe to prevent inrush of air through and into the
structure.
Figure 1 of the annexed drawings is a front exterior view of the structure.
Figure 2 is an elevation of the structure with the front of the casing removed.
Figure 3 is a sectional plan through the line ab of Figure 1.
Figure 4 is section through the line c d of Figure 5, which is a sectional plan of
the ice room, Figure 6 being a perspective elevation of same.
The structure is composed of four walls A, B, C, D, provided with vertical joists E,
to which are fixed inner walls F forming chambers to be packed with sawdust, or other
non-conductor of heat to prevent radiation.
At a certain distance upwards within the structure, a series of horizontal joists, or
floor timbers G are arranged, and above these another inside wall H on one side only
and fixed at a certain distance from the wall F by uprights I and reaching nearly to
the ceiling J forms a channel for the free passage of warm air escaping from the
lower, or meat preserving room into the upper part of ice room, said air flowing in
the direction of the arrows and issuing into the ice room, where it becomes distributed
and cooled before passing through between the slats K, which form a communication
between the ice room and the lower part of the preserving room, thereby promoting
constant circulation and evenness of temperature within the preserving room.
The whole of the flooring of the ice room is composed of a pan L, within which a
grating is arranged for the ice to be placed on, the space below the grating serving
for drip water, which can be drawn off by pipe M into a receiver N provided with
an overflow. The pipe M dips into the water collected in the trap N and prevents
inflow of air by the pipe.
P is a door for entry to the ice room, and Q is an inner sliding door leading to the
meat room, there being another door R outside, hinged, to fold and close the opening
where the door Q is placed.
A ceiling S is provided to the preserving room as a baffle, and to compel the air
to travel in the desired direction.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The structure, hereinbefore described and as shown on the annexed drawings,

page_text: consisting of two compartments, having a communication on one or more sides of
the upper compartment for the up flow of warm air to be cooled, and other passages
from the upper compartment to the lower compartment for the passage of
cooled air.
2. The means by which a constant cooling of warm air rising from meat
preserving chamber is effected and a constant supply of the air cooled to the
preserving chamber at a different part, or parts of the structure from that at which
the warm air ascended.
