PROVISIONAL SPECIFICATION.
Improvements in the Method of Refrigerating, and in Apparatus
therefor.
I WILLIAM KILLEN of 32 May Street Belfast in the County of Antrim in
Ireland Provision Merchant do hereby declare the nature of this invention to be
as follows:-
My invention relates to the accumulation of refrigeration produced by
refrigerating machines and to the regulation of its use and the prevention of too
great desiccation of the air.
For these purposes I employ a tank raised in a convenient position and filled
with water which is traversed by the pipes conveying the cold brine from a
refrigerating machine and becoming nearly or partially frozen thereby and absorbing
and storing the excess of cold.
Through this refrigerated water I pass a number of pipes or tubes from the top
to the bottom of the tank so that the air will fall down through them and be
reduced in temperature and I furnish such pipes or tubes with plugs or valves by
which I regulate the amount of refrigeration as required.

Improvements in the Method of Refrigerating, and in Apparatus
therefor.
I WILLIAM KILLEN of 32 May Street Belfast in the County of Antrim in
Ireland Provision Merchant 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 the accumulation of refrigeration produced by
frigerating machines and to the regulation of its use, thereby obtaining a more
equable temperature, a reserve of refrigerative capacity and the prevention of too
great desiccation of the air, while inconvenience arising from the breakdown or
stoppage of machinery and the necessity for working the refrigerating machine
continuously are obviated.
For these purposes, instead of cooling the air directly from the pipe containing
cold brine as has hitherto been commonly practised, I employ a tank or trough of
metal or other material, capable of readily transmitting cold, raised to a convenient
position, and filled with water or a mixture of salt and water or other liquid or
mixture which is traversed by the pipe conveying the cold brine from an ordinary
or other suitable refrigerating machine and thereby becomes wholly or partially
frozen and absorbs and stores a reserve of cold.
Through the refrigerated contents of the tank or trough I pass a number of

page_text: vertical metal pipes or tubes, formed in the shape of inverted cones having their
segments cut off, and open at both ends so that the air will descend through them
and be reduced in temperature by contact with them, as well as with the sides of
the tank or trough, which are cooled by the refrigerated contents. I extend such
pipes or tubes through the bottom of the tank or trough and furnish them with
plugs or valves by which I regulate the passage of air through them and the
amount of refrigeration to be applied to the chamber or room, as required; or I
may enclose the whole apparatus in a frame and case having louvres, doors or traps
which can be opened and closed, as required, for the same purpose. I also provide
trays or spouts underneath the vertical pipes or tubes and the sides of the frame or
case to catch any drip.
I may place my improved apparatus above or at the side of the chamber or room
to be cooled, or in another chamber or room in connection therewith.
And in order that my said invention may be more fully understood I shall now
refer to the sheet of drawings hereunto annexed the same letters of reference being
used throughout all the figures to indicate the same or corresponding parts of my
improved apparatus.
Fig. I is a cross section (in elevation) of the apparatus showing the tank or
trough raised near to the ceiling of the chamber or room to be used and filled with
water, mixture or other liquid-the traversing pipe to carry the cold brine from
the refrigerating machine-the vertical pipes or tubes open at top and bottom and
kept in position by stays passing between them and the tank or trough sides and
each other-the trays and spouts beneath to catch drip-the frame or case
furnished with falling traps to regulate the refrigeration of the chamber or room
and a beam for supporting the apparatus-and
Fig. II is a plan of part of the apparatus shewing the bottom of the tank or
trough the traversing pipe--the vertical pipes or tubes stayed to each other and
to the sides of the tank or trough-the sides of the frame or case and the
supporting beam.
a. is the tank or trough. b. is the traversing pipe. c, c, c, are the vertical pipes
or tubes, kept in position by the stays, d, d, d, d. e, e, are trays or spouts for
catching any drip. f is a valve for regulating the passage of cold air from the
vertical pipes or tubes. g. is a frame or case to enclose the apparatus provided
with falling doors, h, h, to regulate the passage of cold air into the chamber or
room. i. is the ceiling and floor above and k, is the beam supporting the
apparatus.
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 I
claim
1. The use, in connection with a refrigerating machine, of a tank or trough of
water, mixture or other liquid and traversing pipe constructed and employed
substantially in the manner and for the purposes herein before described and shown
in the drawings hereunto annexed.
2. The use, in refrigerating apparatus, of vertical pipes or tubes and valves or
plugs constructed and employed substantially in the manner and for the purposes
hereinbefore described and shewn in the drawings hereunto annexed and
3. The combination and arrangement of parts constituting my improved
refrigerating apparatus constructed and employed substantially in the manner and
for the purposes herein before described and illustrated by the drawings hereunto
annexed.
