COMPLETE SPECIFICATION.
Improvements in or relating to Refrigerating Meat and other
Edibles.
I GEORGE WILSON of 4 Rutland Road Hammersmith in the County of Middlesex
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 :-
My invention consists in suitably treating atmospheric air so as to deprive it either
wholly or partially of its moisture or water vapour and subsequently causing it to
circulate in the refrigerating chamber or chambers in order that the food contained
therein (especially meat) shall be in a suitably dry state instead of its being in the usual
" soggy "state when taken out of the refrigerating chamber or chambers and
uncongealed for use.
The following will serve as examples for carrying this invention into effect reference
being had to the drawing accompanying this specification.
I cause the air whether forced under pressure or passing direct from the atmosphere
flowing into and circulating within the refrigerating chamber or chambers to flow
through or over sulphuric acid contained in apparatus or I cause the air to flow through
apparatus containing fragments of pumice stone glass or other suitable substances
soaked in or wetted with sulphuric acid; or I cause the air to flow through apparatus
containing chloride of calcium or quick lime.
Fig. 1 is a longitudinal section of an apparatus within which sulphuric acid rests
on trays or shelves. The air enters through the pipe a and flows over the sulphuric
acid along the passages shown by and in the direction of the arrows. b is the exit
pipe for the air leading into the refrigerating chamber or chambers within which the
meat or other food is stored.
The air in flowing over the surfaces of the sulphuric acid is deprived partly or
wholly of the moisture or water vapour contained in it. At c----c pipes with stop
cocks are inserted through the sides of the apparatus for the purpose of drawing
off the sulphuric acid charged with the water absorbed and also for supplying fresh
sulphuric acid. There are also pipes with stop cocks and gauge glasses fitted into
the sides of the apparatus communicating with each tray or shelf for the purpose of
indicating the level of the sulphuric acid.
Fig. 2 is a longitudinal section of an apparatus suitable for charging with fragments of
pumice stone, glass asbestos or other suitable substances soaked or wetted with
sulphuric acid or the apparatus is charged with chloride of calcium or quick lime. In
this apparatus the air enters through the pipe f and flows through the apparatus in the
direction shown by the arrows and through the pipe fi leading into the refrigerating
chamber or chambers containing the meat or other food stored. At h h the
bottom of the apparatus there are doors for the purpose of withdrawing the substances
contained within it.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1st. Treating atmospheric air so as to deprive it wholly or partially of its moisture
or water vapour and then causing it to circulate in the refrigerating chamber or
