PROVISIONAL SPECIFICATION.
An Improved Cooling or Refrigerating Vessel or Chamber for use
in the Manufacture of Cream, and the Preservation of Cream,
. Milk, Butter, Meat, Fish, and other Perishable Articles.
GEORGE WOOD HOMER of Athelhampton Hall in the County of Dorset Land-
owner and JOHN HAZEL of Dorchester in the County of Dorset Ironmonger do
hereby declare the nature of this invention to be as follows
:-
The invention relates to a new process of regulating the temperature of milk
during the raising of the cream, and protecting the same, as well as meat and other
goods, from injury or contamination from overheated air, flies or dust.
This is effected by means of a vessel of any shape which may be placed in a
similar vessel or tank.
This latter vessel must be of sufficient size to contain the former vessel and allow
of a margin for water or some other fluid or substance, to completely surround the
inner vessel excepting on the top.
Air is
There is a cover to the inner vessel which cover has a flange rim running
upwards and downwards, that part extending downwards coming between the
vessels; the part extending upwards forming a sort of dish on the cover.
introduced into the inner vessel by means of pipes running through the water in
the outer vessel or the cover or any other water before entering the inner vessel
thus completely regulating the temperature of the air which is introduced.
There is a ventilating shaft in the cover which must extend above the level of
the flanged rim of this cover.
When it is considered necessary to create a special current of air through the
inner vessel a-lamp may be attached to the top of this shaft and kept burning as
long as necessary.
Water of the requisite temperature is allowed to run on to the cover and over-
flowing the rim filling the outer vessel thus completely surrounding but not entering
the inner vessel and acting also on the feeding air pipes.
By this invention: during the hottest summer weather any description of goods
may be protected from injury at a most moderate cost.

COMPLETE SPECIFICATION.
An Improved Cooling or Refrigerating Vessel or Chamber for use
in the Manufacture of Cream, and the Preservation of Cream,
Milk, Butter; Meat, Fish, and other Perishable Articles.
GEORGE WOOD HOMER Landowner Athelhampton Dorchester Dorset JOHN
HAZEL Ironmonger Dorchester Dorset 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 :-
The invention relates to a new process of regulating the temperature of milk
during the rising of cream, and protecting the milk during such process from injury
or contamination from overheated air, dirt, insects, excessive cold etc.
The invention may also be used for protecting and preserving meat, fish, or any
other perishable articles.

page_text: The invention may be constructed of wood glass, iron, brickwork, or other
suitable materials.
The drawing of invention sent with this Specification shew it as a cooler made
in an oblong shape for the purpose of raising cream from milk.
A is the inner vessel in which the milk is placed.
Bis the outer vessel in which A is placed.
C is the cover which fits on A.
When putting the invention to work, the outer vessel B is placed on a suitable
resting place. The inner vessel A. is then fixed in position inside B. The milk is
then placed in A. The cover C is then placed on A. This cover C is constructed
with a rim which first dips downwards perpendicularly all round the cover, then
bending outwards for a space of about one quarter of an inch, and then returning
upwards to a level above that of the central portion of cover C. The cover thus
forms a shallow tray, with what may be termed a narrow ditch all round it.
Water of the proper temperature is then poured in the hollow of the cover C.
When the cover Ċ with its ditch is filled, the water overflows, and fills up the space
in vessel B, so as to fill vessel B up to the overflow pipe F with which it is provided.
The vessel B is also provided with a draw off tap G to allow of its being emptied.
On reference to the plan, it will be seen that the hollow part of the rim of
cover C drops down into the water in vessel B so as to completely surround and
waterseal the inner vessel A. Air is however conveyed to the interior of the
vessel A through 2 pipes D D the inlets to which are outside the rim of cover C.
These pipes D D are so placed on the cover C that they are completely covered
with water. The result is that the air passed through these pipes, is raised or
lowered to the same temperature as the surrounding water. An outlet for carrying
off the air from vessel A is provided in the cover C, by means of a tube E which
passes up beyond the level of the cover C.
A double plug I is fitted in the bottoms of the vessels A and B. To draw off
the milk from the vessel A the inner portion of the double plug I is taken out,
and the milk then runs into a bucket, or other receptacle provided for the purpose.
The strainer L is fixed in the vessel A so as to prevent the cream escaping with
the milk. The cream which will then be left in vessel A can be easily removed.
It will be seen on plan that the vessel A stands on legs H H to admit of the free
passage of water underneath.
The handle of plug I also projects high enough through outlet E to admit of
milk being drawn without removing the cover.
The invention can also be used as a refrigerator for meat, game, and other goods,
and can be built in brick, or other suitable materials, on a smaller or larger scale.
Ice, or any suitable liquid or material may be used instead of water.
Should a quicker current of air be required to pass through the creamer, a lamp,
or gas jet may be so placed at the outlet E to increase the current or heat may be
applied to the outlet E in any other way to produce the same effect.
Having now particularly described, and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
I. The process of treating milk for raising cream by protecting from the outer
air by means of water or some other fluid or substance, and at the same time
ventilating the vessel containing the milk with air, the temperature of which may
be regulated.
II. The process of cooling, or preserving milk, fish, meat, or any other
goods by protecting the same from contact with the outer air, by means of water
or other fluid or substance, and at the same time of ventilating the vessel containing
the said milk, fish, meat, or other goods with air, the temperature of which can be
regulated.
III. The combination in an apparatus for setting milk for cream-of a vessel
for holding the milk, an outer vessel containing the water, or other fluid or substance,

page_text: together with a cover so constructed, as to allow the water, or other fluid or
substance to surround the inner vessel on all sides, and on the top and bottom, and
so constructed as to admit a current of air, the temperature of which may be
regulated into the inner vessel, with an outlet for the air as introduced.
IV. The combination in an apparatus for preserving meat, fish, milk, cream,
butter, or other perishable goods of an inner vessel for containing the said goods
with an outer vessel and cover so constructed that water, or some other fluid or
substance shall surround the inner vessel on all sides, including the top and bottom,
and yet admitting of the perfect ventilation of the inner vessel.
