Improvements in or relating to Apparatus for Airing and Cooling
Milk and other Liquids.
A communication from H. C. PETERSEN & Co, of 8 Industribygningen, Copenhagen,
in the Kingdom of Denmark, Manufacturers.
I, ALFRED JULIUS BOULT, of 111 Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, 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 apparatus for airing and cooling liquids and especially
applicable for milk, and is so arranged that it can be placed upon an ordinary pail
such as is used for transporting milk.
The accompanying drawing shows a vertical longitudinal section through the
apparatus, placed upon a milkpail. The apparatus consists of a lower cup B which
by means of stays C is connected with a ring R, in or upon which the pail A for
pouring in the milk is placed. The pail A having in its base a central hole, has such
a form that the cooling-apparatus, when in use, can be placed and transported within
it, for this purpose the pail is provided with a handle a.
The lower cup B has below a cylindrical neck D which is placed in the neck of the
pail T, when the apparatus is to be used. A part of the circumference of the space
between the lower cup B and the ring R can be closed by a screen, which when the
apparatus is used in the open field is turned against the wind, so as to act as a shield
and to allow the milk to pass quietly through the apparatus.
In the centre of the lower cup B is placed a hollow vertical tube or cone E, which
support the cooling pans 1, 2, 3, 4 and 5; 1, 3, and 5 of which have their bottoms
upwards, while the bottoms of 2 and 4 are turned downwards. The cooling pans 1,
and 5 have an annular, cylindrical edge or flange, which extends about as much
above as below the bottom, and the underside of which is indented or notched. Above
the points of the teeth, along the connection of the bottom and edge of the cooling-
pans, are formed small holes through which the milk in drops can pass out to the
outer side of the cylindrical flange; down which it passes in separated drops to the
teeth; from thence, the milk in single drops, falls into the cups placed below, either
2 or 4 or B. The cooling pans 2 and 4, have fine holes around the upright part E.
Above the cooling pan 1 is placed an ordinary milk strainer F, through which the
milk from the pail A passes to the cooling apparatus.
When the apparatus is placed over the transport pail the milk is poured in the
pail A, from which through the hole in its bottom and strainer F--it runs down into
the cooling pans 1 and then drop by drop passes out through the holes along the
cylindrical edge of the pan and in single drops from the teeth into the cooling-pan 2.
The milk now, through the holes along the inner edge of this cooling pan, runs down
into the cooling pan 3 from which it falls in drops into the cooling pan 4 and at last
reaches the cooling pan 5 and the lower cup B, through the bottom holes n of which
it-cooled and aired-runs down into the pail T in a thoroughly cooled and aired
condition.
To the bottom of the lower cup B is attached a handle H, by which the apparatus

page_text: may be carried in the pail A. In the hole in the bottom of the pail can be placed a
cock so that the speed of delivery may be regulated.
เ
The number and arrangement of the cooling-pans may of course be varied.
The apparatus has the advantage that it may be easily taken to pieces and cleaned.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent and in what manner the
same is to be performed, I declare that what I claim is :-
:-
•
1. An apparatus for airing and cooling milk and other liquids, consisting of a lower
cup and parts supporting the liquid container, and a number of cooling pans placed
between this lower cup and the liquid container the cooling pans being alternately
convex and concave and having holes for the passage of the liquid alternately at the
outer and inner edges, so that the milk or other fluid supplied from the liquid
container is forced to pass drop by drop from one cooling pan to the other; and
during this passage is aired and cooled, substantially as described.
2. In apparatus of the character described, cooling pans having upwardly coned
bottoms and annular cylindrical flanged edges the lower edges of which are dentated
or toothed, the flanged edges being provided with holes immediately above the
downwardly extending points of the teeth, substantially as described.
3. In apparatus of the character described the combination with the cooling and
draining apparatus of a pail or liquid container adapted to receive the apparatus when
.not in use and for transport purposes, substantially as described.
4. The combination and arrangement of parts constituting the complete airing and
cooling apparatus for milk and other liquids substantially as described and illustrated
in the accompanying drawings.
