page_text: I, ALLAN JAMES ENGLISH JAKEMAN, of 20 and 22 Goldsmith Street, Drury Lane,
in the County of London, Engineer, do hereby declare the nature of this invention
to be as follows:-
The invention has for its object an improved construction of apparatus which may
be used to either cool or heat milk and other liquids.
For this purpose I construct of sheet metal a chamber in the form of a hollow
corrugated truncated cone, the corrugations of which run round the cone; the smaller
end of the cone is upwards, and an inlet pipe, to supply either cold or hot water or
steam to the interior of the chamber, is led into the lower end thereof; this pipe rises
to, say, two-thirds or thereabouts of the height of the chamber and is perforated at a
suitable angle; it is also preferably led up close to such corrugations and parallel with
the side of the cone. An outlet. pipe is connected with the upper end of the chamber.
A central stay, preferably hollow, is employed to connect the top and bottom of the
chamber together. On the top of the chamber is a perforated distributing cup, which
receives the liquid to be cooled or heated and distributes it over the exterior of the
charaber. The corrugations are preferably formed nearly horizontal on their upper
sides and with a rather steep incline on their lower sides.
The action of the apparatus is as follows. Cold or hot water or steam is led into
the chamber by the lower pipe and passes through the perforations in the latter to
the inner faces of the corrugations; it is thus caused to circulate around the interior
of the chamber and thereby equalize the temperature of its contents, the overflow
water passes away by the upper pipe. The milk or other liquid to be cooled or heated
is led into the distributing cup at the top of the chamber and flows in a thin film over
the upper corrugation, from which it descends in a gradually thinner film by following
the contour of the corrugations down to the bottom of the chamber where it is
received in a convenient trough or vessel.

I, ALLAN JAMES ENGLISH JAKEMAN, of 20 and 22 Goldsmith Street, Drury Lane,
in the County of London, 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 :—
The invention has for its object an improved construction of apparatus which may 5
be used to either cool or heat milk and other liquids.
My invention is illustrated in the accompanying drawings, in which
Fig. 1 is a sectional elevation of the complete apparatus and
Fig. 2 is a plan of the support for the top of the outlet tube.
a is a sheet metal chamber in the form of a hollow truncated cone having, 1
corrugations a¹ which run round the cone. The corrugated truncated cone is preferably
formed of a number of spun rings having flanges soldered together as shown in
Fig. 1, and the corrugations are preferably formed nearly horizontal on their upper
sides and with a rather steep incline on their lower sides.
The chamber a is provided with an inlet pipe b having perforations 61, to supply 1
either cold or hot water or steam to the interior thereof. This inlet pipe b enters the
chamber a at the lower part and passes up nearly to the top of it, preferably in close
contact with the interior of the corrugations.
A central hollow stay c is employed to connect the top and bottom of the chamber
together. Through this central hollow stay c passes the outlet pipe d, which is 2
supported at its upper end by the plate e having a central conical portion e¹ and
arms e², which rest upon the sides of the chamber a as shown. The outlet pipe d
passes through a plate fattached to the bottom of the chamber a, by which it is
supported at its lower end.
On the top of the chamber is a perforated distributing cup g, which receives the 2
liquid to be cooled or heated and distributes it over the exterior of the chamber a.
The chamber a may have three legs h, or it may be supported in any other suitable
way.
The parts may be connected together by means of solder or in any other convenient
manner.

The action of the apparatus is as follows:-Cold or hot water or steam is led into
the chamber a by the inlet pipe b and passes through the perforations 61 in the latter
to the inner faces of the corrugations a¹; it is thus caused to circulate around the
interior of the chamber a and thereby equalize the temperature of its contents; the
overflow water passes away by the outlet pipe d. The milk or other liquid to be 3
cooled or heated is led into the distributing cup g at the top of the chamber a and
flows in a thin film over the upper corrugation a, from which it descends in a
gradually thinner film by following the contour of the corrugations a¹ down to the
bottom of the chamber, where it is received in a convenient trough or vessel.
Having now particularly described and ascertained the nature of my said inven- 4
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. An apparatus for cooling or heating milk and other liquids consisting of a
hollow corrugated truncated conical chamber a having a perforated inlet pipe b,
outlet pipe d, and distributing cup g, substantially as herein shown and 4
described.
2. In an apparatus for cooling or heating milk and other liquids, the combination

perforations 6¹, a stay c, an outlet pipe d, (said stay and outlet pipe being supported
at their upper ends by a plate e provided with arms e² and at their lower ends by a
plate f,) and a cup g, substantially as herein shown and described.
3. The improvements in means for cooling or heating milk and other liquids
substantially as herein shown and described.
