PROVISIONAL SPECIFICATION.
Improved Means and Apparatus for Cooling Milk.
EDWARD LONG 643 High Road, Tottenham, Middlesex, Dairyman, do hereby
declare the nature of this invention to be as follows:
:-
This invention relates to a closed rectangular shape cooler larger at the bottom
than at the top, made of block tin, or any suitable material, and made to any length
or size to suit the purpose for which it is required.
It is provided at the top with an inlet pipe which is continued nearly to the
bottom of the cooler, and an outlet pipe from the top which takes away the heated
water, thus a constant currant of cold water is continually passing through "the
cooler." The convenient size cooler for a milk churn is two feet five inches in
length.

I, EDWARD LONG, of 643 High Road, Tottenham, Middlesex, Dairyman, 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 certain improved means and apparatus for cooling milk.
To carry my invention into practice, I prepare a conical shaped vessel closed
at bottom, the top being open only to a couple of pipes, one of which leads from
near the bottom, and the other from near the top.
My invention, which I term the simple cooler, is represented in the annexed
drawing, and consists of a water vessel A capable of being placed in a churn B to
occupy a central position therein.
The water is supplied by the pipe C from any source of supply and flows down
the leg D to near the bottom of the vessel A, within which it accumulates and
rises to the outlet pipe E to pass away either to a drain, or it may be a tank for
alter use, or it may flow into another supply pipe similar to the pipe C to feed a
vessel similar to A already placed in a separate churn and so on through the vessels
in a series of churns in proximity the whole of the vessels in the several churns
being then fed from one supply.
I have for the sake of convenience arranged screw sockets or ferrules F, F, on
the cover G of the vessel A for the easy attachment of the pipes C, E, by union
joint collars H, H, with which the free ends of the pipes at I, J, are also provided
for the ready connection of the pipes of the series of vessels. The ends of the
pipes may however be nozzle shaped for the reception of short lengths of rubber
tubing for connecting up either from the supply, or from churn to churn. When
the vessel A (or a series of them) becomes filled, the passage of the supply water
can be nearly shut off, the least quantity being sufficient to cause circulation for
reduction of temperature both of the cooling media and of the milk contained
within the body of the churn or churns.

page_text: By this invention, milk in hot weather can be retained at a preservative
temperature for several days without in any way interfering with its character, or
of separating the fat or nutritious properties.
The vessel A is mainly intended to cool milk and to retain it in bulk such as in
dairies at a low temperature but it will be readily understood that by charging the
vessel A with tepid or slightly warmed water, the invention could be of use in the
winter time to maintain the natural warmth of milk, thus far it would be found of
_ value-to ordinary milk carriers going round with the carts to deliver at dwelling
houses because however strong the frost the milk could be kept in a fluid condition
during the delivery.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The construction and employment of the vessel A with bottom dip supply pipe C
and discharge pipe E arranged for easy attachment to said vessel, and also to
other pipes of similar vessels for the purpose of cooling milk in churns, as set forth.
