A Refrigerating Milk Can or
66
Churn."
I, ERNEST ALFRED LANE, of Manor Farm Dairy, Highgate, in the County of
Middlesex, Dairyman, do hereby declare the nature of this invention to be as
follows:-
"
My invention relates to an improvement in the milk cans used for the transport
and retailing of milk and which are commonly known in the trade as ❝ churns
and the invention has for its object to provide means whereby the liability of the
milk to become sour or deteriorated by exposure of the "churn to the heat of the
sun may be avoided.
,"
According to my invention, the "churn" is provided with an internal refrigerating
or ice chamber whereby the milk may be kept at a uniformly low temperature, and
for this purpose the inner cover with which such "churns are usually provided is
made in one with a hollow leg or chamber preferably of cylindrical form and of a
length to extend down nearly to the bottom of the "churn," such chamber being
closed at bottom and provided at top with a closely fitting lid received in a seat in
the said inner cover of the "churn which is provided with a handle whereby the
inner cover and refrigerating chamber may be readily removed when required.
By providing an inner separate chamber for the reception of ice or other
refrigerating medium, the milk may be kept for a considerable time without
suffering deterioration, whether from any external cause or by dilution which
would ensue from immersing ice directly in the milk.

COMPLETE SPECIFICATION.
66
A Refrigerating Milk Can or Churn."
I, ERNEST ALFRED LANE, of Manor Farm Dairy, Highgate, in the County of
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
-
My invention relates to an improvement in the milk-cans used for the transport
and retailing of milk and which are commonly known in the trade as "churns,"
and the invention has for its object to provide means whereby the milk may be
prevented from becoming sour or otherwise deteriorated by exposure of the churn
to the heat of the sun.
Reference is to be had to the accompanying drawing, forming part of this
Specification, which represents a central vertical section of my improved refrigerating
milk-can or "churn."
"
internal
According to my invention the "churn" A is provided with an
refrigerating or ice chamber B whereby the milk may be kept at a uniformly low
temperature. This chamber B is attached to the inner cover or splash" lid C
with which such "churus " are usually provided and is preferably of cylindrical
form and of a length to extend down nearly to the bottom of the "churn," such
chamber being closed at bottom and provided at top with a closely fitting lid D

page_text: received in a seat in the said inner cover or splash lid C of the "churn." A handle c
is provided on the inner cover or splash lid C whereby the refrigerating chamber
may be readily removed when required, and a similar handle d is provided on the
lid D.
In order to prevent the splash lid being lifted from its seat by reason of the
buoyancy of the ice chamber, the splash lid is locked to its seat by means of two
snugs a fixed just above the seat of lid C. The edge of the lid is notched to
correspond to, and give passage to, the snugs so that by turning the lid slightly
round its edge will engage beneath the snugs and it will be securely held down on
its seat.
By providing an inner separate chamber for the reception of the ice or other
refrigerating medium, the milk may be kept for a considerable time without
suffering deterioration by exposure of the "churu" to a warm atmosphere or the
rays of the sun, and the milk is not liable to be diluted by the ice water which
would happen if the ice were immersed directly in the milk.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
.claim is :-
A milk-can or "churn" provided with an ice tube or chamber pendent within it
from the inner cover or splash lid, said chamber being closed by a lid seated on the
inner cover or splash lid, as specified.
