New or Improved Means for Keeping Milk or other Liquors Cool.
We, WILLIAM GIBSON, of 2, Warwick Street, Higher Broughton, Salford, Tin-
plate Worker, and JOSEPH ASTON, of 109, Great Clowes Street, Lower Broughton,
Salford, Boot Dealer, do hereby declare the nature of our said invention to be as
follows:-
"
Our said invention consists of an air or fluid tight vessel, large enough to contain
one or more pieces of ice, and to be placed, say in a milk-can or float" for the
purpose of cooling the milk. Such vessel is, by preference, made of sheet metal
and tinned all over to prevent contamination of the milk, and is provided with a
ind having a rubber, cork or like washer for making a joint between said lid
and the top edge of the vessel. Such lid is also provided with two, three or more
clamping screws, which project downwards and pass through snugs or projections
on the sides of the vessel, so that on a nut being applied to each screw, the lid
can be tightly clamped on the vessel and so effectually exclude the milk from
the interior of the vessel, or prevent the ice water reaching the milk.
This device is provided with a small staple and chain, or cord, by which it is
secured or "tethered" down to the floor of the can, and by the length of which
cord it is caused to lie about some six inches or more from the floor of the can,
and thus allow the milk to come in contact with it on all sides. The cord or chain
is provided with a swivel hook, or like device, for allowing the vessel to be readily
removed for cleansing and recharging.
A modification of our invention consists in employing two vessels, or one float and
vessel, and with a cord working over pulleys and designed to rise and fall with
the level of the liquor.
The construction of vessel and means of fixing the lid may vary, but we prefer
the form described.

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement: ---
(S
Our said invention consists of an air or fluid tight vessel, large enough to contain
one or more pieces of ice, and to be placed, say in a milk-can or float"
"for the
purpose of cooling the milk. Such vessel is, by preference, made of sheet metal and
is provided with a lid having a rubber, cork or like washer for making a joint
between said lid and the top edge of the vessel. Such lid is also provided with
two or more clamping screws, which project downwards and pass through snugs
or projections on the sides of the vessel so that on a nut being applied to each
screw the lid can be tightly clamped on the vessel and so effectually exclude
the milk from the interior of the vessel or prevent the ice water reaching the milk.
This device is provided with a small staple and chain, or cord, by which it is
secured or tethered down to the floor of the can, and by the length of which
cord it is caused to lie about some six inches or more from the floor of the can
and thus allow the milk to come in contact with it on all sides. The cord or chain
is provided with a swivel hook or like device for allowing the vessel to be readily
removed for cleaning and recharging.
The construction of the vessel and means of fixing the lid may vary, but we
prefer the form described.
And in order that our said invention may be more readily understood and carried
into practical effect we have hereunto annexed a sheet of drawings and will now
proceed to describe the same with the various figures and letters of reference marked
thereon.
Fig. 1 illustrates a transverse vertical section of our said milk cooler, and Fig. 2
illustrates a vertical section of an ordinary milk tankard shewing the said cooler
applied thereto.
Figs. 3 and 4 illustrates a modified form of fastening for the lid of the cooler.
(A) is a vessel composed of sheet metal tinned all over to resist corrosion and
large enough to hold a considerable amount of ice. When fully charged the
interior of the vessel is sealed by a lid (B) fitted with an elastic packing ring or
washer (C) and any suitable form of clamping device for holding the lid tightly
down upon the vessel.
Such clamping device may consist of two or three screwed parts (E) attached
to the lid, a corresponding number of flanges (F) attached to the vessel, and nuts
(G) applied to each for effectively tightening the lid. It may however, consist of
a swivel lever (H) pivoted centrally, and by a slight turn adapted to engage with
opening (I) in the rising cars (J) fixed to the vessel.
In this case the lid may be made with a slight taper and the "nip" obtained by
the openings (I) being slightly lower than the ends of the lever (H) or such open-
ings be formed slightly on the slope.
In applying the cooler to the ordinary milk tankard shewn in Fig. 2 we provide
the chain (K) and swivels (L) and thereby cause the cooler to occupy a position about
the centre of the mass of milk when the tankard is first filled, and to be entirely
submerged until the can is about half empty whilst for the remaining, portion it
sinks with the level.
For cleaning or charging the cooler the chain is readily dis-connected.
As applied for cooling milk contained in earthenware mugs and like vessels we
dispense with the chain and add a leaden or metal block preferably inside the
cooler as seen in Fig. 1.
Having thus 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:-
1: A device for cooling milk consisting of a vessel adapted to hold ice, a tight

page_text: fitting lid and means for clamping said lid, and with (or without) a chain or the
like for securing said vessel to the floor of the tankard, substantially as set forth
and illustrated on the accompanying drawings.
