1, JOHN LLEWELLIN, of Haverfordwest, in the county of Pembroke, Churn
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved milk pan chiefly designed for maintaining
milk at a suitable temperature for obtaining the maximum yield of cream.
In carrying out my invention I construct the milk pan of a shallow receptacle
having hollow walls preferably formed in two parts, the bottoms of both of which are
dish-shaped. The space between the two parts of the receptacle is for the purpose of
receiving hot or cold water to allow of regulating the temperature of the milk which
is placed in the inner portion thereby assisting the cream to rise. The water is
introduced through an opening provided with a cover at the side of the outer portion,
and a tap or the like at the middle part of the bottom of the same allows of the
water being drawn off when required.
A tube stopped by a plug is similarly provided in the bottom or centre of the inner
portion, being the milk pan, whereby the milk may be readily drawn off, the cream
falling to the bottom of the pan and conveniently following through the same outlet
or it may be skimmed and removed in the ordinary way.
By this construction a maximum quantity of cream is caused to rise from the milk,
which latter is left in a good condition and both the milk and the cream will keep sweet
for a longer time than in an ordinary pan.

page_text: I, JOHN LLEWELLIN, of Haverfordwest,--in--the County of Pembroke, Churn
Manufacturer, 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 an improved milk-pan chiefly designed for maintaining
milk at a suitable temperature for obtaining the maximum yield of cream.
In order to enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing in which
Figure 1 is a plan,
Figure 2 is a longitudinal section, and
Figure 3 is a transverse section of a milk-pan constructed according to my
invention.
Similar letters in all the figures indicate similar parts.
In carrying out my invention I construct the milk-pan of a shallow receptacle
having hollow walls preferably formed in two parts a and b, the bottoms of both of which
parts are dish-shaped, as shown, towards the centre where they are provided with suitable
outlets c and d respectively. The space e between the two parts a and b of the receptacle
is for the purpose of receiving hot or cold water to allow of regulating the temperature of
the milk which is placed in the inner portion thereby assisting the cream to rise.
The water is introduced through an opening provided with a cover g at the side of
the outer portion a and a tap h or the like on the outlet c at the middle part of the
bottom of the portion a allows of the water being drawn off when required.
A tube i stopped by a plug is provided on the oulet d in the bottom or centre of
the inner portion b or milk-pan, whereby the milk may be readily drawn off.
Within the above tube or passage i of the milk outlet, I place a loose but nicely.
fitting perforated cup k through which, when the plug jis removed, the milk only will
pass out, the perforations being so made that they will prevent or save any cream
from passing through, thereby avoiding the necessity for the usual care and watchful-
ness required by existing arrangements.
When the milk has been all drawn off, the perforated cup k is removed and the
cream will then flow out of the tube i.
Or the cream can be removed by skimming and the milk be afterwards drawn off.

which latter is left in a good condition and both the milk and the cream will keep sweet
for a longer time than in an ordinary pan.
Having now particularly described and ascertained the nature of my said inven-.
tion and in what manner the same is to be performed I declare that what
I claim is :-
The manufacture and use of the improved milk-pan hereinbefore described and
illustrated in the accompanying drawing.
