PROVISIONAL SPECIFICATION.
Improvements in and relating to Saucepans for Heating and Boiling
Milk and other Liquids.
We, JACOB BROWN and ARTHUR BROWN, both of 33, Downing Street, Ardwick,
Manchester, County of Lancaster, Special Apparatus Manufacturers, do hereby
declare the nature of this invention to be as follows:-
This our invention consists of an ordinary saucepan, or other receptacle, with
the addition of an extra removable inner receptacle which we suspend or hold
in position inside such outer receptacle the handles of such inner receptacle and
We
outer receptacle locking together by ketches, or other suitable means,
make such inner receptacle of smaller dimensions than the outer one and keep
the top or rim of such inner receptacle a suitable distance below the top edge of
the outer receptacle. When continuous boiling is required we perforate such
inner receptacle which therefore allows the liquid to find its level in the two
receptacles. When in the act of boiling the liquid forms a continuous circula-
tion from one receptacle to the other, which obviates the boiling over and burn-
ing of such liquids during the process of boiling. We also add to outside recep-
tacle a band of metal or other suitable substance of a suitable depth leaving a
cavity between such band and top edge of outside receptacle, which cavity can
be left open or can be filled with a non-conducting material, thus keeping the
milk, or other liquids, when boiling from burning on the top edge of such outer
receptacle.

COMPLETE SPECIFICATION.
Improvements in and relating to Saucepans for Heating and Boiling
Milk and other Liquids.
We, JACOB BROWN and ARTHUR BROWN, both of 33, Downing Street, Ardwick,
Manchester, in the County of Lancaster, Special Apparatus Manufacturers, 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 follow-
ing statement:―
Our object is to form a saucepan or the like, which will boil milk and other
liquids without the milk or other liquids burning or "boiling over during the
"

page_text: We accomplish this by using in addition to the ordinary saucepan, an inner
saucepan or receptacle, which is suspended within the ordinary saucepan either
by means of an interlocking handle, or preferably by means of bulges or inden-
tations stamped or impressed into the bottom and sides of either the outer or
inner saucepan, or both, as may be most convenient. The upper edge of the inner
receptacle is kept considerably lower than that of the outer pan and the
inner receptacle is also perforated in one or more places at its lower edge, the
effect of this being, that when in use, a constant circulation of the boiling
liquid is kept up between the two pans or receptacles.
We may also in some cases form the upper edge of the outer pan or receptacle
with a suitable cavity which may be either left empty or filled with a non-
conducting material to prevent the milk, or other liquid from burning on this
outer edge.
Referring to the drawings sent herewith:-
The fig. shows a section of our improved apparatus, a indicating the outer
and the inner pan or receptacle, they are kept apart in this instance by means
of bulges c on the bottom and sides of the inner pan 6 which is also perforated
at d to allow of a free circulation of the milk or other liquid through the two
pans. e indicating cavity for nonconducting material when used.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is-
In pans for boiling milk and other liquids, the combination of an outer and
inner receptacle, substantially as, and in the manner, described and shown
herein before and in the accompanying drawing.
