ADOLPH JULIUS LEHMANN 14 Delamore Street Liverpool in the County of
Lancaster Engineer do hereby declare the nature of this invention to be as
follows:-
My invention consists of improvements in Pots and Pans for cooking purposes by
which I prevent the overflow or boiling over of the contents in the said Pots and
Pans from dripping or flowing on to the plates of the cooking range, gas stove, or the
fire. The Pots and Pans I construct in the following manner, I raise one end of the
Pots and Pans higher than the other and cast or fasten an open hollow rim in a
slanting direction around the middle or top of the said Pots and Pans and put at the
lower end of the open hollow rim a receiver for the overflow. I also provide the said
open hollow rim for ordinary Pots and Pans.

Improvements in Pots and Pans for Cooking Purposes.
I, ADOLPH JULIUS LEHMANN, of 14 Delamore Street, Liverpool, in the County of
Lancaster, 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 improvements in pots, sauce-pans, kettles or other similar
vessels, used in boiling and culinary operations. By means of these improve-
ments the dirt, discomfort, and other difficulties arising from the boiling over
of the contents of the said vessels are avoided. Such overflow, in the case of
boiling or cooking over an ordinary fire, produces deposits of soot and ashes which
are distributed about the apartment by the clouds of steam arising from the
liquid flowing into the fire. This, in addition, cools the fire, and checks the subse-
quent boiling or cooking process. Other ovils arising from the overflowing liquid are
unpleasant odours, and cracked plates of the cooking range, gas or other heating
stoves used; or other damage to furnaces, where the latter are employed in boiling.
My invention consists in forming vessels of the above named character, with a
gutter or channel extending around the outer circumference of the same, a little
beneath the top; so that the excess of liquor, when boiling takes place, will flow over
the edge of the vessel into the surrounding channel; from which it may be drained
into a suitable receptacle, or directed away from the fireplace, range, or stove. The
channel may be inclined from the horizontal, and be cast or made solid with, or
otherwise form a part of, the vessel; or it can be made as an appendage, and fitted to
any ordinary vessel in use. In either case, a suitable spout or opening is made, by
means of which the overflow liquid is drained or carried off from the circumferential
channel; and this spout is placed at a convenient part in the channel ; for instance,
at or near the handle of an ordinary saucepan, and beneath the same.
The invention also applies to the vessels used by brewers, distillers, sugar refiners
and others, for boiling purposes; however large they may be. The conducting
channel and spout is attached to, or otherwise forms a part of, the "copper" or vessel
in which the boiling operation takes place; exactly in the same manner as in the
smaller vessels.
In addition to the purpose already named, the channel tends to check the ascent
of the heat which rises around the vessel, and to retain it in contact with the same.
The channel thus acts to conduct an appreciable amount of heat to the vessel;
especially when made of copper; and it thus facilitates the operation of heating
cooking or boiling.
Reference is made to the annexed drawings, in which Fig. 1 is a perspective view
of an ordinary cooking saucepan, a, having the channel b arranged round the circum-
ference of the saucepan a, a little below the top. In front, and beneath the handle,

page_text: is shown a spout c adapted to drain the channel b; which is inclined from the hori-
zontal, towards the spout c, for that purpose. Fig. 2 is a plan, showing the channel b,
with its spout c surrounding the saucepan a as before; the handle being removed to
show the spout more plainly. Fig. 3 represents a section through the side of the
saucepan and the draining channel 8.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A culinary vessel having an exterior inclined circumferential channel, adapted to
receive an overflow of liquid from the said vessel; substantially as described.
2. A circumferential channel or gutter, provided with a drainago spout or opening
from the said channel, and adapted to drain or carry off any liquid flowing into or
placed in the said channel; substantially as described.
3. The combination of a vessel used in boiling or culinary operations, with an
exterior channel or drainage gutter adapted to receive and drain off any liquid flowing
into the same, and to conduct heat to the vessel; substantially as described.
