Liquids Overflowing when in a State of Ebullition.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street,
Manchester, both in the County of Lancaster, and 323 High Holborn in
the County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows :-
The improved method and apparatus which form the object of this invention
are intended to prevent any liquid in a state of ebullition or under treatment from
overflowing from the vessel in which it is contained.
This invention in principle consists of a kind of hollow body in which the
pressure of gas or vapour of the liquid is stored up. This gas, pressing on the
surface of the liquid contained in the hollow body, forces this liquid to rise into
one or more tubes (according to the dimensions of the apparatus, which pass through
the upper part of the hollow body) in order to be discharged into the vessel or
receptacle in which the hollow body is placed, in order to keep calm the liquid
therein contained.
An apparatus is thus formed which prevents the liquid in ebullition, or under
treatment, in the vessel, from overflowing and which may as is evident be employed
for cooking food, and the like.
This improved apparatus is composed of a hollow body having cut away portions
at its lower edges in order to facilitate the passage of the liquid iuto it when it is
in the vessel which contains the water, acid or other liquid which is being boiled
or treated. The bubbles of steam, or gas, which are formed under the hollow
body, are retained between the surface of the liquid and the bottom of the hollow
body in such a way that this liquid, at a given moment, is forced to rise in one or
more tubes fixed in the upper part of the hollow body and dipping down into the
liquid inside the apparatus. The liquid after having risen in the tube or tubes is
distributed over the external surface of. a screen or flange arranged on the hollow
body and, finally, falls back into the vessel containing the liquid, and this process
goes on continuously. This displacement takes place with a rapidity proportionate
to the degree of ebullition, so that an apparatus is thus obtained which works in
a rational manner, in order to prevent liquids in a state of ebullition, for instance,
from boiling over the edges of the vessels (such as saucepans and the like) which
contain them.
The drops falling back into the vessel from the screen or flange, break the
bubbles of gas or steam from the liquid, and owing to this, these bubbles fall back
to the level of the liquid; further in order to regulate the apparatus and to
prevent it from being forced upwards, there are formed on the circumference of
the hollow body at a suitable height, a number of holes by means of which the
excess of pressure of gas contained may escape. These holes are placed according
to the weight of the apparatus at any suitable height. Such is the main principle
of this invention, but it is of course understood that the forms, details, materials
of construction and dimensions of the apparatus may vary, as may be desired,
without departing from the principle of the invention.

page_text: It is also immaterial whether the apparatus be placed resting at the bottom of
the vessel or held in the liquid suspended from a point above it. In the case of
closed vessels, the lid may be employed as a distributing cover, or when the
apparatus is in an open vessel and suspended from above the liquid, and instead of
a distributing cover a rose may be employed.
All these modifications do not interfere in any way with the principle and the
working of the invention but simply relate to the form of apparatus employed.

Improved Method of and Apparatus for Preventing Milk or other
Liquids Overflowing when in a State of Ebullition.
A communication by GUSTAVE GEORGES STEINSIEK, of Vergaville, Lorraine, in
the Empire of Germany, Engineer.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E. of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323 High Holborn in the
County of Middlesex, Civil Engineer do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The improved method and apparatus which form the object of this invention
are intended to prevent any liquid in a state of ebullition or under treatment from
overflowing from the vessel in which it is contained.
This invention in principle consists of a kind of hollow body in which the
pressure of gas or vapour of the liquid is stored up. This gas, pressing on the
surface of the liquid contained in the hollow body, forces this liquid to rise into
une or more tubes (according to the dimensions of the apparatus) which pass
through the upper part of the hollow body in order to be discharged into the vessel
or receptacle in which the hollow body is placed, in order to keep calm the liquid
therein contained.
An apparatus is thus formed which prevents the liquid in ebullition, or under
treatment, in the vessel, from overflowing and which may as is evident be employed
for cooking food and the like.
In order to allow of the invention being better understood, an example is shown
on the accompanying drawings, in which,
Figure 1 shows an elevation of the apparatus ;
Figure 2, a vertical section;
Figure 3 a plan view of the same;
Figures 4, 5 and 6 are modifications in the form of construction of the apparatus.
This improved apparatus is composed of a hollow body a having cut away
portions b at its lower edges in order to facilitate the passage of the liquid into it
when it is in the vessel which contains the water, acid or other liquid which is
being boiled or treated. The bubbles of steam, or gas, which are formed under
the hollow body, are retained between the surface of the liquid and the bottom of
the hollow body in such a way that this liquid, at a given moment, is forced to
rise in one or more tubes c fixed in the upper part of the hollow body and dipping
down into the liquid inside the apparatus. The liquid after having risen in the
tube or tubes c is distributed over the external surface of a screen or flange
arranged on the hollow body as shown in Figures 1 and 2 of the drawing, and,
finally, falls back into the vessel containing the liquid, and this process goes on
continuously. This displacement takes place with a rapidity proportionate to the

page_text: degree of ebullition, so that an apparatus is thus obtained which works in a rational
manner, in order to prevent liquids in a state of ebullition, for instance, from
boiling over the edges of the vessels (such as saucepans and the like) which
contain them.
The drops falling back into the vessel from the screen or flange, break the
bubbles of gas or steam arising from the liquid, and owing to this, these bubbles
fall back to the level of the liquid; further in order to regulate the apparatus and
to prevent it from being forced upwards, there are formed on the circumference of
the hollow body at a suitable height, a number of holes e by means of which the
excess of pressure of gas contained inay escape. These holes are placed according
to the weight of the apparatus at any suitable height. Such is the main principle
of this invention, but it is of course understood that the forms, details, materials
of construction and dimensions of the apparatus may vary, as may be desired,
without departing from the principle of the invention.
It is also immaterial whether the apparatus be placed resting at the bottom of
the vessel, as shown in Figure 1, or held in the liquid suspended from a point.
above it, as in Figure 5. In the case of closed vessels, the lid may be employed
as a distributing cover, see Figure 4, or when the apparatus is in an open vessel
and suspended from above the liquid, instead of a distributing cover, a rose may
be employed as shown in Figure 6.
All these modifications do not interfere in any way with the principle and the
working of the invention but simply relate to the form of apparatus employed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is--
An improved method of and apparatus for preventing liquids overflowing the
vessel in which they are contained, when in a state of ebullition, such apparatus
being formed, arranged and combined substantially in the manner bereinbefore
described and as shown as an example in the accompanying drawings.
