GEORGE CLUTTERBUCK Rutland House 1 Queens Road Peckham, S.E.,
Sanitary Engineer and MARY ANN JANE PERRY 3 Cyprus Terrace Underhill
Road East Dulwich, S.E., do hereby declare the nature of this invention to be as
follows:-
Our invention consists in making kettles either with or without well bottoms
which may be of any convenient shape or size either conical inverted conical;
round, oblong, spherical, semispherical or any other shape with a much broader
brim or flange than is usually employed so as to bring a large surface in contact
with the heat and also to provide an expansion box or chamber at the top with a
sealed feed pipe in or near the middle of the vessel together with a small expansion
or water line vent pipe, carried to or near the spout. We make them with as little
vent as may be convenient to avoid the cold air entering the vessel and to prevent
the heat escaping therefrom; as far as practicable we also keep the parts covered
to conserve or utilise as much of the heat as possible. The hood or cover we
sometimes apply to the sides & top or partly or wholly to the top or sides according
to our desire. In adapting our invention for a bronchitis kettle we provide a sealed
feed pipe or chamber outside of the main vessel which allows the attendant to
readily see the water level. We use any ordinary handle but sometimes employ
one hinged which by being placed on one side allows a frying pan or other vessel
to stand over the hot air outlets of hood or cover for cooking a chop, steak, bacon,
eggs, oatmeal, &c. The spouts may be made to screw on to the vessel if thought
desirable. For heating by gas, or oil lamp or patent fire wood or other fuel we
lengthen the outer case or hood. In some cases we use a metal plate with alternate
holes affixed to the wells to catch the heat & utilise it as a heat conductor & also a
lug heat conducting base plate. With a saucepan, stewpan, or other vessel thau a
kettle we employ a cover to part or the whole of the body with or without holes at
or near the top of the cover so as to keep in as much heat as possible. We form
our vessel with as much as possible of its surface in contact with the heat & that
part which is not exposed to the heat we cover or partly cover to prevent loss of
heat by radiation or the cooling influence of the surrounding atmosphere. We do not
confine our invention to any one particular use for which such utensils are usually
employed.
The several parts may be made of any suitable material or materials.

GEORGE CLUTTERBUCK Rutland House 1 Queens Road Peckham S.E.
Sanitary Engineer, and MARY ANN JANE PERRY No. 3 Cyprus Terrace Under-
hill Road East Dulwich S.E. 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 :-
To make our invention more easily understood, we give drawings explanatory of

page_text: the several parts and combinations thereof not confining ourselves to either scale,
size, form or shape. The same letters in each of the drawings refer to similar parts
of our invention.
A. represents body of vessel.
*Pry as far as possible the several parts to saucepans or similar utensils.
The exit pipe H may come into or over the spout or its equivalent as we may
desire.
The seal or feed pipe E may be either fixed or removable. The spouts may be
fixed either at side or top as desired.
The jacket hood or cover D may be made either fixed or movable, for cleaning
or any other purposes. We also make a portable vessel for use with a gas burner,
night light or spirit or oil lamp. We employ the same parts or combinations 2
with large sized vessels for use, as bath heaters, or for boiling water or other
liquids.
The several parts may be applied to vessels for heating or keeping hot, food, or
drink or other fluids, such as a food warmer, or for use by hairdressers or the
purpose of a workmans tea bottle.
We sometimes make a cheaper form of vessel by omitting the hood or cover D.
The handles may be either fixed or removable of any of the usual kinds or may
be hinged.
The seal or feed pipe and the expansion box and expansion pipe may be applied
to the saucepan or other vessel, and will be useful for cooking apparatus on board
ship or such like as it will prevent boiling over or spilling. By bringing the
expansion pipe from the expansion chamber into the spout of the kettle it may
be used as a bronchitis kettle as the spout may then be used for either pouring out
the liquid or for allowing the steam to escape to the bed room or apartment.
To use the kettle as a bronchitis kettle it is only necessary to place a tube on the 3
spout over a rubber ring or its equivilent or by means of a ferrule.
For a kettle for use in front of a fire or similar manner we cover or partly cover
the outside of the vessel, to conserve the heat received by the water, and also to
prevent the cooling by cold air coming into contact with body of the kettle.
Fig. 1. shows a section of our invention, the dotted lines showing the outer case 4
or hood elongated.
Fig. 2. shows a section of our invention for use on a range or kitchener.
Fig. 3. shows a well with broad metal plate or heat conductor.
Fig. 4. shows a plan of heat conductor.
Having now particularly described and ascertained the nature of our said inven- 4
tion and in what manner the same is to be performed, we declare that what we
claim is.
1. The combination with a kettle or like vessels of an expansion box; steam chest
or resovoir at the highest point of such vessels.
2. Together with a seal feed tube either fixed or movable.
3. And with a vent or expansion safety warning pipe at, in, or near the top of
expansion box into or near the spout.
4. And also a hood or cover or partial hood or cover, either fixed to the vessel
or movable.
5. The combination of an expansion box, a seal dip pipe an expansion pipe, 5

page_text: together with a hood or partial hood or jacket, as can be applied to kettles and
such like vessels, practically and substantially as described.
