"IMPROVEMENTS IN KETTLES AND DOMESTIC COOKING VESSELS, AND IN APPARATUS
TO BE USED THEREWITH."
This Invention has for its object improvements in kettles and domestic cooking
vessels, and in apparatus to be used therewith.
I construct kettles and cooking vessels with a pipe or tube passing up through
the bottom and out through the top. This pipe or tube is so arranged that the firo
heat ascends through it, and in this way heat is rapidly conveyed to the interior of
the kettle or vessel, which will boil or cook more quickly and with less fuel than
where, as is usual, the fire heat has access only to the exterior.
To large kettles or cooking vessels I apply two or more of these pipes or tubes.
I also apply around the exterior of the kettle or other cooking vessel, about half
way up the side, an inclined guard or hood which serves to catch the flame and heat
from the fire as it rises. There are perforations in the upper part of the guard or
hood close to the sides of the kettle or vessel. The guard or hood serves to confine
the heat closely to the sides of the kettle or vessel; it draws beneath its lower edge
and passes upwards to the perforations. It is so formed as not to collect the cold
air passing to the chimney.
The guard or hood may be moveable, or it may be permanently fixed to the
exterior of the kettle or vessel.
Instead of the kettle or vessel having a concave or hollow bottom I fix a flat
collar or flange at the bottom close round the pipe or tube; this will check or partly
stop the current of cold air drawn from the room.

page_text: The pipe or tube is only carried to the top of the vessel, not more than half an
inch, so as to receive a small cap or lid on the top after heating to prevent rapid
cooling.
The Invention is applicable to kettles and vessels to be heated over a lamp
as well as to those used over fires. It is also particularly applicable to camp
utensils.

"IMPROVEMENTS IN KETTLES AND DOMESTIC COOKING VESSELS, AND IN APPARATUS
TO BE USED THEREWITH."
This Invention has for its object improvements in kettles and domestic cooking
vessels, and in apparatus to be used therewith.
I construct kettles and cooking vessels with a pipe or tube passing up through
the bottom and out through the top. This pipe or tube is so arranged that the fire
heat ascends through it, and in this way heat is rapidly conveyed to the interior of
the kettle or vessel, which will boil or cook more quickly and with less fuel than
where, as is usual, the fire heat has access only to the exterior. To large kettles or
cooking vessels I apply two or more of these pipes or tubes.
I also apply around the exterior of the kettle or other cooking vessel, about half
way up the side, an inclined guard or hood which serves to catch the flame and heat
from the fire as it rises. There are perforations in the upper part of the guard or
hood close to the sides of the kettle or vessel. The guard or hood serves to confine
the heat closely to the sides of the kettle or vessel; it draws beneath its lower edge
and passes upwards to the perforations. It is so formed as not to collect the cold air
passing to the chimney.
The guard or hood may be moveable, or it may be permanently fixed to the
exterior of the kettle or vessel.
Instead of the kettle or vessel having a concave or hollow bottom I fix a flat collar
or flange at the bottom close round the pipe or tube; this will check or partly stop
the current of cold air drawn from the room. The pipe or tube is only carried to
the top of the vessel, or not more than half an inch above, so as to receive a small
cap or lid on the top after heating to prevent rapid cooling.
The Invention is applicable to kettles and vessels to be heated over a lamp
as well as to those used over fires. It is also particularly applicable to camp
utensils.
In order that my said Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawings hereunto annexed.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section of a small domestic cooking pot provided with its
external guard or hood which serves to draw in and confine the heat to the bottom
and centre tube of the pot. This guard or hood is made of sheet iron or other
material; it passes half way, more or less, up the sides of the pot, and it is perforated
all around the upper edge in order that there may be a free current of heated air
through it. A tube, in this case of a taper form, passes up through the interior of
the pot, it has a broad and stout flange at its lower end. This flange is soldered or
otherwise fastened to the bottom of the pot all around the hole formed in the bottom
for the passage of the tube, and so at this part a considerable substance of metal is
provided to take up and afterwards to diffuse the heat of the fire. The tube
passes out through a hole in the lid of the pot, above which it extends about
half an inch. The top of the tube receives a small cover when the pot is off
the fire so that the pot may not be cooled by cold air ascending through the
tube.
I provide with these pots (and also the kettles hereinafter more fully described)
a short length of pipe, which may be placed as a liner within the tube forming
part of the pot or kettle, to protect the said tube from the heat when the pot or
kettle is but partly filled with water.
Figures 2 and 3 are sections of a kettle, and parts in connection therewith, con-
structed and combined in accordance with my Invention. It is provided with a
filling hole by the side of the central tube; this hole has a lid, and a straining bag
of thin woven fabric is fitted to it to strain out any impurities from the water with
which the kettle may be filled. The kettle handles are jointed so as to turn on one
side when standing over the fire, and are kept cool thereby.
Also this settle is provided with a trap or check to catch and retain the sediment
which results from boiling. The trap or check consists of an inclined shelf attached
to the sides of the kettle at a short distance from the bottom, but with a space or
opening opposite to the spout. The shelf does not reach to the inner tube in the
kettle, but is fixed to a short tube which surrounds the inner or fluo tube, and which
descends to the bottom of the kettle. The sediment deposited on the inclined shelf
descends to its lowest part, and then by the opening left passes beneath it, where it
is retained and is so prevented from mingling with water above, which when.
required for use is poured out clear from the spout after the kettle has been at
rest about 10 or 15 minutes after boiling. The deposit is easily removed from
time to time when the kettle is not in use by turning it backwards, then
bottom upwards each time after using.
Figures 4 and 5 also show a kettle and parts combined therewith, as already
described, differing only slightly in form from that represented in Figures 2 and 3.
In all these cases the outer hood or guard is not permanently fixed to the sides of
the pot or kettle, although this may be done, but the pot or kettle is supported by
hanging brackets, and is so suspended from the upper edge of the guard or hood.
These pots and kettles may very advantageously be used over a lamp and be so
heated.
Figure 6 is a vertical section of a cauldron constructed according to my Invention,
and Figure 7 is an horizontal section of the same. The same system of construction
is preserved, but with some modification. Cocks are provided for drawing off the
contents of the cauldron; one of these communicates with the space over the inclined
shelf forming the trap or check and serves to draw off the clear liquid, and the other
communicates with the space beneath the shelf and serves to draw off the sediment.
With the latter, as is shown by the dotted lines in Figure 7, two pipes perforated on
the underside communicate, and these lead the sediment to the cock. The shelf
plate is in this case made in two parts and moveable, so as to be readily cleaned
when required. The parts of the shelf incline towards the centre, and the space by
which the sediment descends to the underside of the shelf or check is left between

page_text: the two parts of the shelf or check where they come together in the centre. The
upper part of the central or flue tube is in this cauldron protected from the heat by
an iron lining that is of taper form similar to the centre tube or pipe. This short
tube is about one third of the length of the former, and about an inch more or less
in circumference. It is fastened by two hooks or an iron pin. The flue tubo of the
cauldron is protected by a water trough or receptacle surrounding it at the top, and
which serves to retain water in contact with the upper part of the flue tube although
the cauldron may be but partly filled. A filling hole is formed in the lid of the
cauldron by which it can be filled, and through the same opening water may be

provided for the filling hole. A stay is inserted into the interior of the cauldron,
which serves to strengthen it and keep it in form, and also to sustain the central
tube and parts in connection therewith.

purposes and the like the fire may be contained in a portable fire basket of iron
bars; this may be upon wheels or may be carried by a wheeled carriage.
Figure 8 is a vertical section of a cylindrical water boiler constructed according
to my Invention; it differs but in form from the cauldron already described; the
inclined shelf is fixed as in the smaller pots and kettles, but it may be made in two
parts and moveable.
This boiler like the cauldron has a cock to draw off the sediment and another
cock to draw off the clear water.
As olready stated in pots, kettles, cauldrons, or boilers of large size two or more
flue pipes or tubes may be fitted, passing up through the vessel in the manner
shown.
Having thus described the nature of my said Invention, and the manner of per-
forming the same, I would have it understood that I claim the construction of
kettles and domestic cooking vessels with pipes or tubes up through the bottom
and out through the top, and in the combination therewith of external guards or
hoods, substantially as herein described.
I also claim the construction of pots, kettles, cauldrons, and boilers, substantially
as described, and represented in the annexed Drawings.
In witness whereof, I, the said William Peacock Savage, have hereunto set my
hand and seal, this Fifteenth day of July, in the year of our Lord One
thousand eight hundred and seventy nine.
