PROVISIONAL SPECIFICATION.
Improvements in or relating to Tea-pots, Kettles, Saucepans, and
the like.
I, PETER GILL of 67, Oakland Street, Widnes, in the County of Lancaster,
Insurance Agent, do hereby declare the nature of this invention to be as
follows:-
In tea-pots, kettles, and other like receptacles as hitherto constructed, the lid is
very liable to fall off when the contents are poured out. To obviate this, I make
the face of the orifice or opening which receives the lid, sloping and not as has
hitherto been the case parallel with the bottom of the vessel.
When the vessel is tilted to commence to decant the liquid, the lid will be
approximately horizontal, and at no time during the emptying of the vessel, need
the lid assume such a position as to cause it to fall off.
In the case of tea-pots, and other vessels in which beverages are infused having
spouts for decanting the liquid, I prefer not to make the perforated strainer at the
bottom of the spout flush with the sides of the pot, but I make it dome shaped.
By this arrangement a larger surface is provided for the liquid to flow through,
and the tea leaves will collect when the liquid is decanted at the base of the dome,
instead of blocking the passage.
In vessels for boiling or heating liquids, tubes may be provided passing through
the body, preferably ascending diagonally from the bottom to the top of the vessel;
or a vertical tube may be provided ascending approximately to the middle, and then
turning in another direction to the top of the vessel. The said vertical tube might
for example ascend to about the middle and then branch off in different directions
to the top, or a coiled tube could be provided, the object of these several arrange-
ments being, to enable the heat to ascend through the said tubes and accomplish
the heating or boiling of the liquid with the least possible expenditure of fuel and
time. The bottom of the vessel may be made conical.
The tubes may be taper, the larger end being at the bottom, so that the heat will
impinge against the sides as it ascends. Their ends may be rivetted or screwed to
the vessel, and by making the tubes taper this is facilitated.
In some cases I propose to provide an alarm, for the purpose of indicating when
the liquid boils. This may consist for example of a steam whistle, the lid of the vessel
being secured sufficiently tightly to enable the steam pressure to sound it. The
whistle could form a safety valve to prevent excessive pressure.

COMPLETE SPECIFICATION.
Improvements in or relating to Tea-pots, Kettles, Saucepans, and
the like.
1, PETER GILL of 67 Oakland Street, Widnes, in the County of Lancaster,
Insurance Agent, 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 :-
This invention relates to certain improvements in teapots, kettles, saucepans and the
like, with the object of rendering such articles more convenient to use and more

page_text: The invention may be understood by reference to the accompanying drawings, in

is a similar section of a kettle constructed in accordance with this
Figure 3 is a plan of Figure 2.
Figure 4 is a sectional elevation of a saucepan embodying some of my improve-
ments.
In teapots, kettles, and other like vessels as hitherto ordinarily constructed, the lid
is very liable to fall off when the contents are being poured out. To obviate this,
I make the face A of the orifice or opening which receives the lid B to slope upwards
towards the spout as in Figures 1 and 2, and not, as has hitherto been the case, to lie
parallel with the bottom of the vessel.
When such a vessel is tilted, during the commencement of the decantation of the
liquid, the lid B will be approximately horizontal, and at no time, during the emptying
of the vessel, need the lid assume such a position as to cause it to fall off. In the case
of a kettle it is preferable to place the lid a little nearer to the back than the front of
the vessel, as in Figure 2.
The raising of the front portion of the opening also tends to prevent the liquid
running over the said front portion when in the act of pouring out the liquid.
In the case of teapots, and other vessels in which infusions are prepared, such
vessels having spouts for decanting the liquid, I prefer not to make the perforated
strainer at the bottom of the spout C flush with the sides of the pot as heretofore, but
I make it dome shaped as at C", Figure 1. By this arrangement a larger surface is
provided for the liquid to flow through, and the tea leaves, or other equivalent
material, will collect, when the liquid is decanted, at the base of the dome C, instead
of blocking the passage to the spout. To still further prevent the choking of the
spout, it is preferable to make the lower portion of the dome without perforations
as at c².
In applying my invention to vessels for boiling or heating liquids, I provide each
vessel with one or more tubes which pass wholly or partly through the body of the
vessel in a more or less upward direction.
In the case of vessels, such as kettles, which are partly covered by a permanent
top D, it is preferable to permit the tubes to pass right through the vessel from
the bottom to the top, either in a direction parallel to the sides of the vessel as
at E, Figure 2, or ascending diagonally as shown in dotted lines at E¹ in the same
Figure. Or a vertical tube may be provided ascending approximately to the middle
of the vessel, and then turning or branching off in one or more different directions
to the top thereof. Or a coiled tube could be provided, the object of these several
arrangements being, to enable the heat to ascend through the tubes and accomplish
the heating or boiling of the liquid with the least possible expenditure of fuel and
time. The bottom F of the vessel may also be made concave as shown in Figures 2
and 4.
In open vessels, such as saucepans, having no permanent top, the tubes may be
open only at the lower end as at E2, Figure 4, the upper closed ends being located
at any suitable distance above the bottom of the vessel. Closed tubes, such as E³,
may also be placed in a kettle or other similar vessel as in Figure 2.
The tubes may be tapered as shown, the larger end being at the bottom, so that
the heat will impinge against the sides as it ascends. Their ends may be rivetted
or screwed to the vessel, and by making the tubes tapered this is facilitated. Other
ways of securing the tubes may however be adopted, such as brazing or soldering.
The tubes and the whole or a portion of the bodies of the vessels may be corrugated
for the purpose of offering a greater heating surface.
The lid of the kettle or other vessel may be provided with an opening G, Figure 2,
for the escape of the steam. It is preferable to form this opening in the handle or.
knob G of the lid and to direct it backwards as shown, so that the escaping steam

page_text: does not heat the handle of the kettle. The steam escaping through this opening also
causes a slight sound which indicates when the kettle is boiling. Or a whistle or
other device capable of emitting sound under the inward pressure of the steam, might
be inserted in the opening G for a similar object. In this case the lid of the vessel
would have to be sufficiently tight to permit the steam pressure to rise to the blowing
off point. The whistle would also, in this instance, act as a safety valve.
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 teapot, kettle, or the like, in which the lid opening or orifice has its face
placed in an inclined position with its front portion at such a distance above its rear
portion, that the lid cannot fall off, even when the vessel is tilted to the extreme
position required for emptying it through the spout, substantially as described.
2. A teapot or other similar vessel for the preparation of infusions, having a dome
shaped perforated strainer located within the vessel at the base of the spout, sub-
stantially as and for the purposes described.
3. A kettle, saucepan, or other like vessel for heating or boiling liquids, having one
or more heating tubes passing through the body of the vessel from the bottom to the
top thereof, substantially as and for the purpose set forth.
4. The improved vessels for heating or boiling liquids, each constructed as a whole
substantially as shown and described.
