Improvements in Kettles and other Culinary Boiling Utensils.
We, ISAAC EVANS of 16 Fisher Road, Birkdale, in the County of Lancaster,
Broker, and HAROLD MCKENZIE SPEAKMAN, of 63 Eastbourne Road, Birkdale,
aforesaid, Traveller, 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 has reference more particularly to kettles for boiling water; but
it also has reference to other vessels or utensils used for domestic and culinary
purposes, in which liquids, or liquids containing solids, are boiled.
The object and effect of the present invention is to provide a kettle of the kind
referred to, by which when the water is boiled, under no circumstances will it boil
over through the spout, or otherwise, as constantly happens with ordinary kettles;
and it also has for its object and effect to obviate the liability of scalding of the
hand, or causing inconvenience when the kettle is handled and used, by the escape.
of steam from the lid or upper part. This invention, however, also relates and has
for its object, to prevent the boiling over of liquids, and the objectionable results
and effects, from ordinary saucepans, and other similar culinary articles, in which
liquids, or liquids containing other matters are boiled.
A kettle according to this invention, partly in section, is shewn in Figure 1.
Figure 2 shews a saucepan and lid according to this invention; and Figure 3
shews the lid in detail.
In the kettle shewn in the drawings, a is its body, and 6 the ordinary pouring
spout, which, substantially, are the same as in an ordinary kettle; then, according
to this invention, we provide upon the upper part of the kettle, and near the side,
a tube e carried up and bent round, with its outlet directed away from the handle d
of the kettle, as shewn, the size of this tube being such that it will carry away all
the steam from the kettle as fast as it is generated, and so prevent, practically, the
pressure within the kettle being raised above that of the atmosphere. All the
steam that escapes from the kettle passes through the tube c, the lid being
imperforate, i.e. without holes or escape apertures. By this tube being at the
uppermost part of the kettle, any and all the steam formed is at once relieved;
and it discharges from the tube, and in a direction away from the handle, and
downwards, as shewn; thus the escaping steam cannot reach the hand when it is
upon the handle d, but is directed away from it, and under all circumstances the
hand will not be scalded, or the handling of the kettle inconvenienced, by escaping
steam. Also, the pressure being thus relieved by the tube c, the discharge of
water, or boiling over through the ordinary spout b of the kettle is rendered
impossible.
A further feature of construction shewn in this kettle consists in specially
providing an annular chamber f at the upper part of the body a of the kettle, by
carrying down around the aperture in which the lid fits, an internal pendant flange h
of considerable depth, say about of an inch from the roof of the aunular chamber;.
whilst the bottom of the lid itself is carried down to about the same depth, and is
closed by the plate i, so that no steam can collect or accumulate under the lid e,
but all has to pass to the annular chamber f, which forms a spieces of collecting
trap or chamber for the stean, whence it is carried off by the tube c.

page_text: In the saucepan and lid shewn in Figures 2 and 3, the steam discharge tube o is
similar to that shewn in the kettle in Figure 1, and is placed on the upper part of
the lid e, while the lid itself (which is, say, of metal) is carried down at h, making
a ring, the bottom of which is closed by the plate i. By this construction, in this
case the annular steam collecting chamber is provided within the lid itself, and
all the steam is carried off therefrom by the tube c.
In some cases, as shewn in Figure 2, the lip or upper edge al of the saucepan a
is made in the form of an outwardly extended annular recess, in which recess the
vertical flange of the lid e fits. By this construction, the part a being cylindrical,
and corresponding with the lid flange, the steam or water is prevented from getting
bebind such flange, and all steam passes directly up into the annular chamber f, and
away by the tube c.
By these constructions, formations, and parts the objects and effects above specified
are attained.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A kettle having at its roof or upper part an annular chamber for the collec-
tion of steam, and a steam escape tube thereon; substantially as and for the purposes
set forth.
2. A kettle having at its roof or upper part, an annular chamber for the collec-
tion of steam; a lid closed at its bottom making a flush surface between the inner
walls of said chamber when the lid is in position; and a steam escape tube in said
chamber; substantially as and for the purposes set forth.
3. A kettle having upon its roof or upper part, a steam escape tube, c, arranged
and adapted to operate substantially as set forth, for the purposes specified.
4. A kettle having the improved constructions or parts particularly as set forth
with reference to and shewn in Figure 1 of the drawings.
5. A saucepan or like utensil lid having a steam escape spout, c, arranged on its
side, and adapted to operate substantially as set forth.
6. The saucepan or like utensil lid having an annular chamber f, and a tube or
spout, c, thereon for carrying, off steam therefrom; substantially as set forth.
7. The improved saucepan or like utensil lid with steam escape tube or spout c,
and saucepan body with the upper ledge a'; substantially as and for the purposes
set forth.
