PROVISIONAL SPECIFICATION.
Improvements in the Lids of Cooking Utensils.
I, Jons FAVEL GREEN of 159 Queen Street, Melbourne in the Colony of
Victoria, Gentleman, do hereby declare the nature of this invention to be as
follows:-
My invention relates to certain improvements in the lids of cooking utensils
with the object of facilitating culinary operations. The lids as improved by me
are so arranged that when the contents of the vessel boil and emit steam, the
latter will indicate its presence by vibrating a certain part of the lid, thus
informing the cook of the fact.
Secondly, the lid is so arranged that when it is required to pour out from the
vessel any liquid contents, that operation can be performed by tilting the vessel
in the usual way but without first removing the lid, the latter automatically
opening itself.
Thirdly, provide a strainer in combination with the lid in such a manner
that during the pouring operation the liquid passes through the strainer.
My lid therefore performs automatically several useful operations which are now
usually effected for the greater part by hand and less conveniently. The frequent
lifting off of the lid to examine the contents, and the risks of scalding or burning
are obviated.
In my invention a segment or part of the lid of any convenient size is connected
to the remainder by hinges instead of being integral with it.
The vertical rim running round under the circumference of the segment is
however left connected to the rest of the rim of the lid and therefore is disconnected
from said segment or part
A strainer of perforated sheet metal, or of other suitable description, is soldered
or affixed to the rim, beneath the said segment and to the said remainder of the
lid on the under side of the latter.
The segment is made to fit the rim of the utensil easily to allow free movement
on its hinges when effected by steam or other pressure or by gravity.
The remainder of the lid is adapted to grip the utensil firmly so that there may
be no danger of the lid falling off when pouring is going on.
I provide several clutches or spring projections in the rim of the said remainder
or main part of the lid as a means of preventing any falling off as aforesaid.
Dated this 29th day of August 1892.

COMPLETE SPECIFICATION.
Improvements in the Lids of Cooking Utensils.
I, JOHN FAVEL GREEN of 159 Queen Street, Melbourne in the Colony of
Victoria, Gentleman, 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 :-
My invention relates to certain improvements in the lids of cooking utensils
with the object of facilitating culinary operations. The lids, as improved by me,
are so arranged that, when the contents of the vessel boil and emit steam, the

latter will indicate its presence by vibrating a certain part of the lid, this informing
Secondly, the lid is so arranged that, when it is required to pour out from the
vessel any liquid contents, that operation can be performed by merely tilting
the vessel in the usual way, but without first removing the lid, the latter
automatically opening itself.
Thirdly,
provide a strainer in combination with the lid in such a manner
that, during the pouring operation, the liquid passes through the strainer.
My lid, therefore, performs automatically several useful operations which are
now usually effected for the greater part by hand and less conveniently.
The frequent lifting off of the lid to examine the contents and the risk of
scalding or burning are obvinted.
In one form of my invention, a segment or part of the lid of any convenient
size is connected to the remainder by hinges instead of being integral with it, and,
in another form, the lid is not divided into two parts but an extra flap or tap is
provided and hinged on as an attachment to the lid itself.
The vertical rim running round under the circumference of the segment is left
connected to the rest of the rim of the lid, and, therefore, is disconnected from
the said segment or part in the first mentioned form of my invention, but not in
the second form.
A strainer of perforated sheet metal or of other suitable description is soldered
or affixed to the rim beneath the said segment and to the said remainder of the lid
on the under side of the latter in the first mentioned form of my invention, and, in
the second form of my invention, the strainer is formed by perforating the lid to
any desired extent.
The segment in the first form of my invention is made to fit the rim of the
utensil easily to allow free movement on its hinges when affected by steam or other
pressure or by gravity, and, in the second form, the hinged flap is made to
completely cover the perforations and be adapted to vibrate in the same way as the
segment would do.
The vertical under rim extending round the lid is adapted to grip the utensil
firmly, so that there may be no danger of the lid dropping off at any time.
Referring to the accompanying drawings
-
Figure 1 shows in perspective the top of a cooking utensil with my improved
lid having an attachment as before referred to;
Figure 2 is a plan view from above of the lid shown in Figure 1.
Figure 3 is a perspective view of the top of a culinary utensil with a lid on,
a part of the utensil and lid being broken away to show my improvements, the lid
being provided with a hinged segment and a strainer as before described.
Figure 4 is a plan view of the lid and pot shown in Figure 3, a part of the
segment of the lid being shown broken away to show the strainer beneath.
:
In these figures, like letters of reference are used on corresponding parts.
A, is the upper rim of the utensil B is the lid, either divided or undivided as
the case may be C is the hinge on the lid D (Figures 3 and 4) is the segment
of the lid attached to the rest by hinge C.
E is the flap or upper lid attached as in Figures 1 and 2 by hinge C to the
undivided lid.
F is the strainer, consisting in the form as shown in Figures 3 and 4 of a separate
attachment, the edges of which are fastened all round to the under side of the
lid B, and consisting, in the form shown on Figures 1 and 2, of a series of
apertures or perforations in the lid itself beneath the space covered by the flap E:
G is the rim of the lid, having means used for keeping the lid tight on the vessel
when the latter is turned up, and when the weight on the inside of the lid or the
force of gravity would, without such provision, cause the lid to fall off. The
means I show in Figure 1 consist of a pair of slots H in the rim G, said slots
being at diametrically opposite points, and being adapted to lock or engage with
two projections K, also diametrically opposed on the inner part of the upper rim A

page_text: of the cooking utensil. It will be evident that, by screwing the lid round slightly
when putting it on the utensil, the pins K will so enter the slots as to prevent the
cover falling off when the pot is inverted.
In the case of the vessel represented in Figures 3 and 4, however, the lid is oval
in form and therefore cannot be screwed round. In that case, I provide other
suitable means, as flat springs at intervals on the rim of the lid, which springs are
adapted to press strongly against the inner sides of rim A, or I may use other
suitable known devices for preventing the lid falling off.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, 1 declare that what
I claim is:-
1. A cooking utensil lid as shown in Figures 1 and 2 of the drawings having a
flap hinged thereon and perforations in the lid under said flap, substantially as
and for the purposes set forth.
2. A cooking utensil lid substantially as represented in Figures 3 and 4 of the
drawings and having a hinge as C, segment as D and strainer as F, as and for
purposes set forth.
