Improvements in Covers of Saucepans and similar Covers of like
Utensils, for the Purpose of Adapting them to Aot as Strainers
when Liquid is being Poured from the Saucepans or like Utensils,
and of Preventing Bolling Over.
I, RICHARD CLAYTON, Managing Director of The Cannon Hollowware
Company, Limited, of Deepfields near Bilston in the County of Stafford,
Hollowware Manufacturers, do hereby declare the nature of this invention to 'be
as follows:-
:-
This invention has for its objects, to adapt the cover of a saucepan, or the
similar cover of a like utensil, to answer the purpose of a strainer when liquid is
being poured from the utensil, and to prevent boiling over, without the need (in
either case) for raising it or moving it in any degree outwards from the utensil,
and to answer such purposes without it being necessary to place the cover in a
particular position upon the utensil, and without any special preparation of
the mouth or rim of the utensil which may consequently be left quite plain,
as usual.
The above objects are accomplished, according to this invention, by forming the
cover of the utensil with a portion of its flange, extending for any required distance
circumferentially, pressed up or raised throughout its entire width above the plane
of the remaining portion of the flange, and providing a perforation or perforations
through the rim of the cover immediately beneath the raised portion of the
flange, or in lieu of such perforation or perforations cutting away the portion of
'the rim below the raised portion of the flange or setting backwards or inwards such
portion of the rim.
When a cover prepared in the manner above described is placed upon a utensil,
a space is left between the underside of the raised portion of the flange and the
rim of the utensil, and steam can always escape through the perforation or
perforations of the rim of the cover, or through the space left by cutting away a
portion of such rim, or between the face of the set-back portion thereof and the
rim of the utensil, and thence out between the top of the rim of the utensil and the
underside of the raised portion of the flange of the cover, and thus boiling over is
prevented. Liquid, also may, when the utensil is tilted over, escape therefrom
similarly as the steam escapes, and thus liquid may be strained off from any solid
contents of the utensil, by simply tilting over the utensil while the cover is held
ly thereon to keep back the solid coutents.
It will be obvious that, for the purpose of preventing boiling over, the cover
y be placed with the raised portion of the flange in any position around the
ircumpherence of the utensil; and that, when the cover is to be used for straining
liquid from solid contents of the utensil, the raised portion of the flange
hy be over any part of the rim of the uteusil from which the liquid could
be conveniently poured out if the utensil were uncovered. The passage-way for
the escape of steam, or through which liquid is poured out from the utensil, being
provided entirely by the construction of the cover, the rim of the utensil is left
plain as usual.

Utensils, for the Purpose of Adapting them to Act. as Strainers
when Liquid is being Poured from the Saucepans or like Utensils,.
and of Preventing Boiling Over.
I, RICHARD CLAYTON, Managing Director of The Cannon Hollowware
Company, Limited, of Deepfields near Bilston in the County of Stafford,
Hollowware Manufacturers, 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 for its object to adapt the cover of a saucepan, or the similar
cover of a like utensil, to answer the purpose of a strainer when liquid is being
poured from the utensil, and to prevent boiling over, without the need (in either
case) for raising it or moving it in any degree outwards from the utensil, and to
answer such purposes without it being necessary to place the cover in a particular
position upon the utensil, and without any special preparation of the mouth or rim
of the utensil which may consequently be left quite plaio, as usual.
The above object is accomplished, according to this invention, in the manner
shewn according to varying applications. or modifications thereof by the drawings
herewith, but which all comprise a raised portion of the flange of the cover which
always stands, when the cover is down upon the utensil, some distance clear
thereabovo so as to leave a space between itself and the top of the utensil, in
combination with means by which a passage-way for liquid, or the escape of steam,
is always provided from the interior of the utensil to such space.
Figures 1 to 3; inclusive, each shew a front elevation of a saucepan cover. 'In
each case a portion h of the flange. of the cover is raised, as shewn, above the
plane of the remainder of the flange. In Figure 1 a number of holes k are shewn
as formed through the rim of the cover, in position immediately beneath the
raised portion of the flange. In Figure 2 a single long hole.or slot mis shewn as
formed through the rim.l, in position immediately beneath the raised portion / of
the flange. In Figure 3a length of the entire depth of the rim is shewn as.cut
away to leave a gap m² immediately below the raised portion of the flange. In
this figure, for the sake of clearness of illustration, the line sbewing the bottom of
the portion of the rim which is exactly opposite the gap m² is omitted. Figure 4 is
an elevation of the upper portion of a saucepan B with the cover A shewn by
Figure 1 placed thereon; and Figure 5 is a vertical section, to an enlarged scale,
of one side of the upper portion of the saucepan and of the corresponding side of
the cover shewn by Figure 1, the section through the cover being taken through.
one of the two middle holes k. It will be seen by reference to Figures 4 and 5
that, when the cover is resting upon the saucepan, a space n is left between the
underside of the raised portion of the cover flange i and the top of the saucepan,
and that portions of the holes & are opposite such space, so that without raising
the cover liquid can be poured out through the holes & and space n by simply.tilting
the saucepan as required. The cover may, therefore, be held firmly down upon the
Baucepan, to keep back any solid contents, while the liquid is strained off. The
escape for steam which is always provided by the holes and space n, when the lid
is resting upon the saucepan, prevents the saucepan from boiling over.
will be obvious, also, that the raised portion of the flange i in combination with
the slot m, Figure 2, or in combination with the gap m', Figure 3, will answer the
It

page_text: purpose of the raised portion of the flange in combination with the moles.
Figures 1, 4 and 5.
Figures 6 to 10 inclusive illustrate modifications of the invention which provide
for a passage-way for liquid from the interior of the utensil to the space between
the raised portion of the cover flange and the top or rim of the utensil, without
any portion of the rim of the cover being perforated or cut away for the purpose..
One of these modifications is shewn by Figures 6, 7 and 8, of which Figure 6 is a
front 'elevation of a saucepan cover, Figure 7 an underside view thereof, and
Figure 8 a vertical section, to an enlarged scale, of one side of the upper portion.
of a saucepan and of the corresponding side of the cover, the section through the
cover being taken through the middle of the raised portion h of the cover flange.
The portion p of the rim of the cover is set back, as shewn, uearer to the centre.
of the cover than the remaining portion of the rim, and thus a clear passage-way
is formed between the wall of the saucepan and the face of the set-back portion p.
of the rim, through which liquid can flow to the space n between the raised
portion of the flange and the top of the saucepan, when the saucepan is tilted to.
strain off liquid, and through which steam can escape and so prevent boiling over..
The vertical broken line r, Figure 8, indicates the position of the portion of the
rim which is not set back as described. In lieu of setting back the portion p of
the rim as described, such portion may be formed with vertical corrugations, as
shewn by Figure 9, which form a number of channels, through which liquid may flow
or steam escape. A further modification is shown by Figure 10, which corresponds-
to Figure 8. In this modification, the portion p' of the cover rim which passes along
underneath the raised portion h of the flange is slanted back, as shewn, to give the
required passage-way for liquid and steam to the space n.
It will be obvious that, for the purpose of preventing boiling over, the cover,.
constructed according to either modification in which a portion of the flange is.
raised above the plane of the remaining portion, may be placed with the raised.
portion of the flange in any position around the circumference of the utensil'; and.
that when the cover is to be used for straining off liquid from solid contents of the
utensil, the raised portion of the flange may be over any part of the rim of the
utensil from which liquid could be conveniently poured out if the utensil were
uncovered. The passage-way for the escape of steam, or through which liquid is.
poured out from the utensil, being provided entirely by the construction of the cover,.
the rim or mouth of the utensil is left plain as usual.
The invention has been described above specially with reference to the covers of
saucepans, but it will be obvious, without need for further illustration or description,
that it is applicable also generally to similar covers of like utensils.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A cover for use with a saucepan which has a plain or ordinary rim or mouth,.
or a similar cover for use with a like utensil which has a plain or ordinary rim or
mouth, having a raised portion of the flange which always stands, when the cover
is down upon the utensil, some distance clear thereabove and thus leaves a space
between itself and the top of the utensil, in combination with means by which
communication is ensured, when the cover is down upon the utensil, between the
interior of the utensil and such space, whereby liquid contents can be poured out
from the utensil, by simply tilting it as required, without raising the cover in any
degree from the utensil, and whereby steam can readily escape and thus boiling
over be prevented, substantially as described.
2. A cover for use with a saucepan which has a plain or ordinary rim or mouth.
or a similar cover for use with a like utensil which has a plain or ordinary rim or
mouth, having a raised portion h of the flange i, and either openings k, or an
opening m, or gap m', formed through the portion of the rim which passes.

page_text: immediately beneath such raised portion of the flange, or such portion of the rim
set back or slanted back or corrugated, all substantially as described and shewn by
the drawings herewith.
