Improvements in or relating to the Lids of Saucepans and other
Boiling Vessels.
I, ALBERT WARD, of 42, Newlands Street, Everton, Liverpool, in the County
of Lancaster, Accountant, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to certain improvements in the lids of saucepans and
other boiling vessels, and has mainly for its object to facilitate the straining of
the liquid when poured from such vessels and to prevent or stop their boiling
over.
In carrying the invention into effect, the plan I prefer is to form the flange
of the cover which rests on the top of the vessel when the cover is in place, with
an orifice through which the liquid can flow out from the inside when the vessel
is tilted, yet narrow enough to prevent everything except liquid to escape through
it. This orifice may be made in the flange by severing the metal at the edge
and separating the two folds constituting the flange, so as to form an elongated
narrow orifice, or it may be otherwise made. There is a chamber inside this
cover with which this orifice directly communicates, and part of the wall of this
chamber is perforated or otherwise provided with a straining area at the bottom
allowing liquid to be passed out of the saucepan or steam to escape without re-
moving the lid. The bottom of the chamber is above the normal level of the
liquid in the vessel but preferably below the level when the vessel is full. Inside
the chamber there is a hinged valve or trap which normally closes the perfora-
tions, the valve or trap falling by gravity over the perforations to close them, to
facilitate which it may be weighted, or falling away from the perforations to
open them when the vessel with its cover on is considerably tilted.
The cover may be provided, if so desired, with a handle placed at such an angle
that it converges towards the handle of the saucepan or other vessel, so that the
two handles where they converge can be held in the hand and thus when the
vessel is tilted the handle of the cover can be grasped as well as the handle of
the vessel whereby the cover is held firmly in place and any liability of it falling
off is thus entirely prevented.
If desired this action may be assisted by forming or providing a projection or
projections on the opposite side of the lid to engage the inside face of the mouth
of the vessel. The employment of this handle is however optional, and where it
is omitted a suitable locking or catch device may be employed to act, in con-
junction with the aforesaid projection or projections.
i
In use when the vessel is placed on the fire the hinged valve or trap closes the per-
forations, thus preventing any access of cold air and also preventing the steam
generated from the liquid contents in the vessel escaping, thus ensuring that the
boiling shall take place in the soonest possible time. When boiling commences,
the pressure of the steam raises the trap or valve and the steam escapes through
the perforations and out of the orifice in the flange of the lid, and this takes
place without having to remove the cover. Furthermore, any boiling over of

page_text: the contents is prevented. The tilting of the saucepan or other vessel when
removed from the fire enables the liquid contents to be poured out through the per-
forations and orifice in the lid, leaving the other contents inside which can then
be removed when the lid is taken off..
I have described the above way of carrying my invention into effect but I
wish it to be understood that I do not confine myself, to the exact details set
forth, as these may be altered to some extent without departing from the nature
of my invention. Thus for example instead of placing the orifice in the flange
of the lid, it may be placed on top or in any other suitable position, so long as
it communicates with the: perforated chamber inside the lid, and furthermore this
orifice may be of any suitable shape not necessarily narrow, as the perforations
in the bottom of the chamber ensure the contents being strained, when the
liquid is poured out.

Improvements in or relating to the Lids of Saucepans and other
Boiling Vessels.
I, ALBERT WARD, of 42, Newlands Street, Everton, Liverpool, in the County
of Lancaster, Accountant, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to certain improvements in the lids of saucepans and
other boiling vessels, and has mainly for its object to facilitate the straining of
the liquid when poured from such vessels and to largely prevent or stop their
boiling over.
The invention is best described by aid of the accompanying drawings, in which,
Figure 1 is a bottom plan of a saucepan lid made in accordance with my inven-
tion;
"
Figure 2, an elevation of the lid partly in section shown lifted off the saucepan ;
Figure 3, an elevation of the lid in position on the saucepan;
Figure 4, an elevation of a portion of the lid drawn to a larger scale to show
more clearly the orifice in the flange;
Figure 5, a section of a portion of the lid drawn to larger scale showing the
action of the trap;
Figures 6, 7 and 8 show some modifications in the carrying out of the invention.
In carrying the invention into effect, the plan I prefer is to form the flange a
of the cover which rests on the top of the vessel when the cover is in place,
with an orifice such as b through which the liquid can flow out from the inside
when the vessel is tilted, yet narrow enough to prevent everything except liquid
to escape through it. This orifice may be made in the flange by severing the
metal at the edge and separating the two folds constituting the flange, so as to
form an elongated narrow orifice as shown more clearly in Figure 4;' or it may be
otherwise made.
Figure 7 shows the upper lip or fold of the flange crimped or corrugated to
form a better straining orifice.
There is a chamber cinside this cover with which this orifice directly com-
municates, and part of the wall d of this chamber is perforated or otherwise pro-

page_text: vided with a straining area at the bottom allowing liquid to be passed out of the
saucepan, or steam to escape without removing the lid. The bottom of the cham-
ber is above the normal level of the liquid in the vessel but preferably below the
level when the vessel is full.
Figures 1, 2 and 5 show the perforated bottom d of the chamber c attached to
the lid or cover by means of a hinge e to allow of its being swung open in the
direction of the dotted arc f.(Figure 5) to afford access for cleaning, a pivoted
catch or turn button g being provided to secure it when closed. The strainer d
may however be secured in any convenient way. For instance in Figure 8 it is
shown permanently fixed by soldering or by being made to fit tightly into the
rim. Inside the chamber c there is a hinged valve or trap h which normally
closes the perforations, the valve or trap falling by gravity over the perforations
to close them, to facilitate which it may be weighted, or falling away from the
perforations to open them when the vessel with its cover on is considerably tilted.
The cover may be provided, if so desired, with a handle placed at such an angle that
it converges towards the handle of the saucepan or other vessel, so that the two
handles where they converge can be held in the hand and thus when the vesse!
is tilted the handle of the cover can be grasped as well as the handle of the
vessel whereby the cover is held firmly in place and any liability of it falling off
is thus entirely prevented..
If desired this action may be assisted by forming or providing a projection or
projections on the opposite side of the lid to engage the inside face of the mouth
of the vessel. The employment of this handle is however optional, and where it
is omitted a suitable locking or catch device may be employed to act in con-
junction with the aforesaid projection or projections.
In use when the vessel is placed on the fire the hinged valve or trap h closes
the perforations, thus preventing any access of cold air and also preventing the
steam generated from the liquid contents in the vessel escaping, thus ensuring
that the boiling shall take place in the soonest possible time.
When boiling
commences, the pressure of the steam raises the trap or valve h and the steam
escapes through the perforations and out of the orifice in the flange of the lid,
as shown in Figure 5, and this takes place without having to remove the cover.
Furthermore, any boiling over of the contents is largely prevented. The tilting
of the saucepan or other vessel when removed from the fire enables the liquid
contents to be poured out through the perforations and orifice in the lid, leaving
the other contents inside which can then be removed when the lid is taken off.
I have described the above way of carrying my invention into effect but I
wish it to be understood that I do not confine myself to the exact details set
forth, as these may be altered to some extent without departing from the nature
of my invention. Thus for example instead of placing the orifice in the flange
of the lid, it may be placed on top or in any other suitable position, so long as
it communicates with the perforated chamber c inside the lid, and furthermore this
orifice may be of any suitable shape not necessarily narrow, as the perforations
in the bottom d of the chamber ensure the contents being strained, when the
liquid is poured out.
It is obvious that to cheapen the cost of production the trap may be omitted
(Figures 6 and 8) although it is not preferable to do so as the increased cost of
the trap is very small. In some cases also the perforated bottom d forming the
chamber c may also be omitted and the cover made simply with the straining
orifice, b, in the flange.
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. The improvement in lids or covers for saucepans and other boiling vessels

page_text: which consists in forming a straining or discharge orifice in the flange thereof by
opening the folds of the flange, substantially as herein before described.
.
2. A lid or cover for saucepans and other boiling vessels having an inner cham-
ber formed by a perforated bottom or strainer and a discharge or strainer orifice
affording exit from said chamber through the lid, substantially as hereinbefore
described.
3. In a lid or cover for saucepans and other boiling vessels having a strainer
or discharge orifice, the combination with an inner chamber formed by a per-
forated bottom or strainer in the lid, of a trap or valve adapted to normally close
the perforations of the bottom or strainer but to lift under the pressure of the
steam when the contents of the vessel boil or when the vessel is tilted, substan-
tially as hereinbefore described.
4. In a lid or cover for saucepans and other boiling vessels, the combination of
a straining or discharge orifice b in the flange of the lid, a perforated bottom or
strainer d forming an inner chamber in the lid below said orifice, and a trap or
valve h pivoted to said strainer or perforated bottom substantially as hereinbefore
described.
