Bayswater in the county of Middlesex AN IMPROVEMENT IN OR CONNECTED WITH
LIDS OR COVERS OF SAUCEPANS AND LIKE COOKPOTS
The object of this invention is to perforate one half or other desired portion of
the lid proper and to fit or provide an internal half or other form of screen within
the same, said screen being capable of shutting up the perforations. The
perforations when uncovered prevent the contents or liquor boiling over and solid
food or material can be retained securely within the saucepan while the water is
being strained off

the said Leopold Beral Bertram in the Patent Office on the 4th April 1884.
LEOPOLD BERAL BERTRAM of 5 Colville Mansions (N° 1 Flat) Powis Terrace
Bayswater in the County of Middlesex "AN IMPROVEMENT IN OR CONNECTED
WITH LIDS OR COVERS OF SAUCEPANS AND LIKE COOK POTS
"
The object of this invention is to perforate one half or other desired portion of
the lid proper and to fit or provide an internal or an external half or other form of
screen or shield within or upon the same said screen or shield being capable
of shutting up the perforations. The perforations when uncovered prevent the
contents or liquor boiling over and solid food or material can be retained securely
within the saucepan while the water or liquor is being strained off.
My invention will be clearly understood by the annexed drawings in which
Figure 1 is an internal view of a saucepan or cook pot lid A. with perforations B, B,
over about one half of its surface. C is the screen or shield pivotted at D so that
it can be moved round by the knob or button. E shown in the sectional view
Figure 2 the knob or button being under or within the handle F. In the elevation
Figure 1 some of the holes or perforations are shown covered and some of them
uncovered but the shield C can be turned so as to cover up or to uncover the whole
of the perforations as desired the turning of the shield being effected from the
outside without removing the lid.
Figure 3 shows in perspective the interior of a saucepan lid A with the
perforations B and the shield occupying about a fourth only of the surface but any
portion or the whole of the lid may be perforated the shield being so made that the
perforations may be covered or uncovered by the movable shield as before explained
said shield being always attached as to form part of the article.
Figure 4 represents a kettle lid perforated and similarly provided with an inner
shield operated by a short lever E.
Instead of perforating the lid a piece of wire gauze G may be fitted into the
lid A as at Figures 4 and 5 the shield C being on the outside and capable of
movement to the right or to the left by the lever E or by other convenient means
Figures 6 and 7 show a hinged shield C upon the outside of the lid A the
perforations being in the form of slots concentric to each other. The hinged lid
may be fastened temporarily in position by the catch I if desired or it can be plain.
At Figures 8 and 9 the slots are radii and the shield can be moved by the button
or handle E so as to cover or to uncover any number of the slots as before
explained.
Figure 10 is a perspective view of a lid A in which the slot B is capable of
being covered by a sliding shield C.
Figure 11 is an elevation of a perforated (saucepan) lid whose shield C is of disc
form which can be turned by the handle E.
Figure 12 represents a saucepan or stewpan J with one of my perforated lids A
attached by a hinge at K the shield C being on the inner side as first mentioned.
The lids can be temporarily fixed in the saucepan by any kind of attachment
such as by outside clip pieces K' as at Figure 13 or by internal pins L, L, Figure 14.
The main feature in the invention is the perforated lid provided with a shield
which can move or be moved to cover up or to uncover said perforations as set
forth.
Having now described the nature of my said invention and in what manner the
same is to be performed I declare that I claim
First A perforated (saucepan or cookpot) lid provided with a movable screen or
shield by which the perforations or openings may be more or less covered
or uncovered as described and substantially as shown in the annexed
drawing

page_text: Secondly I claim the combination of a movable shield or screen and a fixed shield
or screen as a saucepan or other cookpot cover as and for the purposes
described and as shown in the several figures on the annexed sheet of
drawings, also any equivalent method of combining and operating on
either the inner or the outer portion of such a cover for covering or
uncovering the passages for the escape of steam or for pouring out the
liquid without absolutely removing the lid from the body as set forth
In witness whereof I the said Leopold Beral Bertram have hereunto set my
hand and seal this Thirty-first day of March in the year of our Lord Ono
thousand eight hundred and eighty four.
