Improvements in Lids or Covers for Boiling, Cooking, or other
Hollow Vessels for the purpose of Removing Steam, Air, and
Gases therefrom.
I, GEORGE RYDILL, 20, Back Lawson Street, Dewsbury, in the County of York,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention of improvements in lids or covers for boiling cooking or other
hollow vessels has for its object the removal of steam air and gases for the pre-
vention of kettles pans coppers or other vessels more particularly those used in
dwellings from boiling over or other vessels requiring a ventilation, lid or cover
by forming corrugations flutings or beaded outward projections round the internal
rim of the lid or cover and corrugations flutings or beaded inward projections
on and round the external flange of the lid or cover so that steam air or gases may
escape on the underside of the external flange of the lid or cover betwixt the cor-
rugations flutings or beaded outward projections formed round on the underside of
the flange leaving a space for the free exit of steam air or gases when the lid or
cover is placed on the top of a straight top saucepan or other vessel.
The rim of the lid or cover is curved or bent round at its circumference to fit
round the upper projecting edge of the kettle pan or other vessel it is intended to
cover so that the corrugations or flutings round the internal rim while fitting
tight round that of the kettle pan or other vessel allows steam air or gases to pass
out betwixt the corrugations, flutings or beaded projections. By this improved
lid or cover liquid can be poured off without removing any substance from the pan
or removing the lid or cover another advantage is when set aside after using even
if wet, will drain and dry itself as the interior open to the atmosphere through
the corrugations flutings or beaded projections which lid or covers may be made
of tin copper nickel german silver aluminium bronze brass iron steel or other
metal or metallic substances which may be electro-plated glass porcelain earthen-
ware hard vulcanite or other substances moulded cast pressed stamped turned in
a lathe or spun sheet metal for the purpose of producing lids or covers with cor-
rugations flutings or beaded projections in the rims and flanges.
With a view to prevent the lid or cover having a knob or handle from falling
off I make a rivet having a collar round near one end and on placing the
short end of the rivet through a hole made on one side of the internal rim from
the outside and on riveting or brazing the short end of the rivet on the inside
of the rim the longer end of the rivet projects outward and on placing the riveted
side of the internal rim of the lid or cover into the opening of a kettle pan or
other vessel the projecting end of the rivet when the lid or cover is pressed down
shoots under the edge on the inside of a kettle pan or other such vessel.

Improvements in Lids or Covers for Boiling, Cooking, or other
Hollow Vessels for the purpose of Removing Steam, Air, and
Gases therefrom.
I, GEORGE RYDILL, 20, Back Lawson Street, Dewsbury, in the County of York,
Merchant, 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 of improvements in lids or covers for boiling cooking or other
hollow vessels has for its object the removal of steam air and gases for the pre-
vention of kettles pans coppers or other vessels more particularly those used in
dwellings from boiling over or other vessels requiring a ventilation in the lid or cover
by forming corrugations flutings or beaded outward projections round the internal
rim of the lid or cover and corrugations flutings or beaded inward projections
on and round the external flange of the lid or cover so that steam air or gases may
escape on the underside of the external flange of the lid or cover betwixt the cor-
rugations flutings.or beaded outward projections formed round on the underside of
the flange leaving a space for the free exit of steam air or gases when the lid or
cover is placed on the top of a straight top saucepan or other vessel.
The rim of the lid or cover is curved or bent round at its circumference to fit
round the upper projecting edge of the kettle pan or other vessel it is intended to
cover so that the corrugations or flutings round the internal rim while fitting
tight round that of the kettle pan or other vessel allows steam air or gases to pass
out betwixt the corrugations, flutings or beaded projections. By this improved
lid or cover liquid can be poured off without removing any substance from the pan
or removing the lid or cover; another advantage is when set aside after using even
if wet, will drain and dry itself as the interior is open to the atmosphere through,
the corrugations flutings or beaded projections which lids or covers may be made
of tin copper nickel german silver aluminium bronze brass iron steel or other
metal or metallic substances which may be electro-plated glass porcelain earthen-
ware hard vulcanite or other substances moulded cast pressed stamped turned in
a lathe or spun sheet metal for the purpose of producing lids or covers with cor-
rugations flutings or beaded projections in the rims and flanges.
With a view to prevent the lid or cover having a knob or handle from falling
off I make a rivet C (Fig. 1) having a collar round near one end and on placing the
short end of the rivet through a hole made on one side of the internal rim from
the outside and on riveting or brazing the short end of the rivet on the inside
of the rim the longer end of the rivet projects outward and on placing the riveted
side of the internal rim of the lid or cover into the opening of a kettle pan or
other vessel the projecting end of the rivet when the lid or cover is pressed down
shoots under the edge on the inside of a kettle pan or other such vessel.
In the drawings Figs. 1, 2, and 3 are perspective views of lids constructed
according to this invention.
At Fig. 1 A is the top of the lid the outer edge of which is corrugated as shown.
B the downwardly projecting internal ring attached to lid A which is also cor-
rugated. The corrugations of the lid A and internal ring B are preferably arranged
to be in communication with each other whereby channels for ventilation purposes
are formed or provided. C is the rivet,-provided with a small collar C¹-which
acts as a hook for preventing the lid from falling off or out of position.
At Fig. 2 the edge of the lid A and downwardly projecting internal ring B are
shown with beaded projections instead of corrugations. In this arrangement the
rivet C may or may not be dispensed with. It is not shown in the drawings.
At Fig. 3 the lid is constructed the same as at Fig. 1 only without the rivet C.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :-
The construction of lids or covers for boiling cooking or other hollow vessels for
the purpose of removing steam air and gasses therefrom having corrugations
flutings or beaded projections round the internal rim or flange as and for the
purposes herein described and illustrated on the accompanying drawing..
Dated this 15th day of October 1897.
