PROVISIONAL SPECIFICATION.
Improvements in Lids for Saucepans, Stewpans, Milk Churns, and
the like.
I, HENRY DRAKE, residing at 21, Victoria Street, Norwich, House Decorator,
do hereby declare the nature of this invention to be as follows:
-
The object of this invention is to provide suitable egress for steam generated
during the process of boiling within saucepans, stewpans and the like and for
ventilating milk churns and the like. My invention consists of making the
said lids in two parts and forming orifices at various places in the rims of each
part, the said rims fit one within the other, and when the respective parts are
in their normal position the orifices in one rim are opposite the orifices in the
other rim, when it is desired to close the ventilation or stop the egress the upper
part is turned to bring the solid parts opposite the orifices.

Improvements in Lids for Saucepans, Stewpans, Milk Churns, and
the like.
I, HENRY DRAKE, residing at 21, Victoria Street, Norwich, House Painter,
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 fol-
lowing statement: —
The main object of this invention is to provide suitable egress for steam generated
during the process of boiling within saucepans, stewpans and the like and a
means for ventilating milk churns and the like. My invention consists in
perforating portions of the rim of the lid or cover and providing a moveable part
having corresponding perforations in the rim, whereby the vents may be closed
or opened as desired. In carrying out my invention I make the lid in two
parts an upper or lid part and a lower part; the upper part is formed like an
ordinary saucepan lid with portions of the rim perforated; the lower part of
the invention consists of a metal ring or flange having two rims one of the
rims fits within the top of the saucepan, stewpan or the like and the other rim
projects upwards to receive the upper portion of the invention the upper rim
of the lower part is perforated in certain portions to correspond with the per-
forations in the rim of the upper part and is made to fit within the said rim.
The accompanying drawing shews a vertical section of the invention. A.F.G are

page_text: parts of the upper portion and B.D.C are parts of the lower portion. D is the
metal ring or flange, C is the rim that fits within the saucepan or the like, B is
the rim projecting upwards to receive the upper portion, A is the rim of the
upper part fitting within the rim B of the lower part, F is cover attached to
flange rim A, G is the handle, E shows the perforations in the rim A.
The vents are closed by turning the upper part until the perforations in one
rim come opposite the solid portions of the other rim.
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:
1st. The method of providing ventilation for milk churns and egress for steam
through the rims of lids of saucepans, stewpans and the like as specified in my
Specification and shown in the accompanying drawings.
