Complete Specification Left, 25th June, 1891-Accepted, 25th July, 1891
PROVISIONAL SPECIFICATION.
Improvements in Covers or Lids for Coppers and Pans.
I EDWIN COXON, 34 Cedar Road, Sherwood Rise, Nottingham, Card Puncher,
do hereby declare the nature of this invention to be as follows:-
Each cover or lid has its edge or vertical flange slotted in two or more places,
each slot engages with a stud projecting from the interior edge of the copper or
pan to prevent the cover from being turned round.
A segment of each cover is cut away so that ready access may be obtained to
the interior of the vessel beneath.
The orifice so formed may be wholly or partly closed by the following means.
The handle of the cover is provided with a stem on its underside secured to a
semi-circular plate free to slide on the lower side of the cover, half of the semi-
circular plate is perforated with a number of circular holes or slots, which may be
placed by turning the handle to coincide with the open segment in the cover thus
allowing steam or other vapour to escape from the vessel, or to act as a strainer.
Or the handle may be turned to close the segment by the imperforated half of the
semicircular plate. Or the plate may be placed clear of the open segment, by
means of the handle at the option of the attendant.
Dated this Sixth day of May 1891.

Improvements in Covers or Lids for Coppers and Pans.
I EDWIN COXON 34 Cedar Road, Sherwood Rise Nottingham Card Puncher 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:-
Figure 1 shows an edge view of one of my improved covers or lids.
Figure 2 is an underside view showing a semicircular plate perforated with circular
holes to act as a strainer, and
Figure 3 an underside view with a slotted semicircular plate.
The vertical flange of each cover or lid is provided with two or more slots B
"shown at Figure 1" each of which engages with a stud projecting from the
interior edge of the copper or pan on which the cover is placed to prevent the
cover from being turned round.
A segment of each cover is cut away at C as shown at Figure 1 and by dotted
lines at Figures 2 and 3, so that ready access may be obtained to the interior of the
copper or pan beneath it without removing the cover.
The orifice so formed may be wholly or partly closed by the following means:-
The handle D of the cover is provided with a stem on its underside free to
turn in a hole in the centre of the cover, the stem being secured to a semi-
circular plate E lying close to but free to slide on the lower side of the cover.
Half of the semicircular plate may be perforated with a number of circular holes
as shown at Figure 2 or slots as shown at Figures 1 and 3, which may be placed
by turning the handle D to coincide with the open segment in the cover thus

tion and in what manner the same is to be performed I declare that what I
claim is...
