the nature of this invention to be as follows:-
A cover for a Chamber Pot made of pulp.
The cover is nearly flat on the top and has a flange on the under side. This
flange and the top of the Cover are made of such a size and shape that the Cover

page_text: I, HENRY LEWIS of 3 Saint Peter Street, Saint Albans in the County of Hertford,
Chemist, 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 relates to an improved lid or cover of suitable size and shape to fit
on chamber pots. It may be made of Vulcanite or of compressed wood pulp, or of
thin sheets of wood fastened together, or of solid turned wood of special kinds not
liable to become warped, and capable of being rendered waterproof and non-absorbent
as hereinafter described, or of metal or enamelled iron with the flange or rim lined,"
or faced, with pulp india rubber, waterproofed leather or other suitable substance, the
requirements being that the cover shall be light, unbreakable, as noiseless as possible,
non absorbent and unaffected by saline vapour or moisture.
By preference I employ paper or wood pulp of the kind known as
"steel pulp,"
and now made into bowls and a great variety of articles. In order to render the
cover waterproof and non-absorbent I coat it with a surface of varnish paint, enamel,
or japan, or I immerse it in melted wax. The latter process 1 employ especially for
wood, leather, or other absorbent substances.
My improved cover is circular in shape as will be seen by reference to the accom-
panying drawings, in which Fig. 1 shows a plan and Fig. 2 a section of the cover. It
will be observed that the centre A is slightly depressed so that the outer edge B
forms a flange which is flat or nearly so. This flange is designed to rest on the top
edge of the chamber-pot and the central depression forms a shoulder which provents
the cover from slipping off.
In the centre of the cover is a flat topped knob C, on which the cover can rest
when not in use. If preferred a small groove D may be formed near the edge of the
flange, so as to catch any moisture caused by condensation or otherwise, which may
trickle down when the cover is lifted.
It should be mentioned also that with a view to prevent moisture running off the
cover when turned over, and to assist its falling into the pot when the cover is in use,
the inner surface of the cover is not flat but slightly conical, being about a quarter of
an inch higher in the centre than at the circumference.

page_text: Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is―
1. An improved cover for, chamber pots made of wood pulp, paper pulp or metal, or
of other suitable material, so prepared as to be unbreakable and noiseless or nearly so,
and also to be non-absorbent and unaffected by saline moisture or vapour as herein
described and set forth.
2. An improved lid or cover having a central depression with slightly conical
interior surface, a centre knob, an external flange, with or without an annular groove,
as herein described and set forth.
