PROVISIONAL SPECIFICATION.
Improvements in Sanitary Excreta Pans or Receptacles for Closets,
Night Commodes and Chamber Utensils, and other Vessels with
Air-tight Lids or Covers.
We CHARLES CUNLIFFE of Darwen Street, Blackburn, Tin Plate Worker, and JOHN
DUXBURY of Clifton Street, Blackburn, Baker, both in the County of Lancaster, do
hereby declare the nature of this invention to be as follows:-
We construct our excreta pans or receptacles cylindrical or other suitable shape,
with taper or bell mouths or tops; the lids each consist of a taper edged cover corre-
sponding to the top or mouth of the pan, the periphery of such edge being covered
with an india-rubber or other suitable seating, the lid being secured to the pan by
means of a cross clamp or clasp, its two outer ends engaging with the rims or edges
of the pan, and having a central nut through which the screw passes, the end of the
screw abutting, and being secured in the centre of the lid, the lid is forced down on to
the mouth of the pan which is rendered air-tight. When used indoors for patients
having fever or other contagious diseases, a hollow lid is used charged with disin-
fectants; a valve is placed in the lid under the screw, in such a manner that on
turning the screw in one position it opens or closes the valve allowing the disinfectant
to run into the pan, or closes and shuts it off; or the body of the pan may be inclined
from bottom to the top, that is, larger at the top than at the bottom.
A loose wood seat is provided with recesses to fit the top of the pan and prevent it
from slipping off when used inside the house.

DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation of a night commode, with my improvements applied.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a front elevation of my improved airtight lids as applied to a night
cominode, chamber utensil and the like.
Fig. is a sectional elevation of Fig. 3, enlarged.
A is a night commode, chamber utensil, or other vessel, the body of which is either
straight or taper, or any other suitable shape, and with a flange B, wire ring, hoop,
hooks, or lugs, or other suitable projections fixed to the vessel top; a lid or cover (, to
fit the vessel so as to make it airtight being secured thereto by means of a spring D, and
screwed spindle E; the lid or cover is made with a rim at top and bottom forming a
disinfecting chamber Cand groove to receive an indiarubber ring, band, or other
suitable packing F, such aforesaid groove prevents the ring or packing from coming
off when in use.

page_text: In the lid or cover is a stud G with pin or pins H, to fit in a groove H', at the
bottom of the screwed spindle E, so that the screwed spindle may be operated without
turning the lid or cover.
The spring D is made to come over the top of the vessel with hooks D' at each end;
the screwed spindle is worked with a boss J, attached to the centre of the spring D,
so that when the lid C is placed in position, the hooks D' of the spring Dare then under
either the flange, ring, hoop, or other projections of the vessel, and upon operating
the screwed spindle by means of handle E³, the lid or cover C is forced down, and the
spring D, coming up the screwed spindle, presses the lid or cover C tighter within
the vessel, making same perfectly airtight.
When it is unscrewed, the spring D is so arranged as to lift the lid or cover out of
its place, the same can be made of tin, galvanized iron, wood or any suitable
material.
The lid or cover C also forms a vessel C¹, containing a disinfecting liquid, which
(when the night commode or other vessel has been used) is allowed to pass into the
vessel (so disinfecting same) by turning the scrowed spindle E, which bears against a
stud K, opening a clack valve L; after the said vessel A has been sufficiently disinfected,
the screwed spindle is turned back, and the spring M forces the valve K on to its seat
closing it until again required for disinfection.
The disinfecting liquid is placed in the vessel or cover by means of inlet N, which
inlet is afterwards closed by means of a plug N', having an air hole passing through
the same.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. Night commodes or other such vessels constructed with a circular flange or rim,
projecting outside, to which the lids of same can be secured, such rims forming
strengthening pieces to the vessels, such as shown and described.
2. Night commodes or other similar vessels having indiarubber packed or airtight
lids secured by means of spring and screw to their rims, in the manner and for
the purposes such as shown and described.
3. Night commodes or other vessels having airtight lids, containing a chamber for
disinfecting or other liquids, and valve, operated in the manner and for the purposes
such as shown and described.
