PROVISIONAL SPECIFICATION.
Improvements in Applying Covers to Open-topped Vessels for
Sanitary Purposes.
1, WILLIAM THOMAS SEYMOUR, of High Street, Stockton-on-Tees, in the
County of Durham, Tin Plate Worker, do hereby declare the nature of this
invention to be as follows:-
This invention is applicable to open topped vessels and the like, such as are used
as receptacles for sanitary purposes, or for containing the like offensive matter, such
as sanitary cans, night commodes, slop pails or swill tubs.
The object in view is to provide such open topped vessels with lids or covers
which when placed in position, effectually seal the said vessel so that the offensive
and dangerous gases given off by the contents within cannot escape until the said
lid is removed, the means for effecting this purpose being of a simple character and
readily applicable.
In carrying out my invention I furnish at the upper part or rim of the bucket,
pail or the like open topped vessel an annular trough or recess which is preferably
internal in position. The lid or cover of ordinary construction that is, has the
usual bottom rim or circular strip projecting into the bucket or vessel but instead
of relying upon a good fit between the cover and the rim or neck of the bucket or
vessel and which could not readily be made both gastight and easily removable,
I fill the annular trough with water or other liquid which may be chemically
prepared for the purpose so that the rim of the lid projects into the water or other
liquid to a depth sufficient to seal the gases within. In all other respects both lid
and bucket may be of the usual form and construction of parts.

COMPLETE SPECIFICATION.
Improvements in Applying Covers to Open-topped Vessels for
Sanitary Purposes.
I, WILLIAM THOMAS SEYMOUR, of High Street, Stockton-on-Tees, in the
County of Durham, Tin Plate Worker, 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 is applicable to open topped vessels and the like, such as are used
as receptacles for sanitary purposes or for containing the like offensive matter;
such as sanitary pans, night commodes, slop pails or swill tubs.
The object in view is to provide means in connection with such open topped
vessels by which the lid or cover when placed in position effectually seals the said
wessel so that the offensive and dangerous gases given off by the contents within
cannot escape until the said lid is removed, the means for effecting this purpose
being of a simple character and readily applicable.

page_text: And in order that my invention may be clearly understood and readily carried
into effect, I will now proceed to describe the same with reference to the drawing
hereto annexed in which a part sectional view of a sanitary pan or receptacle
illustrates the improvement constituting my invention, which sanitary pan or
receptacle is intended to be taken as representing receptacles generally to which
my invention is applicable and which of course may vary in form and dimensions
as required to adapt them to the particular use for which they are intended.
In the drawing a is the body of the bucket, pail or the like open topped vessel,
at the upper part or rim of which I furnish the trough or recess which is
preferably internal in position as shewn and is continuous with the rim to which it
is attached. The lid or cover c is of ordinary construction that is, has the usual
bottom rim or circular strip c¹ projecting into the bucket or vessel; but instead of
relying upon a good fit between the cover and the rim or neck of the bucket or
vessel and which could not readily be made both gastight and easily removable,
I fill the trough b with water or other liquid which may be chemically prepared
for the purpose so that when the lid is on its seat the rim el projects into the water
or other liquid to a depth sufficient to seal the gases within. In all other respects
both lid and bucket may be of the usual form and construction of parts, except that
the joint between the rim c and cover c should be made gastight by the use of
solder or otherwise, and that a spout and tap may be attached to the receptacle to
enable the trough or recess & to be filled or emptied without removing the cover
from its seat.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what I
claim is :-
In applying covers to open topped vessels for sanitary purposes, the combination
therewith of a trough or recess filled with water or other liquid into which is
inserted the lid or cover so as to effectually seal the gases within the said vessel,
substantially as hereinbefore described with reference to the accompanying
drawing.
