COMPLETE SPECIFICATION.
Improved Chamber Pot.
I, RICHARD DORING, Workmaster of Rawitsch in the Province of Posen and
Kingdom of Prussia 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:-
Chamber pots are often after nɛe allowed to stand for a considerable length of
time with their contents uncovered, especially by sick people, children, servants etc.,
in consequence of helplessness, carelessness, or laziness.
The smells and vapours that are then developed are not only unpleasant but in
many cases injurious and dangerous from a sanitary point of view.
In order to do away with these disadvantages, I have constructed a chamber pot
with a cover attached to it and capable of being turned back, which must be opened
before use, but after use immediately shuts down automatically and shuts off the
contents, so that no air can escape.
In Figs. 1 and 2 the annexed drawing shows the chamber pot from the side in
section, with the cover opened and closed;
Figs. 3 and 4 give the view from the back and from above to Fig. 1, but with
some variatious in the construction.
The chamber pot consists of the vessel A with handle B, the bottom C attached
to the rim a and the cover D.
The bottom C is attached in such a manner to the rim a of the vessel A, that it
easily moves in a perpendicular direction, but cannot fall off, when the whole
chamber is lifted. This may be done, as drawn in Fig. 1 by a [-shaped ring b,
enclosing the rim a and the bottom C, or as in Fig. 3, by a number of separate
perpendicular projections or flaps c on C, which by means of their pins or screws d,
which pass through at their upper end horizontally and radially catch into the
groove e running round between the rim a and the swelling of the vessel A, or as
in Fig. by lateral horizontal rings or flaps f, in the perforations of which
perpendicular pegs g are guided, bearing the bottom C, or in some other suitable
manner.
Between C and the bottom h of A there is arranged a spring-mechanism,
consisting, as is drawn, of a large spiral spring or of several small springs arranged
on the surface or on the circumference of the bottom Calongside of each other, or
of plate-springs, india-rubber, air-cushions, india-rubber buffers or balls etc.
This mechanism i continually endeavours to press C and has far as possible away
from each other i.e. when the vessel stands with C on the ground, it attempts
to raise the chamber A from the ground; as this action is to take place also when
the vessel is full, the force of the spring must be regulated accordingly.
The chamber-cover D is rotatably secured to the handle B at k by means of the
arm l, the other end of which m is formed on the other side of the pivot k as a stop
or catch or nose. If the cover is opened and the spring-mechanism i pressed
together by the weight of the person sitting on the chamber and A pressed
owards C, catches into a corresponding opening n or on a plate-spring o under a
orresponding projection, the lower end of o being attached to the bottom C.
On the person getting up later on from the chamber pot, i raises the vessel A
rom C, thereby causing the spring o to pull the nose m and thus throw the arm l
ound and close the cover D.

page_text: It is advisable to split the handle B, as shown in the drawing, above and below
into two arms p₁ på and g₁ q, in order to allow the arm of the cover and the
spring o to enter through the interstices thus formed; but also or at least its
continuation m and the spring o may be split or double, and be situated on both
sides of the handle; the lower part of the handle inay also be hollow, so
as to receive o etc.
It is also advisable to make the cover D of metal, wood or paste-board etc., in
order that it may not break, when it shuts down and in front a clasp r, as shown in
the drawing, may be provided, in order to prevent it from opening too easily and
furthermore a ring or borders round about at the point, where the cover and upper
chamber-rim meet in order to make any escape of air impossible.
The vessel and the different parts may be made of any kind of material and of
any shape and size.
F
The bottom C may be made of separate laths or plates or be replaced. by a ring,
a triangle etc.
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: .
Chamber pot with automatically closing cover, so arranged, that if any one sits
down on the vessel A, it goes down and presses together a spring-mechanism i
arranged between a and C, when the nose m on the cover arm catches into
a spring o and after the person gets up i expands again and raises the vessel, the
cover D being closed again by the action of o on m.
Dated this 18th day of June 1895.
