PROVISIONAL SPECIFICATION.
An Improved Hygienic Lid or Cover with Cleaning Device.
We, STEFAN SIEMANG and LEOPOLD GUTTMANN, both of No. 12 Mariahilfer Strasse,
in the City of Vienna, in the Empire of Austria, Engineers, do hereby declare the
nature of our invention, for "AN IMPROVED HYGIENIC LID OR COVER WITH CLEANING
DEVICE to be as follows:-
"
Our invention relates to an hygienic lid or cover with cleaning device which are
specially adapted for providing closets and chamber pots or other vessels containing
offensively smelling substances or fluids with an air-tight lid or cover, and at the
same time attain a cleaning of the upper surface or seat whereby a long felt want is
fulfilled in hygienic direction.
The closet openings are of varying form so that it is often found desirable to
arrange a new seat above the old one or the latter can be retained and the lid or
cover made to fit the same and the cleaning device made to suit the opening, which
can be provided with bevelled polished edges.
The conical edges of the tight fitting bevel edged lid or cover is clad with a layer
of india rubber and it will be evident that the heavier the lid the better will be the
closure effected by the same.
L
A tight closure can, however, be effected in other manner. If the opening in the
seat is not bevelled or provided with an india rubber layer, we arrange a lid or cover
made of two or more parts which are connected and guided by a centrally arranged
screw.
An india rubber ring or strip is clamped between the edges of these two parts and
when in normal condition protrudes somewhat beyond the edge of the cover. If.
however, the two parts of the lid or cover are brought nearer together by means of
the central screw, the india rubber ring will be compressed tightly against the edge
of the opening in the seat.
The cleaning device consists of one or more receptacles in which an absorbent
material such as sponge, for instance, is arranged. This receptacle is connected by a
suitable arm with the aforementioned bolt or screw.
By operating the receptacle or receptacles constituting the cleaning device, by
means of a handle one or more times, the surface of the seat is thoroughly cleaned
and in order to rapidly operate the lid or cover we provide a second handle which
can be turned down.
It is not absolutely necessary that the cleaning device be arranged to turn around a
single bolt as the same can be guided in rails along the periphery of the lid or cover,
but we consider the latter arrangement less advantageous than the former.
The air-tight closing lid or cover and the cleaning apparatus are so combined that
by operating the cleaning apparatus, the two or more parts of the cover will be
automatically tightened or loosened. The arm of the receptacle or cleaning device is
attached to a suitable nut to which the second handle is also fixed so that when the
latter is turned in conjunction with the nut, a compression or releasing of the india
rubber ring ensues.

An Improved Hygienic Lid or Cover with Cleaning Device.
We, STEFAN SIEMANG and LEOPOLD GUTTMANN both of No. 12 Mariahilfer Strasse,
in the City of Vienna, in the Empire of Austria, do hereby declare the nature of our
Invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :--
Our invention relates to an hygienic lid or cover with cleansing apparatus, which
are specially adapted for providing closets and chamber pots or other vessels
containing, offensively smelling substances or fluids with an air-tight lid or cover and
at the same time effect a cleansing of, the upper surface or seat whereby a long felt
want is fulfilled in hygienic direction.
The closet openings are of varying form so that it is often found desirable to
arrange a new seat above the old one or the latter can be retained and the lid or
cover made to fit the same and the cleaning device made to suit the opening, which
can be provided with bevelled polished edges.
Our improved air-tight lid or cover with cleansing device is represented in the
accompanying drawing, in which,
Figure 1 represents a seat B with bevolled edge, said edge being provided with a
thin layer of india rubber c, c.
Figure 2 is a sectional view of a modification of our hermetical cover.
Figure 3 is the top view of the lid represented in Figure 2.
Figuro 4 represents a like arrangement of lid or cover for chamber pots, it being
evident that the cleaning device is in this case not necessary.
The conical edges of the tight fitting bevel edged lid or cover is also clad with a
layer e, c¹ of india rubber, and it will be evident that the heavier the lid D the
better will be the closure effected by the same. A tight closure can, however, be
effected in other manner for instance, as represented in Figure 2.
In the opening in the seat B which, in this case, is not bevelled or provided with
an india rubber layer, we arrange a lid or cover D made of two or more parts, d¹, d²,
which are connected and guided by a centrally arranged screw i.
An india rubber ring or strip c is clamped between the edges of these two parts
and, when in normal condition, protrudes somewhat beyond the edge of the cover.
If, however, the two parts of the lid or cover d', d2 are brought nearer together by
means of the central screw i, the india rubber ring will be pressed tightly against
the edge of the opening in the seat.
As represented in Figure 2 the cover is provided with a hinge C which is, however,
not necessary when the edge of the opening is hevelled. The cleaning device consists
of one or more receptacles b, in which an absorbent material, such as a sponge for
instance, is arranged. This receptacle is connected with the aforementioned bolt or
screw by a suitable arm a.
By operating the receptacle or receptacles constituting the cleansing device b by
means of the handle one or more times, the surface of the seat is thoroughly
cleaned, and in order to readily operate the lid or cover D we provide a second
handle. It will be evident that it is not absolutely necessary that the cleaning
device be arranged to turn around a single bolt i as the same can be guided in rails
along the periphery of the lid or cover D or d², but we consider the latter arrange-
ment less advantageous than the former.
The air tight closing lid or cover D and the cleansing apparatus are so combined
that by operating said cleansing apparatus the aforesaid two or more parts d¹, d'
of the cover will bo automatically tightened or loosened.
The arm a of the receptacle or cleansing device is attached to a suitable nut m
to which the second handle is also fixed, so that when the latter is turned in
conjunction with the nut, a compression or releasing of the india rubber ensues.
The object of the spring f, Figure 2, is to facilitate the removal of the parts d', d²
of the lid from each other, but is not necessary when the india rubber is sufficient
for the purpose.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, we declare that
what we claim is :-
:―
1: In closets, chamber pots and other vessels, the use of lids or covers, consisting
of one or more parts such as d', d², and providing the edges thereof with india
rubber, substantially as and for the purpose set forth.
2: In closets, chamber pots and other vessels, the application of lids or covers
consisting of one or more parts, between the edges of which is placed a ring or
strip of elastic material e, adapted to protrude from said vessel when pressure is
exerted on the parts, substantially for the purpose of effecting an air-tight closure.
3-In closets and the like, the arrangement in combination with the cover or lid D
of a cleansing apparatus, consisting of the receptacle or vessel b, attached to a nut m
and a handle by means of the arm a, the whole being adapted to operate substantially
as and for the purpose set forth.
4-Tho combination of the hereinbefore described cleansing apparatus with closet
lids or covers in general and especially with lids such as D, substantially for the
purpose set forth.
5-The combination of an air-tight cover or lid such as D with the cleansing
apparatus b, by means of the bolt i, nut m and connecting arm a, substantially as
and for the purpose set forth in the foregoing specification, and shown in the
accompanying drawings.
