COMPLETE SPECIFICATION.
An Improved Means for Disinfecting or Deodorizing Water-closets
and the like.
I, JULIUS SOMMER, of 52, Johannesstrasse, Stuttgart, in the Empire of Germany,
Chemical Manufacturer, 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 :-
Particular attention has been devoted in recent times to the disinfection and
deodorization of water closets, and the like. The scattering of disinfecting powder
down the pan which is the custom usually adopted, or the pouring of liquid
disinfectant substances into the same has only a temporary action which requires
when regularly repeated a considerable consumption of time and a large quantity
of disinfecting material, and thus becomes somewhat expensive. The placing of
disinfecting or deodorizing substances in closets has of course the action of
disinfecting or deodorizing the air in these rooms but is usually connected with a
sharp unpleasant smell, whilst the most essential source of smell, namely the pan of
the closet, is not disinfected or deodorized.
My improved arrangement which consists in applying the disinfecting or
deodorizing substance beneath the cover or lid of the closet entirely removes all
these drawbacks.
A closet lid or cover provided with this improved arrangement is shown in the
accompanying drawings, Figure 1 being a cross section, Figure 2 a view from
beneath and Figure 3 another cross section in which the method of attaching the
disinfecting material somewhat differs from that shown in Figure 1.
A suitable disinfecting or deodorizing substance C is inserted in a recess a¹ of the
lid or cover A and is attached to a sheet metal plate B by single strips or bands &¹
being bent over it, said disc engaging over the edge a of the closet lid and being
held to the said lid A. by means of screws, pins & or the like.
The sheet metal disc B holding the disinfectant C has a number of openings b
through which the air saturated with dissolved disinfectant or deodorizing
substances which is somewhat heavier than ordinary air can descend and pass into
the closet waste pipe. In place of special holes b in the bottom of the disinfecting
substance holder B, other suitable perforations, such for instance as the name and
address of firms or the like, as shown as an example in the drawings, may be
formed which fulfil the same object.
Figure 3 shows a modification of the sheet metal disc B₁ for receiving the
disinfecting substance B, which in this case is not let into the privy or closet lid A¹
but directly attached by its edge b2 beneath the same. Such arrangement is
especially suitable when the ordinary closet covers at present in use are to be
provided with this improved arrangement.
It is evident that the attachment of the disinfecting or deodorizing substance to
the closet lids may take place in several other suitable ways. The essential point
however is the connection of disinfecting material with the closet lid itself.
For water and earth closets for instance the lid or cover may be provided with a
pleasant smelling perfume instead of a disinfecting substance.

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 I
claim is
Providing the lids of water closets and the like with a suitable disinfecting or
deodorizing substance or perfume or the like attached underneath said lids,
substantially as herein before set forth.
