Improvements in Apparatus used for the Disinfection of Water
Closets and for similar purposes.
I, WILLIAM HENRY WITHINGTON of 436 Moss Lane East Moss Side
Manchester in the County of Lancaster, Gentleman 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 :—
My invention has for its object an improvement in the apparatus for which I
have made application for Letters Patent the said application being numbered 2945
and dated the 18th day of February 1891. In carrying my said invention into
effect I modify the construction of the vessel containing the disinfecting or
deoderising material as described and illustrated in my before mentioned applica-
tion so as to simplify its construction and improve the construction of the perforated
bottom. And in order that my said invention may be easily understood and more
readily carried into effect I have hereunto appended a sheet of drawings wherein
Fig. 1 is a vertical elevation Fig. 2 a vertical section Fig. 3 a plan view and Fig. 4
an internal view of the vessel with the lid removed.
I construct of some suitable material and of a convenient shape a vessel C of
convenient size which I divide into two compartments D and E by a diaphragm or
division plate F. The diaphragm is fixed in a suitable position in the vessel C
and the solution of the disinfectant produced as described in my hereinbefore
mentioned application for Letters Patent can be collected in the lower compart-
ment E and be discharged therefrom by the outlet pipe G. The inlet pipe Band
the outlet pipe G are fixed and connected to the flushing pipe or closet pan and to
the vessel substantially in similar positions and in the same manner as fully
described in my aforesaid application and I do not therefore particularly describe
this portion of the apparatus.
I perforate the diaphragm F in some convenient manner so that the water
passing through the disinfectant or deoderant can readily pass into the lower
compartment E. Although the perforations H can be made by moulding_drilling
or punching so as to leave the surfaces of the diaphragm level I prefer to form the
perforations in such a way that surrounding each hole there is a lip by means of
which the orifice is raised above one of the surfaces of the diaphragm. This lip
may be formed by pressing, moulding, casting, or punching according to the
material employed as will be easily understood and readily carried out by any
person conversant with the materials used. My object in forming this lip is to
ensure that after the water discharged as hereinbefore described has passed through
the disinfecting material it shall not entirely drain into the lower compartment but
that a small portion shall be always retained in contact with the disinfecting
material. The water retained in the manner described prevents the perforations H
becoming choked by the disinfectant in the upper compartment D and becomes
when an intermittent flush is employed strongly charged with the disinfectant or
deoderant. When the flushing operation takes place the water can readily pass
without obstruction into the lower compartment G and the solution produced as
described is more readily drained off at each flush.
In order to prevent the water overflowing the sides of the vessel I fix an over-
flow pipe J by which the excess of water is delivered into the lower compartment E
and discharged by the outlet pipe.
Having now particularly described and ascertained the nature of my said inven-
tion and the manner in which the same is to be performed I declare that what I
claim is.

containing a supply of a suitable disinfectant or deoderant which is dissolved and
discharged substantially as herein described and illustrated.
2nd. The combination construction and arrangement for the purposes herein set
out of a vessel with a diaphragm formed with perforations in such a manner that 5
the orifice of the perforations is raised above the surface of the diaphragm sub-
stantially as herein described and illustrated.
Dated this 28th day of April 1891.
