Improvements in Apparatus and Materials for Automatically
Disinfecting Water-closets, Urinals, and other similar Places.
We WILLIAM HEYWOOD of 66 Fountain Street Manchester Drysalter and GEORGE
HEYWOOD of Little Green, Middleton Lancaster Dyer do hereby declare the nature
of our said invention to be as follows:-
-
As applied to disinfecting water-closets we employ a suitable casing to contain
Permanganate of Potash in crystal form and which casing opens into a perforated
pipe leading into the basin of the water closet. This casing which is also provided
with a branch pipe for connection with the flushing pipe of the water supply is
designed to intercept a portion of the flushing water on its way to the closet and so
to impregnate the same with the Permanganate of Potash. In this manner we are
enabled to effectually disinfect the water closet and its soil pipe.
This casing and perforated passage may be formed in the earthenware basin itself
or may be applied thereto as a separate apparatus.
It will be apparent that our improvements are equally applicable to disinfecting
urinals and other similar places.
Dated this 25th day of October 1888.

We WILLIAM HEYWOOD of 66 Fountain Street, Manchester, Drysalter and GEOR
HEYWOOD, of Little Green, Middleton, Dyer do hereby declare the nature of o
said invention and in what manner the same is to be performed to be particular
described and ascertained in and by the following statement:-
As applied to Disinfecting Water Closets we employ a suitable casing or chambe
to contain Permanganate of Potash or any other suitable disinfectant and whic
casing opens into or forms a perforated pipe or passage leading into the basin of th
water closet. This casing is designed to intercept a portion of the flushing water o
its way to the closet and so to impregnate the same with the disinfectant employed
In this manner we are enabled to effectually disinfect the water closet and its soi
pipe.
This casing or perforated passage may be formed in one piece with the earthen
ware or other water closet basin itself or may be applied thereto as a separate
apparatus.
It will be apparent that our improvements are equally applicable to disinfecting
urinals and other similar places.
And in order that this our said invention may be the more readily understood and
carried into practical effect we have hereunto annexed a drawing of a water closet
basin having our improvements applied.
Fig. 1. is a side sectional view and Fig. 2. a plan view of our improved water closet
disinfecting apparatus shewing how the same may be constructed all in one piece.
Fig. 3. is a transverse section of Fig. 1. on the line a-b.

nd by mixing with the disinfecting liquid contained in the channel d so causes the
me to overflow through the perforations e' into the basin.

page_text: In this manner we secure the perfect disinfecting of the basin and soil pipe.
It will be observed that our improved disinfecting reservoir is not an enclosed vessel
but is open to the atmosphere at the top and thus not only serves to disinfect the
water closet basin but the surrounding atmosphere and at the same time facilitates
the introduction of fresh disinfecting material when required.
Although only illustrated as applied to a flush out closet it will be apparent that
our improvements are equally applicable to pan or valve closets and to urinals and
other similar places and it will be equally obvious that the disinfecting reservoir may
be constructed say of sheet copper or other suitable metal and as a distinct and
separate part from the basin or may be arranged to be connected on the length of the
service pipe or attached to or form part of the flushing cistern.
•
As applied to existing water closets or when affixed at a higher level than the water
closet basin instead of employing the perforation e' we prefer to employ an overflow
pipe to convey the disinfecting solution from the reservoir and arranged to discharge
itself over the top edge of the basin.
We wish it to be distinctly understood that we make no claim to a separate and
enclosed vessel containing disinfectant and connected to the flushing pipe of a water
closet so as to divert a portion of the flushing water through such apparatus into
the basin of the water closet as we are well aware that such an arrangement has
hitherto been used.
Having thus particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what we
claim is
1st. The improved construction and arrangement of disinfecting apparatus applied
to water closets, urinals and other similar places substantially as hereinbefore
described.
2nd. In disinfecting water closets the employment of a chamber or casing con-
taining disinfecting solution caused to overflow at each action of the flushing valve
substantially as and for the purposes hereinbefore described.
3rd. The improved combination of water closet basin and disinfecting reservoir
substantially as and for the purposes herein before described and illustrated on the
accompanying drawing.
