Improved Disinfecting Apparatus for Water Closets and the like.
I WILLIAM GEORGE ASHBURNER of Elliscales House Dalton in Furness in
the County of Lancaster Brewer do hereby declare the nature of this invention to
be as follows:-
The vessel forming the body of the apparatus which can be made of any desired
shape and capacity is intended to automatically distribute all kinds of disinfectants
in a liquid state, and to be used in conjunction with water closet and other flushing
tanks and cisterns. The vessel can be placed on the top of or adjacent to auy
ordinary cistern or tank so long as the bottom of the vessel is higher than the water
level in flushing tank when full. It is filled through a hole which is then closed and
made air tight. The contents are allowed to escape through a small hole, say of
an inch diameter made on side of vessel and near its bottom, and to flow over a level
canal having a flat bed say an inch wide and of an inch long, into a small well or
chamber extending say of an inch beyond; such canal and well being connected
to the vessel, and the bed of the canal being on a level with the lowest part of said
hole, and both the canal and the well being enclosed or walled in on both sides and
at the end to a height slightly exceeding the top of said hole. When the well
(which can be made of any required capacity but which for ordinary sized.
water closets need only be made to contain about a teaspoonful of a strong
disinfectant) is full the disinfectant ceases to flow until the well is emptied which
emptying is effected by a bent pipe forming a syphon, one end of which rests on
the bottom of the well and the other end extends to a point level with the centre
of the cutlet of the flushing cistern or tank. If it should be desired to impregnate
either a greater or a less quantity of the flushing water the pipe would be slightly
shortened or lengthened accordingly. The length of the pipe will vary according
to the position of the apparatus and the depth of the flushing cistern or tank, but
where the apparatus is intended for ordinary sized water closets the pipe should
not exceed of an inch internal diameter. The top end of the bent pipe or
syphon can if wished be kept in its place by an arm or support fixed to the side of
the vessel or other convenient place but ordinarily its own weight will suffice for
the purpose. The syphon pipe can be either brass or lead and the remainder of the
apparatus can be formed of tin earthenware or other material.

COMPLETE SPECIFICATION.
Improved Disinfecting Apparatus for Water Closets and the like..
I, WILLIAM GEORGE ASHBURNER, of Elliscales House, Dalton in Furness, in
the County of Lancaster, Brewer, 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 :-
The vessel forming the body of the apparatus which can be made of any
.desired shape and capacity is intended to automatically distribute all kinds of:

page_text: disinfectants in a liquid state and to be used in conjunction with water closet and
other flushing tanks and cisterns. It is filled through a hole which is then closed
and made air-tight. The contents are allowed to escape through a small hole
say of an inch diameter made on side of vessel and near its bottom, and to flow
over a level canal having a flat bed, say an inch wide and of an inch long into a
small well or chamber extending say of an inch beyond, such canal and well being
connected to the vessel, and the bed of the canal being on a level with the lowest
part of said hole, and both the canal and the well being enclosed or walled in on
both sides and at the end to a height exceeding the top of said hole. When the
well (which can be made of any required capacity but which for ordinary sized
water closets need only be made to contain about a teaspoonful of a strong
disinfectant) is full up to the top of the delivery hole the disinfectant ceases to flow
until the well is emptied, which emptying is effected by a bent pipe forming a
syphon, one end of which rests on the bottom of the well and the other end extends
to a point level with the outlet of the flushing cistern or tank. If it should be
desired to impregnate either a greater or a less quantity of the flushing water the
pipe should be slightly shortened or lengthened accordingly. The length of the
pipe will vary according to the position of the apparatus and the depth of
the flushing cistern or tank but where the apparatus is intended for ordinary sized
water closets the pipe should not exceed of an inch internal diameter. The top
end of the bent pipe or syphon can if wished be kept in its place by an arm or
support fixed to the side of the vessel or other convenient place but ordinarily its
own weight will suffice for the purpose. The syphon pipe can be of either brass,
lead or other material and the remainder of the apparatus can be formed of tin
earthenware or other material.
In the annexed drawings Figure 1 is a vertical central section, Figure 2 is a
plan and Figure 3 is a vertical section on the line 3, 3, Figure 2 of a disinfecting
apparatus made in accordance with this invention.
a is the reservoir for disinfectants having a hole b in its side, in this hole is fixed
a bush c onto which the apparatus is screwed.
The delivery hole d abuts on a level canal e at the end of which is a well f
The short leg g of a syphon A leading to the flushing cistern dips into the well f.
The action of the apparatus is as follows:-
When the well has been emptied the disinfectant flows out of the hole d until
the well is full and the disinfectant covers the hole. When the flushing cistern is
emptied a vacuum is produced in the syphon h and the disinfectant is delivered.
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 :-
1. A reservoir for holding disinfectants having projecting from it a horizontal
extension containing a well, the opening from the reservoir being level with a canal
leading to the well substantially as described.
2. A disinfecting apparatus for water closets and the like substantially as
described and shown in the drawings.
