PROVISIONAL SPECIFICATION.
Automatic Apparatus for Supplying Disinfectants to Water Closets
and the like.
We, FREDERICK HARVARD STACEY, Manufacturer, of Heeley Bridge
Foundry, and GEORGE JABEZ BEEDHAM, of Glen Road, Heeley, Engineer,
both in the City of Sheffield, do hereby declare the nature of our invention to be
as follows:-
-
This invention relates to an improved apparatus for supplying automatically a
disinfectant, such as.Condy's fluid, to the flush pipe of water-closets and the like.
It consists of a vessel interposed in any suitable position upon the flush-pipe and
made of any suitable configuration to suit the position in which it may be placed,
such as the wall or the corner of a room. It is connected at the top and under-side
with the separated ends of the flushing pipe and these communicate directly one
with the other through a central tubular water-way which passes through the
closed interior of the vessel. This water-way is preferably made conical or
tapering towards the centre, at which point it is expanded so as to form an
annular chamber. From this annular chamber and communicating with it a small
pipe is taken upwards to the top of the interior of the vessel or thereabouts, where
it is bent over and descends nearly to the floor of the chamber, where it terminates
in a valve chamber, preferably of a spherical form. A small hole is made through
the bottom of the valve chamber to admit the fluid disinfectant which is poured
into the vessel through any convenient opening in its cover plate.
Within the valve chamber is placed a small ball which acts as a valve, aud closes
either the small entrance hole before mentioned or the entrance to the pipe as the
case may be. When the vessel is supplied with the liquid disinfectant, the syphon-
shaped pipe becomes charged with the liquid to a certain height. On the flush
taking place the stream of water, rushing through the centre of the annular
chamber carries the air with it and creates a partial vacuum, and draws the
disinfecting fluid out of the pipe, causing the valve to lift and stopping any further
supply.
When the flush has past, the valve drops and closes the entrance aperture and
thus prevents syphonage being set up. The tubular water way is preferably made
as a separate part but if desired it may be cast in one piece with the body of the
vossel.

We, FREDERICK HARVARD STACEY, Manufacturer, of Heeley Bridge
Foundry, and GEORGE JABEZ BEEDHAM of Glen Road, Heeley, Engineer,
both in the. City of Sheffield, do hereby declare the nature of this invention
and in what manner the same has to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to an improved apparatus for supplying automatically any
disinfectant in liquid form such as Condy's fluid, to the flush pipe of water closets,
urinals, and the like.
The invention as applied in one form to the flush pipe of a water closet for
example is illustrated in the annexed sheet of drawings in which:
Fig. 1, is a sectional elevation of our improved apparatus.
Fig. 2, is a plan of the disinfectant box with the cover removed.
It consists of a vessel A of any suitable outer configuration to suit the position
in which it is most convenient to fix it, either for example against a flat wall, or in
an angle, the one illustrated being to fit against a flat wall.
This vessel which is to contain the supply of disinfectant is interposed in any
suitable position upon the flushing pipe between the flushing cistern and the closet
or urinal.
It consists of the reservoir or chamber B, to contain the liquid disinfectant, and
a separate removable waterway C, of tubular form, which is connected with the
divided flushing pipe at both ends, so as to give a direct and continuous flow of
water between the cistern and the closet through the disinfectant vessel.
Near the centre of the waterway C, is an annular chamber D, and opening into
this aunular chamber is a communication E, which extends to the bottom or
thereabouts of the chamber B.
A valve chamber and valve may be placed in any suitable position or part of
this tubular communication or pipe E, but we find that the position shown in the
drawing is most convenient. The valve chamber F. is preferably spherical, and
contains a ball valve G, but a clack valve or any equivalent valve may be
substituted.
A small opening H, for the passage of air to break syphonic action may be made
in any part of the valve chamber, and 1, is a short length of metal tube forming
the termination of the communication E.
For convenience of manufacture these parts last described may be made
separately and be attached to the waterway C, by a screwthread J, or by other
means.
The vessel is closed by the cover plate K, and the disinfectant is supplied
through an opening at L, but this forms no part of the invention.
On the flush taking place, the stream of water rushing through the waterway C,
carries the air in the annular chamber D, and pipe E, with it thus producing a
partial vacuum of sufficient power to draw up some of the liquid disinfectant from
the reservoir into the pipe E, before the ball G, is also carried forward and closes
the aperture as indicated.
When the flush of water has passed, the suction in the pipe E, ceases, and the
ball valve drops to its normal position over the mouth of the pipe 1.
Syphonic action would under some circumstances be set up, and to avoid this a
small hole H, is provided, which admits sufficient air for the purpose, aided by
weight of the ball over the orifice of the pipe I.

page_text: The vessel A, may be made of cast iron, or of other material such as glass to
enable the quantity of disinfectant to be readily seen, or of a combination of
materials, and the cover plate K, instead of being screwed down, may be made to
slide into position so as to be easily removed for any purpose.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :—
An apparatus for supplying a fluid disinfectant automatically to water closets
and the like, constructed and operating as hereinbefore described, and substantially
as shown in the annexed drawings.
