An Improved Apparatus for Disinfecting Water Closets and for
similar purposes.
I WILLIAM HENRY WITHINGTON of 436 Moss Lane East Moss Side Man-
chester in the County of Lancaster, Gentleman do hereby declare the nature of
this invention to be as follows:-
My invention relates to that form of apparatus which is used to supply a certain
quantity of any suitable disinfectant every time water closets, urinals or drains are
flushed. My invention has for its object the provision of means by which a small
quantity of the disinfecting substance is dissolved each time the flushing operation
One of the
takes place by means of an intercepted portion of the flushing water.
Ichief objects of my said invention is to enable the before mentioned solution of a
portion of the disinfectant to take place and after this has been accomplished to
take the water used to dissolve it out of contact with the disinfectant thus avoiding
waste and ensuring that no more than the requisite amount of disinfectant is dis-
solved at each flush.
In carrying my said invention into effect I construct a suitably shaped vessel of
earthenware, metal or other suitable material which can be affixed in any con-
venient position. Enclosed within the before named outer vessel is an inner vessel
or its equivalent which is sustained in such a manner that a space is left between
its outer surface and the inner surface of the outer vessel. I place within the
inner vessel the disinfecting material and I construct it with perforations so that
the water passing into it can casily drain through or fall by gravitation out of the
inner vessel. The water passing through the disinfectant dissolves a certain portion
of it and falls into the space left between the bottom of the inner vessel and the
bottom of the outer vessel. To admit the water to the disinfectant I connect to the
flushing pipe another pipe, hereinafter called the inlet pipe, one end of which
projects a limited distance within the flushing pipe and the cuter end of which
terminates within the outer vessel at such a point that it will discharge the water
intercepted by it into the inner vessel. At a convenient point above the bottom of
the outer vessel I connect a second pipe hereinafter called the outlet pipe which I
may also pass into the flushing pipe at some convenient point. I give the outlet
pipe such an incliuation and connect it to the outer vessel at such a point that it
can drain off the whole or part of the solution collected at the bottom of the outer
vessel and discharge it at some convenient point after the operation of flushing is
accomplished. I may so proportion the inlet and outlet pipes that the velocity of
the passage of the water through the vessel will be regulated.

'An Improved Apparatus for Disinfecting Water Closets and for
similar purposes.
I WILLIAM HENRY WITHINGTON of 436 Moss Lane East Moss Side Man-
chester 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 the provision of means by which a small quantity

page_text: of the disinfecting substance employed is dissolved each time the flushing operation
takes place by means of an intercepted portion of the flushing water. One of the
chief objects of my said invention is to enable the before mentioned solution of a
portion of the disinfectant to take place and after this has been accomplished to
permit the water used to dissolve it to pass out of contact with the disinfectant
thus avoiding waste and ensuring that no more than a certain amount of the dis-
infectant is dissolved at each flush.
And in order that my said invention shall be the more easily understood and the
more readily carried into effect I have hereunto appended a sheet of drawings
wherein Fig. 1 is a vertical elevation Fig. 2 is a sectional view Fig. 3 is a plan
view of the top and Fig. 4 is a transverse sectional view of the apparatus.
I construct of earthenware metal or other suitable material by moulding
stamping or in any convenient and well known method a vessel or case C of
cylindrical rectangular or other suitable shape. I close up the bottom of the vessel
and I may fit a lid K to it so that it can also be closed at the top. The aforesaid
vessel C herein called the outer vessel encloses another vessel D of smaller dimen-
sions herein called the inner vessel. The inner vessel D may be constructed of
similar materials, in a similar manner and of similar shape as the outer vessel but I
may vary it in each of these particulars. The inner vessel D is formed with a
perforated bottom E and sustained by feet I or their equivalents so that a space F
is left between the bottom of the outer vessel C and the bottom E of the inner
vessel D. The outer vessel with its enclosed inner vessel can be readily fixed in
any convenient position which may be desired to suit different conditions."
I fix into the flushing pipe A by screwing or some other convenient method a
pipe B of suitable bore herein called the inlet pipe and I project it into the flushing
pipe for a certain distance so that it shall intercept a portion of the water flowing
within the flushing pipe A. The other end of the inlet pipe B terminates at a
point immediately above the inner vessel so that when the water is intercepted it is
discharged into the inner vessel D. 1 also fix in some convenient manner into the
flushing pipe A a second pipe G of suitable bore herein called the outlet pipe one
end of the said pipe G being attached in some convenient manner to the outer
vessel C at a convenient point either in the bottom or the side of C as shown in
Fig. 2.
A. hole may be formed in the outer vessel C and a nipple may be also
formed to which the pipe G can be attached. The other end of the outlet pipe G
is passed within the flushing pipe A and is given a downward bend or inclination
within the same so as to cause any liquid flowing from the outlet pipe to pass into
the flushing pipe in the direction of the flow of the flushing water as indicated by
Instead of passing the pipe C into the flushing pipe A I may cause it
to discharge its contents independently into the water closet pan urinal or other
convenient place as desired.
the arrow.
The operation of the hereinbefore described apparatus is as follows. I place
within the inner vessel D a sufficient quantity of the disinfecting material used. I
may use any disinfectant or deoderant suitable for the purpose and I do not specify
or claim any particular compound as a part of my invention. When the inner
vessel D is charged the water intercepted in the manner hereinbefore described
whenever water is flowing in the flushing pipe falls upon the disinfecting material
within the inner vessel and passes through the same at a velocity depending
upon the density of the material employed. In its passage the water dissolves a
portion of the disinfecting material and the solution so obtained is collected in the
space between the bottom of the inner and the bottom of the outer vessel shown
at F in Fig. 2, from which it is conveyed by the outlet pipe G and discharged in
the manner herein before described. By proportioning the bore of the inlet and
outlet pipes suitably the quantity of water delivered by the inlet pipe and the
quantity of the solution discharged by the outlet pipe in a given time can be
regulated so that the flushing operation can be completed before the discharge of
the whole of the solution produced as herein before described into the flushing pipe,
water closet pan or other similar place.

page_text: It will be understood that the word disinfectant includes substances used as
deoderants which are often termed disinfectants.
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
In combination with water closets urinals or similar articles a double vessel the
inner vessel enclosed within the outer vessel and the inner vessel constructed with
a perforated bottom and arranged to contain a suitable disinfectant which can be
dissolved by the discharge on to it of a portion of the water flowing in the flushing
pipe the solution obtained in the manner described being subsequently discharged
at some convenient point substantially as herein described and illustrated.
