COMPLETE SPECIFICATION.
Improved Disinfecting Apparatus for Water Closets and the like.
WALTER PRESTON Manufacturing Chemist 12 Sydenham Street Holbeck
Leeds Yorkshire 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 improved disinfecting apparatus "S" is made of tin or any metal or
earthenware, and is made from two inches diameter or square oblong or larger
as the tank requires. It is made from four to eight inches in height.
The lid "D" is screwed or soldered on. The lid of the improved disinfector is
perforated with small holes "A" of an inch diameter or larger. These
perforations "A" allow the water in the tank to enter and dissolve the disinfectant,
which shall be perfectly soluble in water. In the centre of the lid is a small
funnel "B" screwed or soldered into the lid. The funnel has about three eights
of an inch opening into the lid "D," for one inch in height it is perfectly straight.
It then widens out to about one and half inches in diameter and rises another
inch, thereby forming a small funnel "C" on the top of the lid "D" about two
inches in all above the lid.
The water as it ascends in the tank when filling enters the perforations "A" in
the improved disinfector and acts upon the disinfectant and dissolves a small
quantity of it.
The water which has entered the perforations "A" in the lid "D" rises in the
funnel "B" and carries with it the dissolved disinfectant. The water continues to
rise in the tank and covers the improved disinfecting apparatus.
When
The water at this point ceases to act further upon the disinfectant. The dis-
infectant being heavier than water consequently will not rise out of the improved
disinfecting apparatus without any pressure being put upon it Also because the
area of the perforations in the lid "D" is less than the area of the top of the
funnel "C" and with the improved disinfecting apparatus been under water.
There is equal pressure upon the lid "D" as there is on the top of the funnel "C"
consequently there is no action upon the disinfectant, when not required.
the closet is flushed, and the water in the tank has got below the top of the
funnel "C" the disinfectant in the funnel begins to discharge through the
perforations "A" in the lid "D" and continues to discharge until the water in
the tank, has got below the lid "D." The disinfectant mixes with that portion of
the water, which is the last out of the tank, thereby automatically disinfecting the
water closet or the like every flush by leaving the disinfectant in the trap of the
closet. The column of disinfectant in the funnel as per drawing, is sufficiently
large enough for a tank which discharges six gallons of water each flush. The
funnel has to be made larger for tanks discharging larger quantities of water.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim
1. That by the aid of the funnel "C" upon the lid "D" a column of disfectant
is automatically discharged out of the improved disinfecting apparatus by the
perforations "A" in the lid "D" every time the tank is emptied to flush the water
closet and the like

page_text: 2. That it is simple in construction and without any valve or anything that can
possibly get out of order.
3. That it can be used for all known disinfectants which are soluble in water.
