PROVISIONAL SPECIFICATION.
An Improved Device for Charging Liquid with Disinfectant, chiefly
intended for use in Flushing Cisterns.
I JOSEPH EDWARD LILLEY of Wealdstone, Harrow, Middlesex Gentleman
do hereby declare the nature of this invention to be as follows:-
A receptacle made of metal, earthenware, china or any other material capable of
holding liquid, perforated or punctured at the side or sides, the portion of the
receptacle below such line of puncture or perforation can then be filled with per-
manganate of potash or other disinfectant and placed in a cistern or vessel. Each
time such vessel is filled the liquid filling same enters the puncture or perforation of
the receptacle and mixes with the disinfectant therein, but on the liquid escaping from
the cistern or vessel, only such portion of the disinfectant as has been carried to
the upper portion of the receptacle by the entrance of the liquid can escape,
leaving the remainder for future use in the same manner. The apparatus is more
particularly suitable for use in flushing cisterns.
COMPLETE SPECIFICATION.
An Improved Device for Charging Liquid with Disinfectant, chiefly
intended for use in Flushing Cisterns.
I, JOSEPH EDWARD LILLEY, of The Chestnuts, Wealdstone, Harrow, in the
County of Middlesex, 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 relates to an improved disinfecting apparatus and has for its object
to provide means whereby a quantity of disinfectant is automatically removed from
a store of the same and distributed throughout a vessel or receptacle every time
such vessel is emptied and filled with liquid; my improved apparatus is thus
especially suitable for use in flushing cisterns.
According to my invention I provide a receptacle made of metal, earthenware,
china or other material capable of holding liquid, and that will not be attacked by
the disinfectant used, and having its side or sides perforated at a suitable height
from the bottom of the same. The receptacle being filled up to the level of the
perforations with a suitable disinfectant, permanganate of potash for example, is
placed in the vessel or cistern which it is required to supply with disinfectant.
Each time such vessel or cistern is filled with liquid a portion of said liquid enters
the disinfecting receptacle through the perforated side or sides thereof and mixes
with the disinfectant therein. When the liquid is discharged from the vessel or
cistern, that portion of the disinfectant which has been carried to the upper part of
the disinfecting receptacle by the entrance of the liquid therein escapes with the
bulk of the liquid, while the remainder is left in the receptacle for future use.
The accompanying drawing is a perspective view showing a tank or cistern filled
with liquid and having a receptacle for holding disinfectant constructed according
to my invention placed therein.
Part of the side of the tank is broken away in order to shew the receptacle clearly.
The receptacle A for the disinfectant has one side perforated with holes A' A¹
and is fixed in such a position in the tank or cistern B that the said perforations
are at a suitable distance below the normal level of the liquid in the said tank.
FO

page_text: When the tank is filled with liquid, a portion thereof enters the receptacle A and
takes up more or less of the disinfectant which when the tank is emptied flows out
of the receptacle and mixes with the bulk of the liquid, thus disinfecting the whole.
It is evident that when the tank or cistern B is emptied the disinfecting receptacle A
will still remain filled up to the level of the holes A' A' so that only a portion of
the disinfectant will be removed each time the cistern is emptied of its contents.
The amount of disinfectant removed at each operation will to a certain extent
depend on the distance of the perforations A¹ below the normal level of the liquid
in the tank or cistern B. I sometimes provide hooks as shewn at A2 A' in the
drawing by which to hang the receptacle from the side of the cistern or from any
other suitable support.
The receptacle can obviously be made of any convenient shape and be provided
with any suitable number of perforations. I may also provide a lid or suitable
opening at the top or side of the receptacle for the purpose of charging the same
with disinfectant.
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. In an apparatus for charging liquid with disinfectant, a receptacle for
containing the disinfectant so constructed and arranged in a tank or cistern that a
portion of the liquid to be disinfected will enter said receptacle and mix with the
disinfectant therein, and will flow out when the tank or cistern containing the liquid
is emptied thus removing a portion of the disinfectant and leaving the remainder
for future use, substantially as described.
2. The improved apparatus for charging liquid with disinfectant constructed
substantially as described, and operating as specified.
