PROVISIONAL SPECIFICATION.
An Improved Method of Using Disinfectants in Porous Cylinders.
I THOMAS GRIMSTONE of No. 10 Wellington Street, Camden Town London,
Disinfectant Manufacturer do hereby declare the nature of this invention to be as
follows:-
My invention consists of a new method of using disinfectants in the flushing
cistern or waste preventor.
My plan is to employ porous cylinders, which will contain all kinds of pungent
disinfectants, to be amalgamated with a basis to prevent a volatile effusion, and to
be sealed hermetically to prevent any influx of water.
Dated this 3rd day of February 1896.

An Improved Method of Using Disinfectants in Porous Cylinders.
I THOMAS GRIMSTONE of 10 Wellington Street, Camden Town London N.W.
Disinfectant Manufacturer, 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 method of combining soluble pungent
disinfectants with silica as a basis to form a paste, and the packing of the same in
suitable hermetically sealed porous vessels to be employed for disinfecting and
deodorizing purposes in the flushing cisterns and water waste preventers of w.c's,
lavatories and the like, stable and other pails and similar vessels, my said invention
having for its object to effect such disinfecting or deodorizing automatically with
greater precision and with less attention and expense than by the methods and
means hitherto employed.
In carrying my invention into effect I employ any suitable pungent disinfectant
or deodorizer, which may be permanganate of potash crystals alone, but I prefer
to employ kresyline (or soluble creosote) eucalyptol, terpinol, or carbolic acid in
liquid form, or any desired combination of these or their equivalents, to which I
add as a basis silica to prevent volatile effusion, preferably in the proportions of
four to one, or thereabouts, so as to form a thick paste, and the said crystals or the
said paste I then place in a preferably cylindrical porous pot, (made of any
suitable material and of any desired containing capacity) until I fill or nearly fill
the same, which I then cover with a tight fitting cork or bung having in its centre
an upstanding book or eye, the whole being then hermetically sealed by filling the
remainder of the pot above the said bung or cork with Portland or other
non-porous cement to the level of the top of the same, with the said hook or eye
extending through the said cement.

page_text: For use in flushing cisterns or water waste preventers, the said pot would be
stood preferably upright in any convenient position, so as to be covered or partly
covered with water when the cistern is filled, the said hook, loop or eye being for
the attachment of a wire or the like for maintaining the perpendicularity of the
said pot. The action would be as follows.
By reason of the said pot being hermetically sealed, only a certain quantity of
water could (by the action of endosmosis) enter through the pores of the pot,
thereby dissolving only so much of its contents as would lie nearest to the inner
surface of the same, when (by the action of exosmosis) the said dissolved portion
would percolate through the said cylinder or pot until the water in the cistern
becomes saturated therewith, when such dissolution would cease until the contents
of the cistern was removed and refilled in the usual way, and the same limited
dissolution of the contents of the cylinder would be repeated and continued until
such contents was exhausted, which may be indefinitely prolonged according to the
size of the cylinder.
I may arrange that a cylinder so charged may lie down upon, and be fixed by
suitable clips to, the bottom of such a pail or bucket as may be used for washing
down the drains and other parts of stables, cow-houses, urinals, lavatories and like
places for sanitary purposes, such pail or bucket by the simple operation of filling
and emptying operating upon the contents of the cylinder or porous pot in the
same manner as the water in the cistern previously described.
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.
1st. For disinfecting and deodorizing purposes the combination of a hermetically
sealed porous cylindrical or other vessel containing any suitable disinfectant or
deodorant, and the employment of same in flushing cisterns or water waste
preventers in w.c's, lavatories or the like, and or fixed in the bottoms of pails or
buckets substantially as and for the purposes herein set forth.
2nd. As a disinfectant or deodorant easily soluble in water, the combination of
kresy line, eucalyptol, terpinol or carbolic acid, or any desired combination of these
with silica as a basis, in or about the proportions stated, substantially as herein
described.
3rd. For disinfecting or deodorizing purposes, the combination of a porous
cylinder or pot containing disinfecting or deodorizing crystals, or a pasty
compound composed of kresyline, eucalytol, turpinol, or carbolic acid or any
desired combination of these and silica in or about the proportions stated, the
whole being hermetically sealed by Portland or other non-porous cement,
substantially as and for the purposes herein set forth.
