Improvements in Disinfectants and Antiseptics.
ALFRED PLANNER, 1, Ledbury Villas, Stuart Road, The Newlands, Peckham
Rye, S.E., Disinfectant Manufacturer, do hereby declare the nature of this
invention to be as follows:-
The object of my invention is to render solid-disinfectants or antiseptics such
as permanganate of potash more slowly soluble in water, that it may be entirely
immersed in the water of flushing tanks or other vessels, and to form it into a
tablet or other shape which I may suspend by means of one or more wires or
other suitable means. In carrying out my invention I prefer to take per-
manganate of potash or other suitable disinfectants or antiseptics and to mix it
with camphor and napthalene (or either of these) or other suitable substance or
substances which will have the effect of both hindering the solubility of the dis-
infectant and enabling it to be formed into a solid mass.

I, ALFRED PLANNER, of 1, Ledbury Villas, Stuart Road, The Newlands, Peck-
ham Rye, London, S.E., Disinfectant Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
-
My invention relates to improvements in the manufacture of solid antiseptic
or disinfectant compounds, formed into balls, blocks, or tablets, and adapted to
be suspended above, and immersed in the water contained in the flushing cisterns
of water-closets, lavatories and like places as a means for disinfecting such water
when used, the object of my said invention being to render whatever form of
solid disinfectant or antiseptic, I may employ in the manufacture of the said
compound, slowly soluble in water, in order that each flush of water may contain
only a given or suitable per-centage of same, sufficient for the purposes of disin-
fecting such flush only.
My invention consists in intimately mixing the disinfectant or disinfectants or
antiseptic or antiseptics employed with any suitable hydrocarbon or hydrocarbons
or their derivatives, or oxygenized hydrocarbon, or hydrocarbonic compound, that
is or are solid and fusible, and insoluble in water or nearly so, in order that only
such of the crystals or particles of the disinfectants or antiseptics employed, as
can be reached by the water may be dissolved to disinfect each flush, so that the

page_text: holes or apertures left in the solid mass by the dissolving of the outermost
crystals or particles at one flush, may serve as conduits for the admission of
water to the next crystals or particles in order to dissolve the next outermost of
these for disinfecting the next flush, and so on.
I do not confine myself to the use of any particular form of solid disinfectant
or antiseptic, but may employ such as borax, boracic acid, salicylic acid or per-
manganate of potash or any desired combination of such or other like substances,
but for preference I use permanganate of potash crystals or powder only, as I
find in practice that this substance answers my purpose best.
Of the large variety of solid fusible carbon substances or compounds insoluble
in water or nearly so, that readily lend themselves for the purposes of my
invention, I submit the following as examples, any of which, or any desired com-
bination of two or more whereof I reserve the right to employ in the manner
hereinafter set forth.
Naphthaline, acenaphthene, diphenyl, fluorene, anthracene-dyhydride, anthra-
cene-hexahydride, phenanthrene, pseudophenanthrene, synanthrene, fluoranthrene,
pyrene, chrysene, chrysogen, retene, picene, benzerythrene, or camphor or other
oxygenized hydro-carbon, or any derivative, substitution or additive compound
thereof.
In carrying my invention into effect I do not confine myself to any specific
proportions of the ingredients employed, as these may vary according to the
strength desired, or other considerations, but as an example I will assume that
camphor and napthalene are the carbon substances employed, of each of which
I take, as the most convenient proportions 1 parts or thereabouts, by weight,
and for preference I first melt the napthalene by heat and then add the campthor
thereto, and this mass when cold I pulverize, and mix therewith 12 parts or
thereabouts by weight of permanganate of postash in crystals or powder, the
whole being then melted together by heat, without the addition of moisture in
any form, except such matter as may or may not be desirable for imparting a
color or tint to the whole, the mass while plastic being then moulded or otherwise
formed into balls, blocks, tablets, plano or plano-convex discs, or other suitable
shapes, or I may if found more convenient add the permanganate of potash, while
the napthalene and camphor are in a melted state, instead of first cooling, powder-
ing, and remelting these as described, but whichever process I may adopt, to
each of the said balls, discs, or the like, while plastic or otherwise, I connect a
wire or wires, or any suitable equivalent therefor, by means of which the same
may be suspended above, and be always immersed in the water contained in the
flushing tank of the w.c., lavatory, or other place of use, the said ball, disc or the
like then automatically serving for disinfecting each flush in the manner herein-
before described, until the whole of the permanganate is used up.
Although prefer to melt the carbon substance by heat without the addition
of moisture as stated, I do not confine myself to this method, but may render
the same into a melted or plastic condition by the use of any solvent of the carbon
substance employed or by compression.
Having now particularly described, and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1st. The improvements in disinfectant or antiseptic balls, blocks, tablets, discs
or the like for suspending above and immersing in the water of flushing tanks
and the like, substantially in the manner herein set forth and for the purposes
stated.
2nd. The manufacture of antiseptic balls, blocks, tablets, discs or the like by the
combination of any suitable solid, fusible, hydrocarbon or carbon compound other
than wax, and insoluble in water or nearly so, and permanganate of potash or
other suitable solid soluble disinfectant or antiseptic substance, in the proportions
stated or thereabouts, and the employment of same suspended above and con-

page_text: stantly immersed in the flushing tanks of w.c.'s, lavatories, and the like for
automatically disinfecting the discharge of the contents of same substantially,
as herein described.
