An Improved Sterilizing, Disinfecting, and Deodorizing Fluid,
applicable also for Use as an Insecticide.
I, CHARLES THOMAS GARDNER, of 10, Sussex Road, Worthing, in the County
of Sussex, Sanitary Engineer, 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 :—
This invention relates to an improved sterilizing disinfecting and deodorizing
fluid, the object being to produce a fluid which will very rapidly sterilize disinfect
and deodorize fæcal and other offensive and deleterious matter by direct action
thereon.
According to my invention this fluid is prepared by adding to distilled water
chlorinated lime or a suitable bleaching powder and adding also potash or pearlash
sodium chloride alum borax in combination or otherwise. To the resulting
compound solution I may add any suitable scenting or colouring agent.
Instead of distilled or sterilized water I may use ordinary water but I prefer
distilled water.
The use of distilled or sterilized water in the compound solution is of advantage
for the purposes of this invention inasmuch as it increases the efficacy of the
solution beyond that which it would possess if undistilled or non-sterilized water
were employed instead as may be done in case of need.
I do not desire to limit this invention to the use of particular proportions of the
components of the compound solution but the following is a statement by way of
example of one mode of carrying out my invention ;-
Let a saturated solution of chlorinated lime or of a suitable bleaching powder be
prepared and the specific gravity of which should be approximately 1050 when
the solution is free of the base and quite clear; to every 100 parts by volume of this
solution hereinafter termed the standard solution add one part by volume of a
solution of potash or pearlash_sodium chloride or of borax soda or alum which
should be saturated solutions. The resulting compound solution will be of suitable
strength for most ordinary purposes.
I find that one pound of good commercial chlorinated lime added to one gallon
of distilled water will make the standard chlorinated solution; but if a stronger
chlorinated solution be required or a weaker solution as the case may be I vary
accordingly the quantity of the chlorinated lime or bleaching powder or dilute the
standard solution.
Instead of adding the above-stated proportion of only one of the several solutions
to the standard solution I form that one part or proportion as a mixture of any two
or more of such solutions but it is not necessary to use more than 50 per cent. of
such parts. For instance if the mixed solutions constituting my improved fluid are
to be used for purifying infected paint or woodwork, such as ship's decks or cattle-
pens I use more than the one part or proportion and employ the pearlash and soda
solutions together as an addition to the standard solution. Or if it is desired that
one part or element of the matter treated be not affected I omit from the solution
any ingredient which would be likely to act up
upon it.
For scenting or colouring the compound solution I may add to it eucalyptus oil
camphor spirits or any other suitable scenting or colouring ingredient.
My improved fluid will act hygienically upon most materials which give off
sulphuretted or phosphoretted hydrogen or other offensive or injurious exhalations

page_text: or effluvia; or upon the effluvium arising from excreta or from decaying animal or
vegetable matter. The said fluid is clear and does not tend to choke drains; it
prevents the adherence of fæcal matter to sick-room or hospital appliances and
prevents such matter from acting corrosively in latrines, urinals, soil-pipes and
drain pipes. Furthermore my improved fluid is useful as an insecticide.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. A fluid for the purposes specified containing the described ingredients in or
about in the proportions mentioned.
2. A fluid containing one hundred parts by volume of the described standard
chlorinated solution and one part by volume of a solution or of mixed solutions of
potash or pearlash sodium chloride soda alum borax with or without scenting or
colouring matter for the purposes specified.
3. In a fluid of the kind described in the two preceding claiming clauses the
employment of distilled or of sterilized water for the purpose specified.
4. A fluid of the kind described in the three preceding claiming clauses but
containing a larger or smaller proportion of the chlorinated solution than the one
hundred parts specified.
Dated this 28th day of November 1894.
