I, WILLIAM JOHN COOPER, of 7 Westminster Chambers, Victoria Street, in the
City of Westminster, Analytical Chemist, do hereby declare the nature of this
Invention to be as follows:-
The object of my Invention is to obtain a very efficient antiseptic or disinfectant
suitable for disinfecting and preservative purposes generally. The antiseptic or
disinfectant compounded according to my Invention consists of Chloride of Calcium,
Chloride of Sodium and Camphor. These are taken in a solid and finely divided
form and are thoroughly incorporated and to facilitate the incorporation they may be
reduced or powdered after being added together. The proportions I prefer are about
34 parts by weight of anhydrous Chloride of Calcium and 66 parts by weight of the
Chloride of Sodium. A proportion of Camphor of 2 lbs. of Camphor to each ton
of the other ingredients will be sufficient. I do not limit myself to the precise
proportions before stated.
The antiseptic or disinfectant may be used in a dry state or as a solution by
dissolving two lbs. of the mixture in a gallon of water.

England, Analytical Chemist 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 object of my invention is to obtain a very efficient Soluble Antiseptic or
disinfectant suitable for disinfectant and preservative purposes generally.
The antiseptic or disinfectant, compounded according to my invention consists of a
mixture of Chloride of Calcium and Chloride of Sodium with or without an admixture
of Camphor.
To prepare the antiseptic or disinfectant these substances may be taken in a finely
divided state and thoroughly intermixed. To facilitate the intermixture they may be
reduced or powdered after being added together. The proportions I prefer are about
thirty four parts by weight of anhydrous Chloride of Calcium and sixty six parts
by weight of the Chloride of Sodium-A proportion of Camphor of two and a half
pounds of same to each ton of the other ingredients will be sufficient for general uses
but I do not of course confine myself to the proportions above stated.
The antiseptic or disinfectant may be used in a dry or powdered state, or when a
disinfecting or antiseptic solution is desired it may be prepared by dissolving about
two pounds of the mixed substances in a gallon of water.
When the disinfectant is to be used in a solid form as is frequently desirable in
Sinks, Urinals and like places, the proportion of camphor may with advantage be
considerably increased until in fact the mixture contains one half of its weight in
camphor-The primary object of the Camphor in such a case is to prevent the too
rapid dissolving of the block or tablet into which the mass may conveniently have
been formed, although of course the beneficial effects which many believe Camphor
to possess, and the odour, will be more marked as the proportion thereof is
increased.
On the other hand when the object is to disinfect drains or Sewers the Camphor
may be entirely omitted as the simple mixture of the Chlorides of Calcium and
Sodium will be found efficacious.
I am aware that admixtures of Chlorides of Calcium and Sodium have previously
been proposed for different purposes, but so far as I know prior to my invention no
one has proposed to combine them in such proportions with or without an admixture
of Camphor as will produce an efficacious antiseptic and disinfectant which will be
soluble in water and other liquids and consequently incapable of choking waste or
other pipes Sewers or the like."

page_text: 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 is :-
First. As an article of manufacture an antiseptic or disinfectant composed of a
mixture of Chloride of Calcium and Chloride of Sodium substantially in the
proportions specified.
Second. As an article of manufacture an antiseptic or disinfectant composed of a
mixture of Chloride of Calcium, Chloride of Sodium and Camphor substantially as
set forth.
