PROVISIONAL SPECIFICATION.
Improvements in Disinfectants and Deodorizers.
I, JOSEPH PRICE, of 58 Lombard Street, in the City of London Accountant, do
hereby declare the nature of this invention to be as follows:-
The main object of my invention is the preparation of a compound or admixture of
certain chemical substances for disinfecting, deodorizing, and purifying infectious,
offensive and noxious gases and foul or decaying vegetable or animal matters, such
compound being not only efficacious and portable but more useful and economical than
any preparation for similar purposes in ordinary use.
It is well known that oxygen and chlorine are the most powerful disinfectants yet
discovered, and that their combination with any substance in a portable or convenient
state for dealing with offensive effluvia, or decomposing and putrescent matters is an
object worthy of attainment, as such a compound would do double duty by readily
attacking impurities contaminating the atmosphere or escaping from aqueous bodies,
as well as arresting the decomposition of, and purifying the offensive animal and
vegetable inatters therein contained.
The methods which have been proposed for accomplishing these desiderata have
always had some disadvantage, the materials employed to hold the two gases, oxygen
and chlorine, in combination, were either too expensive or unsuitable for commercial
purposes.
The materials I prefer to employ are manganate of soda and chloride of lime, but
I may use other compounds containing oxygen and chloride, and I mix or blend
these with a, comparatively speaking, waste chemical product, known as "Salt Cake
(sulphate of soda) the residuum from the chemicals used in the manufacture of
muriatic, nitrous, or nitric acids, which is in itself a highly antiseptic salt.
This combination has many advantages over other disinfectants, which usually
contain only one of the two principal elements in question, and are often mixed with
lime, chalk, terra alba, sawdust, or other indissoluble matters, which choke up the
drains and sewers. 1 prepare my compound in a perfectly free and dry state, in
which condition it may be used and when exposed in shallow or other vessels it emits
chlorine in a steady continuous and effective manner for a week or ten days, without
appreciably deliquescing, destroying all noxious and offensive smells within a wide
radius, and it is, after the exposure, almost as efficacious (having acquired additional
oxygen whilst emitting the chlorine) for treating foul water and putting down sinks,
drains, water closets &c., as when used direct for such purposes.
Another very important feature in my preparation consists in its solubility in
water and it therefore will not choke up or clog the drain pipes, or sewers, and
consequently it is especially adapted for household purposes, barracks, hospitals,
workhouses, stables, or other buildings draining into the common sewers, where
it would finish its work by destroying the foul gases and purifying the fluid
matters.
From experience, I find that the most suitable proportions of the ingredients
which I combine for the purposes enumerated, having all ends in view, are as
follows:
1 part manganate of soda,
parts chloride of lime,

"
salt cake (sulphate of soda),

page_text: most valuable adjunct to the other purifying agents, which combined, would serve to
prepare sewage matters for treatment at the outfall, the ammoniacal and nitrogenous
properties being fixed ready for precipitation-hence it would greatly enhance the
value of the deposit by rendering it a highly fertilising commodity for agricultural
purposes.
I purpose calling my new compound "Sal-Ozone” and to use it for disinfecting,
deodorising, and neutralising, noxious, and offensive, effluvia, and decomposing or
putrescent animal or vegetable matters. It is found to be effective, innocuous,
portable, and economical, and can be used in a dry or liquid state, and being soluble,
is eminently suited for putting down sinks, drains, or sewers, to neutralize sewer gases
and arrest decomposition in the sewerage matters.
It does not destroy but adds to the valuable fertilising properties contained therein,
and such sewerage matters can after treatment with my preparation be therefore
profitably utilised for agricultural purposes.

COMPLETE SPECIFICATION.
Improvements in Disinfectants and Deodorizers.
I, JOSEPH PRICE, of 58 Lombard Street, in the City of London, Accountant, 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 main object of my invention is the preparation of a compound or admixture
of certain chemical substances for disinfecting, deodorising, and purifying infectious,
offensive and noxious gases, and foul or decaying vegetable or animal matters, such
compound being not only efficacious and portable but more useful and economical than
any preparation for similar purposes in ordinary use.
It is well known that oxygen and chlorine are the most powerful disinfectants yet
discovered, and that their combination with any substance in a portable or convenient
state for dealing with offensive effluvia or decomposing and putrescent matters, is an
object worthy of attainment, as such a compound would do double duty, by readily
attacking impurities contaminating the atmosphere, or escaping from aqueous bodies,
as well as arresting the decomposition of and purifying the offensive animal and
vegetable matters therein contained.
The methods which have been proposed for accomplishing these desiderata have
always bad some disadvantage, the materials employed to hold the two gases, oxygen
and chlorine, in combination, were either too expensive or unsuitable for commercial
purposes.
The materials I prefer to employ, are manganate of soda and chloride of lime, but
I may use other compounds containing oxygen and chlorine, and I mix or blend these
with a comparatively speaking waste chemical product known as "Salt Cake" (sul-
phate of soda) the residuum from the chemicals used in the manufacture of muriatic,
nitrous, or nitric acids, which is in itself a highly antiseptic salt.
This combination has many advantages over other disinfectants, which usually
contain only one of the two principal elements in question, and are often mixed with
lime, chalk, terra-alba, sawdust, or other indissoluble matters, which choke up the
drains and sewers.
prepare my compound in a perfectly dry and free state in
which condition it may be used and when exposed in shallow or other vessels, it
emits chlorine in a steady, continuous and effective manner for a week or ten days
without appreciably deliquescing, destroying all noxious and offensive smells within a
wide radius, and it is after this exposure almost as efficacious (having acquired
additional oxygen whilst emitting the chlorine for treating foul water, and putting
down sinks, drains, water closets, &c., as when used direct for such purpose.

consequently is specially adapted for household purposes, barracks, hospitals, work-
houses, stables, or other buildings, draining into the common sewers, where
it would complete its work by destroying the foul gases and purifying the fluid
matters.
From experience I find that the most suitable proportions of the ingredients
which I combine for the purposes enumerated, having all ends in view, are as
follows:-
1
part manganate of soda,
1
parts chloride of lime,
17
parts salt cake (sulphate of soda),
but I may vary or determine the proportions under special circumstances and
conditions which might present themselves in practice.
As the salt cake contains a small portion of free hydrochloric or nitric acid, it is
a most valuable adjunct to the other purifying agents, which combined would serve
to prepare sewage matters for treatment at the outfall, the ammoniacal and
nitrogenous properties being fixed ready for precipitation-hence it would greatly
enhance the value of the deposit by rendering it a highly fertilising commodity for
agricultural purposes.
I propose calling my new compound "Sal-Ozone," and to use it for disinfecting,
deodorising, and neutralising noxious and offensive effluvia and decomposing or
putrescent animal or vegetable matters. It is found to he effective, innocuous,
portable and economical, and can be used in a dry or liquid state, and being
soluble is eminently suited for putting down sinks, drains, or sewers, to neutralise
sewer gases, and arrest decomposition in the sewerage matters. It does not destroy
but adds to the valuable fertilising properties contained therein, and such sewerage
matters can after treatment with my preparation be therefore profitably utilised for
agricultural purposes.
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. A disinfectant and deodorizer, composed of a mixture or combination of salt
cake (sulphate of soda) with suitable proportions of manganate of soda and chloride
of lime, for the purposes as herein set forth.
2. A disinfectant and deodorizer, composed of a mixture or combination of salt
cake (sulphate of soda) with suitable compounds or substances containing oxygen and
chlorine, for the purposes as herein set forth.
