I, WILLIAM LLOYD WISE, of N° 46 Lincoln's Inn Fields, in the County of
Middlesex, Consulting Engineer and Patent Agent, do hereby declare the nature
of said invention for "IMPROVEMENTS IN MEANS FOR RENDERING FABRICS AND
OTHER SUBSTANCES UNINFLAMMABLE OBNOXIOUS TO VERMIN, RESISTANT TO PUTRE-
FACTION, TO THE RECEPTION OF MORBID OR DISEASED MATTER, AND TO THE GROWTH
OF SPORES, FUNGI, BACTERIA AND THE LIKE" (a communication to me from abroad
by Josef Ferdinand Notz, of Dresden, Saxony, Merchant, and Franz Konrad, of
Zschieren near Dresden, Engineer) to be as follows:-
The improvement in the means for rendering fabrics and other substances
uninflammable, obnoxious to vermin, resistant to putrefaction, to the reception of
morbid or diseased matter and to the growth of spores, fungi, bacteria etcetera is
mainly attained by adding certain substances and the method of adding to the
composition which is specified in the U.S. Patent N° 308679 dated December 2.
1884 to Franz Konrad one of the communicators to me of the present invention,
thereby rendering it more suitable for the purpose.
The solution employed according to the above named patent is prepared as
follows:-
To 90 Kilogrammes (equal to 90 litres) of water, are added 10 Kilogrammes
of sulphate of ammonia, one Kilogramme of carbonate of ammonia, one half
(3) kilogramme of borax, one tenth (1) kilogr: of bi-chloride of mercury; and a
decoction of peppermint, which is produced by extracting 2 Kilogrammes of
peppermint (plant with blossom but without root) in 6 kilograinmes of water at
85° Celsius; also 150 gramme of carbolic acid, which at 20° Celsius has a specific
gravity of about 1·062,

page_text: The improvement in the above solution consists in adding to the above ingredients
after they have been well mixed and dissolved 6 kilogrammes of tungstate of soda
dissolved in 94 kilogrammes of water and immediately after this addition so much
of a saturated solution of chloride of lime (one part of chloride of lime to ten
parts of water) as will be necessary to prevent precipitation or crystallisation of
any salt or salts and keep the solution liquid.
This liquor is put into a vessel provided with an agitator, capable of thoroughly
mixing the composition and of keeping it in a highly agitated state during the
following process in which the composition is transformed into an emulsion.
In this vessel the liquor is to be kept at about by any suitable means of
heating.
55° R
The vessel is connected by a pipe which ends or terminates below the level of
the liquor, to a retort, into which is poured a solution obtained by dissolving
one kilogramme of Peru Balsam and 0.3 (10) of a kilogramme of camphor in
2 kilogrammes of ether. I do not bind myself to any particular ether, but it has
been found that acetic ether will answer the purpose well.
This solution is distilled off in the retort by means of a moderate heat, the
products of distillation being absorbed by or incorporated in the well agitated
liquor which is constantly kept at about the temperature above specified.
The final product will be a diluted emulsion capable of easily being absorbed or
sucked up by any fabrics or other substance immersed into the emulsion.
This method of treating fabrics or other substances will improve their quality,
render them aromatic, and more obnoxious to vermin such as acarus exulcerans or
other insects and the disadvantage of the inflammability of the Peru Balsam is
obviated by the method by which it is added to the liquor and by adding to the
solution the fireproof ingredient which so diminishes the inflammability of the
fabric or other substance that it will only smoulder or char on the application of
a flame.
These improved qualities are not transient but will last as long as the fabric or
other substance is fit for use.
Although I have given proportions or weights that have been found to answer
the purpose well, it is to be understood that I do not limit myself to such
proportions or weights, as they may be varied without departing from the essence
of the invention.

I, WILLIAM LLOYD WISE, of N° 46 Lincoln's Inn Fields in the County of
Middlesex, Consulting Engineer and Patent Agent, do hereby declare the nature
of this invention (a communication to me from abroad by Josef Ferdinand Notz, of
Dresden, Saxony, Merchant, and Franz Konrad, of Zschieren near Dresden,
Engineer) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The improvement in the means for rendering fabrics and other substances
uninflammable, obnoxious to vermin, resistant to putrefaction, to the reception of
morbid or diseased matter, and to the growth of spores, fungi, bacteria and the
like, is mainly attained by adding certain substances and the method of adding
them to the composition which is set forth in the Specification of United States
Patent No 308679 dated December 2nd 1884 granted to Franz Konrad one of the
communicators to me of the present invention thereby rendering it more suitable
for the purpose.
The solution or composition employed according to the above named patent is
prepared as follows.
To 90 kilogrammes (equal to 90 litres) of water are added 10 kilogrammes of
sulphate of ammonia, one kilogramme of carbonate of ammonia, one half (1) kilo-
gramme of borax, one tenth (16) kilogramme of bi-chloride of mercury; and a
decoction of peppermint, which is produced by extracting 2 kilogrammes of
peppermint (plant with blossom but without root) in 6 kilogrammes of water at
85° Celsius; also 150 grammes of carbolic acid, which at 20° Celsius has a specific
gravity of about 1.062.
The improvement in the above solution consists in adding to the above
ingredients after they have been well mixed and dissolved 6 kilogrammes of bi-
tungstate of soda dissolved in 94 kilogrammes of water and immediately after the
addition of this solution so much of a saturated solution of chloride of lime (one
part of chloride of lime to ten parts of water) as will suffice to prevent any
solidification of the liquid or any precipitation or crystallisation of double salts
formed by the admixture of the above ingredients.
The liquid thus obtained is put into a vessel provided with an agitator in order
to very intensely agitate or stir the liquid for the following process, in which the
composition is transformed into an emulsion. In this vessel the liquor is to be
kept at about 70°σ by any suitable means of heating.
65° R
The vessel is connected by a pipe to a retort, into which latter I introduce a
solution obtained by dissolving one kilogramme of Peru balsam and 0.3 (1%) of
a kilogramme of camphor in 2 kilogrammes of ether. My foreign correspondents

page_text: have found acetic ether to answer the purpose well, but I do not limit myself to
this specific ether.
This solution is distilled off in the retort by a moderate heat, the products of
distillation being conducted into the well agitated and stirred liquid which is
constantly kept at about the temperature above specified.
The final product will be a diluted emulsion capable of easily being absorbed or
sucked up by any fabrics or other material immersed into the emulsion.
This method of treating fabrics or other materials will improve their quality,
render them aromatic and more obnoxious to vermin such as acarus exculcerans or
other insects and the disadvantage of the inflammability of the Peru Balsam is
obviated by the method by which it is added to the liquor and by adding to the
solution the fireproof ingredient which so diminishes the inflammability of the
fabric or other substance that it will only smoulder or char on the application of a
flame.
I wish it expressly understood that such action of the liquid on the fabrics is
not transitory, requiring frequent repitition, but will last as long as the fabric or
other substance is fit for use.
Although my foreign correspondents have found the proportions or weights of
materials employed as above stated as best for the purpose I do not limit myself
to these proportions or weights, as they may be varied without departing from the
invention.
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 I do
not claim the separate use of the ingredients named in this specification, but what
I claim is
The composition of a liquid for rendering fabrics or other substances unin-
flammable, repellent to vermin, and counteractive to morbid or diseased matter or
the infection from spores, fungi, bacteria etc, which composition consists of a
solution of sulphate of ammonia, carbonate of ammonia, borax, bi-chloride of
mercury, peppermint, carbolic acid, bi-tungstate of soda, and chloride of lime
transformed into an emulsion by leading into the solution the products obtained
from the distillation of a solution of Peruvian balsam and camphor substantially
as set forth.
