for the Invention of "AN IMPROVED GELATINOUS AND ECONOMICAL SOAP."-
A communication.
Sealed the 30th January 1857, and dated the 30th July 1856.
PROVISIONAL SPECIFICATION left by the said Julien Denis at the Office
of the Commissioners of Patents, with his Petition, on the 30th July
1856.
I, JULIEN DENIS, of Queenhithe, in the City of London, do hereby declare
the nature of the said Invention for "AN IMPROVED GELATINOUS AND ECONOMICAL
SOAP," (a communication,) to be as follows:-
This new kind of soap is composed of the following ingredients
Best curd or white soap, about
Pearlash,.
Quicklime,
- 2 lbs.
do.
-
1 lb.
do.
-
of a lb.
Chloride of lime pulverized do.
Gelatine (osteocolle)
about
th part of a pound..
two ounces.
These substances are mixed together in the following manner :-The curd
soap is first cut into thin slices, & placed in an earthenware or wooden
5 recipient of sufficient dimensions to contain eleven quarts; 2°, the quicklime is
placed in another recipient, & diluted in about a quart of water; 3º,. the

page_text: chloride of lime is likewise diluted in the same proportion of water, and left to
settle; 4°, the pearlash is placed in a copper or cast-iron vessel with about
seven quarts of water; the vessel is then placed on the fire, and when the
pearlash is dissolved, the diluted lime is added & left to boil about 30
minutes, taking care to stir frequently the liquid after the ebullition; the sd
liquid is poured into another vessel, & the chloride of lime is mixed with it.
The liquid, thus prepared, is poured on the slices of soap afore-mentioned, &
on the residue remaining attached to the bottom of the vessel that contained
the liquid about 5 quarts of boiling water are poured in; the residuum is then
stirred, & becomes incorporated with the mass of water; after allowing the
-whole-to-repose sometime,_this_liquid is poured on the soap, the stirring is
continued until the soap be completely dissolved. 6°, the gelatine (or
osteocolle) is then thrown into a quart of boiling water, &, when dissolved
thoroughly, mixed with the whole mass of ingredients. Thus, about 22 lbs. of
gelatinous soap will be obtained. The method of using this soap should be
(when employed for cleansing linen, as follows:-The linen, according to its
degree of fineness or coarseness, is left to soak 6 or 12 hours; the linen is
then wrung, and placed in a copper filled with a solution of the soap, of which
about 2 lbs. are thrown in for about every two gallons & a half of water.
From 25 to 40 minutes are sufficient to cleanse the linen.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Julien Denis in the Great Seal Patent Office on the

no others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man,. an Invention. for "AN IMPROVED GELATINOUS AND
.

page_text: ECONOMICAL SOAP," "a communication," upon the condition (amongst others) that
I, the said Julien Denis, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Julien Denis, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This new kind of soap is composed of the following ingredients in or about
the proportions indicated:-
Best curd or white soap
Pearlash
Quicklime
Chloride of lime in powder
2 lbs.
-
1 lb.
-
of a lb.
ath of a lb.
2 ounces.
Gelatine (osteocolle)
The above ingredients are mixed together in the following manner :-The
curd soap is first cut into thin slices, & thrown into an earthenware or
wooden recipient of dimensions sufficient to allow it to contain eleven quarts
of the improved gelatinous soap, which, when manufactured, is in the stato
of a jelly or soft paste, the quicklime is then placed in another recipient, and
diluted in about a quart of water.
This being effected, the chloride of lime is likewise diluted in the same
proportion of water, & left to settle. After this, the pearlash is placed in a
copper or cast-iron vessel, with about seven quarts of water; the said vessel is
then put on the fire, and when the pearlash is dissolved, the diluted lime
is added, & both left to boil during half an hour; care must be taken to stir
frequently the liquid, which, after that time of ebullition, must be poured into
another vessel, into which the diluted chloride of lime, must also be decanted
& mixed with the liquid in the said vessel. The liquid thus prepared is poured
upon the slices of soap aforesaid, & on the dregs remaining attached to the
bottom of the vessel that contained the liquid are poured about 5 quarts of
boiling water. By agitating frequently the dregs, they melt and form one
mass with the water; after allowing the whole mass to repose some time this
liquid is poured upon the soap.
The gelatine (or (osteocolle) is then thrown into a quart of boiling water,
& when dissolved, thoroughly mixed with the whole mass of ingredients; thus,

page_text: about 22 lbs. of soap will be obtained. When this soap is used to bleach
linen, it should be employed in the following manner :-The linen, according
to its fiueness or coarseness, is left to soak from 6 to 12 hours, after which it is
wrung & placed in a copper filled with a solution of the soap, of which about
2 lbs. are thrown in for about every 2 gallons & a half of water. From 25
to 40 minutes boiling are sufficient to cleanse the linen.
Having now duly described and ascertained the nature of the said Invention,
I claim as novel the mixture of the ingredients herein stated as composing the
new gelatinous soap, and likewise the manner herein described of mixing the
said ingredients, but I do not limit myself to the exact proportions of the said
