Year: 1879

page_text: LETTERS PATENT to Jonathan Scharr, of Bradford, in the County of York,
Soap Manufacturer, for the Invention of "A NEW AND IMPROVED SOAP TO BE
USED AS A SUBSTITUTE FOR OIL IN THE PREPARATION OF WOOL OR OTHER
FIBRES FOR SPINNING AND MANUFACTURING PURPOSES."
PROVISIONAL SPECIFICATION left by the said Jonathan Scharr at the
Office of the Commissioners of Patents on the 22nd February 1879.
JONATHAN SCHARR, of Bradford, in the County of York, Soap Manufacturer. "A
NEW AND IMPROVED SOAP TO BE USED AS A SUBSTITUTE FOR OIL IN THE PREPARA-
TION OF WOOL OR OTHER FIBRES FOR SPINNING AND MANUFACTURING PURPOSES."
My Invention relates to manufacturing or making a soap, which I call " soap
cream," as a substitute for oil, which is especially adapted for the combing and
carding of wool and woollens and other fibrous substances, producing brighter
colours in dyed yarns or fabrics than are produced in wool or fibres combed with
ordinary oil, rendering the fibres better for spinning and at considerably less cost.
For this purpose 1 employ to make 100 gallons of "soap cream
the following
ingredients, and in about the same quantities as herein mentioned, that is to say,
more or less according to requirements, the proportions being slightly varied :—
lha
"

page_text: pearl ash, and borax in the proportions hereinbefore named or slightly varied, and
boil the ingredients about two hours, and then add the olive oil and boil for a short
time longer.
During the boiling of the above named ingredients I dissolve the thao and gum
tragacanth by steeping and boiling them after, and when dissolved I mix the
salicylic acid & glycerine with the thao and gum tragacanth, and then add the
dissolved and mixed ingredients with those previously boiled, and leave the
ingredients to cool, and then stir them well until thoroughly well mixed.
I may employ, instead of the Marseilles soap and olive oil, other kinds of soaps
and oils, and also seaweed.

the said Jonathan Scharr in the Great Seal Patent Office on the 22nd August
1879.
JONATHAN SCHARR, of Bradford, in the County of York, Soap Manufacturer. "A
NEW AND IMPROVED SOAP TO BE USED AS A SUBSTITUTE FOR OIL IN THE PRE-
PARATION OF WOOL OR OTHER FIBRES FOR SPINNING AND MANUFACTURING
PURPOSES."
My Invention relates to manufacturing or making a soap which I call " soap-
cream," as a substitute for oil, which is especially adapted for the combing and
carding of wool and woollens and other fibrous substances, producing brighter
colours in dyed yarns or fabrics than are produced in wool or fibres combed with
ordinary oil, rendering the fibres better for spinning, and at considerably less
cost.
To carry out my Invention in practice I employ, to make 100 gallons of "soap
cream," the following ingredients, and in about the same quantities as herein mon-
tioned, that is to say, more or less according to requirements, the proportions being
slightly varied :-
Marseilles soap
Carbonate of soda
-
55 lbs.
Pearlash
Borax
Olive oil
6 lbs. 4 oz.
6 lbs. 4 oz
3 lbs. 8 oz.
175 lbs.
2 lbs.
9 oz.
-
1 lb.
8 oz.
-
9 oz.
37 lbs.
Thao (Chinese or Japanese isinglass)
Gum tragacanth
Salicylic acid
Glycerine
The "soap-cream" is prepared in the following manner :-In about 40 gallons of
water I place the Marseilles soap, carbonate of soda, pearlash, and borax in the
proportions herein before named or slightly varied, and boil the ingredients about
two hours, and then add the olive oil, and boil for a short time longer.
During the boiling of the above named ingredients I dissolve the thao and gum
tragacanth by steeping and boiling them after, and when dissolved, I mix the
salicylic acid and glycerine with the thao and gum tragacanth, and then add the
dissolved and mixed ingredients with those previously boiled, and leave the
ingredients to cool, and then stir them well until thoroughly well mixed.
Sometimes I manufacture a modified form of soap cream by varying the above
process as follows:-
I steep in water (in proportion to the quantity to be made) 2 lbs. 8 oz. gum
tragacanth, and 4 lbs. 8 oz. thao for about 12 hours, after which I boil both
ingredients for about one hour, and when thoroughly dissolved, I add 34 lbs.
glycerine and 6 oz. salicylic acid, and boil it half an hour longer. I dissolve in
another receptacle 48 lbs. Marseilles soap, and add, when thoroughly dissolved,
134 lbs. olive oil, and boil for half an hour slowly. When these have been boiled
as stated above, I mix both boilings together, and boil the whole 15 minutes slowly.
Japanese or Chinese isinglass, also Irish moss, may be used instead of the thao.
Thao can also be mixed with the above named ingredients, in which case less thao
must be used in proportion to the above named ingredients. I may employ instead
of the Marseilles soap and olive oil, other kinds of soaps and oils, and also
seaweed.
Having now particularly described and ascertained the nature of the said Inven-
tion, and in what manner the same is to be performed or carried out in practice,
I hereby declare that I claim the Invention of "A New and Improved Soap to be

page_text: Used as a Substitute for Oil in the Preparation of Wool or other Fibres for Spinning
and Manufacturing Purposes," substantially as hereinbefore set forth and described.
In witness whereof, I, the said Jonathan Scharr, have hereunto set my hand
and seal, this Nineteenth day of August, in the year of our Lord One
thousand eight hundred and seventy-nine.
Witness,
WILLIAM LOBLEY.
