TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
LITTLE of Heckington Hall near Sleaford in the County of Lincoln send greeting
WHEREAS Her Most Excellent Majesty Queen Victoria by Her Royal Letters
Patent under the Great Seal of Great Britain and Ireland bearing date at West-
minster the eighteenth day of January in the year of our Lord One thousand
eight hundred and seventy six in the thirty ninth year of Her Reign did for
herself her heirs and Successors give and grant unto me the said William Little
my executors administrators or assigns especial license full power sole privilege
and authority that I the said William Little my executors administrators or
assigns and every one of them by myself and themselves or by my and their
Deputy or Deputies Servants or Agents or such others as I my executors
administrators or assigns should at any time agree with and 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 of
"IMPROVEMENTS IN THE MANUFACTURE OF CLEANSING AND DISINFECTING FLUIDS
FOR WASHING SHEEP AND FOR OTHER PURPOSES for and during the term of
fourteen years thence next ensuing And whereas in pursuance and performance of
a proviso in the said Letters Patent contained I the said William Little did within
six calendar months next after the date of the said Letters Patent cause a Specifi-
cation in writing under my hand and seal purporting to particularly describe the
nature of the said Invention and in what manner the same was to be performed
to be duly filed in the Great Scal Patent Office And whereas since the date of the
said Specification I have been advised that it is doubtful if the admixture of
bisulphide of Carbon with the other materials described and claimed in the said
Specification can be properly claimed under the said Letters Patent and I have
also ascertained that such admixture of bisulphide of Carbon has not been found
to be useful or beneficial NOW KNOW YE that I the said William Little by
and with the leave of Her Majesty's Solicitor General and for the reasons aforesaid
do alter and amend the said Specification in manner following (that is to say)
I strike out of the Specification printed by the Queen's Printers and published at
the Great Seal Patent Office in one thousand eight hundred and eighty one (Second
Edition) the words "and bisulphide of carbon" occurring in the claiming clause of
the said Specification at lines 38 and 39 of page 2 and I insert after the words
"bisulphide of carbon" which occur in line 36 of the same page the words " but I
do not claim this admixture as any part of my said Invention And in order that
the effect of the Disclaimer and Memorandum of Alteration as aforesaid may be
clearly understood I annex hereto a copy of the said Specification as it will appear
when so altered and amended the preamble and testing clause being omitted.
This Invention has for its object Improvements in the manufacture of cleansing
and disinfecting fluids for washing Sheep and for other purposes.

page_text: First, I take Gas tar, preferring such as is not overcharged with naphthaline.
I subject this tar to one or more careful distillations, dividing the products of
each distillation into three parts, videlicet, those that have a specific gravity lighter
than water, those that have a specific gravity heavier than water and those that
distil at a high temperature, and are known as green or anthracine oil.-The
products lighter than water I distil again by which I get an additional portion of
the oil heavier than water, the light oil I set aside; the green or anthracine oil,
after the extraction of the anthracine by the usual process, I return to the inter-
mediate oil, and if thought desirable I subject the whole to a further purification
by another distillation. In place of these products from gas tar other such like
products may be employed but less advantageously.
Second, I take ordinary resin which I subject to distillation and the product to
another distillation if desirable for the purpose of purification.
Third, I take animal or vegetable oil of the purest kind, preferring such as
are free from stearine. I boil this oil with a solution of caustic potash in the
usual way until I obtain a perfect form of olente of potash. The oleate of potash
should be transparent and consist in one hundred parts, about 43 oil, 10 Potash
and 47 water.
Fourth, I make a solution of Caustic Soda in water containing ten per cent of
pure soda.
Fifth, I then mix one thousand pounds of the hydrocarbon Oil with five hundred
pounds of the purified resin Oil and let the combined Oils stand for twenty four
hours.
Sixth, I then put one hundred pounds of the oleate of Potash into a boiler and
mix it by a gentle heat with one hundred pounds of the mixed resin and hydro-
carbon oils and when combined I add it to the rest of the mixed oils and stir well
together. After standing twenty four hours I add nine gallons of the Solutions of
Soda and stir well together.
Seventh, And lastly, when cold and when required for use at certain Seasons to
prevent the attack of the maggot or blue fly, I mix well with the rest ten pounds
by weight of bisulphide of Carbon, but I do not claim this admixture as any part
of my said Invention.
I claim the combination of the distilled products from gas tar (or other such like
products) with resinous matter, oleate of potash and solution of Soda so as to make
a liquid chemical combination (and not a mixture in which the component parts
are held in suspension) mixable in any proportion with water to which I give the
title of Little's Chemical Fluid and Disinfectant.
In witness whereof I the said William Little have to this my Disclaimer
set my hand and Seal this twenty sixth day of July One thousand eight

"IMPROVEMENTS IN THE MANUFACTURE OF CLEANSING AND DISINFECTING FLUIDS
FOR WASHING, SHEEP AND FOR OTHER PURPOSES."
This Invention has for its object improvements in the manufacture of cleansing
and disinfecting fluids for washing sheep and for other purposes.
1. I take gas tar, preferring such as is not overcharged with naphthaline. I
subject this tar to one or more careful distillations, dividing the products of each
distillation into three parts, viz., those that have a specific gravity lighter than
water, those that have a specific gravity heavier than water, and those that distil
at a high temperature and are known as green or anthracine oil. The products
lighter than water I distil again, by which I get an additional portion of the oil
heavier than water; the light oil I set aside; the green or anthracine oil after the
extraction of the anthracine by the usual process I return to the intermediate oil,
and if thought desirable I subject the whole to a further purification by another
.distillation. In place of these products from gas tar other such like products may
be employed but less advantageously.
2. I take ordinary resin which I subject to distillation, and the product to
another distillation if desirable for the purpose of purification.
3. I take animal or vegetable oil of the purest kind, preferring such as are free
from stearine. I boil this oil with a solution of caustic potash in the usual way
until I obtain a perfect form of oleate of potash. The oleate of potash should be
transparent and consist in 100 parts, about 43 oil, 10 potash, and 47 water.
4. I make a solution of caustic soda in water containing 10 per cent. of pure
soda.
5.1 then mix one thousand pounds of the hydrocarbon oil with five hundred
pounds of the purified resin oil and let the combined oils stand for 24 hours.
6. I then put one hundred pounds of the oleate of potash into a boiler and mix it
by a gentle heat with one hundred pounds of the mixed resin and hydrocarbon oils,
and when combined I add it to the rest of the mixed oils and stir well together.
After standing 24 hours I add nine gallons of the solution of soda and stir well
together.
7. And, lastly, when cold and when required for use at certain seasons to prevent
the attack of the maggot or blue fly I mix well with the rest ten pounds by weight
of bisulphide of carbon.
I claim the combination of the distilled products from gas tar (or other such like
products) with resinous matter, oleate of potash, and solution of soda and bi-sulphide
of carbon so as to make a liquid chemical combination (and not a mixture in which
the component parts are held in suspension), mixable in any proportion with
water, to which I give the title of Little's Chemical Fluid and Disinfectant.
In witness whereof I, the said William Little, have hereunto set my hand
aud seal, this Fourteenth day of July, in the year of our Lord One thousand
eight hundred and seventy-six.
