Year: 1866

page_text: LETTERS PATENT to John Graham Hope, of Edinburgh, in the County
of Mid Lothian, North Britain, Manufacturing Chemist, for the Invention
of "AN IMPROVED COMPOSITION FOR DESTROYING VERMIN ON SHEEP AND
Sealed the 30th October 1866, and dated the 4th May 1866.
PROVISIONAL SPECIFICATION left by the said John Graham Hope at
the Office of the Commissioners of Patents, with his Petition, on the
4th May 1866.
I, JOHN GRAHAM HOPE, of Edinburgh, in the County of Mid Lothian,
North Britain, Manufacturing Chemist, do hereby declare the nature of the
said Invention of "AN IMPROVED COMPOSITION FOR DESTROYING VERMIN ON SHEEP
AND OTHER ANIMALS, AND FOR PRESERVING THEM THEREFROM," to be as follows,
that is to say:
This Invention which relates to the production of a mixture or composition
for smearing sheep and other animals for the purpose of destroying vermin,
and preserving them therefrom, consists as follows:-Some of the brown
grease obtained from the refuse of wool is melted in a suitable vessel, after
which some gallipoli oil, cod oil or "foots," and some light pitch oil, are suc-
cessively introduced, some naphthaline is then added, and when these ingredients
are mixed the admixture is heated up to about the boiling point of water,.
after which an alkali of 10° Twaddle is either added to the mixture in the
vessel, or the mixture itself may be run into a vessel containing the alkali.
When the whole of the ingredients are thoroughly commingled the compound

page_text: is allowed to cool, after which it is in a fit state for use, and may be applied
either as a smear, or being dissolved in water as a dip.
In preparing the composition it is preferred to employ the following propor-
tions, although others may be used, viz. :-Brown grease, one part; gallipoli
oil, half a part; cod oil or "foots," half a part; light pitch oil, two parts;
naphthaline, one part; and alkali, one part.
In lieu of using light pitch oil alone, a mixture consisting of one-half of
light pitch oil, and the other half of shale or "green oil" may be substituted,
or in some cases shale or "green oil" may be employed entirely in sub-
stitution for the light pitch oil. The alkali which it is preferred to use
consists, one-half of soda, the other half of potash.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Graham Hope in the Great Seal Patent Office on the
1st November 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GRAHAM HOPE, of Edinburgh, in the County of Mid Lothian, North Britain,
Manufacturing Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of May, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Graham Hope, Her special license that I; the said John
Graham Hope, my executors, administrators, and assigns, or such others as
I, the said John Graham Hope, my executors, administrators, or assign's,
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
for "AN IMPROVED COMPOSITION FOR DESTROYING VERMIN ON SHEEP AND OTHER
ANIMALS, AND FOR PRESERVING THEM THEREFROM," upon the condition (amongst
others) that I, the said John Graham Hope, by an instrument in writing
under iny hand and seal, 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.

page_text: NOW KNOW YE, that I, the said John Graham Hope, do hereby declare
the nature of my said Invention; and in what manner the same is to be
performed, to be particularly described and ascertained in and. by the following
statement, that is to say :-
My said Invention relates to the production of a mixture or composition for
smearing sheep, and other animals for the purpose of destroying vermin and
preserving them therefrom; and consists as follows:-Some of the brown
grease obtained from the refuse of woollen manufactures is melted in a
suitable vessel, after which some gallipoli oil, fish oil, and some light pitch
oil are successively introduced, some naphthaline is now added. When these
ingredients are mixed the admixture is heated up to about the boiling point
of water, after which an alkali of 10° Twaddle is either added to the mixture
in the vessel, or the mixture itself may be run into a vessel containing the
alkali. When the whole of the ingredients are thoroughly commingled the
compound is allowed to cool, after which it is in a fit state for use and may be
applied either as a smear, or being dissolved in water as a dip.
In preparing the composition it is preferred to employ the following pro-
portions, although these proportions may be varied in some cases :-One part
of brown grease from the refuse of woollen manufactures; one and a half
parts of gallipoli oil; one and a half parts of fish oil; two parts of light pitch
oil; one part of napthaline; and one part of alkali.
In order to form a still more effective composition the foregoing ingredients
may be varied to the following proportions, viz. :-Two parts of brown grease;
two parts light pitch oil; one part of gallipoli oil or "foots" oil; one part
of fish oil or "foots" oil. These ingredients are beated together, after which
are added, one part of naphthaline, and one part of alkali.
When the ingredients are combined in the foregoing proportions the com-
pound may,
in addition to its fore-mentioned qualities, be used as a disinfectant,
a purpose for which it is also thoroughly adapted.
In lieu of using light pitch oil alone, a mixture consisting of one-half of
pitch oil, and the other half of shale or green oil may be substituted, or in
some cases, shale or green oil may be employed entirely in substitution for
the light pitch oil. The alkali which it is preferred to employ consists, one
half of sola, the other half of potash.
Having now described the nature of my said Invention, and the manner in
which the same is or may be used or practically carried into effect, I would
observe in conclusion that what I consider to be novel and original, and
therefore claim as the Invention secured to me by the herein-before in part
recited Letters Patent is,-

page_text: First, the combination of materials or substances for the production of a
dip or smear, for destroying vermin on sheep or other animals and for pre-
serving thein therefrom; substantially as herein-before described.
Second, the use of any of the substitution substances in the manufacture of
the compound, substantially as herein-before described.
In witness whereof, I, the said John Graham Hope, have hereunto set
my hand and seal, this Thirty-first day of October, One thousand eight
hundred and sixty-six.
JOHN GRAHAM HOPE. (LS.)
