Year: 1873

page_text: LETTERS PATENT to Michael Wheelwright Ivison, of Glasgow, in the
County of Lanark, North Britain, Civil Engineer, for the In-
vention of "AN IMPROVED SHEEP DIP, WHICH IS ALSO APPLICABLE TO
ANIMALS OTHER THAN SHEEP."
Scaled the 23rd September 1873, and dated the 17th April 1873.
PROVISIONAL SPECIFICATION left by the said Michael Wheelwright
Ivison at the Office of the Commissioners of Patents, with his
Petition, on the 17th April 1873.
I, MICHAEL' Wheelwright IVISON, of Glasgow, in the County of
Lanark, North Britain, Civil Engineer, do hereby declare the nature of
the said Invention of "AN IMPROVED SHEEP DIP, WHICH IS ALSO APPLICABLE
TO ANIMALS OTHER THAN SHEEP," to be as follows, that is to say:
--
This Invention, which relates to an improved dip for sheep, and which
is also applicable to other animals, consists in a compound or mixture of
green gas oil (procured by destructive distillation of paraffin) with palm
oil or other greasy or fatty substance, and caustic soda, caustic potash,
water, and glue.

page_text: The proportions of these ingredients may be considerably varied,
according to the circumstances under which the dip is to be employed,
but the following proportions give good results, namely, of green gas oil
200 parts by weight; of palm oil or other grease, 100 parts; of caustic
soda, 15 parts; of caustic potash, 15 parts; of water, 100 parts, and of
glue, 12 parts.
In manufacturing the dip the caustic soda, caustic potash, and glue
.are boiled in water till completely saponified, after which the palm oil or
other grease is added and stirred into the mixture until amalgamated
therewith, then the green gas oil is added and amalgamated with the
other ingredients, the temperature of the boiler or vessel being previously
allowed to cool down somewhat. After the dip has been thus com-
pounded it is allowed to cool down until it becomes plastic or viscous,
after which it is placed in tins or other suitable vessels.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Michael Wheelwright Ivison in the Great Seal
Patent Office on the 16th October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MICHAEL -
WHEELWRIGHT IVISON, of Glasgow, in the County of Lanark, North
Britain, Civil Engincer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of April, in the year.
of our Lord One thousand eight hundred and seventy-three, in the
36th year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Michael Wheelwright Ivison, Her special
license that I, the said Michael Wheelright Ivison, my executors,
administrators, and assigns, or such others as I, the said Michael
Wheelwright Ivison, 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 for "AN IMPROVED SHEEP DIP, WHICH IS ALSO
APPLICABLE TO ANIMALS OTHER THAN SHEEP," upon the condition (amongst

page_text: others) that I, the said Michael Wheelwright Ivison, by an instrument
in writing under my 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
5 Great Seal Patent Office within six calendar months, next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Michael Wheelwright Ivison, 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
0 in and by the following statement, that is to say:-
My said Invention, which relates to an improved dip for sheep, and
which is also applicable to other animals, consists in a compound or
mixture of green gas oil (procured by destructive distillation of paraffin)
with palm oil or other greasy. or fatty substances, and caustic soda,
5 caustic potash, water, and glue.
The proportions of these ingredients may be considerably varied;
according to the circumstances under which the dip is to be employed,
but the following proportions give good results, namely, of green gas
oil, 200 parts by weight; of palm oil, or fish oil, or tallow, or lard,
or other suitable grease, 100 parts; of caustic soda, 15 parts; of caustic
potash, 15 parts; of water, 100, and of glue 12 parts.
In manufacturing the dip the caustic soda, caustic potash, and gluc
are boiled in water till completely saponified, after which the palm oil
or other grease is added and stirred into the mixture until amalgamated™
therewith. The mixture is then allowed to cool down to about 160°
Fahrenheit, after which the green gas oil is added and amalgamated with
the other ingredients. After the dip has been thus compounded it is
allowed to cool down until it becomes plastic or viscous, after which it
is placed in tins or other suitable vessels.
In using the dip it is dissolved in hot water, which being effected,
cold water is added and the whole stirred or agitated until the liquid
presents a creamy appearance or consistency. Into the solution so
prepared the sheep, which should be dry before dipping, is immersed in
such a manner as to allow the solution to penetrate through the wool to
tho skin.

page_text: In order to keep the bath of an uniform strength 5 pounds of the dip
composed as herein-before described should be added to the solution after
every every 25 sheep are dressed.
Good proportions of the compound herein-before described to employ
are, for "dipping," 1 pound of the dip dissolved in 5 gallons of water
for every 5 sheep; for "pouring," 1 pound of the dip dissolved in
1 gallon of water for every 5 sheep; for "scab," 1 pound of the dip
dissolved in 2 gallons of water for 5 sheep; or, in the case of scab, the
part affected may be rubbed with the compound as an ointment; for
"smearing," 1 pound of the dip dissolved in 1 pint of oil is employed 1
for every three sheep. It is to be understood that these proportions
may be varied for the different operations herein-before set forth.
Having now described and particularly ascertained the nature of my
said Invention, and the system, mode, or manner in or under 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 there-
fore claim as the Invention secured to me by the herein-before in part
recited Letters Patent is, the combination of green gas oil with the other
substances herein-before described constituting a dip for sheep or other
animals.
In witness whereof, I, the said Michael Wheelwright Ivison, have
hercunto set my hand and seal, this Fifteenth day of October
One thousand eight hundred and seventy-three.
MICHAEL WHEELWRIGHT IVISON. (L.S.)
