IMPROVEMENTS IN AWWA Benang
Year: 1867

page_text: LETTERS PATENT to Read Holliday, of Huddersfield, in the County of
York, Manufacturing Chemist, for the Invention of "IMPROVEMENTS IN
AWWA Benang "
Sealed the 8th May 1868, and dated the 16th November 1867.
PROVISIONAL SPECIFICATION left by the said Read Holliday at the
Office of the Commissioners of Patents, with his Petition, on the 16th
November 1867.
I, READ HOLLIDAY, of Huddersfield, in the County of York, Manufacturing
Chemist, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN CLEANSING WOOL AND OTHER SIMILAR ANIMAL FIBRES," to be as
follows:-
The Invention relates to the use of hydrocarbon liquors, such as the
distillates of coal tar, petroleum, and paraffin, schist, or shale oils, in the
cleansing of wool and other animal fibres.
In carrying out my improvements I (according to one method) place the
fibre to be operated upon in a close vessel supplied with the liquid bydro-
carbon, (by preference coal tar, naptha, or petroleum spirit,) and when the
fibre has become saturated with the liquid hydrocarbon I allow such liquid to
flow from it into a still. I then allow steam under pressure to flow through
the still and through the vessel containing the fibre, and through such fibre
into a condenser for recovery. After continuing the operation for some time

page_text: in proportion to the tar, grease, and dirt contained in the wool and other
fibre I shut off the hydrocarbon, but continue the steam through the fibre and
condenser till all the hydrocarbon is brought over and recovered. The effect
of the hydrocarbon liquid and vapour on the fibre is to loosen the tar, paint,
grease, and matters adhering to it, so as to facilitate the subsequent removal
(if found necessary) with water or other wash liquor. By these means wool
and other fibres that have hitherto been of little value in consequence of the
difficulty in removing the tar, paint, and dirt adhering thereto are made
available, and great economy of working is effected.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Read Holliday in the Great Seal Patent Office on the
14th May 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, READ
HOLLIDAY, of Huddersfield, in the County of York, Manufacturing Chemist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of November, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Read Holliday, Her special licence that I, the said Read
Holliday, my executors, administrators, and assigns, or such others as 1,
the said Read Holliday, my executors, administrators, and 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 "IMPROVE-
MENTS IN CLEANSING WOOL AND OTHER SIMILAR ANIMAL FIBRES," upon the con-
dition (amongst others) that I, the said Read Holliday, 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 Read Holliday, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
The Invention relates to the use of hydrocarbon liquors, such as the
distillates of coal tar, petroleum, and paraffin, schist, or shale oils, in the
cleansing of wool and other animal fibres.
In carrying out my improvements I (according to one method) place the
fibre to be operated upon in a close vessel supplied with the liquid hydro-
carbon, (by preference coal tar, naptha, or petroleum spirit,) and when the
fibre has become saturated with the liquid hydrocarbon I allow such liquid to
flow from it into a still. I then allow steam under pressure to flow through
the still and through the vessel containing the fibre, and through such fibre
into a condenser for recovery. After continuing the operation for some time
in proportion to the tar, grease, and dirt contained in the wool and other fibre
I shut off the hydrocarbon, but continue the steam through the fibre and con-
denser till all the hydrocarbon is brought over and recovered. The effect
of the hydrocarbon liquid and vapour on the fibre is to loosen the tar,
paint, grease, and matters adhering to it, so as to facilitate the subsequent
removal (if found necessary) with water or other wash liquor. By these
means wool and other fibres that have hitherto been of little value in con-
sequence of the difficulty in removing the tar, paint, and dirt adhering thereto
are made available, and economy of working is effected.
In witness whereof, I, the said Read Holliday, have hereunto set my
hand and seal, this Eighth day of May, in the year of our Lord One
thousand eight hundred and sixty-eight.
READ HOLLIDAY. (L.B.)
