Year: 1873

page_text: LETTERS PATENT to Thomas Holliday, Charles Holliday, and Edgar
Holliday, all of Huddersfield, in the County of York, Manufacturing
Chemists, for the Invention of "IMPROVEMENTS IN MEANS OR APPARATUS
TO FACILITATE THE DYEING OF WOOL, HAIR, OR OTHER FIBRE BY THE USE
OF INDIGO AND CERTAIN HYDROSULPHITES."
Sealed the 14th April 1874, and dated the 21st October 1873.
PROVISIONAL SPECIFICATION left by the said Thomas Holliday,
Charles Holliday, and Edgar Holliday at the Office of the Com-
missioners of Patents, with their Petition, on the 21st October
1873.
We, THOMAS HOLLIDAY, CHARLES HOLLIDAY, and EDGAR HOLLIDAY,
all of Huddersfield, in the County of York, Manufacturing Chemists, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MEANS OR APPARATUS TO FACILITATE THE DYEING OF WOOL, HAIR, OR OTHER FIBRE
BY THE USE OF INDIGO AND CERTAIN HYDROSULPHITES," to be as follows:-
The object of the Invention is to facilitate the dyeing of wool, hair, or
other raw fibre when using indigo and certain hydrosulphites of the
character described in the Specification of Letters Patent granted to Paul
Schützenberger and Felix de Lalande, dated December 13th 1871, No.

page_text: 3377, in order that such die may be caused thoroughly to saturate or be
incorporated with such fibre. For this purpose we cause the fibre to be
thoroughly agitated in and carried forward through the vat or receptacle
for the dye by means of rakes, forks, or other such like agitating and
progressively moving means; and to prevent the fibre after immersion in
the dye liquid from rising to the surface thereof, so as to be acted upon
injuriously by the atmosphere before complete saturation, we apply bars
or grates or such like guides placed below, but parallel with the surface
of the die liquid to guide the fibre in its progress, and keep it below the
surface of the liquid until the dye has had time to act on the fibre to the
extent desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Holliday, Charles Holliday, and Edgar
Holliday in the Great Seal Patent Office on the 20th April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS

within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MEANS OR

page_text: writing under our or their hands and seals, or under the hand and
seal of one of us or them, 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

NOW KNOW YE, that we, the said Edgar Holliday, & Charles
Holliday, on behalf of ourselves and the said Thomas Holliday, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say:
The object of the Invention is to facilitate the dyeing of wool, hair, or
other raw fibre when using indigo and certain hydrosulphites of the
character described in the Specification of Letters Patent granted to
Paul Schützenberger and Felix de Lalande, dated December 13th 1871,
No. 3377, in order that such dye may be caused thoroughly to saturate
or be incorporated with such fibre. For this purpose we cause the fibre
to be thoroughly agitated in and carried forward through the vat or re-
ceptacle for the dye by means of rakes, forks, or other such like agitating
and progressively moving means, and to prevent the fibre after immer-
sion in the dye liquid from rising to the surface thereof, so as to be
acted upon injuriously by the atmosphere, before complete saturation we
apply bars or grates or such like guides placed below, but parallel with
the surface of the dye liquid to guide the fibre in its progress, and keep
it below the surface of the liquid until the dye has had time to act on
the fibre to the extent desired.
In witness whereof, we, the said Edgar Holliday and Charles
Holliday, have hereunto set our hands and seals, this Eighteenth
day of April, in the year of our Lord One thousand eight
hundred and seventy-four.
