page_text: LETTERS PATENT to Thomas Holliday, Charles Holliday, and Edgar
Holliday, all of Huddersfield, in the County of York, Manu-
facturing Chemists, for the Invention of "IMPROVEMENTS IN MEANS OR
APPARATUS TO FACILITATE THE DYEING OF FABRICS AND THREAD OR YARNS
DV MOTO OF TYPICA
CUMAYY "
'
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 FABRICS AND THREAD
OR YARNS BY THE USE OF INDIGO AND CERTAIN HYDROSULPRITES," to be as
follows:-
The improvements relate to means or apparatus by which to facilitate
the dyeing of fabrics and thread or yarns when using indigo and certain

page_text: 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 to facilitate the penetration of
such dyeing matters into the fabric, thread, or yarn, and the consequent
uniformity of the effect obtained. For this purpose we employ two sets
of rollers carried by and so as to revolve in a frame by which the rollers
are placed in or removed from the vat or receptacle for the dye. One
set of these rollers when in the vat is suspended some distance below the
surface of the liquid therein; the other set is suspended as near as
possible to the bottom of the vat or receptacle for the dye liquid.
The fabric, thread, or yarn to be dyed is conducted down under one of
the lower rollers in the vat, thence up over one of the upper ones down
under the next lower one, up over the next upper one, and so on
alternately under and over the respective rollers until it passes out of
the vat, when it is first conducted between a pair of squeezing rollers,
and is there conducted over and under other rollers in positions to admit
of the free action of the air on the dyed fabric, thread, or yarn, and it is
then folded by ordinary folding means.
The upper rollers are kept sufficiently below the surface of the dye
liquid in the vat to prevent the action of atmospheric air on the fabric,
thread, or yarn, until the dyeing is accomplished, whilst the lower
rollers are applied near the bottom of the vat to insure the more
complete action of the liquid on the fabric, thread, or yarn.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Holliday, Charles Holliday, and Edgar 2
Holliday, in the Great Seal Patent Office on the 20th April
1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
HOLLIDAY, CHARLES HOLLIDAY, and EDGAR HOLLIDAY, all of
Huddersfield, in the County of York, Manufacturing Chemists, send a
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of October, in the year
of our Lord One thousand eight hundred and seventy-three, in the

page_text: thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Thomas Holliday, Charles.
Holliday, and Edgar Holliday, Her special license that we, the said
Thomas Holliday, Charles Holliday, and Edgar Holliday, our executors,
administrators, and assigns, or such others as we, the said Thomas
Holliday, Charles Holliday, and Edgar Holliday, our executors, adminis-
trators, 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 "IMPROVEMENTS IN MEANS OR
APPARATUS TO FACILITATE THE DYEING OF FABRICS AND THREAD OR YARNS BY THE
USE OF INDIGO AND CERTAIN HYDROSULPHITES," upon the condition (amongst
others), that we, the said Thomas Holliday, Charles Holliday, and
Edgar Holliday, our executors or administrators, by an instrument in
-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
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said Edgar Holliday and 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 improvements relate to means or apparatus by which to facilitato
the dyeing of fabrics and thread or yarns 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 to facilitate the penetration of
such dyeing matters into the fabric, thread, or yarn, and the consequent
uniformity of the effect obtained. For this purpose we employ two sets
of rollers carried by and so as to revolve in a frame by which the rollers
are placed in or removed from the vat or receptacle for the dye. One
set of these rollers when in the vat is suspended some distance below
the surface of the liquid therein; the other set is suspended as near as
possible to the bottom of the vat or receptacle for the dye liquid.
