IMPROVEMENTS IN THE MEANS EMPLOYED WHEN STEAMING PRINTED YARNS.
Year: 1859

page_text: LETTERS PATENT to Joseph Crossley, of Halifax, for the Invention of
"IMPROVEMENTS IN THE MEANS EMPLOYED WHEN STEAMING PRINTED YARNS.".
PROVISIONAL SPECIFICATION left by the said Joseph Crossley at the
Office of the Commissioners of Patents, with his Petition, on the 9th
February 1859.
I, JOSEPH CROSSLEY, of Halifax, do hereby declare the nature of the Inven-
tion for "IMPROVEMENTS IN THE MEANS EMPLOYED WHEN STEAMING PRINTED
YARNS," to be as follows:-
When steaming printed yarns, such are laid into cradles, trays, or other
suitable supports placed one above another within a chamber capable of being
opened for the removal of one lot of yarns after the same has undergone the
process of steaming, and closed again after another lot of yarns has been
placed within the chamber.
According to one part of a Patent granted to myself in conjunction with
James Bolton, No. 1952, and dated the 21st of August 1856, zinc or metal
plates placed between the supports to the yarns are employed for the purpose
of catching and thereby preventing the droppings of the colors of one set of
yarns from falling into and mixing with the colors of the yarns below, and it
is to the zinc or metal plates here named that this part of the present improve-
Considerable difficulty has been experienced hitherto, owing to
the quantity of cold air which passes into the steam box or chamber when the
same is opened for the removal of the yarn just acted upon, so that when a
new lot of yarns has been introduced within the chamber, and the latter is

page_text: again closed, a great part of the steam which is at first admitted therein is
condensed into water, which gathers underneath the zinc or metal plates
before named, and drops into the yarns next below, the water being more or
less charged with the metallic substance received from. the plates stains
the yarns.
The first part then of my present improvements is to obviate this difficulty,
by preventing the condensation of the steam underneath the zinc or metal
plates; and for this purpose these plates are so formed as to admit of the
introduction into the inside thereof of steam or other heating media, which
serves to keep the plates constantly hot, and so prevent the possibility of
condensed steam gathering underneath the plates, and thereby dropping into
the yarns below.
My improvements also consist when steaming printed yarns in the employ-
ment of troughs placed underneath the cradles or other supporting means to
the yarns, such troughs containing water heated to a great degree by any
suitable means, and the steam arising from the hot water passes at once
through the yarn placed immediately above it, thus fixing the colors of the
yarn, and the steam then passes away out at the top of the chamber (which in
this case is sufficiently open), and carries away with it the impure gases arising
from the coloring matter. This part of my improvements is also applicable
when only one trough and cradle or other supporting means to the yarns is
employed.
Also my improvements relate to constructing the outer framework of the
cradle frames or other supporting means to the yarns of cast or wrought iron,
instead as heretofore of wood, thereby effecting a great saving in wear and
tear.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Joseph Crossley in the Great Seal Patent Office on the
5th August 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
CROSSLEY, of Halifax, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of February, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Joseph Crossley, Her special licence that I, the said

page_text: Joseph Crossley, my executors, administrators, and assigns, or such others as
I, the said Joseph Crossley, 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 THE MEANS EMPLOYED WHEN STEAMING PRINTED YARNS," upon the
condition (amongst others) that I, the said Joseph Crossley, my executors
or administrators, by an instrument in writing under my, or their, or one of
their bands 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 Joseph Crossley, 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 fol-
lowing statement thereof, that is to say :-
When steaming printed yarns, such are laid into cradles, trays, or other
suitable supports placed one above another within a chamber capable of being
opened for the removal of one lot of yarns after the same has undergone the
process of steaming, and closed again after another lot of yarns has been
placed within the chamber.
According to one part of a Patent, granted to myself in conjunction with
James Bolton, No. 1952, and dated the 21st of August 1856, zinc or metal
plates placed between the supports to the yarns are employed, for the purpose
of catching, and thereby preventing the droppings of the colors of one set of
yarns from falling into and mixing with the colors of the yarns below, and it
is to the zinc or metal plates here named that this part of the present
improvements refer. Considerable difficulty has been experienced hitherto,
owing to the quantity of cold air which passes into the steam box or chamber
when the same is opened for the removal of the yarn just acted upon, so that
when a new lot of yarns has been introduced within the chamber, and the
latter is again closed, a great part of the steam which is at first admitted
therein is condensed into water, which gathers underneath the zinc or metal
plates before named, and drops into the yarns next below, and the water being
more or less charged with the metallic substance received from the plates
stains the yarns.
The first part then of my present improvements is to obviate this difficulty

page_text: by preventing the condensation of the steam underneath the zinc or metal
plates; and for this purpose these plates are so formed as to admit of the
introduction into the inside thereof of steam or other heating media, which
serves to keep the plates constantly hot, and so prevent the possibility of con-
densed steam gathering underneath the plates, and thereby dropping into the
yarns below. These plates may either be made of cast iron, having the
channels or passages for the circulation of the heating media cast therein, or
two plates may be rivetted together so as to form one hollow plate. I do not,
however, confine myself to any precise description of plate.
My improvements also consist when steaming printed yarn in the employ-
ment of troughs placed underneath the cradles or other supporting means to the
yarns, such troughs containing water heated to a great degree by any suitable
means, and the steam arising from the hot water passes at once through the
yarn placed on trays immediately above it, thus fixing the colors of the yarn,
and the steam then passes away out at the top of the chamber (which in this
case is sufficiently open), and carries away with it the impure gases arising
from the coloring matter. This part of my improvements is also applicable
when only one trough and cradle or other supporting means to the yarns is
employed at each steaming.
Also my improvements relate to constructing the whole or part of the outer
framework of the cradle frames or other supporting means to the yarns of
cast or wrought-iron, instead as heretofore of wood, thereby effecting a great
saving in wear and tear.
In witness whereof, I, the said Joseph Crossley, have hereunto set
my hand and seal, this Third day of August, in the year of our Lord
One thousand eight hundred and fifty-nine.
JOSEPH CROSSLEY. (L.S.)

said Joseph Crossley, in the presence

in England.
