IMPROVEMENTS IN PREPARING PRINTED YARNS.
Year: 1858

page_text: LETTERS PATENT to Henry Curzon, junior, of Kidderminster, for the
Invention of "IMPROVEMENTS IN PREPARING PRINTED YARNS.."
Sealed the 26th October 1858, and dated the 17th May 1858.
PROVISIONAL SPECIFICATION left by the said Henry Curzon at the
Office of the Commissioners of Patents, with his Petition, on the 17th
May 1858.
I, ENRY CURZON, junior, of Kidderminster, do hereby declare the nature
of the Invention for "IMPROVEMENTS IN PREPARING PRINTED YARNS," to be as
follows:-
These improvements relate to the process of steaming printed yarns for the
purpose of fixing the colors. Properly to understand and appreciate these
improvements it is necessary to describe the usual means heretofore employed
in conducting this process. The yarn has been laid in a wooden tray, a layer
of ont, or rice hulls, or cut straw separating it from the bottom of the tray,
an upper layer of bulls or cut straw has then been spread over it, and the
whole covered with a woven. material of cocoa-nut fibre. Several of these
trays so filled have then been loaded one above another on a suitable carriage,
moveable horizontal bars having their bearings in the frame of the carriage,
supporting each tray from pressure on the one below it. The carriage thus
loaded has then been placed in a closed chamber into which steam is introduced.
The steam naturally condenses on all the surfaces of the carriage and its

page_text: contents, and impure water is the result; it is to protect the yarn from
injurious dropping of this kind that an upper layer of hulls or cut straw and the
cocoa-nut fibre material have been employed.
its object the effectually dispensing with the
yarn, namely, the upper layer of hulls or cut
material.
Now, this Invention has for
immediate covering of the
straw and the cocoa-nut fibre
In carrying out my improvements, I cause a coarse thick material capable
of absorbing moisture, by preference of cotton or wool, to be attached to the
under side of each tray, sufficient space being allowed between the material
and the tray to which it is attached to insure ventilation, and thus to facilitate
the evaporation of that moisture which the material may have gained from
condensation of steam when the tray is removed from the steam chamber.
I dispense with the moveable horizontal bars, and furnish each tray with
elevated ends, which projecting sufficiently above the level of the yarn in
the tray support the tray abovo from pressure on it. The trays are in this
manner piled one above another on a suitable carriage, and when in the steam
chamber all steam which condenses immediately over the uncovered yarn
being absorbed by the coarse material, the yarn is protected from injurious
droppings.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Curzon in the Great Seal Patent Office on the
12th November 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
CURZON, junior, of Kidderminster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of May, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Curzon, Her special licence that I, the said IIenry Curzon,
my executors, administrators, and assigus, or such others as I, the said
Henry Curzon, 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, aud Isle of Man, an Invention for "IMPROVE-
LIENTS IN PREPARING PRINTED YARNS," upon the condition (amongst others)

page_text: that I, the said Henry Curzon, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and scals, 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 Henry Curzon, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
These improvements relate to the process of steaming printed yarns for the
purpose of fixing the colors. Properly to understand and appreciate these
improvements, it is necessary to describe the usual means heretofore employed
in conducting this process. The yarn has been laid in a wooden tray, a layer
of oat or rice hulls or cut straw separating it from the bottom of the tray, an
upper layer of hulls or cut straw has been spread over it, and the whole
covered with a woven material of cocoa-nut fibre. Several of these trays so
filled have then been loaded one above another on a suitable carriage,
moveable horizontal bars having their bearings in the frame of the carriage
supporting each tray from pressure on the one below it.. The carriage thus
loaded has then been placed in a closed chamber, into which steam is intro-
duced. The steam naturally condenses on all the surfaces of the carriage and
its contents, and impure water is the result; it is to protect the yarn from
injurious dropping of this kind that an upper layer of hulls or cut straw and
the cocoa-nut fibre material have been employed.
-
Now this Invention has for its object the effectually dispensing with the
immediate covering of the yarn, namely, the upper layer of hulls or cut straw
and the cocoa-nut fibre materials.
In carrying out my improvements, I cause a coarse thick material, capable
of absorbing moisture, by preference of cotton or wool, to be attached to the
under side of each tray, suflicient space being allowed between the material
and the tray to which it is attached, to ensure ventilation, and thus to facilitate
the evaporation of that moisture which the material may have gained from
condensation of steam when the tray is removed from the steam chamber.
I would remark that trays with perforations have been before used for a like
purpose, and they have had cloths or fabrics on their under side to catch the
color dropping through such trays. And I would state that the trays used by
me are unperforated, so that no droppings of color or other fluid can take
place through them, and the fabrics used by me are used as absorbing surfaces,

page_text: and they are at a distance from the under surfaces of the trays, so that the
space between may be ventilated. I dispense with the moveable horizontal
bars, and furnish each tray with elevated ends, which projecting sufficiently
above the level of the yarn in the tray, support the tray above from pressure
on it. The trays are in this manner piled one above another, in a suitable
carriage, and when in the steam chamber, all steam which condenses imme-
diately over the uncovered yarn being absorbed by the coarse material, the
yarn is protected from injurious droppings.
Having described my manner of carrying out my improvements, I would
have it understood that I make no claim to the mechanical parts separately;
but what I claim is the combination herein described, whereby the immediate
covering of the yarns by the upper layer of hulls or cut straw is dispensed
with; the coarse absorbing fabric used is suspended in such manner as to leave
a space on the two sides thereof for ventilation, and the trays are supported
one on the other by the raised parts of the trays without pressing on the yarns,
as explained.
In witness whereof, I, the said Henry Curzon, have hereunto set my
hand and seal, this Eleventh day of November, in the year of our
Lord One thousand eight hundred and fifty-eight.
Witness,
WM. RODEN,
of Kidderminster,
