IMPROVEMENTS IN APPARATUS FOR STEAMING TEXTILE FABRICS AND YARNS OR WARPS
Year: 1875

page_text: LETTERS PATENT to William Holt, of Halifax, in the County of
York, Dyer and Finisher, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR STEAMING TEXTILE FABRICS AND YARNS OR WARPS."
Sealed the 7th April 1876, and dated the 9th October 1875.
PROVISIONAL SPECIFICATION left by the said William Holt at the
Office of the Commissioners of Patents, with his Petition, on the
9th October 1875.
I, WILLIAM HOLT, of Halifax, in the County of York, Dyer and
Finisher, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN APPARATUS FOR STEAMING TEXTILE FABRICS AND YARNS OR
WARPS," to be as follows:-
This Invention consists in the construction and use of two perforated
cylinders combined in one concentrically within the other, so that steam
may first be introduced to the inner cylinder and, pass through the
perforations thereof to the outer cylinder and thence through the
perforations in the periphery thereof to the fabrics, yarns, or warps
which are to be wound thereon to be steamed.

page_text: By this Invention the pressure of the steam is reduced in passing
through the first perforations without reducing its heat, and steam is
thereby economized.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Holt in the Great Seal Patent Office on
the 8th April 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HOLT, of Halifax, in the County of York, Dyer and Finisher, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of October, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Holt, Her special licence,
that I, the said William Holt, my executors, administrators, and
assigns, or such others as I, the said William Holt, 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 Ircland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS FOR STEAMING TEXTILE FABRICS AND YARNS OR WARPS," upon the
condition (amongst others) that I, the said William Holt, my exccutors
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 William Holt, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and accompanying Sheet of Drawings (that is to
say):

page_text: This Invention consists in the construction and use of two perforated
cylinders combined in one concentrically, that is to say, one cylinder is
placed concentrically within the other so that steam may first be intro-
duced to the inner cylinder and pass through the perforations thereof to
the outer cylinder and thence through the perforations in the periphery
thereof to the fabrics, yarns, or warps which are to be wound thereon to
be steamed.
By this Invention the pressure of the steam is reduced in passing
through the first perforations without reducing its heat, and steam is
thereby economized.
In the accompanying Sheet of Drawings A represents the outer
cylinder and B the inner one (shewn in dotted lines). These cylinders
are mounted and capable of revolving in the outer casing or chamber C,
the top part c¹ of which is moveable so as to allow of the piece or fabric
being wound upon the cylinder A, after which the pressing roller D is
lifted out of the way, the position being shewn in dotted lines, and the
top of the outer casing lowered and fastened by bolts and "cotters."
Steam is then allowed to pass through the pipe E to the inner cylinder
through the perforations thereof to the outer one, and through that to
the fabric, collecting finally in the outer casing. The difference in
pressure of the steam in the inner cylinder from that in the outer casing
is indicated by the pressure gauges F and G, one of which communicates
with the inner cylinder and the other with the casing.
The arrangement of steam pipes and valves is such that the fabric
may be steamed from the outer casing inwards if desirable, in which
case the steam passes off by the pipe H. The cylinders A and B are
caused to rotate by pullies on the axis thereof, whilst the operations of
the other parts of the machine will be well understood on reference to
the Drawing.
In witness whereof, I, the said William Holt, have hereunto set
my hand and seal, this Seventh day of April, in the year of our
Lord One thousand eight hundred and seventy-six.
WILLIAM HOLT. (L.S.)
