IMPROVEMENTS IN MACHINERY FOR SIZING YARN
Year: 1871

page_text: LETTERS PATENT to Henry Harrison, of Blackburn, in the County
of Lancaster, Machine Maker and Manufacturer, for the Invention
of "IMPROVEMENTS IN MACHINERY FOR SIZING YARN."
of "IMPROVEMENTS IN MACHINERY FOR SIZING YARN."
Sealed the 19th December 1871, and dated the 7th July 1871.
PROVISIONAL SPECIFICATION left by the said Henry Harrison at the
Office of the Commissioners of Patents, with his Petition, on the
7th July 1871.
I, HENRY HARRISON, of Blackburn, in the County of Lancaster,
Machine Maker and Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MACHINERY FOR SIZING YARN," to be
as follows:-
In sizing machines of the ordinary construction it frequently happens.
that during the time the machine is stopped the size accumulates and
hardens the surface of the copper roller and
in the
upon
the warp
size trough, and that when the machine is again started the size adheres
upon

page_text: unevenly to the yarn, thereby producing bad work. Now in order to
remedy the above defect I place one or more perforated steam pipes
near the said copper roller, and when the machine is stopped the steam
is turned on, and jets of steam impinge upon the yarn near where it is
1ressed by the rollers, thereby preventing the size adhering to the
surface of the copper roller or baking upon the warp.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Harrison in the Great Seal Patent Office
on the 4th January 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
HARRISON, of Blackburn, in the County of Lancaster, Machine Maker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of July, in the year
of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Henry Harrison, Her special
licence that I, the said Henry Harrison, my executors, administrators,
and assigns, or such others as I, the said Henry Harrison, my cxc-
cutors, 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 "IMPROVEMENTS
IN MACHINERY FOR SIZING YARN," upon the condition (amongst others)
that I, the said Henry Harrison, my executors 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 Henry Harrison, do hereby declare
the nature of my said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by
the following statement (that is to say):
In sizing machines of the ordinary construction it frequently happens
that during the time the machine is stopped the size accumulates and
hardens upon the surface of the copper rollers, and upon the warp in the
size trough, and that when the machine is again started the size adheres
unevenly to the yarn, thereby producing bad work. Now in order to
remedy the above defect, I place one or more perforated steam pipes
near the said copper rollers, and when the machine is stopped the steam
is turned on, and jets of steam impinge upon the yarn near where it is
pressed by the rollers, thereby preventing the size adhering to the
surface of the copper rollers or baking upon the warp.
And in order that my Invention may be fully understood, I will
proceed to describe the accompanying Drawing, which represents in
section part of an ordinary sizing machine to which my improvements
are applied.
a is the size trough; b, the guide rollers; c, the immersion roller;
d, d', the copper rollers; and e, e', the top rollers, all of which are made
in the usual manner; f is a perforated pipe placed near the nip of the
rollers d and e, and g, h, are two other perforated pipes near the nip of
the rollers and e¹. These three perforated pipes are supplied with
steam by the pipe i, which is connected to the ordinary steam pipe j,
and there is a tap k applied between the ends of the pipes i and j to
shut the steam from the pipe i when required. The tap k is connected
to the starting lever by the forked rod m.
The mode of operation is as follows:-So long as the yarn is passing
through the size trough the tap is closed to shut the steam out of the
perforated pipes f, g, and h; but as soon as the starting lever is moved
by the attendant to stop the machine, the forked rod m acting on the
lever fixed to the plug of the tap k opens the said tap sufficiently to
admit steam to the pipes f, g, and h, thereby causing jets of steam to
impinge upon the rollers and the yarn, which keep the size soft and
prevent the accumulation thereof on the rollers and on the yarn.
Having thus stated the nature of my Invention, and described a
convenient mode of performing the same, I wish it to be understood
that I do not intend to limit myself to the details given; but that I

page_text: claim the application of jets of steam to the rollers and yarn in sizing
machines for the purposes described.
In witness whereof, I, the said Henry Harrison, have hereto set
my hand and seal, this Second day of January, One thousand
cight hundred and seventy-two.
HENRY HARRISON. (L.S.)
