CERTAIN IMPROVEMENTS IN OR APPLICABLE TO SIZING AND DRESSING MACHINES
Year: 1867

page_text: LETTERS PATENT to William Scowcroft Lowe, of New Mills, in the County
of Derby, Cotton Spinner and Manufacturer, for the Invention of
"CERTAIN IMPROVEMENTS IN OR APPLICABLE TO SIZING AND DRESSING
MACHINES."
Sealed the 13th August 1867, and dated the 9th March 1867.
PROVISIONAL SPECIFICATION left by the said William Scowcroft Lowe at
the Office of the Commissioners of Patents, with his Petition, on the
9th March 1867.
I, WILLIAM SCOWCROFT LOWE, of New Mills, in the County of Derby,
Cotton Spinner and Manufacturer, do hereby declare the nature of the said
Invention for "CERTAIN IMPROVEMENTS IN OR APPLICABLE TO SIZING AND
DRESSING MACHINES," to be as follows:-
My Invention is particularly applicable to the machines for sizing and dressing
warps known as "tape legs" or "slashers," but it may be applied to machines
for sizing and dressing yarn in the bank, or other machines in which a size
trough or box is employed. And it consists in the application of a self-acting tap
or valve with a ball or float to the size trough, by which fresh size is admitted
in proportion to the quantity taken up by the yarn, and the size is kept at the
same level in the trough; the ball tap is applied in a box connected to the
size trough, or the float may be in the size trough and act by a rod on the

page_text: lever of the tap through which the size enters. By this means the size is
always kept at a uniform strength, and the attendant is relieved from the duty
of occasionally allowing the size to run into the trough, and is therefore at
lever of the tap through which the size enters. By this means the size is
always kept at a uniform strength, and the attendant is relieved from the duty
of occasionally allowing the size to run into the trough, and is therefore at
liberty to devote his whole time to the requirements of the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Scowcroft Lowe in the Great Seal Patent Office on
the 6th September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
SCOW CROFT LOWE, of New Mills, in the County of Derby, Cotton Spinner and
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of March, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Scowcroft Lowe, Her special license that I, the said William Scoweroft
Lowe, my executors, administrators, and assigns, or such others as 1, the
said William Scowcroft Lowe, 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 "CERTAIN
IMPROVEMENTS IN OR APPLICABLE TO SIZING AND DRESSING MACHINES," upon the
condition (amongst others) that I, the said William Scowcroft Lowe, 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 per-
formed, 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 Scowcroft Lowe, 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, (that is to say):-
My Invention is particularly applicable to the machines for sizing and
dressing warps known as "tape legs" slashers," and the ordinary or common
sizing machine, but it may be applied to machines for sizing and dressing
yarn in the hank, or other machines in which a size trough or box is employed,

page_text: and it consists in the application of a self-acting acting tap or valve with a
ball or float to the size trough by which fresh size is admitted in proportion
to the quantity taken up by the yarn, and the size is kept at the same level in
the trough; the ball and tap is applied in a box attached to the size trough, or
the float may be placed in the size trough and connected by a rod to the lever
of the tap through which the size enters. By this means the size is always
kept at a uniform strength and the attendant is relieved from the duty of
occasionally allowing the size to run into the trough, and is therefore at liberty
to devote his whole time to the other requirements of the machine.
And in order that my Invention may be fully understood and readily carried
into operation, I will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Figure 1 represents in elevation part of an ordinary sizing and dressing
machine to which my improvements are applied; Figure 2 is a side view, and
Figure 3 a plan of the same.
a is the the size trough, which is provided as usual, with a roller under
which the yarn passes, and b¹ is a box or vessel connected to the trough a, and
communicating with it through the orifice c. The size for supplying the
trough a is conveyed from the pan in which it is boiled and prepared, through
the pipe d, and passes through the tape into the box 6, from which it flows
into the trough a; the plug of the tape is provided with a lever f and ball g,
which floats on the size. When the level of the size in the box 6 and trough a
is lowered, the bali g lowers also, and turns on more size, and when the level
rises the ball g in rising shuts off the size. By this means the fresh size is
admitted in proportion to the quantity taken up by the yarn, and the size is
thereby kept at or nearly at a uniform strength, and at the same or nearly the
same level, consequently a uniform length of yarn is at all times immersed in
the trough. The pipe is to admit steam to keep the size boiling in the box b
and the end of the lever f projecting beyond the box is to enable the attendant
to close the valve or tape when the machine is stopped. By means of the
self-acting tap or valve above described, the workman is relieved from the
duty of attending to the tap to allow the size to run into the trough, and is
therefore at liberty to devote his whole time to the other requirements of the
machine.
It is evident that my Invention may be modified by applying the float in the
size trough and connecting it by a rod and lever to the tap or valve through
which the size passes.
Having thus stated the nature of my Invention, and described a convenient
mode of carrying the same into operation, I wish to remark that I do not

page_text: intend to limit myself to the details given; but that what I claim is, the
application of a self-acting valve or tap to the size troughs of machines used
in sizing and dressing for regulating the supply of size according to the
quantity used.
In witness whereof, I, the said William Scowcroft Lowe, have hereto set
my hand and seal, this Third day of September, One thousand eight
hundred and sixty-seven.
WILLIAM SCOWCROFT LOWE. (L.S.)
