IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR SIZING AND DRESSING YARN
Year: 1877

page_text: LETTERS PATENT to Lewis Haslam, of Bolton, in the County of Lancaster, for
the Invention of "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR
SIZING AND DRESSING YARN."
Sealed the 18th January 1878, and dated the 17th November 1877.
PROVISIONAL SPECIFICATION left by the said Lewis Haslam at the Office
of the Commissioners of Patents on the 17th November 1877.
LEWIS HASLAM, of Bolton, in the County of Lancaster. "IMPROVEMENTS IN
THE METHOD OF AND APPARATUS FOR SIZING AND DRESSING YARNS."
This Invention is intended, principally, to be applied to the sizing and dressing
of fine yarns, but it may also be used with advantage in dressing other kinds of
yarn, the object of my Invention being to prevent the yarn from adhering together
during the process, and having to be separated after drying, which (especially in
finer counts of yarn) is apt to break or otherwise injure the yarn.
According to the ordinary process and apparatus the contents of about six yarn
beams are all passed together in a single sheet or layer through the size, and
continue in that form until after they are dried, when the threads are found to be
in a state of more or less adhesion, and require to be separated.
My Invention consists, principally, in dividing the contents of each yarn beam
into a separate and distinct layer as soon as they leave the sizing trough, and in
retaining them thus in separate layers until they are dry, whereby their adhesion is
entirely prevented, and the sizing and dressing of fine yarns can be carried on quite
as rapidly as coarser yarns are now dressed by the machine called the "slasher."
After the yarn has passed from the sizing trough and through the squeezing
rollers it passes into a drying chamber, where the contents of each yarn beam is
passed over a separate roller or bar, and thence past the steam drying boxes to the
other end of the drying chamber, and over other separate rollers, and then out
through the other end of the chamber. By this time the yarn is sufficiently dry

through the remainder of the process together.
"
The yarn may, if preferred, be further divided into separate threads by passing a
lease rod" through the same at the back of each of the first set of dividing
rollers.
Another advantage obtained by the use of this improved method and apparatus
is that the space left between the threads being greater there is more room for the
circulation of the hot air, and hence the drying process is accelerated.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Lewis Haslam in the Great Seal Patent Office on the 17th May
1878.
LEWIS HASLAM, of Bolton, in the County of Lancaster. "IMPROVEMENTS IN
THE METHOD OF AND APPARATUS FOR SIZING AND DRESSING YARN."
This Invention is intended, principally, to be applied to the sizing and dressing
of fine yarns, but it may also be used with advantage in dressing other kinds of
yarn, the object of the Invention being to prevent the yarn from adhering together
during the process, and having to be separated after drying, which (especially in
the finer counts of yarn) is apt to break or otherwise injure the yarn.
According to the ordinary process and apparatus the contents of about six yarn
beams are all passed through the size, and continue in that form until after they are
dried, when the threads are found to be in a state of more or less adhesion, and
require to be separated.
My Invention consists, principally, in dividing the contents of each yarn beam
into a separate and distinct layer as soon as they leave the sizing, and retaining
them thus in separate layers until they are dry, whereby their adhesion is entirely
prevented, and the sizing and dressing of fine yarns can be carried on quite as
rapidly as coarser yarns are now dressed by the machine called the "slasher."
The annexed Drawing illustrates in longitudinal section the construction of my
improved apparatus.
After the yarn has passed from the sizing trough a, a, and over the brush b, b, it
passes into a drying chamber, where it passes under a roller c, and the contents of
each yarn beam is passed over a separate roller, rod, or bar c, d, and thence past
the steam drying boxes e, e, to the other end of the drying chamber, and either over
other similar separate rollers or under a single roller f, f, shown in the Drawing,
and then out through the other end of the chamber. The said rollers, rods, or
bars d, d, are (by preference) so arranged that each layer of yarn touches two rods
or bars, one above and one below. The distance between the rollers, rods, or bars
d, d, and the roller f (and consequently the length of the steam drying boxes e, e,)
may be varied, but for ordinary purposes it is found that a length of about twelve
feet is sufficient for the yarn to traverse between the two points. By this time the
yarn is sufficiently dry not to adhere, and the whole six layers can now be united
in one sheet, and pass on through the remainder of the process together.

page_text: The yarn may, if preferred, be further divided into separate threads by passing a
"lease rod" through the same at the back of each of the first set of dividing
rollers.
Another advantage obtained by the use of this improved method and apparatus
is, that the space left between the threads being greater there is more room for the
circulation of the hot air, and hence the drying process is accelerated.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I wish it to be understood that I claim as my Invention,-
Firstly. Dividing the contents of the yarn beams into separate and distinct
layers as soon as, or soon after, they leave the sizing trough, and retaining them
thus in separate layers until they are dry, or nearly so, substantially in the manner
and for the purpose herein-before set forth.
Secondly. The use and arrangement of rollers, bars, or rods e, e, or their equivalent,
in different planes for such purpose, substantially as described, and illustrated by
the annexed Drawing.
In witness whereof, I, the said Lewis Haslam, have bereunto set my hand
and seal, this Fourteenth day of May, in the year of our Lord One thousand
eight hundred and seventy-eight.
L. HASLAM. (L.S.)
