IMPROVEMENTS IN MACHINERY FOR SHAKING AND STRAIGHTENING YARN
Year: 1878

page_text: LETTERS PATENT to Samuel Knowles, of Tottington, near Bury, in the County
of Lancaster, Yarn Bleacher, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR SHAKING AND STRAIGHTENING YARN."
Sealed the 23rd May 1879, and dated the 5th December 1878.
PROVISIONAL SPECIFICATION left by the said Samuel Knowles at the
Office of the Commissioners of Patents on the 5th December 1878.
SAMUEL KNOWLES, of Tottington, near Bury, in the County of Lancaster, Yarn
Bleacher. "IMPROVEMENTS IN MACHINERY FOR SHAKING AND STRAIGHTENING
YARN."
.
My Invention is an improvement upon the ordinary machine now in use for
stretching and straightening yarn in the dry state, and it consists in making the
rollers upon which the yarn moves to revolve, and in the application of a cam or
other equivalent to give the shaking motion which is now effected by hand
labour. The object of this is to shake and straighten the yarn in a damp
state during the process of bleaching, whereby a considerable saving in the cost
of shaking and straightening is effected. Between the ordinary upright frames I
place driving gear which act upon the lower horizontal rollers or bars which
move up and down and rotate in the frames. The upper rollers are carried
round by the hanks of yarn under operation. These rollers may be made of
metal, wood, or other suitable material.

YARN."
My Invention is an improvement upon the ordinary machine now in use for
stretching and straightening yarn in the dry state, and it consists in making the
rollers upon which the yarn moves to revolve, and in the application of a cam or
other equivalent to give the shaking motion which is now effected by hand labour.
The object of this is to shake and straighten the yarn in a damp state during the
process of bleaching, whereby a considerable saving in the cost of shaking and
straightening is effected. Between the ordinary upright frames I place driving
gears, which act upon the lower horizontal rollers or bars which move up and down
and rotate in the frames. The upper rollers are carried round by the hanks of
yarn under operation. These rollers may be made of metal, wood, or other suitable
material.
And in order that my Invention may be fully understood I will describe the
accompanying Sheet of Drawings.
Fig. 1 is a side elevation; and Fig. 2, a front view of a machine to which my
improvements are applied; a, a, are the upper rollers or bars loose on the shaft al;
and b, b, are the lower rollers or bars fixed on the shaft b'; c, c, are cams also fixed on
the shaft b', working on bowls & for raising the shaft b'; e is a clutch-box on the
shaft b', by which the shaft is thrown in or out of gear with the wheel f, driven
from the driving shaft by a train of wheels in the usual manner.
The mode of operation is as follows:-When the attendant has placed the hanks
of yarn on the rollers or bars a and b the clutch box e is thrown into gear with the
wheel f, and the shaft b¹ in revolving is raised by the cams c, and is allowed to fall
by its own gravity, the whole weight of the shaft and of the bars b coming upon
the hanks of yarn at each revolution of the shaft b', thus shaking, stretching, and
straightening the yarn more quickly and efficiently than by any process hitherto
used by this means ten or twelve hanks, doffins, or lay downs of yarn may be
stretched and straightened at once on each pair of rollers or bars. The rollers or
bars b in revolving carry round the yarn and act upon every portion of the hanks.
The shaft carrying the bowls & may be raised or lowered to suit any length of
hank.
Having thus stated the nature of my Invention, and described the manner of
performing the same, I wish it to be understood that I do not claim any of the well
known parts of the ordinary construction, but what I claim is the manner of
driving, raising, and dropping the lower rollers or bars of machines for shaking,
stretching, and straightening yarn as hereinbefore described, also in imparting
rotary motion to the upper rollers or bars by the yarn.
In witness whereof, I, the said Samuel Knowles, have hereunto set my hand
and seal, this Third day of June, One thousand eight hundred and seventy
nine.
SAMUEL KNOWLES. (L.S.)
