We, JAMES ATHERTON, of Preston, in the County of Lancaster, Machine
Maker, JOHN KINLOCK, of the same Place, Manager, and JOHN SWAINSON,
junior, of the same Place, Worsted Manufacturer, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
SIZEING OR DRESSING YARNS OR THREADS " to be as follows:-
This Invention relates to various novel modifications and arrangements
of machinery of the kind which is technically known as the "tape sizeing
machine," ordinarily used for sizeing or dressing yarns for the manufacturer.
In these new arrangements the squeezing rollers are not actuated simply by
the tensional action of the yarn or threads under treatment, but are driven in
a positive and certain manner through the agency of gearing, and mechanical
connections in the arrangement preferred. The squeezing rollers are driven
from the first or main driving shaft of the machine, on the end of which shaft
a spur wheel driving an intermediate stud wheel; the latter carries a bevil
wheel, driving a horizontal shaft at right angles with the main shaft; at the
opposite end of the horizontal shaft as a pair of bevil wheels, driving a small

page_text: upright shaft, which works the squeezing rollers. When the yarn is finished,
it is wound upon the weaver's beam by the agency of a frictional motion. This
friction motion is similar to that already in use for winding the yarn on to
the beam in the ordinary dressing frame. At one end of the shaft, which is
actuated from the tapered drum shaft, and which crosses the machine and
works the yarn beam, is placed a toothed wheel, revolving separately from the
shaft, and between two disc plates, which are fixed to the shaft. By means of
two thumb screws, passing thro' the disc plate and pressing against the face of
the wheel, the wheel can be connected with the disc plates as tightly as may
be required. The object of this is that the yarn may be wound on the beam
at the same speed as it is delivered from the cylinders. As the quantity of
yarn on the beam increases, it begins of course to take up faster, and as the
delivery of yarn from the cylinders is positive, a great strain would take place.
As soon as the yarn begins to tighten, the toothed wheel will slip & move
faster than the disc plates, and prevent the yarn from being taken up too fast.
By this means any quantity of yarns, however fine, may be subjected to the
sizeing process. The tin drying cylinders or revolving drums are actuated by
the same general mechanical arrangement or system of gearing, and the
brushes employed for dressing the yarn are driven in a similar manner; that is
to say, the drying cylinders and rotatory brushes are intended to be driven
from the same shaft as the squeezing rollers, and by a similar system of
gearing, so as to take off all strain from the yarn, particularly in fine numbers.
In uncoiling or winding off the crude or undressed yarn from the yarn beams
prior to the dressing action coming into play, a mechanical arrangement is
employed for the purpose of ensuring an uniform delivery from the entire
series of beams, and hence the ends of the yarn upon the several beams will
all come out or off at the same time, the delivery being a positive one,
incapable of error. Portions of these improvements or modifications thereof
are applicable to the common system of dressing.
