AN IMPROVED THREAD WINDING APPARATUS TO BE APPLIED TO SEWING MACHINES
Year: 1876

page_text: LETTERS PATENT to Charles Holt, of Oldham, William Sutcliffe, of Bolton,
and William Richard Fisher, of Salford, all in the County of Lancaster, for
the Invention of "AN IMPROVED THREAD WINDING APPARATUS TO BE APPLIED
TO SEWING MACHINES."
Sealed the 23rd June 1876, and dated the 13th April 1876.
PROVISIONAL SPECIFICATION left by the said Charles Holt, William
Sutcliffe, and William Richard Fisher at the Office of the Commissioners of
Patents on the 13th April 1876.
CHARLES HOLT, of Oldham, WILLIAM SUTCLIFFE, of Bolton, and WILLIAM
RICHARD FISHER, of Salford, all in the County of Lancaster. AN IMPROVED
"
THREAD WINDING APPARATUS TO BE APPLIED TO SEWING MACHINES."
This Invention consists principally in the addition to the ordinary winding
apparatus of a self-acting guide for guiding the thread evenly and regularly on to
the spools employed in the shuttles of sewing machines.
We employ the ordinary spindle driven by an india-rubber covered wheel or
roller running in contact with the fly wheel of the machine, and having a cup-
shaped head for actuating the spool, which is held on the other side by a stud forced
forwards by a spring.
On the outside of the cupped head of the spindle we form a screw or worm
which gives a slow rotary motion to a worm wheel keyed on one end of a short
shaft or spindle.
On the other end of this shaft is a spur pinion driving a spur
wheel turning on a fixed stud. On the face of this spur wheel is fixed or formed
a cam, which as the wheel revolves gives a slow to-and-fro motion to a bowl fixed
on one end of a bell-crank lever, the other end of which is provided with a hook
or notch so as to serve as a thread guide. The bowl is kept in contact with the
cam by means of a spring, and thus as the spool is caused to revolve rapidly by
the revolution of the spindle the thread is guided and laid evenly and regularly
upon the same.

page_text: Besides the great regularity thus obtained another advantage is gained, which
is that the guiding of the thread being perfectly self-acting the spools can be
wound whilst the machine is sewing without requiring any attention beyond an
occasional glance from the attendant to see that the spools do not become too
full.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Charles Holt, William Sutcliffe, and William Richard Fisher in the
Great Seal Patent Office on the 13th October 1876.
CHARLES HOLT, of Oldham, WILLIAM SUTCLIFFE, of Bolton, and WILLIAM
RICHARD FISHER, of Salford, all in the County of Lancaster. "AN IMPROVED
THREAD WINDING APPARATUS TO BE APPLIED TO SEWING MACHINES."
This Invention consists principally in the addition to the ordinary winding
apparatus of a self-acting guide for guiding the thread evenly and regularly on to
the spools or shuttle bobbins employed in the shuttles of sewing machines.
Such being the nature and object of our said Invention we will now proceed to
describe in detail the manner in which the same is to be or may be performed
or carried into practical effect; and in order that the same may be clearly under-
stood we have hereunto annexed a Sheet of Drawings illustrative thereof, and have
marked the same with figures and letters of reference corresponding with those in
the following explanation thereof :-
Fig. 1 is an elevation and Fig. 2 a plan view (drawn full size) of an ordinary
winding apparatus for winding the said spools or shuttle bobbins with our improved
self-acting guide shown as applied thereto.
We employ the ordinary spindle a, a, driven by an india-rubber covered wheel
or roller b, b, running in contact with the fly wheel of the sewing machine, and
having a cup-shaped head c, c, for actuating the spool, which is held on the other
side by a stud d, d, forced forwards by a coiled spring.
On the outside of the cupped head of the spindle a, a, we form a screw or worm
which gives a slow rotary motion to a worin wheel e, e, keyed on one end of a
short shaft or spindle f, f. On the other end of this shaft f, f, is a spur pinion g, g
driving a spur wheel I, h, turning on a fixed stud. On the face of this spur wheel
is fixed or formed a cam i, i, which as the wheel revolves gives a slow to-and-fro
motion to one end of a bell-crank lever k, k, the other end of which is provided
with a hook or notch , l, so as to serve as a thread guide. The lever is kept in
contact with the cam i, i, by means of a spring m, and thus as the spool or shuttle
bobbin is caused to revolve rapidly by the revolution of the spindle, a, a, the
thread is guided and laid evenly and regularly upon the same; m, n, is a clip, by
means of which the improved guide or apparatus is attached to the bracket of the
winding frame.
The hook or notch 1, 1, is made adjustable on the end of the bell
crank lever k, l, to suit different lengths of bobbins.
Besides the great regularity thus obtained another advantage is gained, which is
that the guiding of thread being perfectly self-acting the spools or shuttle bobbins
can be wound whilst the machine is sewing without requiring any attention beyond
an occasional glance from the attendant to see that the spools do not become
too full.
Having now described the nature and object of our said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, we wish it to be understood that we claim as our Invention the construction
and adaptation to the ordinary spool or shuttle bobbin winders of sewing machines

page_text: of a self-acting thread guide, constructed and operating substantially as herein-
before described and illustrated by the Drawings annexed.
In witness whereof, we, the said Charles Holt, William Sutcliffe, and William
Richard Fisher, have hereunto set our hands and seals, this Twelfth day
of October, in the year of our Lord One thousand eight hundred and
seventy-six.
Witnessed by
CHARLES HOLT.
