AN IMPROVED SPINDLE FOR THE MANUFACTURE OF SILK, THREAD, AND VARIOUS OTHER ARTICLES
Year: 1814

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
COURTAULD, of Braintree, in Essex, Silk Throwster, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fourth day of August, in the fifty-fourth year of His reign,
did give and grant unto me, the said George Courtauld, my exors, admors,
and assigns, His especial licence, full power, sole privilege and authority, that
I, the said George Courtauld, my exors, adññors, and assigns, during the
term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my. Invention of "AN IMPROVED SPINDLE FOR THE MANUFACTURE OF
SILK, THREAD, AND VARIOUS OTHER ARTICLES;" in which said Letters Patent
there is contained a proviso that if Ị, the said George Courtauld, shall not
particularly describe and ascertain the nature of my said Invention, and in
what manner the same is to be performed, by an instrument in writing under
my hand and seal, and cause the same to be inrolled in His Majesty's High
Court of Chancery within two calendar months next and immediately after
the date of the said Letters Patent, as by the said Letters Patent (relation
being thereunto had) may more fully appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
George Courtauld, do hereby declare that the nature of my said Invention,
and in what manner the same is to be performed, are particularly described

page_text: 1
and ascertained in the Drawings hereunto annexed, and the following
description thereof::
a, Fig. I. and III., the main spindle fixed in the cross at b, into which cross
the spindle c, c, are also fixed. d, d, Fig. III., are the whirls. e, Fig. I., is
a conical tube fixed in the whirls d, no larger at its upper and smaller end
than to admit its moving freely on the spindles c, c. f, g, are two standards
fixed also in the cross b, to support the safety hook and axis h, Fig. III. This
axis of the hook is suspended by its pivots i, i, Fig. V, between the standards,
as seen in Fig. III. The springs k, k, are fixed to the caps 1, 1, at m, and lay
in the groove n, n, shewn in Fig. I., at the top of the spindles, so that this
spring keeps the caps 1, 1, from flying off the spindles, and also the bobbins o, o,
and the whirls d, d; and these springs being relieved from the grooves in the
spindles, the caps 1, 1, the bobbins o, o, and the whirls d, d, with their tubes e,
will readily slip off from the spindles c, c. p is a circle fixed to the throwing
mill by screws at q, q, with a cross bar r, thro' the centre of which the main
spindle a passes, and in which it moves. The inside of the circle p is lined
with leather or other soft substance. The bore of the hose s is large enough
to admit its moving freely on the main spindle a. t is a moveable catch, into
which a pin is fixed, which by another pin thro' the spindle, and a stop across
the bottom of the hoses, connects or disconnects the hose from the spindle,
so as to enable each spindle to be stopped separately, while the hose s
still revolves by the pressure of the mill strap upon it. To explain the
operation of the safety hook h, Fig. III., breaking the thread: let the thread v,
Fig. III., be supposed broken by some defect or accident, the hook would
then lose the support of that thread on the opposite side of the hook (for the
threads cross each other immediately under the hook), and it would instantly
fall into an horizontal position on that side, by which it would come in
contact with the wire eye w fixed in the cap 1, and thus obstructing the
motion of the cap on the spindle c would instantly break the thread, so that
the thread or threads from one bobbin can never be taken up on the mill
without that or those on the other bobbin. The dimensions of the Draft are
very suitable for organzine silk, but for sewing silk the dimensions must be
larger and the parts stronger.
Fig. II., shews the cross into which the spindle and standards are fixed.
Fig. IV. is a geometrical draft of the circle p, Fig. III., shewing the wheels,
which when in motion are thrown by the centrifugal force against the circle
(room for that being allowed by the conical form of the tube e, Fig. II.), and
of course the whirls are made to revolve twice on their axis in one direction,
while they make one revolution of their orbit round each other, giving thereby

page_text: two turns to the thread or threads on each bobbin in one direction, then putting
those threads together, and giving them oue turn in the contrary direction a
the same time.
In witness whereof, I, the said George Courtauld, have hereunto set my
hand and seal, this Thirtieth day of September, in the year of our
Lord One thousand eight hundred and fourteen.
GEORGE COURTAULD. (L.S.)
AND BE IT REMEMBERED, that on the Thirtieth day of September, in

aforesaid, and all and every thing therein contained and specified, in form

to the tenor of the Statute made for that purpose.
Inrolled the Thirtieth day of September, in the year of our Lord One
thousand eight hundred and fourteen.
