CERTAIN IMPROVEMENTS IN MACHINERY FOR REDUCING OR CONVERTING WOOL INTO SLIVERS OR THREADS OF ANY DESIRED LENGTH, UNLIKE WORSTED, NAMELY, PRESENTING MORE NUMEROUS HAIR POINTS PROJECTING FROM THE SURFACE OF THE SLIVERS OR THREADS
Year: 1825

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
DAVIS, of Leeds, in the County of York, and of the Bourne, Gloucestershire,
Engineer, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Seventh day of May, 1825, in the sixth year of His
reign, did, for Himself, His heirs and successors, give and grant unto me, the
said William Davis, His especial licence, that I, the said William Davis,
my exors, admors, and assigns, or such others as I, the said William Davis,
my exors, adiñors, and assigns, should at any time agree with, and no others,
from time to time and at all times 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 "CERTAIN
IMPROVEMENTS IN MACHINERY FOR REDUCING OR CONVERTING WOOL INTO SLIVERS OR
THREADS OF ANY DESIRED LENGTH, UNLIKE WORSTED, NAMELY, PRESENTING MORE
NUMEROUS HAIR POINTS PROJECTING FROM THE SURFACE OF THE SLIVERS OR
THREADS;" in which said Letters Patent there is contained a proviso obliging
me, the said William Davis, by an instrument in writing under my hand and
seal, particularly to describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, and to cause the same to le
inrolled in His Majesty's High Court of Chancery within six calendar month;
next and immediately after the date of the said in part recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Davis, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the Drawing hereunto annexed, and the following
description thereof (that is to say):-
Fig. I. is a vertical section of part of my Invention.
Fig. II. is a view at right angles, and answering as a section to Fig. I.,
exclusive of the framework, which it is not necessary to shew, as that appears
sufficiently clear in Fig. I., and may be varied in shape agreeably to the judge-
ment of the engineer. A and B are cylinders, partly covered with fillet cards, fixed
on the circumference of them at right angles to the length of the cylinders; one
inch, more or less, of the length is covered with card, and the next inch, more or
less, equal to the breadth of the card, left without card, alternately the whole
length of the cylinders, but the cylinder A is covered opposite the spaces of
the cylinder B, in order that wool may be taken from the whole length of the
large cylinder of a common carding machine, part of which is represented by
the section at C, Fig. II. The circular cards D receive the wool from the
cylinders A & B, and causes a complete change in the direction of the wool
hairs compared with the length of the sliver or thread, and this constitutes
the first part of my said Invention. E, H, are cog wheels; F, G, are axles;
I, rollers, similar to the feeding rollers used in mule jennies, these are shown
broken off at a, for the purpose of showing the comb b, broken off also at tho
ends. K is a radius bar to give the comb b a direction when working,
corresponding with the direction of the wires of the circular cards D. M
is the frame. N, spindles and flyers, as used in machinery for spinning of
flax.
The second part of my Invention consists in the compound drawing and
twisting of the threads, without stopages for copping or winding, as in mules or
jennies, and represented by Figs. III., IV., V., VI., VII. Fig. III. is a longitu-
dinal section. Fig. IV. is a section across at right angles to Fig. III. Fig. V.
is a longitudinal section of the middle part or axis, and at right angles to Fig. III.
a is a pulley, the interior circle of which is formed into cogs of very fino
pitch. is a pinion taking into the teeth of a. c is a roller kept against the
pinion b by a spring d. e is part of the axles.
axle e; the pullies a are moveable on the axles e.
axles e are driven. One or more of these compound drawers and twisters may
be applied to each sliver or thread between the spindles and flyers, Fig. II., and
rollers I, or they may be used instead of the rollers I; or the first part of my
Invention may be worked seperately, as represented at Fig. II., and the thread
f are guide eyes fixed in the
9, pullies by which the

page_text: may be drawn by rollers from the bobbins, and further reduced by the com-
pound drawers and twisters in a separate frame, and received with spindles,
flyers, and bobbins, as at Fig. II. Any desirable number of threads may be
acted upon in one machine, which must be furnished with riggers or drums,
with a variety of speeds, to drive and adjust the speeds of the drawing pullies a
and twisting pullies g. By this machine every thread can be drawn and twisted,
untwisted, drawn and twisted, any desirable number of times at the same
instant. The operation is as follows:-The slivers are received from the
circular delivering cards D, or from the rollers I, or from bobbins taken from
the spindles and flyers N, placed in a suitable frame or stand attached to the
drawer and twister frame, passing through the hollow axis of Fig. III., VII., VI.,
between the pinions 6 and rollers c, through the guide eyes f, on to bobbins
with flyers and spindles, as at Fig. II. The drawing rollers b, c, might be
placed at right angles to the riggers if thought proper, without altering the
principle of drawing and twisting, and one of the cylinders A, B, and setts of
spindles and flyers would take the whole of the wool from the cylinder c, by
giving to it a reciprocating motion in the direction of the length of its axle,
equal to the breadth of the fillet card applied.
In witness whereof, I, the said William Davis, have hereunto set my
hand and seal, this Second day of November, in the year of our Lord
