CERTAIN IMPROVEMENTS IN MACHINES APPLICABLE TO EVERY DESCRIPTION OF SPINNING
Year: 1816

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
WOOD the younger, Manufacturer of Worsted Yarn, of Bradford, in the
County of York, and JOSHUA WORDSWORTH, Machine Maker, of Holbeck, in
the said County of York, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Second day of March,
in the fifty-sixth year of His reign, did give and grant unto us, the said John
Wood and Joshua Wordsworth, our executors, administrators, and assigns,
His special licence, full power, sole privilege and authority, that we, the said
John Wood and Joshua Wordsworth, our executors, administrators, 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, our Invention of "CERTAIN IMPROVEMENTS IN MACHINES
APPLICABLE TO EVERY DESCRIPTION OF SPINNING;" in which Letters Patent
there is contained a proviso obliging us, the said John Wood and Joshua
Wordsworth, under our hands and seals, or under the hand and seal of one
of us, to cause a particular description of the nature of our said Invention,
and in what manner the same is to be performed, to be inrolled in His
Majesty's High Court of Chancery within two calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same (relation being thereunto had) may more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, we, the
said John Wood and Joshua Wordsworth, do hereby declare that the nature

page_text: is described as follows, that is to say:-
In order to show clearly in what our improvement consists, we have repre-
sented by the Drawings in the margin hereof the new work, connected or
combined with the old, and shall distinguish that which is of our Invention
from that which was known or in uso before.
Figure 1 is an elevation or front view of part of a spindle head or frame,
shewing one spindle, with flyer and bobbin, ready for work.
Figure 2, sectional side view of the same, without the flyer, in order to shew
the manner of constructing the spindles, and mounting them with flyer, bobbin,
collar, and pully.
Figure 3, plan of frame.
Shoulders
A, A, A, A, the frame or spindle head, which is made of cast iron or any
other proper material, of any length, according to the number of spindles
required, and with holes in the top and bottom rails at proper and correspond-
ing distances, in order to receive the intended number of spindles. B, B, the
spindles, passing through the holes above mentioned, and fixed at a, a, by
screws, which are tapped into the head or frame A, A, so as to press firmly
against the said spindles, to prevent them shaking or vibrating; but any other
mode of obtaining this purpose may be adopted. The holes in frame A, A,
through which the spindles B and rods K are to pass, must of course be
adapted to the shape of the said spindle and rod, see Figure 3.
or increased thicknesses of the frame are left where the spindles are to go
through it, in order to receive the screws a, a. C, Figure 2, is a collar on the
spindle B, and resting on the frame A, A. D, D, Figure 1, the flyer, sus-
pended at the top of spindle B, by the centre E. E is the centre, made of
steel or any other suitable material, which is screwed or otherwise fastened
in the top of the flyer, and that centre running in a concave centre formed at
the top of spindle B, or by forming any other centre that would answer the
same purpose. Fis a pully or whire, to which the flyer D is screwed or other-
wise fastened, which, being connected to a cylinder or drum, or any other
communicating power, of course gives to the flyer the revolving motion requi-
site to effect the operation of twisting the yarn or thred. G, a wire or rod of
steel, iron, or any other proper material, which is made to pass and work freely
through holes made in frame A and collar C, as far as into the hoop or bush H,
into which it is inserted, as represented by the sectional side view at H. H, a
metal bush or hoop, on which the bobbin I is supported. K, K, the traverse
rail. L, L, rods, firmly fixed to traverse rail K, K, which are made to pass
freely up and down through holes in frame A, A. M, M, screws, fixed in the
traverse rail K, K, the ends of which are made concave to receive the lower

page_text: ends of wires or rods G. These screws, being raised or lowered by the hand,
regulate the bobbin I, causing the yarn or thread to be wound properly thereon.
Motion being given to the traverse rail K, K, by the heart wheel, well known
in spinning machinery, or any other proper motion, the bobbin I is thereby
traversed on the spindle B so as to cause the thread, represented as passing
through the twisted wire at d in flyer D, to be wound evenly on the surface or
cylindrical part of the said bobbin I, which, when the quantity of yarn coiled
or wound upon the said bobbin renders it necessary to remove, and replace it
with an empty one, it is with facility and expedition effected by simply raising
the flyer from its bearing upon the top of the spindle, and allowing it to fall
back, which admits of sufficient space to take the bobbin from the spindle.
Although we have shewn, in the annexed Drawing and description, old parts
combined with the new parts of our Invention, yet, that we may not appear to
claim more than we are entitled to, we think it proper to point out distinctly
the part which constitutes our improvement, viz', the mode of suspending the
flyer at the top of the spindle, and its revolving upon a centre, that centre
being formed either in the top of the flyer or at the top of the spindle;
the advantages of which mode are, compared with the plan in general use,
very obvious, hereby a considerable reduction being effected in the quantity of
power required to produce the necessary twist in the yarn or thread, as well
also in the expence attendant upon repairs.
We have not thought it necessary to describe particularly of what material
every minute part shall be made, that knowledge being sufficiently obvious to
every machinist and spinner; and we have not been describing an entire new
machine, but only improvements in old ones.
Witness our hands and seals, this Twentieth day of April, in the year of
our Lord One thousand eight hundred and sixteen.
