page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BROOK ADDISON, of Bradford, in the County of York, Manufacturer, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Tenth day of February, in the year of our Lord One thousand
cight hundred and forty-two, and in the fifth year of Her reign, did, for Herself,
Her heirs and successors, give and grant unto me, the said William Brook
Addison, Her especial license, full power, sole privilege and authority, that I,
the said William Brook Addison, my exors, adññiors, and assigns, and such
others as I, the said William Brook Addison, my exors, adiiors, and assigns,
should at any time agree with and no other, 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 and Wales and the Town
of Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN MA-
CHINERY FOR SPINNING WORSTED AND WOOLLEN YARN;" in which said Letters
Patent is contained a proviso that I, the said William Brook Addison, shall
cause a particular description of the nature of my said Invention, and in
what manner the same is to be performed, to be enrolled in Her Majesty's
High Court of Chancery within six calendar months 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Brook Addison, do hereby declare that the nature of my said. Inven-

page_text: tion, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following statement thereof, reference
being had to the Drawing hereunto annexed, and to the figures and letters
marked thereon, that is to say:-
My Invention relates to a mode of producing cops of worsted or woollen
yarns spun on throstles or machines, acting similarly to throstics when to be
used as the weft in weaving. In proparing cops of worsted or woollen yarn
when to be used as weft in weaving, and spun on throstles, or machines acting
similarly to throstles, as at present practised, the spinning machinery is so
arranged as to wind the yarn, as it is spun, on to bobbins in a nearly horizontal
position, each succeeding winding of yarn on to a bobbin being only inclined out
of a truly horizontal position to the extent of the diameter of the yarn itself.
Hence, in order to obtain cops of worsted or woollen yarn suitable for a shuttle,
it has heretofore been necessary to remove each bobbin from the throstle, or
other spinning machine acting similarly to a throstle, and to place the bobbins
in another machine, and to unwind the yarn therefrom, and to build up cops by
such other machine. Now, the object of my Invention is progressively to con-
struct cops of worsted or woollen yarn by the working of the throstle or other
similar spinning machines ns the yarn is produced, thus dispensing with tho
use of the machine heretofore employed for making cops of worsted or woollen
yarn after the bobbins have been removed from the machine in which the yarn
has been spun. And in order that my Invention may be more fully under-
stood and readily carried into effect, I will proceed to explain the Drawing
hereto annexed.

page_text: ordinary manner, and which heretofore has received an uniform perpendicular
traverse equal to the whole length of the bobbin on which the yarn is to bo
wound or placed. But where my improvements are applied this uniform
copping movement is removed, and replaced by my improvement, which winds
or distributes the yarn on the bottom in the form of a cop, as seen at Figure 5,
which I shall now proceed to describe. Over a small pulley fixed at the end
of the driving shaft is placed the strap b, best seen at Figures 1 and 3, through
which motion is conveyed to the pulley C, placed on a small shaft, which
also carries the pinion C'; from the pinnion C' notion is conveyed through the
spur wheel D and worm d to the wheel E, placed on the horizontal shaft e, e,
the opposite extremitics of which carries the heart pieces f. f, see Figure 3.
These heart pieces respectively convey the copping motion to each side of the
frame, which, being in every respect alike, one only need be described. From
the slow ratation of the heart pieces f, f, a vibrating motion is imparted.
to the spring F, see Figure 4, one end of which is bolted to the framing
of the machine, and the other provided with the small pulley 'f. This
pulley f consequently receives a uniform alternating movement, guided by
the slot in the framing, as seen at f, Figure 1. The copping rail B is
supported by the lever G', which moves on a fulcrum at g, and has a constant
tendency to elevate the copping rail B by the superior weight of the counter-
poise 'G, but the position of the lever G is determined by the chain h, h, to
which it is connected. This chain is attached to the pulley H, from which it
passes over the carrier pulley 'h, and vibrating pulley f, and forward to the lever
G, as seen at Figures 1 and 3. Supposing, therefore, the pulley H to remain
stationary, the uniform vibration of the pulley f will be imparted to the
lover G, and thence to the copping rail, so that at the commencement of spin-
ning, the yarn or thread would be distributed (by a short traverse on the lower
part of the bobbin), as seen at Figure 3; but the pulley H is placed on a
shaft which also carries the worm wheel I, to which a slow motion is conveyed by
the revolution of the worm i, so that the rotation of the pulley H is uniformly
taking up part of the chain 'h, 'h, which (through the lever G) consequently
gradually depresses the copping rail, causing the distribution of yarn to pro-
ceed higher up the bobbin till the whole is filled with yarn or thread, as seen
at Figure 5. As it is of importance that the spinning frame should cease
to run as soon as the bobbin is filled, a small lever M is placed on the
shaft g, which, as soon as the bobbin is filled, arrives in contact with the
spring catch N, and forcing it out of the notch in the guide N¹ allows it
to throw off, the driving strap in the ordinary manner; while at the same
time another lever O, also placed on the shaft g, come in contact with the

page_text: pulley H, and disconnects it from the shaft on which it is placed, thereby
allowing the weight 'G to fall, the copping rail B to rise, and the pulley II
to resume its proper position for recommencing spinning on the empty
bobbin. The construction of the pulley II and the form of the lever O
is best seen in section at Figure 9, where it is seen held up in the
proper position for spinning, by means of a spiral spring in the box or
centre, and connected with the shaft by a pin taking into a hole in the
side of the pulloy; but as soon as the pulley H is forced endwise on the
shaft (by the bevel end of the lever O), and into the position indicated by
dotted lines, it is free, and immediately give off the band h, and resumes its
original position, as described. It will be observed that the bobbins used
in this process have no flange at the upper end, so that the yarn may come off
freely in the process of weaving when placed in the shuttle, and that the flyers,
which, with the ordinary bobbin used for spinning, are required of a span or
width as seen at Figure 8; are now reduced to the size as seen at Figure 7,
by which the friction or rubbing of the yarn on the flange of the old bobbin
is obviated, and the yarn produced of a smoother and more perfect quality.
From what has been explained in the foregoing description, it will be seen
that I not only produce a superior quality of yarn, but that the bobbin, holding
much more than an ordinary cop, and having no ties or knots (as when
re-wound), the weaving process proceeds with less interruption, and a con-
siderable economy is effected in the production of the cloth.
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would have it understood, that I make
no claim to any of the parts separately, nor do I confine myself to the
pricise details, so long as the machinery is suitably arranged for carrying
out my Invention; and, although I have confined my description herein to
my Invention as applied to the common throstlo spinning machine, yet I do
not confine myself wholly thereto, there being spinning machines which are
called by other names than the throstle, yet acting for the most part in a
similar manner to the throstle as regards their continuous spinning and
winding up of the yarn; and it will be evident to persons acquainted with
such machines, that, by making allowance for the differences in respect to
the throstle, the description of my Invention above given will enable a work-
man to construct such other continuous spinning machines to produce cops
of worsted or woollen yarn suitable for the shuttle. And I would state, that
I have been informed that it has been before proposed to spin cotton ou
throstles, or spinuing machines acting similarly to throstles, anil to construct
copis of cottoni yarn proper for the shuttle, I believe, howover, without suc

page_text: cess; and it may have been proposed to produce cops of yarn of other
fibres. I mention these matters in order to state that my Invention is con-
fined to the making of cops of worsted or woollen yarns; and I make no
claim to the preparing of cops of cotton, or other fibrous materials not being of
wool, when spinning by a throstle or similar machine. And I wish it to be
understood, that what I claim is, the mode of producing cops of worsted
or woollen
yarn suitable for the shuttle, by causing the cops to be built up
progressively, as herein-before described, as the yarn is spun in a throstle, or
other spinning machine acting similarly to a throstle.
In witness whercof, I, the said William Brook Addison, have hereunto
set my hand and scal, this First day of August, in the year of our
Lord One thousand eight hundred and forty-two.
