Im- PROVEMENTS IN STOP MOTION WINDING DOUBLING FRAMES
Year: 1875

page_text: LETTERS PATENT to Thomas Unsworth, of Manchester, in the County
of Lancaster, Machinist and Doubler, for the Invention of "Im-
PROVEMENTS IN STOP MOTION WINDING DOUBLING FRAMES."
Sealed the 23rd December 1875, and dated the 28th June 1875.
PROVISIONAL SPECIFICATION left by the said Thomas Unsworth at
the Office of the Commissioners of Patents, with his Petition, on
the 28th June 1875.
I, THOMAS UNSWORTH, of Manchester, in the County of Lancaster,
Machinist and Doubler, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN STOP MOTION WINDING DOUBLING FRAMES,"
to be as follows:―
On the 7th day of August 1871, Letters Patent were granted to me and
Edward Whalley for improved self-stopping winding frame, and num-
bered 2077. I lodged likewise a Provisional Specification of a further
improvement in same machine on the 30th day of September 1878.
This I embodied with still further improvements in a complete specified
Patent on the 18th day of April 1874, and numbered 1268,

page_text: My present Invention does not in the least interfere with any of those
improvements, but consists of other and further improvements, whereby
a positive method of driving is obtained, and any number of ends of the
finest yarn may be wound at the same time.
'I use the L lever K, with its shelf end 61 of levers o and in my {
former Specifications and Drawings.
I carry my yarn from bobbins or cops fixed, as before, over a friction
rod roller or pulley in front of machine, thence through the eyelet at
the top or vertical end of a L. lever fulcrumed at the heel. To the other
or horizontal end of same lever is loosely jointed a pendent rod. The 1
lower end of this pendent rod, when the yarn is whole and passed
through the eyelet end, carry over the vertical end of such lever towards
the centre of the machine, is thereby lifted, and immediately under the
end when held in such position works a rod connected at each end to
the outer ends of two or more cranks. This rod has a too-and-fro 1
motion. The lower and larger ends of these cranks are keyed on a rod
freely worked in bearings on the frame. The too-and-fro motion is
obtained by a connecting rod, cam, or crank from any convenient part
of the machine.
I use a leg lever, with shelf, same as before-mentioned Patents, and i
marked on my Drawing Fig. 18, the rod in the O end being made long
enough to be acted upon by a number of pendent rods equivalent in
number to the yarn ends being wound. As long as the yarn ends
remain whole (as in my before-mentioned Patents) this o, n, lever
remains perfectly horizontal, and the pendent rods are all above the
cranks and rod with its too-and-fro motion, and the rod in the end of
o, n, lever is likewise free of such action, but when an end breaks the
vertical eyelet end of L lever falls back, the lower end of pendent rod
is thus brought down, and in contact with the too-and-fro rod in action
and the inside of rod in the O end of O, N, lever, thereby lifting it, thereby
bringing shelf of leg 6' on same lever from under M end of lever K (as
in before-mentioned Patent), thus instantly stopping the bobbin.
On the traverse slide bar or any other convenient part of the machine
I fix a bracket to carry a bowl with a smooth surface, round which I
pass the yarn before it is delivered to the take-up bobbin; this entirely 8
provents the possibly of slack ends in the yarn. On the same bar I
likewise fix an adjustable screw "thread guide," which enables the

page_text: minder to set the thread to any point without the use of a screw key,
-preventing thereby any liability to slip or get out of order.
I use likewise a positive driving apparatus consisting of my usual
double L lever, as before named in my Specification of April 13th 1874,
but instead of the two friction rollers to drive the bobbin I fix on the
bobbin spindle a spur wheel, also on the driving shaft a corresponding
wheel for driving the same. It will thus be seen that by the action of
the double lever, as before, lifted back by its usual action, will bring
the wheels into gear, giving thereby a positive motion to the take-up
bobbin, which enables me to wind from the heaviest bobbins, which is
impossible to do by friction. By these means any number of ends of
the finest yarn may be wound at the same time.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Unsworth in the Great Seal Patent Office
on the 28th December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
UNSWORTH, of Manchester, in the County of Lancaster, Machinist and
Doubler, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eight day of June, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Unsworth, Her special licence
that I, the said Thomas Unsworth, my executors, administrators, and
assigns, or such others as I, the said Thomas Unsworth, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
STOP MOTION WINDING DOUBLING FRAMES," upon the condition (amongst
others) that I, the said Thomas Unsworth, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the

page_text: --
Arrangement, Figures 2 & 8.-O, leg end of E side lever; P, steel
resting plate; R, ledge or shelf end for plate P to rest upon when
machine is in motion; 8, rest or shear end of same; T, rod or har
running the whole length of the machine, connected at each end by
cranks W, which is secured to rod r, and working in suitable bearings
at intervals; U is a connecting rod, which gives motion to cranks from
eccentric V, working on end of driven shaft n; a is a bowl, round
which I pass the yarn from the adjustable thread guide 6, also fixed on
the guide bar g; c, a spindle on which the bowl works.
Having described the several parts of my improved machine and
its mechanical arrangements I will now proceed to describe its action
and effects.
L
I carry, my yarn d, e, from bobbins or cops fixed, as before, over a
friction roller, rod, or pully in front of machine, thence through an
eyelet at the top at i in Figure 1, and i likewise in Figure 3, or over a
bar and under a bar or rod at h, from thence to thread guide 6 (if
required round bowl a), thence to take-up bobbins behind spur wheel K.
As long as all the yarn ends remains whole the machine and all its parts
remain, as shewn by the left-hand side, in full action, but when an end
breaks the lever L at the end marked assumes a vertical position, as
shewn in the right-hand side; the drop rods m consequently fall, and
are forced outward by the bar or rod T (which has a constant too-&-
fro motion); this drop rod m is forced outward against the inside of
longitudinal rod Y, and thereby lifting that end of lever N fulcrumed at
u, thus draws the shelf or stop end of same lever from under steel
plate P, allowing same to drop drown, by means of which the O end of
double side lever E carrying take-up bobbin and driven wheel K from
the centre forward, consequently out of gear, coming in instant contact
with G bracket is immediately stopped. When I use the arrangement
shewn by Figures 2 & 3 I dispense with bracket O, lever N, and
L lever L, and simply carry the yarn through eyelet i, Figures 8, thence
over bar i, Figure I. to thread guide and take-up bobbin. This bowl, if
the yarn is passed once or twice round previous to going to take-up
bobbin, prevents the possibility of slack ends in the yarn.
Having now described my Invention, and the way I work it, I wish it
to be distinctly understood that I do not confine myself to the precise
details I have had occasion to describe or refer to, as many variations in
