Year: 1871

page_text: LETTERS PATENT to Thomas Unsworth, of Manchester, in the County
of Lancaster, Doubler and Machinist, and Edward Whalley, of the
same Place, Mechanic, for the Invention of "IMPROVED SELF-STOPPING
WINDING FRAME."
Scaled the 21st November 1871, and dated the 7th August 1871.
PROVISIONAL SPECIFICATION left by the said Thomas Unsworth and
Edward Whalley at the Office of the Commissioners of Patents,
with their Petition, on the 7th August 1871.
We, THOMAS UNSWORTH, of Manchester, in the County of Lancaster,
Doubler and Machinist, and EDWARD WHALLEY, of the same Place,
Mechanic, do hereby declare the nature of the said Invention for "IM-
PROVED SELF-STOPPING WINDING FRAME," to be as follows:-
Our object in this improved frame "is," that during the winding of
any number of threads on to a bobbin, should one or more of such
threads break such winding shall instantly stop until such thread or
threads are made good, and by these means may be insured a perfect
thread or cord of any number of strands. The cops or bobbins from

page_text: which we are winding are placed at the bottom of the machine, and the
strand from such passed over a knee board, with or without brush, and
through eyelets on the ends of levers fulcrumed on to a shaft secured
at each end in a bracket provided for the purpose. Bearing on to the
other ends of these eyelet levers is a rod secured into a knocking-off
lever, which knocking-off lever is fulcrumed into a bracket. The
other end of this lever is toothed or otherwise as convenience may
dictate. On such tooth or other provision is rested a fulcrumed catch
lever, "over which" and running in a frame provided for such is a catch
wheel on the shaft or spindle carrying the bobbin to be wound. On this
same shaft or spindle is a friction pulley, immediately below such is the
driven shaft, on which, and immediately under such before-mentioned
friction pulley, is another friction pulley which drives the one above.
Its action is as follows:-The threads pass from bobbins or cops over
kneeboard through eyclets in levers, and through a guide on a tra-
verse lever to bobbins; should any one or more ends break, the cyclet
end of eyelet lever being before kept up by such thread immediately
drops, thus acting on the "knocking-off lever outer end" lifting it up,
the other or tooth end or equivalent drops, and with it the front end of
catch lever, the catch raising up slips into catch wheel on bobbin shaft
or spindle instantly lifts the upper friction roller, spindle, and bobbin,
and stons it.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Unsworth and Edward Whalley in the
Great Seal Patent Office on the 7th February 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, WC, THOMAS
UNSWORTH, of Manchester, in the County of Lancaster, Doubler and
Machinist, and Edward WHALLEY, of the same Place, Mechanic, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of August, in the year of
our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Thomas Unsworth and Edward Whalley, Her
special licence that we, the said Thomas Unsworth and Edward Whalley,
our exccutors, administrators, and assigns, or such others as we, the said

page_text: "
Thomas Unsworth and Edward Whalley, our exccutors, 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 IMPROVED SELF-STOPPING WINDING FRAME,"
upon the condition (amongst others) that we, the said Thomas Unsworth
and Edward Whalley, our executors or administrators, by an instrument
in writing under our, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Unsworth and Edward
Whalley, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
:―
Our Invention consists of a suceptable mechanical arrangement for
stopping the bobbins in a winding frame when a thread breaks.
We know that a Patent was granted to Robert Smith, of Manchester,
on the 28th day of March 1870, for a similar purpose. Such Patent we
consider complicate, and not easily got at when out of repair. Likewise
when an end breaks the bobbin runs several times round before it stops,
causing the piecer to lose much time in getting the ends to piece up.
In our Invention "instantly" a thread breaks the bobbin on which it
is being wound stops, leaving the ends in sight of the piecer, without
having to search and unwind the bobbin to recover it.
Hereunto we annex a Sheet of Drawings, in the several Figures of
which similar parts are marked by corresponding letters of reference.
A, in Figures 1, 2, and 3, are the cops or other equivalent from which
we draw or wind our threads; B, dotted in Figures 2 and 3, is a cross
bar, which is covered with flanel, a brush, or other equivalent; C, C, are
spit plates to take the snicks out of the yarn; D, D, are breast boards,
over which the threads pass to eyelets a in the ends of levers E; these
levers are fulcrumed to stands F by bar G. On the other ends of
these levers E rests bar H; this bar goes through and is secured to
lever I, which lever is fulcrumed to stand brackets J, Fig. 4, which

page_text: stand behind stand bracket 6 in Figures 2 and 3. This lever I has a step
leg K (on Fig. 2), on which rests the bow end of another fulcrum
lever M, which fulcrums on to headstocks N of driven shaft O. The
end of this lever is of a catch-tooth shape, as at p, in Fig. 2, and fits the
catch wheel P. On the side of such catch wheel is a friction roller R.
A spindle S carries bobbins T, on which the several threads are wound.
Imediatly under the friction roller R and on the driven shaft O is
another friction roller U, on Fig. 2, which drives the upper friction
roller R, and by spindles S, bobbins T. The whole is driven from
shaft V by pullies W through tooth wheels X, Y, and Z; b, b, are stands
carrying a rod c, over which the threads pass to the bobbins T. There
is a regulating traverse lever d, on which and in front of each bobbin is
a "three-leged guide" h, which bands the threads together, and carries
them regularly from end to end of bobbin, so as to keep it evenly wound.
This lever is worked by heart-shaped cam e, by pivots f, which gets its
action from driven shaft O, by and through screw g and wheel i, in
Figs. 2 and 4. We regulate the traverse by a slot lever in the centre
of the machine, communicating with both traverse levers on cach side
of the machine.
Having described the several parts of our machine and their uses, we
will now proceed to describe its combine action and effect.
The several threads of yarn or other material passes from cops A
round cross bar B, through split plates C, over breast board D, through
eyelet a in the ends of levers E, over rod c, through guide legs h to
bobbins T; t is a check bar to prevent levers E from shaking off or
getting out of position. The levers E with the bars H resting on the
short end is kept up to its position by all the threads passing through
the eyelets a, and is so balanced that when one thread breaks the eyelet
end of such lever falls and lifts up bar H and that end of lever I, which
has the effect of backing out K end of such lever, when lever L end
drops down, lifting the other tooth end up, which slips into catch
wheel P, and instantly stops bobbins T (which are firmly fixed on
spindles S), and remains so stopped until such broken thread is pieced
and bobbin replaced in its proper position. The heart cam traverse
motion A1 keeps the regulating lever always moving regularly from
end to end of bobbin.
Having fully described our Invention and its action, we may remark
in connection, that independent of its other advantages, we can wind

page_text: much tighter, and put a considerable more per-centage of yarn on the
same sized bobbin than by any other process hitherto known; we wish it
to be understood that we do not confine ourselves to the precise details we
have had occasion to describe herein, as many variations can be made in
detail without deviating from the principle, nor do we seek to claim any
part of the arrangement mechanicaly of the before-mentioned Robert
Smith; but what we do claim as novel and secured to us herein is,-
First. The levers E, I, and M, substantialy as herein described and
illustrated.
Second. The catch wheel P and the friction rollers R and U, sub-
stantialy as herein described and illustrated.
Third. The three-leged guides on the traverse lever for banding the
threads together, substantialy as herein described and illustrated.
Fourth. The general arrangment of the several parts herein set
forth, for the purposes of self-stopping the bobbins when an end breaks
in winding frames, substantialy as herein set forth and illustrated.
In witness whereof, we, the said Thomas Unsworth and Edward
Whalley, hereunto set our hands and seals, this First day of
February One thousand eight hundred and seventy-two.
