page_text: LETTERS PATENT to Joseph Stubbs, of Manchester, in the County of
Lancashire, Machine Maker, and John Corrigan, of the same Place,
Mechanic, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
WINDING TWO OR MORE YARNS OR THREADS OF COTTON AND OTHER FIBROUS
MATERIALS ON TO ONE BOBBIN OR SPOOL PREPARATORY TO DOUBLING THE
SAME.
"
Scaled the 19th December 1873, and dated the 24th June 1873.
PROVISIONAL SPECIFICATION left by the said Joseph Stubbs and
John Corrigan at the Office of the Commisioners of Patents, with
their Petition, on the 24th June 1873.
WC, JOSEPH STUBBS, of Manchester, in the County of Lancaster,
Machine Maker, and JOHN CORRIGAN, of the same Place, Mechanic, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR WINDING TWO OR MORE YARNS OR THREADS OF COTTON AND OTHER
FIBROUS MATERIALS ON TO ONE BOBBIN OR SPOOL PREPARATORY TO DOUBLING THE
SAME," to be as follows:-
.
Our Invention relates firstly to a method of arresting the rotation of
the bobbins or spools when a yarn or thread is broken, for which purpose

page_text: .
we cause a blade when a breakage takes place to be thrust between the
parts which give motion to the bobbin or spool, and the motive power is
consequently withdrawn.
The arrangement we propose is as follows:-The shaft of the bobbin
or spool is driven by a surface drum acting against a roller fixed to the
said shaft, and beneath these surfaces is placed a blade extending from a a
lever which is capable of turning downward, but is prevented from doing
so during the proper working of the machine by a catch. The yarns or
threads pass through curls, each one of which is carried by a separate
arm, and is provided with a part hanging downward above a plane, in
.which there is situate a constantly reciprocating bar. When an end
breaks the tension of the yarn or thread no longer supports the curl, and
it falls downward, carrying with it the above-mentioned hanging part,
which then occupies a position in the same plane as the reciprocating
bar, and being thrust forward acts against the holding catch and allows
the lever which carries the aforesaid blade to fall, and its other end
rising the said blade is thrust between the driving surfaces, and the
motion of the bobbin or spool is arrested.
In place of the above-mentioned method of driving the bobbins or
spools a line shaft may carry pullies acting against drums, which drive
the bobbins or spools by direct surface action, and between these.pullies
and drums the aforesaid blade may act.
Another part of our Invention relates to the apparatus for guiding the
yarns or threads to the bobbins or spools, for which purpose we use two
or more guide bars instead of one, our object being to test the strength
of the yarns or threads as far from the bobbins or spools as is
practicable.
Another part of our Invention consists in a method of fastening the
bobbin or spool to the shaft upon which it is mounted. For this purpose
we provide the shaft with an expanding casing, which will contract by
pressure.

filed by the said Joseph Stubbs and John Corrigan in the Great Scal
Patent Office on the 24th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JOSEPH
STUBBS, of Manchester, in the County of Lancaster, Machine Maker,
and JOHN CORRIGAN, of the same Place, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of Junė, One
thousand eight hundred and seventy-three, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Joseph Stubbs and John Corrigan, Her
special license that we, the said Joseph Stubbs and John Corrigan, our
executors, administrators, and assigns, or such others as we, the said
Joseph Stubbs and John Corrigan our 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 the Isle
of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR WINDING Two
OR MORE YARNS OR THREADS OF COTTON AND OTHER FIBROUS MATERIALS ON TO
BOBBINS OR SPOOLS PREPARATORY TO DOUBLING THE SAME," upon the condition,
amongst others that we, the said Joseph Stubbs and John Corrigan,
by an instrument in writing under our hands and seals, or under the hand
and seal of one of us, 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 I, the said Joseph Stubbs, 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 and accompanying Drawings, that is to say :-
Our Invention relates to a method of arresting the rotation of the
bobbins or spools when a yarn or thread is broken,
for which purpose
wo

page_text: governed may be varied, but we will now describe that which we have
found to answer the purpose in a simple manner.
In the accompanying Drawings Fig. 1 shews in section so much of
a winding frame as will suffice for explaining our Invention; and Fig. 2
is a plan view thereof.
At 1 is the line shaft, on which the surface drums (one of which is
seen at 2) are mounted, for causing the bobbins or spools 3 to rotate,
so that the yarns or threads indicated by the blue lines may be wound
thereon.
In the Drawing one head only of the machine is shewn, and the
number of yarns or threads to be wound together aro six, but any other
Lamber may in like manner be combined. These yarns or threads
pass, as usual, from a creel and over rods 4, 5, between which there
are curls 6, carried at their lower ends by arms 7, 7*, turning upon fixed
centres 8, and provided at their other ends with blades 9, capable of
sliding vertically in guides 10, and passing upward to a position beneath
the points of contact of the surface drum 2 and bobbin 3. The shaft
which carries the bobbin in any usual manner is mounted on levers 11,
which turn upon a fixed centre 12, borne forward by a weighted lever 13
so as to cause the bobbin to press against the surface drum. To one of
the levers 11 is jointed an arm 14, which according to the position shewn
rests by means of a stop 15 on the rail 16, and at 17 is an arm fixed to
the other lever 11, which after curving downward is provided with a
cross piece 18, extending over and across the arms 7, 7*. At 19 is the
guide, which in the usual manner collects the several yarns or threads,
and traverses them upon the bobbin while they are being wound.
The operation is as follows:-The parts shewn being in their proper
working positions, and it being understood that the tension of the yards
or threads supports the heavier ends 7 of the arms 7, 7*, so as to prevent
them from turning upon their centres 8.. Should an end break then the

page_text: curl 6 to which it belongs, being no longer held up, will pass downward
and allow the arm 7, 7*, to turn upon its centre 8, by which means the
blade 9 will be thrust upward between the surface drum 2 and bobbin 3,
and the former by its rotation in the direction of the arrow will tend to
draw it still further, and it therefore becomes interposed between. the
motive power and the bobbin, which will consequently cease to revolve
and to draw off the unbroken ends, that which is missing being then
pieced up. In order to facilitate this operation the attendant thrusts
forward the arm 14 until the stop 15 falls over the edge of the rail 16,
by which means the levers 11 are turned further upon,their centro 12,
carrying with them the bobbin, which is retained in that position by the
aforesaid catch, at the same time the arm 17, by turning with the
lever 11, brings the cross piece 18 to bear against the elevated end 7* of
the arm, thereby moving downward the blade 9, and turning upward the
curl 6 into the position shewn, after which the piecing may be effected,
and this having been done the attendant liberates the catch 15, and allows
the weighted lever 13 to draw the bobbin into contact with the revolving
surface drum.
By the above described operations the unbroken ends may have become
slack between the rollers 4, 5, and in order to bring the whole of the
yarns in the curls to their proper state of tension we adopt the following
contrivance-At 20 is a lever mounted so as to be capable of turning
upon a centre 21, and provided with a cross piece 22, which extends
under the arms 7 by turning the lever 20 upon its centre. Before the
winding is renewed the arms 7 are clevated by the cross picce 22, and
the curls are raised to their proper working position, after which the
bobbin being caused to revolve the slack of the ends is taken up, and the
lever 20 may then be released.
It will be obvious that in place of the above-mentioned arrangement
for driving the bobbins or spools a line shaft may carry pulleys acting
against drums, which drive the bobbins or spools by surface action, and
between these pullies and drums the aforesaid blades may act.
Having thus described and ascertained the nature of our said Inven-
tion, and the manner in which the same is to be performed, I desire it to
be understood that we claim as secured to us under the above in part
recited Letters Patent, and for the purpose above set forth, the use

page_text: described.
In witness whereof, I, the said Joseph Stubbs, have hereunto set
my hand and seal, this Twenty-third day of December, in the
year of our Lord One thousand eight hundred and seventy-three.
