page_text: LETTERS PATENT to Joseph Stubbs, of Manchester, in the County of
Lancaster, 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 BOBBINS OR SPOOLS PREPARATORY TO DOUBLING THE
SAME."
Sealed the 13th May 1875, and dated the 26th November 1874.
PROVISIONAL SPECIFICATION left by the said Joseph Stubbs and
John Corrigan at the Office of the Commissioners of Patents, with
their Petition, on the 26th November 1874.
We, 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 BOBBINS OR SPOOLS PREPARATORY TO DOUBLING THE
SAME," to be as follows:-
Our Invention relates, firstly, to that method of arresting the winding

page_text: when an end breaks, for which Letters Patent were granted to us dated
24th June 1873, No. 2201, and our present improvement is designed to
prevent the blades from wearing the drums. For this purpose we cause
to bobbin to press against the drum by a weight as usual, but we also
adapt thereto another and heavier weight, which when at liberty to act
causes the bobbin to pass away from the drum. During the winding
this heavier weight is supported by a stop, but when an end breaks a
filling piece falls between the said stop and a vibrating bar, and the stop
being thus driven away the heavier weight is at liberty to act and
prevent the bobbin from pressing the blades upon the drum. This
arrangement may be used without the above-mentioned blades, as the
removal of the bobbin from the drum necessarily arrests it motion, but
the blades serve as a preparatory break.
Another arrangement having the above-mentioned object is as
follows: When an end breaks the guide which was supported by it
falls as usual, but according to our Invention it arrives in contact with a
rod connected to the stop piece of the heavier bobbin weight above
mentioned, and the drawing upward of the stopping blade by the drum
and bobbin, causes the said rod to throw off the support of the weight,
which is then allowed to act as above described.
Another part of our Invention has for its object the stopping of the
winding when the bobbin is full, or when any desired quantity of
material has been wound thereon. For this purpose we employ the
heavier bobbin weight above described, but prevent it from acting until
the required time by a stop. As the bobbin becomes filled it moves, as
is well known, from the surface drum, and when such motion has taken
place to a determined extent the arm which rests on the stop becomes
clear of it and the weight is then at liberty to act. The stop is made
adjustable to allow more or less material to be wound before the weight
comes into action. The stop for this part of our Invention may be that
above described or adapted for this purpose only.

filed by the said Joseph Stubbs and John Corrigan in the Great Seal
Patent Office on the 26th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, 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-sixth day of November, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth 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 exe-
cutors, 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 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, firstly, to that method of arresting the winding
when an end breaks for which Letters Patent, were granted to us dated

page_text: Twenty-fourth June, One thousand eight hnndred and seventy-three,
No. 2201, and our present improvement is designed to prevent the
blades from wearing the drums. For this purpose we cause the bobbin
to press against the drum as usual by a weight, but we also connect
therewith a heavier weight, which when at liberty to act (owing to the
breaking of a thread) causes the bobbin to pass away from the drum.
In the accompanying Drawing, Fig. 1 represents in cross section a
portion of a winding frame with our improvement adapted; Fig. 2 is a
plan view; Fig. 3, a detached view of certain of the parts taken at right
angles to Fig. 1; and Figs. 4 and 5, views representing a modification of
the mechanism which governs the motion of those parts constituting our
Invention, and which said Figs. 4 and 5 will be referred to after we
have described the arrangement shown in the general views. The plan
view Fig. 2 shews one head only, but that of course is repeated for any
width of machine that may be desired.
เ
At a is the drum of one side of the machine, and at b is the bobbin
mounted in the cradle c, which turns upon the contre d carried by the
bracket e. To the cradle c is attached a lever provided with a
weight g, by which means the bobbin b is pressed against the drum, but
allowed to turn outward as it becomes filled as usual. At his the hand
or "setting on" lever, capable of being turned on a centre i carried by
the cradle c, and this hand lever has an extended part k, the outward
end of which rests (according to the positions of the parts shewn in the
Drawing) upon a stop piece upon the extended part of the lever,
and projecting from the face thereof is a part * situate in the same
plane as the portion m of the cradle c, but formed at an angle as shewn
by the dotted linen in Fig. 1, so that during the winding the cradle is
able to move outward as the bobbin fills without arriving in contact
with the part 1*. Connected with the lever k is a wire or chain o, which
after passing over a guide pulley p carries a weight q, which owing to its
own bulk or to the leverage which it possesses is superior in effect, when
at liberty to act, to the first-mentioned weight g, but according to the
positions shewn it cannot cause the lever k to turn upon its centre, the
outward end thereof being situate on the stop 7. This stop is formed
upon a frame » which is capable of turning upon a centres, and it is
borne in an inward direction by a weighted lever t, the extent of which

page_text: motion however being regulated by a set screw u; and at v is a bent wire
fixed at either end to the lower part of the frame 1. At wo are the
thread guides attached to the bars a, cach of which carries a blade y, as
described in the Specification of our former Patent aforesaid.
•
The Operation is as follows:-According to the positions of the parts
as shewn the winding is proceeding as usual, the cradle moving outward
as the bobbin fills, such moving outward being allowed as before
mentioned in consequence of the angular form of the part n as above
described; when an end breaks, the bar x by falling and turning upon its
centre a* elevates the blade, which by being thrust between the bobbin b
and drum a, arrests the winding according to our former Patent aforesaid ;
but this would be attended by a certain amount of damage to the surface
of the drum, and the moving of the bobbin outward now takes place by
the action of the weight 9 and in the following manner:-When the
bar & falls by the breaking of a thread, it arrives in contact with the
bent wire v, simultaneously with which the blade y arrives at the grip of
the bobbin b and drum a, and being thus pulled upward turns the bar x
upon its centre * and forces downward the bent wire v, thus causing
the frame to turn upon its centres and move the stop 7 from under the
lever k. The weight q being now at liberty to act causes the said lever
to turn upon its centre i, and the bottom of the part n then arriving in
contact with the part m of the cradle c, T, the said cradle will be caused
to turn upon its centre d, carrying with it the bobbin 6 away from the
ს
drum a.
The broken end having been pieced as usual and the bobbin
turned to the drum by the lever h, the stop 7 falls back to the position
shewn by means of its lever t, and the operation goes on as
before.
We will now proceed to describe the modification shewn at Figs. 4
and 5, in which the same letters are marked on similar parts to those
above referred to where they occur.
In this instance each of the bars k
has a pendant piece y hanging over a space 2, which on one side is
formed by the frame of the stop 1, and on the other side by bar **
which is mounted on the frame 1 by means of two links 2. To the
bar is imparted a reciprocating motion from any convenient moving
part of the machine, and it therefore possesses a movement similar to one
side of a parallel rule, alternately advancing into the space ≈ and receding

page_text: therefrom. When an end breaks and the bar x falls, it allows the
pendant piece y to fall into the space z, and the reciprocating bar then
advancing forces it against the tail part of the frame and removes the
stop 1 from the lever k, after which the movements above described take
place.
We have hitherto spoken of this part of our Invention as connected
with our former Patent aforesaid, that is to say, in combination with the
blades y, but the said blades might be dispensed with as the turning
back of the cradle and bobbin necessarily stop the winding, only in that
case the arrangement shewn at Figs. 4 and 5 must be employed or its
equivalent, whereby sufficient motive force can be obtained to withdraw
the stop 1, as the weight of the falling bar x would not be sufficient to
force downward the wire v.
Another object of our Invention is to stop the winding, by a self-acting
operation, when the bobbin is full or when any desired quantity of 1
material has been wound thereon, and this we will describe by referring
again to Figs. 1, 2, and 3. The bobbin, as is well known, moves outward
as it becomes filled, the cradle c of course moving with it, and con-
sequently, as above described, the lever k slides upon the stop 6; but we
have hitherto supposed that the said stop is so situate with regard to 2
the lever that the said lever is always on it, excepting when a thread
breaks, but to accomplish the cessation of winding when any desired
quantity of material has accumulated on the bobbin we so arrange the
relative positions of the two parts at starting that when the required size
of bobbin has been attained the lever k will pass from the stop / and by 2
falling will arrest the winding as above described. These relative.
positions of the two parts may be varied by making the end of the
lever on the stop adjustable, and for the latter arrangement we
employ a set screw u which bears against the frame », and by adjusting
this the stop may be caused to turn inward or outward upon its a
centre.
Having this described and ascertained the nature of our said
Invention, and the manner in which the same is to be performed, we
desire it to be understood that we claim as secured to us under the above
in part recited Letters Patent, and for the purposes above set forth, the 3
employment of the heavier weight or its equivalent, as for instance a

page_text: spring, controlled in its action by a stop which ceases to act when a
thread breaks or when the bobbin has received a desired amount of
material.
In witness whereof, I, the said Joseph Stubbs, have hereunto set
my hand and seal, this Twenty-fifth day of May, in the year of our
Lord One thousand eight hundred and seventy-five.
JOSEPH STUBBS. (L.S.)
