Year: 1875

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 ON TO BOBBINS OR SPOOLS
PREPARATORY TO DOUBLING THE SAME.
"
Sealed the 5th November. 1875, and dated the 8th May 1875.
PROVISIONAL SPECIFICATION left by the said Joseph Stubbs and
John Corrigan at the Office of the Commissioners of Patents, with
their Petition, on the 8th May 1875.
1
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 ON TO BOBBINS OR
SPOOLS PREPARATORY TO DOUBLING THE SAME," to be as follows:-
:―
Our Invention relates to that arrangement of machinery in which
thread wires or guides are used, through which the yarns or threads
pass, and which wires or guides fall upon the breakage of their yarn or

page_text: thread and effect a stoppage of the winding, as for instance, in that
machine for which Letters Patent were granted to us, dated 24th June,
1873, No. 2201.
Our present improvement relates to a method of keeping the wires
or guides up steadily to their level until the yarns or threads have
attained their full tension. For this purpose we use a bar situate above
or below the wires or guides, the situation depending upon which side
of the centres of motion it is situate, and which bar moves upward or
downward, as the case may be, so as to press against the wires or guides
and keep their front ends up and level.
.
We propose to mount the above-mentioned bar upon one end of a
weighted bell-crank lever, the weight thereof causing the said bar to
assume the above-mentioned position until the yarns or threads have
attained their full tension, after which the setting-on lever (or part
connected therewith) on being fixed- turns back the bell-crank lever and
moves the bar from the wires or guides, and they are then at liberty to
turn upon their centres when an end breaks.
Secondly. Our Invention relates to our former Patent aforesaid, and
consists in an arrangement for ensuring a stoppage of the winding by
the blades described in the Specification of the said Patent in case the
surface of the bobbins should be somewhat hollow. For this purpose
we form, a groove or grooves upon the surface drums, and form a
projection upon the blades, which projections slip into the said grooves
and secure the required stoppage.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said Joseph Stubbs and John Corrigan in the Great
Seal Patent Office on the 8th November 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 Eighth day of May, in the year
of our Lord One thousand eight hundred and seventy-five, in the
2

page_text: thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, 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 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, our executors or administrators, by an instru-
ment in writing under their hands and scals, 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 per-
formed, 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 Drawing:-
Our Invention relates to that arrangement of machinery in which
thread wires or guides are used, and through which the yarns or threads
pass, and which' wires or guides fall upon the breakage of their yarn or
thread and effect a stoppage of the winding, as for instance, in that
machine for which Letters Patent were granted to us, dated Twenty-
fourth June, One thousand eight hundred and seventy-three, No. 2201.
Our present improvement relates to a method of keeping the wires or
guides up steadily to the level until the yarns or threads have attained
their proper tension.
Secondly. Our Invention relates to our former Patent aforesaid, and
consists in an arrangement for ensuring the stoppage of the winding by
the blades described in the Specification of the said Patent in case the
surface of the bobbin should be somewhat hollow.

page_text: In the accompanying Drawing Fig. 1 is a partial transverse section of
a winding machine; Fig. 2, a side view of portions of the same; and
Fig. 3 and 4 are respectively plan and front views of certain of the parts.
The several Figs. represent a machine constructed after the manner
of that for which Letters Patent were granted to us, dated November
26th, One thousand eight hundred and seventy-four, No. 4066; and
also according to our former Patent of Twenty-fourth June, One thousand
eight hundred and seventy-three, above referred to, but with the im-
provements which we now claimed added thereto.
At 1 is the surface drum, caused to revolve as usual, and giving
motion to the ordinary bobbin 2, upon which the yarns or threads
shewn by the blue colour are wound, such yarns or threads passing
through the wires or guides 3, and by their tension preventing the bars 4
from turning upon their centres 5 until a yarn or thread breaks, but
when such breakage does occur then the blade 6 belonging to its guide 3
is thrust between the surface drum 1 and bobbin 2, the detailed operation
being fully described in the Specification of our former Patent first
referred to. At 7 is the frame, which carries the bobbin, and which is
capable of turning upon the centre 8, and at 9 is the setting-on handle,
also turning upon the same centre, an extension 10 of such handle
resting (according to the position shewn) upon a stop 11, against which
it is drawn by the weight 12, which exerts a greater power than the
other weight 13. When a yarn or thread breaks the bar 4 by dropping
falls against the bent wire 14, which is attached to a lever extending
from the centre of motion 15 of the stop 11, which is thus caused to
turn outward, so as to allow the part 10 to move downward, and then
the frame which carries the bobbin also turns upon its centre away
from the drum 1. When the broken yarn or thread has been pieced
the attendant turns the handle 9 so as to place the part 10 again on the
stop 11, and the bobbin is then in contact with the drum 1.
So far the construction, and operation of the parts are the same as in
our former Patent of November 26th, One thousand eight hundred and
seventy-four, above referred to, and we have merely recapitulated the
general character of the movements here in order to clearly connect our
present improvements, referring to the Specification of our said former
Patent for the details thereof, and we now proceed to describe our said
present Invention.

page_text: It has been seen that when a yarn or thread breaks its respective
bar 4 falls, and the end has to be pieced, during which time the drum 1
ceases to act upon the bobbin 2, and it sometimes happens that when
the winding again takes place there are some of the yarns or threads so
'slack as to allow their respective bars 4 to fall, more or less. When this
condition exists to a certain extent the blade or blades 6 are brought
near to the junction of the bobbin 2 and drum 1, and being then drawn
in the winding is unnecessarily stopped, also the said bars 4 not being
held in proper tension they are caused to vibrate vertically, and it is to
avoid these inconveniences that this part of our present Invention is
designed.
At 16 is an arm capable of turning upon a fixed centre 17, and
carrying at one end a weight 18, and at the other a bent wire 19
projecting under the bars 4 of one head of the machine. Upon the
weight 18 is an incline 20, beneath which is a pin 21 projecting from
the lever 9.
.
When a yarn or thread breaks, and by the operations above alluded
to, the lever 9 turns upon its centre 8, the pin 21 of course passes
downward away from the incline 20, and the weight 18 being then free
to move turns upon its centre 17, and turns upward the bent wire 19,
which by arriving in contact with the bar 4 belonging to the broken
yarn or thread, and with others which may have been allowed to drop
through slackness of their respective yarns or threads, brings all of the
said bars to one level, and prevents them from vibrating. When the
broken yarn or thread has been pieced the attendant as usual turns
the setting-on lever, and just as the drum 1 begins to wind the pin 21
arrives in contact with the incline 20, thereby causing the arm 16 to
turn upon its centre and move downward the bent wire 19 into the
position shewn in the Drawing.
The effect of these operations has been that the bars 4 have been kept.
upward in a steady position, and that the slack of the yarns or threads
have been taken up before the bent wire has sufficiently let the bars 4
down to allow any of the said bars to thrust its blade 6 between the
bobbin and the drum.
The bent wire 19 or its equivalent might of course act on the upper
edges of the bars 4 by placing it on the other side of the centre of
motion of the said bars. At 26 is a weighted lever carrying a pin 27,

page_text: which keeps the levers 4 in their correct positions during the working of
the machine. 28 is an adjustable stop for preventing any number
of bars 4 from acting according to the number of threads to be wound.
The second part of our Invention is shewn at Fig. 1, and more
particularly upon a larger scale, Figs. 5, 6.
At 6 is the blade, which as before alluded to is thrust between the
bobbin and the drum when a breakage takes place. This blade we form
with an indentation 22, which causes a projecting part 23 on the other
side of the said blade; or a projection may be formed in any other
manner. Upon the drum 1 we form longitudinal grooves 24, and when
the said blade is thrust upward the first groove that arrives in the
proper position takes hold of the projecting part 23 and ensures the
carrying forward of the blade sufficiently to stop the winding, by which
means a wearing of the drum or an inequality from any other cause
does not interfere with the operation of the stopping motion.
In order to assist the blade in being drawn forward we serrate the
surface thereof, as at 25.
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,-
Firstly. The use of the bent wire 19 or its equivalent acting sub-
stantially as described.
Secondly. Forming a projecting part as at 23 upon the blade 6, and
grooving the drum as at 24.
In witness whereof, we, the said Joseph Stubbs and John Corrigan,
have hereunto set our hands and seals, this Sixth day of
November, in the year of our Lord One thousand eight hundred
and seventy-five.
