Improvements in or Applicable to Machinery for Winding and
Doubling Yarns or Threads.
I SAMUEL BROOKS of Union Iron Works, West Gorton, near Manchester in the
County of Lancaster, Machine Maker do hereby declare the nature of the said
Invention for 'IMPROVEMENTS IN OR APPLICABLE TO MACHINERY FOR WINDING
AND DOUBLING YARNS OR THREADS, to be as follows:-
"
My invention relates to what are termed split drum winding machines the
subject of Letters Patent Numbered 2196, dated the 10th day of May 1882 and of
Letters Patent Numbered 5532 dated the 27th day of November 1883, both granted
to Henry Cheetham Hill and Henry Hill Brown, and my invention consists in
combining with such split drum winding mechanism, especially that described in
the specification of the said Letters Patent No 5532-1882, combinations and
arrangements of mechanism for stopping the rotation of the split drum and thus
the winding of the threads when one or more threads break or are absent-I prefer
to arrange the split drum so as to be rotated by friction pulleys, so that the drum
or pulleys on its axis may be lifted or moved out of contact with the driving
pulley or pulleys when it is to be stopped or so that the frictional driving pulley
is brought in and out of contact with the slit drum pulley or pulleys and I do this
by arranging levers, which will be latched in a position to hold the frictional
pulleys in gear when winding, and then detector mechanism of any well known
or similar arrangement, acted upon by a rotary ratchet shaft, will knock off the
latch or catch and allow a weight lever to descend and bring the frictional gear
out of contact, and against a brake to stop the rotation of the split drum when
a thread breaks or is absent.
According to another modification of my invention, the threads pass from cops
or bobbins over a bar, through the eyes of balanced detector wires having their
fulcrums on a lever, which lever has its fulcrum on the framing, this lever has an
arm jointed to it the end of which is a thin blade, that will come when the arm is
lifted between a friction pulley intermediate between the friction driving pulley
and a pulley on the split drum and thus stop its rotation. The intermediate pulley
is mounted on a lever or frame on a stud on the framing and is pulled against the
two pulleys with which it gears by a weight or spring.

page_text: The said arm is lifted when one of the detector wires moves in consequence of
the breakage or absence of a thread or threads when the ratchet or its equivalent
on a rotary shaft lifts the lever carrying the detector wires, and thus stops the
winding.
The threads pass from the eyes of the said detector wires or levers over a pulley
and then down under another pulley and then to the split drum and on to the
bobbin or spool.
According to another arrangement and modification a pulley or pulleys are
placed on the axis of the split drum to be driven by a pulley or pulleys on a shaft
below, and the bearings of the shaft for the split drum, are carried on a frame
having its fulcrum on a 'rod, so that by lifting this frame the pulley or pulleys on
the split drum are lifted out of contact with the driving pulleys to stop it and
brought in contact with a fixed brake.
The thin plate guiding edge between the bobbin being wound, and a split drum
is or may be mounted on the frame carrying the axis of the split drum so that both
will lift or move together.
The frame carrying the axis of the split drum is actuated by a weight lever,
when a thread breaks which weight lever is released, by the action of the detector
mechanism which may be of any well known arrangement and construction or
similar thereto..

I SAMUEL BROOKS of Union Iron Works, West Gorton near Manchester, in the
County of Lancaster, Machine Maker do hereby declare the nature of this
invention and in..what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My invention relates to what are termed split drum winding machines the
subject of Letters Patent Numbered 2196 dated the 10th day of May 1882 and of
Letters Patent Numbered 5532 dated the 27th day of November 1883, both granted
to Henry Cheetham Hill and Henry Hill Brown, and my invention consists in
combining with such split drum winding mechanism especially that described in
the Specification of the said Letters Patent N° 5532-1882, combinations and
arrangements of mechanism for stopping the rotation of the split drum and thus
the winding of the threads when one or more threads break or are absent.
The manner in which I prefer to carry my invention into effect is illustrated by
fig. 1 a front elevation and fig. 2 a transverse sectional elevation, showing so much
of the parts of one head of a doubling and winding machine as will be necessary
for explaining my invention.
Fig. 3 is a sectional elevation taken in the same plane as fig. 2 and showing some
of the parts in that figure, detached and upon an enlarged scale.
a is a beam passing from end to end lengthway of the machine, and carried on
suitable intermediate and end frames.
b is a creel board also passing from end to end of the frame being carried on
projections or brackets from the intermediate and end frames.
This creel board b has brackets b' secured to it to carry a rod b' upon which
rod brackets b³ are secured at any desired angle by a set screw.
The brackets 63 have holes for the cop skewers b' as shown.
This creel arrangement is an ordinary one and any ordinary creel is or may be
used and when the yarn to be wound and doubled is to be drawn from bobbins or
hanks upon swifts any suitable creels are employed for holding the bobbins or
swifts.
c is a front protecting board also passing lengthway of the machine from end to
end and carried on projections or brackets from the intermediate and end frames-
This board c has a thin plate c¹ attached to it with a slit for each thread being
doubled and wound to pass through, and above the edge of the board c another
board is secured passing from end to end of the machine which board is curved
on its upper surface and covered with flannel or other suitable material to give the
required friction to the threads passing over it.
d is a metal rail; e and fare rods, all of which pass from end to end of the
frame, being carried on projections or brackets on the intermediate and end
frames; g is a rotary shaft passing from end to end of the framing being carried
in bearings in brackets from the intermediate and end frames.

page_text: This shaft g has pulleys at one end for the driving belt or it is driven by a belt
or gearing from the shaft that is driven by the first motion driving belt.
Fig. 2 shows the parts on one side of a machine these parts being duplicated on
the other side of a double sided machine.
his the slit drum which is a drum having a diagonal slit h¹ in one direction for
half its circumference, and in the reverse direction for the other half, the threads
being wound, pass through this slit of the drum and are distributed to and fro on
the bobbin while the peripheral surface of the drum acts to rotate the bobbin to
wind the thread upon it.
The split drum h is made with an axis he passing through its ends and there is
a pulley 3 at each end or side, the axis h² projecting beyond the pulleys ³ on cach
side and are carried in grooves or bearings in a bracket or stand a¹ secured to the
beam a.
Two brackets or stands a¹ are required for each split drum h but each stand a¹
is double so as to carry the end pivots of two adjacent split drums except at the
ends of the frame.
The pulleys h³ of each split drum h are carried and rotate by two pulleys g¹ on
the shaft g.
But here again each pulley g¹ is broad enough for the pulleys ³ of two adjacent
split drums except at the ends of the frame.
The shaft g and split drums h are rotated in the direction shown by the arrows
on the pulleys g¹ and split drum h.
The threads being wound and doubled pass (as shown in dotted line in fig. 2)
from the cops, bobbins or hanks through the slits in the plate c' over the board c
covered with flannel each separate thread through the eye of a detector wire then
up to a pulley then down to another pulley then through the slit h¹ in the
split drum h then against the guiding edge of a plate f¹ and lastly on to the spool or
tube e as split drum winding and doubling machines are more particularly intended
and used for winding thread upon spools without heads, though they may be used
for winding upon bobbins with heads.
The pivots of the pulley are carried upon a bracket from a rail passing from
end to end of the machine which rail (not shown) is secured to the intermediate
and end frames The pivots of the pulleys (7) are as is well understood in doubling
and winding frames, carried from one side of the bracket so that the threads can
be readily and conveniently passed over the pulley 7.
The pivots of the pulley are carried on a bracket secured to the beam a and
the pulley rotates or may rotate on a stud in one side of the bracket or the
pivot is or may be on one side of the pulley and rotate in a bearing in the bracket
or pivots on both sides of the pulley is or may be carried in the bracket.
On the rod f there is a bracket f2 for each split drum, to which a thin stcel
plate f¹is rivetted or secured by screws.
The front edge of this plate f¹ is parallel to the axis of the spool on which the
thread is being wound and is a little longer than the traverse given by the slit in
the slit drum h.
The bracket f³ can be adjusted and secured on the rod f to bring the lower side
of the plate fi clear of the upper side of the split drum h and allow it to lift
slightly when its rotation is stopped as hereinafter described.
The ends of the spindle for the tube or spool e¹ are carried in recesses similar to
those for carrying the ends of the spindles of bobbins in ordinary drum winding
frames Or one end of a small flat spring is secured on one arm of each frame e
the other end of which will give way to allow the end of the spindle to be passed
into the notch for it in the arm and hold it therein until withdrawn by sufficient
force the other end of the spindle entering a hole for it in the other arm of the
frame.

•
The frame e2 is made in two parts to grasp the rod e, the two parts e² and e³
being secured together by a bolt e-The bobbin frame e² is free to oscillate upon
the rod e but is kept from end movement by collars e³ secured on the rod e.

page_text: On the side of each bobbin frame e³ a lever handle e³ is jointed at eª-It is
shaped as shown best in fig. 2.
It has two hook projections which will limit the movement and hold the bobbin
frame at each extreme of its movement.
When the spindle is not held in the bobbin frame c² the upper hook e will,
catch upon the rod f and prevent the bobbin frame from descending lower, and
when the bobbin frame is lifted to its bighest position, the recess formed with the
lower hook e will catch upon the rod fand sustain the bobbin frame, which can
be lowered by pushing back the upper part of the handle e³ and thus releasing the
catch from the rod f the lever handle e then takes the position shown in fig. 2
when the spool is winding.
In the stands a¹ there are fork bearings for the pivots m¹ of a lever m―This
lever has an arm m² above its pivot the upper face of which is or may be covered
with leather so as to come close but not touch one pulley h³ when the split drum
is being driven by the pulley g¹.
The lever m has another branch m³ that passes across the split drum and has an
arm m³ for a brake surface for the pulley ³ on the other side of the split drum, as
above described.
The branch m³ from the lever has also a pivot m¹ from it to rest in the fork in
the other stand a¹ and thus the fork in each stand acts for the pivots m¹ of
adjacent levers m.
The main lower arm of the lever m descends and is curved as shown to give
clear space for the hand of the attendant when passing the threads under the lower
pulley .
Then the arm of the lever m passes horizontally and through a slit for it on the
front covering board c the extreine end m* of the lever forming a bandle.
It is the weight of this horizontal portion of the lever m and that of an
additional weight m' which is or may be suspended upon it as illustrated that
when released descends and causes the brake surfaces or arms m² to come against
and lift the pulleys h³ from the driving pulleys gl and at the same time the brake
surfaces arrest the rotary momentuin of the split drum.
This lever m or its equivalent is held up when the winding is going on by any
suitable detector and stop mechanism-That which I have illustrated consists of a
bracket d secured to the rail d (there is one bracket d for each head)-This
bracket d has forks to carry pivots formed at each end of an oscillating plate k²
the pivots being formed in projections from the plate k².
The plate has grooves in projections for the detector wires to work up
and down in, and the lower end of the wire is bent in the loop form which passes
in grooves in the lower projection ³ and this loop and the grooves in the pro-
jection limit its rise and fall and the wires & are kept in their places by a thin
plate secured in notches at the ends of the oscillating plate k².
From the oscillating plate there is a projection that carries a pin ko that rests
against the edge of a stepped plate or lever k having its fulcrum d* on a bracket d
secured to the rail d, or forming part of the bracket d'.
The weight of the plate k³ causes it to keep the pin against the stepped edge
of the lever 6 and the pin k when in a line directly under or in a vertical line
under the pivots k¹ of the oscillating plate will catch upon a step k and sustain
the lever as shown in fig. 3-but when one or more of the detector wires fall
and come in the way of the rotary ratchet n' (which rotates in the direction shown
by the arrow in fig. 3) the plate 2 is moved to bring the pin k³ from under the
step in the lever which then falls until the other step upon it comes upon
and is sustained by the pin k³.
In its descent the edge of the lever acts upon the pin ko and moves the
oscillating plate further so that the detector wires are clear of the ratchet n¹.
The ratchets n¹ are on a shaft n passing from end to end of the framing rotated
in bearings formed in brackets secured to the intermediate and end frames and
rotated by a belt from the shaft g.

page_text: The lever m, and lever ke are connected by a bracket m³ the lower end of wbich
is secured to the lever m by a bolt passing through a slot in the arm m by which
it can be adjusted.
The upper end of the bracket m has a screw stud ma adjustable in a vertical
slot in it the stud fitting a diagonal slot in the stepped lever . It will thus be
seen that when the parts are in the position shown in figs. 2 and 3 the lever m will
be sustained and the split drum will be rotated but when the oscillating plate / is
acted upon by the ratchet n¹ the lever k is allowed to drop one step, and con-
sequently the lever m also, which lifts the split drum away from its driving
pulleys g and stops its momentum. n³ is a cover or shield attached to the
bracket d¹ to prevent the hand of the attendant from coming in contact with the
ratchet and the yarn from catching and lapping upon the shaft when a thread
breaks.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed -I declare that what
I claim is
