JOHN COMBE, of 11, Trinity Crescent, Trinity, in the County of Edinburgh.
"IMPROVEMENTS IN MACHINERY FOR WINDING COps."
My Invention consists of a variety of points of deviation from the arrangement
of parts, as specified in my previous Patent of July 2nd 1873, greatly simplifying
and reducing the cost of making cop winding machines.
I place the spindles horizontally on a level with a central driving shaft, which
shaft also carries the heart wheels which give motion to the traverse bars. I make the
cups and the sockets which carry the spindle wheels in one casting, which is planted
on a horizontal rail extending the length of the machine. This casting is made
with a space between the socket and the cup sufficient to permit the play of the
brass bush in two parts, which embrace the spindle when the spindle is pushed
inwards to be put in motion, or is projected outwards and stopped for piecening a
a broken end, or for doffing a cop.
The portion of this casting from which the small end of the cup projects is made
with a lug projecting upwards, which receives one end of a small spindle above and
parallel with the winding spindle, and the other end of this small spindle is received
in the lower portion of a transverse lug projecting upwards from the socket which
carries the spindle wheel. On this small spindle a small casting with two horns
projecting downwards and embracing and holding together the two halves of the
brass bush which embraces the spindle is made to slide in and out, which, it is
evident from the arrangement described, it must do simultaneously with the
spindle, and vice versa. This small sliding casting is provided on its upper part at
[Price 4d1

page_text: one side with a small piece of steel on the side next the cup, and this piece of
steel is caught and retained by a steel hook from which a round stem projects
transversely at right angles, and which round stem is received in a socket drilled
for it in the upper portion of the transverse lug cast on the upper part of the
spindle wheel socket.
The round stem of the steel hook projects through the transverse socket, and on
its projecting end is fixed a small triple armed lever, one arm sloping outwards and
upwards, and the other two arms extending horizontally, one outwards and one
inwards.
The tension levers are made to play on spindles carried by small castings, which
are screwed to a horizontal cast-iron plate, which extends along and forms the
middle portion of the covering plates of the machine.
From the right side of the tension lever projects a small round pin in which two
grooves are turned, which receive and retain the hook and the loop of two wires,
the wire with the loop being attached to that arm of the triple armed lever which
projects inwards, and the wire with the hook being attached to the arm of the
triple armed lever which projects in a sloping direction upwards and outwards.
By the arrangement described when the tension lever is liberated from the pull
of the yarn being wound by its breaking, or by the bobbin wound from being
emptied and recoils upward, the wire with the hook will have its hook pulled
upwards by the pin projecting from the tension lever, and so pulling the sloping
arm of the triple armed lever upwards and backwards will lift the steel hook clear
of the steel catch attached to the small casting which slides on the small spindle
placed above and parallel to the winding spindle. This small sliding casting is
provided with two small lugs, one at each side, drilled to receive the hooks of two
small spiral springs, the other ends of which spiral springs are also provided with
hooks which hook into two small lugs cast one on each side of the cup at its widest
part, and which lugs are drilled to receive the hooks of the spiral springs, so that
when the steel catch on the small sliding casting is released from the steel hook
the contraction of the spiral springs will pull the sliding casting, and with it the
spindle, outwards to the extent to which the space in the sliding casting will allow.
When the tension lever by entanglement of the yarn being wound is pulled down-
wards to the extent that the lower part of the loop of the looped wire is pressed
downwards by the projecting pin of the tension lever the steel hook will in a like
manner be raised by the looped wire depressing the arm of the triple armed lever
to which the looped wire is attached, which projects horizontally inwards.
The spring top which gives the pressure to the cop being wound is made in the
form of a cylindrical block, which is pushed inwards by the hand until the steel
hook catches the steel catch on the small sliding casting by which the spindle is
set in motion and kept in action until the steel hook being again lifted releases the
steel catch on the sliding casting, and so stops the spindle, as above described.
On the lower part of the cup at its widest end a lug is cast, projecting down-
wards, which lug receives a round pin which carries a lever, one end of which
projects outwards directly under the cop, and at its outer extremity is turned
upwards at an angle of 45 degrees to such an extent as that it is depressed by the
sliding outward of the cylindrical block when the cop is wound to its proper length.
The other end of this lever curving slightly upwards, and deflected to the right, pro-
jects inwards, and is connected by a wire link to that arm of the triple armed lever
which projects horizontally outwards, and thus the depressing of the outer
extremity of the lever last described by the cylindrical block will also raise the
steel hook, release the steel catch, and liberate and stop the spindle. The bobbins
containing the yarn of which cops are wound are placed below the cops on sockets
revolving on spindles inclined at an angle of about 15 degrees above the horizontal,
and the weight which drags the bobbin is provided with an arm which projects
inwards under the rail previously described, and the drag weight is made moveable
on a round pin, so placed that when the arm projecting inwards is depressed the
drag weight will be raised, and the bobbin released from the drag of the weight.

page_text: The pin which projects from the tension lever is provided with a brass nut, which
is prolonged on the left side of the tension lever, and drilled so as to receive and
retain the end of a wire, the other end of which passes downwards through a
hole in the rail previously described, and strikes on the end of the projecting arm
of the drag weight so that the depressing of the tension lever pressing the L
ended wire downwards that wire presses down the projecting arm of the drag
weight, and so releases from the drag of the weight the bobbin from which the cop
is being wound.
On the horizontal cast-iron plate, previously described, are screwed small cast-
iron brackets placed transversely, each end of which carries a pin on which
oscillates a lever formed of sheet steel, which passes downward through a notch
cut in the side of the horizontal plate.
Each of these levers carries a roller, and these rollers are held in contact with
the heart wheel by a link which connects the ends of the two levers, which are
prolonged downwards so as to be in the line of the slope of the upper side of the
cups, and a slip of sheet steel is made to connect the lower end of each lever with
its respective traverse bar, so that the oscillation of the sheet steel levers under
the action of the heart wheel transmits the requisite traverse motion to the
traverse bars.
Adjoining the central horizontal plate are two narrower plate, which are made
moveable, resting on ledges cast on the framing of the machine, and retained in
their proper positions by pins projecting upwards from these ledges, and taking into
holes in the ends of these narrower horizontal plates, which are made of such a
width that the loop wire plays in a notch cut in the inner side of the narrow plate,
and the hooked wire plays in a notch cut in the edge of a sheet-iron plate bent
in a quadrant, and continued downward perpendicularly, so as to complete the
covering of the machine, and this plate is made removable, so that the working
parts described may be got at to be oiled when required.
In machines for winding from the hank I make the swifts with arms of wood
fixed between central discs of sheet steel notched and bent to embrace the wood
arins, and rivetted together at each arm. One of these discs is blind, and the other
has a central hole in it, which receives a socket which is screwed fast to the
centre of one side of the swift, and this socket receives one end of a double stud
which drops into a slot in the end of a double-armed casting provided with two
horizontal wings, which are screwed fast to the rails on each side of the machine
previously described. One arm of this double-arined casting projects upwards, and
carries two swifts for winding from above, and the other arm projects downwards,
and carries two swifts for winding from below.
The double studs, previously described, are made of larger diameter at the root
end, and are turned with a groove, which receives a staple which is lot into the
end of the socket of the swift, so that when the staple is in its place the socket
is retained on the stud by the staple taking into the groove above described.
The outer ends of the wood arms are provided with double-pronged forks formed
of sheet steel to receive and retain the hanks of yarn to be wound, and one or
more of these double-pronged forks is made with a spring joint, so that it can be
turned down to allow the hank of yarn to be passed into its place, and on this
being accomplished the double-pronged fork is turned out, so that its prongs extend
radially, and retain the hank of yarn in its proper position.
