I, JOHN COMBE, of Claremont, in Headingley, in the Parish of
Leeds, in the County of York, Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR
WINDING COPS FOR WEFT, OR WARF, OR OTHER PURPOSES," to be as follows:-
My Invention consists, firstly, in driving two rows of spindles from one
central shaft carrying driving wheels, each of which gives motion to two
spindle wheels, the two rows of spindles being made either to incline
outwards in a direction coincident with the radius of the driving wheel
and being driven by unskewed bevil wheels, or the two rows of spindles
may be vertical and driven by unskewed driving wheels, each of which
gives motion to two spindle wheels, the teeth of which are skewed in
opposite directions.
My Invention consists, secondly, in making the spindles of cop winders
with two wings, which drop into a groove cut across the top of the
spindle wheel, and in retaining the spindle in this position, and allowing

page_text: the cop to slide upwards on the spindle as it is formed, the requisite
solidity being given to the cop by a weight which rests on it and slides
upwards on the spindle as the cop is formed. A collar is formed on the
spindle immediately above the wings above described, and when the
spindle is in motion it is prevented from rising by a forked arm projecting
from a rod which slides up and down, or adjacent to and parallel with the
spindle, the forked end of this arm pressing on a leather washer soaked
in oil and placed above the collar of the spindle. The lower end of the
sliding rod carries another arm which projects under the low end of the
spindle, and causes the spindle to rise when the sliding rod rises, and vice-
versa, the forked arm pressing on the leather washer above the collar of
the spindle causes the spindle to descend when the sliding rod descends.
The lower arm of the sliding rod is jointed into the horizontal arm of
a bell crank, the other arm of which projects downwards and is acted
on by a spiral spring, so as to cause the sliding rod, and with it the
spindle, to rise by the expansion of the spiral spring, when it is released
by the undoing of a catch which retains the sliding rod from rising.
when it is at the lowest point and the spindle is in motion.
My Invention consists, thirdly, in using an oscillating lever actuated
by a spiral spring, and carrying a roller, so that the yarn by passing
round such roller before being led to the spindle will have an increasing
tension put upon it by the oscillating lever being pulled towards the
spindle. A projecting arm at the lower end of this lever is made to act
on an arm projecting from the catch which retains the spindle from rising,
so that when the yarn breaks the return of the oscillating lever from its :
position under tension will undo the catch, and cause the spindle to stop
in its rotation, and to rise to such an extent as will allow the girl
attending the machine to get at the broken end of the yarn. A similar
projecting arm is also made to undo the catch when the oscillating lever
is pulled to the extreme in the opposite direction by the entanglement
of the yarn in winding from the hank.
My Invention consists, fourthly, in mounting two opposite spindles on
a cast-iron bridge which carries the cups, sockets, for spindle wheels,
sliding rods which raise and lower the spindle, and bell cranks and catches
which act on the sliding rods by which all the parts connected with each
pair of spindles may be fitted truly to each other, and then the cast-iron
bridge with all its apparatus fixed in its place resting at each end on
two ledges formed on the rails on the opposite sides of the machine.

page_text: The top of this cast-iron bridge is formed in a curve concentric with the
driving wheels and carriers, a covering in plate, the curve of which is
continued in two similar plates, one on each side, opening outwards on
hinges at their lower sides. A set of double plummer blocks which carry
the traverse shafts are fixed on the central covering plate, and the
traverse is communicated to the yarn by two small rods carried at intervals
by cast-iron arms keyed fast on the traverse shafts, the yarn being passed
over the outer of these rods and under the one nearest to the cup. In
order to stop the spindle when the cop is formed a small rod is made to
slide in bearings near to and parallel with the spindle, the lower end of
which rod is made to act on an arm projecting from the stopping catch
previously described when an adjustible arm which projects from the
stop rod over the weight which rests on the cop is raised as the cop
is formed. The general arrangement of cop winder described being
very compact both in breadth and height in winding from the hank I
place one row of swifts below and one row above, from which the yarn
passes over guide rods so as to be delivered in the proper direction to suit
the action of the spring tension lever previously described.
In winding from bobbins the spring tension lever is caused to raise a
small spindle which carries the bobbin from which the yarn is wound so
as to lift the bobbin clear of a friction bar on which it rests, and by
which its motion is retarded, and allow it to revolve freely on the pivot
of the spindle.
