We, THOMAS GLEN COATS of Ferguslie Thread Works, Paisley, in the County of
Renfrew, North Britain, Thread Manufacturer, and THOMAS WATSON, of the same
place, Mechanic, do hereby declare the nature of our said Invention for IMPROVE-
MENTS IN MACHINERY FOR WINDING THREAD INTO BALLS OR UPON SPOOLS OR
BOBBINS "
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
Our said Invention has for its object to improve the gearing and other parts of
machinery for winding thread into balls or upon spools or bobbins. Our improve-
ments are shown on two accompanying Sheets of explanatory Drawings, Figures, 1,
and 2, being end and front elevations, Figure, 3, a plan, Figure, 4, an elevation of
the end opposite to that shown in Figure, 1, and Figuro, 5, a sectional plan of
some parts shown in Figure, 4. In these Drawings the same reference numerals
are used to mark the same or like parts wherever they are repeate 1. Parts not
particularly described or referred to in the following description are to be
understood as being arranged or constructed as in existing machines or as described
in a Specification accompanying another application for Letters Patent of the same
date and by the same applicants.
The machine shown in the Drawings is a balling machine or machine for
winding thread into balls upon tapered bosses or cores, 3, off which the balls are
taken when wound; but some of the improvements are also applicable to machines
for winding thread upon spools or bobbins.
The fast and loose pulleys, 31, for the belt by which the machine is driven are
on a first-motion shaft, 12, which has on it near the end furthest from the pulleys, 31,
a pinion, 32, gearing with a spurwheel, 33, turning, on a stud.
From this spur-
wheel, 33, motion is transmitted through a pair of intermediate wheels, 34, on one
tubular spindle or fixed together, to a spurwheel, 35, fast on a shaft, 29, herein-
after termed the measuring shaft, and having fast on it measuring pulleys, 24, for
the several threads. The intermediate wheels, 34, are changeable and carried on a
stud on an adjustable bracket, to allow of the speed relation of the measuring
shaft, 29, to the first-motion shaft, 12, being changed when required. The various
gearing wheels are indicated by dotted circles in Figure, 1. On the measuring
ahaft, 29, there is centered or hung an arm or bracket, 36, carrying an inclined

page_text: shaft, 37, geared by bevil wheels, 38, at its upper end to the measuring shaft, 29,
and having a worm, 39, on its lower end. This worm, 39, gears with a worm-
wheel, 40, on a shaft, 41, which turns once for each ball that is wound and which
carries the usual cams, 42, 43, for effecting the various usual changes of action
taking place during the winding of a ball. If the worm, 39, is a single threaded
one each tooth of the wheel, 40, will correspond to one turn of the measuring
haft, 29, or to one yarn of thread if the measuring pulleys, 24, are a yard in
circumference, so that the number of yards wound on a ball will in that case be
equal to the number of teeth in the wheel, 40. The parts are arranged so that the
wheel, 40, may be easily changed for a wheel of different size; and the arm, 36,
carrying the inclined worm shaft, 37, can be adjusted to suit a wheel, 40, of any
size between certain limits, the arm being formed with an arc-shaped slot, 45, to
admit of its being fixed in different positions to a bracket, 46, forming part of
the framing. The wheels, 40, may be of sizes ranging from 30 to 200 teeth or
yards; and for quantities greater than 200 yards a slower motion is provided and
38 derived more directly from the first-motion shaft, 12. An arm, 47, is centered
or hung on or concentrically with the shaft, 12, and carries an inclined shaft, 48,
driven by means of a worm wheel, 49, at its upper end in gear with a worm, 50,
on the shaft, 12, and having at its lower end a worm, 51, which gears with the
wheel, 40. The arm, 47, is adjustable upon a slotted bracket, 52, forming part of
the framing, to suit wheels, 40, of different sizes, or for being fixed entirely out of
gear when the wheel, 40, is being driven by the other worm, 39.
On a part of the first-motion shaft, 12, near the pulleys, 31, there is. a pinion, 53,
having helical or oblique teeth, which drives a spurwheel, 54, having similar teeth,
on a shaft, 55, which is at right angles to and below the first-motion shaft, and
which transmits the motions for driving the spindles carrying the bosses or cores, 3,
on which the balls are formed. As is usual in many existing balling machines two
rates of speed are provided for, the shaft, 55, having on it two differently sized
spurwheels, 56, 57, which through intermediate wheels, 58, 59, carried by studs,
drive spurwheels, 60, 61, which are loose on an upper shaft, 62. The upper
wheels, 60, 61, have clutch disks, 63, 64, fixed to them, and between them there is
a clutch, 65, fitted to the shaft with a groove and feather for putting the shaft into
gear with either wheel, 60, or 61, this clutch being moved by a lever, 66. This
clutch lever, 66, is moved by a simple device contrived to lock it in its extreme
positions in such manner as to prevent the clutch from getting out of gear
improperly through vibration or other causes. The shifting of the clutch lever, 66,
is effected by a horizontally sliding bar, 67, formed with a slot, 68, through which
there passes a pin adjustably fixed to the bottom end of the clutch lever, 66. This
slot, 68, has a middle curved part with the ends straight and parallel with the bar;
and when the bar, 67, is moved along, the middle curved part shifts the clutch
lever, 66, and then the straight part at either end keeps it steadily in position.
The bar, 67, is moved by means of a pin on it acted on by a lever, 69, which is
itself acted on at the proper time in one direction by a roller, 70, carried by one, 44,
of the cams on the shaft, 41, being moved back again by a spring, 71, seen in
Figure, 2. The upper shaft, 62, has a bevil pinion, 72, on its front end in gear
with a bevil wheel, 73, on a short spindle which through the usual arrangement of
small spurwheels, 74, drives the horizontal spindle, 75, of the oblique frame, 76,
this spindle, 75, by bevil wheels, 77, driving the spindles of the bosses or cores, 3,
on which the balls are formed,
We do not restrict ourselves to the precise details herein before described or
shown in the accompanying Drawings provided that the distinctive features of our
Invention are retained; these being-the combination consisting of the measuring
shaft, 29, having its measuring pulleys, 24, with the arm, 36, carrying the shaft, 37,
and adjustable to suit different sizes of wheel, 40, on the cam shaft, 41; the
combination consisting of the worm, 50, on the first-motion shaft, 12, the arm, 47,
carrying the shaft, 48, driven by the worm, 50, and adjustable to suit different
sizes of wheel, 40, on the cam shaft, 41; and the combination of parts for moving

page_text: the clutch lever, 66, and especially the slot, 68, shaped to lock the lever in its
extreme positions.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
:-
1. The combination consisting of the measuring shaft, 29, having its measuring
pulleys, 24, with the arm, 36, carrying the shaft, 37, and adjustable to suit different
sizes of wheel, 40, on the cam shaft, 41, substantially as and for the purposes
herein before described.
2. The combination consisting of the worm, 50, on the first-motion shaft, 12, the
arm, 47, carrying the shaft, 48, driven by the worm 50, and adjustable to suit
different sizes of wheel, 40, on the cam shaft, 41, substantially as and for the
purposes herein before described.
3. The combination of parts for moving the clutch lever, 66, and especially the
slot, 68, shaped to lock the lever in its extreme positions as herein before described.
