MACHINERY FOR WINDING THREAD UPON SPOOLS OR BOBBINS
"
This Invention has for its object to improve the construction and action of
certain parts of a well known kind of machinery by means of which thread is
automatically wound upon spools or bobbins.
Each machine of the kind referred to is constructed to operate simultaneously
on a number of spools, the winding spindles being horizontal, and there being a
winding spindle and a back spindle for each spool all in the same line. Below the
spindles there are two horizontal rods, to one of which the winding spindles are
attached, the back spindles being attached to. the other rod, and these two rods
have the necessary movements imparted to them by rotating cams at one end of
the machine. One of the present improvements consists in introducing an
adjustable connection, consisting by preference of a coupling having right-hand and
left-hand screw threads, between the rod to which the back spindles are attached
and the part directly acted on by the cam, the object being to allow of all the
back spindles being simultaneously and uniformly adjusted for different sizes of
spools. Another improvement consists in making the driving clutch or tube on
each driving spindle large enough to take within it the boss usually formed on the
spool end so that the serrated edge of the tube may bear on the part of the spool
end outside of the boss, the object being to prevent thread from winding on the
boss and to allow of the thread being cut more closely against the spool end; which

page_text: result is also further insured by forming a hook-like notch in the knife or cutter.
To allow of the enlarged clutch or driving tube being used without interfering
with the movements of the spindle in the heads or bearings carrying the driving
pinion, the spindle is enlarged throughout its bearing part and instead of being
driven by means of a key or feather formed or fixed on it, it is formed with a
groove in which there engages a key or feather in the tubular bearing piece on
which the driving pinion is placed.
Another improvement consists in applying an automatic feeding device for
supplying the spools successively to the winding spindles, instead of its being
necessary for the attendant worker to place each spool separately in a cradle which
at the proper time presents it to the spindle. In connection with each spindle
there is fitted an inclined shoot capable of holding a dozen or other convenient
number of spools; and the shoot is formed with a fixed or permanent back and
with one fixed side, a second side being provided which is adjustable to suit
different sizes of spools. There is also a narrow covering piece which is attached
to the fixed side of the shoot, and which is adjustable for different sizes of spool;
and this covering piece has its lower end terminating sufficiently above the bottom
of the shoot to allow a single spool to be carried forward at a time. For carrying
each spool forward from the bottom of the shoot to the position where it is taken
hold of by the spindles, there is provided a cradle formed with an angular recess or
seat at its front part and with a plate at its after part extending back from the
top of the angular seat. At the proper times the cradle is moved backwards and
forwards in a rectilinear or curved course its movements being derived from a
suitable cam; and when in its back position the lowermost spool in the shoot drops
into the angular seat, whilst when it moves forward its plate keeps up the
remaining spools.

by the said John Pinkerton Kerr and Thomas Law in the Great Seal Patent
Office on the 14th July 1883.

MACHINERY FOR WINDING THREAD UPON SPOOLS OR BOBBINS
"
IN
Our said Invention has for its object to improve the construction and action of
certain parts of a well known kind of machinery by means of which thread is
automatically wound upon spools or bobbins.
Each machine of the kind referred to is constructed to operate simultaneously
on a number of spools, the winding spindles being horizontal, and there being a
winding spindle and a back spindle for each spool, all in the same line. Below the
spindles there are two horizontal rods, to one of which the winding spindles are
attached, the back spindles being attached to the other rod, and these two rods

page_text: have the necessary movements imparted to them by rotating cams at one end of
the machine. One of our present improvements consists in introducing an
adjustable connection, consisting by preference of a coupling having right-hand
and left-hand screw threads, between the rod to which the back spindles are
attached and the part directly acted on by the cam, the object being to allow of
all the back spindles being simultaneously and uniformly adjusted for different
sizes of spools.
.
Another improvement consists in making the driving clutch or tube on each
driving spindle large enough to take within it the boss or pap on the spool end, so
that the serrated edge of the tube may bear on the part of the spool end outside
of the boss, the object being to prevent thread from winding on the boss, and to
allow of the thread being cut more closely against the spool end; which result is
also further insured by forming a hook like notch in the knife or cutter.
Another improvement consists in applying a new automatic feeding device for
supplying the spools successively to the winding spindles, instead of its being
necessary for the attendant worker to place each spool separately in a cradle which
at the proper time presents it to the spindle.
And in order that our said Invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing our improvements.
Figure, 1, on the accompanying sheet of drawings is a transverse vertical section
and figure, 2, is a partly sectioned front elevation showing as much of a spool
winding machine as is required for explaining our improvements. In these figures
the same reference numerals are used to mark the same or like parts wherever they
are repeated.
Whilst the machine is made for winding a number of spools the parts shown in
the figures appertain to only one spool, and some well known details are omitted
which would render the drawings unnecessarily complex. The winding spindle, 3,
for each spool, 4, is carried in bearings in two vertical plates, 5, 6, which with a
connecting base form a small frame which is fixed on the front longitudinal frame
rail, 7, of the machine. The back spindle, 8, is carried by a bracket, 9, fixed on a
horizontal rod, 10, a similar parallel rod having fast on it a bracket, 11, which
moves the winding spindle, 3 endways as required. At the end of the machine
the rod, 10, is connected to the part through which it receives its endway move-
ments by a link made with a coupling, 12, having right-hand and left-hand screw
threads, and by means of this coupling the several back spindles, 8, can all be
simultaneously and uniformly adjusted for different sizes of spools.
The spool, 4, is of the kind, as shown in figure, 2, having a boss or raised central
part on one end, and the clutch tube, 13, on the winding spindle, 3, is made large
enough for this boss to enter into it as shown. To allow of the enlarged clutch
or driving tube, 13, being used without interfering with the movements of the
winding spindle, 3, in the heads or bearings, 5, 6, the spindle is enlarged throughout
its bearing part, and instead of being driven by means of a key or feather formed
or fixed on it, it is formed with a groove in which there engages a key or
feather, 14, held in a slot in the tubular bearing piece, 15, on which the driving
pinion, 16, is placed. The key, 14, serves not only for making the winding
spindle, 3, turn with the bearing tube, 15, but also for making the latter turn with
the pinion, 16, the key projecting through the tube, 15, into a groove in the eye of
the pinion. To allow of the parts being got into their places a notch is cut in the
bearing in the head or plate, 6, as shown at 17, for the key to pass through when
the tube, 15, is being inserted into the pinion, 16.
Our improved automatic spool feeding device comprises an inclined shoot, 18,
capable of holding a dozen or other convenient number of spools. This shoot is
fixed at its upper end to an upper longitudinal frame rail, 19, and is formed with
a fixed or permanent back, 18, and with one fixed side, 20, a second side, 21, being
provided which is adjustable to suit different sizes of spools. There is also a narrow
covering piece, 22, which is attached to the fixed side, 20, of the shoot and which

page_text: is adjustable for different sizes of spool; and this covering piece, 22, has its lower
end terminating sufficiently above the bottom of the shoot to allow a single spool, 4,
to be carried forward at a time. For carrying each spool, 4, forward from the
bottom of the shoot to the position where it is taken hold of by the spindles, 3, 8,
there is provided a cradle, 24, formed with an angular recess or seat, 25, at its front
part and with a plate, 26, at its after part extending back from the top of the
seat, 25, At the proper times the cradle, 24, is moved backwards and forwards in
a rectilinear course (or it might be in a curved course) its movements being derived
from a suitable cam; and when in its back position the lowermost spool in the
shoot, 18, drops into the angular seat, 25, whilst when it moves forward its
plate, 26, keeps up the remaining spools. The forward part of the cradle, 24, rests
and moves upon a forked guide, 27, and its back end is jointed to a lever, 28, fast
on a rocking shaft, 29, which is acted on by a suitable cam.
The knife, 30, for cutting the thread against the end of the spool, 4, is shown in
figure, 1, and a front view is given at the right-hand side of that figure, showing
the notch for the thread to catch in and thereby render the cutting action more
certain.
Having thus particularly described our said Invention and the manner of
performing the same we have to state that we do not restrict ourselves to the
precise details herein described or delineated but that what we believe to be novel
and original and claim as the Invention secured to us by and in terms of the
herein before in part recited Letters Patent is :-
1. The adjusting of a number of back spindles (8) by means of one right-and-
left screw coupling (12) applied to the rod (10) which works them all, as
herein before described.
2. The improved enlarged clutch or driving tube (13) combined with the
uniform enlargement of the spindle (3) and its bearing tube (15) as hereinbefore
described.
3. The combination of parts constituting the improved automatic feeding device
such parts being arranged and operating substantially as hereinbefore described.
4. The forming of the thread cutting knife with a notch as hereinbefore described
and as shown in the accompanying drawings.
In Witness whereof, we, the said John Pinkerton Kerr, and Thomas Law, have
hereunto set our hands and seals this twelfth day of July in the year of our Lord
One thousand eight hundred and eighty-three
