A communication from abroad by David Grandy, junior, and Emile
Queulain, Manufacturers, both of 29, Boulevart St. Martin, Paris.
I, WILLIAM CLARK, of 58, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN APPARATUS FOR SPOOLING AND COPPING THREADS OR YARNS,"
to be as follows:-
This Invention relates to apparatus for spooling or winding threads or
yarns.
1st, the spindle is inclined instead of being placed in a vertical or horizontal
position as hitherto in all machines of this nature, thereby aiding considerably
in the formation of the spool and the winding off the bobbin.
2ndly, the simplicity of the mechanism enables these improved machines to
be produced at much less cost than those on the old system, at the same time
requiring less repairs and expense of maintainance.
3rdly, this system facilitates the formation of a spool or cop with or without
a core; in the latter case the thread is wound on the machine spindle instead
of on the spool tube by a movement which permits of the thread being crossed,
it also imparts solidity to the spool, and facilitates its supply to the shuttle,

page_text: while a greatly superior selvedge as regards regularity may be made by the
use thereof than has been produced hitherto in any kind of fabric.
4thly, the spindle when in motion stops of itself by a recoil movement
which forces the band on the loose pulley when the spool is complete.
This movement, which is effected in a precise but simple manner has long been
desired, but heretofore has failed to be produced. This improvement will be
of great service as the operative has only to watch for the stopping of the
spindle in order to remove the full spool and replace it by an empty one,
while in ordinary it is necessary to stop the full spool in time, in order to
prevent waste.
5thly, in the ordinary arrangement of the spools an operative cannot attend
to more than eight or ten spindles, while on this improved system double that
number can be readily managed; thus is obtained a saving in manipulation and
in maintainance, a gain in the expense of the apparatus, greater production
and improvement in the work. From the simplicity of its motion also less
power is required, while it will form a spool either from a reel or spinning
bobbin being constructed so as to receive the thread either in banks or bobbins.
This Invention is illustrated in the accompanying Drawing which shows a
sectional side elevation of one side of the apparatus. The machine is double,
that is to say, the spindles are disposed on each side and receive motion from
the same shaft. a, framing of the machine; b, b, inclined surfaces disposed at
the upper part on each side of the framing, each being provided with a number
of bearings c in which the spindles turn; d, driving shaft of the machine; e,
hollow sockets, square in their interior, turning in bearings c, and provided with
fast and loose pullies f and g; h, spindles fitting in sockets e, and turning there-
with they being made of square section for a certain length for the purpose; i,
wood cop tube without stem, adjusted on spindle h, and bearing against collar
j on the said spindle; k, cone, carried on the framing, serving to receive the
lower end of the cop tube i, the cone is also provided with an opening for
the passage of the spindle during the spooling operation; l, drum, keyed on the
driving shaft, and transmitting rotary motion to the sockets by which the.
spindles are driven; m, rod, having a sliding motion parallel to the spindles in
the bearings n, n, this rod is connected to the spindle at one end by a fork o,
and thus moves with it; p, tappet, fixed to stem m, for producing a sliding
motion in a rod r at the moment the spindle has reached the end of its course,
that is, when full; this rod r carries a clutch & which serves to transfer the
driving strap t from the fast to the loose pulley; u, lever osciliating at v, the
one end being provided with a counterbalance x while the other is received
in a slot made in r, serving to keep this rod in one or other of the

page_text: positions shown, in order that the strap shall not slip from one pulley to the
other except by the action of the tappet before mentioned; y, reel or winder
carrying the thread for forming the cops; z, thread guides mounted at suitable
points on shafts 1, 1, running across the machine, receiving oscillating motion
from an eccentric 2, keyed on the driving shaft by means of connecting
rod 3 and lever 4; the whole being arranged as described the action of the
apparatus is as follows:-At the commencement of the operation all the cops
are placed in cones k, which cops rise, as also the spindles, by the act of
winding the thread, when the cop has become full it is immediately disengaged
as before described.
The Invention thus consists of an improved apparatus for spooling weft
threads or yarns, its chief features being,―
1st, the arrangement of the spindles in an inclined position whereby to
dispense with the weights ordinarily used for producing a suitable pressure of
the thread in the formation of the cops, this pressure being obtained by the
weight of the spindle and its accessory parts by reason of their inclined
position.
2ndly, the instant discharge of the spool immediately it has completed its
