IMPROVEMENTS IN APPARATUS CONNECTED WITH RING SPINNING
Year: 1884

page_text: We, THOMAS THORP of Whitefield in the county of Lancaster, Civil Engineer, and
BENJAMIN COOPER of 14 Brown Street Manchester in the County of Lancaster do
hereby declare the nature of our invention for "IMPROVEMENTS IN APPARATUS
CONNECTED WITH RING SPINNING," to be as follows:-
"
The improvements relate to what is known as ring spinning, when the same is
used for the spinning of yarn in cop form upon paper or other tubes, and consist
of certain apparatus which has for object the "doffing" of the cops from the
spindles.
•
To accomplish this, and to effect our improvements, we employ tubes composed
of paper or other suitable substance, which are split in their length, either on one
or two sides, but, by preference on one side, and capable of being opened and put
on to the spindles without sliding the same on to the ends thereof.
If a tube is cut open on one side, and only partially cut through on the other,
the two sides may be opened on a kind of hinge joint, formed by the partial cut.
Or, the hinge may be formed otherwise.
This hinged tube is thus capable of clasping a spindle, and fits at its lower end,
into a tube carrier composed of a small socket placed on the spindle, and which
socket may either be constructed so as to clip the spindle by a spring, or, by pre-
ference, to have the recess for the tube formed somewhat conical, so that by simply
pressing down the tube therein, the requisito grip is obtained.
Underneath this tube carrier is fixed a suitable lifter, attached to a rod or
analagous device. This rod, carrying the lifter, extends to a distance above, corro-
sponding to the distance of motion given, and has fixed at that height a cop rest, in
such form that the operator can, by actuating a lover, or other obvious mechanism,
cause the tube carrier and cop rest to rise, and thus partly lift off the cop on the
spindle. The cop rest may then be allowed to resume its original position, and a
new split tube may be adjusted in the carrier, and upon the spindle. Or the
operation of adjusting the split tube may be performed at any time during the
formation of the cop.

page_text: The end of the thread is then conducted on to the new tube, and after a few turns
have been made thereon, the finished cop may be taken off, or completely “doffed"
at convenience, and the operation may be repeated.
Variations in detail may be made without departing from the peculiar character
of the invention, which mainly consists in the employment of split longitudinal
paper or other tubes, hinged or not, in combination with a tube carrier or lifter,
and a cop rest, suitably actuated for "doffing" purposes in ring spinning machinery,

We, THOMAS THORP, of Whitefield, in the county of Lancaster, Architect; and
BENJAMIN COOPER, of 14 Brown Street, Manchester, in the county of Lancaster,
Merchant, do hereby declare the nature of our invention for "IMPROVEMENTS IN
APPARATUS CONNECTED WITH RING SPINNING" and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:-
The improvements relate to what is known as ring spinning when the same is
used for the spinning of yarn in cop form upon paper or other tubes, and consist
of certain apparatus which has for object the "doffing" of the cops from the
spindles.
To accomplish this and to effect our improvements, we employ tubes composed
of paper or other suitable substance, which are split in their length, either on one
or two sides, but by preference on one side, and capable of being opened and put on
to the spindles without sliding the same on to the ends thereof.
If a tube is cut open on one side, and only partially cut through on the other,
the two sides may be opened on a kind of hinge joint formed by the partial cut.
Or the hinge may be formed otherwise.
This hinged tube is thus capable of clasping a spindle, and fits, at its lower end,
into a tube carrier composed of a small socket placed on the spindle, and which
socket may either be constructed so as to clip the spindle by a spring, or, by pre-
ference, to have the recess for the tube formed somewhat conical, so that by simply
pressing down the tube therein, the requisite grip is obtained.
Underneath this tube carrier is fixed a suitable lifter, attached to a rod or
analagous device. This rod carrying the lifter extends to a distance above, corre-
sponding to the distance of motion given, and has affixed at that height, a cop rest,
in such form that the operator can, by actuating a lever, or other obvious mechanism,
cause the tube carrier, and cop rest to rise, and thus partly lift off the cop on the
spindle. The tube carrier and cop rest may then be allowed to resume their
original positions, and a new split tube may be adjusted in the carrier, and upon
the spindle. The end of the thread is then conducted on to the new tube, and
after a few turns have been made thereon, the finished cop may be taken off, or
completely "doffed" at convenience.
When this is done the new cop is formed upon the cop rest, and the operation
may be repeated.
But that the invention may be better understood, we will by the aid of the
accompanying drawings proceed to more fully describe means employed by us.
DESCRIPTION OF DRAWINGS,
Figs 1, 2, 3 and 4 shew elevations of apparatus arranged in accordance with our
nvention, but in different positions of action; and Figs 5 and 6 shew elevations
and plan views of a split tube of paper or other substance,

page_text: a, a, is the ring bar, which in its traversing motion forms the cop, as is well
understood. b, b, is the split tube. c, c, is the tubo carrier or lifter, and d, d, the
cop-rest supported by the rod or rods e, e, attached to the slide ff. Motion may
be given to the various parts in any convenient manner.
In Fig. 1. a cop h, h, is shewn to be about completed, and the ring bar or former t
a, a, is in consequence at about its highest elevation. The tube carrier and cop-
rest is then raised to the position of Fig. 2. having previously received the fresh
split tube b, b, which may be adjusted without passing over the end of the spindle
9, 9, and at the same time, or by a subsequent movement the cop rest can be raised
bigh enough to lift the cop sufficiently to leave it loose for rapid or automatic 1
doffing. The ring bar a, a, and cop rest d, d, can then be brought down to the
position of Fig. 3, after the thread has been transferred to the new paper or other
tube, which will have been held in position after a few turns of yarn have been
wound thereon, and the tube carrier or lifter c; c, and the cop rest d, d, may, be then
brought to the position of Fig 4, there to await the building of the new cop when
the operation may be repeated.
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
1st The employment of split paper or other tubes, in spinning cops, on what are
known as ring spinning frames, which tubes are capable of opening on a hinge or
otherwise, so as to avoid the necessity of passing the same over the ends of the
spindles, substantially as shewn and described.
2nd The employment of tube carriers or lifters, with or without springs, in
combination or otherwise with the cop rest, and other attachments, for the purpose
of manipulating split or other tubes on spindles in manner and for the purpose
substantially as shewn and described.
3rd The employment of cop rests, and suitable attachments, in combination or
otherwise with tube carriers or lifters for the purpose and in manner substantially
as shewn and described.
