We, CHARLES WILLIAM LANCASTER, of Willows Iron Works, Accrington, in the
County of Lancaster, Engineer, and ERNEST THORMANN of Poutay, Alsace, Germany
Spinner, do hereby declare the nature of this invention to be as follows:-
This Invention relates to improvements in spinning and doubling machines and
more particularly to the spinning and doubling frames known as ring throstles or
ring frames, whereby we facilitate the operation of doffing.
In the Ring frames now in use, and particularly in those having "Sawyer" or
"Booth-Sawyer" spindles, a great loss of time accrues in doffing, inasmuch that the
frames are stopped during from to 30 Minutes for this operation, according to
the number of spindles in the frame or the number of hands employed in the
operation.
We obviato this defect and reduce the time required for doffing to a minimum, by
so placing a bobbin, or its equivalent, upon the spindles, that this bobbin while capable
of being easily and expeditiously removed when desired, always rotates with the
spindle and also remains thereupon during the process of doffing, as we spin the
yarn upon a cop, paper or other tube, which we draw over the combined spindle
and bobbin, but always so that its bottom does not reach the lower end of the bobbin.
Previous to stopping the machine for the purpose of doffing we let the ring rail
down and wind a few coils of yarn around the bottom of our bobbin, thus forming
the nucleus of another cop; we then stop the machine and draw off or doff the cop,
paper, or other tubes, upon which the yarn has been spun, place another tube upon
our combined bobbin and spindle and again start the frame, the spinning then
continuing from the aforesaid nucleus, instead of as hitherto several coils of yarn
being wound on the fresh tube or bobbin by hand before it is placed upon the
spindle.
It will be evident therefore that the frame need only be stopped long enough for
the
the removal of the filled cops or tubes and the substitution of other empty tubes;
time_now-occupied by hand-winding-or-otherwise preparing-for-the-spinning of
another cop or tube being wholly economised.

Wo CHARLES WILLIAM LANCASTER of Willow Iron Works Accrington in tho
County of Lancaster, Engineer, and ERNEST THORMANN of Poutay Alsace Germany,
Spinner do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:-
This Invention relates to improvements in spinning and doubling machines and
particularly to the spinning and doubling frames known as ring throstles or ring
frames, whereby we facilitate the operation of doffing.
2.2
In the ring frames now in use, and particularly those having "Sawyer" or Booth-
Sawyer spindles a great loss of time accrues in doffing, inasmuch that the frames
are stopped during from 5 to 30 minutes for this operation, according to the number
of spindles in the frame or the number of hands employed in the operation.
We obviate this defect and reduce the time required for doffing to a minimum, by
so placing a bobbin, or its equivalent, upon the spindle that the bobbin while capable
of being easily and expeditiously reinoved when desired, always rotates with the spindle
and also remains thereupon during the process of doffing; as we spin the yarn upon
a cop, paper or other tube which we draw over the combined spindle and bobbin, but
always so that its bottom does not reach the lower end of the bobbin.
On the accompanying sheet of Drawing,
Figure 1 represents in sectional elevation a complete spindle embodying our
invention.
Figure 2 our cop, paper or other tube as it appears when removed from the
machine-filled with yarn.
Figure 3 the wood bobbin detached.

Figure our paper tube for application over the bobbin shown Fig. 3.
Similar letters of reference indicate similar parts in each of the figures respectively.
A being the spindle. B spindle collar. CD rails in which the spindle collars and
footsteps are fixed. E spindle warve to be driven by a spindle band in the usual
manner. If wooden bobbin on spindle A and projecting at below the paper tube G
perched on or drawn over said bobbin. H yarn spun on to paper tube G.
The method of doffing by our arrangement is as follows:-
When the tube G is filled with Yarn, and while the spinning frame is still in motion.
the ring is let down in the usual way and a few coils of yarn are spun and wound
around the hobbin F below the tube G as at f Fig. 1 forming the nucleus of another
cop the machine is then stopped, and the cop, paper or other tubes G upon which
the yarn H has been spun, are doffed, that is to say drawn off the bobbin F which
remains on the spindle; another empty tube G (see Fig. 5) is placed upon the
combined bobbin and spindle and the frame again started, the spinning then continuing
from the nucleus at f.

page_text: Thus the connection between the delivery roller and the bobbin F remains
unbroken and the moment the empty tube G is placed on the bobbin F of the
spindle A-the machine is ready to resume the spinning operation and a great amount
of time is economised.
Heretofore the bobbin F was removed with the yarn from the spindles and several
coils of yarn had to be wound by hand around an empty bobbin before it was placed
on the spindle ready for another start, whereas with our arrangement the frame need
only be stopped long enough for the removal of the filled cop or tubes and the
substitution of other empty tubes; the time now occupied by hand winding or
otherwise preparing for the spinning of another cop or tube being therefore wholly
economised.
The tube G being very thin and light it can be more readily transported from place
to place than a heavy wood bobbin and the yarn can also be steamed, this tube made be
made of paper or any suitable material and we do not limit ourselves to the use of
any particular material for any part of our arrangement.
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 we
claim is :-
In spinning and doubling machines, a bobbin (F) fixed upon and rotating with the
spindle (A), in combination with an eveloping tube (G) upon which the yarn is spun,
this tube being so fitted on the bobbin that this latter projects below it (f) to receive
yarn for facilitating the renewal of the work, called "doffing" of the filled tub.; and
the substitution of a fresh one substantially as described.
