Other Fibrous Threads.
I, JOHN KING Junior of Chepstow Street, Manchester in the County of Lancaster,
Cotton Spinner or Manufacturer, do hereby declare the nature of my said invention
for "IMPROVEMENTS IN APPARATUS FOR TWISTING OR DOUBLING YARN OR OTHER
FIBROUS THREADS " to be as follows:-
In the specification and drawings of Letters Patent granted to me dated 10th day
of June 1880 No. 2351, I have shown and described an apparatus for doubling
and twisting yarn by means of which two twists may be imparted for each revolu-
tion of the spindle. In that apparatus the bobbin from which the thread or yarn
is withdrawn is placed with its longitudinal axis at right angles to the longitudinal
axis of the spindle.
The object of this invention, constituting my present improvements is to fix or
erect a spindle together with its bobbin carriage, so that, whilst giving the advan-
tages of the double twist to the thread or yarn for each revolution, and embodying
the general principle of the previous invention, the longitudinal axis of the bobbin
shall be coincident with, or parallel to, the longitudinal axis of the spindle, and in
other respects improve the apparatus used for doubling yarn or thread.
In carrying out my invention I make the spindle and flyer of construction
somewhat similar to that described in the said patent No 2351 of 1880, so that the
thread or yarn can pass through the end, as therein shown.
The bobbin is carried on a separate short spindle, one end of which fits into a hole
drilled inside one end of the bobbin carriage, which carriage fits inside the spindle
flyer, the projecting ends of which spindle flyer serve as bearers for it to rest on.
The bobbin carriage at one end fits over and rests upon the projecting ending of
the spindle flyer, and at the other is fitted with a pivot or centre which rests
inside a circular hole of the same size, drilled into the other projecting end of the
spindle flyer, which freely revolves round it.
A set screw in the bobbin carriage prevents the short bobbin spindle from coming
out of its position in the end of the carriage. By unscrewing the set screw the
bobbing and its spindle can be removed when required.
The bobbin carriage is thus supported at both ends in or by the longitudinal axis
of the main flyer spindle, the bobbin spindle having its longitudinal axis coincident
or parallel thereto.

page_text: At the other end of the bobbin spindle is placed a metal disc or cross bar, pre-
ferably the former, over the end of which the thread is conveyed to its entrance
into the spindle, thus avoiding friction on the end of the bobbin.
From the other end of the bobbin carriage, that is, the end into which the bobbin
spindle passes, is fixed a rod with a curl at the end, similar to the leg of a flyer,
projecting about half the length of the bobbin, through the loop at the end of this
the thread is guided on its way from the bobbin.
In addition to this one or two bars are affixed to the disc or cross-bar, at one
side to prevent friction of the thread over the surface of the bobbin.
The bobbin spindle may be further secured in, and guided to its right position
by a projection on the under side of the disc, fitting into a groove or slot in the
bottom of the carriage.
In my former patent I arranged for the thread or yarn, after being doubled and
after passing through the rollers to be wound by friction or other means onto a
bobbin for the purpose of transport. In this patent, I purpose after passing the
yarn through the rollers, or over a single roller to convey it to an ordinary vertical
or upright doubling spindle, (either flyer or ring) by which spindle a further twist
can be given to the yarn, and so wound onto a bobbin ready for use for purposes of
manufacture.
In the driving of these spindles placed vertically it may be found of advantage to
drive both the horizontal and vertical spindles by the same band off the same
drum.

page_text: In addition to this, one or two bars L L are affixed to the end of the bobbin
carriage or to the disc or cross bar, at one side to prevent friction of the thread
over the surface of the bobbin. To prevent the bobbin carriage from turning
round with the spindle it is made heavy at M so that this part is always at the
lowest point. N is the pulley for driving the spindle, it will be seen from the
above and the drawing that the bobbin and its carriage remain stationary, the
bobbin unwinding as required, but the spindle revolves The thread leaves
the bobbin passing first into hollow end F of the spindle round one arm of
the spindle flyer in which is a groove O (Figure 2) and then enters the delivery
end of the spindle by a hole h a continuation of the groove O. escaping at P having
in its passage received two twists for each revolution of the spindle,, as in my
previously patented apparatus.
In my former patent I arranged for the thread or yarn, after being doubled and
after passing through the rollers to be wound by friction or other means onto a
bobbin for the purpose of transport. In this patent, I purpose after passing the
yarn through the rollers, or over a single roller to convey it to an ordinary
vertical or upright doubling spindle (either flyer or ring) by which spindle a
further twist can be given to the yarn and so wound onto a bobbin ready for use
for purposes of manufacture.
This is shown at Figure 3 where Q, R are the receiving rollers, the latter
preferably revolving in a trough of water as shown, the thread passes to an
ordinary spindle S, both the pulley of spindle S and pulley N of the double twist
spindle are driven from the same main driving drum T and preferably by the same
band passing in the direction indicated by the arrows in the order 1, 2, 3, 4,
1, 2, 3, 4, et cetera.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that
I make no claim for those parts not represented in figures 1 & 2 but that what
I claim is:-
The herein described improvements on my former invention substantially as
and for the purposes herein before described and illustrated in Figures 1 and 2.
