page_text: LETTERS PATENT to John Elce, of Manchester, in the County of
Lancaster, Machine Maker, and Henry Birkby Arundel, of the
same Place, Manager, for the Invention of "IMPROVEMENTS IN
Scaled the 28th October 1873, and dated the 29th May 1873.
PROVISIONAL SPECIFICATION left by the said John Elce and Henry
Birkby Arundel at the Office of the Commissioners of Patents,
with their Petition, on the 29th May 1873.
We, JOHN ELCE, of Manchester, in the County of Lancaster, Machine
Maker, and HENRY BIRKBY ARUNDEL, of the same Place, Manager, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR SPINNING AND DOUBLING," to be as follows:-
Our Invention is applicable to the machines for spinning and
doubling, known as "throstles," and it consists in certain improved
combinations of machinery, whereby the yarn is distributed on the
bobbin or spool. By these improvements the yarn can be wound in

page_text: layers over the entire length of the bobbin or spool, either between
flanges or beginning at the longest layers, and gradually reducing the
length, so as to produce tapered ends, or beginning at the shortest layer,
and gradually increasing the length to produce the same result; or the
yarn can be wound on the bobbin or spool in successive conical layers,
the ascending layers being finer than the descending ones, or vice versa,
to produce what is technically known as crossing. The conical layers
may all be of the same length or parallel, or they may be shorter at each
end, and longer in the middle, or they may be short at the beginning,
and gradually increase in length until the bottom is formed, after which
they remain parallel like in a mule cop, or the layers may be shortened
at the finish.
The machinery consists, first, of a heart, which is of such a shape that
the lifting rail is caused to ascend and descend at different speeds to
produce the crossing. The heart acts on a vibrating lever, which acts
on a bowl projecting from a slide fitting on a lever which vibrates from
the axis of the heart. The slide is moved up and down by a worm fixed
on the axle of the heart. This worm gears into a wheel on an upright
shaft, to which is fixed another worm gearing into a wheel which is
adjustable on a short horizontal shaft working in bearings in the lever of
the slide. To the boss of the last-named wheel is fixed one end of a
chain, the other end of which is connected in any convenient manner to
the lifting rail. To the short horizontal shaft is fixed a crank pin,
which takes into a slot in the slide above referred to.
By changing the shape of the slot the position of the crank pin and
the angle of the levers the various modes of laying the yarn on the
bobbin or spool can be effected.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Elce and Henry Birkby Arundel in the
Great Seal Patent Office on the 28th November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
ELCE, of Manchester, in the County of Lancaster, Machine Maker, and
HENRY BIRKBY ARUNDEL, of the same Place, Manager, send greeting.

crossing. The conical layers may all be of the same length or parallel,
or they may be shorter at each end and longer in the middle, or they
may be short at the beginning, and gradually increase in length until the
bottom is formed, after which they remain parallel as in a mule cop,
or the layers may be shortened at the finish.
And in order that our Invention may be fully understood, and readily
carried into operation, we will proceed to describe the three accom-
panying Sheets of Drawings, reference being had to the figures and
letters marked thereon.
On Sheet 1 Fig. 1 is an end elevation; on Sheet 2 Fig. 2 is a front
view; and on Sheet 3 Fig. 3 is a plan of part of a ring and traveller
throstle for spinning or doubling to which our improvements are applied.
Figs. 4 and 5 represent a modification of part of our improvements;
and Figs. 6, 7, 8, 9, and 10 represent the various forms of bobbins or
spools to which our improvements are applicable.
In Figs. 1 and 2 a, a, are the tin drums for driving the spindles
and spools c; d are the lifting rails; d', the bolster rails; and a, the
footstep rails. On the axle of one of the drums a is fixed a spur pinion
for communicating motion to the shaft e, and from it to the two front
rollers ff, by the trains of wheels and pinions shewn in Fig. 1 the parts
above enumerated, and the others requisite to complete the machine,
and which are not more particularly described hereafter, are made in
any approved manner. To the shaft e, or to any other convenient shaft,
is fixed the change pinion e¹ gearing into the carrier wheel e³, which
drives the wheel g. By means of this change pinion the speed of the
whole copping motion is varied according to the counts of yarn under
operation. The wheel g is fixed to the same axle as the worm g', gearing
into the worm wheel 9 keyed on the shaft h, to which is also fixed the
heart or cam h³, which is of such a shape that the lifting rails d are
caused to ascend and descend at different speeds to produce the crossing.
The heart h¹ acts on a bowl projecting from the lever i, and this lever is
provided with a radial slot, in which the stud of the bowl is fixed,
whereby the position of the bowl can be varied to regulate the shape of
the cop or bobbin. The lever i acts on the bowl j, which is mounted in
the slide
fitting on the vibrating lever ³, the fulcrum of the lever j³

down on the lever by the inclined cam ³ fixed on the shaft 7, and this

into the ratchet wheel k³ fixed on
bearings forming part of the lever *. The ratchet wheel can be
changed for one having more or less teeth according to the shape of the
cop or bobbin required, and the throw of the lever k can be varied by
the screw k³, so as to take one or more teeth of the ratchet wheel k³ at
each throw. At the lower end of the shaft is the worm k* gearing
into the worm wheel fixed to the short horizontal shaft A working
in bearings in the lower end of the lever j³. To the shaft is
fixed or forged the crank, which takes into the curved slot at the
lower end of the slide j³, consequently as the crank & revolves it moves.
the slide up or down on the lever j³. To the boss of the worm wheel Z
is fixed one end of the chain m, the other end of which is secured to the
chain pulley m¹, and to this pulley is also fixed one end of the chain n,
the other end of which is connected to the horizontal bar n¹, which
extends as usual along each side of the frame, the said bars n¹ being
connected by chains o passing over the pulleys o¹, see Fig. 2. The
chains o are connected as usual to the pokers p supporting the lifting
rails d. In the worm wheel is a circular slot
or groove for the
adjustable stud P. At the finish of each set of cops the attendant
places a handle on the square end of the shaft k¹, and by turning it
round brings the stud against the stop j³.
The Drawing represents the parts in the positions they occupy for
building a cop similar to that shewn in Fig. 6, but by varying the shape
of the slot in the slide j¹, and the position of the crank P, and the
relative angles of the levers 7 and i, the yarn may be wound on spools
in layers, as shewn in Figs. 7 and 8.
In winding the yarn on to bobbins with flanges, as shewn in Fig. 9, it
would only be necessary to regulate the traverse of the lifting rail
according to the length of bobbin, and to throw the catch ³ out of gear
with the ratchet wheel ³.
Figs. 4 and 5 represent an arrangement of machinery for winding the

page_text: the lifting rail has to be brought back to the starting point after every
lift until a cone of yarn has been formed at the bottom of the spool, and
this is accomplished by connecting the end of the chain m to the
pulley, which is loose on the shaft 7 instead of being fixed to the boss
of the wheel 1, as before described. The pulley is fixed to the lever 1,
which is held at the commencement of a set of spools by the tension of
the chain m in contact with the stop j*. When the bottom of the spool
is formed the stud, which is adjustable in a circular slot in the wheel 7,
comes against the lever 1, and then carries it and the pulley is around
with it to form the successive conical layers.
In Fig. 4 the parts are shewn in the positions they occupy on com-
mencing a set of spools. As the crank & moves in the direction of the
arrow it gradually lowers the slide until the crank pin is moved
beyond the projection j³, at which time the bottom of the cop is com-
plete, and the partial disc then fits in the circular opening in the slot
in the slide, where it remains until the spool is filled. The stud ♬ in
the worm wheel 7 comes against the end of the screw j³, which acts as a
stop, when the parts are brought back to their original positions before

Arundel, have hereto set our hands and seals, this Twenty-
seventh day of November One thousand eight hundred and
seventy-three.
