FRANK RADCLIFFE, Smallware Manufacturer, Springfield Mill, Radcliffe, Lanca-
shire, ROBERT RADCLIFFE, Overlooker and Manager, Springfield Mill, Radcliffe,
Lancashire, do hereby declare the nature of this invention to be as follows:
-
Two separate motions, one for putting in the twist, and the other for winding
on the yarns or threads, as delivered from the rollers into cop form.
The twist motion, consists of a bush, with an eye on the top, working on a fast
tube, fitted to stationary rail and driven from the cylinder, by a string or tape.
The winding on or coping motion, consists of a spindle fixed to travis rail and
is lifted up and down by an heart wheel, which forms the coneish shape cop, and
is driven, by a pair of cone drums which regulate the speed of the spindles, to take
up, the yarns or threads, as twisted by the twisting motion as delivered from the
roller's; with the aid of carrier wheels, lever's and tention. plates.
The two combined forming a spinning and doubling frame of independant twist
and positive tention.

Improvements in Spinning and Doubling Frames.
We, FRANK RADCLIFFE, of Springfield Mill, Radcliffe, in the County of
Lancaster, Smallware Manufacturer, and ROBERT RADCLIFFE, of the same place,
Overlooker and Manager, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement: -
This invention comprises two separate motions one for putting in the twist and
the other for winding the yarns or threads (as delivered from the rollers) in the
form of a cop onto the spindles.
The nature of our invention and the manner in which the same is to be per-
formed or carried into practical effect will be readily understood on reference to
the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is a front elevation and Fig. 2 an end view of so much of
a spinning frame as is necessary to illustrate our invention, a being part of the
frame of the machine, 6 the roller beam, c the fixed or stationary rail which carries
the twist motion, and d the traverse or copping rail which carries the spindles e.

page_text: •
The twist motion (see enlarged detached views Fig. 3) consists of a short bush f
(formed outside like a wharve) provided at the top with an eye g carried by a
curved arm h.
This bush works or revolves on a fast tube i fitted in the stationary rail c and
is driven from the tin drum or cylinder k by an endless cord or tape passing
round the wharve of the bush f (see Fig. 2).
The spindles e which effect the winding-on are tubular and revolve on dead
spindles or pins which are fixed fast in the traverse or copping rail d, to which
latter the ordinary lifting and falling motion for forming the cone shape of the cop,
is imparted in the usual manner by the heart wheel or cam m acting upon the
lifting lever n and the spindles e wind-on or take up the yarn as it is twisted,
being driven (as hereinafter described) by endless bands passing round their
wharves e and round the tin drum or cylinder o which is carried by brackets fixed
to the traverse rail d and rises and falls therewith.
The regulation of the speed of the spindles 80 as to give a varying speed thereto
according as the yarn is being wound onto the larger or smaller diameter of the
cop is effected as follows:-
-
The winding-on drum e is driven by means of an endless band passing round
carrier pulleys q above and below and taking one turn round the pulley on the
end of the drum shaft so as to allow of the band p continually driving the drum o
and at the same time allow of the former rising and falling with the traverse or
copping rail d.
The speed is regulated by means of a pair of cone drums s and s* round which.
passes a driving strap and this strap is shifted along the cone drums so as to
regulate the speed as required by the following means:-
A rod u (see Fig. 2) connects the lifting lever n with one arm of a bell-crank
lever v, the other arm of which is slotted, and in the slot works a nut carrying a
pin or peg w to which is attached one end of a band or strap & passing over carrier
wheels or pulleys y (see also detached view Fig. 4) and having at the other end a
weight z.
This band or strap r is also connected by a lever 1 to a sliding plate or bar 2
(which I call a tension-plate") and to the centre of this bar is bolted the strap
fork 3.
<
From this it will be evident that as the lifting lever n rises and falls it causes
the bell-crank lever to rock to-and-fro and by means of the band or strap
shift the strapt to-and-fro on the cone drums ss and thus give the necessary
differential speed to the spindles.
It will be seen on referring to Fig. 2 that the pin or peg wo to which the band or
strap is connected is fixed in a nut which works in a slot in the bell-crank lever v,
and through this nut works a long screw 4 at the other end of which is a ratchet
wheel 6 (see also detached view Fig. 5) in the teeth of which is engaged a catch
or pawl 7 which takes up one or more teeth of the ratchet each time that the bell-
crank lever n rocks. At the beginning of a set of cops when winding on the bare
spindle the pin to is at its nearest position to the fulcrum as shown at Fig. 2, and
consequently the motion given to the strap fork 3 is very slight, but as the
winding-on proceeds and the cop bottom gets larger in diameter the pin wis
gradually moved outwards until the conical form of the cop bottom is completed,
and then the finger we will put the catch or pawl 7 out of gear with the ratchet
wheel 6, and the movement to and fro of the strap becomes regular until the cop
is completed so that the tension of the yarn is kept always positive throughout the
building of the cop. A regulating screw 5 is also provided by means of which
the position of the strap at starting can be adjusted when required.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
The improvements in spinning or doubling frames whereby we combine an

whole winding-on of the cop substantially as hereinbefore described and illustrated
by the drawings annexed.
