Doubler, do hereby declare the nature of this invention to be as follows:-
"
This invention relates to the mechanism for actuating the "backing off" and
taking up or winding on motions in self acting cotton twiners, the object
of my improvements being to simplify such mechanism, make it more positive
and reliable in its action, and to arrange same on one side of the headstock
and operative therefrom so that greater leverage can be obtained for giving
the requisite movement to the clutch forks which control the "backing off" and
taking up" motions.
In carrying out my said invention I employ the ordinary long lever which is
centred on a stud secured to the side frame of the headstock. To the outer end
of said long lever I attach a depending arm or lever, which hangs from a stud
secured near the end of the long lever working in a slide and carrying near its
lower end a fixed projection or finger and a hinged projection or finger, the latter
of which normally rests on the fixed finger. To the vertical shaft or spindle
carrying the clutch fork for placing the backing off, motion into and out of action,
I secure a lever extending across the headstock, the free end thereof or a connection
on same resting normally against the fixed projection and in position to engage
the underside of the hinged projection before named and being adapted, when the
long lever is depressed at the end, on the carriage having completed its outward
journey, to elevate the aforesaid hinged finger or projection and pass between
it and the fixed projection, thereby allowing the backing off motion to operate
a spring serving to draw said transverse lever between the two projections. When
the backing off motion has been disengaged by the backing off connecting rod the
transverse lever rests against the aforesaid hinged finger, thereby being disengaged
until the long lever is depressed at the other end on the carriage returning to
the spindle frame the leverage obtained by actuating the transverse lever from the
side of the headstock being greater than it is possible to obtain at present and
making the motion more reliable and positive. The long lever, through the
medium of a suitable arrangement of levers and connections, also actuates the
strap guide and transfers the strap from the fast to the loose pulley. The backing
off connecting rod is placed near the side of headstock, instead of being situated
in the centre as at present.
lever is connected to the shaft or spindle carrying the clutch fork for throwing
the taking up motion into and out of action, this lever being actuated by suitable
connections from the movements of the aforesaid mechanism to start and stop the
taking up motion at the proper times, the whole being timed and their action
determined by the pendulous motion of the long lever and endwise movement of
the longitudinal rod. The former, acted upon by the outward and inward traverse
of the carriage, and the latter being locked and released by or from the faller.
Springs are employed to assist the movement of some of the parts and return

page_text: them to their normal positions after being acted upon by the operative lever and
rod.
The apparatus herein described is applicable only to twiners having the rims
placed at the side and not at the end of the framework.

Improvements in Cotton Twiners.
I, JAMES FIELDING, of Perseverance Mill, Elland, in the County of York, Cotton
Doubler, 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 the mechanism for actuating the "backing off" and
taking up" or winding on motions in self acting cotton twiners, the object
of my invention being to simplify such mechanism make it more positive
and reliable in its action, and to arrange same on one side of the headstock
and operative therefrom so that greater leverage can be obtained for giving
the requisite movement to the clutch forks which control the "backing off" and
"taking up" motions.
In order that my invention may be better understood I have annexed the sheets
of the accompanying drawings wherein :-
Fig. 1 is side elevation shewing my improvements;
Fig. 2 is similar view shewing the position of the parts during the process of
"backing off";
Fig. 3 is end view looking in the direction of arrow a Fig. 1 and Fig. 4 is plan
view.
Fig. 5 is similar view to Figs. 1 and 2 shewing the position of the parts during
the process of "taking in."
Like letters of reference denote corresponding parts in all the figures.
Referring to the drawings 1 is the ordinary long lever centred on stud 2 secured
to the side framing 3 of the head stock. To the outer end of said long lever 1 I
attach a depending arm or lever 4 which hangs from a stud 5 secured near the
end of the long lever, or the arm 4 may be rigidly attached to lever 1, in which
case slide 6 would be dispensed with. This depending arm 4 works in a slide 6 and
it carries at its lower end a fixed projection or finger 7 and a hinged projection
or finger 8, said finger 8 resting normally upon the finger or projection 7.
To the vertical shaft or spindle 9 carrying the clutch fork 10 for actuating the
backing off clutch, (not shewn) I secure a lever 11 extending across the headstock,
the free end thereof or a connection on same resting normally against the fixed
projection 7 and in position to engage, the underside of the hinged projection 8
and being adapted when lever 1 is depressed at the end on the carriage having
completed its outward journey to elevate the hinged finger 8 and pass between it
and finger or projection 7 thereby moving the backing off clutch fork 10 as shewn
in dotted lines Fig. 4, a spring 12 assisting to draw the transverse lever 11 between
the two projections 7 and 8. When the backing off motion has been disengaged
by the backing off connecting rod 18 the transverse lever 11 rests against finger 8,
thereby being disengaged until the long lever is depressed at the other end on the
carriage returning to the spindle frame, the leverage obtained by actuating the

page_text: transverse lever 11 from the side of the headstock being greater than it is possible
to obtain at present and making the motion more reliable and positive.
The lever 11 is provided with an upright arm 11' adapted as shewn, to engage
the underside of a depending arm 19 on lever 19, thus keeping the taking-up
friction clutch disengaged during the backing-off process.
The lever 1 through projection. 13, levers 14, 15, and 16 actuates the strap
guide 17 to transfer the strap from the fast to the loose pulley. The backing off
connecting rod 18 is placed near the side of the headstock as shewn instead of
being situated in the centre as at present. A lever 19 is connected to the spindle 20
carrying the clutch fork 21 for throwing the taking up motion into and out of
action, this lever 19 being actuated by means of a projection 1' on the lever 1
which engages with an arm or depending portion 191 on said lever 19 to place the
taking up motion out of action, the weight of lever 19 or a spring serving to
operate the clutch fork 21 to place the taking up motion into action. The move-
ment of the above parts to start and stop the taking up motion at the proper
times and their action are determined by the pendulous motion of the long lever 1
and the endwise movement of the rod 18.

The holding out" catch, which however, forms no part of my invention, is
shewn at 25.
The action of the parts is as follows:-
When the parts are in the position shewn in Fig. 1, both the "backing-off"
clutch and the taking-up clutch are out of gear, and the strap is on the fast pulley,
and running the carriage out. On the carriage arriving at the end of its outward
journey the end of lever 1, is depressed, and the projection 13 thereon through
levers 14, 15, 16, and strap fork 17 acts to transfer the strap from the fast to the
loose pulley, which stops the carriage ready for backing-off. The lever 4 descends
with the downward movement of lever 1 thus allowing the lever 11 to elevate the
hinged finger 8 and by spring 12 be drawn between it and finger 7, (see Fig. 2)
wch operates the backing-off clutch fork 10 to set in motion the backing-off
mechanism.
When the backing off process is completed, the backing off connecting rod 18
is released, and a strong spring 22 serves to draw same back to the position shewn
in Fig. 5. A lug or collar 23 on rod 18 engages the upright arm 111 on lever 11
and forces said lever 11 clear of the fingers and 8 as shewn, which places the
backing off clutch mechanism out of action. At the same time the upright
arm 11 has been forced from under the projection 1911 on lever 19, thus allowing
said lever to drop and through rod 20 to operate the taking up clutch fork 21 to
place the taking up clutch into gear.
As the carriage arrives at the end of its return journey the lever 1 is raised at
its outer end, the projection 11 thereon engages the depending arm 19¹ on lever 19
and raises said lever whereby the taking up clutch fork is operated to stop the taking
up motion, a spring 24 acting at the same time to operate the strap guide 17 to
transfer the strap from the loose to the fast pulley, to run the carriage out again.
The backing off connecting rod 18 is then drawn back to the position shewn in
Fig. 1 ready for the next outward traverse of the carriage.
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 what
I claim is:
-
(1) In a self acting cotton twiner, the combination with lever 1 of a depending
arm carrying a fixed projection or finger and a hinged projection or finger,
together with a transverse lever attached to the backing off clutch fork spindle,
said transverse lever being adapted to enter and register between the hinged
projection and the fixed projection for actuating the backing off motion all
arranged, constructed and operated substantially as shewn and described and for
purposes set forth.
(2) In a self acting cotton twiner the employment of a projection 1¹ on lever 1

page_text: adapted to engage the underside of a depending arm on a lever or levers attached
to the taking up motion clutch fork, for actuating the taking up motion all
arranged and acting substantially as herein shewn and described.
(3) In a self acting cotton twiner the employment of an upright arm 11' on
lever 11 adapted to engage the underside of a depending arm 1911 on lever 19
all arranged and constructed substantially as shewn and for purposes described.
(4) The general arrangement, construction, and combination of parts as herein
described and shewn in the drawings for actuating the backing off and taking
mp motions in a self acting cotton twiner.
Dated this 1st day of February 1899.
