Improvements in or connected with Frames for Spinning, Doubling,
and Winding Fibrous Materials.
We, SAMUEL HERBERT BROOKS, Machinist, THOMAS GOODBEHERE, Manager,
and WILLIAM HALL COOK, Assistant Manager, all of the Union Iron Works,
West Gorton, in the County of Lancaster, do hereby declare the nature of this
invention to be as follows :-
This invention refers primarily to ring spinning and doubling frames (but may
also be applied to flyer frames such as are used for spinning and twisting certain
classes of fibres) and also to winding frames.
In ring frames where a shortening motion has hitherto been used-i.e. a motion
whereby a constantly varying length of lift or traverse of the ring rail is produced
so that at first the traverse given to the rail is equal to the total length of the cop
or bobbin required and at each successive lift is gradually reduced in length or
shortened at the termination of the winding of each layer it has been difficult to
obtain a well-shaped taper on the bobbin or cop in consequence of the varying
radius of the chain, and there has also been required an excessive amount of feed
to the nut attached to the chain to obtain the necessary shortening of the lift. This
invention is designed to provide improved parts to the building mechanism so as to
remove these difficulties.
The main parts of the frame will be constructed in the usual way and the
builder motion will be operated by a heart shaped cam of the ordinary construction
engaging with a pivoted lever which is connected by means of a chain with the
builder shaft.
Instead however of the ordinary lever by which the building or traverse shaft is
operated we employ a double lever or two levers operating together pivoted upon
separate studs. The first of these levers is actuated by the builder cam which
engages with a friction bowl or runner at one end thereof. This lever carries a
screw and sliding nut or bracket which slides along a slot or groove in the lever as
the screw is turned. The sliding bracket or nut carries a friction bowl which
engages with the second lever preferably passing into a slot or groove therein but
it may be fixed outside the second lever so as to engage with its upper side. The
second lever is pivoted to a fixed stud-preferably near the free end of the first
lever and is actuated or raised and lowered by the sliding bracket or nut which
engages with it. The screw which moves the sliding nut is rotated in the usual
way by a ratchet and pawl by which it is moved forward one or more teeth at
each lift.
As the movement of the sliding bracket or nut is gradually from the free end
towards the pivoted end of the first lever and gradually towards the free end of the
second lever the lift of the bracket or nut and consequently the lift of the second
lever is gradually being shortened or reduced in length.
The lift or traverse chain which is connected to the builder shaft at one end is at
the other attached to this second lever so that as the movement or lift of the lever
is gradually shortened the lift or traverse of the ring or bobbin rail will also
be shortened after each lift at the termination of the winding of each layer
of yarn.
The levers may either be right or left hand and the screw will be right or left
hand as required according to the side on which the feed takes place.
The invention may be applied either to rails lifted or lowered by chains attached
to the builder shaft or lifted and lowered by levers connected thereto.
In operation the levers are first set when the bobbins are empty to allow the

page_text: lift or traverse to be the full length of the cop or bobbin; at each successive lift
the sliding nut or bracket is brought nearer to the pivoted end of the first lever by
the gradual rotation of its screw and the lift or distance traversed by it is
constantly decreased and thus the lift or distance traversed by the second lever
which connects with the builder shaft is at the same time gradually shortened.
If desired the position of the several parts and the feed of the screw may
be reversed at starting so that the lift or traverse would be constantly lengthened.

COMPLETE SPECIFICATION.
Improvements in or connected with Frames for Spinning, Doubling,
and Winding Fibrous Materials.
We, SAMUEL HERBERT BROOKS, Machinist, THOMAS GOODBERERE, Manager,
and WILLIAM HALL COOK, Assistant Manager, all of the Union Iron Works,
West Gorton, in the County of Lancaster, 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 refers primarily to ring spinning, doubling and winding frames
(but may also be applied to flyer frames such as are used for spinning and twisting
certain classes of fibres).
In ring frames where a shortening motion has hitherto been used-i.e. a motion
whereby a constantly varying length of lift or traverse of the ring rail is produced
so that at first the traverse given to the rail is equal to the total length of the cop
or bobbin required and at each successive lift is gradually reduced in length or
shortened at the termination of the winding of each layer-it has been difficult to
obtain a well shaped taper on the bobbin or cop in consequence of the varying
radius of the chain, and there has also been required an excessive amount of
feed to the nut attached to the chain to obtain the necessary shortening of
the lift.
This invention is designed to provide improved parts or combination of parts
with the building mechanism in order to obtain more even winding and better
shaped bobbins and it consists essentially in the combination of two pivoted levers
one of which receives motion direct from the heart shaped builder cam and the
other which is connected to and actuates the lifting chain receives motion from the
first lever.
It will be fully described with reference to the accompanying drawings in which
sufficient of the machine is shown to illustrate the invention.

Fig. 2. end elevation of same.
Fig. 3. transverse section on line x-x.
Fig. 4. transverse section on line y-y.
Fig. 5. modified form of second lever F.
The main parts of the frame will be constructed in the usual way and the
builder motion will be operated by a heart shaped cam A of the ordinary
construction.
Instead however of the ordinary single pivoted lever which engages with the
builder cam A. and actuates the builder shaft to which it is connected by means of
the chains C and D we employ a double lever or two levers E and F operating
together pivoted at their opposite ends upon separate studs e and f. The lever E
is pivoted upon the stud e and is actuated direct by the builder cam A which
engages with the friction bowl or runner e' at the other end. This lever carries or
is fitted longitudinally with a screw G and sliding nut or bracket H which
preferably slides along a slot or groove hi therein as the screw is turned and to the

page_text: lower end of the nut or bracket H is fixed a stud I carrying a runner or friction
bowl. The second lever F is placed alongside of the lever E and is pivoted upon
the fixed stud f at the end nearest to the free end of the lever E. The stud I
which is carried by the sliding nut or bracket H engages with the lever E preferably
in a slot therein as shown in Fig. 1. though if desired it may only bear against
its upper side as shown in the modified form in Fig. 5. As the lever E is raised
and lowered by the builder cam A the lever F is moved up and down by the sliding
bracket H and stud I.
The screw G which moves the sliding nut or bracket H is rotated in the usual
way by a ratchet wheel K on the end and a pawl k by which the ratchet wheel is
moved forward one or more teeth at each lift.
As the movement of the sliding bracket or nut H is gradually from the free end
towards the pivoted end of the lever E and gradually towards the free end of the
second lever F the lift of the bracket or nut and consequently the lift of the second
lever is gradually being shortened or reduced in length after each lift.
The lift or traverse chain CD which is connected to the builder shaft at one end,
is at the other attached to the free end of the lever F so that as the movement or
lift of the lever is gradually reduced in length the lift or traverse of the ring or
bobbin rail will also be shortened after each lift at the termination of the winding
of each layer of yarn.
The levers may either be right or left hand and the screw will be right or left
hand as required according to the side on which the feed takes place.
The invention may be applied either to rails lifted or lowered by chains attached
to the builder shaft or lifted and lowered by levers connected thereto.
In operation the levers E and F are first set when the bobbins are empty to allow
the lift or traverse to be the full length of the cop or bobbin ; at each successive
lift the sliding nut or bracket H is brought nearer to the pivoted end of the lever E
by the gradual rotation of the screw G and the lift or distance traversed by it is
constantly decreased and thus the lift or distance traversed by the lever F which
connects with the builder shaft is at the same time gradually shortened.
If desired the position of the several parts and the feed of the screw may be
reversed at starting so that the lift or traverse would be constantly lengthened.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a frame for spinning doubling and winding fibrous material a building
motion provided with two levers one actuated direct by the builder cam and the
second by a sliding bracket or stud carried by the first whereby the traverse or
lift thereof is gradually reduced or shortened (or gradually increased and lengthened)
substantially as described.
2. In a frame for spinning doubling and winding fibrous materials the combination
of the builder cam A, a pivoted lever actuated direct thereby carrying a sliding
bracket H and a rotating screw G, a second pivoted lever F actuated thereby and
connected to the traverse chain C, and a ratchet and pawl for actuating the screw
all constructed and arranged substantially as described and shown.
