PROVISIONAL SPE FICATION.
Improvements in Sectional Warping Machines.
We EDWIN ROTHWELL and WILLIAM ANDREW ROTHWELL both of Linnyshaw
Mill, Walkden, near Bolton, in the County of Lancaster, Manufacturers, do hereby
declare the nature of this Invention to be as follows:-
:-
The object of our invention is to dispense with much of the complicated mechanism
now generally employed and to give a positive equal traverse to the " presser " for
each revolution of the shaft on which the section blocks are mounted and to obtain a
uniform size of sections.
In carrying our invention into effect we employ the usual shaft for the section
blocks and drive the same in any convenient manner this shaft gives motion to a
ratchet pawl or pawls arranged to actuate and turn a ratchet wheel mounted on the
machine frame the centre of the wheel is bored and threaded and a screwed rod screws
into this thread pivoted to one end of the screwed rod is a rod the other end of which
is pivoted to one end of a regulating lever mounted near its centre on a pivot secured
to the frame; the opposite end of this lever has a longitudinal slot in it.
The presser is forined so as to be guided in slide ways or equivalents on the machine
frame and a rod is pivoted at one end to the presser and at the other to a stud or
block fitted in the slot of the regulating lever.
Previous to winding a trial section we slacken the stud or block so as to allow the
rod to determine the position of the stud and then tighten and fix the stud in such
position after the trial section has been formed or partly formed; the machine can
then be started and the presser will be moved automatically as the section increases in
size no further adjustment being required until the count of the yarn to be wound
into sections is changed.
A handle can be applied to one end of the screwed rod for turning the same to
move the presser forwards or backwards as required.

COMPLETE SPECIFICATION.
Improvements in Sectional Warping Machines.
We, EDWIN ROTHWELL and WILLIAM ANDREW ROTHWELL, both of Linnyshaw
Mill, Walkden near Bolton in the County of Lancaster, Manufacturers, 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:-
The object of our invention is to dispense with much of the complicated mechanism
now generally employed and to give a positive equal traverse to the "presser" for each
revolution of the shaft on which the section blocks are mounted and to obtain a
uniform size of sections.
In carrying our invention into effect we employ the usual shaft for the section
blocks and drive the same in any convenient manner this shaft gives motion to a
ratchet pawl or pawls arranged to actuate and turn a ratchet wheel mounted on the
machine frame the centre of the wheel is bored and threaded and a screwed rod screws
into this thread, pivoted to one end of the screwed rod is a rod the other end of which
is pivoted to one end of a regulating lever mounted near its centre on a pivot secured
to the frame; the opposite end of this lever has a longitudinal slot in it.
The presser is formed so as to be guided in slideways or equivalents on the machine

page_text: frame and a rod is pivoted at one end to the presser and at the other to a stud or block
fitted in the slot of the regulating lever.
Previous to winding a trial section we slacken the stud or block so as to allow the
rod to determine the position of the stud and then tighten and fix the stud in such
position after the trial section has been formed or partly formed; the machine can
then be started and the presser will be moved automatically as the section increases in
size no further adjustment being required until the count of the yarn to be wound
into sections is changed.
A handle can be applied to one end of the screwed rod for turning the same to move
the presser forwards or backwards as required.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying Sheet of Drawings reference being had to
the figures and letters marked thereon.
Fig. 1 is a front elevation Fig. 2 an end elevation and Fig. 3 a plan of part of a
sectional warping machine fitted with our improvements.
In these views-a desiguates the machine frame; 6 the usual shaft for the section
blocks; c the fixed and the movable flange on the shaft b, d is the ratchet wheel in
this case shown as a double wheel of two different diameters, e is the pawl which is
mounted on a lever f pivoted to the frame at f¹; this lever fis forked at the lower
end where it engages a grooved cam g fixed on the shaft b; the ratchet wheel dis
fixed upon a screwed boss supported in a stationary bearing and through this
screwed boss passes the screwed rod i which is connected by a rod j to the regulating
lever k. The regulating lever k is fulcrumed at k¹ and has a slot k² in it, in which is
fitted a stud or bolt the shank of which also passes through the end of a rod m, the
parts being locked together by a lever nut . The rod m is connected at the other
end by a bolt m' to the slotted presser holder n which carries the presser n' the presser
holder being supported in slideways on the under side of a carriage o which is
mounted upon a stationary bracket p and can be adjusted by means of a screw p¹; the
bracket, which is fixed to the frame of the machine, supports the parts m, n, n', o
and pl.
0,
On the shaft q is a pulley q¹ for the driving belt also a bevel wheel which gears
into and drives a similar wheel mounted on a shafts which carries a friction
roller s. The shaft s is mounted in swivel bearings and a handle is employed to
move it and bring the roller s¹ into contact with the flange or friction plate c as shown
in Fig. 3 or into contact with a friction disc b secured upon the shaft when required
to wind the section in the reverse direction.
In building a trial section the flanges c c are placed at the right distance apart with
a suitably sized presser in the holder the landnut is slackened a handle u
connected by gears to the pinion ¹ on the screwed boss is turned until the presser n'
is brought into contact with the section boss on the shaft b the yarn is now fed on to
the shaft over a guide v and the machine started the friction roller s' driving the
shaft b and other parts through the plate c. The cam g causes the lever f and pawl e
to oscillate and so drive the ratchet wheel d the rotary motion of which moves the
screwed rod i in the direction of the arrow Fig. 3 and withdraws the presser n¹ as the
section fills and until it is finished and the machine stopped. The lever nut l' is then
tightened to secure the rod m in the position it has assumed the flange c¹ and trial
section can then be removed.
The presser n is then moved back to the section boss on the shaft b by turning the
handle as before described. When the parts have been brought back to the starting
position yarn is again fed on to the section boss on the shaft 6 when a section can be
automatically built of the same pressure and size as the previous one. The pressure
can be varied for extreme counts of yarn by changing from one size of the ratchet
wheel d to the other and so altering the speed of the screwed boss / and movement of
the screw thereby varying the relative speed of the shaft and screwed boss h.
One advantage of our arrangement is that the presser is mounted in such manner
that it moves radially to and from the centre of the section shaft in place of being
swung from a centre as is usual.

page_text: Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In a sectional warping machine the combination with a pivoted slotted regulating
lever actuated by a ratchet motion or equivalent mechanism from the section shaft,
of a rod pivoted at one end to a stud fitted in the slot of the regulating lever and at
the other end connected to the presser holder which is guided in adjustable slideways
substantially as described and as illustrated by the Drawings annexed.
2. The combined arrangement of parts substantially as herein shown and described.
