Improvements in the Governing Motion of Self-acting Mules and
Twiners for Spinning and Doubling Fibrous Substances.
I JOHN BOARDMAN of Jackson Street Mill London Road Manchester in the County
of Lancaster Spinning Master do hereby declare the nature of this invention to be as
follows:-
This invention relates to the motion known as the governing motion of mules and
twiners which moves the nut to which the winding on chain is attached along the
screw in the quadrant arın, the object of my invention being to supply a positive
motion for this purpose which shall only act at the times when it is actually
required.
mount a lever or arm upon the counter faller shaft extending in the opposite
direction to the counter faller arm and about the same length as the distance between
the centre of the said shaft and the counter faller wire. And upon a bracket fixed to
the carriage I mount a cranked lever one end of which is so formed and situated that
it can be brought against and grip the governing rope which passes round the usual
pulley upon the centre or fulcrum of the quadrant and actuates the nut above named
in the usual way.
The other end of this cranked lever carries a small pulley round which a cord or
its equivalent is passed.
One end of this cord is attached to the before described lever or arm upon the
counter faller-shaft and the other end is attached to a spring, the other end of the
latter being connected to a strap or its equivalent which is adjustably fixed to a sector
mounted upon the faller shaft.
The action of the apparatus is as follows:-
As the fuller wire is depressed for winding on it causes the sector to make part of a
revolution.
As the counter faller is also brought down the end of the lever arm is raised
and this combined action raises the end of the aforesaid cranked lever which carries
the pulley and presses the other end of the said lever hard against the governing
band or rope and the movement of the carriage pulls the said band or rope along
actuates the governing nut as before described.
.
The spring above named will yield sufficiently to prevent the motion of either the
counter faller or the faller from acting upon the cranked lever sufficiently to pull the
governing band or rope independently of the other, and it also serves as a check
on the counter faller to form a tight nose on the cop and prevents breakage of the
yarn.
When the cop has reached its fall diameter and the action of the governor is not
required the faller will no longer be depressed sufficiently to act on the governing
band or rope.
Also when the yarn is too slack and does not depress the counter faller
sufficiently the governing band, is not moved, and thus the position of the governing
nut is only altered when actually required.

Improvements in the Governing Motion of Self-acting Mules and
Twiners for Spinning and Doubling Fibrous Substances.
I JOHN BOARDMAN of Jackson Street Mill London Road Manchester in the County
of Lancaster Spinning Master 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 relates to the motion known as the governing motion of mules and
twiners which moves the nut to which the winding on chain is attached along the
screw in the quadrant arm, the object of my invention being to supply a positive
motion for this purpose which shall only act at the times when it is actually
required.
The invention will be readily understood on reference to the following description
and the accompanying sheet of drawings on which Fig. 1 is a side elevation partly in
section of so much of a mule carriage as is necessary to shew my invention applied
thereto, and Fig. 2 is a front view thereof.
a is the faller shaft, and the counter-faller shaft, c is part of the framing of the
carriage d is the governing rope or cord which passes round a pulley upon the centre
of rotation of the quadrant and actuates the nut in the usual way.
I mount a lever or arme upon_the_counter-faller-shaft b extending in-the-opposite
direction-to-the-counter-faller arm and about the same length as (or more or less
than) the distance between the centre of the said shaft and the counter faller wire. And
upon a bracket c¹ fixed to the carriage c I mount a cranked lever f,f one end of
which is so formed and situated that it can be brought-against and grip the governing
rope d-which passes round the usual pulley upon the centre or fulcrum of the quadrant,
and actuates the nut above named in the usual way.
The other end of this cranked lever carries a small pulley 9 preferably mounted,
in a rocking bracket g' round which a cord or its equivalent is passed. One end of
this cord is attached to the before described lever or arme upon the counter faller
shaft b and the other end is attached to a spring i, the other end of the latter being
connected to a strap k or its equivalent which is fixed to a sector mounted upon the
faller-shaft a.
The action of the apparatus is as follows:-
As the faller wire a¹ is depressed for winding on, it causes the sector to make
a partial revolution and as the counter faller wire is also brought down by the
yarn in the usual manner it raises the end of the lever or arm e and this com-
bined action raises the end f' of the aforesaid cranked lever which carries the pulley g
and presses the other end of the said lever hard against the governing band or rope
and the movement of the carriage pulls the said band or rope along and actuates the
governing nut as before described.
I would here remark that the cord may be attached to an ordinary adjusting
screw carried by the lever or arm e in order to lengthen or shorten it.
The spring will yield sufficiently to prevent the motion of either the counter faller
or the faller from acting upon the cranked lever f,f' sufficiently to pull the governing
band or roped independently of the other, and it also serves as a check on the counter
faller to form a tight nose on the cop and prevents breakage of the yarn.
When the cop has reached its full diameter and the action of the governor is not
required, the faller will no longer be depressed sufficiently to cause the counter faller
to act on the governing band or rope.
Also when the yarn is too slack and does not depress the counter faller sufficiently
the governing 'band is not moved, and thus the position of the governing nut is only
altered when actually required.
It will be seen that the cord h can be adjusted govern or act upon the nut at any
position of the counter faller which may be required.

page_text: It will be understood that from the foregoing description that the object or function
of the sector placed upon the faller shaft a is to lift the cord / sufficiently to cause the
raising of the lever e by the descent of the counterfaller to pull the end of the
lever hard against the governing rope.
This action being controlled by the gradual formation of the cop until it ceases
altogether when the cop attains its full diameter.
This controlling of the action of the lever e by the progress of the cop may be
obtained by other means: for example I may mount the bracket g' which carries the
pulley 9 upon a sliding picce g, moved by a screw y³, (see Figs. 3 and 4). This
screw g³, may be caused to make part of a revolution at each stretch of the carriage
by a ratchet wheel g' and a pawl g³ on a lever g which comes in contact with a
suitable fixture at the completion of overy stretch, thereby causing the bracket ¹ to
move outwards from the fulcrum of the lever ff and so reduce the action of the
counter faller upon the end f until the sliding piece g³, leaves the screw. This is set
to occur when the cop attains its full diameter and the governing nut is no longer
required to move. The spring is in this arrangement attached to the carriage c.
This modification is however more complicated than that wherein the sector (Figs. 1
and 2) is employed, as the pulley on the centro of the quadrant would have to be
provided with a catch box or clutch to prevent the possibility of the governing nut
and screw being moved during the outward run of the carriage. The wheel g*, would
have to be changed also for different counts of yarn.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. The combination with a lever which grips or otherwise acts upon the
governing rope or band of a cord or its equivalent provided with a spring and con-
nected to a lever on the counter faller shaft extending in an opposite direction to the
counter faller arm so as to rise upon the depression of the counter faller wire and so
controlled by the formation of the cop as to cease acting upon the said governing rope
or band when no longer required to move the governing nut substantially as herein-
before described.
Secondly. The combination with a lever which grips or otherwise acts upon the
governing rope or band of a cord or its equivalent, and a spring connected to a lever
on the counter-faller shaft and a sector or equivalent device upon the faller shaft, the
last named lever and the sector being both arranged to rise upon the depression of
their respective wires substantially as hereinbefore described and illustrated on the
accompanying drawings.
