Improvements applicable to Self-acting Mules for Spinning Cotton
or other Fibres.
I, JONATHAN HARGREAVES, of 27, Lodge Road, Hindsford, near Manchester,
in the County of Lancaster, Mill Manager, do hereby declare the nature of this
invention to be as follows:
This invention is applicable principally to self acting mules made upon what
is known as the Dobson & Barlow principle, but it can also with slight modifica-
tions be applied to other forms of mule.
The object of the invention is to provide means for putting the drawing-up
cone of the mule more quickly into gear when the faller "locks."
According to the present arrangement when the lever called the "gun-lever"
moves inwards (say) about two inches and a half, a bowl fixed thereon comes
against an incline on one arm of a lever, the other arm of which is provided with
a stop which in its turn raises the horizontal arm of a bell-crank lever, the vertical
arm of which latches onto a square stud fixed at the lightest end of the "long-
lever" of the mule, when the action of the "gun-lever releases the light end
of the "long-lever" and allows the heavier end thereof to fall.
"
Near this end is fixed a pin which acts against a swinging lever, at the top end
of which is the stud which acts upon the "drawing-up-cone so that as the said pin
falls it allows the "drawing-up" lever to go into gear.
The object of my invention is to dispense with the greater portion of this
movement and to substitute a simpler arrangement therefor which allows the
drawing-up" lever to act more quickly.
"
On the "backing off" rod I fix an inclined bracket on the side of which is a
projection; a swing lever is pivotted to the "backing-off" rod and is connected
by a link to the "faller leg," and a bowl or other projection on the top of this
swing lever presses against the projection on the inclined bracket and pushes
it forward at the termination of each outward run of the carriage. This forward
movement of the bracket causes a bowl (fixed in a lever which is fastened on
the "drawing-up" stop rod) to rise up the incline and thus hold the "drawing-up"
cone out of gear until the faller locks and releases it again. The "backing-off"
spring is charged or compressed by the action of the bowl or projection on
the swing lever above mentioned.

When my invention is to be applied to mules in which the "drawing-up"
cone is placed in a vertical position, I put the above mentioned bowl at the end
of the "backing-off" rod, and I place the incline on the lever which lifts the
"drawing-up cone dish, and so arrange the same that when the faller locks,
the backing-off" rod moves quickly inwards and carries the bowl under the
incline on the lever, and thus allows it to fall and put the cone in gear.
"
Or, it may be arranged to connect the "backing-off" rod with the inclined
lever which at present takes the "drawing-up" cone out of gear. The raising

page_text: or lowering being obtained by the inclined lever, the top of which I connect to
the "backing-off" rod instead of putting the incline on the cone dish lever.

Improvements applicable to Self-acting Mules for Spinning Cotton
or other Fibres.
I, JONATHAN HARGREAVES, of 27, Lodge Road, Hindsford, near Manchester,
in the County of Lancaster, Mill Manager, 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 is applicable principally to self acting mules made upon what
is known as the Dobson & Barlow principle, but it can also with slight modifica-
tions be applied to other forms of mule.
The object of the invention is to provide mcans for putting the drawing-up
cone of the mule more quickly into gear when the faller "locks."
According to the present arrangement when the lever called the "gun-lever"
moves inwards (say) about two inches and a half, a bowl fixed thereon comes
against an incline on one arm of a lever, the other arm of which is provided with
a stop which in its turn raises the horizontal arm of a bell-crank lever, the vertical
arm of which catches onto a square stud fixed at the lightest end of the "long-
lever" of the mule, when the action of the "gun-lever" releases the light end
of the "long-lever" and allows the heavier end thereof to fall.
"
Near this end is fixed a pin or stud which acts against a swinging lever, at the
top end of which is the stud which acts upon the drawing-up-cone" so that as
the said pin or stud falls it allows the "drawing-up" lever to go into gear.
The object of my invention is to dispense with the greater portion of this
movement and to substitute a simpler arrangement therefor which allows the
"drawing-up" lever to act more quickly; and the invention will be readily
understood from the following description on reference to the accompanying
drawing which shews in side elevation and section so much of a mule in which
the drawing up cone is placed on a vertical shaft as is necessary to illustrate
the said invention.
On the drawing, a is the drawing up cone dish raised as usual by a lever b on
a fulcrum b, c is the backing off rod, and d the carriage square. I fix a bowl e
on the backing off rod c and a projection f on the same rod.
A swing lever g is pivotted to the carriage square d and is connected by a link h
to the faller leg i; and a bowl g or other projection at the top of this swing
lever g presses against the projection f on the backing off rod c as the carriage dis
completing its outward run and pushes it forward, and when the faller locks the
swing lever g is forced backwards and releases the backing off rod c which moves
quickly inwards, and carries the bowl e with it under the incline 6¹ and allows
the lever b to fall and put the cone dish a in gear.
Or, it may be arranged to connect the "backing-off" rod with the inclined
lever which at present takes the "drawing-up" cone out of gear. The raising
or lowering being obtained by the inclined lever, the top of which I connect to
the “backing-off" rod instead of putting the incline on the cone dish lever,

page_text: Or I may fix an incline on the backing off rod actuating a bowl upon a lever
which puts the drawing up cone out of gear.
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:-
The combination of the swing lever g bowl or stud g³ and projection f on the
backing off rod of a bowl such as e and incline such as b₁ in connection with the
lever b substantially as and for the purpose herein before described.
