Complete Specification Left, 24th July, 1899-Accepted, 23rd Dec., 1899
I, JAMES PICKFORD, of 255, Shaw Road, Luzley Brook, Royton, in the County
of Lancaster, Mule Overlooker, do hereby declare the nature of this invention
to be as follows;-
This invention relates to improvements in self-acting mules for spinning and
has for its object to simplify and render more reliable in action the means which
operate the ratchet wheel click on the winding plate employed upon the tin
roller shaft.
To this end I connect the lower end of the ratchet wheel click locking lever
by means of the angular lever fulcrumed to the pivot of the faller locking lever
or direct to the boot leg suspended from the faller sector or to any other suitable
part of the mule which effects the locking of the fallers.
At the side of the said ratchet click locking lever I also employ as usually the
fork which operates the ratchet click holding out cam, but instead of liberating
the said ratchet click by a train of ievers connected to the said fork, and bringing
it into gear with its ratchet wheel by the holding out catch rod, I dispense with
such connections and form or furnish the horizontal end of the ratchet wheel
click locking lever with a projection or incline adapted to operate the said cam
fork and thereby simultaneously liberate and bring the said click into gear with
its ratchet wheel through the medium of the ratchet click locking lever.
In order to facilitate the application of my improved winding click motion to
different makes of mules I may form the said angular lever in three parts, namely,
a rod or arm one end of which is rendered horizontally adjustable in the vertical
end of the ratchet wheel click locking lever and the other end fulcrumed to a
stud carried by a bracket rendered horizontally adjustable upon the part of the
angular lever suspended from the pivot of the faller locking lever.
I may also form the ratchet wheel click holding out cam and the ratchet wheel
click locking lever in halves so as to be readily secured to or removed from their
axis when required.
According to a modification of my invention I may operate the ratchet click
locking lever through the medium of the holding out catch rod by suitably con-
necting it therewith and holding the ratchet click locking lever in position during
the inward run of the carriage by a catch employed in connection with a
stationary bracket which latter liberates the said catch when the carriage has
finished its inward run.

page_text: Improvements in Self-acting Mules for Spinning.
I, JAMES PICKFORD, late of 255, Shaw Road, Luzley Brook, Royton, now of 12,
Vigo Street, Lees Road, Oldham, in the County of Lancaster, Mule Overlooker,
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 improvements in self-acting mules for spinning and
has for its object to simplify and render more reliable in action the means which
operate the ratchet wheel click on the winding plate employed upon the tin
roller shaft.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Fig. 1 being a vertical section through
the square of the mule, Fig. 2 a plan of a portion of Fig. 1 of one form of my
invention. Fig. 3 a vertical section through the square of the mule, Fig. 4 a
plan thereof and Fig. 5 a side view of another form in which my invention may
be carried out.
In carrying out my invention and referring to Figs. 1 & 2, according to one
form of my invention, I connect the lower end of the ratchet wheel or winding
click locking lever a by means of the arm a and the angular lever connected
to the stud c of the faller locking or fish mouth lever d, to the latter or direct
to the boot leg e suspended from the faller sector f or to any other suitable part
of the mule which effects the locking of the fallers. The ratchet wheel or
winding click locking lever a when caused to move or oscillate on its axis will,
by means of the click spring mounted in a groove formed in the boss of the
lever a, cause the click to engage with the winding on ratchet wheel / as is
well understood.
Upon the boss connected to the ratchet wheel or winding click locking lever a
mounted upon the tin roller shaft and used for engaging the winding click with
the winding or ratchet wheel 7, I mount the winding click holding out cam or
cone i.
The cam or cone is operated by the fork lever h placed under the influence
of a spring h¹ secured thereto and to the square of the carriage, which spring
causes the fork lever h to slide the cam or cone i against the peg ¹ which is
secured to and forms a part of the ratchet or winding click and thereby
prevents the latter from engaging with the winding on ratchet wheel until it
has been released by the withdrawal of the cam or cone i, but instead of liberating
the said ratchet click k by a train of levers, I form or furnish the end of the
ratchet wheel or winding click locking lever a which oscillates on its axis at
times, with a projection or incline m adapted to operate the said cam or cone
fork h. The oscillation of the locking lever a simultaneously liberates, by means 4
of the said cam or cone, the click and brings the click k into gear with its
ratchet wheel l.
By the use of the cam or cone I prevent the winding click from going into
gear before the proper time and by means of the click locking device I secure
the engagement of the said click with the winding on ratchet wheel 7 thereby
preventing the winding click going into gear before the lock of the faller and
ensuring its prompt engagement when required on the lock of the fallers.
In order to facilitate the application of my improved winding click motion
to different makes of mules I may modify the form of the connecting parts, namely,
use a rod or arm a¹ one end of which is rendered adjustable in the vertical end 5

page_text: of the ratchet wheel click locking lever a and the other end fulcrumed to a stud
carried by a bracket rendered adjustable upon the part of the angular lever b
suspended from the stud c of the faller locking lever, as will be readily under-
stood without illustration.
It will be obvious that I may also form the ratchet wheel click holding out
cam and the ratchet wheel click locking lever in halves so as to be readily secured
to or removed from their axis when required to apply them to old mules.
According to another form of my invention and referring to Figs. 3, 4 & 5, I
may dispense with the aforesaid angular lever and form the boss of the ratchet
wheel click locking lever a with an arm n which I connect by means of a link o
to a lever p suitably fulcrumed and connected by a rod q to the stud c of the
faller locking or fish mouth lever d.
In order to render my improvements applicable for mules wherein the tin
roller is adapted to rotate right or left, I employ upon the ratchet wheel click
locking lever a, two projections or inclines m, as shown in Figs. 3 & 4, and I
so form the levers & that the link o may be employed at either side of the
fulcrum of the lever, see more particularly Fig. 4, to bring either of the said
projections or inclines into operation in accordance with the direction in which
the tin roller revolves.
According to another form of my invention I may simultaneously operate the
ratchet click locking lever and the cam or cone through the medium of the
holding out catch rod acting directly on the click locking lever provided with the
incline m.
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;
1st. In self-acting mules, a device for holding out the winding click, such as
the cam or cone i in combination with a winding click locking motion device,
such as a lever a, arranged and operating so that the winding click k is simul-
taneously liberated from restraint and brought into gear with its ratchet wheel
at the desired moment, all substantially as and for the purpose set forth.
2nd. The combination and arrangement of the winding click locking lever a
formed with an incline m or the like adapted to actuate the winding click holding
out cam or cone i all substantially and operating in the manner and for the
purpose set forth and illustrated in and by the accompanying drawings.
Dated this 22nd day of July 1899.
