I, SAMUEL HALL of 20 Varley Street, Oldham Road, Manchester in the County of
Lancaster, Manager, do hereby declare the nature of my said invention to be as
follows:-
This invention relates to improvements in machinery well known as self-actor mules
for spinning cotton and other fibrous materials and consists in providing a governing
motion to ensure even winding and the prevention of waste and snarls during the
formation of the bottom of the cop.
To the mule room floor I attach by fixings or their equivalents an adjustable slide
bar on which is mounted a sliding rack. The under side of the sliding rack is fitted
with suitable rollers to operate on the said slide bar. The back roller is slightly larger in
diameter than the front one to cant or elevate the rack from front to back to ensure its
being operated. To each end of the sliding rack is secured a band or cord which passes
round mounted pullies to a pulley on the quadrant shaft or centre. On the front of the
mule carriage is pivoted a lever with a grooved pulley or roller which is operated up
and down by a band attached to adjustable levers or quadrants mounted on the faller
rods. The pivoted lever is held in position on the face of the mule carriage by suitable
guides. When the mule carriage has completed its outward run the pivoted lever is
dropped by the action of the faller rods which places a catch mounted thereon in
position to operate the sliding rack during the inward run of the carriage, by which the
position of the winding chain on the quadrant arm is automatically regulated according
to the building or formation of the cop bottom. When the mule carriage is making its
outward run the position of the sliding rack is re-set by a fixing, mounted on the mule
carriage, operating on an adjustable conical stop secured to the aforesaid band or cord
attached to the sliding rack.
When the cop bottom is completed the pivoted lever is raised so as to place the
catch out of action with the sliding rack by the altered or raised position of the faller
rods and the adjustable levers or quadrants mounted thereon.

Improvements in Apparatus Employed in Mules for Spinning.
I, SAMUEL HALL of 20 Varley Street, Oldham Road, Manchester in the County of
Lancaster, Manager, do hereby declare the nature of my said 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 machinery well-known as self-actor mules
for spinning cotton and other fibrous materials and consists in providing a governing
motion to ensure even winding and the prevention of waste and snarls during the
formation of the bottom of the cop. To the mule room floor I attach by fixings or their
equivalents an adjustable slide bar on which is mounted a sliding rack. The underside
of the sliding rack is fitted with suitable rollers to operate on the said slide bar. The
back roller is slightly larger in diameter than the front one to cant or elevate the rack
from front to back to ensure it being operated. To each end of the sliding rack is
secured a band or cord which passes round mounted pulleys to a pulley on the quadrant
shaft or centre. On the front of the mule carriage is pivoted a lever with a grooved
pulley or roller which is operated up and down by a band attached to adjustable levers
or quadrants mounted on the faller rods. The pivoted lever is held in position on the
face of the mule carriage by suitable guides. When the mule carriage has completed
its outward run the pivoted lever is dropped by the action of the faller rods which
places a catch mounted thereon in position to operate the sliding rack during the
inward run of the carriage, by which the position of the winding chain on the quadrant
arm is automatically regulated according to the building or formation of the cop
bottom. When the inule carriage is making its outward run the position of the sliding
rack is re-set by a fixing mounted on the mule carriage operating on an adjustable
conical stop secured to the aforesaid band or cord attached to the sliding rack. When
the cop bottom is completed the pivoted lever is raised so as to place the catch out of
action with the sliding rack by the altered or raised position of the faller rods and the
adjustable levers or quadrants mounted thereon.
Fig. 1 is a side elevation of so much of a self-actor mule as is necessary to illustrate
my invention, and Fig. 2 is a part front view of same.
The fixings A are attached to the mule room floor to support the slide bar B. On
the slide bar B is mounted the sliding rack, the underside of which is fitted with the
rollers D and E. The back roller D is slightly larger in diameter than the roller E
for the purpose of elevating the rack (from front to back to ensure it being operated
by the catch F-when requisite-on the inward run of the mule carriage G. To cach
end of the sliding rack C is secured the band or cord H, which passes round the
mounted pulleys I, J, and K to the pulley Lon the quadrant shaft or centre M. On

page_text: the front of the mule carriage G is mounted the lever N pivoted on the centre 0. To
the lever N is attached the fixing P carrying the grooved pulley Qwhich is operated
up and down by the band R attached to the adjustable levers or quadrants S and T on
the copping and under faller rods respectively as shown in Fig. 3. The lever N is
held in position on the front of the mule carriage by the guide U. The lever or
quadrant S on the copping faller rod P¹ is adjustable for the purpose of regulation
according to the form of cop bottom intended to be spun. The lever or quadrant, S
is secured to the arm S¹ by the stud or bolt V as shown in Fig. 5. The lever or
quadrant T on the under faller rod V₁ is provided with the pivoted angle bracket W
and the screw X to allow of the band R being adjusted to the greatest nicety. The
angle bracket W is secured into position on the lever T by the screw Y as shown
in Fig. 4.
This apparatus operates as follows:-In caso their is too great a tension on the yarn
on the changing of the mule the copping faller S operates in the direction indicated by
the arrow in Fig. 3 and lowers the lever N placing the catch F in position for operating
the sliding rack C backwards on the inward run of the mule carriage G. The
operating of the sliding rack C causes the band or cord H to turn the pulley L on the
shaft M carrying the quadrant arm Z, by which the ordinary winding chain on the
quadrant arm is operated. Immediately the correct tension on the yarn is attained the
faller rods are operated and raised by the ordinary appliances which lifts the catch out
of gear
with the sliding rack C. The band R and pulley Q allow the faller rods P
and V¹ to operate in the usual manner without interfering with the governing motion.
The operation of the catch F on the sliding rack varies every inward run of the mule
carriage according to the varying tension on the yarn, for instance, sometimes it
operates on the first cog of the rack C, at other times on any one between it and the
last one, and sometimes not at all, the same being entirely regulated by the movements
of the faller rods and their connections. The sliding rack is brought back to its
original position, when the mule carriage G is making an outward run, by the fixing M
operating on the adjustable conical stop O¹ secured to the band or cord H attached to
the rack C. The pulley L on the shaft M is provided with the "pawl" a, as in Fig. 7,
which operates on the ratchet wheel b attached to the bush c, the latter communicating
motion to the screw d by the bevel wheels e. e. as shown in Fig. 6. The "pawl" a
operates the ratchet wheel b and its connections when the catch F engages with the
sliding rack C. The "pawl" a is held against the ratchet wheel b by the spring f.
When the sliding rack is being re-set by the outward run of the mule carriage G the
motion of the pulley L is reversed, causing the "pawl" a to slip over the cogs of the
ratchet wheel b, thus preventing the operation of the bush c, wheels e. e. screw d, and
the winding chain operated thereby.
When the cop bottom is completed the catch F, by the combined action of the lever N
and its connections and the raised or altered position of the faller rods demanded by
the increased length of the cop, is raised sufficiently to clear the sliding rack C, after
which the apparatus is stationary until a fresh set of cops are being started.
Fig. 8 is another modification of my invention wherein the slide bar B is dispensed
with. The rack C is inverted and suspended from the carriage G by the arms or rods
g and h; the outer end being attached to the lever N by the rod k, by which it is
raised or lowered by the band R ; the latter being operated up and down by the
movements of the faller rods P¹ and V₁ as previously described. The arm or rod h is
slightly longer than g to allow the rack C to drop lower at the front end than the back
to ensure of its operating on the ratchet wheel I, which elevates the rack C from front
to back in a similar manner to the rollers D and E in Fig. 1. To the ratchet wheel I'
is attached the pulley I round which the band or cord H passes to the pulley Las in
Fig. 1. The pulley L is provided with the catch box, consisting of the "pawl" a and
ratchet wheel b, as in Figs. 6 and 7, for the purpose before described in case the
motion of the pulley L is reversed by the action of the rack C on the ratchet wheel I¹
when the mule carriage G is making an outward run.
I would have it understood that I do not confine myself to the exact details or
configuration of the parts I have shown and described as the same may be varied or

page_text: modified without departing from the principle of my invention to suit the construction
of self-acting mules by various makers.
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 use, construction, and arrangement of apparatus forming my improved governing
motion for self-actor mules, to ensure even winding and the prevention of waste and
snarls during the formation of the bottom of the cop, applied and operating substantially
as described and shown on the drawings.
