Improvements in Mechanism for Driving the Spindles of Self-
acting Mules for Spinning Cotton, Wool, and other Fibrous
Materials.
I JOHN DODD of Hartford Works, Oldham in the county of Lancaster Machinist
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 :-
"
In self-acting mules whether single speed or double speed which spin on what is
known as the woollen system the "delivery rollers are stopped considerably before
the carriage has completed its "outward run." As soon as the rollers are stopped the
sliver or thread being spun is drawn or elongated, by the further movement of the
carriage and spindles as is well understood.
Ordinarily in this kind of self-acting mule the spindles during the outward run of
the carriage are driven at an uniform or regular speed, but in some cases it is found
desirable to run the spindles slower whilst the rollers are delivering the sliver or
during some portion of the time the rollers are delivering the sliver so that it may
receive a less amount of "twist" in order that the subsequent operation of " drawing'
the sliver may be more easily performed.
"
"
39 this
In "self-acting mules" constructed on what is known as the "Platt system
reduction of the speed of the spindles has been effected by the use of a device known
as the "spindle stopping motion" which consists of a friction clutch, one part of
which is provided with suitable grooves for receiving motion from the well known
"rim band." The said part of the friction clutch revolves loosely on the tin roller
shaft; the other part of the said friction clutch is connected to the tin roller by means
of a disc" which permits of its being slidden into and out of gear with the revolving
part of the friction clutch. When the two parts of the friction clutch are geared
together with sufficient force, motion will be imparted to the "tin roller" and spindles
from the "rim band" as though the "pulley part" of the friction clutch were fast
on the "tin roller shaft." If however the part of the friction clutch sliding on the
"tin roller shaft" is only allowed to be slightly pressed against the driven part of
the friction clutch, it, as will be readily understood, will not be driven at the full
velocity, but owing to the slipping which will take place it will be driven at a slower
speed than if the two parts of the friction clutch were properly in gear. Suitable
arrangements are provided by which the amount of pressure exerted on the friction
clutch can be regulated, as also the interval during which the "spindle stopping
motion " may remain in action. As soon as the friction clutch is allowed to pass
fully into gear the spindles will be driven at their normal velocity.

"
In spinning some kinds of yarn the above described "spindle stopping motion" is
not found sufficiently reliable and uniform in its action when driving the spindles,
owing to its not being "positive in its action. The object of my- Invention is to
remedy this defect by imparting a positive motion to the spindles. For this
purpose I keep the two parts of the friction clutch above mentioned out of contact
with each other and "drive" the "tin roller" positively by means of an additional
"rim band." This additional "rim band" receives notion from a shaft mounted on
the "headstock" or in suitable bearings fixed to the ceiling of the room or supported

page_text: in any other convenient manner. The said shaft I provide with suitable pulleys one
of which at times by means of "clicks" imparts motion to the shaft on which it is
mounted. The said pulleys are " driven " by means of a belt from a pulley on the
countershaft which imparts motion to the ordinary "rim shaft" of the "mule head-
stock," or the said additional "rim band " may receive its motion direct from the
countershaft and drive the "tin roller" by means of a suitable friction clutch. I
provide suitable arrangements by means of which as soon as the two parts of the
friction clutch which previously constituted the "spindle stopping motion," are
allowed to gear together, the additional rim band' will cease to "drive" the
spindles which will then be driven by means of the ordinary "rim band "at their normal
velocity.
The velocity of the spindles can be regulated by changing the size of the "rim
which "drives" the additional "rim band."

Figs. 12 and 13. are enlarged views of parts of Figs. 10 and 11.
The same letters of reference are applied to the same parts in all the drawings.
The rim band" arrangement for driving the "tin roller" shaft c is shown as
a single band in order to make the drawings more readily understood..
This band a
is usually a double band. The additional "rim band "g is also shown single although
this band may be a double band.
"
The internal part of the friction clutch bis provided with one groove b¹ to receive
the rim band a which imparts rotary motion to it. This part is free to turn on the
"tin roller" shaft e which is coupled to the "tin roller" in the usual manner.
The
part is prevented from moving end wise on the "tin roller" shaft c by the pedestal c¹
on one side, and the disc c² on the other side. The disc 2 is a well known device and
is keyed on the "tin roller " shaft c. 63 is the "he" part of the friction clutch which is
mounted upon the "tin roller" shaft c and is free to be slidden thereon. The part 6³
provided with two projections which pass into corresponding notches or openings
formed in the "disc" c² and which whilst permitting the part 63 to be slidden endwise
on the shaft c prevent it from turning on the shaft c.
с
The part when rotated carries
round with it the "disc" and the tin roller shaft c. A groove is formed in
the boss of the part 63. Mounted on a stud d secured to a bracket bolted to the
square z of the carriage is a forked lever d¹. This lever d¹ is provided with
swivel studs which take into the groove of the part 13. One arm of the
lever d¹ projects upwards beyond the boss of the part 3 and at its upper end is
provided with a bracket which by means of a stud f carries the tumbler lever fl.
By means of the lever d¹ the part of the friction clutch 3 can be engaged with
and disengaged from the other part of the friction clutch 6 by means which will
hereinafter be described. Mounted on the "tin roller" shaft c is a spiral spring c³
tending to expand lengthwise. One end of the spring 3 abuts against the pulley c
secured to the "tin roller" shaft c and the other end presses against the boss of
the part of the friction clutch 63 which it tends to force into contact with the

arm to which one end of a spring is secured, the other end of the spring d

the friction clutch into gear.
Secured to the framing of the "headstock" y is the adjustable rail e which is
formed in two parts so as to be capable of being lengthened and shortened. The
principal part of the rail e presents a straight face, but a portion of each of the
ends is cut away so as to be inclined to the face of the straight part as shown
at e¹ and e².
23
This rail e is supported by brackets e³ secured to the framing y and adjusted by
means of adjusting screws e so that its face may be parallel to the line of the
"slips" on which the "mule carriage' moves when at work. The tumbler lever f
before referred to is mounted on the stud f secured to the bracket at the upper
end of the lever d¹. The tumbler lever is prevented from moving on the stud f
in one direction by the part d' of the bracket d. f³ is a coiled ribbon" spring,
one end of which is secured to the end of the stud which carries the tumbler
lever. The other end of the spring f³ is secured to the tumbler lever f¹ by
screw. The pressure of this spring tends to keep the tumbler lever fl against
the part d' and whilst permitting the tumbler lever f¹ to be pushed away from the
part returns it again as soon as it is permitted to do so. The free end of
the tumbler lever f is provided with an anti-friction bowl and when the parts
are properly adjusted the anti-friction bowl f5 will come in contact with the rail e
shown in Figs. 3. 4. 5. 8 and 9.
a
So far the parts described are those used in the "Platt system" of self-acting
mules. It is unnecessary to describe the arrangement and operation of the ordinary
"rim band " a in this system as it is well understood; the arrangement however is
shown in Figs. 1 and 2, sheet 1. and Figs. 10 and 11. sheet 2.
e is a pulley which is provided with a groove for the purpose of receiving the
additional rim band" g. Figs. 1 and 2 and 10 and 11 show a shaft h. This shaft
is mounted in suitable hangers or bearings and in Figs. 1 and 2 secured to the
ceiling of the room. The hanger Figs. 1 and 2, sheet 1, is provided with a pro-
jecting part 2 to which is secured the tightening bracket which is provided with a
number of slots into which the stud for carrying the pulley g² is secured so as to form
a means for regulating the tension of the band g. In place of this arrangement a
tightening apparatus such as may be substituted, see Figs. 10 and 11, sheet 2. The
shaft is formed at one end with an enlarged part or block which is provided with
the usual three pegs. The end of the shaft which projects beyond the block part h¹
is formed with a screw to receive a nut ², that is to say, it is made like the end of an
ordinary Platt" rimshaft so that an ordinary double grooved rim pulley with three
holes in the plate part may be secured to it by means of the nut h² in the usual way.
By this means the rim pulley g¹ can be readily changed for the purpose of varying
the speed.
manner.
"
"
Upon the shaft near to the other end is mounted a pair of pulleys he h³. The
pulley is loose on the shaft and constitutes a loose pulley. The pulley h³ is also
loose on the shaft h, but secured to the pulley is the stud ; which carries a click
catch; capable of engaging into a "click "wheel 2 keyed on the shaft h. The boss
of the "click" wheel is provided with a groove j³ to receive the well known "click"
spring one end of which is connected to the "click" catch j¹ in the ordinary
The pulleys alternately receive motion by means of a belt k from a
drum of suitable size on the counter shaft 2. Secured to one end of the short
rocking shaft which is carried by the hanger i. or by suitable brackets fixed to
the ceiling, is a bell crank lever" having one end formed into a slot 12 to
receive the stud 13 which is secured to the slide bar m. The other arm of this lever
is provided with a counter balance weight 1. To the slide bar m, the strap-fork m
for moving the strap k from one pulley to the other is bolted. The slide bar mis
provided with stops which limit its sliding motion to the width of the two pulleys h³ ³.
At the other end of the rocking shaft is secured a lever which is connected by means
"

page_text: of a swivel joint 16 to a vertical rod 1. The counter balance weight causes the
rod to have a tendency to lift in the direction indicated by the arrow 18. The
vertical rod 17 is connected at its lower end with the strap-lever n used for traversing
the "rimshaft driving belt" n'. Secured to the lower end of the vertical rod / is a
bracket one end of which is formed into a slot 10 to receive the stud n² which is
secured to the strap lever n.
The additional endless "rim band" 9 after passing round the double grooved
"rim" g on the shaft passes round the carrier pulley g² secured to the projecting
part of the hanger . It then again passes round the "rim" g' and then round
the carrier pulley 93 at the back of the "headstock." It then passes round a carrier
pulley g situate at the other end of the "headstock." It then passes round the
pulley secured to the "tin roller" shaft e then passes round the carrier pulley g³
secured to the "square" 2 of the carriage. From thence the band passes round a
carrier pulley situate at the back of the headstock from which it passes up to the
rim pulley g. The pulley g at the front end of the headstock is mounted in a
"tightening
frame g by means of which the tension of the rim band g is also
regulated..
"
The action of the parts above described is as follows
When the operation of the "backing off" has been performed and the mule
carriage is making its inward run the part 63 of the friction clutch will be geared
with the part b.
When the carriage during its inward run arrives at the position
which brings the anti-friction bowl in contact with the inclined end e of the
rail e the tumbler lever f¹ will turn on its axis by overcoming the elasticity of the
spring which will permit the anti-friction bowlf to slide along the rail e until
it passes over and beyond the inclined end e² without having caused the lever d' to
move in the direction indicated by the arrow e thus permitting the friction clutch
to remain in gear. When the carriage arrives at the end of its inward run the
automatic action of the self acting mule wbich is well understood will by means of
the "cam-shaft changes" cause the driving belt n' to be traversed froin the loose
pulley n on to the slow speed pulley n³ when motion will be communicated to the rim
shaft n and the "rim"n". At the same time the vertical rod will be pulled down
and the belt be moved on to the pulley 5 when the said pulley will be driven.
The rotation of the rim shaft n° will communicate motion by means of a train of
gearing to the rollers and drawing out motion of the carriage. The tin roller shaft c
will receive motion from the "rim" n' through the rim band a and the spindles will
be driven at the slow or normal speed. The rotation of the tin roller shaft e will at
the same time by means of the pulley e and additional rim band communicate
motion to the shaft h. The "click" catch j' secured to the pulley which is now
driven by the belt would at once engage with the teeth of the ratchet wheel if it
were not for the fact that the shaft and ratchet wheel are already revolving at
a greater velocity than the pulley which carries the "click" catch j¹.
When the carriage has moved a short distance on its outward run, this distance
being capable of being regulated at pleasure, the anti-friction bowl fo will come in
contact with the inclined end e² of the rail e. The further movement of the carriage
will cause the anti-friction bowl f' to "ascend" the inclined end e² of the rail e and
force the tumbler lever f' to which it is secured, in the direction indicated by the
arrow and in so doing will by means of the lever d', disengage the two parts b.
and 3 of the friction clutch, when the tin roller shaft c will cease to receive motion
from the rim band a and the shaft e being no longer driven loses its velocity and
with it the speed of the pulley c* and the shaft is reduced until the velocity of the
shaft is less than the velocity of the pulley 5 when the "click" catch j engaging
with the click wheel 2 will drive the shaft h and by means of the rim g¹, band
9,
and pulley, will give motion to the "tin roller shaft c and so drive the "tin
roller and spindles at a reduced or slowest velocity.
The further outward movement of the carriage will cause the anti-friction bowl fo
to arrive on the incline e' at the end of the rail e which permitting the lever d¹ to
move in the direction contrary to that indicated by the arrow e will by means of the

page_text: $.
23
springs c³ and d cause the parts 63 and 6 of the friction clutch to be re-engaged which
at once causes the tin roller"
c to be again driven by the rim and a at the "slow
or normal speed. The increased velocity of the "tin roller shaft" will by means of
the pulley and band g cause the shaft and click whej to over-run the click
catch when the belt will cease to drive the spindles.
C
The further outward run of the carriage, the engagement of the double speed
motion, the necessary changes to cause the "backing off" to take place and the
carriage to make its inward run, will be performed as usual.
n
When the strap-lever n moves the belt n' from the "slow speed" pulley n³ to the
"quick" or "double speed" pulley n the vertical rod 1 connected to the strap-lever
will by the action of the weight 1 cause the belt k to be traversed from the pulley
to the pulley so as to leave the pulley free when the shaft is reversed during
the "backing off." The belt is kept on the pulley * during the inward run of the
carriage so as not to interfere with the "winding."
"
The time during which the "slowest speed" is allowed to operate is regulated
by the length of the adjustable rail e which is formed in two parts so as to give
the minimum and maximum of time that the "third" or "slowest speed" may
require to be in action. It will be understood that the sizes and speed of the
various rims and pulleys must be regulated so that they will give the desired
speed to the spindles when on the third or slowest speed.
A modification of my invention is shown in Figs. 10. 11. 12 and 13. sheet 2. and
consists in a modification of the way in which the shaft h is driven, and in the
application of a device for controlling the action of the click catch j³.
Instead of the shaft being driven as previously described from the counter shaft k²
I secure a grooved pulley p¹ to the rim shaft n. On the shaft h instead of the two
pulleys and I mount a grooved pulley p² which is free to revolve on the shaft h.
This pulley receives motion by means of the band p from the pulley p' secured
to the rimshaft n. The tension of the band p is regulated by the tightening
apparatus. Secured to the shaft is the ratchet wheel j. Secured to the
pulley p² is a stud; which carries the click catch . The boss of the click
wheel is provided with a groove 3 to receive the click spring one end of which
is connected to the click catch in the ordinary well known manner. The click
catch is also provided with a projecting stud 7 which is capable of being acted
upon by a circular plate 7 which is mounted upon the shaft h. The boss of this
plate is provided with a groove je to receive the forked ends of the lever by
means of which the plate can be slidden on the shaft h the plate being free to
rotate on the shaft. The edge of this plate 17 is inclined or "conical" to the axis of
the shaft h and at the proper time acts upon the projecting stud j of the click catch j³
so as to keep the click catch out of gear with the teeth of the click wheel j. The
lever which operates the plate j' is connected to the vertical rod by a swivel
joint. The lower end of the vertical rod is by means of the joint 1 and a stud n²
connected to the strap-lever n. The hangers and see Figs. 10 and 11, sheet 2,
are provided with projecting parts and . To the part is secured the tightening
apparatus for regulating the tension of the band p. To the part 7 is secured the
tightening bracket which is for the same purpose as the brackets 2 in Figs. 1 and 2.
The other parts employed are shown on sheet 1.
The action of the parts is as follows:-When the operation of the "backing off"
has been performed and the mule carriage is making its inward run the part 63 of the
friction clutch will be geared with the part b. When the carriage during its inward
run arrives at the position which brings the anti-friction bowl in contact with
the inclined end e¹ of the rail e the tumbler lever f¹ will turn on its axis by
overcoming the elasticity of the spring f which will permit the anti-friction
bowl to slide along the rail e until it passes over and beyond the inclined
end without having caused the lever d¹ to move in the direction indicated by
the arrow ethus permitting the friction clutch to remain in gear. When the
carriage arrives at the end of its inward run the automatic action of the self-
acting mulo which is well understood will by means of the "cam shaft changes” cause

page_text: the driving belt n' to bo traversed from the loose pulley 4 on to the slow speed
pulley when motion will be communicated to the rimshaft n°. At the same time the
vertical rod will be pulled down and cause the plate to be moved out of contact
with the projecting stud 6 of the click catch j³ to allow the catch to act. The rotation
of the rimshaft n will communicate motion by means of a train of gearing to the
rollers and drawing out motion of the carriage. The "tin roller" shaft. c will receive
motion from the "rim" n' through the rim band a and the spindles will be driven at
the slow or normal speed. The rotation of the "tin roller" shaft c will at the same
time by means of the pulley c and additional rim band g communicate motion to the
shaft h. At the same time the pulley p' on the rimshaft n will have communicated
motion to the pulley p² mounted on the shaft h by means of the band p. The click
catch secured to the pulley p² would at once gear with the teeth of the ratchet
wheel if it were not for the fact that the ratchet wheel is already revolving at a
greater velocity than the pulley p² which carries the click catch j³.
When the carriage is moved a short distance on its outward run this distance being
capable of being regulated at pleasure, the anti-friction bowl will come in contact with
the inclined end e² of the rail e. The further movement of the carriage will cause the
anti-friction bowl to "ascend" the inclined end e² of the rail e and force
the tumbler lever to which it is secured in the direction indicated by the arrow e³
and in so doing will by means of the lever d' disengage the two parts b and 63 of
the friction clutch when the "tin roller shaft" c will cease to receive motion from the
rim band a and being no longer driven loses its velocity and with it the speed of the
shaft is reduced until its velocity is less than the velocity of the pulley p² when
the click catch engaging with the click wheel will drive tho shaft h and by means
of the rim g', band g and pulley c¹ will give motion to the "tin roller" shaft c and so
drive the tin roller and spindles at a reduced or slowest velocity.
The further outward movement of the carriage will cause the anti-friction bowl f
to arrive at the incline e' at the other end of the rail e which permitting the end of
the lever to move in the direction contrary to that indicated by the arrow e will
by means of the spring c and d cause the parts 63 and 6 of the friction clutch to be
re-engaged which at once causes the "tin roller" shaft c to be again driven by the
rim band a at the "slow" or "normal" speed.
The increased velocity of the tin roller shaft c will by means of the band
the shaft and click wheel 2 to "overrun" the click catch when the band
cease to drive the spindles.
g cause
will
The further outward run of the carriage, the engagement of the double speed
motion, the necessary changes to cause the "backing off" to take place, and the
carriage to make its inward run, will be performed as usual.
When the strap-lever n moves the belt n' from the slow speed pulley n³ to the quick
or double speed pulley no the vertical rod connected to the strap lever n will cause
the circular plate to pass under the projecting stud 1 of the click catch ³ in order
to prevent this click catch from gearing in the teeth of the click wheel 2. When
the belt n' is moved from the pulley n to the loose pulley n' to allow the " backing
off" to take place the circular plate is still kept under the projecting part
remains in this position during the inward "run" of the carriage so as not to
interfere with the winding. The manner of adjusting and regulating the
" slowest
speed" is the same as the other arrangement previously described.
and
My improvements have been described as being applied to a mule which spins on
the woollen system with "double speed," but I would have it understood that my
improvements are equally applicable to mules with "single speed" whether used for
spinning cotton, wool, or other fibrous substances.
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
