Improvements in Self-acting Mules and Twiners.
I, ROBERT CLEGG, of Soho Iron Works, Oldham, in the County of Lancaster,
Foreman of Mule Room, do hereby declare the nature of this said invention and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
My invention consists in an automatic cop bottom governing motion for self-acting
mules and twiners and the chief object of my invention is to render the strapping
motion reliable and automatic in its action and at the same time to prevent the counter
faller wire from descending too far bolow the spindle point at any time while the yarn
is being wound on during the inward run of the carriage whereby the quadrant nut
is caused to ascend in exactly the same ratio as the bottoms of the cops increase in
circumference and thus sound bottoms free from snarls are produced.
I carry my invention into effect by fixing on the winding faller shaft a toothed
segment which gears into a pinion fixed on the axis of a chain pulley or eccentric
block to which is secured one end of a chain or equivalent which. pusses over a carrier
pulley mounted on the strapping lever and is attached at the other end to the counter
faller finger.
And in order that my invention may be fully understood and readily carried into
effect I will describe the same with reference to the accompanying Sheet of Drawings
which shows in side sectional elevation part of a mule carriage to which my invention
is applied.
In this Drawing a designates the mule carriage, the spindles, the winding
faller shatt, c' the winding faller finger, d the counter faller shaft and the counter
fuller finger, e the weighted strapping lever fulcrumed on the carriage end at a¹ and
el the usual catch on the strapping lever e, f the strapping band which passes as usual
over the band pulley g fixed on the shaft of the star wheel h and also over the band
pulley fixed on the quadrant shaft j returning under and over the carrier or guide
pulleys to the band pulley g; 1 is the quadrant and the quadrant arm, m the
quadrant nut and m² the quadrant chain and "m" the screw the latter being turned by
a pair of bevels from the quadrant shaft j to regulate the position of the quadrant
nut m in the ordinary manner.
All the above parts are or may be of the usual construction and operate in the
ordinary way.
For the purposes of my invention I fix on the winding faller shaft
c, a toothed
segment n which gears into a pinion o fixed on a stud p on which is also fixed a chain
pulley y or it might be an eccentric block. To the periphery of the pulley 9 is
fastened one end of a chain which passes under a carrier pulley s mounted on the
strapping levere and is attached at the other end to an adjustable hook t carried on
the counter faller finger d'. When the winding faller finger c¹ descends, the
segment n turns the pinion o and so unwinds a portion of the chain from the
pulley . At the commencement of winding a set of cops the winding faller finger c¹
descends to its lowest point and will in consequence turn the chain pulley 7 the
greatest distance and thus unwind the most chain. As the cop bottoms gradually
increase in length the descent of the winding faller finger c¹ gradually decreases in
the same ratio thereby causing the chain pulley q to unwind less chain at every draw.
This shortening of the chain causes the counter faller finger d' to descend a little
lower every draw before it reaches the point at which through the lowering of the
strapping lever e the catch el engages the star wheel thereby stopping its rotation
and that of the band pulley g while the continued inward movement of the carriage
pulls the strapping band and winds up the quadrant nut as is well understood.

The toothed segment n heing fixed on the winding faller shaft and the chain » being
attached to the counter faller finger dit follows that the setting of the fallers also
sets the governing motion.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. Regulating automatically and positively by toothed gearing from the winding
faller shaft the length of a chain or equivalent which is connected to the counter faller
finger and passes under a carrier on the strapping lever to a chain pulley or eccentric
actuated by the said toothed gearing for the purposes specified.

2. The combination with the strapping lever e, the carrier & the chain » attached
at one end to the counter faller finger and at the other to a chain pulley or eccentric
fixed with the pinion o, of the toothed segment fixed on the winding faller shaft c
all substantially as and for the purposes specified.
