PROVISIONAL SPECIFICATION.
Improvements in Self Acting Mules and Twiners.
We, JOHN CLEGG, Manager of Mule Department, of Asa Lees and Company
Limited, of Soho Iron Works, Oldham, JAMES LORD, Mill Manager, of 37 Upper
George Street, Tyldesley, and THOMAS WILSON, Mule Overlooker, of 23 Thomas
Street, Atherton, all in the County of Lancaster, do hereby declare the nature of
this invention to be as follows:-
Our invention relates to improvements in self .acting mules and twiners and the
object of our invention is to prevent the formation of snarls on the spindle blades
caused ordinarily by the irregular upward movement of the winding faller wire.
We accomplish this object by the use and application of. an arrangement of
automatic mechanism which insures a gradual and smooth rise.of.the winding faller
throughout the entire build of the cops.
For example we employ say one bracket secured to the winding faller shaft and
we mount upon the mule carriage a stud in line with such bracket. On the stud is
fitted a ratchet wheel or equivalent with a boss or small pulley on each side of the
teeth; a pawl is pivoted so as to gear into the ratchet wheel and the tail end of
this pawl is connected by a chain or equivalent to the boss of the bracket on the
faller shaft. One portion of this bracket is connected by a chain or the like to the
outside boss of the ratchet wheel and on the opposite end of the bracket and
equi-distant from the faller shaft is mounted a swivel arm which is connected by a
chain or equivalent and an adjustable spiral spring to the boss.on the other. side of
the ratchet wheel.
In operation when the winding faller goes down the movement causes the
bracket to draw up and unwind its chain from the pulley and simultaneously wind
up the chain, attached to the spring the pawl allowing the pulley to turn in this
direction; but when the motion of the faller shaft is reversed the faller rises and
the pawl holds the ratchet wheel and double pulley stationary, the movement of
the faller shaft and bracket charges the spring until the faller wire arrives about
level with the top of the spindles and then the further upward movement of the
faller lifts the pawl out of the teeth of the ratchet wheel and the spring being
liberated collapses and turns back the double pulley and re-sets both chains.
Any suitable equivalent for the ratchet wheel and. pawl may be employed as for
example a grooved pulley and a pivoted lever its end shaped to fit the groove and
held in contact with the pulley by a spring.
This mechanism is automatic since as the cops increase in: length the movement
of the winding faller decreases and therefore the spring is.automatically charged
less and less in proportion to the decrease in the movement of the faller.

We, JOHN CLEGG, Manager of Mule Department, of Asa Lees and Company-
Limited, of Soho Iron Works, Oldham, JAMES LORD, Mill Manager, of 37 Upper
George Street, Tyldesley; and THOMAS WILSON, Mule Overlooker, of 23 Thomas
Street, Atherton, all in the County of Lancaster, 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:-
Our invention relates to improvements in self acting mules and twiners and the
object of our invention is to prevent the formation of snarls on the spindle blades
caused ordinarily by the irregular upward movement of the winding faller wire.
We accomplish this object by the use and application of an arrangement of
automatic mechanism which insures a gradual and smooth rise of the winding faller
throughout the entire build of the cops.
In the accompanying sheet of drawings-

Figure 1 is an end sectional elevation and Figure 2.a side elevation of part of a
'self acting mule or twiner illustrating the application of our improvements thereto.
In these views, a designates the counter faller shaft and b the copping or
winding faller shaft on which we secure a bracket c, and d is a stud mounted on
the mule carriage e about in line with the bracket c. On the stud d is fitted a
ratchet wheelf with a boss or small pulley f f respectively on each side of the
teeth; to the carriage e is bolted a bricket g to which is pivoted at g' a pawl h in
gear with the ratchet teeth f; one side of this pawl is connected by a spring i to an
arm of the bracket g and the tail end of the pawl is connected by a chain or
equivalent to the boss of the bracket e on the faller shaft b. An arm of the
bracket is connected by a chain k or the like to the boss f' of the ratchet wheel f
and on the opposite end of the bracket c is mounted a swivel arın m which is
connected by a spiral spring n (adjustable by a hooked rod o and wing nut p) and
a chain or equivalent g to the boss 2 on the other side of the ratchet wheel.

In operation when the winding faller goes down the movement causes the
bracket to draw up and unwind its chain k from the pulley and simul-
taneously wind up the chain q attached to the spring n, the pawl h allowing the
double pulley 1 to turn in this direction; but when the motion of the faller
shaft bis reversed the faller rises and the pawl h holds the ratchet wheelf and
double pulley ff stationary, the movement of the faller shaft b and bracket c
charges the spring n until the faller wire arrives about level with the top of the
spindles and then the further upward movement of the faller lifts the pawl h out
of the teeth of the ratchet wheelf and the spring n being liberated collapses and
turns-back the double pulley f¹ and re-sets both chains k and g.
Any suitable equivalent for the ratchet wheel and pawl / may be employed as
for example a grooved pulley and a pivoted lever its end shaped to fit the groove
and held in contact with the pulley by a spring.
This mechanism is automatic since as the cops increase in length the movement
of the winding faller decreases and therefore the spring is automatically charged
less and less in proportion to the decrease in the movement of the faller."
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The combination and arrangement of automatic mechanism substantially as
herein described with reference to the accompanying drawings for insuring a

page_text: gradual and smooth rise of the winding faller throughout the entire build of
the cops.
2. In combination, the ratchet wheel and double pulley mounted on the carriage
and connected to opposite sides of the winding faller shaft, and a spring pawl.
engaging the teeth of the ratchet wheel and preventing its movement and that of
the double pulley in one direction until the pawl is released by a connection from
the winding faller shaft and the parts are automatically re-set all substantially as.
and for the purposes herein set forth.
