in the County of Lancaster, WILLIAM HAYTHORNTHWAITE, Manager, and WILLIAM
TEMPEST, Engineer, both of Cherry Tree, near Blackburn, aforesaid, do hereby
declare the nature of this invention to be as follows;-
Our invention relates to improvements in self acting mules and the object of
our improvements is to spin good and firm cop noses and this we effect by putting
a certain amount of tension on the backing off chain while the nose of the cop is
being formed.
In carrying out our invention we employ the usual backing off chain secured
at one end to an arm or sector on the copping faller shaft and at the other end to
the ordinary backing off scroll or snail which is mounted loosely upon the
tin roller shaft or drum shaft. We also employ the ordinary
click or ratchet wheel
on the same shaft with its spring click or pawl
carried as usual by a stud bolted to the rim or flange of the backing off scroll
or snail, and in combination with these parts we secure an adjustable stop or
finger, on the shaper rod, rail or plate and we pivot to any convenient part of
the carriage square an elbow lever with its end in the path of the stop piece; we
also employ an arm which is arranged to clasp loosely the boss of the click wheel,
the snail, or it might be the tin roller shaft and this arm rests normally upon a
bent arm secured to the other end of the elbow lever before mentioned.
The apparatus is set so that the tension is put on the backing off chain at any
desired point in the building of the cop by adjusting the position of the stop
on the shaper rod, rail or plate; when the shaper rod has moved far enough and
this stop meets the elbow lever and moves it, the bent arm carried by the elbow
lever raises the arm pivoted on the tin roller shaft and this arm coming against
the stud of the spring click moves it and the snail partly round and so puts the
desired tension on the chain; the stop will continue to move the elbow lever at
every draw and the click will be gradually caused to enter earlier into a new
tooth fhus putting a gradually increasing tension on to the backing off chain
during and until the completion of the cops.

page_text: We, JOSEPH DUGDALE, Junior, Cotton Spinner, of Paradise Mill, Blackburn,
in the County of Lancaster, WILLIAM HAYTHORNTUWAITE, Manager, and WILLIAM
TEMPEST, Engineer, both of Cherry Tree, near Blackburn, aforesaid, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement;
Our invention relates to improvements in self acting mules and the object of
our improvements is to spin and wind good and firm cop noses and this we effect
by putting a certain amount of tension on the backing off chain while the nose
of the cop is being formed.
In the accompanying sheet of drawings-
Figure 1 is a sectional elevation of as much of a self acting mule as is.necessary
for the illustration of our improvements.
Figure 2 is a plan view of Fig. 1.
In carrying out our invention we employ the usual backing off chain 1 secured
at one end to an arm or sector 2 on the copping faller shaft 3, and at the other
end to the ordinary backing off scroll or snail 4 which is mounted loosely upon
the tin roller shaft 5. We also employ the ordinary click or ratchet wheel 6
which is fast on the same shaft, and has its spring click or pawl 7 carried as
usual by a stud S bolted to the rim or flange 9 of the backing off scroll 4.
In combination with the foregoing parts we secure an adjustable stop or
finger 10 on the shaper rod 11, and we pivot at 12 to any convenient part of the
carriage square 13 an elbow lever 14 with its pendant end lying in the path of
the stop piece 10; we also employ an arm 15 which is arranged to clasp loosely the
boss of the screll or click wheel 6 and this arm rests normally upon a bent arm 16
secured to the end of the elbow lever 14.
The click or pawl 7 is held normally out of gear with its ratchet wheel 6 by
means of a spring 17 which is leather lined and grips the boss of the ratchet wheel
so as to obtain the necessary frictional resistance to the free movement of the
spring.
During the outward run of the carriage and whilst twisting is taking place the
click 7 is held by the spring 17 out of gear with the ratchet wheel 6 but just as
backing off is about to begin the pendant end of the elbow lever 14 coming into
contact with the stop piece 10 on the shaper rod, rail or plate is thereby moved
and by the bent arm 16 raises the arm 15 pivoted on the tin roller shaft and this
arm coming against the stud 8 moves the spring click 7 and the snail partly
round, the click 7 being put into gear with the ratchet wheel 6 by the spring 17
and as the ratchet wheel begins to turn in the reverse direction the backing off
chain is wound upon the snail.
The position of the stop piece 10 changes at each draw as the cops gradually
increase in size and so the elbow lever 14 is moved gradually more and more and
the click 7 and snail 4 are thereby moved further back at each draw thus causing
the click to enter earlier into gear with the ratchet wheel which consequently
winds more chain upon the snail and so puts a gradually increasing tension on to
the backing off chain at each draw until the cops are completed.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. The combination with the backing off chain its scroll or snail loose on the

page_text: tin roller shaft, the ratchet wheel fast on the tin roller shaft, and its spring click,
of an elbow lever actuated at each draw by an adjustable stop on the shaping
mechanism and connections from the said elbow lever for varying the position of
the spring click so as to tighten the backing off chain as the cops gradually
increase, all substantially as herein set forth.
2. The general combination and arrangement of parts substantially as herein
set forth.
