We, WILLIAM HEATON of Lostock Mill, Cotton Spinner,, and JOHN CATTERALL
of 30 Heaton's Road, Overlooker, both of Lostock Junction near Bolton in the
County of Lancaster, do hereby declare the nature of our Invention for "IMPROVE-
MENTS IN APPARATUS EMPLOYED IN MULES FOR SPINNING," to be as follows:--
*
Our invention relates to improvements in apparatus employed in mules for
spinning and is designed for the purpose of maintaining the tension of the rim
band under all conditions of working to prevent slip and dispense with the
inconvenience of unequal twist in yarn.
To the headstock of the mule is attached a stationary fixing provided with
suitable angular or other slides in which a metallic carriage is mounted, the latter
being provided with bearings to carry the back rim band pulley. To each end of
the stationary fixing are disposed suitable pins or centres on which are mounted
a sliding lever with angular or other slots at each end; the centre part having
a straight slot to admit a stud or pin attached to a swinging catch mounted on the
side of the metallic carriage and to allow of the sliding action of the same.
When the mule carriage is moving outwardly the sliding lever is raised on the
pins or centres by the angular or other slots disposed therein, which lifts the catch
on the side of the aforesaid metallic carriage out of action with a ratchet on the
bed of the stationary fixing, thus allowing the metallic carriage to move according
to the stretch or tension on the rim band, the movement being effected by a
weight attached to the opposite end of the rim band carriage by a band or other
equivalents, and guided to any convenient position over guide pullies, thus, if the
rim band stretches it is compensated for by the weight moving the carriage
backwards according to the increase in length...
When the mule backs off the sliding lever is operated by a rod or other
equivalents from the carriage of the mule, or by one of the change levers in the
headstock, with the result of dropping the sliding lever and the catch on the back
rim band pulley carriage, thereby locking and firmly holding the same to overcome
the increased strain on the rim band..
By the application of this invention the back rim band pulley becomes
adjustable and compensates for the stretching of the rim band and the changing of
rim pullies to accomodate the various counts being spun.

We, WILLIAM HEATON of Lostock Mill, Cotton Spinner, and JOHN CATTERALL
of 30 Heaton's Road, Overlooker, both of Lostock Junction near Bolton in the
County of Lancaster, do hereby declare the nature of our said Invention for
*IMPROVEMENTS IN APPARATUS EMPLOYED IN MULES FOR SPINNING," 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 apparatus employed in mules for
spinning and is designed for the purpose of maintaining the tension of the rim
band under all conditions of working to prevent slip and dispense with the
inconvenience of unequal twist in yarn.
Fig. 1 is an end view of our improved apparatus for maintaining the tension of
the rim band employed in mules for spinning-Fig. 2 is a right hand side elevation
of Fig. 1 shewing the position of the apparatus when the mule backs off-Fig. 3
is a left hand side elevation of Fig. 1 shewing the position of the apparatus when
the mule carriage is making the outward run-Fig. 4 is a part plan of Fig. 3 and
Fig. 5 is a part sectional elevation through line A¹ B' in Fig. 2.
The stationary fixing A is provided with the sliding surfaces B on which the
carriage C is mounted; the latter being provided with the bearings D in which is
mounted the back rim band pulley E. The stationary fixing A can be attached in
any convenient way to the headstock F of the mule, or to the mule room floor, as
shewn, by the fixing G. To each end of the stationary fixing A are disposed the
pins or centres H on which is mounted the sliding lever I provided at each end
with the angular slots I. The sliding lever I is provided with the slots I which
admits the stud or pin J attached to the "pawl" or swinging catch K mounted on
the side of the carriage C, the slot I allowing of the sliding action of the same.
The carriage C is provided with the projections S which fit and slide in and on
the sliding surfaces B as in Fig. 5, being secured in position by the plate T; the
latter being secured by the set screws U.
This apparatus operates as follows:-Before the mule carriage commences to
make an outward run the sliding lever I is raised on the pins or centres H, as in
Fig. 3, by the lever L attached to the catch box shaft M mounted in the headstock,
which lifts the "pawl" or swinging catch K on the side of the back rim pulley
carriage C out of action with the ratchet N on the stationary fixing A, thus
allowing the carriage C to move according to the stretch or tension on the rim
band O, which movement.is effected by the weight P attached to the opposite end
of the carriage C by the band Q, the latter being guided over the guide pulley R
mounted on the back of the headstock F. Should any slack or stretch take place
in the rim band O-the weight P immediately operates the carriage C in proportion
to the increased length.
When the mule carriage backs off the action of the sliding lever I is reversed by
the lever L mounted on the catch box shaft M, by which it is dropped as in Fig. 2
with the result of placing the "pawl" or swinging catch K in gear with the
ratchet N, thereby locking the back rim band pulley and carriage to overcome the

page_text: increased strain on the rim band O, at which point it remains until released by
the lever L when the mule carriage is ready to commence its next outward run.
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:-
The construction, combination, and arrangement of parts forming our improved
apparatus for maintaining an uniform tension on the rim band employed in mules
for spinning, applied and operating substantially in the manner described and as
shewn on the drawings.
