PROVISIONAL SPECIFICATION.
Improvements in or relating to Mules for Spinning.
We, THOMAS PILKINGTON of 51 Oxford Grove, Overlooker, and PETER
BOARDMAN of 21 Norman Street, Spinner, both of Bolton in the County of
Lancaster, do hereby declare the nature of our said invention to be as follows:-
This invention refers to improvements in or relating to mules for spinning cotton
and other fibrous substances, and has for its object the easing of the action of the
underfaller when the mule carriage is making an inward run, by which snicks,
snarls, and cut yarn are reduced to a minimum, and larger and better cops are
produced than hitherto. The underfaller is provided with a lever which operates
on a pin attached to a rod loosely mounted in bearings on the headstock of the
mule. To the rod is attached a spring, weight, or other equivalents, which can.
be adjusted in tension or weight according to the various counts being spun or
otherwise. When the mule carriage has almost completed its inward run the
lever on the underfaller operates on the pin on the loosely mounted rod, and
causes the underfaller to drop gradually and evenly, thereby relieving the latter
from undue or sudden strain, resulting in a better and more perfect yarn being
produced than hitherto. By this invention the working of the mule is con-
siderably enhanced throughout owing to its being relieved of the sudden shock
caused by the present system of employing a fixed stop for the underfaller.

Improvements in or relating to Mules for Spinning.
We, THOMAS PILKINGTON of 51 Oxford Grove, Overlooker, and PETER
BOARDMAN of 21 Norman Street, Spinner, both of Bolton in the County of
Lancaster, do hereby declare the nature of our said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention refers to improvements in or relating to mules for spinning
co ton and other fibrous substances, and has for its object the easing of the
action of the underfaller when the mule carriage is making an inward run, by
which snicks, snarls, and cut yarn are reduced to a minimum, and larger and
better cops are produced than hitherto. The underfaller is provided with a lever
which operates on a pin attached to a rod loosely mounted in bearings on the
headstock of the mule. To the rod is attached a spring, weight, or other
equivalents which can be adjusted in tension or weight according to the various
counts being spun or otherwise. When the mule carriage has almost completed
its inward run the lever on the underfaller operates on the pin on the loosely
mounted rod, and causes the underfaller to drop gradually and evenly, thereby
relieving the latter from undue or sudden strain, resulting in a better and more
perfect yarn being produced than hitherto. By this invention the working of
the mule is considerably enhanced throughout owing to its being relieved of the
sudden shock caused by the present system of employing a fixed stop for the
underfaller.

stock of a mule.

headstock of a mule, and
Fig. 4 is a side elevation of another modification of our invention operated from
an incline fixed on mule room floor.
In all the figures the same letters are employed to indicate corresponding
parts.
A is the headstock of a mule; B the copping faller; C the underfaller, and D the
mule carriage. The underfaller C is provided with the lever E, which operates
on the pin G mounted on the lever Ĥ. The latter is pivoted on the centre F
secured to the fixing I as in Figs. 1 and 2, or, to the headstock A as in Fig. 3.
The lever H is also provided with the arm J, in which is placed the adjusting
screw K to operate on the top side of headstock A as in Figs. 1 and 2, or, on
support or stop U on-side of headstock A as in Fig. 3. The screw Kis..
employed for adjusting the position of the lever H according to the point at
which it is necessary for the lever E to operate on the pin & when the mule
carriage D is completing its inward run. The upper end of the lever His
forked to allow of rod M to pass through when operating on the washer Nto
depress the spring or springs O on the said rod. The rod M is mounted in the
fixing P secured to the headstock A. The movable washer Q on the rod M is
fitted with the set screw R for the purpose of adjusting the power of the spring.
or springs according to the counts of yarn being spun. The middle washer,S.
can be loosely mounted on the rod M between the springs O as in Fig. 3, or,
it can be provided with a set screw as shown in dotted lines in Fig. 1 so that
the front spring O can be increased or decreased in power according to circum-
stances.
The underfaller rod C is coupled to the mule carriage by the arms T or
other fixings in the usual manner.
When the mule carriage has almost completed its inward run the lever E on
the underfaller C operates on 'the pin G on the lever H and compresses the
spring or springs O until the lever H is arrested by the stop U fixed to the
headstock A, which action causes the underfaller wire to drop gradually and
evenly, and eases the yarn from undue strain in the most vital part of its
manufacture, also reduces the amount of waste to a minimum, thereby dispensing
with many sources of complaint, a desideratum of great importance to cotton
spinners and others connected with the trade.
In the modification shown in Fig. 4 in the annexed drawings the lever Eis
mounted on the underfaller rod C, and is connected to the pivoted lever H by
means of the spring O. The lever H is fitted with the bowl V, which, as the
inule carriage D is completing its inward run, slides up the incline W fixed, on
the mule room floor, and gradually and evenly pulls down the underfaller wire
by means of the spring O, and relieves the yarn being spun from undue strain
and sudden shock.
This invention eases the action of the underfaller wire on the yarn when the
mule carriage is completing its inward run, by which snicks, snarls, and cut
yarn are entirely obviated, and larger and better cops are produced than hitherto.
An important feature of this invention is that it produces an uniform tension, on
the yarn throughout the entire length of the mule, thus relieving the yarn being.
spun from strain and prevents the ends breaking and being wound as loose.

This invention can be applied to the depression lever from which, the under-
faller rod is operated, by which a considerable gain will be effected with a
reduced draught of the rollers.
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. In mules for spinning, cotton and other fibrous substances automatically

page_text: easing the action of the underfaller wire on the yarn when the mule carriage
is completing its inward run, substantially as described and for the purposes
specified.
2. The combinations and arrangements of parts constituting our improved
easing motion for relieving the yarn from undue strain by the action of the under-
faller wire when the mule carriage is completing its inward run, substantially
as and for the purposes herein described and as shown in the drawings.
