PROVISIONAL SPECIFICATION.
Improvements in Self-acting Mules for Spinning Wool, applicable
also to Spinning Cotton and Waste.
We, ASA LEES AND COMPANY LIMITED, of Soho Iron Works, Oldham, in the
County of Lancaster, Machine Makers, and JOHN CLEGG, of the same address,
Manager of the Mule Department, do hereby declare the nature of this invention
to be as follows:-
--
Our invention relates to improvements in self acting mules for spinning wool,
applicable also to spinning cotton and waste, and it is designed for the purpose of
catching or taking hold of broken ends of yarn and winding them on a roller which
is arranged to break them off at any required moment thus preventing the minder
from piecing the ends up and making yarn of courser counts and varying twist.
The roller also prevents the ends from falling on the floor and getting soiled.
In carrying our improvements into effect we mount a roller in bearings on the
mule carriage near the back and we drive this roller for a short time by any suit-
able means after the carriage has gone a certain distance during each outward run
or draw. If an end breaks after the carriage has got so far out that to piece it
up would cause a fault in the yarn it is caught and wound on by the roller (which
will then be rotating) and is broken off at the nip of the drawing rollers, and this
will be repeated at the next and each subsequent outward run should the minder
fail to piece up the end at the proper time. We may drive the thread catching
roller intermittently by a rack and pinion or any other suitable means for example,
a convenient arrangement for the purpose consists of a fluted or other suitably
shaped roller fixed on a short shaft carried by the carriage and on this short shaft
is also fixed a pulley connected by a band to a pulley on the thread catching roller
axle. We stretch a belt of leather or other suitable material in a bracket secured
adjustably on that part of the framing commonly called the out end." As the
carriage travels outward the fluted roller comes into contact with the leather belt
and is rotated thereby and by the pulleys and band rotates the thread catching
roller until the continued outward movement of the carriage takes the fluted roller
beyond the belt.

We, ASA LEES AND COMPANY LIMITED, of Soho Iron Works, Oldham, in the
County of Lancaster, Machine Makers, and JOHN CLEGG, of the same address,
Manager of the Mule Department, 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 for spinning wool,
applicable also to spinning cotton and waste, and it is designed for the purpose of
catching or taking hold of broken ends of yarn and winding them on a roller which
is arranged to break them off at any required moment thus preventing the minder
from piecing the ends up and making yarn of courser counts and varying twist.
The roller also prevents the ends from falling on the floor and getting soiled.
In carrying our improvements into effect we mount a roller in bearings on the
mule carriage near the back and we drive this roller for a short time by any suit-
able means after the carriage has gone a certain distance during each outward run
or draw. If an end breaks after the carriage has got so far out that to piece it
up would cause a fault in the yarn it is caught and wound on by the roller (which
will then be rotating) and is broken off at the nip of the drawing rollers, and this
will be repeated at the next and each subsequent outward run should the minder
fail to piece up the end at the proper time.
In the accompanying sheet of drawings:-
-
Fig. 1 is a side elevation of part of the mule carriage and "the out end" of the
mule frame to which our improvements are applied and Fig. 2 is a plan view of
Fig. 1.
In these views, a is a portion of the mule carriage and b a portion of the "out
end" of the mule framing; at the back of the carriage are fitted suitable bear-
ings c which support the axle of a thread catching roller d which is driven at a
certain portion of the outward run of the carriage by a band e which passes over a
grooved pulley f on the axle of the roller d and a similar pulley g mounted upon a
stud secured to the carriage side; to the pulley 9 is secured a small fluted or
other suitably shaped roller i which as the carriage is making its outward run comes
into frictional contact with the leather covered or other suitably prepared surface j
of a bracket & secured adjustably to the "out end" of the mule framing.
When the mule is in operation the thread catching roller d remains at rest until
the roller comes into contact with the leather surface j, and as the carriage con-
tinues its traverse the roller i is caused to rotate and its rotation is imparted by the
pulley g, band e and pulley f to the thread catching roller d which continues to
rotate so long as the roller i is in contact with the leather surface j, and is stationary
whenever the roller i is not in contact with the leather surface j. If an end of yarn
breaks after the carriage has travelled so far out that to piece it would cause a fault
in the yarn, it is caught by the then rotating roller d and wound on it, and the
yarn is broken off at the nip of the drawing rollers, and this will. be repeated at
the next and each subsequent outward run of the carriage should the minder fail
to piece up the end at the proper time.
We may drive the thread catching roller d intermittently by a rack and pinion
or by any other suitable means.
In the arrangement illustrated in the drawings the roller d will be caused to
rotate also as the carriage runs in, this could if desired be obviated by connecting

page_text: the roller i to the pulley f by a pawl and ratchet wheel or other equivalent arrange-
ment.
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 arrangement, use and application of a thread catching roller mounted
upon the mule carriage and driven intermittently for the purposes of catching and
winding on any broken ends of yarn and breaking off such ends at the nip of the
drawing rollers substantially as and for the purposes described.
2. The general arrangement and combination of parts forming the improved
thread catching device substantially as and for the purposes described.
