PROVISIONAL SPECIFICATION.
Improvements in Self Acting Mules and Twiners.
We, ROBERT CLEGG, Foreman of Mule Department, and JOHN HOLT, Mule
Erector, both of Soho Iron Works, Oldham, in the County of Lancaster, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to self acting mules and twiners and consists in an improved
arrangement of mechanism for easing the yarn during the backing off operation,
and for allowing the weight of the salmon head levers to go on gradually and
smoothly at the commencement of the inward run.
In carrying our invention into effect we fit an arm or bracket loosely on the
counter faller. shaft on which shaft we also fix another curved arm or elbow lever;
we connect the first arm to the elbow lever by means of a spring the tension of
which can be adjusted by a screwed stud and wing nut or any other suitable device.
On the headstock we fix an adjustable incline upon which the end of the first arm
or a bowl thereon mounts as the carriage approaches the end of the outward run,
and thereby extends the spring which connects the said arm to the curved arm or
elbow lever; consequently the spring offers a certain resistance to the rise of the
counter faller and so renders its action smooth and steady. As the carriage
commences its inward run the end of the first arm or the bowl thereon as the case
may be gradually leaves the incline and allows the weight of the salmon head
levers to come on smoothly and gradually.
Instead of placing the incline on the headstock we may fix it adjustably on the
floor, and suspend a rod or lever from the first arm or bracket; this rod or lever
would be guided by a bracket on the mule carriage, and its lower end or a bowl
thereon would come in contact with the incline and so actuate the first arm or
bracket as described.

COMPLETE SPECIFICATION.
Improvements in Self Acting Mules and Twiners.
We, ROBERT CLEGG, Foreman of Mule Department, and JOHN HOLT, Mule
Erector, both of Soho Iron Works, Oldham, 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 self acting mules and twiners and consists in an improved
arrangement of mechanism for easing the yarn during the backing off operation,
and for allowing the weight of the salmon head levers to go on gradually and
smoothly at the commencement of the inward run.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Fig. 1 represents a side sectional elevation of part of a mule carriage fitted with
our improved arrangement of mechanism for easing the yarn when backing off and
Fig. 2 is a similar view of an alternative arrangement according to our invention.
In these views,-a designates the mule carriage, one of the spindles, c the
counterfaller shaft, c' the counterfaller sickle, d the faller shaft and its faller
sickle.

page_text: .
In the arrangement illustrated by Fig. 1 we fit an arm or bracket e loosely on
the counterfaller shaft c on which shaft we also fix another curved arm or elbow
lever f; we connect the arm e to the curved arm or elbow lever by means of a
spring g the tension of which can be adjusted by means of a screwed stud g' and a
wing nut which bears upon the upper side of the arm e or by any other suitable
device.
To the free end of the arm e is pivoted a rod or lever which passes through
and is guided by a bracket i secured to the mule carriage a and to the foot of this
rod his secured adjustably a bracket j with a curved foot, which when the carriage
approaches the end of its outward run, comes upon and mounts an incline k secured
adjustably at ¹ to a bracket 1 secured to the floor; as the curved foot of the
bracket rises on the incline it lifts the rod h which at the same time pushes the
arm e upwards thereby extending the spring g which tends to turn the counterfaller
shaft c and pull down the counterfaller c¹ thus offering a certain resistance to the
rise of the counterfaller c¹ and so renders its action smooth and steady.
As the carriage a commences its inward run the curved end of the bracket j
gradually leaves the incline k and allows the weight of the salmon head levers
(which are not shown) to come on to the yarn smoothly and gradually.
We prefer to place the incline k upon the floor but it might be mounted on the
headstock of the mule in which case the end of the arm e or a bowl thereon (the
arme being suitably shaped) would mount the incline as the carriage approached
the end of the outward run, the action being the same as in the arrangement above
described.
In the alternative arrangement illustrated by Fig. 2 a curved lever
fulcrumed on the stud p on which is also fulcrumed the ordinary weight or
salmon head lever o, the stud p being supported in a bracket r secured to the mule
carriage a. The salmon head lever o is connected to the curved lever 7 by a
spring g and is also connected in the ordinary way by a chain n to a half moon
bracket m on the counterfaller shaft c. The lever comes upon and mounts the
incline as the carriage approaches the end of its outward run and extends
the spring g thereby easing the action of the salmon head lever o and allowing the
weight to go on gradually and smoothly at the commencement of the inward run.
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 with an arm loose upon the counterfaller shaft and connected
by a spring to an arm fixed upon said shaft, of an incline acting either directly or
through suitable connections upon the loose arm so as to ease the yarn during the
backing off operation and to allow the weight of the salmon head levers to go on
gradually and smoothly at the commencement of the inward run substantially as
herein set forth.
2. The combination with the salmon head lever and an incline fixed adjustably
on the floor, of a curved or otherwise suitably formed lever connected to the
salmon head lever by a spring and arranged so as to travel on the incline
substantially in the manner and for the purposes herein set forth.
3. The combination and arrangement of parts substantially as and for the
purposes herein described and as illustrated by Fig. 1.
4. The combination and arrangement of parts substantially as and for the
purposes herein described and as illustrated by Fig. 2.
