PROVISIONAL SPECIFICATION.
Improvements in or relating to Mules and Twiners for Spinning.
We, JOHN ELLISON of 12 Elizabeth Street, Deane Road, Inventor, and
JOSEPH HALL of Glynn Street, Teacher of Cotton Spinning at Manchester
Technical Schools, 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 and twiners for
spinning cotton, wool, worsted, silk, and other fibrous substances and has for its
object that of depressing and easing the underfaller to prevent snicks, sparls,
breakage of yarn, soft noses, soft cops, and strained yarn. This we accomplish by
pivoting a lever to the back side of the mule carriage by means of a bracket or
fixing. On the front end of this lever is mounted a bowl or roller which runs or
slides up inclines placed on the mule room floor at each end of run of mule carriage.
The front end of lever is provided with a hole or slot through which passes and
Bwivels a rod hung from an arm or lever attached to underfaller rod. The upper
end of rod is screwed and provided with nuts; one of the latter having a hole to
receive the end of a spiral spring. The rod hung from the underfaller rod passes
through the spiral spring, and its lower end is secured to the front end of lever
pivoted to mule carriage. The pivoted lever is fitted with an arm and screw; the
latter operating against the bracket or fixing on the back side of the mule carriage.
The screw is provided for the purpose of taking the weight of lever off the
underfaller when the latter rises to a given point, and which may be adjusted so that
it will take the weight off the underfaller during the whole of the stretch when
starting to spin cops. This apparatus, when the mule carriage is completing an
outward run,
allows the bowl or roller to run or slide up the incline to take its own
weight off the underfaller gradually and then bears up by means of the spiral
spring to ease the same during the operation of backing-off. When the mule
carriage commences an inward run the spiral spring gradually allows the weight
to be imparted as the bowl or roller slides or runs down the incline when winding on
thick part of cop. When the mule carriage has almost completed its inward run
the bowl or roller slides up the other incline and gradually takes its own weight off
and bears up with the spring to ease the underfaller when finishing an inward run.
In lieu of the pivoted lever this apparatus may be applied to the ordinary "salmon-
head" lever 'or levers at present employed in mules.

We, JOHN ELLISON of 12 Elizabeth Street, Deane Road, Inventor, and
JOSEPH HALL of 5 Glynn Street, Teacher of Cotton Spinning at Manchester
Technical Schools, 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 and twiners for
spinning cotton, wool, worsted, silk, and other fibrous substances and has for its
object that of depressing and easing the underfaller to prevent snicks, snarls,

Fig. 3 a
of rod J,
A is the faller rod; B the underfaller rod, and C the mule carriage. On the
back side of the mule carriage C we secure the fixing D to which is pivoted the
lever E by the pin G. On the front end of the lever E is mounted the bowl or
roller H by means of the pin or centre F. The front end of the lever E is provided
with the hole or slot I through which passes and swivels the rod J hung from the
arm or lever K attached to the underfaller rod B. The upper end of the rod J is
screwed and provided with the nuts L between which and the lever E is placed the
spiral spring M. The rod J passes through the spiral spring M; the bottom end
of the latter being secured to the lever E by the set screw N. The lever E is
provided with the arm O and screw P; the latter operates against the fixing D
secured to the back side of the mule carriage C. The screw P is provided for the
purpose of taking the weight of the lever E off the underfaller when the latter rises
to a given point, and which may be so adjusted that it will take the weight off the
underfaller during the whole of the stretch when starting to spin cops. When the
mule commences spinning a fresh set of cops the underfaller rises higher than at
any other point, which allows the front end of the lever E to drop so low as to
cause the screw P to come in contact with the fixing D, thus taking the weight of
the lever E off and bearing by means of the spiral spring M, thus easing the yarn
throughout the stretch at bottom of cop only. As the cops build the underfaller
assumes a lower position consequently the lever E is raised and the screw P is
released from the fixing D as shown in Figs. 1 and 2, thus allowing the full weight
of the lever E to bear on underfaller. When the mule carriage C is completing an
outward run the bowl or roller H slides or runs up the incline R and gradually
takes the weight of the lever E off the underfaller and bears up by means of the
spiral spring M to ease the same during the operation of backing-off. When the
mule carriage C commences to make an inward run the spiral spring M gradually

page_text: allows the weight to be imparted as the bowl or roller H slides or runs down the
incline R when winding on thick part of cop. When the mule carriage C has
almost completed its inward run the bowl or roller H slides or runs up the incline S
and gradually takes off the weight of the lever E and bears up with the spring M
to ease the underfaller when finishing an inward run. The inclines R and S are
pivoted to the fixings T mounted or fixed on the mule room floor. If desired the
bottom end of rod J may be fitted with the bowl or roller V, as shown in Figs. 4
and 5, to allow the same to also operate on the incline S. In this case the latter
is increased in width to suit.
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 or lever fixed on the underfaller rod of a screwed
rod passing through a spiral spring, the upper end of the latter being secured to the
rod by nuts and to a lever at its lower end, the said lever being pivoted to mule
carriage and having a bowl or roller to slide or run up inclines so as to bear up by
means of the spiral spring to depress the underfaller at the end of the inward and
outward run of the mule carriage to take the strain off the yarn smoothly and
gradually, substantially as described.
2. In combination with the lever E of the arm O and screw P for the purpose of
taking the weight of the lever E off the underfaller when the latter rises to a given
point, also for taking the weight of the said lever off the underfaller during the
whole of the stretch when commencing to spin a fresh set of cops, substantially as
described.
3. The combinations, constructions, and arrangements of parts forming our
improved easing motion for mules and twiners, as hereinbefore described and as
illustrated in the annexed drawings.
