We, JOHN MCQUEEN, of John Hetherington and Sons Limited, of Vulcan Works,
Pollard Street, Manchester, in the County of Lancaster, Machine Maker, and JAMES
SHARP, of the same address, Foreman of Mule Department, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to mules for spinning cotton and other waste and the object
of our invention is to combine the differential notion for driving the front roller
when spinning and the motion for turning the front roller for the delivery of yarn
when the carriage is running in so that both motions can be worked simultaneously
when desired.
In carrying out our invention we employ a clutch on the front roller driven from
the rim shaft but we fit the clutch on a feather key in a long boss on which is
secured a toothed wheel for driving the differential motion when spinning. We key
also upon the long boss a second toothed wheel which is connected by change wheels
to a wheel driven by a toothed wheel mounted upon the side shaft or back shaft; in
this manner the front roller can be turned for the delivery of yarn as the carriage
runs in. If it be desired to dispense with the latter motion the carrier wheel may
be removed.
By working both motions simultaneously the production of the mule can be
materially increased.

Improvements in Mules for Spinning Waste....
We, JOHN MCQUEEN, of John Hetherington and Sons Limited, of Vulcan Works,
Pollard Street, Manchester, in the County of Lancaster, Machine Maker, and JAMES
SHARP, of the same address, Foreman of 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:-

page_text: Our invention relates to mules for spinning cotton and other waste and the object
of our invention is to combine the motion for driving the front roller when spinning
and the motion for turning the front roller for the delivery of yarn when the carriage
is running in so that either motion can be worked as required.
In the accompanying Sheet of Drawings-
Figure 1 is a side elevation, Fig. 2 an end. elevation and Fig. 3 a plan showing an
arrangement according to our invention for combining the motion for driving the
front rollers while spinning is taking place with the delivery motion for turning the
front rollers while the carriage is running in.
Fig. 4 is a detail view, on a larger scale, of one of the parts..
In the drawings, a designates the front roller shaft b a spur wheel and half clutch
loose on the front roller shaft and driven as usual by gearing, not shown, from the
rim shaft, c is the other half clutch fitted to slide on a feather key in a sleeve d
which is loose on the front roller shaft, e is the spring arm connected to the sliding
half clutch c and operated as usual by connections from the ordinary change
lever; f, g, spur wheels fixed on the sleeve d.
The change gearing for giving motion to the front rollers whilst the carriage is
running out and spinning is taking place, is driven from the wheel g and consists of
the following train of gears, namely, a pinion / carried on a stud h¹ and driving a
spur wheel i on a stud i¹ on which is also fixed a change wheel j gearing into a spur
wheel fixed on a stud k¹ and driving a spur wheel fixed on the front roller shaft a
whereby the latter is driven when the half clutch c is in gear with the other half
clutch on the spur wheel b.
The yarn delivery motion by which the front rollers are driven during the inward
run of the carriage is transmitted from the side shaft m on which is fixed a bevel
pinion gearing into a bevel wheel o which is mounted loose on a stud p; also
mounted loose on the stud p is a wheel of which has internal ratchet teeth as well as
external teeth as shown in the detail view, Fig. 4. A pawl q is pivoted at q¹ to the
side of the bevel wheel o and is connected by means of a link q³ to one arm of a leather
lined gripping spring 7 mounted on the stud p. The external teeth of the wheel o¹
gear into a carrier which in turn gears with the spur wheel ƒ fixed on the loose
sleeve d.
When the clutch c is in gear and the front rollers are being driven from the rim
shaft the wheel f drives the wheel o¹ in the same direction as the pawl q² but at a
quicker speed the pawl being held out of gear with the internal ratchet teeth by the
spring q. When, however, the clutch c is out of gear and the side shaft becomes the
driver, the pawl q2 drives the wheel o¹ and through the carrier the wheel of and so
through the wheel g and the change gearing the front roller shaft a whereby the
front rollers are driven at a slow speed and deliver a few inches of yarn while the
carriage is running in.
Instead of driving the bevel wheel o from the side shaft it might be driven directly
from the back shaft if preferred.
By combining the two driving motions for the front rollers as above described we
are enabled to run the carriage constantly at its highest speed and to regulate the
amount of yarn delivered by the front rollers according to the count by changing the
wheel or other wheel or wheels for one of larger or smaller diameter as required.
our said
Having now particularly described and ascertained the nature of
invention, and in what manner the same is to be performed, we declare that what we
claim is :-
1. Combining the change gear driving for the front roller shaft from the rim shaft
during the outward run of the carriage with the yarn delivery motion from the side
shaft or back shaft during the inward run of the carriage whereby the carriage
can be run constantly at its quickest speed and the amount of yarn delivered can be
regulated by changing a wheel or wheels in the train of gearing.
2. The general arrangement and combination of the parts embodying our improve-
