PROVISIONAL SPECIFICATION.
Improvements in Self Acting Mules and Twiners.
We, ASA LEES AND COMPANY LIMITED, of Soho Iron Works, Oldham, in the
County of Lancaster, Machinists, and JOHN CLEGG, of the same address, Manager
of Mule Department, do hereby declare the nature of this invention to be as
follows:
Our invention relates to improvements in self acting mules and twiners and
the chief object of our improvements is to maintain the speed of the spindles as
high as possible during the backing off operation.
It is now customary to drive the backing off cone wheel or friction wheel
mounted on the rim shaft by a pinion on the horizontal taking in shaft gearing
into the teeth on the periphery of the backing off cone wheel.
According to our invention we disconnect the backing off cone wheel from the
taking in shaft and instead we gear the teeth on the backing off cone wheel into
a pinion mounted upon an independent stud or short shaft carried in a stationary
bracket; this pinion receives motion by means of a pulley also mounted on the
stud or shaft and driven from a pulley on the countershaft which drives the rim
pulley. By this means the backing off cone wheel being now quite independent
of the taking-in shaft can be driven at any speed desired from the countershaft.
For example, when the rim band pulley for driving the spindles is changed say
to a rim pulley of smaller diameter we can readily increase the speed of the
backing off cone wheel by changing the pulley on the countershaft for one of
larger diameter or by reducing the diameter of the pulley upon the stud or short
shaft whichever may be more convenient.
When a rope or round band is employed between the pulleys we propose to
employ a tightening device for the band.

Improvements in Self Acting Mules and Twiners.
We, ASA LEES AND COMPANY LIMITED, of Soho Iron Works, Oldham, in the
County of Lancaster, Machinists, and JOHN CLEGG, of the same address, Manager,
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:-
Our invention relates to improvements in self acting mules and twiners and

page_text: the chief object of our improvements is to maintain the speed of the spindles as
high as possible during the backing off operation.
It is now customary to drive the backing off cone wheel or friction wheel
mounted on the rim shaft by a pinion on the horizontal taking in shaft gearing
into the teeth on the periphery of the backing off cone wheel.
In the accompanying drawing-
Figure 1 is an end elevation and Figure a side elevation of part of a self
acting mule to which our improvements are applied.
In these views,-a designates the countershaft, a¹, a³, the pair of pulleys by
which it is driven, a³ a grooved pulley for driving the taking in shaft b as usual,
a broad pulley or drum for driving by a belt & the pair of pulleys e on the rim
shaft on which is mounted as usual the backing off cone wheel g.
According to our invention we disconnect the backing off cone wheel y from the
taking in shaft 6 and instead we gear the teeth on the backing off cone wheel I
into a pinion h fixed on a short shaft carried in a stationary bracket j. On
the shaft we fix a grooved pulley k which is driven by a rope m from a grooved
pulley n fixed on the countershaft a; or the pinion h might be otherwise suitably,
mounted and driven in any convenient manner.
By this means the backing off cone wheel g, being now quite independent of the
taking in shaft b, can be driven at any speed desired from the countershaft a.
For example, when the rim band pulley o for driving the spindles is changed
say to a rim pulley of smaller diameter, we can readily increase the speed of the
backing off cone wheel g by changing the rope m from one groove to another of
the pulleys k, n. In like manner when we drive the short shaft by a belt and plain
pulleys we effect the desired change of speed by changing the pulley on the
countershaft for one of larger diameter or by reducing the diameter of the pulley
upon the shaft i whichever may be more convenient.
When a rope or round band is employed between the pulleys we propose to
employ a tightening device for regulating the tension of the same.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is:-
-
In a self acting mule or twiner-
1. Disconnecting the backing off cone wheel from the taking in shaft and in-
stead driving the same by a pinion mounted on an independent shaft or stud
and driven preferably from the countershaft from which the rim shaft is driven.
2. The combination with the backing off cone wheel g, of the pinion h mounted
on the independent shaft i (or on a stud) and driven by the means shown or
equivalent means substantially as and for the purposes herein set forth.
