page_text: I, JOSEPH MOORHOUSE, of 200, Belgrave Road, Oldham, Mill Manager, do hereby
declare the nature of my said invention to be as follows:-
This invention relates to and consists of improvements in the driving of self-
acting mules and twiners.
According to my invention 1 employ a driving pulley on the counter-shaft
and a driving-pulley on the rim shaft, plain or grooved, around which I pass
a belt or belts, or ropes. Upon the counter-shaft I also arrange two other
pulleys, one of which is connected to, or forms part of the driving pulley afore-
said, whilst the other is separate. All three pulleys are loose upon the counter-
shaft. Between these last named pulleys I arrange another or intermediate pulley,
or rim, which is keyed to the counter-shaft. On this shaft is also keyed the
usual taking-in" pulley.
..
Around the pulley connected as aforesaid with the driving pulley is a driving
belt, and with such belt in motion and spinning takes place the belt is by pre-
ference partly on the said driving pulley and partly on the intermediate pulley.
When the changes take place the said belt is moved across the intermediate pulley
on to the loose pulley, but with a portion of such belt remaining on the inter-
mediate pulley. When the mule requires to stop, the belt is moved completely
on to loose pulley. For restarting the belt is moved back again across the inter-
mediate pulley on to the driving pulley.
As a modification I may mount the intermediate, loose and taking-in pulleys.
on a sleeve or hollow shaft, and make the driving pulleys either fast or loose on
the shaft.
Whilst prefering the pulley connected with the taking-in pulley to be between
the other pulleys, I may arrange it otherwise, with the traverse of the belt to.
suit. I may also vary the disposition of the parts to suit the space available, or
contingent requirements.
A further feature of my invention consists of one or more backing-off fric-
tion cones on the rim shaft supplementary to the ordinary backing-off friction
cones, and all engaging and disengaging simultaneously, or otherwise, as
required.

statement:-
-
This invention relates to and consists of improvements in the driving of self-
acting mules and twiners.
According to my invention I employ a belt or rope driving pulley on the
counter-shaft, and a corresponding or similar pulley on the rim shait around
which pass a belt or set of belts or ropes. Upon the counter-shaft I also
employ two other pulleys, one of which is connected to, or forms part of the
pulley aforesaid on the counter-shaff, and both of which are loose upon the said
shaft. Between these last named pulleys employ another or intermediate
pulley which is keyed to the counter-shaft. Upon this shaft is also keyed the
usual taking-in" pulleys.
"
Around the pulley connected as aforesaid with the driving pulley is a driving
belt, and with such belt in motion and spinning taking place the belt is also
partly on the intermediate pulley. When the changes take place the said belt
is entirely removed from off the driving pulley and is partly on the intermediate
pulley and partly on the loose pulley. When the mule requires to stop the belt
is moved completely on to the loose pulley.
For restarting the belt is moved back again across the intermediate pulley on
to the driving pulley.
As a modification I may mount the intermediate, loose and taking-in pulleys
on a sleeve or hollow shaft, and make the driving and band pulleys either fast
or loose on the shaft.
To make my invention clear I have hereunto annexed a sheet of drawings in
which Fig. I represents a side view of a mule headstock and frame with my
invention applied thereto.
Fig. 2 represents a side view of the several pulleys and the belt and bands
used therewith.
Fig. 3 represents a longitudinal section through the counter-shaft pulleys.
Fig. 4 represents a similar. section of a modification.
Figs. 5 and 6 represent certain details in plan and elevation.
According to my invention I apply to the rim shaft (A) a, by preference belt
pulley (B), and to the counter-shaft (C) a loose belt pulley (D). Around these
two pulleys I pass a belt (D). Upon the counter-shaft I also mount two further
pulleys (1) and (F), which are also loose upon the shaft, and the pulley (E) is
connected to, or is formed in one piece with the pulley (D).
Between the two pulleys (E) and (F) I mount a further and narrower pulley (G).
This latter is fast upon the shaft (C) upon which also is keyed the usual "taking-
in pulley (H). (1) is a driving. belt, which, when the mule is at rest, lies around
the loose pulley (F).
"
When the mule is started and the carriage is making its outward run for spin-
ning the belt. (I) is, by preference, partly on the pulley (E) and partly on the
pulley (G) as shewn in Fig. 3, thereby imparting motion to such pulleys and
driving the mule through pulleys (1) and belt (*) and keeping the taking-in
pulley constantly in motion ready to take immediate action when the changes
take place.
When backing-off is timed to take place the belt (1) is moved off the pulley (E)
to the position shewn in Fig. 1, .e. partly on the intermediate pulley (G) and
partly on the loose pulley (F), and in such position drives the taking-in band (J)
via pulley (G), shaft (C) and pulley (H). When the operation of backing-off is
completed and the carriage has made its inward run the bolt (I) is moved back
again to the position shewn in Fig. 3.
In Fig. 4 'I shew a modification of the counter-shaft pulleys. The pulleys (E)
and (D) are separate and both keyed to the shafts. (C) and in this modification
the pulley (D) is shewn grooved and adapted for rope driving as it may also be
in the previous modification.
The intermediate pulley (G) is mounted fast upon a sleeve (K) upon which is also

page_text: mounted the loose pulley (F) and the taking-in pulley (H). The driving of the
mule for spinning takes place through pulley (E), shaft (C), and pulley (D), and
when the changes take place the motion is imparted through pulley (G), sleeve (K),
and pulley (H).
The chief advantages of my invention is that there is no shifting of the belt (D³)
for backing-off, etc., thus greatly saving the life of such belt, enabling me to
dispense with the usual loose pulley on the rim shaft, and thereby effect a great
economy of room about the headstock. I am also enabled to use either rope or
belt driving.
The means I employ for moving the belt (1) may vary. In Fig. 1 I shew a
bell-crank lever (L) fulcrumed on a bracket (M) and with one end connected to
the starting rod (N) and the other end to the rod (O) which in turn is connected
to one arm of a further bell-crank lever (P) the fulcrum of which is supported
by a bracket depending from the ceiling or other over-head support. The other
arm of this lever engages with a pin (Q) on a strap fork bar (R) carried in exten-
sions (S) of the shaft bearing brackets (T).
Under the movements of the starting rod (N) the said strap fork bar is moved
to-and-fro, and the belt (I) moved as aforesaid. To allow of the movements of the
strap fork bar being automatic I connect the lever (L) with a lever (U) mount- upon
and operated by the usual strap guider shaft by means of a spring (V) and rod (W).
This latter has a slot at (X) so that when the starting rod (N) is pulled forward
to stop the mule it allows of the movement of the rod (N) whilst the spring (V)
holds it against the stud (Y) in working the strap fork bar.
To allow the starting rod (N) to be at rest after starting the mule I provide
it with a slot (Z) sufficiently long to allow of the swing of the arm (L) at each
of the changes. In lieu of a single belt (1³) I may employ two narrower belts.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed 1 declare that what
I claim is:-
1: In means for operating self-acting mules and twiners, an arrangement of-
pulleys, such as herein described, and a driving strap and guider controlled and
operated in the manner and for the purposes substantially as herein set forth.
2:-In means for operating self-acting mules and twiners, the use, in com-
bination, of a counter-shaft, a set of three loose pulleys and two fast pulleys on
such shaft, two of the loose pulleys being connected to each other, one of the
fast pulleys being a "taking-in" pulley and the other fast pulley lying alongside
and between two of the loose pulleys, a fast pulley on the rim shaft, a belt (or
band) passing around said pulley, and around one of the connected loose pulleys
on the counter-shaft, a driving strap for transmitting motion to the pulleys on
the counter-shaft, a strap guider for traversing the driving strap, and means for
operating such guider, substantially as herein set forth and illustrated on the
accompanying drawings.
3: In means for operating self-acting mules and twiners, the use, in com-
bination of a counter-shaft, a loose sleeve on such shaft, two pulleys keyed to
such sleeve, a loose pulley on said sleeve, two further pulleys on the counter-
shaft (fast, or joined and loose), a driving strap for transmitting motion thereto,
a fast pulley on the rim shaft, a band (or rope) passing around such pulley and
one of the pulleys on the counter-shaft, a strap guider for traversing the driving
strap, and means for operating the strap guider substantially as herein set forth
and illustrated on the accompanying drawings.
