Improvements in Spinning Mules.
I GEORGE Ross of 163 Ashton New Road, Manchester, in the County of
Lancaster, Manager in the employment of Messrs. John Hetherington & Sons
Limited of Pollard Street, in the same City, Machinists, do hereby declare the
nature of this invention to be as follows:-
In the ordinary working of the spinning mule at the commencement of the
building of the cops it is necessary or usual to take steps to add to the coherence
of the first layers of yarn for the reason that the movements which impart the
required coherence to the body of the cop are not in use at the early stage
of the building.
It is usual to stop the mule and to lower the faller whilst the cylinder is
revolved by acting by hand upon the rim band. The effect so obtained is very
irregular and my object is to obtain a more regular and beneficial effect. I fix a
ratchet or toothed or notched wheel upon the cylinder shaft and I provide a
lever whereby the said wheel can be turned to a limited extent at the required
times. The lever may be provided with a pawl to engage with the ratchet wheel
the pawl being disengaged self-actingly when the lever would be lowered or
moved back or may be jointed and formed to engage with the wheel when operated
upon or be otherwise arranged to be out of gear when not in use or the lever may
be removable. The movements of the lever would be limited by stops so that
the cylinder would be turned to an equal determined extent at each operation.
A boss of a cylinder shaft bearing might be used for a fulcrum for the lever
which might be shaped to sit upon such boss. In the case of the differential
motion constituting part of the stretching motion the planet wheels not being
balanced interfere to some extent with the regularity of motion of the parts. To
remedy this defect and to lessen the risk of breakage I duplicate the planet
wheels the additional wheels being mounted in line with the existing wheels
but on the other side of the main axis of revolution so that one set of wheels
balance the other set.

Improvements in Spinning Mules.
I GEORGE Ross of 163 Ashton New Road, Manchester, in the County of
Lancaster, Manager in the employment of Messrs. John Hetherington & Sons
Limited of Pollard Street, in the same City, Machinists, 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 and
accompanying drawings:
In the ordinary working of the spinning mule at the commencement of the
building of the cops it is necessary or usual to take steps to add to the coherence
of the first layers of yarn for the reason that the movements which impart the
required coherence to the body of the cop are not in use at the early stage of
the building.
It is usual to stop the mule and to lower the faller whilst the spindle driving
cylinder is revolved by acting by hand upon the rim band.

page_text: The effect so obtained is very irregular and my object is to obtain a more regular
and beneficial effect.
I fix a ratchet or toothed or notched wheel upon the cylinder shaft and I
provide a lever whereby the said wheel can be turned to a limited extent at the
required times. The lever may be provided with a pawl to engage with the
ratchet wheel the pawl being disengaged self-actingly when the lever would be
lowered or moved back or may be jointed and formed to engage with the
wheel when operated upon or be otherwise arranged to be out of gear when not
in use or the lever may be removable.
.
In the case of the differential motion constituting part of the stretching motion
the planet wheels not being balanced interfere to some extent with the regularity
of motion of the parts.
To remedy this defect and to lessen the risk of breakage I duplicate the planet
wheels the additional wheels being mounted in line with the existing wheels
but on the other side of the main axis of revolution so that one set of wheels
balances the other set.
My invention is illustrated by the accompanying drawings to which I will refer
in this place.
Fig. 1 of the said drawings is an inner end view of a mule carriage parts
not necessary. to the sufficient illustration of my invention being left out of the
drawings.
In the said fig. a is one of the shafts which carry the cylinders or tin rollers
which are mounted to revolve within the carriage b as is usual.
Upon this shaft I fix a ratchet wheel c this wheel also appearing in Fig. 2 which
shows the opposite side of the wheel which would be next to the cylinder end d in
Fig. 1. This ratchet wheel is turned at the required times by means of a hand
wheel e which carries a pawl fadapted to engage with the teeth of the ratchet
wheel. In the example one end of the said lever is shaped to sit upon the boss of
the bearing for the shaft a so that the said boss serves as a fulcrum and at the
same time the lever can be readily lifted off and removed and be replaced. When
the use of the lever is not required the lever rests upon the foot step board
as in Fig. 1 or upon a suitable support. When so resting the tail f¹ of the pawl
rests upon a stud / or upon any suitable part in such a manner as that the acting
nose of the pawl is kept clear of the ratchet wheel as shown in the drawings.
When the handle end of the lever is raised the pawl engages with the ratchet
wheel and on continuing to raise the lever the cylinder d is turned in the direction
indicated by the arrow. The limit of upward movement of the lever may be
determined by a fixed or adjustable stud or stop which does not appear in
the drawing so that the cylinder may be turned to an equal determined extent at
each operation.
When the use of the lever is no longer required for the set of cops in course of
formation the lever may remain in position or be lifted off and applied to another
mule as preferred.
The arrangements for keeping the pawl out of gear when the lever is not in
use may be varied and also a notched wheel and catch or trigger might be applied
in, place of the ratchet wheel and pawl shown or a smooth rimmed wheel might
be used and be turned by a dog or gripper upon the hand lever or forming part of
such lever.
The differential motion is illustrated by Figs. 3 and 4 Fig. 3 being an under-
side view and Fig. 4 an elevation of the motion.
k
In these figs. represents the bevel wheel through which the vertical shaft / is
driven. The differential gearing is indicated by dotted lines and circles in the
figs. being hidden by the shield or casing m. The wheel which is held during the
slow motion for stretching or jacking is at n the driven wheel which is fixed upon
the shaft being represented by o. Around these two wheels the two sets of
planet wheels p and revolve upon the studs ss during the stretching each set of
planet wheels consisting of two wheels differing in size as is usual. The action is

page_text: the same as in the ordinary apparatus the only difference being the addition of a
second set of planet wheels say for example the set r to act in concert with the
ordinary set p and to balance such ordinary set and at the same time to divide the
strain so as to lessen the risk of breakage.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. The ratchet wheel c fixed on the cylinder or tin roller shaft a of a mule and
the hand levere and pawl f for turning such ratchet wheel substantially as and
for the purpose set forth and indicated.
2. The hand lever e shaped to sit upon the boss of a bearing for the tin roller
shaft of a mule or otherwise suitably mounted and carrying a pawl catch or
dog to engage with and turn a wheel upon the said shaft at the times and for the
purpose set forth.
3. The differential motion for a mule such motion containing two sets of planet
wheels mounted upon opposite sides of the common centre of motion as and for
the purpose set forth and indicated with reference to Figs. 3 and 4 of the attached
drawings.
