I, WILLIAM LEACH, of 54, Paxton Street, Accrington, Lancashire, Mechanic do
hereby declare the nature of my invention for "IMPROVEMENTS IN MACHINERY
FOR SPINNING AND DOUBLING COTTON AND OTHER FIBRES," to be as follows:-
My invention has reference to that class of machinery called "Mule throstles,"
but the improvements are equally applicable to other descriptions of machinery
employed in spinning and doubling fibres, either on the bare spindle or onto tubes
or bobbins placed thereon.
The first part of my invention consists in the employment of new and self-
acting means to be employed for lubricating the wharle which carries the eyelets
for winding the yarn upon the spindle or tube. As is well known these wharles
revolve at a very high speed, and therefore must be freely and constantly lubricated,
and this I accomplish in the following manner. A short flanged tube is attached to
the top rail, and upon this short tube I place the wharle which is driven by a band
from the usual tin cylinder. A cup is cast on the flange of the tube, and a hole is
bored (horizontally or at an inclination) near the bottom of the cup, in such
manner as to form a communication between the cup and the outside of the tube,
so that when tallow or other lubricant is placed into the said cup, it passes through
the horizontal hole to the tube, and freely and constantly lubricates the wharle.
In order to carry the lubricant through the hole, a wire is placed therein which
assists in feeding the lubricant forward, and making a constant communication
from the cup to the tube.
In order to stop the rotation of any of the wharles, which it is necessary to do
from time to time, I employ a piece of wire bent in the form of tongues, and which
are passed around a small collar formed underneath the wharle, which tongues the
workman closes, and the friction thereof on the wharle, immediately stops its
rotation.
The next part of my invention has reference to the means to be employed in
putting drag or tension on the spindles, which I accomplish by the employment of
a small clamp, placed on the end of a short lever, and caused to bear with more
or less friction upon the spindles, as, and when required. The lever carrying the

page_text: clamp is operated by means of mechanism described in a prior application for
Patent, made by me on the 9th of April, 1884 N° 6148; or the said lever may be
operated by any other well known mechanism.
My invention also relates to means to be employed in assisting to doff the cops
off the spindles after they are completed, and this I effect by the employment of
means which will lift each cop up its spindle for a short distance, say half an
inch, whereby they are loosened and can be more readily removed by the
attendant.
To accomplish this I place a collar upon each spindle at a point where the
bottom or nose of the cop is formed, and when the cops are fully formed these
collars are raised, and consequently the cops are also raised. The collars are lifted
by a rod and lever operated by the attendant or by a reciprocatory rod having
inclined wedges formed on it.

Improvements in Machinery for Spinning and Doubling Cotton 2
and other Fibres.
I, WILLIAM LEACH of 54 Paxton Street Accrington, Lancashire, Mechanic do
hereby declare the nature of my invention for "IMPROVEMENTS IN MACHINERY
FOR SPINNING AND DOUBLING COTTON, AND OTHER FIBRES," and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My invention has reference to that class of machinery called " Mule throstles "
but the improvements are equally applicable to other descriptions of machinery
employed in spinning and doubling fibres, either on the bare spindle, or onto
tubes or bobbins placed thereon.
The first part of my invention consists in the employment of new and self-
acting means to be employed for lubricating the wharle which carries the eyelets
for winding the yarn upon the spindle or tube. As is well known these wharles
revolve at a very high speed, and therefore must be freely and constantly
lubricated.
In order that this part of my invention may be more fully understood reference
is, made to the accompanying Sheet of drawings wherein Fig. 1 is plan view and

page_text: Fig. 2 sectional elevation of a wharle with my improved method of lubricating
same applied thereto. A is the stationary rail of the machine upon which is fixed
by nuts or other means a short flanged tube B carrying the ordinary wharle C
driven by band from the tin cylinder in the usual manner. On the flange of the
tube B is cast a cup D for receiving the lubricant, being fed therefrom by a small
piece of bent wire a to the vertical hole b from whence it passes along the hori-
zontal hole c to the outer side of the short tube B when the centrifugal action of
the wharle draws the said lubricant up and around the short tube, thereby freely
and constantly lubricating the wharle. A small groove or passage d is made in
the side of the tube opposite the opening c so as to encourage and receive the
lubricant.
Instead of feeding the lubricant from the cup to the short tube as described
and shewn in the drawings, the passage c may be in direct communication with
the cup, and may be at an inclination, the lubricant being assisted from the cup to
the passage by a piece of wire.
'
In order to prevent dirt from getting into the cup D, and also to prevent the
wharle from rising up in the tube B I employ a hinged plate P placed at a position
just above the wharle and oil cup, see Figs 4 5, and 6.
In order to stop the rotation of the wharle C which it is necessary to do from
time to time I employ a piece of wire E bent in the form of tongs, and which is
passed around the cup D and around the collar e formed underneath the wharle,
the two ends of the said tongs projecting beyond the rail as shewn in the
drawings.
When the workman desires to stop the rotation of the wharle, he does so by
pressing the two ends together, thereby drawing the tongs tightly around the
collar, the friction thereon immediately stopping the rotation of the wharle.
The next part of my invention has reference to means to he employed in putting
drag or tension on the spindles, which I accomplish by the employment of a small
metal clamp F (see Fig. 3) connected to a short lever G which is caused to bear upon
the spindle H as and when required. The lever G carrying the clamp F is operated
by means of a small bowl 31 attached to the reciprocatory bar 26 which in its
forward motion presses upon the tail 19 of the lever G thereby forcing the clamp
against the rotary spindle, but on the return motion of the bar 26 the pressure of
the crank is removed from the said spindle as more fully set forth and described in
prior Letters Patent granted to me N° 6148 A.D. 1884. The lever G may however
be operated by any other well known mechanism.
My invention also relates to means to be employed in assisting to "doff" the
cops off the spindles after they are completed, and this I effect by the employment
of means which will lift each cop up its spindle for a short distance, say half an
inch, whereby they are loosened and can be more readily removed by the
attendant.
This part of my invention is shewn at Figa 4 and 5 which are front elevations
of my improvements shewn in different positions. I is the bottom or lifting rail
carrying the bracket 10 which receives and supports the spindle H. On the
bracket 10 is cast or otherwise fastened thereto a loop f in which rides a recipro-
catory bar J caused to move backward and forward when required to do so by the
attendant, who operates the lever K (or screw) which is connected to the said bar J
by rod L. Each spindle is provided with a collar M the lower end of which is
provided with stud g and rests upon the bar J whilst the upper end of the said
collar is near the nose or bottom of the cop as shewn in the drawings. On the
underside of the bar J are inclined wedges h one to each spindle, or at such other
distances as may be required so that when the cops are full and ready for
removing, the lever K (or screw) is moved in the direction of the arrow,
inclined wedges riding up the loop fand raising the bar J thereby, consequently
the upper end of the collar M is forced against the cop bottom which is pushed
up the spindle bodily as seen in Fig. 5 after which the cop can be easily
removed.
the

page_text: In Fig 6 and 7 I have shewn another method of lifting the cops. In this case
I employ a horizontal shaft N carrying bosses n provided with fingers m.
At one
or both ends of the rod N is fixed a lever O which when oscillated causes the
said shaft to rock, in doing which the fingers m come into contact with studs ¿
projecting from the bottom of the collar M and the collar is lifted thereby and
the cop forced up the spindle. In order to prevent the collar M from turning
around by the rotation of the spindle I attach to the bottom of the said collars
prongs which fit into grooves formed at the top of the bracket 10.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is
Firstly. The combination of wharle tube B and oil cup D connected together by
a passage for the purpose of lubricating the wharle substantially in the manner
described and shewn in Figs 1 and 2.
Secondly. The use of the tongs E mounted and operated in the manner herein
shewn and described for stopping the rotation of the wharles.
Thirdly. In combination with lever GI claim the clamp F operated in the manner
herein set forth for putting drag or tension on the spindles.
Fourthly. The means substantially as herein shewn and described for pushing
ย
the cop forward upon its spindle to assist in doffing.
