Improvements in Spinning Mules.
I, JOSEPH STEVENS of 34 St. James Street, Peartree Road, Derby, in the County
of Derbyshire, Machinist, do hereby declare the nature of this invention to be as
follows:
This invention relates to machinery for spinning wool, and other material such as
cotton, flax and the like, into yarn by means of rollers, generally known as
mule spinning machinery, and has for object to provide a new or improved appliance
or attachment to such mules, which, being simple, durable and inexpensive in
construction, is calculated to materially reduce or partially prevent the hitherto
unavoidable waste of material, without interfering with or complicating the
manipulation and adjustment of the speed regulating and other mechanisms forming
part of the said mule spinning machinery now in general use. My new or improved.
waste reducing appliance will be found especially serviceable with that class of mule
machinery which is used for spinning worsted yarns.
The said appliance or attachment essentially consists of a steel bar brought into
close juxtaposition with that part of the mule known as the fluted roller, so that by .
the rotation of the latter a volume of air is being driven into and through the narrow
interstice between the fluted roller and the said steel bar, carrying along small
shreds and particles, which have been separated from the material by the action of
the under cleaner, and would otherwise fall to the ground as waste, towards the
thread passing over the fluted roller on its way to the spindle, tending to re incoporate
said small shreds and particles with the thread.
In carrying out my invention in practice, I provide conveniently shaped and
sectional bracket attachments made of brass or other suitable material, one of which.
I secure by means of screws or in other efficient fashion to the bearing parts of each
of the bracket arms supporting the fluted roller. Said bracket attachments have
vertically extending longitudinal grooves or cuts of convenient depth and width
provided in their upper surfaces intended to receive the correspondingly flattened
shoulder ends of a steel bar of any suitable semi-circular cross section; the said
steel bar runs parallel to the fluted roller from bracket to bracket with its flat
surface turned towards the fluted roller in such manner, as to cause the upper edge.
of the flat surface to lie close to, without however touching the fluted roller which
revolves with the under cleaner and drawing roller of the machine.
I generally find it expedient to provide in the flat surface of aforesaid steel
bar a suitably determined recess extending along the whole length of the bar and in
width about three quarters of the width of the bar from its lowermost edge in an
upward direction. This recess serves to receive and hold a narrow strip or band of
cloth or other suitable material corresponding to the dimensions of the recess.
Small particles of the material under treatment will adhere to the said cloth strip
and can be brushed off with facility when the apparatus is being cleaned. The
aforesaid recess may however be dispensed with and the flat surface of the bar be left
plain and smooth.

page_text: In some cases it may be found advisable or expedient according to the nature of the
material under treatment to magnetise the herein before described steel bars.
Dated this 6th day of July 1897.

I JOSEPH STEVENS of 34 St. James Street, Pear-Tree Road, Derby in the County of
Derbyshire, Machinist, 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.
This invention relates to machinery for spinning wool and other material such as
cotton, flax, and the like into yarn, by means of rollers, generally known as mule
spinning machinery and has for object to provide a new or improved attachment to
such mules, which, being simple, durable and inexpensive in construction is
calculated to materially reduce or partially prevent the hitherto unavoidable waste of
material, without interfering with or complicating the manipulation and adjustment of
the speed regulating and other mechanisms forming part of the said mule spinning
machinery now in general use.
My new or improved waste reducing appliance will be found especially servicable
with that class of mule machinery which is used for spinning worsted yarns.
The said attachment consists, essentially, of a steel bar brought into close
juxtaposition with that part of the mule known as the fluted roller-so that by the
rotation of the latter a volume of air is driven into and through the narrow interstices
between the fluted roller and the said steel bar carrying along small shreads and
particles which have been separated from the material, by the action of the
undercleaner (which would otherwise fall to the ground as waste) towards the thread
passing over the fluted roller on its way to the spindle, tending to incorporate the
small shreads and particles with the thread.
In order to render my invention more readily to be understood and carried out in
practice I have hereunto attached two sheets of drawings upon which :-
Fig. 1, Sheet 1, represents a side elevation of a mule spinning apparatus, showing
the steel-bar attachment in position.
Fig. 1A, Sheet 1, is a vertical cross section through fluted roller and steel bar,
illustrating their proper relative position, and
Fig. 2, Sheet 2, is a front elevation of a mule spinning apparatus giving a front
view of the aforesaid steel-bar attachment.
Throughout, the figures of the drawings like letters of reference denote like or
corresponding parts.
In carrying my invention into practice I provide suitably shaped and sectioned
bracket attachments d made of brass or other convenient material, one of which I
secure by means of screws or in other efficient fashion to the bearing portions of
each of the bracket arms a', supporting the fluted roller a.
Said bracket attachments d, have vertically extended longitudinal grooves or cuts
of convenient depth and width provided in their upper surfaces, intended to receive
the correspondingly flattened shoulder-ends of a steel bar e, of any suitable
semicircular cross section; said steel bar e, extends parallel to the fluted roller a,
from bearing to bearing with its flat surface turned towards the fluted roller in such
manner as to cause the upper edge of the flat surface to lie close to without however

page_text: touching the fluted roller a revolving with the under cleaner c and the drawing roller b,
of the machine.
I find that sometimes it will be suitable or expedient to provide the flat surface of
aforesaid steel-bar e, with a suitably determined recess e¹ (Fig. 1^) extending along the
whole length of the bar e, and in width about three quarters of the width of the bar
from its lowerinost edge in an upward direction. This recess e¹, serves to receive and
hold a narrow strip or band of cloth or other suitable material corresponding to the
dimensions of the recess. Small particles will adhere to said cloth strip and can
easily be brushed off when the apparatus is being cleaned.
The aforesaid recess may however be dispensed with and the flat surface of the bar
left plain and smooth.
In some cases it may be found desirable or expedient, according to the nature of
the material under treatment, to magnetise the said steel bar.
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 :-
The new
or improved waste reducing appliance to spinning mule machinery
essentially consisting of a bar.e, held in bracket pieces d, in determined juxtaposition
to fluted roller a, substantially as and for the purpose set forth and illustrated in
the accompanying drawings
