I, PAUL WALLACE, of Armitage Bridge in the County of York Overlooker, do
hereby declare the nature of my invention for IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR ROVING SPINNING OR DOUBLING COTTON 'AND OTHER" FIBROUS
SUBSTANCES to be as follows:―
L
These Improvements relate to Machinery or apparatus employed in roving
spinning or doubling Cotton and other fibrous substances and has for its object to
enable bobbins or cops of various sizes and of either hard or soft yarn to be
produced by the same apparatus.
F
In carrying out my Invention I employ a spindle upon which is secured' a
flanged cup one or more spaces or openings being left or formed between the
flanged cup and the spindle for the passage of the hereinafter described slotted
bobbin.
Below the flanged cup and cast or forged in one piece therewith is a "wharve"
or small grooved pulley by means of which the cup and spindle are driven in the
usual manner.
The cop or bobbin is wound upon a sleeve or tube made to fit the spindle a
and
having portions of its circumference cut away so that it may pass between the
flanged cup and the spindle for say two thirds of its length, the remaining third of
the tube being left intact.
This slotted tube may be lifted and lowered vertically on the spindle as may be
required in forming the cop or bobbin by any ordinary or convenient building
motion regard being had to the fact that the cone of the cop will require to be in
the opposite position to that in which it is produced in ordinary ring spinning.

Upon the flange of the cup there is mounted a yarn guide or traveller through
which the yarn passes as it is wound upon the cop or bobbin. By means of this
traveller the amount of twist put into the yarn may be varied by accelerating or
retarding its motion with the cup. This is accomplished by means of a brush
rotating in contact with the flange of the cup and therefore touching the traveller
once in every revolution. If the brush revolves at a slower rate than the flanged
cup the traveller will be retarded, if on the contrary the brush revolves at a higher
speed than the cup the traveller will receive an impulse at each revolution and
have its motion accelerated.
The brush has a variable speed imparted to it by driving it from a band running
upon conical pulleys, the position of the band upon the pulleys being governed by
a cane or other appliance as is well understood.

COMPLETE SPECIFICATION.
I, PAUL WALLACE of Armitage Bridge Yorkshire Overlooker, do hereby declare
the nature of my invention for. IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR ROVING, SPINNING OR DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
These. Improvements relate to Machinery or apparatus employed in roving,
spinning or doubling Cotton, Wool and other fibrous substances and have for their
object to enable bobbins or cops of various sizes and of either hard or soft yarn to
be produced by the same apparatus.
And in order that this my Invention may be more readily understood and
carried into practical effect I have hereunto appended a sheet of Drawings marked
with letters of reference similar letters denoting similar parts.
Fig 1'shows a front view, Fig 2 a plan Fig 3 a vertical section and Fig 4'a
horizontal section of my Improvements.
In carrying out my Invention I employ a spindle A upon which is secured a
flanged cup B'one or more spaces or openings C being left or formed between the
flanged cup and the "spindle for the passage of the hereinafter described slotted
bobbin or sleeve D.

Below the flanged cup and cast or forged therewith or otherwise secured thereto
is a "wharve" or small grooved pulley E by means of which the cup and spindle
are driven in the usual manner. The part between the flanged cup and the wharve
is formed to a bearing F in the top or collar rail G. The front part of the top
rail may be removable along the line H H to facilitate the insertion and with-
drawal of the spindle and its attachments. For the same purpose the hole' I 'in' the
lifting rail K in which the spindle bearing L' rests should be made oblong as shown
in Fig 3 and in dotted lines in Fig 4.

"The cop or bobbin is wound upon the tube or sleeve D., This sleeve is so con-
structed that it may slide freely upon the spindle notwithstanding the attachment
or connection between the spindle and the external cup and wharve. For this
purpose the sleeve may be slotted from the bottom to near the upper end as shown
in dotted lines in Fig 3 and in section in Fig 4 in which case the connection may
be made by means of a wing welded or otherwise sécured to the spindle and
similarly secured to the cup and wharve. Such a wing is indicated at M in dotted
lines in the right spindle of Fig 1, in Fig 3 and in section in Fig 4. The sleeve D
rests upon the lifting rail K and it should be of such a length? as to permit the
full length of the cop or bobbin to be wound thereon before the lifting rail reaches
the full extent of its upward motion. The yarn may be wound directly upon the
sleeve D when it will be a substitute for a bobbin or a pin or pirn may be inserted
"

page_text: into the sleeve when the cop may be 'transferred from one to the other, 'but it will.
generally be more convenient to spin upon a thin slotted paper or metal tube
similar to the sleeve D'and fitting upon it.
Any ordinary or convenient motion may be employed for actuating the lifting
rail K by the pokers S regard being always had to the fact that the cone of the cop
will require to be in the opposite direction' to that occupied by it in the ordinary
methods, of continuous spinning.
Upon the flange of the cup there is mounted a yarn guide or traveller N through
which the yarn passes as it is being wound upon the sleeve or tube. By accelerating
or retarding the motion of the traveller with the revolving cup the amount of drag
or tension put upon the yarn may be varied at will. This is accomplished by
means of a horizontal brush O rotating in contact with the flange of the cup and
therefore touching the traveller once in every revolution. If the brush revolves at
a slower rate than the cup the motion of the traveller will be retarded, if on the
contrary the brush revolves at a higher speed than the cup the traveller will
receive an impulse at every revolution and its motion will be accelerated. The
spindle upon which the brush revolves may be secured by a nut P in an oblong
hole in the collar rail so that the amount of pressure or contact between the brush
and the cup flange may be varied by altering the position of the brush spindle.
One brush only is required for two cups as shown in Figs 1 and 2 and each brush
is provided with a wharve R Fig 1. The spindles and brushes may be driven by
means of bands passing round their respective wharves E and R and the tin
cylinder or its equivalent but I prefer for the purpose of varying the speed of the
brushes to drive the latter from a separate cylinder or pulleys the speed of which
may be governed at will relatively to the speed of the tin cylinder. The separato
cylinder or pulleys may be driven by a pair of conical pulleys connected by a belt
or band one of which is driven from the tin cylinder or suitable pulley while the
other drives the separate cylinder or pulleys from which motion is imparted to the
brushes. The speed of the brushes may then be varied by shifting the position of
the band upon the conical pulleys. This mode of securing variations of speed is
commonly employed for other purposes and is well understood.
In some cases the brush may remain stationary when the yarn will pull the
traveller through the brush contact producing thus sufficient retardation of the
traveller to effect the winding.
I desire it to be understood that I do not limit myself to the precise details
herein before set forth and described as these may be varied without departing from
my Invention. For example the wharve E may be mounted upon some portion of
the spindle instead of being secured to the cup-the cup may be secured to the
spindle by two or more wings a forked or other suitably shaped sleeve may be
used so that it may pass and be driven by the wings, or the upper part of the
sleeves may be dispensed with when spinning upon bobbins the bobbins being then
rotated by pins or projections from the lower part of the sleeves or by equivalent
means.
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
(1) The use of the flanged cup substantially as and for the purpose hereinbefore
described and set forth.
(2) The use of the revolving brush substantially as and for the purpose herein-
before described and set forth.
(3) The use of the slotted or equivalent sleeve in combination with the flanged
cup and spindle substantially as herein before described and set forth.
(4) The use of an opening or passage or of openings or passages between the
spindle and cup substantially as and for the purpose herein before described and set
forth.

page_text: (5) In combination with the flanged cup the use of the traveller substantially, as
herein before, set forth and described.
(6) The use of the flanged cup and traveller in combination with the horizontal
brush substantially as hereinbefore set forth and described.
