Batley, in the County of York, Designer, and ERNEST FIRTH, of Whitelee, Batley
aforesaid, Woollen Spinner, do hereby declare the nature of this invention to be
as follows:
Our invention consists in building a cop upon the bare spindle, or upon a thin
tube upon the spindle such cop being intended to be used in a shuttle for weaving
purposes, our object being to dispense entirely with the use of a bobbin or spool
by which means the shuttle contains a very much larger quantity of weft than
could possibly be the case when the weft is wound upon a bobbin as is customary.
Our invention consists in building up a cop of solid thread on the spindle of a
self-acting mule in quite a new and novel manner, that is to say, we build up
the cop in a self-acting mule in the form of a cheese, now made in a winding
machine, and this is effected by cross winding.
In carrying out our invention we cause the faller and the faller leg to be
intermittently rising and falling when the carriage is running back during the
operation of winding-on. The faller is thus making the thread to be constantly
crossing and reerossing as the cop is being built up. This method of building
up a cop makes it firm and solid and when placed in a shuttle the weft is intended.
to be unwound, not from the outside of the cop, as is usual, but from the inside.
The mechanism we employ for building up the cop in a self-acting mule by
crossing the threads as above set forth may
be various, but according to one
method the foot of the faller leg may ride over a rail the upper surface of which is
undulating, that is, having concave and convex surfaces so that as the foot of
the faller leg rides over this undulating surface the faller is raised and lowered
for the purpose of crossing the thread upon the cop.
According to another method the foot of the faller leg may be connected to a
toothed wheel not upon the centre, but eccentric, therewith. The toothed wheel
in this case would ride over a toothed rack giving to the faller leg a constantly up
and down motion for the purpose of crossing the threads upon the cop; or other
means may be employed for giving an up and down motion to the faller such as
a crank or a box cam or other equivalent devices.

We, ARTHUR TAYLOR, of 78, Co-operative Buildings, Bradford Road West,
Batley, in the County of York, Designer, and ERNEST FIRTH, of Whitelee, Batley
aforesaid, Woollen Spinner, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
Our invention consists in building a cop upon the bare spindle, or upon a tube
upon the spindle, such cop being intended to be used in a shuttle for weaving
purposes, our object being to dispense entirely with the use of a bobbin or spool,
by which means the shuttle contains a very much larger quantity of weft than
could possibly be the case when the weft is wound upon a bobbin as is customary.
Our invention consists in building up a cop of solid thread on the spindle of a
self acting mule in quite a new and novel manner, that is to say, we build up
the cop in a self acting mule in the form of a cheese, as now made in a weft
winding machine, and this is effected by crosswinding.
In carrying out our invention we cause the faller and the faller leg to be
intermittently rising and falling when the carriage is running back during
the operation of winding-on. The faller is thus making the thread to be
constantly crossing and recrossing as the cop is being built up. This method
of building up a cop makes it firm and solid and when placed in a shuttle the
weft is intended to be unwound, not from the outside of the cop, as is usual, but
from the inside of said cop.
To the aforesaid purpose our invention consists of a new and improved method
and novel and peculiar arrangement, and construction of the several parts of
the mechanism all as hereinafter fully described.
In the accompanying drawings illustrating our invention, Fig. 1, is sectional
side elevation of so much of the outer end piece of the headstock of a self
acting mule and of the mule, carriage as is essential to shew the application
of our improvements, the mule, carriage being shewn about midway of its return
traverse from the extremity of the "draw" to the beam.
Referring to the drawings, letter b represents the mule carriage; c the tin
cylinder mounted on shaft c¹ journalled in bearings in said carriage; d, are the
spindles which are driven by bands from the tin cylinder e; e is the faller leg
connected at e¹ to the front faller f secured on the shaft f¹, to which are secured
arms (one only being shewn) carrying the front faller wire g¹ extend-
ing from end to end of the mule and being actuated by said faller
leg to guide the yarn upon the spindles during the return traverse of the
carriage from the extremity of the "draw" to the beam; his the counterfaller
shaft (the parts connected with which are omitted,) and i one of our improved
copping rails resting all along its length on longitudinal bars 11 and 12
"
The faller leg at the end of the outward traverse of the mule carriage bis raised
up until the foot thereof passes over and engages with the stud or roll on the
end of lever pivoted at 2, to a bracket at the rear of the mule carriage, said
lever being supported by pulley or bowl mounted on a stud j5 secured to the
free end of the lever ¹, which pulley jrests on and is adapted to ride over the
upper surface of the copping rail i.
When the carriage arrives at the beam, the ordinary fixed stop piece (not
shewn) acts on the faller leg e, and forces it off the stud j against which it rests
idly during the spinning of the yarn or outward traverse of the mule carriage,
the descent of the faller leg carrying the front faller wire g' over to the front
of the spindles d out of the way.

page_text: The arrangement and operation of the parts above described will be well
understood by those skilled in the art to which our invention refers.
In addition to the ordinary movement given to the front faller wire g¹ for
guiding the yarn to build up each successive chase from the base to the nose
of the cop and which is derived from lever j¹ and faller leg e from the copping
rail, our invention consists primarily in the methods of and mechanism for
crossing and recrossing the yarn as it is wound upon the cop to produce a cross-
wound cop, such as shewn at Fig. 7, these methods for crossing and recrossing
the yarn comprising the reciprocation of the faller wire in guiding the yarn to
the cop, whereby the yarn is rapidly guided up and down within the limits of the
movement of the front faller wire, causing it to be crossed and recrossed from
left to right and right to left, one turn of yarn being crossed at an opposing
angle and the turn of yarn wound on the cop as many times as may be desired.
The means for giving reciprocatory motion to the front faller wire g¹ at each
winding on of yarn comprises in one case a series of corrugations or opposing
inclined planes K, K', formed on the track of the copping rail. As the bowl
or pulley travels along the track of the copping rail it rides up and down over
said corrugations or opposing inclined surfaces K, K', as is illustrated in full
line and in dotted line in Fig. 1, and gives a reciprocatory motion to the pivotted
lever, which when the faller leg e is engaged on the stud j on said lever, receives
this up and down motion, and through faller f and arm g imparts a reciprocatory
motion to the front faller wire g', which causes the yarn to be constantly crossed
and recrossed in building up the cop, such crossing and recrossing of the turns
of yarn building up a firm compact cop which, can be wound upon the bare
spindle, or on tubes placed thereon, and used as weft in a loom without requiring
a bobbin or spool to hold it in the shuttle. When the cop is placed in the shuttle
and the loom weaving, the yarn is unwound from the inside of the cop, it being
drawn from within the base thereof, as indicated at 20, Fig. 7.
Fig. 2 is elevation of another method of imparting an up and down motion
to the faller leg e, and this is accomplished by means of a pinion 8 connected
eccentrically by a link 9 to a rocking box 3 fulcrummed at 4.
This pinion 8 gears
into a toothed rack and as the carriage of the mule runs in towards the head-
stock, the said pinion rides over the rack, and thus, through the link 9, gives
an upward and downward motion to the faller leg e.
Fig. 3 illustrates the ordinary method of supporting the faller leg e, in which
case, the bowl rides upon the upper plain surface of an ordinary rail ³, but
this only operates the faller wire for building a nose upon the cop in the
ordinary manner, and forms no part of our invention.

"
For convenience sake we combine three different forms of rails i, 1, 2, in one
long longitudinal bar or casting as shewn in plan Fig. 4, and in cross section
Fig. 5. In making use of our combined copping rail, we fix on the floor two
parallel bars or supports 11 and 12, see Fig. 5 and in the space between the said
bars one leg or arm i, 2, 3, of our copping rail is introduced or placed between
bars 11 and 12 for being supported. Although there are only three copping rails
on the bar, a fourth 23 is used as a support to the other three rails, and forms a
stiffener therefor. By means of our combined copping rail which is interchange-
able, yarns of different classes can be spun into cops on the crosswinding system,
and by turning the rail over as shewn in Fig. 5 from one rail to the other, yarns
can be spun into cops in different methods, as well as in the ordinary and well
known manner.
To increase or decrease the number of crossings of yarn in building up the cop
the rail may have a larger or smaller number of depressions and the pinion
wheel 8 in Fig. 2 may have more or less teeth.
In order to either lengthen or shorten the nose of the cop as required, during
the process of building, we form a slot in the end of the faller f, in which slot
is a screw having on its outer end a ratchet wheel m and a lever n which
carries a pawl n¹ (see Fig. 6). The screw ¹ works through a block 2 (see Fig. 1)

page_text: and as said screw is rotated in one direction the sliding block 78 is caused to
travel along the screw from the inner end of the slot to the outer end thereof
and thereby gradually reduce the leverage and motion of the faller f as the
building up of the cop proceeds.
The screw is actuated when the faller lege is forced off the stud j on the mule
carriage arriving at the beam, by means of a fixed stop piece o (see Fig. 6) with
which the lever n engages as the faller leg descends and being thus turned on
its centre by said stop piece the pawl n is caused to turn the ratchet wheel m
a distance equal to one or more teeth as required, thereby giving the requisite
rotation to the screw to advance the sliding block the proper distance further
from the centre or fulcrum of the faller f.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is: -
1. In a self acting mule, the use therein of an undulating copping rail for
crossing the yarn, in combination with an adjusting screw for lengthening
or shortening the nose of the cop, substantially as described herein and shewn
in Figs. 1 and 6.
2. In a self acting mule the use therein of a rack and pinion, for building up
a cop on the crosswinding principle as shewn in Fig. 2 and herein described.
3. In a self acting mule the use therein of a combined copping rail such as
shewn in Figs. 4 and 5.
