Improvements in Machinery or Apparatus for Twisting Cords,
Driving Bands, or the like.
I, WILLIAM H. NAYLOR, of 483 North Fifth Street, Philadelphia Pa. United
States of America, Manufacturer, 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 :-
My invention relates to machines or apparatus for twisting cords or driving
bands which are intended for use more especially in connection with spinning
machines.
The main object of my said invention is to provide an improved machine or
apparatus by means of which the twisting of the said bands can be completed
without the necessity of transferring them to a second machine.
In the accompanying drawings I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a plan.
Figure 2 is a side elevation, and
Figure 3 is a vertical longitudinal section, showing my improved band twisting
machine.
Figure 4 is an enlarged view of a portion of Figure 2.
Figure 5 is a section on the line a, Figure 4, and
Figures 6 to 11 are different views showing details of construction drawn to
the same scale as Figures 4 and 5.
Figures 12 to 17 are diagrams illustrating the process of twisting the band..
A is the frame or bed of the machine which consists of two longitudinal portions
supported at each end by suitable standards A' and somewhat resembling the bed
of a lathe. B is a fast and B. a loose pulley supported upon a driving shaft or
arbor which latter is supported in suitable bearings (1 in brackets A² either
formed in one with or firmly secured to one of the end standards A'. D is the yarn
or other material to be twisted.
:
a is a main or longitudinal shaft or arbor running the full length of the fraine A
and supported in suitable bearings b in the standards or brackets A¹. The main or
longitudinal shaft or arbor a is geared to the driving-shaft C by means of bevel or
mitre wheels c, d the former of which is secured upon the said shaft a and the latter
upon a sleeve e carried upon the shaft or arbor C by means of a set screw or in any
other suitable manner. f is a key-way provided in the shaft or arbor C. in which is
adapted to work a corresponding key or projection provided on the said sleeve e so
that the latter can slide freely upon the said shaft or arbor C in a lateral direction
and will at the same time rotate therewith. The sleeve e can be moved laterally
upon the shaft or arbor C by means of a hand lever 9 pivoted at g₁ to a bracket h
secured to one of the standards A' and provided with a fork g (Figures 1 and 3) the
i is a second bevel or
prongs of which rest in an annular groove e¹ in the sleeve e.
mitre wheel fixed upon the said sleeve e by means of a set screw or otherwise and
having firmly secured thereto or formed in one therewith a worm . By moving the
lever g
the bevel or mitre wheel d can be thrown out of gear with the bevel or mitre
wheel c and the bevel or mitre wheel i thrown into gear therewith thus reversing the
movement of the main or longitudinal shaft or arbor a. The worm i¹ will at the same
time be thrown into gear with a worm wheel j supported on a spindle j', for the
purpose hereinafter described. k, k are spindles supported in suitable bearings in a
bracket attached to one of the standards A¹ and having at their outer ends hooks k!
over which the strands of the band to be twisted are placed. The said spindles
are provided with toothed pinions m gearing with a toothed wheel n secured upon

page_text: the main or longitudinal shaft or arbor a so that when the said shaft is revolved, the
said hooked spindles will revolve also. o is a travelling carriage adapted to slide or
move freely on the bed A.
Supported in suitable bearings o¹ on the travelling carriage o is a shaft or spindle p
having at its outer end a hook p¹ on which is intended to be strung the middle portion
of the yarn to be twisted. g is a pinion firmly secured upon the shaft or spindle p.
The pinion gears with a toothed wheel which is normally free to rotate upon the
main or longitudinal shaft or arbor a. s is a sleeve also supported upon the main
or, longitudinal shaft or arbor a. The sleeves is connected to the toothed wheel r
by means of a forked link s¹ which engages in a circumferential groover provided
in the boss 2 of the said toothed wheel r. The said sleeve s is connected moreover
to the travelling carriage o by means of a link or connecting rod o² (Figure 3).
The sleeves and the toothed wheel r move with the travelling carriage o the said
toothed wheel r not being rotated by the main or longitudinal shaft or arbor a until
a friction face ³ thereon comes in contact with a friction disc t. The friction disc t
is arranged to move laterally upon the said main or longitudinal shaft or arbor a so
as to have an independent movement along the said shaft.
For this purpose I
provide a key-way a¹ in the main or longitudinal shaft or arbor a and a corresponding
key feather or stud in the boss t¹ of the said friction disc t adapted to move freely
therein. u is a sleeve at the back of the disc t provided with arms or projections u¹
adapted to slide freely on suitable surfaces or guides provided on the bed-plate A.
v, v are weights, having wheels or pulleys v¹ round which are passed cords w one
extremity of each of which is connected at w¹ to the travelling carriage o and the other
extremity to the arms or projections u¹ on the sleeve u, so that as soon as the band
being twisted is removed the said sleeve u, friction disc t and carriage o will be
brought back to their normal positions by the action of the said weights v. v², v³ are
idle wheels or pulleys for guiding the said cords w.
a is a lever pivoted at 2 to a bracket and having two other arms x, . The
upper arm is provided with a fork in suitable bearings in which is supported a
spindle y having at one extremity a hook y¹. y² is a pinion firmly secured upon
the said spindle y and which can be thrown into gear with a toothed wheel y
secured upon the main or longitudinal shaft or arbor a as shown more clearly
in Figures 2 and 4. The arm 2 of the said lever is provided with a weight a
and with a shoe, projection or cam surface x against which a cam z strikes. This
cam is mounted on the spindle jl carrying the worm wheel j.
Directly below the arm of the said lever a¹ is a detent lever E which is pivoted
at El to a cross bar or cross-piece A³ secured to the brackets A². E' is a counter-
weight provided at one extremity of the said lever E. The other extremity of the said
detent lever is provided with a lug or hook E³ which engages with the free extremity of
the said arm of the lever a¹. The cam is also arranged to strike against a surface E*
provided upon the detent lever E during its revolution and throw the said detent
lever E out of engagement with the arm of the lever . F is a slide (more clearly
shown in Figures I and 3) arranged to move freely on ways provided on the bed A.
Projecting from the said slide F is a pin or point F which passes between two strands
of the cord or band D (as shown in the diagrams Figures 12, 13 and 14) and is
carried forward on the twisting of the bands.
G is a bell crank lever the long arm of which is provided with a fork G¹ and forms
a striking gear for shifting the driving belt or band from the fast pulley B to the
loose pulley B' and vice versa. The lever G is pivoted at G2 to a bracket G³ secured
to the bed A. H is a bar or rod arranged so as to be capable of moving freely
to and fro in suitable bearings provided in brackets or bosses H¹ secured to the said
bed A or formed. thereon. The bar or rod H is provided moreover with a projecting
arm H against which strikes the slide F when it reaches a given point as it is pushed
or moved forward by the twisting of the band. The short arm of the lever G is
provided with a slot G in which engages a pin H³ on the said bar or rod H thus
providing for moving or shifting the striking gear or lever G at the required time.
I is a shaft or arbor supported in suitable bearings in brackets I' secured to the bed A,

page_text: 12 is an arm or lever secured upon one extremity of the shaft I and coupled to a lever J.
by means of a connecting rod J¹. The lever Jis pivoted at J2 to one of the
standards A¹ of the machine and carries an adjustable shoe K (as shown more clearly
in Figure 7). The cam z on the shaft or spindle also acts upon the lever J at the
proper time so as to raise or force it upwards and consequently to move or
rotate also the shaft I, through a portion of a revolution. L L are arms or
levers firmly secured to the said shaft I and which pass under a bar o³ provided
on one side of the carriage o. The said arms or levers L lift the said
carriage o when the said spindle I is rotated so as to disengage the pinion q from
the toothed wheel and thus free the shaft or spindle p from the control of the main
or longitudinal shaft or arbor a and thus stop the movement of the said spindle p.
The carriage o can be raised in this manner at different points and at different times
according to the adjustment of the shoe K on the lever J. In order to insure the
stoppage of the machine at the proper time, I provide moreover a spring lever M one
extremity of which is firmly secured by means of rivets, screws or the like to a lug or
projection A on the standard A¹. The spring lever M has an arm or extension M¹ to
which is pivoted at M² a lever N (Figure 4) having at one extremity a wedge-shaped
piece N adapted to pass between the lever M and the cross-bar or cross piece A³.
O is a tooth projection or stop provided upon the said cross-bar or cross piece A³
behind which or engaged with which the spring lever M normally rests. When
however the wedge piece N' is forced between the spring lever and the cross bar or
cross piece A³ the said spring lever M is pushed away from and permitted to pass
the lug, projection or stop O and owing to its elasticity springs forward in the
direction indicated by the arrow in Figure 4. Another projection or arm M³ provided
on the said spring lever M then strikes one of the prongs of the fork G' of the belt
shifting lever G which is extended for this purpose, and shifts the said fork so as to
move the belt from the fast pulley B to the loose pulley B¹ and thus stop the
machine.
The wedge piece N' on the lever N is forced between the spring lever M and the
cross bar or cross piece A³ by the action of the herein before mentioned cam z on the
shaft which strikes against an adjustable arm N2 provided on the other extremity of
the said lever N at a certain point during its revolution and depresses the said
extremity of the lever N as indicated by the arrow in Figure 4 and consequently
raises the other extremity of the said lever and forces the wedge piece N₁ thereon
between the spring lever M and the cross bar or cross piece A³ as hereinbefore
mentioned.
P is a hook, Q is a rod or bar having an eye Q1 at one extremity and a hook Q
at the other extremity thereof and R is a needle having an eye R¹ (as shown in
Figures 9, 10 and 11), S is a stud pin or projection (Figures 1 and 17) upon the
bed A, for receiving the eye R¹ of the said needle R for the purposes hereinafter
described.
The operation of the machine is as follows, that is to say :-The yarn D is placed on
the hooks k¹ and p' as shown for instance in the diagram Figure 12 and the machine
is then set in motion by passing the driving belt or band onto the fast pulley B.
The spindles and hooks k¹ then revolve around their axes in the direction shown
by the arrows in the diagram Figure 13, and twist the two strands D separately,
as shown in the said diagram. During this operation the twisted band becomes
shorter, and consequently the carriage o is drawn or moved forward towards the head
of the machine and also moves with it the toothed wheel r until the friction face³
on the latter comes in contact with the face of the friction disc t on the main or
longitudinal shaft or arbor a. As soon as the said friction disc t comes in contact
with the friction face 3 on the toothed wheel r the latter is rotated and conse-
quently the shaft p is also revolved in the direction indicated by the arrow in the
diagram Figure 14 and through the hook p¹ twists the two strands of the band D
around each other.
During this operation the pin or projection F1 being, between the two strands of the

page_text: said band as shown in the said diagram is forced forward or towards the hooks k! by
the twisting of the said strands.
The hooks ¹ on the spindles k maintain the twist in the strands of the band D
whilst the hook p¹ on the spindle. p twists the two strands together as shown in the
diagram Figure 14. When the strands of the band D are twisted to the point shown
in the diagram Figure 15 the carriage F will have reached a given point depending
upon the twist required and will strike the arm H2 of the rod or bar H thereby
moving the latter and consequently also through the pin H³ the striking lever G and
fork G so as to shift the driving belt or band from the fast pulley B to the loose
pulley B¹ on the shaft C thus stopping the machine.
The outer ends or surfaces of the hooks are grooved as shown in Figures 1 and 8,
so as to allow for the insertion of the hook P (Figure 9) into each eye of the band
without having first to remove the said band from the said hooks. One end of the
said book P is inserted into both strands and the other end is hooked on to the
hook y¹ on the shaft or spindle y or to the hook Q2 upon the bar Q and the eye Q¹
upon the latter is placed on the said hook y' as shown in the diagrams Figures 16
and 17. By providing the hooked bar Q the strand can be more readily handled, and
the hook y¹ can he formed larger and consequently stronger than if the small hook P
be employed without the said hooked bar Q. When the band D is ready for removal
from the hooks k¹ it is in the condition shown in the diagram Figure 15, and as soon
as the said band is removed from the said hooks and is placed on the hook y¹ the
extremity of the needle R is placed between the strands thereof and its eye R' placed
over the stud or pin S which acts as a pivot for the said needle R. The hand lever g
is then operated so as to move the sleeve upon the driving shaft or arbor C and thus
throw the bevel or mitre wheel d out of gear with the bevel or mitre wheel c and at
the same time throw the bevel or mitre wheel i in gear with the said bevel or
mitre wheel c and the worm ' in gear with the worm wheel j on the cam shaft j¹, thus
when the driving belt or band is again shifted to the fast pulley B. the direction of
rotation of the main or longitudinal shaft or arbor a will be reversed and consequently
also that of the shaft or spindle p thus hacking off the twist in the band D at the point
where the needle R passes between the strands thereof. This backing off is continued
until the cam on the cam shaft j' strikes the detent lever E and releases the arm
of the lever carrying the hooked spindle y. The said lever ¹ is then moved
under the action of its arm and weight so as to permit the toothed wheel or
pinion y2 to engage with the toothed wheel y³ on the main or longitudinal shaft or
arbor a by which the said toothed wheel or pinion y and spindle y are revolved
in the direction indicated by the arrows in the diagrams Figures 16 and 17 so as
to retwist the band D whilst the shaft or spindle p and hook p² are untwisting
the said band, thus the needle R will travel between the strands of the band from the
point shown in the diagram Figure 16 and assume the position shown in the diagram
Figure 17 at which point it-passes from between the said strands owing to its being
pivoted to the pin, stud or projection S. The carriage o supporting the shaft p is then
raised by the arms or projections L under the action of the cam z as hereinbefore
described and the backing off motion ceases, the spindle y however still rotating
.continues to twist the band D so as to close the opening made by the needle R and
-consequently harden the said band. The cam then strikes the arm N2 of the lever N
and forces the wedge piece N¹ between the spring lever M and the cross bar or cross
piece A³ so as to release the said spring lever and the driving belt or band is shifted
from the fast pulley B to the loose pulley B' and the machine stopped as hereinbefore
described.
..
During the time the carriage o is raised by the arms or projections L on the
shaft I, and the spindle y and hook y¹ continue to twist the band D, the weight
of the shaft p is sufficient to prevent the said band from causing it to rotate; in
some cases however (if necessary) sufficient friction may be applied through the
medium of its bearings to overcome any tendency it might otherwise have to turn
after its toothed wheel or pinion g is clear of or out of gear with the toothed
wheel on the main or longitudinal shaft or arbor a.

page_text: While the twisting mechanism is being thrown out of gear by the above
described shifting devices the cam z raises the arm of the lever xl and.throws
the pinion y out of engagement with the toothed wheel y the arm x of the
said lever passing again behind and being held in position by the hook E' on
the detent lever E as hereinbefore mentioned. The bevel or mitre wheels d and i
may then be moved to their normal position by means of the hand lever g. and a
new band formed in the manner described above.
