Improvements in Spinning or Twisting and Winding Machines.
We, EDMUND DAWES, of 3632 Frankford Avenue, in the City of Philadelphia,
State of Pennsylvania, United States of America, Cordage Manufacturer, and
ROBERT DAWES, of 5014 Penn Street, in said City of Philadelphia, Mechanical
Engineer, 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 :-
The objects of our present improvements are to automatically regulate the tension
or drag upon the winding spool, to automatically stop the machine when the spool
has been fully wound to prevent the starting of the machine until the tension
regulating devices are in proper position, to provide a simple and effective_form of
traverse guide for laying the rope, cord or strand upon the spool, and to effectively
lubricate the bearings for the draft capstans of the winding flier.
These objects we attain in the manner hereinafter set forth, reference being had
to the accompanying drawings, in which
Fig. 1 is a side elevation of sufficient of the machine to illustrate our present
improvements, part of the frame being shown in section.

of the winding flier.
The flier is driven by a belt from a pulley 2 on the main shaft 3 and the
flanged pulley 4 is carried by a sleeve which is connected to the spool and serves
to retard the rotation of the same under the pull of the cord or rope which is
being wound thereon the said pulley receiving a belt 5 which passes round a
flanged pulley 6 on the shaft 3, this pulley being so proportioned in respect to the
pulley 2 that the spool is driven at a slightly lower speed than, but in the same
direction as the flier, the pulley 4 slipping under the belt 5 at a rate dependent
upon the difference in the speed of the flier and spool, hence the said belt 5 serves
as a frictional retarder for the spool.
This frictional retardation of the spool should be slightest when the winding first
begins and gradually increase in force as the spool becomes filled, and one of the
objects of this invention is to effect such automatic graduation of the friction, an
object which we attain in the following manner.
The machine has a longitudinally reciprocating frame 7 with a guide for the
cord or rope so as to lay the latter uniformly from end to end of the spool, and

page_text: this frame has an arm 8 which engages with adjustable collars 9 on a sliding
bar 10 mounted in suitable guides in the main frame and having ratchet teeth 11
adapted to engage with the teeth of a ratchet wheel 12 on a vertical shaft 13 so
that as the bar 10 is moved in one direction the ratchet wheel 12 will be turned
forward thereby a pawl 14 preventing the said ratchet wheel from moving backward
as the bar 10 is moved in the opposite direction the teeth 11 of the bar then
slipping over the teeth of the ratchet wheel.
By adjusting either or both of the collars 9 on the bar 10 the extent of
movement of the bar on each reciprocation of the frame 7 can be accurately
regulated to accord with the size or character of the cord or rope which is being
wound and to cause a quick slow or medium action of the tension devices. Only
one of the collars need be adjustable.
The shaft 13 is carried in suitable bearings in a hanger 15 and is provided with
a worm 16 which meshes with a worm wheel 17 on a shaft 18 to which is also
secured a cam disk 19 arranged to act upon a lug 20 on an arm 21 which is
pivoted to a stud 22 upon the main frame of the machine and has at the upper
end a flanged pulley 23 which bears upon the belt 5 in its passage between the
pulleys 4 and 6.
The spindle 24 of the pulley 23 is adapted to a segmental slot 25 in the upper
end of the arm 21 and can be secured in any position of adjustment in the said slot
by means of a nut 26 so that the pulley 23 can primarily be caused to bear with
any desired degree of force against the belt 5. When the machine commences to
wind the rope upon the spool, the lug 20 of the arm 21 occupies a position on the
lowest portion of the cam 19 as shewn in Fig. 2 but as the operation of the machine
continues the said cam is turned in the direction of the arrow, Fig. 2 so as to
gradually move the arm 21 inward and cause the pulley 23 to bear with constantly
increasing force against the belt 5 and thus constantly and gradually increase the
friction exerted upon the pulley 4, thereby gradually augmenting the drag upon or
retardation of the spool to accord with the gradually increasing weight of the same
due to the increased diameter of its load of rope cord or strand the lug 20 finally
reaching the highest portion of the cam 19 by the time the spool is fully wound.
The shaft 18 also carries an arm 27 as shewn in Fig. 1 this arm being adapted to
act upon the underside of a shipper rod 28 which controls the driving belt of the
machine. Normally this shipper rod is retained in position to direct the belt to
the fast pulley 29 upon the driving shaft by reason of the engagement of a
shoulder 30 of the rod with a guide bracket 31 on the frame. By the time the
spool is fully wound however the arm 27 has acted upon the shipper rod so as to
lift the same sufficiently to free its shoulder from engagement with the said guide
bracket thereby permitting movement of the shipper rod under the action of a
spring 32 so as to direct the driving belt on to the loose pulley 33 and thus stop
the operation of the machine, the pivot pin 34 of the shipper rod being adapted
to a slot 35 in the frame so as to permit of this longitudi movement of the rol.
After the filled spool has been removed from the machine and a fresh spool
inserted the shaft 13 is turned by means of a hand wheel 36 so as to continue the
forward movement of the shaft 18 and cam 19 until the lug 20 of the arm 21 again
rests upon the lower portion of the cam the tension of the belt 5 tending to move
the arm 21 constantly outward so as to press the said lug 20 towards the face of
the cam.
The same movement of the shaft 18 also carries the arm 27 so far forward
as to permit the lowering of the shipper rod 28 sufficiently to cause it to again
engage with the guide bracket 31 when the said shipper rod has been retracted so
as to again direct the driving belt on to the fast pulley 29 this operation being
effected by hand, but being impossible until the movement of the cam 19 by hand
in the manner before set forth has first been effected hence it is impossible to start
the machine until the tension devices are in normal starting position.
Where the character of the rope cord or strand produced by the machine is

page_text: uniform, and the action of the belt tightener 23 can consequently also be uniform
the cam 19 can if desired be driven in a manner different from that illustrated in
Figs. 1. 2 and 3 for instance the shaft 3 may have a worm 35 meshing with a worm
wheel 36 on a shaft 37 which has a worm 38 as shewn in Fig. 4 for driving the
wheel 17 on the cam shaft 18.
The spindle 40 of the winding flier 1 is tubular and is rotated by means of a belt
leading from the pulley 2 to a pulley 41 on the said spindle a hollow shaft 42
passing through the tubular spindle 40 and having at the inner end a spur wheel 43
for engaging with spur pinions on the draft capstans 44 which are mounted so as
to turn upon spindles 45 carried by the end frame of the winding flier 1.
In a depending bearing on the frame of the machine is mounted a shaft 46 which
has a worm 47 engaging with a worm wheel 48 on a shaft 49 having formed
thereon a right and left hand screw thread for engagement with a shoe carried by
a pin 50 on the traverse frame 7, the latter being grooved for the reception of a
ring 52 mounted upon the rods 1 of the winding flier, this ring carrying the guide
for the rope, cord, or strand which is being spun or twisted so that the said guide
both rotates with the flier and is moved longitudinally to and fro from end to end
of the spool in order to lay the rope, cord or strand properly thereon.
In order to simplify and cheapen the construction of the guide ring we make
the same simply in the form of a flat ring of steel and connect the same to the
longitudinal rods of the winding flier by means of shoes 53 which partially
embrace the said rods and have projecting ears or lugs 54 which are secured by
means of hollow bolts 55 to corresponding ears or lugs on the inner face of the
ring 52 as shewn in Fig. 8. either of these hollow bolts performing the additional
function of a guide for the rope, cord or strand which is being formed so that the
provision of a special and separate guide is rendered unnecessary.
The spindles 45 upon which are mounted the draft capstans 44 of the winding
flier are hollow as shewn in Fig. 11 each spindle having at one end a head or
flange 56 bearing against the outer plate of the end frame of the winding flier, the
opposite end of each of the hollow spindles 45 being threaded internally for the
reception of the externally threaded portion of a hollow plug 57 which has formed
in it a right angled passage communicating with the interior of the hollow spindle,
the radially extending portion of this passage being closed in any suitable manner,
as for instance by means of a screw 58, as shown in Fig. 11.
Provision is thus afforded for readily filling the hollow spindle 45, with oil,
grease, or other lubricant, which can gain access to the bore of the draft capstan,
through an opening 59, in the said spindle so as to provide for the proper lubrication
of the said draft capstan for long periods without attention.
The hollow spindle preferably contains a loose filling of cotton waste, wicking
or the like from which the lubricant can drain slowly, so as to properly provide the
lubricant to the bearing and prevent any excess of such supply.

tion and in what manner the same is to be performed we declare that what we
