"IMPROVEMENTS IN MACHINERY FOR TWISTING OR FORMING AND LAYING
STRANDS, CORDS, OR ROPES."
This Invention consists of a novel arrangement of machinery for giving a positive
take up to the reel or bobbin upon which the strand or rope is wound when
being twisted, so that a regular twist is obtained and a rope of uniform thickness
is produced.
The reel or bobbin upon which the strand or rope is wound is carried in a flyer,
the axis of the bobbin or reel being at right angles to the axis of the flyer, the
object of this Invention being to give a positive motion to the bobbin or reel,
varying exactly according to its diameter, and without the interference of any drag
or uncertain take up.
The bobbin or reel is connected by gearing to a bevil wheel at the opposite end
of the flyer to that at which the strand or rope is admitted, and the revolution of
the flyer round this bevil wheel (which varies in its speed of rotation as the diameter
of the bobbin increases with the winding on of the strand or rope) actuates the
bobbin or reel accordingly.
The various speeds required at each layer are communicated to the centre bevil
wheel in the flyer by a novel arrangement of spur gearing which gives a positive
change as follows:-Connected with the flyer by suitable gearing is a series of
pinions on one shaft corresponding to the number of layers of rope to be received
onto the reel or bobbin. These pinions are of different diameters and gear into
corresponding pinions upon another shaft, either directly or through carrier wheels.

is loose, being carried upon a hollow shaft furnished with a series of keys, one to
each pinion. These keys are made to connect to the shaft the pinion that is
necessary to give the correct speed to the centre bevil wheel in the flyer, so as to
produce, in conjunction with the revolutions of the flyer round it, the required
positive take up by the reel or bobbin.
This arrangement of pinions of different diameters is applicable to other purposes
where a positively varied motion is required capable of changing the speed without
stopping the mechanism.
In laying ropes or cords formed of twisted strands, the bobbins carrying the 1
strands are caused to revolve at right angles to their axes, being carried in flyers
or carriages, to which motion is given by suitable gearing direct from the flyer
which carries the reel upon which the rope is wound.
By these means. a regular twist is obtained, and it is positively maintained
throughout the length of the rope or cord.

SAMUEL WILSON, Ship Chandler, of Belfast, in the County of Antrim, Ireland.
IMPROVEMENTS IN MACHINERY FOR TWISTING OR FORMING AND LAYING
STRANDS, CORDS, OR ROPES."
This Invention relates to improvements in machinery for twisting and laying the
strands of cords and ropes, and consists in giving a positive "take-up" to the reel
or bobbin upon which the strand or rope is wound when being twisted, so that a
perfectly regular twist is obtained and a rope of uniform diameter is produced.
The nature of this Invention will be understood from the following description,
reference being had to the accompanying Drawing, in which the same figures and
letters of reference always apply to the same or like parts.
Fig. 1 is a side elevation of the machine; Fig. 2 is an end elevation; and Fig. 3
is a plan view of the same; Fig. 4 is a partial plan view shewing the opposite side
of the flyer to that seen in Fig. 3; Fig. 5 is a section of the bobbin flyer and
gearing thereon; Figures 6, 7, 8, 9, and 10 are enlarged views of the wheels, socket,
and their connections, by which the axial motion of the bobbin is controlled.
b is the reel or bobbin upon which the strand or rope c is wound.
It is carried
in a flyer a, the axis of the bobbin or reel being at right angles to the axis of the
flyer.
The object of this Invention, which is to give a positive motion to the bobbin or
reel b varying exactly according to the diameter of the bobbin b without the inter-
ference of any drag or uncertain "take up" motion I effect in the following manner,
vis-I connect the bobbin b by gearing 61 to a bevel wheel c, which is mounted
on a spindle that runs through the hollow journal of the flyer, such bevil wheel
being situate at the opposite end of the flyer a to that at which the strand or rope e
is admitted to the flyer. The revolution of the flyer a and its gearing b¹ around
the bevil c (which is driven, as will be presently explained, at a different speed
at cach layer put upon the bobbin b or reel) actuates the bobbin 6 or rcel
accordingly.
•
The various speeds of the bobbin b required at each layer are communicated to
the centro bevil wheel c in the flyer a by a novel arrangement of spur gearing
which gives a positive change, and is as follows:-
Connected with the flyer a by suitable gearing a¹ is a series of pinions f, of
varied diameters, and mounted loosely on a hollow shaft or socket f¹, the number
of pinions corresponding to the number of layers on the filled reel or bobbin b.
These pinions f, whose varied diameters correspond to the increase in diameter of
the bobbin for every additional layer of strand or rope, gear into corresponding
pinions g keyed upon a shaft g', either directly or, as shown in the Drawing, through
carrier wheels g². These driven pinions g communicate the different speeds to the
bevil wheel c in the flyer a through a train of spur gearing cl The hollow
shaft f' which carries the pinions fis fitted with a series of keys 2, one for each
pinion f. These keys f² serve to connect that one of the pinion to the hollow
shaft or socket f¹, which is necessary to give the required speed to the centre
bevil c in the flyer a, so as to produce, in conjunction with the revolutions of the
Ayer a round the bevil pinion c, the required positive "take up" by the reel or
bobbin b.
The different pinions fare connected to the socket f¹ one after the other by the
keys f³ being pushed up through the socket into connection with internal teeth
in the pinion, as shewn in section in Figures 7, 8, and 10, by means of a grooved

page_text: sliding bar fs, which is moved endwise at the completion of each layer on the
bobbin b by a rack h attached thereto, and geared into by a pinion h¹ keyed to a
short transverse shaft which turns in bearings in the framing. This pinion is
turned a part of a rotation corresponding to the distance from the centre of one
pinion to the next by means of a weight h2 pendent from a chain on a pulley a
keyed to the pinion shaft which is held by a ratchet wheel i with which one or
other of two catches, ¹, are in gear, such retaining catches being relieved
alternately by a bar a² mounted transversely in the flyer, striking the catches i¹
alternately as the flyer a revolves. This bar a is free to receive an endway motion
in the flyer, and is shot out at the completion of each layer upon the bobbin b by:
means of the traversing guide striking tappet screws on the bar a² assisted by a
wedge as forced by a spring into contact with a corresponding wedge a* on the
bar a².
The bobbin or reel b is shewn as commencing the operation of winding on,
and the pinions. f. and their connecting keys are also shewn at the beginning
of the process of winding on and twisting the first layer of the strand or rope c.
The number of the pairs of pinions fand g, it will be understood, must correspond
with the number of layers upon the bobbin 6 to obtain accurate results, and they
will bear the same relation to each other that the surface speed of the bobbin at
each layer has to the revolutions of the flyer. It will require therefor a different
group or set of pinions for each different size of strand or rope that is made.
This arrangement of pinions of different diameters is applicable to other purposes
where a positively varied motion is required, capable of changing the speed without
stopping the mechanism.
In laying ropes or cords formed of twisted strands, the bobbins or spools carrying
the strands are caused to revolve at right angles to their axes, being carried in
Hyers or carriages, to which motion is given by suitable gearing direct from the
the flyer which carries the reel upon which the rope is wound when twisted.
By these means a regular twist is obtained, and it is positively maintained
throughout the length of the rope or cord.
Having now set forth the nature of my Invention of " Improvements in
Machinery for Twisting, Forming, and Laying Strands, Cords, or Ropes," and
having explained the manner of carrying the same into effect, I wish it to be under-
stood that under the above in part recited Letters Patent, I claim,―
The use of a series of pinions of different diameters for the purpose of imparting
a positive "take-up" to the bobbin, the axial motion of the bobbin being varied in
speed as each layer is put upon it by the means above described.

In witness whereof, I, the said Samuel Wilson, have hereunto set my hand
and seal, the Sixteenth day of April, in the year of our Lord One thousand
eight hundred and eighty one.
