Nottingham, Nottinghamshire, Moulder do hereby declare the nature of said
Invention for "IMPROVEMENTS IN MACHINERY FOR DOUBLING AND TWISTING
YARNS AND THE LIKE" to be as follows, that is to say :-
This Invention relates to machinery employed for doubling and twisting yarns
and other material requiring to be doubled or twisted and it has for its object the
construction or arrangement of such machinery in an improved and economical
manner, so as, whilst effecting a saving of material, to render such machinery
capable of performing the operation of doubling and twisting in a more rapid,
Batisfactory and efficient manner than is possible with the machinery at present
generally used.
In carrying out the Invention, the long and costly spindles for carrying the
bobbins or spools and the drum for driving the same are dispensed with and
instead of them the machine is arranged with a horizontal first-motion shaft,
having at suitable distances along it a series of disc-wheels. Above these disc-
wheels there are arranged to be carried by a suitable part of the framing a series
of short spindles, there being two (or more) spindles to each disc-wheel one on each
side of the disc-wheel shaft. These spindles are carried in tubular bearings in which
they can revolve and have a braid piece having a projection on its upper surface
for engaging with a bobbin, whilst its underside has a ring of, or is covered with,
leather or other suitable substance. When the spindles are placed in their tubular
bearings the under and leather covered sides of the braid pieces rest upon the edges
of the disc-wheels and are consequently driven by friction when motion is given to
the disc-wheel shaft. Or instead of being driven by friction, the bobbins may be
driven by gearing. Instead of the flyers having long arms as formerly, there is
arranged to be placed on each bobbin on the spindles, a metal disc having projecting
beyond its edge a short piece of wire terminating in a curl or twist. The yarn or

Engineer, and AARON SAMUEL BRINDLEY, 30 New Norton Street, New Radford,
Nottingham, Nottinghamshire, Moulder, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR DOUBLING AND TWISTING
YARNS AND THE LIKE," and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement that is
to say:
Our said Invention relates to machinery employed for doubling and twisting
yarn and other material requiring to be doubled or twisted and it has for its object
the construction or arrangement of such machinery in an improved and economical
manner so as, whilst effecting a saving of material to render such machinery
capable of performing the operations of doubling and twisting in a more rapid,
satisfactory, and efficient manner than is possible with the machinery at present
generally used.
In carrying out our said Inventions the long and costly spindles for carrying the
bobbins or spools and the drum for driving the same are dispensed with, and
instead of them the machine is arranged with a horizontal first motion shaft,
having at suitable distances apart along it a series of disc wheels. Above these
disc wheels there are arranged to be carried by a suitable part of the framing a
series of short spindles, there being two (or more) spindles to each disc wheel, one
on cach side of the disc wheel shaft. These spindles are carried in tubular bearings
in brackets fixed on the framing in which the spindles can revolve, and the spindles
have each, a braid piece having a projection on its upper surface for engaging with
a bobbin, whilst its under side has a ring of (or is covered with) leather or other
suitable substance. When the spindles are placed in their bearings the undersides
of the braid pieces rest upon the edges of the disc-wheels and are consequently
driven by friction when motion is given to the driving or disc wheel shaft. Instead
of being driven by frictional contact the bobbins may be driven by gearing.
Instead of the flyers having long arms as formerly there is arranged to be placed.
on each bobbin on the spindles, a metal disc having projecting beyond its edge a.
short piece of wire terminating in a curl or twist. The yarn or material to be
operated on is led from the bobbin on the spindle through the disc-flyer curl up
over a guide pulley carried on the framing above the spindles. Thence the material.
is led down and passed first round the narrower part of a conically formed boss on
a shaft driven by suitable gearing (the speed of this shaft may be regulated by.
change wheels) then round a small pulley in front and back again round the boss,
which it again leaves at its thickest part, and is next passed over the usual guide.
rail to the bobbin or spool on which it is to be wound. This conically formed boss
forms what may be termed a differential drag roller. If found preferable or
convenient the driving or friction discs may be fixed on a counter shaft instead of
being on the first motion shaft and be driven by suitable gearing.

page_text: And in order that our said Invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and representing a modification of our improved
apparatus for winding and twisting.. In these drawings the same reference numerals
are used to mark the same or like parts wherever they are repeated.
Figure 1 on the accompanying sheet of drawings is a cross section of our
improved machine which is arranged for performing the winding and twisting
operations simultaneously on each side of the machine, one side of the machine
being practically a counterpart of the other. Figure 2 is a front elevation of part
of the machine, showing two spindles only, whilst Figures 3 and 4 are enlarged
views of details to be hereinafter described. The material to be operated on is
carried by bobbins 1 which are placed on spindles 2 arranged to project radially
upwards from about the middle of the machine towards the back and front or sides.
The construction and arrangement of the spindles 2 will be best understood by
referring to Figure 3 which is a sectional elevation of a spindle and the parts
immediately connected therewith. This spindle 2 is formed straight and of uniform
diameter and it has fixed at about the middle of its length a braid piece 3 having
a projection on its upper side and having its underside fitted with a ring 4 of
leather or other suitable substance This braid piece 3 partly encircles the upper
end of a tubular bearing 5 for holding the spindle which bearing is carried by a
bracket fixed on the framing at a convenient height from the ground, and above
a first motion shaft 7. This first motion shaft 7 is carried in bearings on the
framing, the centre of its axis being at the point whence the axes of the radial
spindles radiate, and it has fixed upon it at short distances apart along it, disc or
frictional driving wheels 8. There is a driving wheel 8 to each pair of spindles 2
along the machine, the leather covered undersides of whose braid pieces 3 rest on
the peripheries of the driving wheel when the spindles are in position in the
brackets 6 the spindles being thus driven by friction on the revolution of the
driving wheel to which motion is given in an ordinary manner. The yarn in
the case of each spindle along the machine is led from the bobbin 1 upwards and
is passed through flyer curls 9 formed in the ends of wires which project
diametrically from each other from a small metal disc or boss 10 fitted so na to
screw on the spindle 2 over the bobbin when the spindle revolves. The yarn next
passes upwards over a pulley 11 carried in bearings on a bracket 12 fixed to upward
extensions 13 of the framing. Thence it passes downwards and round one part of
a differential drag pulley or boss 14 fixed on a shaft 15 running the length of the
machine there being a pulley 14 for each spindle and a slinft 15 at each side of the
machine. This shaft 15 on each side is carried in bearings formed on short
uprights 16 fixed on the main framing so that the shaft 15 is on a level with about
the middle of the bobbin 1 and a short distance in front. This shaft 15 has suitable
motion given to it by gearing at the end of the machine connected with the first
motion shaft and the motion may be altered to vary the twist or suit different
requirements by means of change wheels in a well known manner. After passing
round this differential drag roller which will be best understood by referring to
figure 4, which is an enlarged view in longitudinal section of one pulley or boss 14.
It will be seen that this pulley 14 has two bearing surfaces, one of which is of
slightly larger diameter than the other, and it is round the smaller of these two
surfaces that the yarn is first passed. From this surface the yarn is passed round
a small pulley 17 fitted at the upper end of a short vertical rod 18 fixed on the
framing just in front of and with the pulley 17 level with the shaft 15. The yarn
is again passed back and round the larger of the two bearing surfaces of the drag
roller both of which surfaces are covered with rubber or other suitable frictional
material, and from this drag roller the yarn passes over a guide rail (to which the
Usual suitable reciprocating motion is given by mangle wheel arrangements in a
well known manner) to a bobbin or receptacle 19. This bobbin 19, is carried by a
short peg 20 provided with a suitable braid piece 21, having its underside covered
or partly covered with a suitable frictional material such as leather. This braid'

page_text: piece 21 rests upon the periphery of a small disc or driving wheel 22, which is
fixed upon a horizontal shaft 23, extending along the machine at the front and
carried in bracket bearings 24 fixed on the framing. Motion is given to this
shaft 23 by suitable gearing connected with the first motion shaft so as through the
driving wheels 22 to turn the bobbins 19. and wind the twisted yarn suitably
thereon. It will be understood that there is a similarly arranged driving shaft 23,
at each side of the machine each shaft having a driving or disc wheel fixed upon it.
to correspond to each spindle 2 along the frame. In order to stop each spindle on
each side when required for doffing or piecing there is arranged a horizontal rod 25
to each spindle this rod being carried on the framing and extending transversely
from the middle of the machine to the outside. The outer end of this rod 25 lying
just under the spindle 20 conveniently for the attendant's hand and its inner end
is formed with a flat vertical enlargement. This flat enlarged end has a curved slot
formed in it in the direction of its length and is also formed with a cam part or
upwardly curved projection. The inner end of the rod 24 is fitted to the bracket
piece 6 by means of a headed pin passing through its slot in such a position that
when the rod is pulled forward or outward by the worker the cam part is brought
by the action of the pin in the curved slot, against the bottom of the braid piece,
which is thus lifted out of contact with the driving or disc wheel 8 a small bent
part 26 being fixed on the bracket 6 so that its bent or upper end presses against
a flange or part on the braid piece when it is raised as just described, and acts as a
brake.
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) The combination and arrangement of parts of apparatus forming a winding
and twisting machine substantially as herein before described with reference to the
accompanying drawings.
