Improvements in Machinery or Apparatus suitable for the Manufacture
of Cords for Upholstery and other purposes.
We, ALFRED MELSON & COMPANY, LIMITED, of Claremont Works, Bethnal
Green, in the County of London, Trimming Manufacturers, and ALFRED MELSON
and GEORGE EDMUND LYONS, both of Claremont Works aforesaid, and Managing
Director and Manager, respectively, to the said Alfred Melson and Company, do
hereby declare the nature of this invention to be as follows:-
-
This invention relates to machines suitable for the manufacture of cords for
upholstery and other trimmings of the kind in which a core or "gut" is covered
by a thread or threads wound or spun thereon.

و,
In apparatus for this purpose according to this invention a bobbin or the like
containing a core is mounted on a suitable rotary support whence the core passes
to a twisting device by means of which the covering thread or threads is or are
wound or spun
upon it and from which the covered core passes to a bobbin
or the like upon which it is wound; the rotary support and the twisting device
have the same direction of rotation, the latter rotating either at the same speed
as the former or slightly faster than the former so as to impart a slight twist to
the core.
In one example of apparatus according to this invention each core bobbin is
mounted on a cross piece carried by a fork at the top of a hollow vertical spindle
on the lower end of which is fixed an inverted flyer, and the core is passed down
inside the spindle and to the outer end of one of the legs of the flyer, where it
passes partly round a guide pulley. The core passes from this guide pulley
around the corresponding leg of the flyer and then partly round a guide pulley
mounted in the lower end of the spindle or the flyer, whence it proceeds down-
wards to a flyer carried by a second spindle, being joined on its passage thereto
by the covering threads, which reach it from bobbins mounted in a suitable
creel and are suitably guided near their juncture with the core. The covered
core passes down one of the legs of the flyer and partly around a guide pulley at
the outer end thereof to a bobbin mounted on the spindle of the flyer, on which
it is wound. The two spindles are driven in the same direction by means of
bands from a common drum or separate drums and the one carrying the core
bobbin at a slightly less speed than the other spindle; the bobbin on which the
covered core is wound engages with a wharl rotated at a suitable speed to take
up the covered core, by means of a band from one of the said drums or a separate
drum. The example just described might be modified by the omission of the
upper flyer in that case a suitable tension device might be substituted therefor.
It will be obvious that in lieu of the flyer twisting device, a ring and traveller
twisting device may be used.

and GEORGE EDMUND LYONS, both of Claremont Works aforesaid, and Managing

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 follow-
ing statement:-

gut" is covered
In apparatus for this purpose according to this invention a bobbin or the like
containing a core or "gut" (hereinafter called a core) is mounted on a suitable
rotary support whence the core passes to a twisting device by means of which
the covering thread or threads is or are wound or spun upon it and from
which the covered core passes to a bobbin or the like upon which it is wound;
the rotary support and the twisting device have the same direction of rotation,
the latter rotating either at the same speed as the former in order not to twist
the core or slightly faster than the former so as to impart a slight twist to
the core.
An example of a machine according to this invention is represented somewhat
diagrammatically in Figs. 1, 2, and 3 of the accompanying drawings, which are
respectively a broken sectional front elevation, a sectional end elevation, and a
broken plan thereof. In the example, each core bobbin a is mounted at the top
of a hollow vertical spindle b, and the core c, after being suitably guided from
the bobbin, passes down inside the spindle b and through a hole in the wall of
the spindle and under and over two tension pulleys e and f respectively which
are mounted on a balanced arm g fixed to the spindle b. The core passes from
the outer pulley f to a guide pulley h mounted in the lower end of the spindle b
and after passing partly round this guide pulley it proceeds downwards to a
flyer i carried by a second spindle j, being joined on its passage thereto by the
covering threads k which reach it from bobbins m mounted in a creel n and are
suitably guided near their juncture with the core. The covered core passes
partly round a guide pulley p mounted in the upper end of the flyer i and then
down one of the legs of the flyer and partly around a guide pulley q at the outer
end thereof to a bobbin r mounted on the spindle 3, on which it is wound, the
building of the covered core on the bobbin being accomplished by mechanism
such as ordinarily used in spinning and twisting machines. The two spindles b
and j are driven in the same direction by means of bands s and t from separate
drums and v respectively, the one carrying the core bobbin at a slightly less
speed than the other spindle; the bobbin on which the covered core is wound
engages with a wharl w rotated at a suitable speed to take up the covered core,
by means of a band from the drum v; the bands s and a are guided and kept
at a suitable tension by grooved pulleys y mounted on weighted levers z.. The
device for guiding the threads k to the core c, which is shown in perspective in
Fig. 4, comprises a bent strip o having a hole o¹ and a notch o², a bar o³ which is
provided with a screw shank o' for attaching it and the strip o to the frame of
the machine and with a V-shaped groove o³ on its face and upper end, and a bent

page_text: wire of resting against the upper end of the bar o³ to which it is attached by a
screw o; the covering threads & pass through the notch o, over the wire o",
which arranges them one above another, and through the portion of the groove o
in the upper end of the bar o³ to the core, which passes through the hole o¹ and,
afterwards receives the threads k, and passes along the vertical portion of the
groove 5. The pulley f of the tension device, instead of being mounted in a
simple arm g, as is preferred, may be carried by one leg of an inverted flyer 1 as
shown in Fig. 5. Fig. 5 also shows the core bobbin mounted on a cross piece 2
carried by a fork 3 at the top of the hollow spindle b, the core passing from the
bobbin through a guide 4 and over a pulley 5 mounted on an arm 6, which is
fixed to the fork 3 and is provided with holes through one or more of which
(as required to produce the necessary drag) the core passes before entering the
spindle b; in the example shown in Figs. 1, 2, and 3, each bobbin a is, as
preferred, placed over a vertical pin 7 projecting upwards from an inverted flyer 9
which comprises a disc 10 for supporting the bobbin and carries a thread guide 11
and a pulley 12 through and partly round which the core passes to a hole 13 in
the flyer and thence to the interior of the spindle b, the flyer being screwed upon
the spindle, in a direction opposite to that of the rotation of the latter, to facili-
tate the threading of the core through the spindle; the latter arrangement gives
a better balance and is more convenient than the former and is also somewhat
simpler.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. Apparatus for use in the manufacture of cords in which a bobbin or the
like containing a core is mounted on a rotary support whence the core passes to
a twisting device by means of which a covering thread or covering threads is or
are wound or spun upon it and from which the covered core passes to a bobbin
or the like upon which it is wound.

2. In apparatus for use in the manufacture of cords of the kind in which a
core is covered by a thread or threads wound or spun "thereon, the combination
of a hollow support adapted to carry at its upper end a bobbin or the like con-
taining a core, a tension device, a twisting device, means for guiding the covering
thread or threads to the core, a spindle adapted to carry a bobbin for receiving
the covered core, and means for winding the core on the latter bobbin and
rotating the hollow support and the twisting device in the same direction, sub-
stantially as set forth.
3. The improved machinery or apparatus for the manufacture of cords, con-
structed, arranged, and operating as herein before described with reference to
and shown in Figs. 1 to 4 inclusive of the accompanying drawings.
