Improvements in Machines for Producing Twisted Wire.
We JAMES PATCHETT and PERCY PATCHETT, Ironinasters, of Hadley, near
Wellington, Salop, do hereby declare the nature of this invention to be as follows:-
Our invention has for its object to put a twist or spiral surface upon a coil or length
of wire for use in making nails and similar articles, and to accomplish this by attaching
our improvements to an ordinary wire strand machine, either vertical or horizontal,
or by means of a special machine or mill constructed according to our improved
method for twisting the wire.
In carrying our invention into effect when twisting a coil of wire by means of an
ordinary wire strand machine, we place our wire that is to be twisted upon one bobbin
upon the frame of the machine, which bobbin in the ordinary working of the machine
is stationary, while the frame carrying the bobbin revolves. But, our invention
consists in causing this bobbin to rotate or revolve with the frame by means of clamps
or clips which connect the bobbin to the distance bolts or side bars of the machine.
We employ any well known or ordinary method for connecting the bobbin to the
rotating parts of the machine such as causing it to he keyed to the central spindle of
the machine, or causing a clutch upon the spindle to engage with a corresponding
clutch upon the bobbin.
We regulate the amount of spiral or twist which we give to the wire by means of
change gearing wheels, which cause the wire to be drawn out of, or away from the die
or fixed twisting head of the machine or mill at a rate which will cause a certain
determinable degree of twist upon the length of wire between the fixed head and the
revolving bobbin, that is to say the ratio of withdrawal of the wire to that of the
revolution of the bobbin we may vary so that a greater or lesser degree of twist may
be obtained.
In large mills we arrange a series of bobbins to be worked from one driving shaft,
with a frame having a number of bobbins arranged thereon, and a number of reels to
wind each length of wire from off its own particular bobbin after the twist has been
given it in the machine by revolving the bobbin and permitting the head or die to
remain stationary.
We employ our spiral or twisting arrangements upon an ordinary strand mill by
permitting the first bobbin only to revolve and not placing bobbins in the frame
immediately behind it, so that we need not of necessity use any special machine for
twisting a coil although we prefer to employ a small machine for that purpose only,
instead of the ordinary wire stranding mill, or mill used for laying the coils into a
rope.
We adapt our improvements to any type of wire winding or stranding machine
with similar advantage.

Wo JAMES PATCHETT and PERCY PATCHETT Ironmasters of Hadley near
Wellington Salop 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 :-

In carrying our-invention into effect when twisting a coil of wire by means of an
ordinary wire strand machine, we place our wire that is to be twisted upon one bobbin
upon the frame of the machine which bobbin in the ordinary working of the machine
is stationary while the frame carrying the bobbin revolves. But our invention
consists in causing this bobbin to rotate or revolve with the frame by means of clamps
or clips which contact the bobbin to distant bolts or side bars of the machine.
employ any well known or ordinary method for connecting the bobbin to the rotating
parts of the machine such as causing it to be keyed to the central spindle of the
machine, or causing a clutch upon the spindle to engage with a corresponding clutch
upon the bobbin.
We regulate the amount of spiral or twist which we give to the
wire to be drawn out of or away from the die or fixed twisting head of the machine or
mill at a rate which will cause a certain determinable degree of twist upon the length
of wire between the fixed head and the revolving bobbin, that is to say the ratio of
withdrawal of the wire to that of the revolution of the bobbin we may vary so that a
greater or lesser degree of twist may be obtained.
In large mills we arrange a series of hobbins to be worked from one driving shaft
with a frame having a number of bobbins arranged thereon and a number of reels to
wind each length of wire from off its own particular bobbin after the twist has been
given it in the machine by revolving the bobbin and permitting the head or die to
remain stationary.
We employ our spiral or twisting arrangements upon an ordinary strand mill by
permitting the first bobbin only to revolve and not placing bobbins in the frames
immediately behind it, so that we need not of necessity use any special machine for
twisting a coil although we prefer to employ a small machine for that purpose only,
instead of the ordinary wire stranding mill or mill used for laying the coils into a
rope.
We adapt our improvements to any type of wire winding or stranding machine with
similar advantage.
In order that our invention and the manner of performing the same may be properly
understood and readily carried into effect we append hereunto one sheet of explanatory
drawings to be bereinafter referred to.
Figure 1 is a sectional elevation of our improved wire twisting mill or machine.
Figure 2 is a plan of the same and
Figure 3 is a sectional end elevation showing the bobbin and frame.
Figures 4 and 5 are short lengths of wire as twisted in our machine, the one
triangular and the other square in section.
A, A are fast and loose pulleys arranged upon the spindle a of the machine;
BB are circular frames or rings between which the bobbin C and the bobbin
frame C is placed.
The bobbin C and bobbin frame C we construct in the usual, or any well known
ordinary manner D, D D are distance pieces or bolts for connecting the frames B B₁
together, E is the fixed die or plate through which the wire passes and which guides
it to the end pulley F; G is the winding drum or reel carried upon the shaft g;
H, H', H² are change gearing wheels which we alter or arrange to give more or less
twist to the wire as inay be required. K is the worm wheel into which the worm k
works, which worm is carried securely by the shaft or spindle a of the machine.
L, L' are quadrant or adjustable brackets for carrying the spindles h h of the change
wheels, and also for carrying the spindle g of the winding drum or reel. M. M¹ M'
are guide or bearing rollers for supporting the circular frame B'; N, N is the bed or
base of the machine and O, O' are the supporting legs or brackets for carrying the
same. P is the bracket for carrying the guide pulley F.
The bobbin frame we cause to revolve as one with the spindle a by keeping the
end of the frame C2 on to the spindle, or by securing it. by keys or set screws to the
boss of the circular frame B' which circular frame B₁ we cause to be rigidly connected

page_text: to the spindle a.
Sometimes instead of keeping or securing the bobbin frame to the
spindle or circular frame, we cause it to be clipped or connected to one or more of the
distance bolts D, and thus to revolve with them.
The action of our machine is as follows,-
The wire to be twisted is placed upon the bobbin Cand connected to the machine
as before described, the end of the coil upon the bobbin is then led through the
fixed die or guide plate E and round the end pulley F on to the winding drum or
reel G to which it is attached; the machine is then set in motion and as the bobbin C
revolves the wire is drawn through the fixed plate E on to the reel or drum G ; the
ratio of withdrawal to the speed of revolution determining the amount of spiral or
twist which is given to the wire. The ratio of withdrawal to the speed of revolution
we can alter to suit any particular requirement when a greater or lesser spiral is to
be obtained.
Sometimes instead of constructing a new machine for twisting the wire alone we
utilize the existing mill for stranding wire into cable or rope form, in which case we
cause the front bobbin nearest the outgoing end of the machine to be securely attached
to the connecting bolts or distance pieces between the circular revolving frames of the
machine and thus to revolve as one piece with the frames of the machine.
from the bobbin we carry through a fixed plate arranged upon, or near the end of the
The wire
machine, and from this plate we take it to the guiding pulley, which directs it on to
the winding drum; in this case also revolving at a determined speed by a suitable
arrangement of the change wheels ordinarily employed upon the stranding machine.
When thus employing the stranding machine as a plain or single wire twisting
machine we do not require to use the whole length of the machine seeing that but one
bobbin is employed; but from the. construction of the machine the whole length of
framing is caused to revolve and thus a waste of power is caused. We therefore do
not adopt this method of twisting wire when any large amount is to be operated
upon but prefer to employ instead our special twisting machine as hereinbefore
described.
We construct our wire twisting machine so that it may be used as a horizontal or
vertical machine as may be desired.
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
ve claim is―
I. The construction of a wire twisting machine in which the wire is twisted as it
s wound off the bobbin on to a reel or drum driven by the gearing of the same
machine.
II. The construction of a wire twisting machine having change wheels to vary the
atio of the twist or spiral formed upon any determined length of the wire substantially
s herein before described and illustrated in the accompanying drawings.
III. The arrangement and construction of a wire stranding machine capable of
eing converted into a wire twisting machine by means of the alteration to the driving
nd carrying arrangement of the bobbin substantially as hereinbefore described
nd for the purposes set forth.
