Improved Means for Paying Out Wire from Wire Coils and for
Controlling the Length of Wire Paid out.
I, SAMUEL WILLIAM JOHNSON, of 1, Oxford Place, Clifton Road, Aston
Warwickshire, Engineer and Machinist, do hereby declare the nature of this
invention to be as follows:-
This invention consists of the herein described improved means for paying out
wire from wire coils and for controlling the length of wire which has been paid out
my invention being applicable for use with inachines for forming small wire coils or
springs for mattresses and for other purposes from a large wire coil and with
machines for winding wire on to bobbins of wire netting machines and for use
with other machines in which wire is operated upon. By my invention the wire as
it is unwound from the long coil (which latter is stationary) turns an arm which
gives motion to gearing which latter in turn operates a tappet which when it has
reached a certain predetermined position corresponding with the required length of
wire which has been paid out from the coil releases or operates the strap fork bar
or clutch bar or other device for stopping the wire coiling or other machine with
which my invention is used thus bringing the machine to rest and causing the wire
coil or wire spring to be made exactly the length required.
According to one arrangement of my invention I provide a circular or other base
of a size to take the large coil of wire which is to be used up in the machine this
said wire coil lying on the base in a horizontal position. Standing up from the
centre of the said base there is an axis carrying the said arm and about which the
arm is revolved by the wire as it is paid out this wire passing through a guide
carried by the arm and then round or partly round a roller at the outer end of the
arm and under other guide rollers to the top of the centre axis where it passes
through an eye or between guide rollers and then on away to the machine by which
the wire is made into coils or otherwise used up so that as the wire is drawn from
the coil the arm will thereby be caused to revolve. Mounted upon a sleeve on this
arm there is a small pinion which gears with a stationary toothed wheel ring
supported from the base. Upon the same sleeve there is another pinion which can
be moved to and fro along the sleeve on the arm so as to gear with one or other annular
sets of teeth holes pegs or other like devices arranged on a face wheel which is free
to revolve about the central axis of the base above referred to. Fixed to this face
wheel is a tappet so arranged in combination with the strap fork bar clutch bar or
other means for stopping the machine which is using up the wire paid out from the
coil that when this tappet reaches a certain position the strap fork bar clutch bar
lever or other means for stopping the machine is released or moved so as to move
the main driving band on to the loose pulley or to throw out the clutch and thus
stop the machine when the required length of wire has been unwound from the
large coil. In order to regulate the length of wire which is paid out from the coil
before the machine is stopped one of the said pinions has to be moved along the
sleeve so as to gear with a larger or smaller circle of teeth holes pegs or other
devices on the face wheel and thus cause the part carrying the tappet to revolve
slower or faster and thus stop the machine when a longer or shorter portion of the
wire has been paid out from the coil.

page_text: The tappet which releases the strap fork bar clutch bar or other means for
stopping the machine which is using up the wire paid out from the coil may either
be fixed directly to the said face wheel or arranged on a separate wheel disc or arm
revolving about the axis and controlled by a spring thereon. In this case I provide
on the underside of the said face wheel a small disc which is roughened or provided
with ratchet teeth immediately above the tappet so as to engage therewith and
carry the tappet round through a certain angle when the wire is being paid out
from the coil then when this tappet releases the strap fork bar or other stopping
device of the machine this bar on being released strikes a tail of the tappet and
releases the tappet from engaging with the ratchet teeth or roughened disc so that
the ratchet is then free to be caused to fly back round the axis by a spring therein
as far as an adjustable stop will allow. By means of this stop which is by
preference carried on a stationary circular plate or bar round the axis the angle
through which the tappet moves before it releases the strap fork bar and con-
sequently the length of the wire paid out to the machine can be adjusted as
required.

Improved Means for Paying Out Wire from Wire Coils and for
Controlling the Length of Wire Paid Out.
I, SAMUEL WILLIAM JOHNSON, of 1 Oxford Place, Clifton Road, Aston,
Warwickshire, Engineer and Machinist, 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 :-
This invention consists of the herein described improved means for paying out wire
from wire coils and for controlling the length of wire which has been paid out
my invention being applicable for use with machines for forming small wire coils
or springs for mattresses and for other purposes from a large wire coil and with
machines for winding wire on to bobbins of wire netting machines and for use with
other machines in which wire is operated upon. By my invention the wire as it is
unwound from the long coil (which latter is stationary) turns an arm which gives
motion to gearing which latter in turn operates a tappet which when it has reached
a certain predetermined position corresponding with the required length of wire
which has been paid out from the coil releases or operates the strap fork bar or
clutch bar or other device for stopping the wire coiling or other machine with which
my invention is used thus bringing the machine to rest and causing the wire coil
or wire spring to be made exactly the length required.
My invention is illustrated by the accompanying drawings on which Fig. 1 is a
front view of an apparatus constructed according to this invention for paying out
wire from wire coils and for controlling the length of the wire paid out. Fig. 2 is
a side view of the said apparatus; Fig. 3 is a plan of the same and Fig. 4 is a
sectional plan of the same.
The same letters of reference indicate the same parts in all the figures of the
drawings.
According to one arrangement of my invention I provide a circular or other
base A of a size to take the large coil B of wire which is to be used up in the
machine this said wire coil lying on the base in a horizontal position. The base A
is by preference made with a central circular portion a¹ standing up therefrom so
as the better to keep the wire coil B in position. Standing up from the centre

page_text: of the base A and fixed on the stand L hereinafter described there is a
stationary axis C carrying the arm D and about which the arm is revolved
by the wire b¹ as it is paid out; this wire b¹ passing through a hole e¹ in the
guide E carried by the arm D and then once round the roller F which is free
to revolve at the outer end of the arm D and is fixed on the shaft G herein-
after referred to. The wire then passes over the guide pulley h¹ carried by the
arm D and then along to the top of the centre axis C where the wire passes through
an eye or under another guide roller I also carried by the arm D and up and over
another guide roller I supported by any convenient means and then on away to the
machine by which the wire is made into coils or otherwise used up, so that as the
wire is drawn from the coil B the arm D will thereby be caused to revolve.
Mounted upon the shaft G (which latter is carried by the arm D and is free to
revolve in bearings one of which is marked g' and the other is formed in the
sleeve or boss part of the arm which turns upon the shaft C) there is a small
pinion J which gears with a stationary toothed wheel ring K supported from the
stationary centre axis C by any convenient means as by the bracket arms k¹ k³ k³.
Upon the same shaft G there is fixed another toothed pinion M which can be moved
to and fro along the shaft and fixed in any desired position so as to gear with one
or other of the annular sets of holes n (or instead of holes there may be pegs teeth
or other like devices) arranged in the face wheel N which is free to revolve about
the central axis C. Fixed to the boss of this face wheel N and underneath the
same there is a tappet O arranged to act upon the arm P which is fixed to the
clutch bar P (or to the strap fork bar or other moving bar) for stopping the
machine which is using up the wire paid out from the coil, so that when this
tappet O comes into contact with the upwardly projecting arm P the latter is by
the tappet O moved outwardly off the notch g' in the guide Q so that the spring p¹
connecting the arm P to a fixed point of the stand L will then move the clutch
bar P' in the direction indicated by the arrow in Fig. 1 and throw out the clutch,
or move the driving band on to the loose pulley, or otherwise stop the said machine
or the bobbin which is using up the wire when the required length of wire has been
unwound from the large coil B.. The connection of the clutch bar P¹ to the clutch
of the machine or bobbin which is using up the wire may be arranged in various
ways as may be most convenient according to circumstances. I have shewn on my
drawings a convenient arrangement of connections where my invention is employed
with a machine for making wire coils for coiled wire mattresses. In this case the
clutch bar P is connected to the upper end of the upright lever p² mounted on the
way shaft p³ on which is also the upright lever p₁ and this is jointed at to the two
armed lever p turning on the fulcrum p' and connected to the clutch p of the
machine so that when this clutch p8 is thrown out of gear with the other part of
the clutch p which is fixed on the driving shaft p this driving shaft of the wire
coiling machine will cease to revolve. p is a handle arm fixed to the lever p' for
stopping and starting the wire coiling machine.
In order to regulate and predetermine what length of wire shall be paid out
from the coil B by my apparatus before the tappet O strikes the arm P and stops
the machine which is using up the wire paid out, the pinion M has to be moved
along the shaft G and fixed thereon so as to gear with the particular circle of
holes n in the face wheel N (or with the teeth pegs or other devices on the face
wheel when the same are used instead of the holes n) which will cause the face
wheel N to have turned through such an angle as to release the clutch fork arm P
and stop the machine which is using up the wire when the proper length of wire has
been paid out from the coil B round the pulley F. On my drawing (Fig. 3) the
pinion M is represented as gearing with the third row of holes n counting in from
the periphery; this will cause the face wheel N to revolve at a certain speed and
the machine which is using up the wire to stop when the arm D has made a certain
number of revolutions and a certain length of wire has been paid out.
If the
machine is required to stop when a shorter length of wire has been paid out then
the pinion M has to be moved and fixed nearer to the centre axis C to gear with

page_text: a smaller circle of holes n and make the face wheel N revolve faster but if the
machine is required to stop when a longer length of wire has been paid out then the
pinion M has to be moved along the shaft G and fixed to gear with a larger circle
of the holes n nearer to the periphery of the face wheel N and make the latter
revolve slower. The slots n' n² n³ in the face wheel N are to enable the pinion M
to be moved along the same nearer to or farther from the centre C as may be
required, without lifting the pinion M out of gear with the face wheel N.
It is to be understood that the friction of the wire 6' passing round the pulley F as it
is paid out causes this pulley and the shaft G with its pinions J and M to revolve
about the axis of the shaft G so that the pinion J gearing with the fixed toothed
ring K causes the arm D and parts carried thereby to turn round centre axis C as
the wire is paid out and at the same time the pinion M turns the face wheel N and
tappet faster or slower and releases the clutch bar arm P when the proper
length of wire has been paid out as stated above. Thus the arrangement of the
spur pinion J toothed ring K pinion M and face wheel N together with the shaft C
adapted to revolve about its axis and to roll round the stationary toothed ring K
form an arrangement of differential gearing by which as stated above the facc
wheel N can be caused to revolve either faster or slower than the arm D and shaft G
according to the length of wire which is to be paid out before the machine using
up the same is stopped. The act of throwing into gear the clutch p8 (or moving
the driving band from the loose on to the fast pulley of the machine using up
the wire) to start the machine using up the wire moves the clutch bar or strap fork
bar Pand its arm P to the position shewn by my drawings engaging with the
notch q' ready to be released by the tappet O as above described.
It will be evident that it is necessary that the face wheel N should be stopped
immediately the clutch bar arm P is released by the tappet Oso as to always start
from the same point. In order to effect this I provide (see Figs. 1 and 4) the two
armed catch piece R one arm of which lies across the path of the arm Pas shewn
and the other arm is made hooked as shewn so that immediately the arm P is
released by the tappet O the arm P acts upon the catch R and turns it to the
position shewn by the dotted lines in Fig. 4 so that the peg or projections s fixed on
the centre boss n² of the face wheel N will immediately come into contact with the
projecting end of the arm r³ which latter will thus form a stop and prevent the face
wheel N and the arm D revolving any further round the central axis C.
The base A may be fixed so as to always remain stationary, but in order to take
up any slack there may be in the wire it is convenient to make the base A so that
it can if required be turned round for this purpose. I therefore prefer to mount the
base A on the rollers T carried by bearings t¹ on the top of the stand L above
referred to. The other rollers U also carried by bearings ul on the stand L take
against the inside of the circular part a¹ of the base A and thus keep the base A
central with the spindle C. As before stated the base A remains stationary whilst
the wire is being paid out from the coil B.
The accompanying drawings shew what I consider to be the best way of carrying
my said invention into practice but it is to be understood that my said invention is
not limited to the precise details shewn.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-

of wire paid out, the combination of an arm mounted to revolve round the wire
coil from which the wire is to be paid out, a shaft carried by said arm and having
on its outer end a pulley round which the wire is coiled so as to turn the shaft
axially by the wire as it is paid out, a guide and guide rollers to lead the wire on
to said pulley on the shaft and from the same to the centre of the coil, differential
gearing arranged to transmit the rotary motion of the said shaft about its axis and
round the wire coil to a revolving tappet which, when it reaches a certain position

page_text: and the proper length of wire has been paid out, releases or otherwise moves the
strap fork bar or clutch bar or other part which stops the machine or bobbin or
other appliance which is taking the said wire from the said coil, all substantially as
herein before set forth.
