We, ALFRED EDMUND WALE, of the Firm of T. E. Wale and Sons, of Oozells
Street, Birmingham, in the County of Warwick, Manufacturers, and WILLIAM
POWELL, of 78, King Edward's Road, Birmingham aforesaid, Mechanic, do hereby
declare the nature of our said invention to be as follows: —
"
"coiler"
Our invention has for its object improvements in the tool known as a
or "giraffe" for use in coiling wire or wires for the manufacture of woven wire
mattresses and other woven wire articles and in the manner of using the same in
the manufacture of woven wire. Our present invention is amongst other things
an improvement upon the "giraffe' set forth in our previous Letters Patent
No. 16476 A.D. 1894 granted to T. E. Wale, W. H. Wale, A. E. Wale, and
F. C. Adie, as a communication from White Manufacturing Company, in which
the "giraffe" there claimed is made by placing a number of wires of the desired
pitch on a solid core. These are then covered by an outer casing or sleeve, when
one or more wires are withdrawn, thus leaving a helical space which forms the
guide or die for forcing through the plain wire from the reel so forming spiral
coils for the manufacture of wire mats and other articles. Now our present inven-
tion is an improvement in such tools and is as follows:-
We first take a solid core and cut in it a helical groove of the same depth as
the diameter of the wire and of sufficient width to take in two or more thicknesses
of wire when fed into it by rolls or other means from a reel in the usual manner.
For instance, if we wish to form the "giraffe" as a tool for forming one spiral
coil of wire at a time we generally cut the helical groove sufficiently wide to take
in three wires abreast. We then feed three such wires into the groove and cut
them off, turning down the ends of the outside wires so as to secure them and
then draw out the centre one thus leaving the required helical groove for the
production of single coiled wires. If the tool is required for the production of
two coils at once we cut the helical groove in the core sufficiently wide to receive
four wires from which we withdraw the two centre ones thus leaving the tool
prepared for coiling two wire abreast at one operation and in the same way the
groove in the core may be cut sufficiently wide to receive five, six, or more wires
in which case three, four or more of the centre wires are withdrawn, thus leaving
the required helical groove for the simultaneous production of three, four or
more spiral coils.

page_text: When several coils of wire are formed in the tool at one operation it is found
that from various causes, such for instance as variation in the temper of the wire,
that the several spirals thus produced are not of exactly the same pitch. In order
to equalise them in this respect we fix a small knife or knives upon the core at a
suitable distance from the inouth or exit end of the "giraffe" so as to separate
the two or more wires sufficiently to pass over or under pins which are mounted
upon short ferrules on a reduced part of the core and which are adjustable by
friction or otherwise upon the core so as to strain the wires as they pass along
and confirm them all to one true and accurate pitch.
It has been usual in "giraffes" to use a loose intermediate friction sleeve
between the core and outer sleeve, which is revolved upon its axis by the action
of the wire, so as to avoid grooving the sleeve, but this is sometimes found to
become stationary. To prevent this we form the end with notches and mount a
ratchet lever in such connection therewith and the starting -mechanism-or device,
as to turn the intermediate or inner sleeve one notch each time the machine is
stopped. or started. By these means we produce a "giraffe" having a solid cut
helical groove therein with one or both sides lined with a single wire so as to.
coil one or more wires abreast at one operation in the solid groove having the
single wire liner on one or both sides which are renewable from time to time, the
solid metal at the sides of the groves preventing undue elasticity or spring to
which "giraffes" are liable when the sides of the groove are constituted entirely
by a series of wires. Our invention is equally applicable to "giraffes" in which
the wire is entered from the feed rolls at the angle of the helical groove or on a
line with the axis of the core.

Improvements in the Tool known as a Coiler" or Giraffe "for use
in Coiling Wire or Wires for the Manufacture of Woven Wire
Mattresses and other Woven Wire Articles, and in the manner of
using the same in the Manufacture of Woven Wire.
I, ALFRED EDMUND WALE, of the Firm of T. E. Wale and Sons, of Oozell's
Street, Birmingham, in the County of Warwick, Manufacturers, and WILLIAM
POWELL, of S. King Edward's Road, Birmingham aforesaid, Mechanic, do hereby
declare the nature of our said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
Our invention has for its object improvements in the tool known as a coiler or
giraffe for use in coiling wire or wires for the manufacture of woven wire mattresses
and other woven wire articles and in the manner of using the same in the manu-
facture of woven wire.
Our present invention is amongst other things an improvement upon the giraffe
set forth in our previous Letters Patent No. 16476 A.D. 1894 granted to
T. E. Wale, W. H. Wale, A. E. Wale, and F. C. Adie, as a communication from
White Manufacturing Co. in which the "giraffe" there claimed is made by placing

page_text: *
a number of wires of the desired pitch on a solid core, these are then covered by
an outer casing or sleeve, when one or more wires are withdrawn thus leaving
a helical space which forms the guide or die for forcing through the plain wire
from the reel so forming spiral coils for the manufacture of wire mats and other
articles. Now our present invention is an improvement in such tools and is as
follows:
We first take a solid core and cut in it a straight groove terminating in a helical
groove, of the same depth as the diameter of the wire and of sufficient width to
take in two or more thicknesses of wire when fed into it by rolls or other means
from a reel in the usual manner. For instance if we wish to construct the
giraffe" as a tool for forming one spiral coil of wire at a time we generally
cut the helical groove sufficiently wide to take in three wires abreast. We then
feed three such wires into the groove and cut them off turning down the ends of
the outside wires so as to secure them and then draw out the centre one thus
leaving the required helical groove for the production of single coiled wires. If
the tool is required for the production of two coils at once we cut the helical
groove in the core sufficiently wide to receive four wires from which we withdraw
the two centre ones thus leaving the tool prepared for coiling two wires abreast
at one operation, and in the same way the groove in the core may be cut
sufficiently wide to receive five six or more wires in which case three, four, or
more of the centre wires are withdrawn thus leaving the required helical groove
for the simultaneous production of three, four or more spiral coils.
In order that our invention may be more clearly understood and easily carried
into practical effect we have appended hereunto four double sized sheets of drawings
upon which we have shewn several examples of our coiler or giraffe.

Figures 7, 8 and 9 are detail views of some of the various parts which form the
coiler or "giraffe."
Figure 10 represents another form of our coiler, or giraffe for forming three
helical coils at one operation.
Figure 11 is a longitudinal section of Figure 10.
Figures 12 and 13 are views of the fast and loose sleeves as shewn at Figures 10
and 11.
Figure 14 is a view of a portion of the knife detached.
Figure 15 represents a coiler or giraffe for coiling three wires fed in from the
side.
Figure 16 is a part sectional view shewing the core formed in two parts.
Figure 17 represents a coiler or giraffe with stationary knives and pegs on
movable ferrules.
In carrying our invention into practice we first take a solid core B having the
flange extending around a portion of one end and in 'this end we drill a hole,
longitudinally down the centre extending a portion of its length, we then cut
through this core the groove 63 which is formed helical towards the hollow end.
This groove is of the same depth as the diameter of the wire and of sufficient
width to take in three wires. We now fit into the hollow end of the core B the
solid core.D with its loose sleeve which extends beyond the core B the outer end
of this sleeve butts against the collar which is formed solid with the core and
this solid core D is held in the core B by the cross pin 69 or by other means. The
collar d which butts.against the collar is next fitted onto the core and the outer
face of this collar is cut at about the same angle as the pitch of the coil. The
movable knife K which equalizes the helices of the coils of the wires as they 'pass

page_text: through is now fitted onto the solid core butting against the collar №³ so that it is
placed at the same angle as the outer face of this collar. The collar dis next
fitted onto the solid core, the inner face which butts against the knife being cut
at the same angle as the outer face of the collar d³ then the collar is fitted onto
the core and lastly the nut or screwed collar ( which firmly holds all the parts
together is screwed on to the end of the core which is screw threaded for that
purpose. When these parts have been fitted together the core B is fitted into the
outer sleeves A and A¹ which keep the wires in position as they are fed into the
groove 6. The sleeve A¹ which butts against the flange b' is free to revolve and
is milled or serrated on its outer surface, so as to enable the operator to readily
ascertain when it is revolving, but the sleeve A is fixed to the core B by the cross
pin a as clearly shewn at Figure 3. The inner sleeve is also free to revolve.
After the three wires have been fed into the groove the required, distance, they
are cut off and the ends 10 and 7 of the outside wires W and We turned down
so as to secure them as clearly shewn at Figures land 2. We then draw out the
centre wire leaving the required helical groove lined on either side with a renew-
able wearing surface for the production of the coiled wire W as shewn. In some
cases the helical groove may be lined on one side only with a renewable wearing
surface.
If the helices of the coil should vary in pitch they can be equalized by the
knife K which if moved on its axis in the reverse direction to which the coil
advances opens out or forces the coils further apart thus increasing the pitch of
the helices and correspondingly if moved in the same direction as the coil advances
would decrease the pitch. This being accomplished by the pressure of the knife
against either the back or front of the wire respectively. By having the outer
sleeve A¹ and the inner sleeve fitted loosely they are prevented from being
unevenly worn by the friction of the wire as it passes through the helical groove
as such friction causes them to revolve.
At Figures 10 and 11 we have shewn a modification in the method of constructing
our coiler or giraffe. In this case, we form the core B in which the helical
groove is cut solid with the core D the part which forms the core D being
reduced in diameter and onto this reduced part we fit the various loose collars and
the knives K K and K the whole of these parts being locked in position on this
core by the end ferrule. Or the portion of the core B in which the helical groove
is cut may be made separate from the other portion and then drilled and tapped to
receive the screwed end of the other portion as shewn at Figure 16. We then fit
the loose sleeve E over the helical portion of the groove the flange e¹ of which
butts against the peg e³ fixed in the core B. The outer sleeve A³ is now fitted
over the other portion of the core B and over a portion of the sleeve E the end
being recessed for that purpose and this outer sleeve is fixed to the core B by the
screw pin a'. When the parts have been fitted together as shewn at Figures 10
and 11 five wires are fed the required distance into the groove 63 and cut off, the
ends of the two outside wires are next turned down as previously explained and
then the three centre wires withdrawn thus leaving sufficient space in the groove
between the two outside wires to form three helical coils simultaneously. The
helices of the leading coil would be equalized by the movable knife K those of
the next coil by the movable knife K¹ and the helices of the last coil by the movable
knife K by the operator moving the knives either backwards or forwards which
is accomplished by turning either one of them around upon its axis D. In a like
manner when the coiler or giraffe is made to produce more than three helical coils
simultaneously we increase the number of knives to correspond to the number
of such coils as a distinct knife is generally required to adjust each coil. It will
also be evident that the giraffe as shewn at Figures 1 and 2 may be formed so as
to produce two, or more than two helical coils simultaneously, the helical groove b
being enlarged so as to accommodate two wires more than the number of helical
coils produced.

page_text: '
At Figure 15 we have shewn a coiler or giraffe provided with an arrangement
in which the wires are fed into the giraffe at the angle of the helical groove instead
of in a line with the core and thus we accomplish by fixing the guide F by means
of the bracket F1 to the outer sleeve A the wires which are fed by rolls or other
means from a reel into this guide F, enter the helical groove through an opening
formed in the side of the sleeve A and pass cut of this groove in a similar manner
as previously described. It will be evident that this arrangement of feeding the
wires into the side of the coiler or giraffe may be used with the various forms of
the coilers or giraffes instead of the direct feed as shewn.
Figure 17 represents one of our coilers or giraffes in plan view provided with
stationary instead if movable knives. In this case we fix the knives and upon
the core near the mouth or exit end of the giraffe in such a position that as the
three wires pass out of the helical groove they are separated by these knives
sufficiently to pass over or under the pins p¹ and p³ which are fixed in the short
ferrules or sleeves and f³ mounted on the reduced part of the core. As the
leading wire w³ issues from the mouth of the giraffe it passes in front of the knife k³
and in front of the peg p¹ and also in front of the peg 23, the second wire w
passes between the knives and in front of the peg so that if the helices of this
wire should by any cause differ in pitch from the leading wire this peg and ferrule
can be turned to equal the leading wire round upon the core until the pitch is
sufficiently elongated. The third wire w as it issues from the mouth of the giraffe
passes behind the knife and behind the peg p¹ but in front of the peg 2 which
together with its ferrule is then revolved until the third coil is elongated to the
same pitch as the other two helices.
"
By these means we produce a giraffe" with a helical groove cut out of the
solid metal having one or both sides lined with a single wire so as to coil one or
more wires abreast at one operation in the solid groove having the single wire
liner on one or both sides which are renewable from time to time the solid metal
at the sides of the grooves preventing undue elasticity or spring to which "giraffes"
are liable when the sides of the groove are constituted entirely by a series of wires.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
