Improvements in Wire Nail Making Machines.
We, FELIX HADLEY & COMPANY LIMITED, and THOMAS CLARKE, of the
Firm of Felix Hadley & Co. Ld. both of The Nail Works, Eyre Street, Spring
Hill, in the City of Birmingham, Nail Makers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to the manner in which we construct and arrange machines
for the manufacture of twisted wire nails; or parts of machines for the manufacture
of the same for attachment to existing ordinary wire nail making machines.
In carrying our invention into effect we attach to or form upon an ordinary feed
slide of a wire nail making machine, a hollow stud or former, the stud being in
effect a spiral screw or fixed spindle which is to form the copy to give the desired
twist to the wire nail. We attach this hollow stud to the slide in such a manner that
while the slide travels forward it works into a nut or screwed socket which we
carry upon another frame head, or mount in position near to the same; this nut or
socket being screwed at one end to receive a fixed screw spindle and having at the
other end a cap or plug with a hole through the centre of any suitable section and
of a size suitable for retaining the wire in position. We hold the nut by means
of split clamping plates or by collars with a cap between, so that the nut may
revolve when the screw is forced forward and backward by the feed slide, but while
revolving shall remain in a fixed position relatively to the frame head of the
machine. To reduce friction we sometimes provide roller or ball bearings for the
nut to revolve within, these being of any usual or ordinary construction.. We
prefer to form the screwed socket with a bush or plug having a thread within it,
which bush can be removed when worn, or when it is desired to produce a shorter
or coarser pitch nail. Similarly the end cap or plug for retaining the wire we
prefer to make removable to suit different sizes and sections of wire.
In producing a twisted wire nail from ordinary wire, we cause the wire to pass
through the ordinary feed slide and to be carried forward by the usual ordinary
mechanism the wire passing right through the fixed hollow screw and through the
end cap of the nut socket until it is received by the dies in the machine. With
the advance of the wire and its feed slide the screwed spindle travelling with it
causes the socket to revolve; and when the wire is cut off by the dies and the
feed slide is withdrawn by the ordinary mechanism, the socket is again caused to
rotate, and as the wire is held between the dies at one end (which dies may be
either round or square) and in the end cap of the socket at the other end, a twisting
motion is given to the wire corresponding to the thread formed upon the spindle
which is travelling backwards.
The ordinary cutting off, pointing and heading mechanism we employ without
alteration, and we construct the framework of the machine in the usual ordinary
manner slightly modified to receive our revolving socket and the travelling spiral
spindle.

Improvements in Wire Nail Making Machines.
We, FELIX HADLEY & COMPANY LIMITED, and THOMAS CLARKE, of the
Firm of Felix Hadley & Co. Ld. both of The Nail Works, Eyre Street, Spring
Hill, in the City of Birmingham, Nail Makers, 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 relates to the manner in which we construct and arrange machines
for the manufacture of twisted wire nails; or parts of machines for the manufacture
of the same for attachment to existing ordinary wire nail making machines.
Referring to the accompanying sheets of explanatory drawings-
Figure 1 illustrates in part plan a wire nail making machine having our
improvements arranged thereon; while Figure 2 represents in plan a modified
arrangement, and Figure 3 a front sectional elevation upon the line y (Figure 2).
In carrying our invention into effect in one manner we attach to or form upon
an ordinary feed slide B of a wire nail making machine, a hollow stud or former A,
the stud being in effect a spiral screw or fixed spindle which is to form the copy to
give the desired twist to the wire nail. We attach this hollow stud or former A
to the slide B in such a manner that while the slide B travels forward it works into
a nut or screwed socket C which we carry upon another frame head D, or mount
in position near to the same; this nut or socket being screwed at one end C₁ to
receive the fixed screw spindle A and having at the other end a cap or plug E
with a hole through the centre of any suitable section and of a size suitable for
retaining the wire in position. We may hold the nut or screwed socket C by
means of split clamping plates or by collars with a cap between, so that the nut
may revolve when the screw A is forced forward and backward by the feed slide,
actuated from the main shaft or spindle of the machine; but while revolving shall
remain in a fixed position relatively to the frame head of the machine. To reduce
friction we sometimes provide roller or ball bearings for the nut to revolve within,
these being of any usual or ordinary construction. We sometimes prefer to form
the screwed socket C with a bush or plug C¹ having a thread within it, which bush
can be removed when worn or when it is desired to produce a shorter or coarser
pitch nail. Similarly the end cap or plug E for retaining the wire we prefer to
make removable to suit different sizes and sections of wire.
In producing a twisted wire nail from ordinary wire, we cause the wire to pass
through the ordinary feed slide B and to be carried forward by the usual ordinary
mechanism the wire passing right through the fixed hollow screw A and through
the end cap E of the nut socket C until it is received by the dies G in the machine.
With the advance of the wire and its feed slide B the screwed spindle A travelling
with it causes the socket C to revolve; and when the wire is cut off by the dies
and the feed slide is withdrawn by the ordinary mechanism, the socket C is again
caused to rotate, and as the wire is held between the dies G at one end (which dies
may be either round or square) and in the end cap E of the socket C at the other
end, a twisting motion is given to the wire corresponding to the thread formed upon
the spindle which is travelling backwards.
It is obvious that instead of producing the necessary motion of rotation of the
screw socket C by means of the introduction of the screwed spindle therein, we
may, without departing from the essential features of our invention arrange that
the screwed spindle be securely fixed within a socket such as C and that a horizontal
travelling screwed nut or socket be employed for producing this motion.
Figures 2 and 3 illustrate such an equivalent arrangement carried into effect
upou a wire nail making machine, the screwed spindle A being upon the one end
fixed within a socket C and the other end supported upon a bracket I secured to
the machine frame, while a screwed nut or socket J is caused to travel backwards

page_text: and forwards upon the spindle and the necessary motion produced by means of the
slide B actuated from the shaft or spindle of the machine. As illustrated the
feeding slide B is attached by bolts and nuts K K' to the travelling nut or socket J
and so is actuated with it from the shaft or spindle of the machine.
The ordinary cutting off, pointing and heading mechanism we employ without
alteration, and we construct the framework of the machine in the usual ordinary
manner slightly modified to receive our revolving socket and the travelling spiral
spindle.
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:
1. In a wire nail making machine, the combination and arrangement of a screwed
spiral or twisted former or spindle such as A and a nut or socket such as C
and J substantially as and for the purposes hereinbefore described and as illustrated
in the accompanying drawings.
2. In a wire nail making machine, the application and arrangement of a copying
spindle or plug for enabling a twisted wire nail to be produced, substantially as
hereinbefore described.
3. In a wire nail making machine, the construction and arrangement of a nut or
socket such as C or J for producing a twisted wire nail substantially as hereinbefore
described and as illustrated in the accompanying drawings.
