PROVISIONAL SPECIFICATION.
Improvements in or applicable to Nail Cutting and Driving
Machines.
I JONATHAN BOOTHMAN of 3 Oak Villa, Brideoak Street, Cheetham near
Manchester, Boot and Shoe Manufacturer, do hereby declare the nature of this
invention to be as follows:-
My said invention relates to improvements in machines for forming nails by
cutting them from a length of wire and subsequently driving them into boot soles
and other articles.
According to my said invention I use a reciprocating cutter bar working in suit-
able guides and carrying a cutter to work in combination with a fixed cutter bar.
The adjacent faces of the reciprocating and the fixed cutters are inclined to give the
required taper to the point of the nail. In the reciprocating cutter I form a recess
passage or clearance of sufficient length to allow the reciprocating cutter bar the
necessary travel. One edge of the said recess forms the point of the nail when
passing the fixed cutter. The lower edge of the fixed cutter severs the nail from the
length of wire.
The throat or nozzle through which the nail is driven (into the boot or other
article) is secured in or to the reciprocating cutter bar and is transferred by the latter
alternately under the driver and under the wire. By such an arrangement as
described nails of different lengths may be cut by simply varying the feed motion of
the wire without changing the cutters.
Guiding grooves are formed for the wire and suitable guides are provided for the
nozzle to work in under the cutter box.
The feed bar or pricker is so arranged as to work simultaneously with the sliding
throat or nozzle.

Improvements in or applicable to Nail Cutting and Driving
Machines.
I JONATHAN BOOTHMAN of 3 Oak Villa, Brideoak Street, Cheetham near
Manchester, Boot and Shoe Manufacturer, 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 :-
My said invention relates to improvements in those machines which form nails by
cutting them from a length of wire and subsequently drive them into boot soles and
other articles.
Such machines are well known and I use the means for feeding the wire driving
the nails supporting and feeding the work being nailed and generally operating the
machine as at present in use and described for instance in the Specification of

page_text: Lake's Patent No. 36 of A.D. 1881 and in the Specification of the Patent of myself
and others No. 155 of A.D. 1895.
My present invention is limited in its scope to improvements in the construction
and mode of operation of the cutters and the throat or nozzle through which the
nails are driven into the work.
According to my present invention I use a reciprocating cutter or cutters working
in combination with a fixed cutter and a reciprocating throat or nozzle.
In order that my said invention may be more clearly understood I will describe
it with reference to the accompanying drawings in which only so much of a nail
making and driving machine is shown as is necessary to explain the construction and
method of using my said invention.

operating the sliding cutters to be herein-
The driver head works in the usual guiding groove 1. The point of the driver
passes through the driving hole 2. The wire is fed down the wire feed hole 3.
The cutting devices work in a fixed cutter box 4 secured to the lower part 5 of the
machine frame.
A fixed cutter 6 the lower part of which is doubly tapered to the shape of the
nail point to be produced is secured by set screws 6ª 6". The wire w is fed down
close to the inner face of the fixed cutter 6. Instead of a vertical fixed cutter as
shown a horizontal fixed cutter having a taper profile may be used. In such case
the fixed cutter is inserted through the recess 7 of the sliding cutter holder 7ª as
indicated by dotted line at 6 in Fig. 2. The reciprocating cutter 7 is preferably
formed in two parts for convenience of grinding the faces of the recess which
corresponds to the point of the fixed cutter. The two parts are secured in the
cutter holder 7 by set screws 10. Instead of forming the reciprocating cutter 7 in
two pieces it may be formed from a single bar with a vee shaped recess or passage
formed therein of sufficient length to allow the necessary travel past the fixed
cutter. The throat or nozzle 8 (through which the nails emerge) is scrowed into a
slide bar 8 which has a reciprocating motion independent of the cutter holder 7ª.
is the waste hole through which the waste cuttings pass. The reciprocating cutter
holder 7 is connected by a link 7b to the fore end of the lever 7°. The slide bar 8*
which carries the nozzle 8 is connected by a link 8b to the fore end of the lever 8°.
The rear ends of the levers 7 and 8 are provided with bowls which take against
the faces of cams D mounted on and secured by set screws to the main driving
shaft E and rotating therewith (see Fig. 5). The curves of these cams are such as
to give an impulse to each lever at each rotation of the driving shaft E.
The cams
are set at such angles to each other as will operate the levers 7 and 8º in the proper
succession as will be well understood after the following explanation of the sequence
of operations of the cutters.
Assuming the parts to be in the position shown in Fig. 1 and the wire to have
'been threaded right through the nozzle the cutter holder 7 is slid to the left by the
lever 7° whereupon the lower end of the wire is severed by the joint action of the
cutters 6 and 7. The travel of the cutter holder 7 is such as to bring the hole 7d
under the driver hole 2. In Fig. 1A the dotted lines show the shape imparted to the
severed length of wire which is held by the nozzle. The under edges of the
reciprocating cutters 7 passing over the severed piece remove the fins wo¹² (Fig. 14)
and push them over the waste hole 9. Thus a flat head is formed on the severed
piece.
The slide bar 8ª is now slid to the right by the lever 8°.

page_text: The travel of the slide bar 8ª to the right is such as to bring the orifice in the
nozzle in line with the passages 2 and 7d which then form a continuous passage for
the descent of the driving pin. When this position is attained the driving pin
descends and the nail is driven through the nozzle.
The fore ends of the levers 7 and 8 now diverge the wire is fed downwards and
the same sequence of operations takes place. It will be understood that after the
first piece of wire has been severed each succeeding piece or nail will have a.
vee point corresponding in shape to the inclined faces of the cutters.
The great advantage of a sliding nozzle such as described is that in order to
produce nails of different lengths it is simply necessary to vary the rotation of the
feed rolls each time the wire is fed forward so as to push the desired length through
the nozzle which is always directly under the wire when it is fed downwards..
Thus no change of cutters is needed for different lengths of nails as is the case with
cutters as hitherto constructed.
The feed bar or pricker for pushing forward the work is timed to work simul-
taneously with the nozzle as will be well understood without further description.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. The hereinbefore described improvements in nail cutting and driving machines.

2. In a nail making and driving machine the combination with a fixed cutter
having a taper profile at the lower end of a reciprocating cutter or cutters having
a correspondingly tapered recess or faces substantially as and for the purpose set.

3. In a nail making and driving machine the combination with the cutting
apparatus of a sliding nozzle substantially as and for the purpose set forth and shown..
4. In a nail making and driving machine the combination of the fixed cutter 6

nozzle 8 the two levers 7° 8° and the cams D substantially as and for the purpose set
forth and shown.
