Improvements in or Applicable to Nail Cutting and Driving
Machines.
I JONATILAN BOOTHMAN of 361 St. Luke's Terrace, 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 or applicable to machines for
forming nails from a continuous length of wire and driving them into boots and
other objects such as described for instance in my prior Patent Specification
No. 13202 of A.D. 1895.
The object of one part of my said invention is to enable the pointed nails to
be driven into say a boot sole with the edge of the inclined point normal to the
edge of the boot sole instead of parallel thereto as has hitherto been the case and
thus among other advantages to prevent the outward deflection of the nails which
sometimes happen when a nail is being driven with the incline of the point parallel
the edge of the article into which it is driven. According to one form of this
part of my said invention the sliding nozzle or carrier through which the nails
pass and which transports the cut nails from the place where they are formed to
the driver is so mounted and operated as to describe a curvilinear path from one
place to the other, Such curvilinear motion of the nozzle holding the nail causes
the latter to rotate through an angle of ninety degrees and thus presents the nails
to the driver at right angles to the wire from which they are cut.
According to another form of this part of my said invention the nail carrier
has a rectilinear reciprocating motion while the sliding cutter has a rectilinear
reciprocating motion at right angles thereto, that is to say to and from the front of
the machine instead of from left to right and vice versa as has hitherto been the
case. In this construction the nail is at once formed with its penetrating edge
normal to the edge of the article into which it is to be driven and no rotation is
necessary.
By the said means flat taper pointed nails may be cut from flat wire with the
inclines on the broad sides of the wire while at the same time enabling them to
be driven with the narrow sides of the nails parallel to the edge of the article
operated upon:
Another part of my said invention relates to the gauge or support under the cutters
and against which the article being nailed is held. The position of this gauge
determines the distance from the edge of the article at which the nails enter.
According to this part of my said invention the gauge is formed with a bar having
a rack or racks or other equivalent indentations or stops with which engage a
detent or detents to prevent the gauge heing pushed back when the work is pressed
against it. The detents are formed as levers or as pins and their engagement. with
the gauge bar-may be.aided by means of springs. In, one form of this part of my
said invention a spring continually presses or pulls the bar backwards and. the

page_text: detents engage alternately with the bar so that when one is released the bar slides
back automatically until restrained by the other detent.

Improvements in or Applicable to Nail Outting and Driving
Machines.
I. JONATHAN BOOTHMAN of 361 St. Luke's Terrace, 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 or applicable to machines for
forming nails from a continuous length of wire and driving them into boots and
other articles such as described for instance in my prior Patent Specification
No. 13202 of A.D. 1895.
The object of one part of my said invention is to enable the pointed nails to be
driven into say a boot sole with the edge of the inclined point normal to the edge
of the boot sole instead' of parallel thereto as has hitherto been the case and thus
among other advantages to prevent the outward deflection of the nails which
sometimes happens when a nail is being driven with the incline of the point
parallel to the edge of the article into which it is driven.
Another part of my said invention relates to the gauge or support under the
cutters and against which the article being nailed is held. The position of this
gauge determines the distance from the edge of the article at which the nails
enter.
In order that my said invention may be more clearly understood I will describe
the same with reference to the accompanying drawings in which
Fig. 1 is a front elevation of the lower part of a nail making and driving
machine showing the wire in position to be cut.
Fig. 2 is a sectional plan through
of Fig. 1.
Fig. 3 is a front elevation corresponding to Fig. 1 but showing the parts in their
relative positions when the nail is being driven.
Fig. 4 is a sectional plan through
of Fig. 3.
Fig. 5 is a transverse section through y-y of Fig. 1.
Figs. 6 and 7 show plan and elevation respectively of the cutters and nozzle or
nail carrier to be hereinafter described.
Figs. 8 and 9 show front and side elevation of a nail having the inclined point
formed on the broad side of the wire.
Fig. 10 is a side elevation of the gauge or support against which the article
being nailed is held.
In the drawings only so much of a machine is shown as is necessary to illustrate
the application of mv said invention. Nail cutting and driving machines having
reciprocating cutters of several kinds operated by horizontal levers actuated by
cams on the driving shaft of the machine are well known.
The driver head works in the usual guiding groove 1. The point of the driver 2
passes through the driving hole 3.
A fixed cutter 4 having an inclined cutting edge at 4° (see Fig. 7 for detail) is
secured by set screws 5 in the frame 6 of the machine. The wire w is fed down

page_text: behind the inner face of the fixed outter 4 and in front of the inclined edge. of
the reciprocating cutter 8 as shown in Figs. 6 and 7. The reciprocating cutter 8
is secured to the cutter holder 8" by means of set screws 8b.
A nozzle or nail carrier 7 through which the Lails pass and which transports
the out nails from the place where they are formed to the driver is mounted in the
slide bar 7 which has a rectilinear reciprocating motion parallel to the front.of
the machine while the sliding cutter 8 has a rectilinear reciprocating motion at
right angles thereto that is to say to and from the front of the machine instead
of from left to right and vice versa as has hitherto been the case. The nail is thus
at once formed with its penetrating edge normal to the edge of the article into
which it is to be driven. When the nail has been cut the waste piece 14 of the
wire is carried forward in front of the reciprocating cutter 8 until reaching the
front edge of the machine it falls into the usual tray or shute conveniently placed
to receive the waste.
་
c is a bracket secured to the frame 6 by means of set screws c' and forms a carrier
or support for the slide bar 7".
Mounted on the table a (Figs. 1 to 4) is an oscillating lever 9 connected at 11
to the slide bar. 7 which when operated by means of a cam on the main driving
shaft imparts a reciprocating motion to the slide 7".
A bell crank lever 10 also mounted on the table a of the machine also worked
by a cam on the main driving shaft operates the reciprocating cutter 8.
Assuming the parts to be in the position shown in Figs. 1 and 2 and the wire
ic have been threaded right through the nozzle or nail carrier 7 the reciprocating
cutter 8 is caused by means of the bell crank lever 10 to travel forward in the
direction of the arrow b (Fig. 2) whereupon the lower end of the wire w is severed
hy the joint action of the fixed cutter 4 and the reciprocating cutter & The lower
end of the wire having been severed remains in the nozzle or nail carrier 7 until
it comes under the driving hole 3 and over the orifice 12 in the stationary nozzle 13
as shown in Figs. 3 and 4 thus forming a continuous passage for the descent of
the driving pin. When this position is attained the driving pin 2 descends and
the nail is driven into the boot or other article.
The slide 7 and the reciprocating cutter 8 next move back into the position
shown in Figs. 1 and 2, the wire is fed downwards, by the usual feed rolls and the
same sequence of operations takes place.
By the said means flat taper pointed nails may be cut from flat wire with the
incline on the broad side of the wire as shown in Figs. 8 an- 9, while at the same
time enabling them to be driven with the narrow sides of the nails parallel to the
edge of the article operated upon.
Another part of my said invention relates to the gauge or support as shown in
Fig. 10. The position of tais gauge determines the distance from the edge of the
article at which the nails enter. According to this part of my said invention the
gauge is formed with a bar 15 sliding in a bracket 16 connected to the frame 6
of the machine. The said har 15 is provided with a rack 17 with which engage
detents 18 and 19 to prevent the gauge bar 15 being pushed back when the work
is pressed against the bowl 20. The detents 18 and 19 are formed as levers and
their engagement with the gauge bar 15 is aided by means of springs 21 and 22.
A spring 23 connected to the underside of the gauge bar continually presses or
pulls the bar backwards and the detents 18 and 19 engage alternately with the
gauge bar 15, so that when one is released the gauge bar 15 slides back auto-
matically until restrained by the other detent. The bowl 20 mounted on the
gauge bar 15 may be adjusted to any height by means of the adjusting screw 24.
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 herein before described improvements in nail cutting and driving
machines substantially as and for the purpose set forth and shown.
