Improvements in Slugging or Nailing Machines.
I, DANIEL ARTHUR BERRY, of 20, Stockley Street, Northampton, in the County
of Northampton, Boot and Shoe Manufacturer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in slugging or nailing machines and
has for its object, firstly, to dispense with the movable portion of the head
whereby hitherto the feeding of the work has been effected and employ in lieu
thereof in a suitable position a feed wheel, secondly, to dispense with the neces-
sity of dropping the horn or work support whilst the machine is working
thereby rendering the machine much simpler and thus less liable to repairs and
enabling same to be run at a much greater speed and more silently than hitherto
has been the case, and, lastly, to provide means whereby two or more slugs or
nails can be driven of equal or different length simultaneously or alternately.
To this end I build a machine having an entirely stationary head in which
I form two or more vertically inclined grooves in each of which I employ a
gripper formed in two parts diagonally hinged together.
The wire from which the slugs or nails are cut passes between the said
grippers and is fed thereby into two throats arranged below the head of the
machine.
The said throats are superposed and a saw is adapted to work between the
same to cut slugs or nails from the respective ends of the wires. The said saw
is caused to move against the wires when cutting off slugs or nails and to
recede to allow of driving in the slugs or nails cut off and of feeding the wires
into the lower throat again. The lower throat is stationary and the upper throat
rendered movable so as to allow of uncovering the slugs or nails cut off in
the lower throat and to give access to the plungers which drive the same in
to the work and also for forming the holes for the successive slugs or nails if
required.
The said plungers are arranged to slide vertically in the head of the machine
and are depressed by an eccentric stud or studs and raised to its normal position
by a spring.
The wire grippers are vertically depressed by means of abutment screws
carried by a cross piece suitably reciprocated and raised again to their normal
position by springs.
The said screws are rendered adjustable relative to the normal position of
the said grippers, which permits of varying the down movement of the grippers
and thus the length of the slugs or nails to be cut at will.
One side of each gripper has teeth or notches and on the head of the machine
a spring bolt is employed by means of which any of the grippers can be retained
out of contact with the respective abutment screw and thus rendered inoperative
when desired.
It will thus be readily understood that by the arrangement of the wire
grippers and spring bolts described, one or more slugs or nails of equal or of

page_text: different length may be cut off and driven in to the work at one time, or alter-
nately, without stopping the machine, whilst one slug or nail may be used as a
fastening and the other simply as a wearing surface or for ornamental purposes.
The horn or work support I employ, is hinged to a foot lever supported by a
spring and rendered laterally movable in its upper bearing so as to permit of
bringing it nearer to and further away from the head of the machine to suit
the work to be slugged or nailed.
The said foot lever serves to depress the horn or work support and to allow
of placing the work upon the same, whilst when the machine is running, the
horn or work support is retained vertically in position by a suitable locking
device, say by a clamp formed in two parts hinged together and placed around
the shaft of the horn or work support, the said parts being kept open by a
spring and closed when required to grip the said shaft by a wedge, cam or the
like, operated by hand or foot.
The work to be slugged or nailed is fed on the horn or work support by
being pressed against a feed wheel rotated in a horizontal plane and mounted
below the head of the machine.
In order to permit of working the machine by hand when required, I employ
upon the main shaft a hand wheel which the operator can turn and thus drive
in one or more slugs by hand, the said wheel being adapted to be thrown
automatically out of gear when running the machine by power.
The main driving shaft I may mount in line with the front of the machine
or vertically as may be found most convenient and may be arranged to be
driven altogether by hand, foot or motive power to suit various conditions.

Improvements in Slugging or Nailing Machines.
I, DANIEL ARTHUR BERRY, of 20, Stockley Street, Northampton, in the County
of Northampton, 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*: —
This invention relates to improvements in slugging or nailing machines and
has for its object, firstly, to dispense with the movable portion of the head
whereby hitherto the feeding of the work has been effected and employ in lieu
thereof in a suitable position a feed wheel, secondly, to dispense with the neces-
sity of dropping the horn or work support whilst the machine is working
thereby rendering the machine much simpler and thus less liable to repairs and
enabling same to be run at a much greater speed and more silently than hitherto
has been the case, and, lastly, to provide means whereby two or more slugs or
nails can be driven of equal or different length simultaneously or alternately.
And in order that my invention may be more fully understood I have caused
to be appended hereunto two sheets of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1 & 2, Sheet I, are respectively a side and a front view of my improved
slugging or nailing machine complete.
Figs. 3 & 4, Sheet II, are respectively a front and side elevation partly in
section, and Fig. 5 a vertical section at line A-A of Fig. 4, of the head of the
+

page_text: machine at an enlarged scale. Figs. 6 & 7 are sectional plans at lines B-1
and C-C of Figs. 3 & 4 respectively. Fig. 8 shows diagrams of various patterns
of throats, and Fig. 9 a nail pattern which may be produced by the machine
on heels.
Referring to Fig. 1, I build my improved slugging or nailing machine with
an entirely stationary head a secured to the top of a stand 6 which together
form the framework of the machine.
In the front of the head a I form two or more vertically inclined grooves c
in the present instance two, see more particularly Sheet II, Figs. 3 & 6, in each
of which I employ a gripper & formed in two parts diagonally hinged together
by a link e.
The wire from which the slugs or nails are cut, passes between the said
grippers from above and is fed thereby into two throats gh superposed in the
lower part of the head of the machine and in register with each other when
the feeding of the wire takes place.
Between the said throats, a saw is employed adapted to cut slugs or nails
from the respective wire ends fed into the said throats, which saw is carried
by a slide k reciprocated by a lever 7, connected therewith and actuated by a
cam m secured on the driving shaft n, so that when the slugs or nails require
cutting off, the saw i moves against the wire and recedes after having cut off
the slugs or nails so as to allow of feeding the wires into the throats again.
In the present instance the said saw is rotated by a flexible shaft o actuated
by means of bevel gearing p, q from the driving shaft n.
The lower throat is stationary and the upper throat h rendered movable
in the head a, see Fig. 4, so as to allow of uncovering the slugs or nails cut
off in the lower throat and give access to the plungers r, secured to a bar s
vertically guided in the head of the machine and adapted to form holes in the
work for slugs or nails and to drive the latter into the same.
In the present instance the movable throat his horizontally reciprocated,
that is to say, brought in and out of register with the stationary throat g by
means of a levert the lower end of which engages the back end of the throat h,
and the upper of which is actuated by a cam secured on the driving shaft n.
In some cases the said plungers may be only used for driving in the slugs
or nails and the holes for the slugs or nails formed in the work by awls (not
shown) arranged adjacent.
The said plungers r,s are depressed by an eccentric stud v or studs v & vl
on a disc fixed on the driving shaft and raised to their normal position by
a spring w.
When employing two studs, v serves to drive the slugs or nails into the work
and to depress the plungers still further after the work has been fed, which
take the place of awls and form holes for the slugs or nails.
The wire grippers d are vertically depressed by means of abutment screws r
carried by a cross piece secured to the bar y suitably reciprocated, say depressed
by an eccentric stud z on the driving shaft n and raised again to its normal
position by a spring 1.
The said screws are rendered adjustable relative to the normal position of
the said grippers, which permits of varying the down movement of the grippers
and thus the length of the slugs or nails to be cut, at will whilst the grippers
are raised to their normal position, say by springs attached thereto and to
the head.
One side of each gripper has teeth or notches 2 and on the head of the machine
a spring bolt 3 is employed by means of which any of the grippers can be
retained out of contact with the respective abutment screw and thus rendered
inoperative when desired.
It will thus be readily understood that by the arrangement of the wire
grippers and spring bolts described, one or more slugs or nails of equal or of
different length may be cut off and driven into the work at one time or alter-

page_text: nately without stopping the machine, whilst the longer slug or nail may be
used as a fastening and the shorter simply as a wearing surface or for ornamental
purposes.

The horn or support 4 I employ, see Sheet I, is hinged to a foot lever 5
supported by a spring 6 and rendered laterally movable in its upper bearing,
so as to permit of bringing it nearer to and further away from the head of the
machine to suit the work to be slugged or nailed.
The said foot lever serves to depress the horn or work support and to allow
of placing the work upon the same, whilst when the machine is running, the
horn or work support is retained vertically in position by a suitable locking
device, say by a clamp 7 formed in two parts hinged together and placed around
the shaft 4 of the horn or work support, the said parts being kept open by a
spring and closed when required to grip the said shaft by a wedge, cam or the
like, operated by hand or foot, in the present instance by a screw 8 upon which
is secured a lever 9 connected by a rod 10 to a hand lever 10* fulcrumed to
the stand of the machine.
+ !
The work to be slugged or nailed is fed on the horn or work support by being
pressed against a feed wheel 11 rotated in a horizontal plane and in a cavity 12
formed in the underside of the head a of the machine by means of a friction
pawl 13 adapted to grip the flange 14 formed on the feed wheel 11, see more
particularly Figs. 4 & 7, and reciprocated by means of a rod 15 connected to a
lever 16 actuated by the cam face 17 on the cam u secured to the driving shaft.
In order to permit of working the machine by hand when required I employ
upon the main shaft a hand wheel 18-which the operator can turn and thus
drive in one or more slugs or nails by hand.
. In the present instance the driving shaft is arranged at right angle to the
face of the machine but it is obvious that the same may also be arranged parallel
therewith or in any other suitable position without departing from the nature
of my invention.
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:
1st. In a slugging or nailing machine, the combination with a horn or work
support 4 and a stationary head a, of a feed wheel 11 rotated 'intermittently in
a horizontal plane and adapted to feed the work pressed laterally against it, all
substantially as set forth.
2nd. In a slugging or nailing machine, the combination of a stationary and
a movable throat g, h employed above each other and means for bringing the
'movable throat h in and out of register with the stationary throat g, all sub-
stantially as and for the purpose set forth.
3rd. In a slugging or nailing machine having two throats one above the
other, a rotary saw i employed in a horizontal plane between the said two
throats and adapted to cut off slugs or nails from wire fed into the said throat,
all substantially as set forth.
4th. In a slugging or nailing machine having two throats one above the
other and a rotary saw between the same, means for horizontally reciprocating the
same intermittently once during each operation, all substantially as set forth.
5th. In a slugging or nailing machine having two throats one above the
other, means for feeding one or more wires into the said throats, consisting of
grippers d, each of which is depressably employed in a inclined slot c formed
in the machine head and on its down movement grips and feeds the wire into
the said throat; whilst on its up movement it releases the same, all substantially
as set forth.
6th. In a slugging or nailing machine having two throats one above the
other and grippers for feeding the wire into the said throats, abutment screws a
vertically reciprocated and adapted to depress the said grippers and capable of

page_text: adjustment relative to the said grippers, all substantially as and for the purpose
set forth.
7th. In a slugging or nailing machine having two throats one above the
other, grippers for feeding the wire into the said throats and abutment screws
for depressing the said grippers, spring bolts mounted in the machine head
and adapted to render the said grippers at will inoperative, all substantially as
set forth.
8th. In a slugging or nailing machine, a plunger r, s supported by a spring w
and means for depressing the said plungers intermittently successively, one
depression serving for the formation of holes in the work for the slugs or nails
and the other for driving the slugs or nails in by the said plungers, all
substantially as set forth.
