Improvements in Nailing, Sprigging, and Pegging Machines
employed in Boot and Shoe Manufacture.
I, RICHARD WILKINSON BATEMAN of 8 Hanover Street, Halifax, in the
County of York, Shoemaker, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improved means and apparatus for operating the
pricker, for cutting and pointing the nails or sprigs, to an improved sectional bar
from which to cut and form headed sprigs or "fitters," and to operating the
horn," on which the boot or shoe is received and held whilst under operation.
The boot or shoe, being in position on the horn, the pricker is caused to descend
and pierce the sole, for reception of the nail sprig or peg, through the action of a
cam slot, cut in a slide piece, worked by means of a crank pin, received in the slot,
said pricker is then carried forward whilst still in the leather, and moving the
boot with it, by means of a slide piece, operated by cam groove, an arm side
shaft, and a short slotted lever. The pricker is then withdrawn, by means of
the cam slot first mentioned, and the pricker holder or clamp, is drawn back
through the action of a return spring. The nail or sprig, being formed from
a continuous wire as ordinary, and when the nail is cut off, it is received in a slide
piece, which moves forward, and carries the nail, over the hole prepared for it,
whereon the ordinary plunger bar descends, and drives the nail home.
The pointing and shearing of the nail, is effected by means of a V or bevelled
sliding die, which cuts the wire, to a corresponding angular point.
For purpose of ensuring the horn, adapting itself to various thicknesses of soles,
and welts, a weight or spring, is attached to a strap of leather, partly enclosing a
pulley, carried by an arm, supported from a bracket, from the side frame of the
machine, above the pulley, strap is a clip piece, operated from a cam on the main
shaft, by such means, the automatic drop of the horn, is attained, in correct time
with the feed.
For locking the horn in position, whilst the machine is operating, I employ cams
or eccentrics, and connections, which hold the horn stationary, and when the horn
is to be dropped, the cams or eccentrics are off.
By means just described, the powerful spiral spring, applied to the upright of the
horn as heretofore, is dispensed with, and the objectionable marking of the surface
of the sole, as heretofore, is avoided.
The motions for the several parts referred to, are obtained from cams on the
main shaft of the machine.
66
For some class of work, square ended or slug" nails are employed; but for
formation of headed sprigs or fitters, I employ rolled metal bars, of the section
similar to the letter Linverted, from which the springs or fitters are formed, by
slicing or cutting off the ends of the bars. Wood pegs are applied by means set
forth herein, in relation to nails or sprigs of metal, said pegs being cut, from a
continuous length of wood, prepared for such purpose as is well understood.

Improvements in Nailing, Sprigging, and Pegging Machines
employed in Boot and Shoe Manufacture.
I, RICHARD WILKINSON BATEMAN of 8 Hanover Street, Halifax in the
County of York, Shoemaker, do hereby declare the nature of my said 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 improved means and apparatus for operating the
pricker, for cutting and pointing the nails or sprigs, and to operating the "horn"
on which the boot or shoe is received and held whilst under operation.
The boot or shoe, being in position on the horn, the pricker is caused to descend
and pierce the sole, for reception of the nail sprig or peg through the action of a
cam slot, cut in a slide piece, worked by means of a crank pin received in the slot,
said pricker is then carried forward whilst still in the leather, and moving the boot
with it by means of a slide piece operated by cam groove, an arm, side shaft, and a
short slotted lever. The pricker is then withdrawn, by means of the cam slot first
mentioned, and the pricker holder or clamp, is drawn back through the action of a
return spring. The nail or sprig is formed from a continuous length of wire as
ordinary, and when the nail is cut off, it is received in a slide piece, which moves
forward and carries the nail, over the hole prepared for it whereon the ordinary
plunger bar descends and the plunger drives the nail home.
The pointing and shearing of the nail is effected by means of a V or bevelled
sliding die, which cuts the wire to a corresponding angular point.
For purpose of ensuring the horn, adapting itself to various thicknesses of soles,
and welts, a weight or spring is attached to a strap of leather, partly enclosing a
pulley, carried by an arm, supported from a bracket, from the side frame of the
machine, above the pulley strap is a clip piece operated from a cam on the main
shaft, by such means, the automatic drop of the horn is attained in correct time with
the feed.
For locking the horn in position, whilst the machine is operating, I employ
cams or eccentrics, and connections which hold the horn stationary, and when
the horn is to be dropped, the cams or eccentrics are off. By means just
described, the powerful spiral spring applied to the upright or vertical spindle,
of the horn, as heretofore, is dispensed with, and the objectionable marking of the
surface of the sole is avoided.
The motions for the several parts referred to, are obtained from cams on the
main shaft of the machine. Wood pegs are applied by means set forth herein in
relation to nails or sprigs of metal, said pegs being cut, from a continuous length
of wood, prepared for such purpose as is well understood.
Such being the nature and object of this invention the following is a complete
description of same reference being had to the accompanying drawings in which:-

According to this invention the boot or shoe is held in position on the horn 1
the pricker 2 (see Figs. 5, 7, 8 and 9) is caused to descend and pierce the sole
carried on the horn I ready for the reception of the nail, sprig, peg or slug,
through the action of a cam slot 3 cut in the slide piece 4, the latter being worked
by means of the crank pin 5 received in the said cam slot 3. The crank pin 5 15
mounted eccentrically in the disc or plate 6 (see Fig. 5) fixed on the main shaft 7
of the machine. When the pricker 2 has pierced the sole, and whilst still in the
leather, the said pricker 2 is carried forward, and moves the boot or shoe with it,
by means of the slide piece 8 (in which the pricker 2 is fixed) which slides
horizontally in the vertical slide 4 to the position shewn by dotted lines in Fig. 7
being operated by means of the pin or stud 9 fixed in the supplementary slide
piece 10 (see Fig. 54) said pin or stud 9 being operated by the slotted lever 11
mounted on the side shaft 12 which is operated by the lever 15 (see Figs. 4 and 6)
on the end of which is the runner 16 working in a cam groove in the face of the
cam 18 (see Fig. 6).
In front of the supplementary slide piece 10 is a block or guide 13 (see Figs. 5, 5ª
and 6) which can be adjusted and fixed in position by means of the set screws 14, 14.
When the slide piece 4 is depressed (it is shewn raised in Fig. 5) by the action of
the runner 5 the runner 5* on the slide piece 8 comes in contact with the cam end
of the block or guide 13 and the said slide piece 8 and the pricker 2 are moved
forwards or towards the plunger 14" (see Fig. 7) and the downward motion of the
slide piece 4 being continued the pricker 2 is inserted into the sole and while the
pricker 2 is still in the sole the side shaft 12 is operated by the lever 15 and
the slotted lever 11 moves forward the supplementary slide 10 the end of which
now comes in contact with the slide piece 8 and moves the same forward carrying
with it the pricker 2 (see Fig. 7) and boot or shoe under operation. When the
side shaft 12 has made its full movement the pricker 2 will have moved directly
under the plunger 14" (which is shewn down in Fig. 5) whereon the runner 5' by
'the cam slot will withdraw the pricker 2 from the sole and the slide piece 8 is
returned to its normal position by the blade spring 8 (see Figs. 7 and 8) and the
vertical slide 4 and slide 8 are then in the position shewn by Fig. 5. A nail, sprig,

page_text: or rivet is now to be inserted in the hole formed by the pricker 2 and this is
accomplished as follows:-A continuous length of wire is by any one of the well
known "feed" arrangements fed along the channel 17 through the hole 19 (see
Sheets 6 and 8) in the shear box 20 which is stationary and through the hole 21 in
the shear block 22 the hole 21 being brought at the required time into line with
the hole 19 by the shear 22 having an intermittent sliding motion imparted to it by
means of the stud 23 which is received in the block or nut 24 the latter being
carried eccentrically in a recess 25 (see Fig. 10) in the disc 26 the shaft 27 of
which is carried in a pedestal, or in the frame of the machine. An oscillating
motion is imparted to the shaft 27 by the lever 28 on the end of which is a
Below the shear or die 22
runner 29 in a cam groove 30 in the face of the cam 18.
is a nail carrier 31 in which is a hole 32 and a trough or channel 33. The said
nail carrier 31 has a sliding to and fro motion imparted to it by means of the
connecting piece 34 (see Fig. 28) slide bar 35 cranked or L lever 36 (see Fig. 6)
in which is a runner 36* controlled by the cam groove in the periphery of the cam
disc 18.
When the holes 19-21 and 32 are by the cams brought into line the wire from
which the nails, or sprigs are to be formed is fed through such holes and the length,
or that part which extends into the hole 32 (see Fig. 21) is the part which forms
the nail or sprig. The shear or die 22 is now by the action of its cam groove 30
slided and the piece of wire in the hole 32 is cut or sheared off and a nail or sprig
formed and carried in the hole 32 by the nail carrier 31 until said hole 32 and nail
or sprig are directly under the plunger 14 and over the hole last formed by the
pricker 2 in the sole. The plunger 14 is now forced down by any of the ordinary
methods for working such instruments and drives the nail or sprig home in the sole
after which the plunger 14 ascends and the pricker 2 enters the sole, as herein before
described and again moves the boot or shoe forward and leaves the hole under the
plunger 14 ready for another nail or sprig being inserted. When slugs are being
inserted into the sole a straight or plain shear or die 22 is employed, and the
hole 19 in the shear block 20 is made in the shape of a long slot (see Figs. 11
and 13) so that the wire can move with the shear block 22 and is not cut in more
than one place, and no waste is carried, or no nail, or slug, formed which is not
driven into the sole.
When sprigs, or sharp pointed nails are to be made I substitute for the straight
shear 22 a die 37 (see. Figs. 25, 26 and 27) and this die cuts off a triangular piece
and heads the nail formed from the end of the wire, when in the position shewn
Figs. 21 and 22 and the triangular piece which is waste falls into the trough 33 and
so passes out and the hole 19 being in this case as shewn by Sheet 8 the nail or
sprig is sheared off between the shear or die 22 and the hole 19 and a straight
head is formed on the sprig, the end of the wire being left pointed for the
next nail.
For the purpose of ensuring the horu 1 adapting itself to various thicknesses of
soles and welts a weight or spring 38 (see Fig. 1) is attached to a strap of
leather 39 and the said strap of leather 39 partly encircles the pulley 40 (see
Figs. 17 and 18) carried in an arm or fork 41 free to move on a fulcrum stud 42
fixed in the frame of the machine. Mounted in the arm or fork 41 is a curved
flexible finger 43 at the end of which is a block 44 resting on the strap 39. A
tappet 45 is also mounted in the arm a fork 41 and is by link 46 connected to the
vertical rod 47 at the upper end of which is the cranked lever 48 (see Figs. 1. 2
and 3) in the end of which is carried the runner 50 which rests against the cam 51
on the main shaft 7 (see Figs. 4 and 6). One end of the strap 39 is attached to
the link 52 connected to one end of the lever 53 the other end of the lever 53
carrying the vertical spindle 54 which supports the horn 1.
The action of the cam 51 on the runner 50 turns the cranked lever 48 on its
fulcrum stud 55 drawing up the vertical rod 47 and link 46 so that the tappet 45
of the link 46 will force the block 44 tightly against the strap 39 and the latter is
held between the block 44 and the pulley 40, the upward movement of the vertical

page_text: rod then raises the arm or fork 41 on its stud 42 and the strap 39 and link 52 pull
up the end 56 of the lever 53 and consequently the other end of such lever 53 is
depressed and the vertical spindle 54 and the horn 1 are slightly lowered to permit
of the "feed" or movement of the boot or shoe under operation.
When the concentric side of the cam 51 is opposite the runner 50 and
consequently not acting on the latter the parts 41, 45, 46, 47 and 48 resume their
normal positions by coming in contact with the stop pin 49 fixed in the frame of
the machine, and the spiral spring 57 on the vertical spindle 54 raises the horn 1
into position for the nail, sprig or pricker to enter the sole of the boot or shoe on
the horn.
The spring 38 is for the purpose of maintaining even tension on the strap 39 and
taking up the slack.
For the purpose of locking the horn 1 in the raised position I employ the wedges
or blocks 58 (see Figs. 2 and 16) which are received in key beds or slots formed
in the sockets 59 which carry the vertical spindle 54 of the horu 1. The blocks
or wedges 58 are by the links 60 connected with the toggle joint 61 on the end of
the lever 62 (see Fig. 30) which has a slight rocking motion imparted to it by
means of the vertical rod 63 the runner 64 (see Fig. 4) of which is operated by
the cam 65 on the main shaft 7. The vertical rod and cam give the downward
motion, and the spiral spring 66 the return or up motion the lever 62 rocking on its
axis 67. The quick action of the spring 66 shoots the wedges 58 into the beds in
the sockets 59 and so locks the vertical spindle 54 in the raised position, while the
pricker 2 or a nail or slug is being inserted into the hole the lever 62 being thus
controlled by the cam 65 and spring 66 that they turn or straighten the toggle 61
only when the horn 1 is in the raised position and consequently the wedges or
blocks 58 are then only forced into the sockets 59 and wedge and hold the horn
spindle 54 firmly in the raised position. The wedges or blocks 58 are withdrawn
by the toggle 61 and connections and cam 65 before the horn 1 is to be lowered.
By means of the apparatus described for locking the rod 54 and horn 1 in the
raised position the powerful spiral spring usually applied to the spindle 54 is
dispensed with, and a light spring 57 sufficiently strong to raise the horn 1. and
boot or shoe thereon is employed and the boot or shoe being gently raised into
position, the sole of the same is not marked by coming into contact with the feet
of the shear box as heretofore. A hand lever 68 and disc 69 in which is an
eccentric pin 70 are employed for controlling or operating by hand the lever 62 and
toggle 61 when desired or necessary and without moving the vertical rod 63
and when the blocks or wedges 58 are withdrawn from the sockets 59 59 the rod 54
and horn 1 can be depressed by the treadle 72 to permit of a boot or shoe being
placed on the horn.
The main shaft 7 is driven by means of the pulley 73 (both 73 and 74 being
loose on such shaft 7) and the long collar or boss 75 fast on the shaft 7 and in
the collar or boss 75 is a sliding key or locking device 76 which is pressed into
one of the holding notches or recesses 77 in the boss of the pulley 73 by means of
the blade spring 78. When the sliding key 76 is in one of the recesses or notches 77
the pulley 73 is fast on the shaft 7 but the sliding key can immediately be
withdrawn by the lever 79 in which is the slot 80 for receiving the pin 81 in the
said sliding key 76 so that when the lever 79 is moved in the direction of the arrow
(Fig. 4) by means of the inclined or cam lever 82 the machine can be stopped and
restarted at once. The object of the driving pulley 73 being constructed so as to
be loose on its axis is to enable the operator to stop the machine at the end of one
cycle of its motion or at the end of any cycle. The cam lever 82 is controlled by
the lever 83 connecting rod 84 and treadle 85, so that when the latter is depressed
the inclined cam lever is moved clear of the lever 79 and the locking device 76
locks the pulley 73 on the shaft 7 and the machine is driven until pressure is
removed from the treadle 85 whereon the machine is stopped at once. An adjustable
guide or fence 86 (see Sheet 9) is bolted by bolt 89 in a slot or bracket 87 on the
head of the machine, and the edge [of the sole under operation rests against

page_text: the runner or fence 86 thereby determining the distance of the line of nails from
the edge of the sole and each succeeding line of nails from the last line and a slotted
guide plate 88 can be fixed above the runner 86 to prevent the sole leaving such
runner.
I here observe that I am aware that it is not new to insert a pricker into the
sole and cause the pricker to move the sole laterally and I make no general claim
thereto.
Having now particularly described and ascertained the nature and object of my
said invention and in what manner the same is to be performed and carried into
practice I declare that what I claim is :-
