Improvements in Machines for Pegging Boots and Shoes.
I, RUDOLPH LEY, manufacturer of Arnstadt in Thuringia and subject of the
Prince of Schwarzburg-Sondershausen, German Empire 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 invention relates to certain new and useful improvements in machines for
pegging boots and shoes without using lasts, of which the following is an exact
description.
In order to make my description more clear, I refer to the accompanying drawings
in which similar letters denote similar parts throughout the several views.
Fig. 1 shows a front elevation of the whole machine.
Fig. 2 shows a side elevation of the same.
Fig. 3 shows a front elevation of the upper part of the machine drawn to a larger
scale.
Fig. 4 shows a side elevation of the same.
Fig. 5 shows a section along line A B in fig. 3.
Fig. 6 shows a guide plate a drawn to a larger scale.
Fig. 7 shows a section through the same.
Fig. 8 shows an enlarged view of the head the shoe holder or last.
Fig. 9 shows an enlarged view of the arrangement for cutting off the peg inside
the shoe.
Fig. 10 is a top view of the lever l' and sector k².
The principal points in my improved machine are the following:
I. Arrangement for boring the hole for the reception of the peg in the sole of the
shoe.
II. Arrangement for cutting off the peg from the strips of wood fed into the
machine.
III. Arrangement for driving the peg into the hole in the sole of the shoe.
IV. Arrangement for cutting off the end of the peg inside the shoe.
V. Arrangement for transporting the shoe forward the required distance between
the pegs for single rows of pegs or of moving the shoe zig zag forwards when two
rows of pegs are required.
These five movements are more narrowly described in the following.
I. AND III.
ARRANGEMENT FOR BORING THE SOLE (I) AND FOR DRIVING THe peg
INTO THE HOLE IN THE SAME (III).
Since these two points in my improved machine are very closely connected, it will
be more clear to describe them together.
To the upper part of the standard S which is fixed to the main standard 5 of the
machine, the guide a is fastened by means of the bracket 6°. The shape of this guide a
will be best seen in figs. 3 and 4. This guide a ends above in the hollow cylinder b
in which the hammer rod c slides and projects through above. The nut i is screwed
on to the end projecting through above the cylinder b, which nut prevents the
hammer e from falling too far down when it is let loose. The hammer rod c has a
greater diameter at h and a collar at c¹. On this collar c¹ rests a spring ², the other
end of which presses against the inside of the guide a, so that the hammer rod c is
always under the influence of the spring c², which tends to press it downwards. The
shaft k has its bearings in the sides of the guide a and is driven by bevel wheels from
shaft the latter being set in motion by the pedal M³, connecting rod M³ and fly
wheel M³, it can also be driven by sheave pulleys from a main shaft. To the shaft K
are fixed the two bent forked levers as a which when the shaft is turned round come

page_text: under the corners of the block and push the hammer rod c upwards. The hammer
rod c on being let loose falls under the influence of the spring c².
As there are two of these forked levers as a fixed to the shaft k, the hammer will
of course rise and fall twice to each revolution of the shaft k. A short distance from
the lower end of the hammer rod c are two square notches e c³ cut in the same, these
notches serve for raising the awl and pegging blocks de. The awl block d and
hammering or pegging block e slide vertically up and down in the guide formed by
the back plate z (fig. 5) and this back plate z slides in its turn horizontally to the
right and left in the guide q which is moveably attached to the upper standards of
the machine. The horizontal sliding of the plate z is effected by the cam in the
disc c c on the shaft k. The roller d of the lever arm d d runs in this cam and by
this means the oscillation of the arm d d is brought about. The oscillation is com-
municated to the plate z by the connecting piece d d ; the awl block d and hammer
block e are the same shape and lie next each other as will be seen from fig. 5. Each
of the two blocks has two projections. The awl block d has the projections d' and d³,
the hammer c descending strikes the projection d' driving the awlf through the sole
of the shoe whilst the projection de passes into the notch c of the hammer c when
the back plate z is pushed to the left in fig. 5 and in consequence the awl block is
taken up with the hammer. When the awl block d is down, the hammer block e is
always in its highest position as shown in fig. 3. The working of this part of the
machine is as follows:
Assuming that the awlf has just been driven through the sole (fig. 3) and that the
plate has just been moved to the left (fig. 5) so that the projection d³ has just passed
into the notch c of the hammer rod c. As the disc c c revolves further, the arm a
comes under the projection on the hammer rod c and lifts the hammer and with it
the awl block d whilst the lever arm d d and of course the plate z remain stationary
owing to the concentricity of the cam on the disc c c which remains concentric for the
next half turn. As soon as the hammer rod c has reached its highest point, the roller
on the lever arm d d comes into the eccentric part of the cam and thereby pushes the
back plate to the right (fig. 5) and with it the awl block d and hammer block e.
The awl block d is so pushed on to the horizontal projection of the resting plate b b
(figs. 3 and 4) and remains there until z is again pushed to the left. The hammer
block e however which has been lying on the left hand side of the resting slab bb
becomes free and the long thin hammer g which is attached to the block is brought
exactly over the hole in the stationary block a from which the awl has just been
lifted out. In the mean time a wooden peg has been brought into this hole in the
block (by mechanism described in the next paragraph). The disc c c'has now
revolved so far that the fork arm a³ comes away from this projection / and the
hammer rod c is released and falls down under the pressure of the spring on to
the projection of the hammer block e driving the hammer g through the hole in the
block and the wooden peg through the hole in the sole which was previously
bored by the awl. By the further revolving of the disc c c the plate is again
pushed to the left, the hammer c is again raised by the second fork lever a³, taking
with it the hammer block e since the projection e³ has been pushed into the left hand
notch on the hammer rod. As soon as the hammer has again reached its highest
point the plate is moved to the right, the hammer block e is laid on the stationary
resting plate bb and the awl block d is pushed off the resting plate to be driven
down by the second descension of the hammer. In the mean time the shoe sole
has been transported by the mechanism herein after described. As will be seen by
each revolution of the disc c c the hammer rod c rises and falls twice, the first
time driving the awl through the sole, the second time driving the peg into the
same.
1. ARRANGEMENT FOR CUTTING OFF THE PEG AND PLACING THE SAME UNDER THE
Tl
HAMMER.
11.
and 7
In this

page_text: other the wood shaving is fed by means of roller n and guides. These movements
take place in the following manner: the block a remains stationary. Fixed to the
upper part of the machine in any convenient manner is the vertical tubular
shaft vand in this hollow shaft the shaft vl runs. On the lower end of this shaft is
fixed the small roughed wheel 2 for transporting the wood shaving and on the upper
end is fixed the ratchet wheel 8 by means of which the shaft v¹ receives its motion.
The ratchet wheel is worked by the catch w¹ which is connected to the lever w
pivoted at w². This lever w receives its motion from the eccentric m against which
it is continually held by a spring, so that by each complete revolution of the shaft k
the ratchet wheel is moved one tooth further and the roughed transport wheel v³
moves the wood shaving just as much as is required for one peg. The knife x' (fig. 4)
which works in the slit 2 of the block a receives its motion from the eccentric m by
means of the double lever army which turns on its pivot in the under part of the
guide a. The one end of this lever is held against the slanting side of the
eccentric m (from which it receives its motion) by means of a spring and to the other
end is fixed the knife so that by one revolution of the shaft k the knife 27 passes
into the slit of the block a and cuts off the peg which remains there until the
hammer g enters the hole in the block x from above and drives the peg just cut off
into the sole of the boot.
IV. ARRANGEMENT FOR CUTTING OFF THE END OF THE PEG INSIDE OF THE SHOE.
The hollow shaft al (figs. 1 and 2) is supported in the bearings p³ p³ fixed to the
main standard of the machine and fixed to this hollow shaft a' is the hollow knee
shaped support 6 for holding the' shoe. Inside the hollow shaft a' is a second
shaft passing through the whole length of the hollow shaft a¹ and resting with its
under end on a conical screw carried by the angle piece p' fixed to the main
standard . The other end of this shaft f¹ lies in the hollow of the shoe holder or
last 6', and has keyed to it the bevel wheel p8; this wheel gears into another bevel
wheel p which is keyed to the horizontal shaft in lying in the hollow last b¹. On
the other end of shaft m¹ is another bevel wheel q gearing into wheel q' and thus
driving shaft m² which lies at an angle of 45° to the shaft m¹ in the vertical plane.
The shaft m² has on its upper end a toothed cone (fig. 8) which drives the bevel
wheel n¹. Eccentrically fixed to the upper surface of this wheel n' is the knife for
cutting off the end of the peg inside the shoe (figs. 8 & 9); the cutting edge of this
knife lies in the horizontal plane and describes a circle by each revolution of the
bevel wheel n¹. The whole gearing arrangement just described receives it motion by
means of the cog wheel 1 fixed to the bottom end of the vertical shaft f¹ (fig. 2)
and into which the toothed segment k¹ works. The toothed segment k¹ turns on its
centre and is moved from the pedal shaft d' by the lever arrangement pivoted
at 62 and connected with the segment k (as shown in fig. 10). From this it will be
seen that by each up and down motion of the pedal the knife on the wheel n¹ will
make one revolution and that takes place exactly after the hammer g has driven the
peg into the sole of the shoe, so that the end of this peg will be cut off before the
shoe sole is removed by the transporting apparatus.
V. ARRANGEMENT FOR TRANSPORTING THE SHOE FORWARDS THE REQUIRED DISTANCE
BETWEEN THE PEGS FOR SINGLE ROWS OF PEGS OR OF MOVING THE SAME
FORWARDS IN A ZIGZAG MANNER WHEN TWO ROWS OF PEGS ARE REQUIRED.
Close by the hole in the block a where the awl comes through, is placed a small
curved piece of metal u provided with small spikes on its under surface. It is
supported and moveable in two directions by means of the bent arm qq (fig. 4). The
transporting apparatus for one row of pegs receives its motion by means of the
eccentric m and in the following manner pivoted to the side of the guide a is a lever
árm o having at its upper end a roller R which runs on the rim of the eccentric m
and is oscillated thereby backwards and forwards. This lever arm o has a groove.cnt
in the back part of it and a roller R¹ runs in this groove.
The roller R is adjustably fixed to one end of a double armed lever p, which is

page_text: pivoted to the machine-frame at 75 and into the other end of which the bent arm q is
able to slide vertically up and down.
By moving the roller R' higher up, the upper arm of the lever p p becomes longer
and in consequence the lower arm describes a shorter way at each oscillation, whilst
by placing the roller lower down the upper arm becomes shorter and the way described
by the lower arm longer. By this means it is possible to regulate the distance between
the pegs in the sole of the boot.
The arm q is under influence of the spring, which continually tends to draw it
upwards.
On the shaft k besides the eccentrics m and cc is an eccentric disc ragainst the side
of which the bent lever t is continually held by means of the spring ³. The bent
lever is pivoted at s and its other end rests on the top of the rod q. When the
sbaft revolves, the rod q receives an up and down motion by means of the lever t
and disc r. The working of this part of the machine is the following:
When the shaft k revolves, the lever arm p p will be oscillated by means of the
eccentric m and lever arm and with it the arm q and curved piece u. The curved
piece u with its spikes will however during the oscillation be pressed down on to the
shoe sole by the working of the disc r on the bent lever t, so that by each revolution
of the shaft k the shoe sole will be moved forwards by exactly so much as shall
correspond to the required distance between the pegs, i.e. according to how the
roller R¹ has previously been regulated.
When two rows of pegs are required the shoe must be moved forwards in a zig zag
manner which is accomplished by the following mechanism.
On the shaft is a cog wheel e e, which gears into a cog wheel ff which runs on
the pivot o. In the side of the cog wheel ff is a cam in which a roller runs which is
fixed on the end of the bent lever arm g g which is pivoted at o°. The one end of this
bent lever g g has a slit in which the roller h h of the lever armi i moves; the other
end of the arm ii is fixed to the block o' in which the lever arm g is fixed and which
is moveable on the bolts which run in slits. When now two rows of pegs are
required, the action is as follows: when the spiked piece u is being moved forwards
(as in the manner described above when only one row of pegs is desired), the whole
piece o containing the levers q and p is moved by the cog wheels e e and fƒ and
levers gg and ii in a direction at right angles in the horizontal plane to that given
to it by levers p and q and in consequence the shoe will be moved forwards in a zig-
zag manner and two rows of pegs will be made. Should only one row of pegs be
required the cog wheel ee may be detached from the disc 2 by means of a screw;
the cog wheel is loose on the shaft whilst the disc is keyed on to the same so that
when the cog wheel ee is loosened the dise alone revolves and the cog wheels e e
and ff and in consequence the zigzig motion of the transporter u are placed out
of gear.
It only remains now to describe the manner in which the work may be taken out
of the machine whilst the same is in motion. To the lower end of the hollow shaft a¹
is loosely fixed a fork o³ connected by means of a rod with the second pedal d¹ which
is loose on the pedal shaft d³. The hollow shaft a¹ can slide vertically up and down
in its bearings p p but is continually being drawn upwards under the influence of
the springs o o¹. If it is desired to remove the shoe from the machine for a moment
without stopping the same, it is only necessary to press the pedal d down when the
hollow shaft is drawn downwards and with it the last 6' so that the shoe is placed
out of reach of the awl and hammer. In order to relieve the shoe from the pressure
of the spiked curved transporter u whilst the machine is not working, the lever e¹ is
fixed to the side of the machine and on being moved forwards catches on to the
pin e on the fork o³ pressing the same down when the last 61 is also pressed
downwards.
Having now described the manner in which each separate part of the machine
functions, it now remains to describe the working of the whole machine:
When the shaft makes one revolution, the shaft k will also make one revolution as
the bevel wheels are the same size. During one revolution of the shaft k the whole

page_text: five movements just described take place in the following order: the shoe is first
placed on the last b¹.
First quarter of the turn: raising the hammer rod c by means of one of the fork
levers a and with it the hammer g and hammer block e, movement of the back
plate towards the right (fig. 5) by means of lever arm dd and thereby placing
haminer block e on left hand side of resting plate b b and releasing awl block d
from right hand side of the resting plate 66 and bringing projection d³ of the same
into notch c of hammer rod c.
Second quarter turn: releasing of hammer rod c and falling of the same under
influence of spring c² with the awl block d whereby awl f is driven through the
sole of the shoe.
Third quarter turn: upward movement of hammer rod c and with it awl block d,
movement of back plate to left (fig. 5) thereby releasing hammer block e
from resting plate bb and bringing projection e of the same into left band
notch c³ of hammer rod c and bringing resting plate 6 6 under awl block d so
that the same is held from falling: turning of ratchet wheel ³ one tooth whereby
wood shaving is pushed into slit in block x and pushing knife into slit
block cutting off peg and drawing knife back.
in
Fourth quarter turn: descension of hammer rod c with hammer 9 driving pog
into the sole of shoe; cutting off the end of peg inside the shoe by the knife
bevel wheel n¹; transport of shoe by means of curved spiked piece u, lever
arms q, o, p and t and discs and m the required distance between the pegs
when two rows are required in a zigzag direction with help of cog wheels e e
and ff and levers 9 g, h h and ii. The shoe can be placed out of reach of the
hammer and awl at any time by means of the pedal d¹ in the manner previously
described.
