Improvements in Machines for Furnishing Boots and Shoes with
Wooden Pegs.
1 DAVID MAYER, Manufacturer of Schwabisch Gmünd in the Kingdom of Wurtem-
burg and 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
This invention relates to a machine to provide boots and shoes with wooden pegs
which has as compared with other similar machines-the advantage that owing to
the alternate motion of two tools a hole is first made and the peg inserted in such hole
without having to raise or otherwise displace the apparatus. Hence no peg can
possibly be missed or left out.
Moreover the machine cuts the pegs automatically off a wooden band although this
arrangement can be thrown out of use in a very simple manner when the punching
of holes is merely contemplated.
Finally the uniformity of the intervals between the pegs is secured by means of an
adjustable carrier foot.
In the accompanying drawings
Figure 1 is a rear view and
Figure 2 a front view of the machine.
Figure 3 shows the inside mechanism the cover plate having been removed.
Figure 4 is a plan partly in section.
Figure 5 is a rear view of the machine in another position and
Figure 6 is a side view thereof.
Figure 7 shows the cutting and driving tool provided with a knife.
Figure 8 is a section on line x a of Figure 1.
In a frame or shell p formed of two parts connected together by means of screws are
arranged the two toothed tools a and b the former being a driver and a cutter and the
other carrying an awl. These tools are inclined towards one another in such a manner
that their teeth gear with the toothed wheels and that they converge at the point q
Figure 3. By striking blows with a hammer upon the tools a and b alternately the
latter move also alternately up and down under the influence of the toothed wheel s
so that one tool is lowered at the same time as the other is raised (Figure 3). The
tool a (Figure 7) carries at its lower end a driver a fixed by a screw as well as a
knife a. When the tool a is hammered down the driver a forces a peg in the hole
previously formed by the awl b² carried by the tool b the two tools operating owing to
their inclined position upon one and the same point g. At the same time the knife a³
likewise fixed to the driver a cuts the next peg off a suitable wooden strip peg band
or board o (Figures 4 and 6) inserted for this purpose in the machine. The tools a
and 6 carry the projections or spurs a' and 'which are guided through corresponding
openings formed in the frame » (Figure 1) in order to limit the up and down motion
of the said tools.
P
The wooden peg band or board o consists of a strip of any suitable wood which has
a suitable form so that the pegs may be directed towards one another (Figure 6) the
direction of the fibres being consequently vertical each single peg being thus easily
severed by the knife a³ as it moves down. To facilitate the insertion of the pegs the
wooden peg band or board is further bevelled in a downward direction. The
continuous feeding of the wooden band strip or board o (which is held in position in
the slot p² of the franie p by the edge d' of the rail d which is adjustable on d¹ and

page_text: by the grooved roller h) is carried out by the latter roller which rotates in a suitable
direction. This is effected by the pawl which actuates the ratchet wheel f mounted
with the fluted roller h upon the shaft and by means of a set of levers in the
following manner. As the tool a descends the lever n pivoting at n¹ is moved forward
issuing from the position shown in Figure 2 to enter that shown in Figure 3. The
lever n actuates now the crank lever pivoted at 93 (Figure 4) and which is connected
with the pawl g. The latter engages with the teeth of a ratchet wheel mounted
together upon the same shaft with the fluted roller which feeds the wooden strip or
band o so that accordingly the said strip or band is moved a tooth of the ratchet
wheel at each up and down motion of the tool a and is consequently driven under the
knife. The lever n subjected to the action of the spiral spring fixed to the crank
lever g2 and to the thumb piece is constantly brought under the tool a that is to say,
in the position shown in Figure 2 to be acted upon by each downward movement of the
tool a.
The pawl g is held in gear with the teeth of the ratchet wheel by means of a
flat spring g' fixed to the crank lever g³.
The mechanism for feeding the wooden strip or band is arranged in a handle e¹
pivoting upon e and can be thrown out of use as soon as this handle is turned to the
right hand side when it is only intended to punch holes without inserting the pegs at
the same time the lower end of the shaft carrying the fluted roller is thereby
withdrawn from its bearing (Figure 5).
After a part has been firmly pegged through double hammering first on the tool b
for punching and then on the tool a for driving the pegs while a further wooden peg
has at the same time been severed from the timely fed wooden strip or band by the
knife a³ the apparatus is shifted to rivet the next part.
To regulate uniformly the intervals between the pegs a carrier foot i (Figure 2)
pivoting at is provided. To further move the apparatus the same is turned upon its
supporting point i.e. upon the pivoting point of the carrier foot so that the lower end
of the apparatus may be moved to the left hand side by the bearing point of the rigid
carrier foot until the set screw m of the apparatus strikes against the said carrier foot.
When the apparatus is brought again in position over the sole which is being
pegged the same is turned to the left care being taken that the latter should not leave
its bearing point on the carrier foot until it has found another bearing point on its
lower end it is then set up in an upright position the serrations of the carrier foot as well
as those formed in the apparatus preventing slipping. The said apparatus is moved the
desired distance and the carrier foot is pushed back by the flat spring into its former
position the sole being now further perforated aud pegged. The interval between the
nails can be varied by means of the set screw m.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A machine for furnishing boots and shoes with wooden pegs by tools arranged
in a frame inclined downwardly towards each other and provided with teeth one of
which carries an awl for making holes while the other carries a driver for pegging
and a knife for cutting the pegs off a wooden strip band or board the said tools being
moved up and down by means of blows delivered with a hammer upon one of them with
the aid of a toothed wheel gearing with the teeth of the said tools substantially as
hereinbefore described and represented in the drawings hereto annexed.
2. In wood pegging machines the automatic feed of a wooden peg band strip or
board by means of a fluted roller which is rotated by one of the tools with the aid of
a pawl actuated by a set of levers this mechanism being thrown out of use by merely
turning a handle substantially as hereinbefore described and represented in the
drawings hereto annexed.
3. In wood pegging machines the mechanism for obtaining a uniform interval.
between the various pegs consisting of a pivoting carrier foot the angle of rotation of

page_text: which is regulated by a set screw and upon which the wood pegging machine is
supported so that it can be moved a determined distance in a determined angle after
turning and be set upright upon the sole requiring to be pegged substantially as
herein before described and represented in the drawings hereto annexed.
