in the Empire of Germany.
ealed the 21st August 1875, and dated the 24th February 1875.
PROVISIONAL SPECIFICATION left by the said Frank Wirth at the
Office of the Commissioners of Patents, with his Petition, on the
24th February 1875.
I, FRANK WIRTH, of the Firm of Wirth and Company, Patent
Agency, of Frankfort-on-the-Main, in the Empire of Germany, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
PEGGING MACHINES TO BE USED IN THE MANUFACTURE OF BOOTS AND SHOES,"
a communication, to be as follows:-

page_text: The boot or shoe, with the last, is fixed on a support in such a
manner that the sole lies upwards. The support can be moved longi-
tudinally and transversely. The shoe or boot is brought in proper
position by means of the support, and by placing the sole below a piston
so that its edge touches the small roll attached to the sole guide.
When in this position the piston with the peg guide previously lifted
is left to fall on the sole by lowering a lever.
I may distinguish the following four movements in the mechanism,
namely:-First, that of the awl; second, that of the hammer; third,
that of the advancing of the wood strap and the operation of the cutter;
and, fourth, the movement of the support.
The said Invention consists :-
First. In the independent action of the awl and hammer, each being
affixed to a separate rod.
Second. In an arrangement by which the peg guide remains in the
same position, whilst the hammer and awl fall through the guide, the
sledge with awl and hammer rods being slid to and fro. ¡
Third. In an arrangement of the support on which the shoe rests,
which support is arrested until the peg is driven in, whereupon it moves
on for a further distance.
Fourth. In the combination of a rod with a quadruple screw, whereby
the guide is lifted in order that the shoe can move forward a distance
for receiving another peg.
Fifth. In an arrangement by which the strap of the pegging wood
is forwarded and the peg is cut off by means of the movement of the
main guide.
Sixth. In the employment of S formed lifting cams, by which the
hammer and awl are lifted.

filed by the said Frank Wirth in the Great Seal Patent Office on
the 21st August 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANK
WIRTH, of the Firm of Wirth and Company, Patent Agency, of
Frankfort-on-the-Main, in the Empire of Germany, send greeting. :
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
PEGGING MACHINES," a communication from Henrich Kuhlmann, a person
resident at Glückstadt, in the Empire of Germany, upon the condition
(amongst others) that I, the said Frank Wirth, my executors or admi-*
nistrators, by an instrument in writing under me, or their, or one of
their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent.
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Frank Wirth, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawings
forming a part of this Specification :—

page_text: Figure 8 is the apparatus for lifting the peg guide.
Figure 9 is the cutting-off apparatus.
Figure 10 is the apparatus for regulating the cutting-off apparatus
with regard of the thickness of the peg.
The boot or shoe with the last is affixed on a support in such a
manner that the sole lays upwards. The support can be moved longi-
tudinally and transversely. The shoe or boot is brought in proper
position by means of the support and by placing the sole below piston 3,
so that its edge touches the small roll 4 attached to the sole guide 5.
When in this position piston 3, with the peg guide 2 previously lifted,
is left to fall on the sole by lowering lever 1. In this movement the
work of the machine begins. By turning main shaft 6, hammer
rod 7, to which the awl is attached, falls on the sole through piston 3,
boring a hole in the sole in order to withdraw itself immediately after.
Said rod moves them forward for one inch with main slide 8 until the
second hammer rod 7¹ is exactly above the piston. During this motion
and simultaneously with it the peg wood advances below the board, and
by means of the forwarding apparatus 9, for the length of a peg; more-
over the knife 12 affixed to knife holder 11 is moved by lever 13 in order
to cut the strap. The cut strap now lays exactly above the piston and
below the hammer 7', but in this movement the latter falls down by
means of main spring 14 in order to drive the cut peg into the sole.
By further turning the main shaft respectively the fly wheel the peg
driver is lifted out of the piston, the peg guide whose piston pressed
against the sole is lifted for 4 inch in order that no hindrance may be
met with by moving the shoe or boot for one peg. distance to the other.
As soon as this movement bas taken place the piston falls upon the sole,.

page_text: the awl falls through the piston driving another hole in the sole. In
this manner the working goes continually on.
We may distinguish the following four movements in the mechanism,
namely-First, that of the awl; second, that of the hammer; third,
that of the advancing of the wood strap and the operation of the cutter;
and, fourth, the movement of the support..
Awl and Peg Driver.-The motion of these two main instruments is
produced directly by the main shaft 6. Shaft 6 is set in motion by
means of the fly wheel, and this latter by means of the treadle 16, which
is in combination with the draw rods 15. Lever discs 17 and 17¹
attached to the shaft turn simultaneously and lay against the small rolls
affixed to the cheeks of the main slide 8. By one rotation the main
slide 8 is exactly moved forward for one inch, or for the distance existing
between the two rods 7 and 71. By this movement awl and hammer are
alternately brought above the piston of the peg guide. On main shaft
their is also arm 18, which seizes alternately the two thumbs 19 and 191
attached to the hammer rods in order to lift these latter. Arrived at
the highest point the thumb retained thus far glides from the cam on
the slide 20 and 21¹, to be retained there until the main slide returns,
finger 19 being at the same time brought over the slit between the two
slides 20 and 21', the awl being driven through piston 3 into the sole
by the action of the main spring 14. These movements go on by turns,
because as soon as one of the rods has attained the highest point, and is
there retained, the other falls down almost immediately after.
The Wood Straps and the Cutter.-The wood straps are rolled up in.
the cross 21, one end is brought behind the small pin tightly on the peg
guide below the advancing wheel 24, between this and the spring behind.
When wheel 24 has catched the wood strap the driving wheels 9, which
are on the same shaft with the advancing wheel, are being set in motion
by hand from the left to the right until the strap touches the knife at
piston 3. When so far in order the machine works for itself, for when
the awl is drawn out of the piston the main slide takes the direction
opposite to the fly wheel, and by this motion the cutting lever 13 is
turned. This lever is connected with the main slide by means of a
sliding piece. By this turning the cutting lever 11 is lifted, together
with the knife 30 attached to it, the wood strap being led to the piston 28.
by means of the advancing wheel 21, and by the combined trigger pin-

page_text: apparatus 9, set in rotating motion in this moment by the inclined
plane 26. Before the peg driver falls down, which only takes place a
moment after the main slide has completed its way, the cutting lever
13 has also returned by means of the motion of the main slide and knife
lever with knife 30 is brought near the peg guide by means of the
inclined plane 29, Figure 9, which is in the knife lever 11, and in which
the head of the cutting lever moves. Thus the cutting of a peg is
effected, in the next moment it is forced into the sole by means of the
peg driver. All these movements are arranged in such a manner that
one operation is completed before the other commences.
The Support. For the purpose of bearing the last with the shoe or
boot to be soled, and for the movement necessary for the work, there is
a support on the table plate 31 respectively on the rails. The lower
side 33 of this support can be moved by means of screw 34 and lever 35.
The cross slide 77, which can be moved very easily, being directed by
the lever 37 glides on four rolls 36 upon the first slide 33. On said
slide there is the hollow saddle 38 with its screw 39, to which the saddle
arm 40 is attached, which arm can be moved round the axis of the
saddle. In front of the saddle arm there is a head piece 42 for the
reception of the last rod 43. Both parts can be adapted for every size.
The last is driven on the last rod 43, so that the front end of the last
lays itself on the leather-covered head piece 44 of the saddle screw.
Below the first slide there is a nut 46, Figure 7, which may be with-
drawn from the screw by means of the handle 45. In this condition the
operator can move the support freely on the gliding ledges 32 in order
that the proper part of the sole can be placed under the piston of the
peg guide. When the cross slide with the saddle has been moved so
far towards the machine that the edge of the sole presses against roll 4.
of the sole guide the advancing movement of the support commences.
Handle 45 is left down, and screw 34 enters into nut 40. Owing to the
rotation of the crank the two disc curves 47 and 48 turn,
and the levers
50 and 51 entering with their rolls in the curve slits move to and fro.
Lever 50 is attached to one end of the small wheel 52, on the other end
of which the long lever 53 is attached, which is connected with lever 55
by rod 54. This lever repeats the upward and downward movements of
lever 53. The partial rotation of screw spindle 34 is caused by the
trigger pin 56 and 56', which enter into the ratchet wheel 57. Thereby
the whole support with the shoe is set in motion. The position of the

page_text: curve disc 48 on spindle 60 can be changed by means of regulating
slide 58 and handle 59. By this regulation the support is capable of
moving at a greater or lesser distance, according to the distance within
which the pegs are to be driven in. In order to fix these distances the
lever 59 is provided with a tooth at its front end, which may be affixed
to a rack at different points. The motion of the second disc curve 47
is in intimate relation with support. This curve moves the double arm
lever 51, and acts by the connecting rod 61 on the crank 62, which is
affixed to a nut 63 in such a manner that it can move upwards and
downwards, but turns with the nut. This nut is combined by means of
a coupling with box 64, around this latter a brake band 65 is attached.
Through this box 64 and nut 63 passes the rod 66. Box and nut turn
in bearings cast on support 67.
This whole machinery serves for the purpose to lift the peg guide at
each time for of an inch before the support is pushed forward, so that
the piston which presses against the sole does not hinder the passing of
the sole under the piston.
The movement of the apparatus is the following:-Immediately before
curve disc 48 produces the quick, almost shock-like motion, of the
support, the roll of lever 68 attached to rod 73 is somewhat moved by
the projection of curve disc 69, and by this movement, as well as by the
lever combination 70 and 71 Below the table the brake band 65 is drawn
around box 64 in such a manner that the peg guide, combined with
the brake spindle 66 is held in its momentary position. In the same
moment the movement of curve disc 47 takes place, which causes the
rotation of screw and nut 60, by which movement brake spindle 66 is
lifted, and by it also the peg guide. Hereupon the curved disc 69 has
turned itself so far that lever 68 gets free, the brake band is loosened,
and the peg guide falls again on the sole, whereupon the awl is driven
into the latter.
Double Stitch Apparatus.-The purpose of the contrivance to be
described is to drive two rows of pegs in the soles. The toothed
wheel 74 attached to the driving wheel 6 is in gear with the twice larger
wheel 75, which in consequence of its size turns twice as fast as the main
wheel. On the side of wheel 75 is cast a curve-like projection, against
which presses a roll, whereupon the apparatus is set in motion by

page_text: If this 5
the slide 78 is moved, which again by its slit, in which the tongue 80 of
the sole guide box 81 enters, produces a translation of the small roll 4.
This take place only at the second turn of the whole machine, because
the larger wheel 75 turns only once while the main shaft turns twice.
By this mechanism the pegging takes place in two rows.
apparatus is to be set out of motion handle 83 is turned. Thus the
excentric connected with the handle pushes the lever 76 with its rolls
so far back that the curve disc cast on the large wheel 75 does not touch
the same.
Having thus fully described the said Invention, and the manner of 10
performing the same, I wish it understood that I claim,—
First. The independent action of awl 7 and hammer 7¹, each being
affixed to a separate rod.
☐ Second. The arrangement by which the peg guide remains in the ¨
same position whilst hammer 7¹ and awl 7˝ fall through the guide, the 15
sledge with awl and hammer rods being slid to and fro.
Third. The arrangement of the support on which the shoe rests, which
support is arrested until the peg is driven in, whereupon it moves on for
a further distance.
Fourth. The combination of rod 66 with a guide cap screw,
the guide is lifted.
whereby
Fifth. The arrangement by which the strap of the pegging wood is
forwarded by the main guide.8.
Sixth. The S formed lifting camis 18 by which hammer and awl are
lifted.
In witness whereof, I, the said Frank Wirth, have hereunto set
my hand and seal, this Twenty-ninth day of July, in the year of
our Lord One thousand eight hundred and seventy-five.
