page_text: WHEREAS I am in possession of an Invention for "AN IMPROVED
MACHINE FOR PEGGING BOOTS AND SHOES," and have petitioned Her Majesty
to grant unto me, my executors, administrators, and assigns, Her Royal
Letters Patent for the same, and have made solemn Declaration that
it has been communicated to me from abroad by David Childs Rogers, of
Conway, Massachusetts, United States of America.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed, in and by the
following statement, reference being had to the accompanying Drawings
forming a part of this Specification :-
My Invention relates to certain improvements in machines for pegging
boots and shoes operated by a crank described in the Specification of an
Invention for which Letters Patent were granted to George Haseltine,
bearing date the 8th day of December, A.D. 1866, No. 3237; and my
Invention consists in operating the driving bar by a rack and pinion,
the rack being secured to the driving bar, and the pinion (which is
revolved by a crank) being provided with teeth on a portion only of its
surface.
My Invention also consists in producing a positive motion of the feed
lever by means of a cam, and it also consists in an improved device for
adjusting the gauge to regulate the distance of the pegs from the edge
of the sole.
The said Invention furthermore consists in improved mechanism for
feeding the peg wood forward into the peg tube at the required time,
and in a peg tube of peculiar form and peg holder to be referred to
hereafter.
To enable others skilled in the art to understand and use my Invention
I will proceed to describe the manner in which I have carried it into
practice.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of a machine for pegging boots and shoes
with my improvements applied thereto; Figure 2 is an end elevation of
the same; Figure 3 is a section on the line x, x, Figure 1; Figure 4 is a
plan of the under side of my improved machine; Figure 5 is a horizontal
section representing the manner in which the peg wood is fed forward

page_text: within the peg tube to have a peg split therefrom by the knife;
Figures 6, 7, 8, 9, and 10 represent detached portions of my Invention.
In the said Drawings, A is the framework in suitable bearings, in
which runs the driving shaft B actuated by hand power applied to the
crank C; D is a pinion upon the driving shaft, a portion only of the
pinion being provided with teeth, which engage with a rack E secured.
ly set screws a to a vertical' driving bar G, which moves in bearings in
the frame A, and is surrounded by a spiral spring H, the upper end of
which bears against the under side of a plug or collar I screwed into
the top of the frame A, while the lower end of the spring rests upon a
collar K secured' to the driving bar by a set screw d, and made adjustable
thereon so as to regulate the tension of the spring H and consequently
the force of the blow. By means of this plug I the spring H can be
readily removed or inserted in plàco from the top of the machine in a
convenient and expeditious manner. As the crank G'is revolved in the
direction of the arrow 20, the toothed portion of the pinion D is brought
around so as to engage with the rack E, and the driving bar is thus
raised until the blank portion of the pinion is brought opposite to the
rack, when the driving bar G is instantly carried down as required by
the action of the spring. The rack E fits snugly between the sides of:
tlic slot L of tlic frame, which tlius serves in connection with the other
bearings to guide and prevent any lateral play of the driving bar, and
Keep it always in a proper position for performing its office. The lower
end of the driving bar G is of the form shewn in section, Figure 3, and
is provided witli an aperture for the reception of an awl e, and in a
siinilar aperture-bored in the driving bar is placed a rod or peg driver f
After tlic awl'e and peg driver fare adjusted' to their proper lieights they
are secured in place by screws g, h, and as they are both thus attached
to the driving bar they can have no movement independently of each
other. The upper end of the driving bar G projects through the frame-
work A, and terminates in a screw, upon which turn nuts M; below
wlich and around the driving bar are placed leather or other clastic
washers 21 for the purpose of reducing the force of the concussion
consequent on the sudden descent of tlic driving bar, and as the
washiers 21 are gradually worn away the nuts M may be screwed down-
upon them. The height of the nuts M may be so regulated as to keep
the bottom of the awl stock or driving bar always a little above the solo
when the hole is punelied, thereby preventing the sole from being

page_text: injured. N is a plate screwed to the bottom of the framework, the inner
end of this plate being provided with a passage which forms a peg tube i
for the reception of a single peg and for the peg driver f to work in.
On one side of the plate N is formed a narrow vertical slot k (see
Figure 9), which communicates with the peg tube i and allows the
passage of the peg wood 7, while the opposite side of the plate N is
provided with a narrow vertical slot m (Figure 10) (also communicating
with the peg tube), into which the edge of a knife O projects to sever a
peg from the strip of peg wood on the ascent of the peg driver, as will
be more particularly described hereafter. The peg wood is coiled upon
a frame or holder P, which is screwed at n to an arm Q projecting from
the side of the framework A, and is conducted through a passage formed
between the side of the framework on one side and an adjustable plate o
on the other side, the top of the plate being provided with a shoulder 22,
which rests upon the top of the peg wood and serves to guide it in its
passage to the peg tube, the plate being also provided with a slotted
arm through which passes a screw 23, by means of which the plate may
be adjusted to accommodate peg wood of varying widths.
The motion of the machine along the edge of the sole for the purpose of
spacing the distances between the pegs is accomplished by the following
means: To one side of the framework A is pivoted at 24 a lever R,
the lower end of which is curved around so as to form an elbow or foot
piece p, through which is cut a slot 25 for the passage of the awl and
peg driver; the under side of this elbow or foot piece p resting upon the
sole of the boot or shoe to be pegged, and being serrated or provided
with notches 26 to prevent it from sliding when resting thereon. The
upper end of the lever R extends some distance above the point 24, at
which it is pivoted, and is provided with a slot 27, through which and
into a roller (Figure 7) passes a stud 28 provided with a nut 29, the
roller being free to revolve. S is a cam secured to the end of the
driving shaft opposite the end to which the crank C is connected. The
interior of this cam S is provided with a groover of the form seen in
Figure 2, in which the roller q is made to turn on the revolution of the
driving shaft. The form of the groover produces the required vibration
of the lever R upon the frame, and consequently the amount of feed or
distance between two successive pegs. The degree of vibration of the
lever R may
be varied by sliding the stud of the roller in the slot 27 to
or from the pivot 24, and tightening the nut 29 when the stud is adjusted
9

page_text: in the required position. The above-described construction only admits
of a slight amount of variation in the distance between two consecutive
pegs, but in order to vary the distance between the pegs to a still greater
extent the awl may be secured to a stock made separately from the foot
of the driving bar, but secured thereto by means of an adjustable clamp.
It is evident that these two adjustments must be made together in order
that the amount of "throw" or "walk" of the foot piece p may correspond
exactly with the distance between the awl and peg driver. T is a gauge
by which the distance of the pegs from the edge of the sole is regulated.
This gauge is pivoted at 30 to the lever R, and is bent around under-
neath its lower curved portion, the extremity of the gauge which rests
against the edge of the sole being rounded and prevented from moving
laterally by a pin 31 fitting into a slot 32. The construction of this
gauge and the manner in which it is pivoted is such that it constantly
exerts a tendency to spring out from the lever R, a lever U pivoted to a
lug 33 projecting therefrom and passing through a slot 34 in the gauge,
being employed for throwing the gauge forward to the required position.
The inner end of the lever U is provided with two faces at different
distances from the point to which it is pivoted (see Figure 7), so that
when raised as indicated in black the gauge will be thrown forward
toward the awl, while when this lever is depressed, as seen in red, the
gauge will be carried back from the awl, thus removing the line of pegs
further from the edge of the sole. The outer end of the knife O is
secured to an arm V, projecting from the lever R by a screw s passing
through an open slott in the outer end of the knife, which may in this
way be adjusted as required; the blade of this knife is made flexible
and bears against the inside of the peg tube and holds the
peg in place
after being cut. The peg tube is of a square or diamond shape in cross
section, instead of round as heretofore, so as to prevent the inner corner of
the peg from being pressed out of shape, as is liable to be the case where
it is forced against the side of a round tube.
The manner of feeding the peg wood forward into the peg tube will
now be described. X is a vertical shaft which revolves in an extended
bearing 35, and carries at its lower end a toothed roll u which passes
through an opening 36 in the plate o (Figure 8), and bears against the
peg wood. The upper end of the shaft X is provided with a ratchet
wheel 37, which is operated by a pawl 38 pivoted to the lower end of a
lever Y, which is pivoted to the framework at 39, and carries at its

page_text: upper end a roll 40, which bears against the exterior surface of the
cam S, see Figure 2, the upper end of the lever Y with its roll being
held against the cam, and the pawl 38 kept in contact with the teeth
of the ratchet 37 by a spiral spring 41, by which construction as the
cam revolves the toothed roll u through the connections above described
is caused to feed the peg wood into the peg tube at the required intervals
a determinate distance equal to the width of a single peg. Z is a guard
extending around that portion of the framework grasped by the hand,
which is thus protected from injury which might otherwise result from
the descent of the driving bar. The awl e and peg driver f being down,
and the peg wood being placed on the peg holder and led into the
entrance of the peg tube i, the distance to which the pegs should be
placed from the edge of the sole is regulated by the gauge T when
the operator grasps the upper portion of the frame by applying onc
hand within the guard Z, and the awl is pressed into the sole by the
weight of the machine, in which position the roll q is at the com-
mencement of the eccentric portion of the cam groove r. The crank
is now turned by the other hand, and the cam is revolved so as to cause
the roll to pass through the eccentric portion of the groover, thus
vibrating the lever R on its pivot 24 and carrying with it the slotted
feed foot or foot picce p; the crank continuing to revolve the toothed
portion of the pinion D engages with the rack E, and raises the driving
bar G against the resistance of the spiral spring II, and the teeth
of the foot piece p are brought down upon the sole when the awl is
withdrawn therefrom; the awl and peg driver continue to rise with
the driving bar, when the frame A is advanced by its vibration on the
lever R, carrying with it the driving bar G, with the awl e and peg
driver secured thereto. As soon as the peg driver has risen above the
slot in the peg tube, the peg wood is fed therein by the toothed roll,
and the knife is brought forward by the vibration of the lever R which
splits off a single peg. The latter is retained by the knife in the peg
tube in a position to be struck squarely by the peg driver just previous
to the descent of which the knife is withdrawn from the peg tube. As
the crank continues to be revolved the blank portion of the pinion D is
brought opposite to the rack when the spring is released, carrying with
it the driving bar G which drives the awl e into the sole to punch a
new hole; the peg driver simultaneously descends and drives a peg into
the hole last made by the awl, when the operation of feeding the machine
forward continues as above described.

me by my foreign correspondent, and shown how the same may be
