States of America, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
MACHINERY FOR PEGGING BOOTS AND SHOES," and have petitioned Her most
Excellent Majesty Queen Victoria to grant unto me, my executors,
administrators, and assigns, Her Royal Letters Patent for the said

page_text: Invention, and have made solemn Declaration that the same is the result
partly of a communication from William Rhodolphus Landfear, a person
resident at Jersey City, State of New Jersey, of the United States.
aforesaid, and partly of an Invention and discovery made by me.
NOW KNOW YE, that I, the said David Whittemore, 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 state-
ment:-
This Invention relates to that class of pegging machines in which the
boot or shoe is held upon a jack and pressed up against a feeding device
which moves it under the awl and driver at the proper speed for the sole
to be perforated and pegged in the well known manner.
•
The nature of my Invention consists as follows:-The combination
and arrangement of the feed mechanism or sleeve with the peg driver
and awl mechanism, or devices for operating the feeding sleeve; mechanism
or means for effecting a direct and convenient movement of the peg wood
or severed peg to the driver; mechanism or means for shifting the line
of pegging without stopping the machine; means of preventing any
backward movement of the peg wood while being cut by the knife;
mechanism for holding the peg wood in its passage to the driver; the
application of an adjustable brake to control the movement of the shoe
feeding sleeve or prevent any back action thereof; mechanism for
compressing or condensing the peg wood; the arrangement of the. knife
with respect to the peg wood passage and the driver, whereby by a lateral
thrust of the knife a single peg is cut from the strip and driven before
another is severed; in making the sides or mouth of the peg wood
carrier adjustable in order to compensate for any wear thereof; in a
new device for guiding the awl and driver; in an improved stop motion
for arresting the action of the machine; in an improved jack for sup-
porting the boot or shoe and enabling it to be turned and maintained
in any desirable position while being pegged, all as herein-after more
fully set forth.
t
To enable others skilled in the art to make and use my Invention I
will proceed to describe its construction and operation, referring to the
accompanying Drawings and the letters of reference marked thereon.

་
In the said Drawings' A² denotes the bed or frame to which the
working parts of the pegging mechanism are affixed, the said bed being
supported upon a pedestal A³. A denotes a pitman which connects the.
gear wheels B, C, the latter of which is disposed on the rear end of the
main driving shaft D, to which the fly wheel D¹ is attached. This
pitman may be connected with a treadle to be worked by the foot of the
operator, or the machine may be driven by power from any suitable
prime motor. To the front end of the shaft D a crank wheel E is
affixed, as shown in Figure 3, which is connected by the crank pin G.
with the sliding block H, which reciprocates horizontally in slot I
formed in the sliding cross head J. This cross head J has a reciprocating
vertical movement in guides J¹, J³, in obedience to the action of the
block H driven by the crank pin G. To the cross head is attached the
awl stock' K which carries the awl L and rises and falls with the head J.
The driver stock M works in a groove in the cross head and is indepen-
dent' in its movements of the head. It has a toe N projecting from it.
which is engaged by the block H as the crank revolves, and by which
the stock M is raised. When by the further revolution of the crank the
block H slips out from under the toe N, the driver stock is forcibly.
:

page_text: impelled downward by the action of the spring S. The driver O is
attached to the lower end of the stock M. P is a hollow tube called a
"chimney" in which the driver stock M moves. The upper end of the
stock M has a screw thread on it which receives the nut Q. Washers R
intervene between the top of the chimney and the lower surface of the
nut Q. The object of this arrangement is to adjust. the stroke of the
driver O, so that it shall drive the pegs either even with tlie surface of
the solc, or above or below that surface, as may be required or preferred:
The spiral spring S gives the downward impulse to the driver bar when
it is released from engagement with the block H attached to the rear
side of the cross head; J'is a bent arm T which performs sundry functions.
As the cross head rises and falls by means of a projection 6 it operates
the lever Y, attached to which is a pawl c, which impells the ratchet
wheel mon the top of the feed roll d by which the peg wood is fed into
the machine. By means of a pin V (sce Figure 3) it operates the slotted
lever Y which drives the feed 'sleeve or roll. It also serves to depress
the compresser bar B³. An ear c¹ on the face of the lever V engaging a
stud on the upper end of the compresser bar raises the said bar. The
said compresser bar is disposed within a case B' which is affixed to the
frame just in rear of the feed sleeve, as shewn in Figure 2. This com-
presser bar is so arranged as to intermittingly impinge against the spring.
retaining the peg wood, and so press the spring against the peg wood
as to condense the wood to any desired degree, the compression of the
'wood being effected, while the latter is stationary, the compresser being
retracted when the peg wood is fed along so as to produce no undue
friction thereon. B is the knife which is affixed to the lower end of
rocker arm o³ which is pivoted to a bar c', as shown in Figure 1. This
arm or lever has a curved slot c³ in which a stud d² from an arm'd³
affixed to the cross head works, and by which the knife receives its
reciprocating movement as the cross head J is reciprocated. This knife
is of a curved bent shape, and has its cutting edge disposed vertically,
and works within a slot formed in the plate G³, such knife in its move-
ment passing transversely across the peg wood passage, and severing a
peg from the peg wood at each forward movement of the knife. The knife
is made very thin at its edge or the part that enters the wood, while the
remainder is made thick enough to ensure the requisite rigidity. This
knife is so exactly fitted in its slot as to be incapable of the least lateral
vibration. The cut, therefore, is always in the same plane, and the
strip of peg wood in which it operates being firmly compressed and

page_text: rigidly and immovably fixed while the knife is passing through it, the
pegs severed from it are perfectly uniform in size and shape.
it
h
The pcg wood is inserted in its carrier in strips at the point as shown
in Figure 5. A spring presses it firmly against the roughened roller d
operated by the paul c and the adjustable brakel, and by this roller it'
is driven through a passage in the body of the axis of the sleeve till
emerges in the square hole in which the driver o works, see Figure 6.
The pcg wood is held down by a bar A¹ placed on top of it. The bar A
is adjustable and held in position by means of set screw c¹³, as shown in
Figures 1 and 6. The brake prevents the peg wood from slipping
backward when the pawl c is disengaged from the ratchet wheel m,
and while the knife is passing through the peg wood. The lever V has
a collar which embraces the rear portion of the feeding sleeve and
moves loosely on it. The slot in this lever is of the form as shown in
Figure 3, so that the latter part of the downward movement, of the
head J and bar T, and at the beginning of the upward movement the
lever V will be stationary, but will be raised at the last part of the
upward movement of the bar T and depressed at the beginning of
its downward movement. A pawl attached to the face of lever V
engages the ratchet W on the surface of the feed sleeve and moves
forward the sleeve the distance between two teeth at every oscillation
of the lever; the movement taking place after the peg hole has been
made and just before the peg is driven, the effect of the movement being
to bring the peg hole under the driver to receive the peg.

1. The feeding sleeve, sec Figures 1 and 5, is a hollow cylinder which
turns on a cylindrical axis Z projecting from the frame, the rear belt
of the cylinder or sleeve is smooth to engage the brake D¹, and to receive
the collar of lever V which freely moves on it as before obscrved. The
middle belt of its surface has the ratchet W cut upon it, and engages
with the pawl a on lever V to drive the feed sleeve by the move-
ment of the latter. The front part X of the surface of the sleeve is
roughened, so that, it will take hold of the sole of the boot or shoc, and
feed it; along by friction as the sleeve moves on its axis. To control
the movement of the feed sleeve and prevent its turning backward
when the pawl a is disengaged from the ratchet W, I employ a brake D³,
see Figures 1 and 5, which is made to press with greater or less force as
may be required against the rear belt of the surface of the feed sleeve
which it. partly embraces. The pressure of the brake is regulated by

page_text: the set screw E, which can be tightened or loosened as may be required.
On the front part of the axis Z are attached the plates F¹ and G₁ by:
means of screws; the two plates are grooved diametrically on their inner
faces as shown in Figures 11 and 12, so that when brought together.
and attached they form passages j, k, for the awl L and driver O. The
inner plate G¹ has an oblong opening in it to allow the exit of the peg
from the passage in the axis Z to the driver groove K. o', o', are two
adjustable plates which are affixed in recesses formed in
of the axis Z as shown in Figure 12. These plates form the front walls
of the peg wood 'passage and are made adjustable so as to compensate for
any wear occasioned by the friction of the peg wood, and enable them
to be maintained at their normal distance apart, so as to preserve the
peg wood in a rigid state for the action of the knife and in a direct line
with the slot through the cap G¹.
the front end
Figure 13 shows the device for shifting the position of the boot or
shoe so as to change the line of pegging without stopping the motion
of the machine. It requires to be used when a double row of pegs is to
be inserted. It consists of the slide S¹ having a shoulder or wheel »
on its front end and a toe p on its rear end, the slide being affixed to
a frame S which is screwed to the under side of the bed of the machine.
A spring S applied to the slider, and having one end resting against a
shoulder, while its other end rests against a projection 73 on the
frame S2, serves to retract the slider towards the rear of the machine:
It is driven forward by the beviled toe Ss affixed to the inner end of a
short arm projecting from the lever L'.. By depressing the lever L' the
beviled toe S3 is forced up behind the toc p and the slider S' is impelled
forward; the change effected in an instant by the simple touch of the
lever.
The mechanism for arresting the action of the machine is shown in
Figures 1 and 15. D' is the fly wheel, which is affixed to a sleeve p*
embracing the main driving shaft, and revolving freely thereon, such
sleeve also carrying the gear C. In order that the motion of the said
wheel may be imparted to the driving shaft a bar spring C² is affixed
to the end of the shaft, and engages
disposed on the face of the wheel, as
driving shaft being thus clutched to the
motion will be given to the said shaft. The mechanism for arresting
the action of the machine consists of the bent rocker lever L, which
with a beviled lug or ear es
shown in said Figures. The
wheel on rotation of the latter
J

page_text: is supported in arms a, a, depending from the frame. This lever has
one end of an arm as affixed to it, its other end is jointed to a pitman a
affixed to a foot treadle a suitably connected to the lower part of the
pedestal. The outer vertical edge of the rocker lever is formed with
an incline p*, as shown in Figure 16, which is a top view of the said
lover. When in operation the incline of this lever is brought into*
the path of revolution of the spring lever affixed to the end of the
main driving shaft, and as the maximum width of the incline is greater
than the width of the lug upon the wheel the spring bar entering
the incline, is thrown out of engagement with the lug, and the bar
is brought up against a shoulder o formed on the outer end of the
rocker, lever, as shown in Figures 1 and 16, by which the revolution'
of the shaft is instantaniously arrested. By the application of the
foot of the operator to the treadle connected with the rocker lever
the machine may be quickly stopped or set in motion.
The next part of my Invention to be described is the jack for
supporting the boot or shoe while being pegged, such part of my'
Invention being shown in Figures 1 and 14, wherein A¹³ denotes a'
vibratory last holder so applied to a plate B", and disposed at a right
angle therewith as to be capable of turning on a center pin as going
through the upper part of the plate. The said last holder has two
arms 63, 6, formed and projecting down from it in manner as repre-
sented in Figure 1. c³ is the toe rest, and d³ the heel support, which
consists of a bar or post e³ pivoted to the arm b³ near its top, and
so as to be capable of being moved toward and away from the toe
rest; the said bar carries a heel pin fs to enter a socket formed in
the heel of the last. To the lower end of the heel pin post a spring
pawl g³ is affixed, such engaging with a rack h³ made in the lower
part of the curved arm b³. By taking hold of the lower end of the
heel pin post and moving the same either forward or backward, the,
last may be either firmly secured to the jack or released therefrom as:
may be desirable.
The plate B is applied to one side of a rotary
standard C3 by means of three screws d, e, f, which go through,
curved slots g, h, , which go through the said plate, arranged with
reference to each other, as shown in Figure 14,. the two screws.d*.
and e, being at the upper part of the plate, while. the screw .i* is.
at its lower part, as represented. Each screw is screwed into the
standard. Each of the upper slots. has a curve, whose center is in
t
.
•

page_text: the axis of the screw which goes through the other slot. The lower
slot has a curve, which is struck from two centers, which are at the axis
of the two screws d', e. f is a lever, which is pivoted near one end
of the arm b', its other end carrying a stud, which works with a slotted
arm or loop h projecting from the front face of the plate B". The
object of this lever and its adjuncts is to determine the limit of longi.
tudinal vibration of the jack, and aid in maintaining it in a horizontal
position as well as to aid in preserving it in position when tipped. S³ is
a curved lever which is pivoted to the arm * and carries on its inner
end a shoulder 0%, which engages with a curved projection or toe o³,
which by means of a sleeve is screwed to a rod o extending from the
face of the plate B, the said sleeve being provided with a set. screw,
by which the toe may be adjusted in any desirable position. The
purpose of this last-described arrangement is to enable the operator to fix
his last in a desired fixed inclination, and maintain it in such position.
From the above description it will be seen that when the shoe last is
horizontal, transversely it will rest upon the two centers d', e', and will be
held in such position with much greater case and firmness than it would
be if it rested upon a single pivot disposed under the center of the
last, upon which it might be turned in either direction; but when in
pegging one side of a shoc it becomes necessary to turn the last so as
to direct the pegs more to the center of the shoe, it is obvious that the
arms b³, 6ª, must be swerved toward that side of the shoc which is being
pegged, and that the center or pivot on the opposite side will alone
support the last holder and shoe, and receive the force of the blows. It
is obvious too that as the last or shoe is raised from the center on the
side which is being pegged the force of the blows in pegging, and the
pressure between the jack and the pegging mechanism at the point
which is being pegged will tend to throw the shoe back upon that
center so long as the joint or pivot on which the shoe or last turns lics
on the opposite of a line drawn between the point which is being
pegged and that point of support of the jack standard, and that as both
of such forces act in the same direction the operator will easily resist
the tendency by pressing upon the arms 63, 64, and by such act maintain
the shoe in contact with the pegging mechanism. But if the pivot on
which the shoe or last turns passes by the line between the point which
is being pegged and the point of support of the jack standard, it is
equally obvious that the force of the blows and the pressure between the

page_text: jack and the pegging mechanism will tend to turn the shoe still more, and
that the operator must resist this tendency by pulling upon the arms b³, 64,
instead of pressing upon them, and that such pulling upon the arms
will have a tendency to pull the shoe away from the pegging mechanism.
It is further obvious that as the joint or pivot is about passing the line
between the pegging mechanism and the point of support of the jack
standard the position of the shoe is a very unstable one, and the operator
would be required to pull or push upon the arms 63, 64, in such a manner
that it be difficult to keep the shoe in the proper relation to the pegging
mechanism. But by placing the centers on which the jack turns at
some distance to one side of the line of the jack standard, the joint or
pivot on which the shoe turns will either not pass the line between the
pegging mechanism and the point of support of the jack standard at all,
or will pass it only at or near the extreem limit of the lateral movement
when the pin f approaches the end of its slot, when it furnishes a rigid
support. The placing of the pivots or joints on which the lateral
turning of the shoe takes place out of the line of the jack standard is
therefore one of great importance, as it gives far more perfect and easy
control of the jack, and at the same time greater stability.
