I, ELOUILD DUPLESSIS, of 46, Napoleon Street, of the City of St. Hyacinthe,
in the County of St. Hyacinthe, and Province of Quebec, Dominion
Canada, Machinist, do hereby declare the nature of this invention
to be as follows:-
My invention has for its object to so improve pegging machines that they will
do a better class of work and be more easily operated than has been possible
heretofore.
The invention may be said, briefly, to consist in improvements in the means
for cutting off the ends of the driven pegs, providing means whereby the said
ends may be caused to be either cut off flush with the surface of the work or
below the said surface for a variable distance.
To these ends, I mount in the nose of the horn of the machine, a rotatable
carrying part for the cutter, adapted to removably carry the said cutter, and
provide means for retaining the said cutter against displacement relatively to
its carrying part. Adjacent to this cutter, I provide a vertically adjustable
work-supporting section adapted to determine the position of the surface of the
work through which the pegs project relatively to the cutter, in order to enable
the pegs to be cut off flush with the said surface or projecting through the said
surface to a variable extent.
The perforating and peg-driving mechanism, and their carrying and operating
parts together with the frame of the head are and may be of any approved
construction and therefore will not be hereinafter further alluded to.
Specifically speaking, the nose of the horn is circular in form and horizontally
off-set, and provided concentrically thereof with a screw-threaded perforation.
A semicircular slot is cut vertically through this off-set portion, concentrically
of said screw-threaded perforation and in front thereof, and a circular recess
is cut concentrically of this slot, while the outer edge of the nose is upwardly
off-set to provide a flange which is screw-threaded on its outer side, and the
body of the horn is formed with a chamber extending far enough into the nose of
the horn to intersect the adjacent portion of the recess.
The cutter proper is mounted upon a carrying part consisting preferably of an
annulus having its upper edge angular in cross-section, and its lower portion
diminished in thickness to form a shoulder while its lower edge is formed with
bevelled gear teeth. This carrier is set with its lower toothed edge located within
the circular recess and with its shoulder resting upon the upper end of the
upwardly off-set flange, while the outer bevelled side thereof is formed with a
series of projections.
The cutter proper is in the form of a bevelled ring having its upper edge saw-
toothed and its lower edge notched and this cutter is adapted to be placed loosely
upon its carrier (the before mentioned annulus) with its notches receiving the
projections thereof. This cutter is retained against displacement by means of
a ring having its upper edge inwardly off-set, and the inside of its body portion

page_text: is screw-threaded to engage with the screw-threaded periphery of the nose of
the horn. This ring serves the double purpose of retaining the parts against
displacement and guarding the cutter against damage, and under certain circum-
stances it serves as an auxiliary adjustable work-support.
The means for regulating the extent to which the ends of the driven pegs are
to project through the surface of the, work after having been trimmed, consists
preferably of a vertically adjustable work-supporting section located within and
concentrically of the cutter, and is adjusted by means of a screw-threaded shank,
formed integrally therewith and adapted to take into the screw-threaded per-
foration in the nose of the horn, the lower end of this shank being slotted to
receive the end of a screw-driver, or the like, through which the vertical adjust-
ment of this central work-supporting section is secured.
The cutter carrier is driven by means of a spindle extending longitudinally
through the chamber, in the horn of the machine, and having a bevelled gear
mounted rigidly upon the upper end thereof and adapted to intermesh with the
bevelled teeth of the said carrier, while the lower end of this spindle is screw-
threaded and projects through a bushing and. has a pinion screwed thereon to
which a rotary movement may be imparted from any desired initial power.
In some classes of work, as for instance when the insole used is thin or frail,
it is desirable, when trimming the pegs, to leave a small portion projecting beyond
the surface, in order to be spread and thus enable the parts to be better held
together thereby. This is accomplished by adjusting either the central work-
supporting section, alone, or with it the encircling adjustable ring, a distance
above the teeth of the saw equal to the length it is required that the peg shall
project.
The slot in the nose of the horn allows an exceedingly long awl to be used,
thus enabling stock of different thickness to be operated upon, as in the case of a
thin stock the awl will project therethrough and into the said slot, while stock
of a thickness equal to the length of the awl may be as readily used.

Improvements in Pegging Machines.
I, ELOUILD DUPLESSIS, of 46, Napoleon Street, in the City of St. Hyacinthe,
County of St. Hyacinthe, and Province of Quebec, Dominion of Canada,
Machinist, 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 has for its object to so improve pegging machines that they will
do a better class of work and be more easily operated than has been possible
heretofore.
The invention may be said, briefly, to consist in improvements in the means
for cutting off the ends of the driven pegs, providing means whereby the said
ends may be caused to be either cut off flush with the surface of the work or
below the said surface for a variable distance.
To these ends, I mount in the nose of the horn of the machine, a rotatable
carrying part for the cutter, adapted to removably carry the said cutter, and
provide means for retaining the said cutter against displacement relatively to
its carrying part. Adjacent to this cutter, I provide a vertically adjustable

page_text: work-supporting section adapted to determine the position of the surface of the
work through which the pegs project, relatively to the cutter, in order to enable
the pegs to be cut off flush with the said surface or projecting through the said
surface to a variable extent.
I will proceed to describe my invention with reference to the accompanying
drawings forming a part of this specification in which like symbols indicate the
same parts, and wherein,
Fig. 1 is an enlarged detail longitudinal vertical sectional view of the nose of
the horn constructed according to my invention.
Fig. 2 is a detail plan view thereof.
Fig. 3 is a similar view, but with the annulus for retaining the parts against
displacement, removed;
Fig. 4 is a similar view to Fig. 3, but with the cutter removed.
Fig. 5 is a similar view to Fig. 4, but with the carrier for the cutter and the
central adjustable work supporting portion, removed.
The perforating and peg driving mechanism, and their carrying and operating
parts together with the frame of the head may be of any approved
construction and therefore will not be hereinafter further alluded to.
The nose of the horn is preferably circular in form and horizontally off-set
as at 16, and provided concentrically with a screw-threaded perforation 17. A
semi-circular slot 18 is cut vertically through this off-set portion concentrically
with the said perforation 17 and in front thereof, and a circular recess, 19, is
cut concentrically with this slot, while the outer edge of the nose is upwardly
off-set to provide a flange 20, which is screw-threaded on its outer side.
The body of the horn is formed with a chamber 21 extending far enough into
the nose of the horn to intersect, as at 22, Fig. 5, the adjacent portion of the
recess 19.
The cutter proper is mounted upon a carrying part consisting preferably of an
annulus 23, having its upper edge angular in cross-section and its lower portion
diminished in thickness to form a shoulder at 24, while its lower edge is formed
with bevilled gear teeth 25. This carrier is set with its lower toothed edge
located within the recess 19, and with its shoulder 24, resting upon the upper
end of the flange 20, while the outer bevilled side thereof is formed with a
series of projections 26.
The cutter proper is in the form of a bevilled ring 27 having its upper edge
saw-toothed, as at 28, and its lower edge notched, as at 29, and this cutter is
adapted to be placed loosely upon its carrier, 23, with its notches 29, receiving the
projections 26, and it is retained against displacement by means of a ring 30,
having its upper edge inwardly off-set, as at 31, and the inside of its body portion
screw-threaded to screw upon the screw threaded periphery of the nose of the horn.
This ring serves the double purpose of retaining the parts against displacement
and guarding the cutter against damage, and under certain circumstances it may
serve as an auxiliary adjustable work support, as will be hereinafter set
forth.
The means for regulating the length the ends of the driven pegs are to
project through the surface of the work after having been trimmed, consists
preferably of a vertically adjustable work supporting piece 32 located within and
concentrically of the cutter and it is adjusted by means of a screw-threaded
shank 33, formed integrally therewith and adapted to screw into the screw-
threaded perforation 17 in the nose of the horn, the lower end of this shank
being slotted as at 34, to receive the end of a screw driver, or the like, through
which the vertical adjustment of this work-supporting piece is secured.
If desired, this regulation of the length of the protruding ends of the diven
pegs can be made more uniform and more effective by utilising the ring 30, for
that purpose by adjusting same through its screw threads to the same level as
the surface of the work-supporting piece 32.
The cutter carrier 23 is driven by means of a spindle 40, extending longi-

page_text: tudinally through the chamber 21, in the horn and having a bevelled pinion 41,
mounted rigidly upon the upper end thereof and adapted to gear with the bevelled
teeth 25, of the said carrier while the lower end of this spindle is screw-threaded
and projects through a bushing, 43, and has a pinion 44 screwed thereon to
which a rotary movement may be imparted from any desired initial power, not
shewn.
In some classes of work, as for instance when the insole used is thin or frail,
it is desirable, when trimming the pegs, to leave a small portion projecting
beyond the surface, to be spread and enable the parts to be better held together
thereby. This is accomplished by adjusting the work-supporting piece 32, a
distance above the teeth of the saw equal to the length it is required that the
peg shall project.
The slot 18 in the nose of the horn allows an exceedingly long awl to be
used, thus enabling stock of different thickness to be operated upon, as in the
case of a thin stock, the awl will project therethrough and into said slot, while
stock of a thickness equal to the length of the awl may be as readily used.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a pegging machine, the combination with a cutter, of vertically adjust-
able work-supporting mechanism located with a part on each side of said cutter
and adapted to adjust the work to and from the cutter, substantially as and for
the purpose set forth.
2. In a pegging machine, the combination with a rotary cutter consisting of
a ring saw-toothed on its inner edge, a vertically adjustable work supporting
