WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN AND RELATING TO PEGGING
MACHINERY CHIEFLY DESIGNED TO BE USED IN THE MANUFACTURE OF BOOTS
AND SHOES." [A communication from abroad by George W. Copeland, of Malden,
and William Storey Eaton, of Boston, both of Massachusetts, United States of
America.]
This Invention relates to pegging machinery, chiefly designed to be used in the'
manufacture of boots and shoes, and adapted to be moved and placed for each peg
driven; also to mechanism for automatically disengaging the driving pulley from
the peg driving mechanism after the driving of each peg, and to means for
suspending the pegging mechanism to provide it with universal adjustability in
relation to the work support.
The said Invention is particularly adaptable for use in the process of uniting the
uppers of boots and shoes to the insole in the lasting process.
In carrying the said Invention into practice the driven pulley has a bearing on a
shaft, and a movement thereon to and from a cam disc with which it has a clutch
connection. It is provided with a V-shaped recess the upper wall of which is
adapted to engage with the upper side of a projection on the cam disc. The pulley
is provided with a hub extension, which is laid hold of by a clutch-lever pivoted
to the frame of the machine and straddling the hub, and connected therewith by
pivots which enter a circumferential recess therein; a spring extending from the
edge of the frame to the end of this lever serves to keep the clutch in contact with
the cam when it is not held therefrom by mechanism bereinafter described.

page_text: The said disc is fastened to the end of the aforesaid shaft; it is provided with
an edge cam which operates the transferring mechanism, and a cam pin which
actuates a slotted cross-head to which an awl supporting bar and a rod carrying a
peg severing knife are attached. The cam pin also lifts a driving bar carrying a
driver by contact with an extension, which projects from the driving rod into the
upward path of the cam pin, and against the tension of the driving spring which
surrounds the driving rod, and bears against an adjusting nut upon a standard and
a shoulder on the driving bar. The said crosshead is rigidly fastened to the awl-
driving bar by studs, and the awl driving bar is reciprocated vertically in the
standard parallel with the inner wall of the standard on one side, and with the
driving bar on the other. The said edge cam operates through a rock lever which
lays hold of a projection, it moves the standard laterally sufficiently to cause the
transfer of the awl and driver after the requisite interval. The frame of the
machine is provided with a downwardly projecting portion to which a bracket
carrying a throat is adjustably secured by means of a slot and set screws. Attached
to the lower end of the standard is a bracket containing a feedway. This feedway
opens into the driveway in which the peg driver reciprocates.
The feeding mechanism consists in a corrugated feed wheel which is arranged to
project into the feedway from the inner side, and is intermittently revolved by
means of a pinion and pawl. An adjustable presser is arranged opposite the
feed-wheel, and holds the peg-strip against it with sufficient force to ensure its
feeding.
A knife is fastened to a head having suitable bearings in a block, and is
reciprocated by a rod across the feedway. The aforesaid shaft is provided with
suitable bearing in the frame, and carries at its end a disc provided with face and
edge cams which operates the mechanism for disengaging the driving pulley from
the cam disc after the driving of each peg, and also a device for lifting the driving
bar immediately before the transfer of the awl for the purpose of relieving the
throat and other parts against which the driving rod bears, from the stress of the
driving spring while the transfer is taking place. A catch projects through a slot
of the same width in the aforesaid clutch lever, and is provided with a vertical
movement in relation to a latch. It is fastened to a plate which is arranged to
engage with a projection on the end of a rod in a handle. This rod is depressed
against the action of a spring which surrounds the same, and it is provided with a
thumb piece. Another spring serves to keep the plate in contact with the pro-
jection; the latch is provided with a horizontal movement in a block by means of
the face cam, against which a piece projecting downwardly from the latch bar
contacts. A spring maintains the contact betwen the cam and the said piece. This
cam serves to disengage the pulley from the driving cam disc after the driving of
the peg by causing a latch to move away from the pulley, thereby moving the
clutch lever in the same direction, and causing it to move the driven pulley away
from the cam disc.
This allows the pulley to revolve freely until the clutch on its side again engages
with the cam disc; and this is effected by tripping the catch and allowing the
spring to draw the clutch lever towards the pulley, thereby causing the pulley
clutch to engage with the cam disc. After the latch is tripped or returned to a
position to again engage with the catch, it remains stationary until the descent of the
driving rod, when the can causes it to disengage the driven pulley in the manner
indicated.
An edge cam operates through a rock lever which engages with a projection
upon the side of the driving bar, and serves to lift the same preparatory to the
transfer of the awl and driving mechanism in relation to the stationary throat.
The standard which supports the awl-carrying bar, the driving, bar, and the feed
severing devices is pivoted to one arm of a yoke, and the other arm of the yoke
lays hold of and furnishes a bearing for the shaft just beyond its bearing in the
frame. A bracket is fastened to the frame and supports a handle, as well as the
pawl actuating the pinion on the feed-wheel shaft. A spring is.fastened to the end

page_text: of this bracket and to the lower end of the standard, and it serves to keep the first
named rock lever in contact with its actuating cam, and moves the end of the
standard, and the mechanism held thereby in effecting the transfer when the
shoulder on the operating cam has passed beyond the end of the lever:
The yoke is provided with a rod which is surrounded by a sleeve upon a tilting
bar and swivels therein. The tilting bar is arranged to straddle a pulley and is
provided with a pivoted bearing on the shaft supporting the said pulley, and it
carries at its opposite end an adjustable counterbalance, and a reel carrying the
peg-strip. A hanger supports a shaft and is connected by a rod and hanger, or by
a gimbal joint to a countershaft. This shaft is supported by brackets fastened to
any sufficient support, and carrying a driving pulley. Power is communicated to
the machine by means of belts extending from the driving pulley to an intermediary.
pulley, and from thence to the driven pulley.
The supporting rod is arranged to swivel in its hanger. When not in use the
machine may be moved away from its work, and is supported by the mechanism
provided for the purpose. By this suspending mechanism the pegging machine is
provided with every necessary adjustment in relation to the last or other work
support.

A is the driven pulley which has a bearing on the shaft a, and a movement
thereon to and from the cam disc B with which it has a clutch connection. It is
provided with a V-shaped recess a', the outer wall of which is adapted to engage
with the outerside of the projection 6 on the cam disc B. The pulley is provided
with a hub extension a³, which is laid hold of by the clutch lever C pivoted at c
to the frame D of the machine and straddling the hub, and connected therewith by
the pivots c¹ which enter a circumferential recess therein; a spring c² extending
from the edge of the frame to the end of this lever serves to keep the pulley or
clutch in contact with the cam, when it is not held therefrom by mechanism
hereinafter described.
The disc B is fastened to the end of the shaft a, and is provided with the edge
cam which operates the transferring mechanism, and the cam pin 63 which
actuates the slotted cross head 63 to which the awl supporting barb, and the rod 65
carrying the peg-severing knife are attached. The cam pin b also lifts the driving
bar E carrying the driver e by contact with the extension E³, which projects from
the driving rod into the upward path of the cam pin, and against the tension of
the driving spring which surrounds the driving rod, and bears against the adjusting
nut e upon the standard e³, and the shoulder e on the driving bar.
The cross
head 6 is rigidly fastened to the awl-driving bar by the studs 66, and the awl-
driving bar is reciprocated vertically in the standard e³ parallel with the inner wall
of the standard on one side, and with the driving bar on the other. The edge cam
b¹ operates through the rocking lever F which embraces the projection e³, and the
said cam moves the standard e³ laterally sufficiently to cause the transfer of the awl

page_text: and driver after, the requisite interval. The frame D is provided with a down-
wardly projecting portion d to which the bracket g carrying the throat G is
adjustably secured by means of the slot g¹, and set screws g². Attached to the
lower end of the standard e³ is the bracket e containing the feed way H. This
feed-way opens into the drive way in which the peg driver e reciprocates. The
feeding mechanism consists in a corrugated feed wheel h which is arranged to
project into the feed way from the inner side, and is intermittently revolved by
means of the pinion.h' and pawl h². The adjustable presser h³ is arranged opposite
the feed-wheel, and holds the peg-strip against it with sufficient force to ensure its
feeding.
The knife M is fastened to the head m, having suitable bearings in the block m',
and is reciprocated by the rod b³ across the feed-way. The shaft a is provided with
a suitable bearing in the frame D, and carries at its end the disc N provided with
face and edge cams, which operate the mechanism for disengaging the driven pulley
from the cam disc B after the driving of each peg, and also a device for lifting the
driving bar immediately before the transfer of the awl, for the purpose of relieving
the throat and other parts against which the driving rod bears, from the stress of
the driving spring while the transfer is taking place; o is a catch which projects
through a slot of the same width in the lever C, and is provided with a vertical
movement in relation to the latch o¹. It is fastened to the plate o³ which is
arranged to engage with the projection o³ on the end of the rod in the handle P.
This rod is depressed against the action of the spring of which surrounds the
same, and it is provided with the thumb piece oº. A spring o7 serves to keep the
plate o in contact with the projection o³; the latch o' is provided with a horizontal
movement in the block o by means of the face cam N, against which the piece 010
projecting downwardly from the latch bar rests. A spring o maintains the
contact between the cam and the piece o¹º. This cam serves to disengage the
pulley from the driving cam disc B after the driving of said peg, by causing
the latch o¹ to move away from the pulley A, thereby moving the clutch lever C
in the same direction, and causing it to move the driven pulley away from the cam
disc. This movement' allows the pulley to revolve freely until the clutch again
engages with the cam disc, which engagement is effected by tripping the catch and
allowing the spring c³ to draw the clutch lever towards the pulley, thereby causing
the pulley clutch to engage with the cam disc B. After the latch is tripped or
returned by the spring o¹ to a position to again engage with the catch, it remains
stationary until the descent of the driving rod, when the cam causes it to disengage
the driven pulley in the manner indicated.
The edge cam n¹ operates through the rocking lever R a lever which engages
with a projection e' upon the side of the driving bar, and serves to lift the same
preparatory to the transfer of the awl and driving mechanism in relation to the
stationary throat..
The standard es which supports the awl carrying bar, the driving bar, and the
feed severing devices is pivoted at es, to one arm of the yoke S, and the other
arm of the yoke lays hold of and furnishes a bearing for the shaft a just beyond
its bearing in the frame D. A bracket d' is fastened to the frame D, and supports
the handle Pl, as well as the pawi actuating the pinion on the feed-wheel shaft.
A spring is fastened to the end of this bracket and to the lower end of a
standard, and serves to keep the lever F in contact with its actuating cam, and
moves the end of the said standard and the mechanism held thereby in effecting
the transfer when the shoulder 67 on the operating cam b' has passed beyond the
end of the lever.
The yoke S is provided with a rod 8 which is surrounded by the sleeve 8¹ upon
the tilting bar &², and swivels therein.
The said tilting bar så is arranged to straddle the pulley t, and is provided
with a pivoted bearing on the shaft supporting the said pulley, and it carries at
its opposite end the adjustable counterbalance S', and the reel S³ carrying the
peg-strip. The hanger & supports the shaft t¹ and is connected by the rod to and

page_text: .
•hanger t, or by a gimbal joint to the countershaft t2. This shaft is supported by
the brackets fastened to any suitable support, and carries the driving pulley t*.
Power is communicated to the machine by means of. belts extending from the
driving pulley to the intermediary pulley t, and from thence to the driven
pulley A.
The supporting rod to is arranged to swivel in its hanger t. When not in
use, the machine may be moved away from its work and supported by the
mechanism shown in Figure 1. By this suspending mechanism the pegging
machine is provided with every necessary adjustment in relation to the last or
other work support. To operate the machine the handle P¹ is held in the left
hand, and the handle P by the right hand with the thumb bearing upon the
thumb piece. The machine is then placed in position with its throat resting upon
the spot where the peg is to be driven. The thumb piece is then depressed,
thereby operating the tripping mechanism and allowing the driven pulley to engage
with the driving cam disc. The awl is then driven and a peg severed and fed. As
the awl bar is lifted, the driving bar is also raised against the driving spring until
the cam pin having revolved sufficiently releases the same, and allows the spring to
operate the driver. Immediately before the driving rod descends, the transfer of
the drive way to the position occupied by the awl in line with the throat is effected
in the manner indicated, and by this movement the spur wheel is revolved
Bufficiently to feed the peg strip a necessary distance by its movement in relation
to the pawl which is stationarily supported.. Immediately before the descent of
the awl, the transferring mechanism automatically moves the awl to its original
position in the manner indicated.
Having thus fully described the said Invention as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it understood
that what I consider to be the important features of this Invention are as follows,
that is to say :-
First. A construction of the parts whereby the driven pulley A can be auto-
matically disengaged from the cams, operating the awl, peg driver, severing,
feeding, and transferring mechanism immediately after the driving of each peg.
Second. The means whereby the pulley A is restrained from communicating power
to the peg-driving mechanism until released by a suitable tripping mechanism.
Third. The means for connecting the said pulley with the peg driving mechanism
upon the release of the said restraining devices.
Fourth. The means for suspending or supporting the mecbanism for driving pegs
by power, so that it shall have universal adjustment in relation to the work
support or last.
Fifth. Counterbalancing the pegging mechanism so that very little of its weight
is lifted by the operator in moving it in relation to the work.
Sixth. The combination of parts comprising the mechanism for driving the pegs,
and for supporting this mechanism.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Sixteenth day of February, in the year of our Lord One
thousand eight hundred and eighty.
