Improvements in Lip Turning and Slitting Machines Employed in
Boot and Shoe Manufacture.
A communication from abroad by JOHN BENJAMIN HADAWAY, of Brockton, in the
State of Massachusetts, one of the United States of America, Engineer.
I, ALFRED GEORGE BROOKES, of 55 and 56, Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
to be as follows:
The present invention relates to sole machines employed in the manufacture of
boots and shoes and more particularly to a machine for turning up and setting the
lip of a "lipped" insole, such machines being generally known in the art as lip
turning machines..
The present invention has for its object to produce a machine of this character
which will expeditiously turn up and set the lip, imparting thereto the desired
angular set relatively to the surface of the sole, and arranged to act upon the
lip in such manner that the fibres of the leather of which the lip is composed
and more particularly at the angle between the lip and feather, will be pounded
and compacted, whereby said lip will retain the augular position to which it has
been set relatively to the surface of the sole.
The present invention therefore consists of the lip turning machine which will
be hereinafter described.
A supporting frame, of suitable size and shape to support the working parts,
is used which may be conveniently provided with legs or standards which rest
upon a bench or other support in convenient reach of the operator.
Upon the top of the frame are the upwardly projecting standards which may be
secured thereto or cast integrally therewith, said standards being provided with
suitable bearings for the driving shaft.
Upon one end of the driving shaft, is a driving pulley and a suitable clutch
whereby said shaft may be rotated to actuate the moving parts of the machine,
and its rotation controlled by the operator.
A rotating work support is provided which is carried at the upper end of a short
shaft, which is mounted in a bearing, carried by an elbow extending from the
tubular bearing which is affixed to the front of the machine in any suitable manner
as by a bolt.
The said short shaft extends through a gear, said gear being splined to said
shaft, whereby rotary motion is imparted to the work support and whereby said
work support may have a vertical movement towards and from the lip setting
tool.
As is common in work supports of this character, the work support is raised
by a spring which is contained in the tubular bearing said spring acting against
the short shaft, and said work support is arranged to be drawn down against the

page_text: tension of the spring by a rod which is connected with the said short shaft in any
suitable manner which will permit the rotation of said shaft.
A feed wheel is mounted upon the end of an inclined shaft which rotates in a
bearing formed upon an arm which is projected from a yoke, which extends for-
wardly from the standards, the feed wheel being at such an inclination relatively
to the work support that when the insole is superimposed upon the top of the work
support, the feed wheel will fit into the angle between the lip and feather, and
bear upon the feather which will be forced up by the upward movement of the work
support against the underside of the feed wheel.
The work support and the feed wheel are rotated in opposite directions by a worm
upon the main shaft which meshes with a worm gear upon the inclined shaft and
said inclined shaft carries a bevel gear which meshes with the bevel gear which is
splined to the work support shaft.
A rotation of the main shaft will by means of the worm, worm gear, and bevel
gears impart a simultaneous rotation to the feed wheel and work support in
opposite directions, to feed the work along the lip turning and setting tools, to bring
successive portions of the lip of the insoles under the action of said tools.
If desired the upper surface of the work support and the under side of the feed
wheel may be roughened or serrated to insure a better hold upon the work and a
more positive feeding thereof.
A plough or lip turning tool which consists of a forwardly projecting curved
finger carried by a bracket which is mounted upon some fixed portion of the
machine frame, as by a set screw passing through a slot into the bearing, may be
employed: The said plough is curved to conform to, and is adjusted to closely
approximate the periphery of the feed wheel, so that it will enter between the lip
and feather of the insole and as said insole is fed along between the feed wheel
and work support the plough will turn up the lip to be acted upon by the lip
setting tool.
It will be observed that the plough and the feed wheel act in the angle between
the lip and the feather and gauge and position the insole as it is fed along, relatively
to the lip setting tool.
A lip setting tool as the sole is fed along acts to impart the proper set to the lip
of the sole, or to fix it in the position, to which it has been raised by the plough.
For this purpose the lip setting tool is arranged to impart to the fibres of the lip
and more particularly to the base of said lip, short sharp and quick blows delivered
in rapid succession, whereby the fibres of the lip are compacted and the lip made
to retain the desired position to which it has been placed relatively to the surface
of the sole.
To secure the above suggested result in the machine, the lip setting tool is or
may be arranged to be reciprocated toward and from the edge of the sole upon the
work support, and preferably in an inclined direction so that the tool may act
upon the lip at its base.
For this purpose the lip setting tool is mounted upon the end of a slide which is
arranged to reciprocate in an inclined guide way formed upon the yoke, said guide
way being so inclined that the plane of reciprocation of the slide and the lip
setting tool will be substantially parallel to the upper surface of the feed wheel.
The slide is held in position in the guide way, by a plate, which is secured to said
guide way, in any suitable manner as by screws. The reciprocations of the slide
carrying the lip setting tool may be imparted thereto by any suitable mechanism,
such as a link, pivotally connected to said slide and at its other end pivotally con-
nected to one end of a shaft in the upper end of a lever fulcrumed upon a shaft,
said shaft being mounted in bearings in the ends of upwardly projecting extensions
of the standards. The lower end of the lever is forked and engages an eccentric
upon the main or driving shaft. A rotation of said shaft, will by means of the
eccentric oscillate a lever, upon its fulcrum, and by means of a link impart a
reciprocation to the slide and the lip setting tool, carried thereby, causing said
tool to act upon the lip and impart thereto the desired set. The said lip setting

page_text: tool is preferably shaped so as to have a working end which is angularly disposed
relatively to the shank and is removably secured to the slide by a screw which
passes through a slot formed in said shank, whereby said lip setting tool may be
adjusted longitudinally upon the slide carrying it. The working face of the said
tool may be shaped so as to have a substantially straight vertical face to cause the
lip to be set vertically at a substantial right angle to the surface of the sole, or
the working end of said tool may be shaped to lay over and turn down the lip
in a plane substantially parallel with the face of the insole, and in practice it
is the intention to provide a number of lip setting tools having various shapes
of working face suitable to position the lip in any manner desired for particular
work.
While the machine as herein before described constitutes a practical and operative
lip turning machine which will turn up and set the lip of the sole in the desired
position relatively to the surface of the sole, the thrust of the lip setting tool
against the sole would have a tendency to push the sole off of the work support and
said sole must be constantly held against the lip turner and the feed wheel with
some force by the operator.
In order to hold the insole in position upon the work support and to withstand
the thrust of the lip setting tool against the lip of the insole, the machine is pre-
ferably provided with a presser foot which is arranged to grip the insole within
the lip, and force the same down against the surface of the work support thus
clamping the same at the time the lip setting tool comes in contact with the lip.
The presser foot is formed upon the lower end of a rod or stem which is mounted
loosely in a vertical bearing and prevented from turning therein by any suitable
means such as a pin engaging a slot in said bearing.
The presser foot is arranged to be moved toward and from the surface of the work
support to alternately clamp and release the sole thereon, and such movement may
conveniently be secured by the following mechanism. The bearing is secured to
the forwardly extending arm of a three arm lever, the lower arm of which is forked
or yoke shape, and fulcrumed loosely upon a shaft mounted in a bearing carried
by the yoke of the fixed frame; the other arm of the three-armed lever being
pivottally connected by a stud to a link, which in turn is pivottally connected to
one end of the rod carried by the lever, the other end of the rod being connected
to the link which actuates the slide and lip setting tool as before described.
It will thus be seen that the presser foot and the lip setting tool are actuated
by connected mechanism and move at substantially the same time towards and from
the sole upon the work support.
The presser foot is so positioned that its lower end engages and clamps the work
just before the lip setting tool acts upon the lip, so that when said tool delivers its
blow upon the lip the sole will be firmly held by the presser foot.
The presser foot is arranged to yield vertically in its bearing to accommodate
for inequalities in the thickness of the insole and for different thicknesses of
insoles and at its upper end is acted upon by a spring which has a slot which
engages a head formed upon a screw which is tapped into a threaded bearing in the
end of the stem and the opposite end of the spring is secured by a screw to a boss
formed on the three arm lever.
In order to provide for a horizontal adjustment of the presser foot toward and
from the lip setting tool to provide for different thicknesses of lips, the bearing is
provided with a bracket, having a slot through which passes a set screw, by means
of which the bearing is adjustably secured to the arm of the lever. By loosening the
set screw the bracket may be moved in and out upon the arm thus moving the
bearing and the presser foot, the slot in the spring permitting a movement of the
head of the screw during such adjustment.
By lifting the spring and turning the screw the tension of the spring may
be adjusted.
In order to accurately adjust the relative times of contact of the presser foot
and the lip setting tool with the work, to secure the best results, the stud which

page_text: connects the arm with the link is an eccentric stud which may be turned to
secure adjustment.
A constant rotation is imparted to the feed wheel and work support to feed the
insole, and in order that the contact of the presser foot with the insole, and the
clamping action exerted thereon during the instant that the presser foot is in
contact with the insole, may not retard the feeding movement thereof, the presser
foot is arranged to have a slight lateral movement with the sole, which is provided
for by mounting the said three armed lever loosely upon the shaft and providing
for a slight lateral play of said lever upon said shaft, and also providing for a
lateral movement of the lower arm of said lever upon the said pivot stud.
spring secured at one end to a stud upon a fixed portion of the frame, and at its
opposite end to a stud projected from one arm or member of the yoked end of the
said three armed lever acts to hold said lever and presser foot in their normal
position, and to return them to such position, from the position to which they may
have been moved by the contact of the presser foot with the insole.
A
In practice the end of the presser foot may engage and clamp the innersole at a
point in line with the line of movement of the lip setting tool, and thus form an
abutment against which said lip setting tool may press the lip, or said presser foot
may be set slightly to one side of the line of movement of the lip setting tool, and
act merely to clamp the insole against the work support during the action of the
lip setting tool thereon, in either case the presser foot is found to be a desirable
feature of the machine, inasmuch as it relieves the operator of the strain necessary
to hold the insole in position against the pounding action of the lip setting tool.
In the operation of the machine, the insole which has been previously cut
or slit around its edge, is placed in position upon the work support with the lip
turner and edge of the feed wheel inserted in the slit, the upper flap formed by
said slit being the "lip" of the insole, resting against the lip turner or plough
and the under flap forming the "feather" of such insole resting beneath the feed
wheel and lip turner or plough, the work support rising under the action of its
spring and causing the feather of the insole to be gripped between the upper surface
of the work support and the feed wheel.
A rotation of the main shaft now causes a rotation of the work support and feed
wheel, and feeds the insole, causing the plough or lip turner to turn up or raise
the lip" which is acted upon, and given a series of rapid blows by the lip setting
tool, to set or shape the same, as has been fully described.
The lip turner or plough may be constructed so as to have the bracket and
the lip turner or plough with a cut away portion upon its under surface forming
a flange to overlic a portion of the periphery of the feed wheel, the upper
surface of the plough being rounded and bevelled off whereby said plough will
cause the lip of the insole to be gradually raised and turned up for the action
of the lip setting tool thereon.
In a modified form of the machine the lip setting tool carries a knife which is
arranged to slit the upper edge of the lip and thereby facilitate the setting of the
lip in the position desired by relieving the strain on the fibres of the lip caused
by bending it up in a curved line, and furthermore produced a much more flexible
insole than one in which the lip is not slit.
In this modified form referred to the lip setting tool is arranged to lay the lip
over upon the surface of the insole and it is therefore somewhat differently shaped
at its working end than the lip setting tool hereinbefore described; it having
in this instance a forwardly projecting tapering toe which is arranged to press
the lip of the insole down upon the surface of the sole.
Adjustably secured in a slot of the lip setting tool is a knife which is fastened
in place in said slot by means of a screw the said knife being inclined downwardly
and having its cutting edge at a point slightly back of the tapering toe of the lip
setting tool.
The presser foot of the machine according to a modification has no sidewise
movement as in the first described form of this machine, and its vertical movements

page_text: are in vertical alignment with the knife and said presser foot has upon its rear face
a groove or seat into which the cutting edge of the knife is arranged to be
received when making the cut so that said edge will not become dulled by striking
against a hard metallic surface.
Located adjacent to the lip setting tool is a lip pressing tool which has an
undercut projection at its forward end arranged to act upon and press the lip
after the lip has been turned over and slit by the lip setting tool and the knife
carried thereby.
The lip pressing tool is adjustably secured by means of the set screw and slot to
a fixed portion of the machine. In this modified construction of machine the
plough or lip turner is carried by a bracket which by means of the bolt and slot is
adjustably secured for a vertical adjustment to the bearing of the feed wheel.
The other parts of the machine may be the same except as above noted and
operate in the same way. By the arrangement of machine as last described the
lip of the insole will be slit or cut along its upper edge at each reciprocation of the
lip setting tool and after it leaves said tool as the sole is fed along by the feed
wheel the lip will be brought beneath the lip pressing tool and pressed and set
in the desired position.
By slitting the lip and pressing it as described it is caused to more readily
assume the desired position and besides the insole will be more flexible than a
sole with an unslitted lip and therefore preferred in some shoes.

Improvements in Lip Turning and Slitting Machines Employed in
Boot and Shoe Manufacture.
A communication from abroad by JOHN BENJAMIN HADAWAY, of Brockton, in the.
State of Massachusetts, one of the United States of America, Engineer.
I, ALFRED GEORGE BROOKES, of 55 and 56, Chancery Lane, in the County of
London, Chartered Patent Agent, 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:-
The present invention relates to sole machines and more particularly to a machine
for turning up and setting the "lip" of a lipped insole, such machines being
generally known in the art as lip turning machines.
The present invention has for its object to produce a machine of this character
which will expeditiously turn up and set the lip, imparting thereto the desired
angular set relatively to the surface of the sole, and arranged to act upon the
lip in such manner that the fibers of the leather of which the lip is composed
and more particularly at the angle between the lip and feather, will be pounded
and compacted, whereby said lip will retain the angular position to which it has
been set relatively to the surface of the sole.
The present invention therefore consists of the lip turning machine which will
be hereinafter described and particularly pointed out in the claims.
The present invention is illustrated in the accompanying drawings, in which
Fig. 1 represents the machine in side elevation with the driving pulley removed.
Fig. 2 represents a top plan view of the machine.

tool.
Figures 5 and 6 show a modified form of plow or lip turner.
Fig. 6 shows in right side elevation a portion of the machine modified by
providing the lip setting tool with a lip slitting knife and containing a presser to
act on the lip as it leaves the lip setting tool.

Presser.
Fig. 9 shows a bottom plan view of the plow or lip turner.
Fig. 10 shows in front elevation portions of the machine.
Similar letters of reference designate corresponding parts throughout the several
views.
In the drawing A represents a supporting frame, of suitable size and shape to
support the working parts, which may be conveniently provided with legs or
standards a, which rest upon a bench or other support in convenient reach of the
operator.
Upon the top of the frame A, are the upwardly projecting standards a¹ which
may be secured thereto or cast integrally therewith, said standards a¹ being pro-
vided with suitable bearings a³ for the driving shaft B.
Upon one end of the driving shaft B, is a driving pulley 6 and a suitable clutch b
whereby said shaft may be rotated to actuate the moving parts of the machine, and
its rotation controlled by the operator.
C represents a rotating work support which is carried at the upper end of a
short shaft c, which is mounted in a bearing c¹, carried by an elbow extending
from the tubular bearing, which is affixed to the front of the machine in any
suitable manner, as by the bolt c¹.
The shaft e extends through a gear, said gear being splined to said shaft,
whereby rotary motion is imparted to the work support C, and whereby said work
support may have a vertical movement towards and from the lip setting tool.
As is common in work supports of this character, the work support C is raised
by a spring (not shown) which is contained in the tubular bearing, said spring
acting against the short shaft e and said work support is arranged to be drawn down
against the tension of the spring by a rod c, which is connected with the shaft c in
any suitable manner which will permit the rotation of said shaft.
1) represents a feed wheel which is mounted upon the end of an inclined shaft d,
which rotates in a bearing formed upon an arm which is projected from a
yoke, which extends forwardly from the standards 'a', the feed wheel D being
at such an inclination relatively to the work support C, that when the insole is
superimposed upon the top of the work support, the feed wheel I) will fit into
the angle between the lip and feather, and bear upon the feather which will be
forced up by the upward movement of the work support C against the under side
of the feed wheel D.
The work support C and the feed wheel D are rotated in opposite directions by
a worm upon the main shaft B, which meshes with a worm gear 6 upon the
inclined shaft, and shaft d carries a bevel gear d, which meshes with the bevel
gear which is splined to the work support shaft c. It will thus be seen that a
rotation of the main shaft B, will by means of the worm 3, worm gear 6, and
bevel gears and impart a simultaneous rotation to the feed wheel D and
work support C, in opposite directions, to feed the work along the lip turning
and setting tools, to bring successive portions of the lip of the insoles under the
action of said tools.
If desired the upper surface of the work support C and the under side of the

page_text: feed wheel D may be roughened or serrated to insure a better hold upon the
work and a more positive feeding thereof.
E represents a plough or lip turning tool which as shown in Figs. 1, 2 and 4,
consists of a forwardly projecting curved finger carried by a bracket e, which is
mounted upon some fixed portion of the machine frame as by a set screw el passing
through a slot 2 into the bearing d. The plough E is curved to conform to, and is
adjusted to closely approximate the periphery of the feed wheel 1), so that it will
enter between the lip and feather of the insole, and as said insole is fed along
between the feed wheel D and work support C, the plough E will turn up the
lip to be acted upon by the lip setting tool.
It will be observed that the plough E and the feed wheel 1 act in the angle
between the lip and feather and gage and position the insole as it is fed along,
relatively to the lip setting tool.
.F represents the lip setting tool which as the sole is fed along acts to impart
the proper set to the lip of the sole, or to fix it in the position to which it has been
raised by the plough E. For this purpose the lip setting tool F is arranged to
impart to the fibers of the lip and more particularly to the base of said lip, short
sharp and quick blows delivered in rapid succession, whereby the fibers of the lip
are compacted and the lip made to retain the desired position to which it has been
placed relatively to the surface of the sole.
To secure the above suggested result in the machine of the drawing, the lip
setting tool is arranged to be reciprocated toward and from the edge of the sole
upon the work support, and preferably in an inclined direction so that the tool 1
may act upon the lip at its base.
For this purpose the lip setting tool F is mounted upon the end of a slide f,
which is arranged to reciprocate in an inclined guide way f¹ formed upon the
yoke 3, said guide way being so inclined that the plane of reciprocation of the
slide f and the lip setting tool E', will be substantially parallel to the upper surface
of the feed wheel D. The slide f is held in position in the guide way f¹ by a
plate f, which is secured to said guide way f¹, in any suitable manner as by the
screws f. The reciprocations of the slide / carrying the lip setting tool I may
be imparted thereto by any suitable mechanism, such as a link f, which is
pivotally connected to said slide fat f, and which at its other end is pivotally
connected to one end of a shaft f" in the upper end f of a lever f8, which is ful-
crumed at upon a shaft f10, said shaft fio being mounted in bearings a* in the
ends of upwardly projecting extensions as of the standards a¹. The lower end fu
of the lever f is forked and engages an eccentric upon the main shaft B. The
above arrangement is such, that a rotation of shaft B, will by means of the
eccentric b oscillate the lever f8, upon its fulcrum f10, and by means of the link f
impart a reciprocation to the slide f and the lip setting tool F, carried thereby,
causing said tool to act upon the lip and impart thereto the desired set. The
lip setting tool F, is preferably shaped as shown in the drawing having a working
end which is angularly disposed relatively to the shank, and is removably secured
to the slide f by a screws which passes through a slot s¹ formed in said shank,
whereby said tool I may be adjusted longitudinally upon the slide f. The working
face of the tool F may be shaped as shown, having a substantially straight vertical
face to cause the lip to be set vertically at a substantial right angle to the surface
of the sole, or the working end of said tool may be shaped to lay over and turn
down the lip in a plane substantially parallel with the face of the insole, and in
practice it is the intention to provide a number of lip setting tools having various
shapes of working face suitable to position the lip in any manner desired for
particular work.
While the machine as hereinbefore described constitutes a practicable and opera-
tive lip turning machine which will turn up and set the lip of the sole in the
desired position relatively to the surface of the sole, the thrust of the lip setting
tool against the sole would have a tendency to push the sole off of the work

page_text: support and said sole must be constantly held against the lip turner E and the feed
wheel) with some force by the operator.
In order to hold the insole in position upon the work support C and to withstand
the thrust of the lip setting tool F, against the lip of the insole, the machine
of the drawing is preferably provided with a presser foot H, which is arranged
to grip the insole within the lip, and force the same down against the surface of the
work support C, thus clamping the same at the time the lip setting tool comes into
contact with the lip.
which is
The presser foot H is formed upon the lower end of a rod or stem
mounted loosely in a vertical bearing and prevented from turning therein by any
suitable means such as a pin engaging a slot in said bearing.
The presser foot H is arranged to be moved toward and from the surface of the
work support C to alternately clamp and release the sole thereon, and such move-
ment may conveniently be secured by the following mechanism. The bearing hi
is secured to the forwardly extending arm of a three arm lever, 15, the lower
arm of which is forked or yoke shape, and fulcrumed loosely upon a shaft h
mounted in a bearing carried by the yoke d of the fixed frame; the other arm 8
of the three armed lever being pivotally connected by a stud to a link 10
which in turn is pivotally connected to one end of the rod f6 carried by the
lever f, the other end of the rod fo being connected to the link f which actuates
the slide f and lip setting tool as before described. It will thus be seen that the
presser foot H and the lip setting tool Fare actuated by connected mechanism and
move at substantially the same time towards and from the sole upon the work
support C.
The presser foot H is so positioned that its lower end engages and clamps the work
just before the lip setting tool Facts upon the lip, so that when said tool delivers
its blow upon the lip the sole will be firmly held by the presser foot H.
The presser foot is arranged to yield vertically in its bearing h¹ to accommodate
inequalities in the thickness of the insole and for different thicknesses of insoles
and at its upper end is acted upon by a spring which has a slot 12 which
engages a head h¹³ formed upon a screw h¹ which is tapped into a threaded bearing
in the end of the stem h, and the opposite end of the spring his secured by a
screw 15 to a boss 6 formed on the three arm lever h³.
In order to provide for a horizontal adjustment of the presser foot H toward and
from the lip setting tool F, to provide for different thicknesses of lips, the bear-
ing is provided with a bracket h, having a slot 18 through which passes a
set screw 9, by means of which the bearing is adjustably secured to the arm h
of the lever . By loosening the set screw the bracket 17 may be moved in and
out upon the arm 4, thus moving the bearing and the presser foot H, the slot h¹2
in the spring ¹ permitting a movement of the head of the screw 4 during
such adjustment.
By lifting the spring and turning the screw 4 the tension of the spring
may be adjusted.
In order to accurately adjust the relative times of contact of the presser foot H,
and the lip setting tool F, "with the work, to secure the best results, the stud
which connects the arm 8 with the link is an eccentric stud as shown in dotted
lines Fig. 1, which may be turned to secure the desired adjustment as will be
obvious from an inspection of the drawing.
It is of course to be understood that a constant rotation is imparted to the
feed wheel C and work support D to feed the insole, and in order that the
contact of the presser foot H, with the insole, and the clamping action exerted
thereon during the instant that the presser foot is in contact with the
insole, may not retard the feeding movement thereof, the presser foot H is arranged
to have a slight lateral movement with the sole, which is provided for by mounting
the lever loosely upon the shaft h7, and providing for a slight lateral play of
said lever upon said shaft, and also providing for a lateral movement of the
arm 8 of said lever upon the stud (see Figs. 2 and 4). A spring m secured

page_text: at one end to a stud m¹ upon a fixed portion of the frame, and at its opposite end
to a stud m², projected from one arm or member of the yoked end he of the lever h³
acts to hold said lever and presser foot H in their normal position, and to
return them to such position, from the position to which they may have been
moved by the contact of the presser foot H with the insole.
In practice the end of the presser foot H may engage and clamp the innersole
at a point in line with the line of movement of the lip setting tool F, and thus
form an abutment against which said lip setting tool F may press the lip, or said
presser foot H may be set slightly to one side of the line of movement of the lip
setting tool, and act merely to clamp the insole against the work support during
the action of the lip setting tool thereon, in either case the presser foot is found
to be a desirable feature of the machine, inasmuch as it relieves the operator of the
strain necessary to hold the insole in position against the pounding action of the lip
setting tool.
In the operation of the machine, the insole which has been previously cut or
slit around its edge, is placed in position upon the work support C with the lip
turner E and the edge of the feed wheel D inserted in the slit, the upper flap
formed by said slit being the "lip" of the insole, resting against the lip turner
or plow and the under flap forming the "feather" of such insole resting beneath
the feed wheel and lip turner or plow, the work support rising under the action of
its spring and causing the feather of the insole to be gripped between the upper
surface of the work support and the feed wheel.
A rotation of the main shaft B now causes a rotation of the work support and
feed wheel, and feeds the insole, causing the plow or lip turner to turn up or raise
the "lip" which is acted upon, and given a series of rapid blows by the lip setting
tool, to set or shape the same, as has been fully described.
Instead of forming the lip turner or plow as shown in Figs. 1, 2 and 4, it
may be constructed as shown in Figs. 5 and 6 wherein k shows the bracket
and the lip turner or plow, which upon its under surface has a cut away
portion forming a flange to overlie a portion of the periphery of the feed
wheel D, the upper surface of the plow being rounded and bevelled off at + as
shown in the shaded lines of Fig. 6, whereby said plow will cause the lip of the
insole to be gradually raised and turned up for the action of the lip setting tool
thereon.
In the modified form of the machine shown in Figs. 6 to 10 inclusive the lip
setting tool carries a knife which is arranged to slit the upper edge of the lip
and thereby facilitate the setting of the lip in the position desired by relieving the
strain on the fibers of the lip caused by bending it up in a curved line, and
furthermore produced a much more flexible insole than one in which the lip is not
slit. In the modified form referred to the lip setting tool F is arranged to lay the
lip over upon the surface of the insole and it is therefore somewhat differently
shaped at its working end than the lip setting tool hereinbefore described; it
having in this instance a forwardly projecting tapering toe f* which is arranged
to press the lip of the insole down upon the surface of the sole.
Adjustably secured in a slot t of the lip setting tool F is a knife t' which is
fastened in place in said slot by means of a screw, the said knife being inclined
downwardly as shown and having its cutting edge at a point slightly back of the
tapering toe f* of the lip setting tool F.
The presser foot H of the machine shown in Figs 6 to 10 has no sidewise move-
ment as in the first form of my machine, and its vertical movements are in vertical
alignment with the knife and said presser foot H has upon its rear face a groove
or seat (see dotted lines Fig. 6) into which the cutting edge of the knife is
arranged to be received when making the cut so that said edge will not become
dulled by striking against a hard metallic surface.
Located adjacent to the lip setting tool F is a lip pressing tool
in Fig. 8 has an undercut projection y at its forward end arranged
press the lip after the lip has been turned over and slit by the lip
which as shown
to act upon and
setting tool and

page_text: the knife carried thereby. The lip pressing tool is adjustably secured by means
of the set screw 2 and slot y³ to a fixed portion of the machine. In the machine
as shown the Figs. G to 10 the plow or lip turner E is carried by a bracket e²*
which by means of the bolt ex and slot et is adjustably secured for a vertical adjust-
ment to the bearing of the feed wheel 1).
The other parts of the machine are the same except as above noted as the
machine shown in Figs. 1 to 6 and operate in the same way. By the machine
last d'escribed the lip of the insole will be slit or cut along its upper edge at
each reciprocation of the lip setting tool and after it leaves said tool as the
sole is fed along by the feed wheel the lip will be brought beneath the lip
pressing tool and pressed and set in the desired position.
By slitting the lip and pressing it as described it is caused to more readily
assume the desired position and besides the insole will be more flexible than a
sole with an unslitted lip and therefore preferred in some shoes.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a lip turning machine, the combination with a reciprocating lip setting
tool, of means to so actuate said tool and to support the work so as to cause said
tool to strike and act upon the lip at the base thereof within the angle formed
by the lip and feather of the insole, substantially as described.
2. In a lip turning machine, the combination with a work support, of a reci-
procating lip setting tool movable in a plane inclined to the surface of the work
support, substantially as described.
3. In a lip turning machine, the combination with a reciprocating lip setting
tool, of clamping means arranged to hold the insole against the action of said
tool, substantially as described."
4. In a lip turning machine, the combination with a reciprocating lip setting
tool, of a presser foot arranged to hold the insole during the operation of said
tool, substantially as described.
5. In a lip turning machine, the combination with a reciprocating lip setting
tool, of a work support and means to clamp the insole against said work support
during the operation of said tool, substantially' as described.
6. In a lip turning machine, the combination with a reciprocating lip setting
tool of a clamping device and connected mechanism for actuating said tool and
clamping device, substantially as described.
7. In a lip turning machine, the combination with a reciprocating lip setting
tool, of a clamping presser foot and connected mechanism for actuating said
tool and foot, substantially as described.
8. In a lip turning machine, the combination with a reciprocating lip setting
tool, of a clamping presser foot and means for simultaneously actuating said tool
and presser foot, substantially as described.
3. In a lip turning machine, the combination with lip turning mechanism, of
a rotating work support and means to actuate the same, a clamping presser
foot arranged to clamp the work against said work support, and means to permit a
limited lateral movement of the presser foot, substantially as described.
10. In a lip turning machine, the combination with lip turning mechanism, of
a rotating work support and means to actuate the same, a clamping presser
foot, means to permit a limited lateral movement of said presser foot and a
spring to return said presser foot, substantially as described.
11. In a lip turning machine, the combination with a lip setting tool and
means to reciprocate said tool, of a presser foot, and means to reciprocate said
presser foot, said tool and presser foot movable at an angle toward and from each
other and means to adjust the relative positions of the tool and presser foot, sub-
stantially as described.
12. In a lip turning machine, the combination with a work support, of a feed
5

page_text: wheel inclined relatively to said work support arranged to engage the angle
between the lip and feather of the insole and a lip setting tool movable in a plane
parallel to the feed wheel and arranged to act upon the lip at the base thereof,
substantially as described.
B. In a lip turning machine, the combination with a lip turning device, and a
lip setting device, of a clamping device and actuating mechanism therefor arranged
to alternately clamp and release the work, substantially as described.
14. In a lip turning machine, the combination with a reciprocating lip setting
tool, of clamping means engaging the sole surface within the lip to hold the sole
against the action of said tool, substantially as described.
15. In a lip slitting machine, the combination with a work support, of lip
slitting mechanism, substantially as described.
16. In a lip turning and slitting machine, the combination with a work support,
of lip turning means and lip slitting mechanism, substantially as described.
