Improvements in or relating to Punching and Eyeletting Machines.
We, MARSHALL HENRY PEARSON, Engineer, and PEARSON AND BENNION,
LIMITED, Engineers, of Union Works, Belgrave Road, Leicester, do hereby
declare the nature of this invention to be as follows:-
This invention consists of improvements in or relating to punching and
eyeletting machines and the object thereof is to construct machines in such
a way as to enable both sides of the upper of a boot or shoe to be punched and
eyeletted at one operation, .e. an upper may be operated upon in an upright
folded position, or in a modified form of the machine in a flat position with
the two edges parallel to each other, and both rows of eyelets inserted simul-
taneously.
To carry out the invention and enable the upper to be operated upon in an
upright folded position, the frame of the machine may be provided with a
stationary metal plate or tongue upon which the upper may be placed in an
upright position with the toe part away from the operator.
Pivotted on studs fixed in the frame are two upper clamps consisting of
levers approximately bell-crank shape, their lower or vertical arnis depending
upon each side of the said plate or tongue and their upper horizontal arms inter-
locking, by which means the said upper clamps work in unison.
One of the said levers or clamps has an arm or other extension provided with
a runner operated by a cam on the driving shaft, the said cam causing the upper
clamps to release the work when the latter is fed forward as hereinafter men-
tioned.
The said clamps may be held together in their closed position on the work
by a spring or other suitable means.
A lifting frame consisting of a sleeve with arms, is mounted on a shaft carried
on the framing at a right angle to the studs upon which the upper clamps
are pivotted.
The said lifting frame is provided to raise the eyeletting dies into the position
previously occupied by the punches and is operated by an arm having a runner
thereon being engaged by a cam on the driving shaft.
The punches and eyeletting dies are carried at the bottom ends of a feed
frame connected to the arms of the lifting frame.
The said feed frame preferably consists of a sleeve or hoss provided with arms
depending therefrom and having bosses in which the punches and eyeletting
dies are located.
It will be understood that the punches are located in the feed frame above
the eyeletting dies, and that after the upper has been punched the feed frame
is raised by the lifting frame thereby bringing the eyeletting dies into position
as before mentioned.
The punches and eyeletting dies are operated upon by two eyeletting levers
preferably pivotted on the same studs as the two upper clamps and are operated

page_text: in a similar manner i.e. their upper horizontal arms interlock and one lever is
operated by a cam on the driving shatt, and they close and open simultaneously
the cam being arranged nrst to operate the punch bars and then the eyelet
bars, the said eyeletting levers consequently make two strokes to one revolution
of the machine.
The punch bars may be circular in shape having the punches fixed in their
ends and may be provided with springs to cause them to recoil after the eye-
letting levers have returned to their outer position.
The eyelet bars may be formed of tubes, having stopped ends and coiled springs
inside to eject the punches.
Attached to the feed frame and movable therewith is a centre plate provided
for carrying the eyelet dies.
The latter are formed as heretofore excepting the nipples are preferably
very much shorter or shallower and rounded on the top, the said centre plate
being slightly recessed as usual round the nipple, and the remainder of the
plate being flat for the punches to operate against; the upper being fed by the
eyeletting dies in their closed position.
The eyelets may be fed from an eyelet box down a raceway or shoot in the
usual manner, except however, that the said raceway or shoot is preferably
divided into two branches similar in shape and delivers the eyelets opposite
the bars in the punching and eyeletting position, viz. after the eyelet bars have
been raised.
The eyelet box and both raceways or shoots are adapted to oscillate being
pivotted to the frame of the machine and actuated by a cam on the, driving shaft.
The feed (ie. the distance between the punch holes) may be adjusted by
pivotting to the frame a cam lever oscillated by a runner on one arm, the other
arm of said lever engaging a cam lever link, the further end of the latter being
connected to a feed frame link, whose opposite end may be pivotted to the
feed frame. i
Jointed also on the connection between the cam link and the feed frame
link, is an adjusting link whose lower end is connected to an adjusting lever
pivotted to the frame.
The axis of the connection between the cam link and feed frame link and
the pivot of the adjusting lever, is in line when the feed frame is in position for
punching.
The said adjusting lever may be controlled by a quadrant and pins and is
essential because of the difference of the feed between eyelets and hooks, and
it may be operated by a treadle.
The lower ends of the eyelet raceways or shoots may be provided with an
adjustable stop so that when the feed is lengthened and hooks are being inserted,
the adjusting lever may engage the said stop and move the raceway or shoot
out of position.
To punch and eyelet the work in a flat position with the two edges parallel
the horn instead of being placed at a right angle to the frame as shown in
Specification of Letters Patent No. 8477 of 1891 is placed parallel thereto and
the upper is placed thereon with the toe away from the operator.
It is obvious that as both sides of the upper are to be eyeletted at one opera-
tion, that there are two punches and two eyelet dies and the raceway or shoot
from the eyelet box is divided so as to have two deliveries, one for each eyelet
die.

page_text: improvements in or relating to running and Dyelecting machines.
We, MARSHALL HENRY PEARSON, Engineer, and PEARSON AND BENNION,
LIMITED, Engineers, of Union Works, Belgrave Road, Leicester, 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 follow-
ing statement:-
The present invention consists of improvements in or relating to punching
and eyeletting machines and relates particularly to machines designed to punch
and set the eyelets simultaneously in two layers of material, such as the sides
of a boot or shoe upper.
The main object of the invention is to increase the production of eyeletting
machines, i.e. enable a greater amount of work to be accomplished in a given
time than heretofore, and also to render the punches and setting dies more certain
and uniform so that both edges of the upper or vamp of a boot or shoe may be
so punched and eyeletted that the holes and eyelets register with the greatest
accuracy and the loss heretofore occasioned by imperfectly and improperly
eyeletted boots and shoes entirely obviated.
A further object is to improve the work holding devices to positively insure
the immovability of the work during the operation of the punching and eye-
letting dies in forming the holes and setting the eyelets and thus insure the
correct and uniform action of such devices on the work.
A further object is to improve and simplify the work feeding mechanism and to
provide simple means under the control of the operator for varying the feed of
the work and also to simplify the eyelet feeding mechanism and to provide means
whereby such mechanism may be thrown out of operation when the machine is
employed in punching for hooks instead of eyelets.
To these ends the invention consists of a machine possessing certain features
of construction and arrangement of parts, one form of said machine being here-
inafter described, reference being had to the accompanying drawings and the
characters marked thereon forming a part of this specification, the same characters
designating the same parts throughout the several drawings.
Figure I shows a front elevation of a machine embodying my invention with the
lower part of the supporting standard omitted, and Figure shows a side elevation
of the machine, as it appears in Figure 1 looking at the right.
Figure 3 shows a vertical section on the line - Fig. 2 with the eyelet
box and shoots omitted and also on the line y-y Fig. 2 through the clutch
and driving shaft, and Fig. 3ª is a detail view hereinafter referred to.
Figure 4 shows a vertical sectional view illustrating the construction of the
punch frame and the mode of operation of the punches and dies.
Figure 5 shows in an enlarged view the punch frame removed, also showing
the lower part of the guide plate, with the edge guide, the punch and setting
die in one side being shown in the vertical section to illustrate the interior
construction.
Figure 6 shows in front elevation and partial vertical section details of the
mechanism, also enlarged.
Figure shows the cam shaft and the cams and pulleys thereon.
Figures 8, 9 and 10 show details of the start and stop mechanism.
Figures 11 and 12 show respectively an elevation and a vertical sectional view
of the hopper, eyelet box and attached shoots.
Referring to the drawings which show one embodiment of the invention

page_text: selected for the purpose of illustration represents the frame or head of the
machine mounted upon a standard 2 (the upper part only of which is shown in
the drawings).
In the frame 1 are provided suitable bearings 3 in which is mounted the
cam shaft which carries a series of cams abcde and a pulley which actuates
the several instrumentalities of the machine as will hereinafter be described.
Motion is imparted to the cam shaft 4 by the pulley 5 which is constantly
driven by a belt from any suitable source of power and which is coupled and
uncoupled from the shaft 4 by the start and stop mechanism, which will now
be described.
Upon the shaft 4 is mounted a friction disc 6 which is secured to said shaft
so as to turn therewith and also to have a limited movement along said shaft
by means of a key 7, secured in the hub of the disc 6 and projected into an
elongated key-way 8 formed in said shaft 4. The disc 6 has a bevelled face 9
which when brought into contact with a leather or frictional surface 10 carried
by the pulley 5 will lock the disc 6 to said pulley 5 and cause the disc 6 and
shaft 4 to partake of the rotary motion of the pulley 5 thus imparting motion
to the movable part of the machine.
The disc 6 is moved along the shaft 4, to cause its bevelled face 9 to engage
the friction surface 10. on the pulley 5, by means of springs 11 which are
seated in a nut 12 threaded on the extended hub 13 of the disc 6, which springs
bear against a plate or washer 14 carried by a threaded bolt 15 screwed in the
end of the shaft 4. The disc 6 on the opposite side of its periphery carries a
bevelled face 16 which is arranged to be brought into contact with a friction
surface 17 carried by a fixed annular brake plate 18 which is provided with
extended arms 19 which are adjustably secured by means of threaded bolts 20
and threaded sleeves 21 to the integral arms 22 of the frame 1. It will be
noted that the pulley 5 is recessed as shown at 23 and that the disc 6 and annular
brake plate 18 are received in said recess and that the brake plate may be
adjusted with relation to the disc 6.
The foregoing arrangement is such that a movement of the disc 6, by means
of the springs 11, towards the pulley 5 will cause the pulley to turn said disc
and the shaft 4 to set the machine in motion, and a movement of the disc 6 away
from the pulley 5 and into contact with the fixed brake plate will disconnect
the pulley from the shaft and stop the machine, the pulley however, continuing
to rotate.
It is designed that the movements of the disc 6 shall be produced by
mechanism under the control of the operator, whereby he may cause the machine
to make one or a series of cycles of operation as desired.
Mounted to slide vertically upon a loose collar 24 upon the hub 13 of the disc 6
and confined between a flange 25 of said collar and the brake plate 18. is a
frame 27 which carries inclines 28 which co-operate with inclines 29 formed
on the said brake plate 18, the arrangement being such that an upward move-
ment of the frame 27 will permit the springs 11 to move the disc 6 in engage-
ment with the pulley 5 and a downward movement of such frame will by
means of the co-operating inclines 28 and 29 and the collar 24 and nut 12 move
the disc 6 in the opposite direction to disconnect it from, the pulley 5 and connect
it with the brake plate 18, stopping the machine. The frame 27 is moved
upwardly by means of a spring 30 which is seated in a recess 31 in the collar 24
and it is automatically moved downward by means of an eccentric strap 32 which
encircles an eccentric 26 formed in the hub of the disc 6, said eccentric strap 32
reciprocating vertically during the rotation of the disc 6, and being guided by
a pin 33, fixed to the depending arm 34 of the frame 27, which engages a slot 35
formed in a depending arm 36 of the eccentric strap 32. Pivotally connected to
the depending arm 34 of the frame 27 is a detent 37 which is provided with a
notched dog 38 which when the detent is rocked to the position shown in
Figure 9 is arranged to be engaged by a shoulder 39 on the arm 36 of the

page_text: eccentric strap 32, whereupon the downward movement of the eccentric strap will
cause the frame 27 to move downward to release the clutch and apply the brake
as before described.
If the detent be rocked to the position shown in Figure 8, the dog 38 will
be disengaged from the shoulder 39 and permit the frame 27 to be raised. by
the spring 30 to release the brake and connect the clutch. The detent 37 is
pivotally connected by a rod (not shown) to a foot treadle (not shown) whereby
it may be rocked as desired by the operator, it being clear that if it be held
in the position shown in Figure 8, the machine will continue to run, but as soon
as the detent is rocked to the position shown in Figure 9, the next downward
movement of the eccentric strap 32 will cause a downward movement of the
frame 27 and the consequent stopping of the machine.
In the present machine, as heretofore stated, it is designed that the eyelets
be set in both edges of the upper of a shoe simultaneously, the sides of the
upper being laid together with the edges in alignment with or coincident with
each other, and placed in the machine with their inner surfaces disposed against
the opposite sides of a tongue or guide plate hereinafter called the guide plate
and a die plate and the edges of the upper in contact with a suitable edge guide
which regulates the distance at which the eyelets are placed form the edges
of the upper.
While thus positioned the machine is set in operation and the upper is gripped
or clamped against the guide plate by suitable clamping devices, the punches
are operated to punch the holes and the eyeletting dies receive and insert the
eyelets in the holes just punched, then the clamping devices release the upper
which is fed forward by the eyeletting dies, all of which is accomplished in the
machine of the drawings as follows:-
The guide plate 40 is secured to the frame at the right hand thereof, by
means of screws 41 which pass through the shank of said plate and said plate 40
as clearly shown in Figures 1 and 6, extends angularly forward towards the
right of the machine, whereby the upper may be accurately placed therein, said
plate extending between the two flaps or sides of the upper and the toe of the
upper extending towards the left of the operator as he faces the machine.
See the dot and dash lines in Figure 6.
Pivotally secured to the shank of the guide plate 40 is an edge guide 42 which
has guide faces 43 disposed upon opposite sides of the shank of the guide
plate against which the edges of the upper bear, and also provided with guiding
Hanges or wings 44 which confine and guide the edges of the upper, preventing
the lateral displacement thereof during the feeding movement.
The edge guide is provided with an extension beyond its pivotal point in
which is confined a stop pin 45 the lower end of which enters and is fast in
the upper edge of the guide plate 40, the position of the edge guide on said
pin 45 determining the position of the eyelets with relation to the edges of
the upper.
The clamping devices in the machine of the drawings are shown at 46 and
are carried by or formed integrally with the arms 47 of the bell crank levers 48,
which are fulcrumed upon shafts 49 mounted in bearings 50 of the head or
frame 1. The arms 47 extend downward and towards each other as clearly
shown in Figure 2, so as to bring the clamping devices 46 upon opposite sides
of the guide plate 40 against which the sides of the upper are clamped while
being punched and the eyelets set. If desired the clamping devices 46 may
have their inner faces provided with rubber or other soft surfaces 51 to prevent
injury to the upper of the shoe.
Each lever 48 has an arm 52, the meeting ends of which are provided with
the interconnecting head 53 and fork 54, whereby a rocking motion imparted to
one of said levers will be imparted to the other to cause the clamping devices 46
to move towards and away from the guide plate 40. This rocking movement in
one direction, preferably in the direction to bring the clamps 46 in contact

page_text: with the work, is produced by a coiled spring 55, the opposite ends of which
are secured respectively to the arms 47, and the rocking movement in the
opposite direction, to release the work, is produced by the cam a, the periphery
of which is engaged by a cam roll 56 carried by an arm 57, projected from one
of the levers 48, as shown clearly in Figure 2 of the drawings.
The cam a is preferably so formed as to permit the spring 55 to maintain the
clamps 46 in contact with the work at all times except during the feeding of
the work.
The punches and eyelet setting dies in the machine of the drawings are
arranged as follows:
The punches 58 are threaded into tubular sleeves 59 which are mounted to
slide in tubular bearings 60 so as to advance and retract the punches toward
and from the 'work, said sleeves being retained normally retracted or in the
position shown in Figure 5, by means of springs 61 confined in the sleeves 59
and entering and hearing at one end against the closed end of adjusting bolts 59ª
and at the opposite end against pins 62 fixed in the bearings 60 and passing
through slots 63 formed in the sleeves 59. Each punch 58 is provided with an
opening 64 arranged to receive therein and eject through the obliquely drilled
hole 64 the piece of leather punched from the upper. The bearings 60 are
supported by the yoke-shaped frame 65, which will be hereinafter called the
feed frame, which is supported upon a shaft 66 mounted in bearings 67 carried
by the arms 68 of a lifting frame 69, which is fulcrumed on a shaft 70, mounted
in bearings in the frame 1, and is provided with an arm 71 carrying a cam
roll 72 which engages the cam groove in the cam b, whereby the lifting frame 69
is operated to raise and lower the feed frame for a purpose to be described. The
feed frame 65 also supports in bearings 73 below the bearings 60 the sliding
tubular sleeves 74 into the inner end of which are threaded the setting dies 75
which may be of any usual or preferred form and provided with the sliding
pins 76 for picking off and sustaining the eyelets.
The tubular sleeves are maintained in the position shown in the drawings with
the setting dies retracted and the pins 76 projecting therefrom by means of
coiled springs 77 which bear at one end against a pin 78, fastened in the bearings
73 and passing through slots 78 formed in the sleeves 74 and also in a stop
sleeve 79 fitted in the sleeves 74. The outer ends of the sleeves 74 are open as
at 80 and in the openings are fitted hardened blocks 81 which are backed up by
strong springs 82, the inner ends of which bear against the end of the stop
sleeve 79. The above arrangement is such that the two springs contained in
the sleeves 74 act independently of each other, the springs 77 acting to return
the sleeves to their retracted position and the strong springs 82 permitting a
cushioning or yielding actuation of the dies during the upsetting and clinching
of the eyelets.
Cooperating with the punches 58 and the setting dies 75 is an anvil, punch
plate or die plate hereinafter called the die plate 83 which is fastened to the
feed frame 65 by means of the headed bolt 84, and which has its lower end
disposed between the two sets of punches and setting dies and substantially in
alignment with the guiding plate 40, it being understood that the lower end of
plate 83 enters between the two sides or flaps of the shoe.
In punching the holes for the eyelets the punches act against a hardened
plug 83 and pin 83b inserted in the die plate 83, the said pin 83b operating to
remove and eject through the hole 64ª the pieces of leather punched from the
upper as before stated; and immediately below the point where the punches
operate, said plate 83 is provided on opposite sides with nipples or dies 85 which
cooperate with the setting dies 75 in upsetting and clinching the eyelets.
The punches and setting dies are advanced towards the die plate 83 by means
of bell crank levers, hereinafter called punch and die levers 86, which are ful-
The
crumed upon the same shafts 49 which support the work clamp levers 48,

page_text: arms 87 of the punch and die levers S6 are arranged to engage the bolts 59³
in the ends of the sleeves 59 of the punches and aiso to engage the blocks 81
in the ends of the sleeves 74 of the setting dies as will be described, and the
arms SS of said levers are pivotally connected as by the pin and slot connec-
tion 89 Eo that motion imparted to one will be transmitied to the other and
cause a simultaneous operation thereof. One of said punch and die levers is
provided with a cam ron 30 which engages the peripheral cam c, whereby said
levers are rocked to operate the punches and eyeletting dies.
It will be noted that when the feed frame is in the position shown in Figures 2
and 4, the bolts 59 of the punch sleeves 59 are in position to be engaged and
advanced towards the plate 83 by the punch levers, after the punches have been
actuated the feed frame is raised to place the sleeves of the eyeletting dies in
position to be engaged by the punch levers which will again be actuated to
advance the setting dies towards the die plate 83 to cause said dies to clinch
and set the eyelets.
In this connection it should be stated that the cam c is so formed as to impart
two oscilations to the punch levers during a single cycle of motion of the machine,
first to advance the punches and then to advance the setting dies and that the
cam is so shaped and turned with relation to the cam e as to raise and lower
the feed frame alternately with the oscillations of the punch levers.
The work is fed along by the setting dies, and for this purpose while said
dies are still in engagement with the eyelets which have been clinched or set,
the feed frame is moved laterally with relation to the guide plate 40 or in the
direction shown by the arrow in Figure 6. This movement of the feed frame 65
is accomplished by means of a link 91, one end of which is pivotally connected
to an arm 95 extending from a sleeve 96 said sleeve being mounted in bearings
98 in armis 99 projecting from the fixed frame 1. The sleeve 96 also has another
arm 100 which engages a cam path formed in the feed cam d.
The above arrangement is such that the rocking movement imparted to the
sleeve 96 by means of the cam d, will, by means of the links 94 and 91 be
transmitted to the feed frame 65 thus feeding the work along as hereinbefore
described.
In order to adjust the feeding movement of the swinging feed frame 65 to
produce an adjustment in the spacing of the eyelets the following feed adjusting
mechanism is provided:-
To the links 91 and 94 at the pivotal point 93 there is pivoted a link 102 which
at its lower end is pivoted at 103 to a feed adjusting, lever 104 carried by
a rockshaft 105 mounted in a bearing 106 of the fixed frame 1, and at its
opposite end provided with an arm 107, to which is connected by a rod (not
shown), a foot treadle (not shown) whereby the feed adjusting lever may be
rocked by the means described to vary the angle of motion of the pivotal con-
nection 93 of the links 91 and 94, and thus, regulate the throw of the feed
frame 65.
The swinging movement of the feed adjusting lever 104 is limited by stops 108
which are arranged to be fitted into the openings in the quadrant plate 109 which
is mounted to have a slight swinging movement, for a purpose which will herein-
after appear, upon the end of the shaft 105 in rear of the feed adjusting lever 104.
The eyelets are supplied to a hopper 125 the lower part or elbow of which
passes into a socket 126 and is retained therein by a collar 127 fixed in any
convenient way on said elbow or part.
The socket 126 is threaded over the sleeve 128 of the eyelet box 110.
To insure the vertical position of the hopper 125 during the movement of the
eyelet box 110, a rod 129 fixed by screws 130 to the frame 1 passes upward and
engages in a slot 132 the stud 131.
The eyelets are delivered from the hopper 125 to the eyelet box 110 from
which lead two eyelet shoots 111 which are downwardly and laterally extended

page_text: and given a quarter turn so as to properly present the eyelets to the setting
dies, the lower ends of the shoots being notched as shown at 112 whereby when
they are advanced into the line of movement of the setting dies, the pins 76
will enter and remove an eyelet from each shoot. The shoots 111 are preferably
formed integrally with the bottom of the eyelet box 110, as shown, and said
eyelet box is fulcrumed upon shafts 113 fitted in hearings 114 of the frame 1,
whereby the eyelet box and shoots may be rocked to advance the shoots from the
position shown in Figure 1 to a position which will place their lower ends in
fine with the setting dies.
Said eyelet box is rocked in one direction so as to advance the shoots to the
point of operation of the setting dies by means of a spring 115, one end of
which is connected to an arm or lever 116 fixed to one of the shafts 113 and
the opposite end of which is secured to the frame 1, said lever being provided
with a cam roll which engages the cam e, on the shaft 4, by means of which the
eyelet box is rocked to retract the shoots. A rotating brush 118 is located within
the eyelet box, and is mounted on a shaft 119 which passes through a bearing 120,
and carries at its outer end a pulley 121 driven by a belt 122 which passes over
idle pulleys 123 and is driven by a pulley 124 on the driving shaft 4. When
the machine is used on work requiring the insertion of hooks as well as eyelets
after the requisite number of eyelets have been inserted the shoots 111 are
prevented from moving as described and are held in their retracted position
against the tension of the spring 115. This is accomplished by a spring pressed
pawl 118 carried by an arm 109ª projected from the quadrant plate 109, and
arranged to engage the lower end of the lever 116, said quadrant plate being
rocked backward when desired, by means of the feed adjusting plate 104 and
the foot treadle as described, said feed adjusting plate engaging the stop 108
at the left as shown in Figure 3a and moving back the quadrant plate to place
the pawl in position to engage the end of the lever 116. The quadrant plate is
normally held from swinging to the left during the setting of eyelets by means
of the stud 120 fitted to turn in a bearing in the standard 2 and passing through
a circular opening 121 formed in the arm 109 of the. quadrant 109, the arrange-
ment being such that when the stud is in the position shown in Fig. 3 the
quadrant plate may have a slight movement to the left to the position shown in
Figure 3 so that the hook 118 engages the lever 116 and prevents the eyelet
box from swinging but when said stud is given a half turn the said plate will
be held from movement to the left..
The operation of the machine of the drawings is as follows:-
The work is positioned in the machine as shown in dotted lines Fig: 6 with
both edges of the upper parallel to each other and bearing against the edge guide
upon opposite sides of the guide plate 40 and the die plate 83 with the work
clamps 51 under the force exerted by the spring 55 clamping both edges of the
upper as described. The detent 37 is now turned by the foot treadle to permit
the clutch to operate imparting motion to the cam shaft. The rotation of the
cam shaft causes the punch levers to advance the punches towards the die plate
to punch holes in both edges of the upper.
The punch levers are then retracted and the feed frame lifted by the lifting
frame to bring the setting dies into the position formerly occupied by the punches
and in line with the holes formed by the punches and so that the ends of the
setting die carriers may be engaged by the punch levers. The punch levers
are then again operated to advance the setting dies towards the complementary
dies on the die plate, during which movement the eyelet box and shoots are
rocked and retracted, permitting the pins of the setting dies to remove an eyelet
from each shoot, which eyelets are carried towards the work and set or clinched
in the holes formed by the punches.
While the work is still held between the setting dies and the die plate, the
clamping devices are actuated to release the work, and the feed frame is rocked

page_text: laterally to move the work forward, after which the clamping devices again
clamp the work and the feed frame is returned and lowered for another operation
of the machine.
In this connection it is to be noted that the punch levers are provided with
laterally projected off-set ends 87* which hold the setting dies against the work
to hold and support the work during the feed movement of the feed frame while
the clamping levers are released.
While I have shown in the drawings and described in this specification the
preferred form of my invention, my invention is by no means specifically limited
thereto but is susceptible of embodiment in various forms without departing
therefrom. Furthermore it is to be understood that certain features of my
invention are not limited to a duplex eyeletting machine but may be used in
other forms of machines.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. An eyeletting machine comprising suitable mechanism, and means for
causing said mechanism to simultaneously set two eyelets in axial alignment
in two parts of work juxtaposed.
2. In an eyeletting machine, the combination with a feed frame, of a pair
of punches and setting dies disposed upon opposite sides of the feed frame,
substantially as described
3. In an eyeletting machine, the combination with a guide plate of an edge
guide having a guiding face upon each side of said plate, substantially as
described.
4. In an eyeletting machine the combination with a guide plate of work clamp-
ing devices and means to actuate said devices to clamp the flaps of a boot or shoe
upon opposite sides of said guide plate, substantially as described.
5. In an eyeletting machine the combination with a feed frame, of a pair of
punches disposed upon opposite sides of said frame and connected mechanism
for simultaneously actuating said punches, substantially as described.
