Improvements in Eyeletting Machines.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
1
The present invention relates to an eyeleting machine and is embodied in a
machine for setting eyelets, rivets and the like, especially eyelets; the machine
being mainly intended for work on leather stock, especially shoe uppers.
In a machine of this class it is necessary, in order to obtain good results, to
employ a tubular punch cooperating with a flat anvil; since no other kind of a
punch will properly cut holes in leather, or retain its cutting edge when used
with this material for any length of time.
It is the object of the present invention to simplify the construction of the
machine so as to obtain the greatest possible rapidity and efficiency, and to this
end the machine embodying the invention comprises a reciprocating tubular punch
provided with an annular clinching flange from which it projects so as to combine
in one tool a punch and setting device which is adapted first to punch the material
and then to cooperate with another reciprocating setting device adapted to pick
up an eyelet and present the same to the clinching portion of the punch, thus
inserting the eyelet in the previously punched hole and setting or clinching the
same.
In machines as heretofore commonly constructed in which a tubular punch
adapted to operate properly upon leather stock has been employed, it has been
found necessary to utilize a pair of setting devices both operated independently
of the punch itself. In accordance with the present invention, however, this
multiplicity of tools is dispensed with, thereby greatly simplifying the construc-
tion and increasing the rapidity of operation.
The punch employed is smaller in diameter at its cutting edge than the eyelet
which is to be operated upon, so that in the setting operation the tubular cutting
portion of the punch will readily enter the eyelet to prevent the cutting edge from
injuring or being injured by the edge of the eyelet. To insure therefore, that
the eyelet will be properly guided into the hole or opening in the stock, the
machine is provided with means independent of the punch and anvil or co-
operating punching devices, as they may be called, for forcing the punch through
the material after the actual punching or cutting operation is completed, so that
the said punch will project beyond the surface of the .material before the eyelet
is presented thereto.
It is desirable, moreover, that the outer surface of the tubular punching projec-
tion should he tapered somewhat, so that as the said punch is forced through
the material the hole therein will be slightly enlarged, while the tapering projec-
tion will engage the edge of the eyelet as the punch projects into the same. and

page_text: guide the said edge between the exterior of the punch and the material sur-
rounding the same. In this way the eyelet presented by the independent setting
device is properly guided and positioned, and a slight inaccuracy in the original
positioning of the eyelet on the setting device will not result in crushing the
cyelet or damaging the punch, as would be the case if a similar imperfection
existed in a machine which did not have a tapered punch, or a machine in which
the diameter of the punch was as nearly as possible equal to the interior diameter
of the eyelet so that the hole originally punched might be as nearly equal as
possible in diameter to the diameter of the eyelet itself.
The combined tubular punch and setting device may be arranged to have a
reciprocating longitudinal movement toward and from the anvil which constitutes
the other punching member, and also a reciprocating lateral movement to feed
the material to the setting device, which is laterally stationary, after the
punching operation has taken place. These movements are provided for by
novel mechanism forming a part of the present invention, and the said invention
further relates to novel means for varying the extent of lateral movement of the
punch to vary the feed movement of the material and thus change the spacing
of the eyelets, or in other words, the distance between the different eyelets when
a line of them is to be set in a shoe upper or the like.

I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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 an eyeleting machine, the machine being
mainly intended for work on leather stock, especially shoe uppers. In a machine
of this class it is necessary in order to obtain good results to employ a tubular
punch cooperating with a flat anvil, since no other kind of a punch will properly
cut holes in leather or retain its cutting edge when used with this material for
any length of time.
It is the object of the present invention to simplify the construction of the
machine, so as to obtain the greatest possible rapidity and efficiency, and to this
end the machine embodying the invention is provided with a reciprocating
tubular punch having an annular clenching flange from which it projects, so as
to combine in one tool a punch and setting device which is adapted first to punch
the material and then to cooperate with another reciprocating setting device
adapted to pick up an eyelet and present the same to the clenching portion of
the punch, thus inserting the evelet in the previously punched hole and setting
or clenching the same.
In machines as heretofore .commonly constructed in which a tubular punch
adapted to operate properly upon leather stock has been employed, it has been
found necessary to utilize a pair of setting devices both operated independently
of the punch itself. In accordance with the present invention, however, the
multiplicity of tools is dispensed with, thereby greatly simplifying the construc-
tion and increasing the rapidity of operation.
The punch employed is shown as smaller in diameter at its cutting edge than

page_text: he eyelet which is to be operated upon, so that in the setting operation
utting portion of the punch will readily enter the eyelet to prevent the cutting
dge from injuring or being injured by the edge of the eyelet. To insure, there-
ore, that the eyelet will be properly guided into the hole or opening in the
tock, the machine is provided with means independent of the punch and anvil,..
r "cooperating punching devices," as they may be called, for forcing the punch
hrough the material after the actual punching or cutting operation is completed,
so that the said punch will project beyond the surface of the material before the
eyelet is presented thereto. It is desirable, moreover, that the outer surface of
the tubular punching projection should be tapered somewhat, so that as the said
punch is forced through the material, the hole therein will be slightly enlarged,
while the tapering projection will engage the edge of the eyelet as the punch
projects into the same and guide the said edge between the exterior of the punch
In this way the eyelet presented by
and the material surrounding the same.
the independent setting device is properly guided and positioned, and a slight
inaccuracy in the original positioning of the eyelet on the setting device will not
result in crushing the eyelet or damaging the punch, as would be the case if a
similar imperfection existed in a machine which did not have a tapered punch
or a machine in which the diameter of the punch was as nearly as possible equal
to the interior diameter of the eyelet, so that the hole originally punched might
be as nearly equal as possible in diameter to the diameter of the eyelet itself."
The invention further relates to novel details of construction and arrangement,
which will be more fully described hereinafter.

Figure 1 is a front elevation of a machine embodying the invention; Figure 2
a vertical section of the same; Figure 3 a detail in section on the line 3 of
Figure 2; Figure 4 a similar detail in section on the line of Figure 2; Figure 5
a vertical section on planes transverse to that of Figure 2, the upper portion of
said section being taken on a line at the rear of the punch-frame and the lower
portion being taken on a line farther back and just in front of the feed-operating
cam; and Figures 6, 7, 8 and 9 enlarged sectional details of the combined punch
and setting tool and the cooperating setting device, together with a portion of
the feed table, to illustrate the successive steps in the operation, especially with
a view to showing the manner of inserting and clenching the eyelet.
The machine embodying the invention is provided with the tubular punch a,
5 shown as externally tapered and having the annular clenching surface a², the
cooperating setting device b, shown as provided with a spring finger b², and the
eyelet feed chute c, adapted to receive eyelets from the hopper 2 and to be
so as to successively
moved into and out of the path of the setting device b,
present the eyelets to the finger 2 prior to the setting operation. The punch a
10 cooperates in the punching operation with a suitable anvil or support for the
material, the punch and anvil thus constituting cooperating punching
members, the said anvil A being indicated in Figure 6, in which the punch
is shown in the position assumed at the end of the punching operation. It is
necessary, therefore, prior to the setting operation that a movement of one of the
45 said punching members relative to the other should take place in order to permit
the setting device b to move toward the clenching surface a² and cooperate there-
with in the setting operation.
a is arranged to have a lateral movement, the
As herein shown, the punch
same lateral movement which brings the punch into a position to be met by the
50 setting device also serving to feed the material after the same has been punched
To this end the punch is mounted in a laterally movable frame a³, shown a
capable of sliding on the guide rod at, sunported in lugs B, formed in the fron
part of the frame of the machine. The punch is capable of a reciprocating longi
tudinal movement within said frame, as will be hereinafter described, so as t
55 perform the actual punching operation, but is moved with the frame betwee
successive punching operations, so as to feed the material and cooperate in com
pleting the setting or clenching of the eyelet.

page_text: To produce the lateral movement of the frame a³, the said frame is connected,
in accordance with the present invention, with an oscillating member d, (Figure 2)
provided with a radial arm 2, which arm is connected by a universal joint with
the punch frame ³, so as to compensate for the difference between the curved
and rectilinear movements of the two respective parts. As herein shown the
said arm is provided with a channel, the walls of which engage a sliding
block, pivotally connected with the frame, the said block being herein
shown as held in position with relation to said frame by means of a screw a",
having a rounded head a', which constitutes a bearing for the said block. In the
oscillation of the said member d, therefore, the punch frame will be laterally
reciprocated, it being essential that the said punch frame should come to rest at
one end of its reciprocating movement in such a position that the punch will be
in line with the setting device b in order to cooperate. therewith in setting the
eyelet. The member is oscillated in response to the rotation of the main shaft
of the machine, as will be described, and the arm is shown as adjustably
connected to said member, so that the exact position of the punch at the end of
its feed movement may be properly arranged for. As herein shown, the said
arm d² is provided with a hub or collar, Figure 3 having ears or lugs d', each
of which contains an adjusting screw d, which cooperates with a tongue or projec-
tion from the member d. The distance between the lugs is somewhat greater
than the thickness of the tongue do, so that by turning one or the other of the
screws the position of the arm relative to the member d may be determined, as
best shown in Figure 3.
In the construction shown the lateral movement of the punch is utilized to
feed the material so as to produce a completely automatic setting operation, the
punch first descending to cut the material, then moving laterally to transfer
the same to the setting device, and then returning to punch another opening
prior to the next setting operation. It is desirable, however, to provide the
machine with means for varying the extent of the feed movement in case it is
necessary to set part of the eyelets at one distance apart and other eyelets in the
same line at different distances apart. This is accomplished by varying the
lateral or feed movement of the punch, and in accordance with the present inven-
tion the member d, which is shown as a sleeve having a bearing on the shaft (,
which produces the vertical reciprocating movement of the punch, is provided with
an arm, (Figure 5) projecting radially from said member and being connected
with an actuating member which receives a reciprocating movement from a
cam on the main shaft C of the machine, which is adapted to be continually
rotated during the operation of the machine. The said cam cooperates with
engaging surfaces 10, formed in a frame 12, connected with the member 8, the
said member also being provided with fingers or projections d¹³, Figure 4, con-
stituting a fork embracing the shaft C, so as to keep the frame in proper
position with relation to the cam. Thus while the movement of the member ds
is mainly a reciprocating movement said member is free to turn slightly with
relation to the shaft C. so as to properly follow the movement of the arm .
with which it is connected. Thus in the operation of the machine the rotation
of the main shaft C through the action of the cam 9, the connecting member 8,
and the arm will oscillate the member d in accordance with the shape of the
cam do, so as to produce the necessary movement thereof to feed the material and
return the punch to its normal position. It is obvious, however, that the extent
of such movement will be varied by shifting the point of connection between
the arm and the connecting member 8 toward or from the axis of oscillation
of the member d, since the nearer the said point of connection is to the said axis
the longer will be the movement of the said member d. In order that the point
of connection may be thus shifted readily by the attendant even while the machine
is in operation, the arm is shown as connected, by means of a link d, with an
actuating device, shown as an elbow lever №15, pivoted at 16, one arm of said
elbow lever being connected at d with a suitable actuating device, such as a

page_text: readle. (Not herein shown.) Taking the parts, therefore, in the position
ne reed movement.
Figure 5, if the point d" is moved downward it is obvious that the connecting
ember will be carried toward the axis of the member d, thereby lengthening
The amount that the feed movement is lengthened may be
letermined by the stops do, one at each side of one arm of the elbow lever d¨¨,
ne said stops being shown as screw threaded in suitable lugs and held in position
by lock-nuts d, so that they are easily adjustable to vary the extent of movement
or the elbow lever and the consequent variation in the feed movement of the
bunch.
It is of course necessary that the punch should always be arrested at the end
of its feed movement in such position that it will be directly in line with the
lower setting device, so as to receive the eyelet therefrom and cooperate there-
with in the setting operation. To this end the member do is connected with
the arm by means or a stud as, arranged to engage the walls of a slot
in the member d, and the said walls of the said slot do are curved upon the-
are of a circle struck from the axis of the shaft C when the said arm is in such
a position that the punch is directly in line with the lower set. It is obvious,
therefore, that no matter to what position the stud 80 is shifted there will be
no variation in the position of the punch at this point of its travel, so that no
matter what the feed movement may be the said punch will always be arrested
in the proper position with relation to the setting device. In other words, the
extent of teed movement is varied by initially varying the extent of backward
movement of the punch, so that said punen may be caused to engage the
material at varying points on the punch-block, while it always moves said
material to such a position that the punched hole is in line with the lower set,
which is laterally stationary. The extent of feed movement, therefore, is equal
to the distance between the point where the material is punched and the point
where the eyelet is set, and the said distance is variable in accordance with the
variation in the initial rearward movement of the punch.
The vertical reciprocating movement of the punch is produced, as has been
stated, through the agency of the shafte which is provided with a gear e² co-
operating with a segmental gear c³ connected with an arm et pivoted at e² on a
portion of the frame of the machine and provided with arms e constituting a
forked extremity to engage opposite sides of the cam e upon the main shaft C.
As the said shaft rotates, therefore, the arm e will be swung upon its pivot,
thus producing an oscillating movement of the shafte which is provided with
an eccentric pin es projecting from its. end, which pin cooperates with engaging
surfaces e fixed with relation to the punch and shown as formed in a block or
The said surfaces constitute
frame e which is connected with the punch .
O the walls of an elongated channel, so that the block eo is free to travel laterally
with relation to the eccentric es and to cooperate therewith regardless of the
lateral position of the said block and punch.
As herein shown, the eccentric pin e8 does not engage directly with the
surfaces e, but is fitted into an intermediate block 12 which fits in the said
5 channel and practically constitutes an intermediate eccentric strap. As the shaft
oscillates, therefore, the punch is carried downward toward the anvil to punch
the material, and in order to free the punch from the anvil prior to the lateral
movement, the parts are so arranged that the eccentric pin travels enough in
the oscillation of the shaft to carry the punch down into contact with the anvil
50 and then slightly up away from the same, the cam e being so shaped that there
is a dwell in the movement of the shaft e at the end of this time, while the
lateral movement of the punch frame immediately begins This is illustrated in
Figures 6 and 7, Figure 6 showing the position of the punch at the completion
of the punching operation, and Figure 7 the position of the punch after the feed
55 movement has begun.
The slight upward movement of the punch prior to the lateral feed movement
separates the same from the anvil or cooperating punching member, so that the

page_text: lateral movement may be freely accomplished, it being obvious, however, that
the parts may be so timed that these movements may begin almost simultaneously,
thereby insuring great rapidity of operation.
It will be seen, however, irom Figure 6 that at the end of the punching
operation the cutting edge of the punch is on a level with the lower surface
of the material and that it does not project beyond the surface of the material
at all.
It is desirable, however, that the punch should be somewhat smaller
than the edge of the eyelet which is to be set in order to obviate all liability
that the edge of the punch and the edge of the eyelet may come in contact with
each other, and thereby injure or destroy one or both, and in any event prevent
the proper setting of the eyelet in that particular hole. With the punch
smaller than the eyelet, however, and flush with the surface of the material
the eyelet instead of entering the opening in the material would come in contact
with the uncut material around the punch if the material were allowed to remain
in the position shown in Figure 6 during the setting operation. To insure the
proper setting, therefore, and to assist in guiding the eyelet into the opening,
the machine is provided with means for forcing the punch completely through
the material until it projects beyond the surface of the same after the punching
operation is completed and prior to the setting operation. As herein shown,
this is accomplished by providing the anvil A or any suitable portion of the
feed table with projecting fingers A3 (shown on a large scale in Figures 6, 7, 8
and 9). These fingers project upward beyond the end of the punch, one at each
side thereof, as the said punch travels laterally from the position shown in
Figure 6 to the position shown in Figures 8 and 9. The material carried along
by the punch, therefore, will come in contact with the upper surfaces of the
fingers A and will be forced upward onto the punch, as shown in Figure 7, so
that when the said punch is in the position to cooperate with the setting device
it will project wholly through the material and beyond the lower surface of
the same. This is best shown in Figure 8 in which it will be seen that the
punch projects into the eyelet E until the edge of the eyelet engages the tapered
walls of the punch and is thereby guided into the hole made in the material,
which is enlarged sufficiently to properly receive the eyelet, so that the said
eyelet cannot fail to enter and be upset or clenched, as shown in Figure 9.
It is obvious that the means for forcing the punch through the material after
the punching operation may be readily modified, and it is not intended, there-
fore, to limit the invention to the particular means herein shown and described.
The lower set is carried by a vertically reciprocating rod 63, adapted to be
reciprocated by means of a wrist pin C2 upon a disc C3, formed upon the main
shaft C. The said wrist pin C2 enters an opening in a block 6, capable of
sliding in a cross head ; suitably connected with the rod 3, so as to reduce a
regular reciprocating movement of the setting device. The said setting
device is vertically adjustable with relation to the rod 63 by means of a screw
threaded adjusting member 6, which bears against the end of a shell 6, which
in turn engages the end portion of the set b, the upper portion of said set being
engaged by an annular cap or nut 8. In adjusting the set the nut 68 is turned
to such a position as to determine the proper position of the set, and the adjusting
member is then screwed up until the parts are locked, as will be easily under-
stood by reference to Figure 2.
The finger 62 is acted upon by a spring 69, contained in the shell 67. The said
finger, which is adapted to pick up an eyelet from the chute c in the usual way,
is tapered, so as not to come in contact with the edge of the punch, and will
usually be depressed by contact with the piece of leather last punched out of
the material.
To retain the material in position after the setting operation has taken place
and prior to the return movement of the punch, the machine is provided with a
gripper member f, spring-pressed against the feed table or anvil, as shown, and
connected with a vertically movable rod f2, acted upon by an arm f³, pivoted at f*

page_text: and operated by a cam f5 on the shaft C. The parts are so timed that the
gripper descends and engages the material just after the feed movement is com-
pleted and remains in engagement therewith as the punch and setting device
move apart. To enable the operator to insert the material prior to starting
the machine, the gripper member is also arranged to be acted upon by a lever f³,
connected with a suitable treadle or actuating device. (Not shown).
The feed chute c may be reciprocated or oscillated in any suitable or usual
way to present the eyelets to the setting device and is herein shown as oscillated
by means of a came, acting on the forked extremity of an elbow lever c³,
suitably connected with an oscillating frame which carries the said eyelet-chute
and feed hopper, the construction and arrangement of which need not be further
described, since they form no part of the present invention.
It is to understood that while the punch has been herein before described
as laterally movable, constituting also the feed member of the machine, such a
construction is not essential to the invention, since other means for feeding
the material may be employed while it is obvious that other means might also
be employed for laterally separating the punch and anvil to permit the setting
device to come in line with the said punch.
It is further obvious that many other modifications might be made in the
specific construction and arrangement of the machine, and it is not intended,
therefore, to limit the invention to the particular embodiment thereof which
has been herein shown and described.
