Improvements in Corset Eyes and in Blanking and Studding
Machines adapted for Producing same.
I, PHILIP MIDDLETON JUSTICE, of 55 & 56 Chancery Lane, London, Fellow of the
Chartered Institute of Patent Agents, do hereby declare the nature of this
invention (which has been communicated to me from abroad by The Warner
Brothers Company, a corporation under the laws of the State of Connecticut,
U.S.A., having its principal office at No. 359 Broadway, in the City of New York,
State of New York, U.S.A.) and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:
This invention relates to certain new and useful improvements in corset eyes
and in blanking and studding machines for producing same, and it has for its
object to simplify and increase the efficiency of such machines and to render
them wholly automatic in operation. With this object in view, the invention
consists in means for feeding a metal strip or sheet to punching or perforating
devices whereby holes are formed in the strip, of devices for cutting out sections
of said strip, and mechanism for inserting sections of wire in the holes of the
sections of the strip and for upsetting the wire upon both sides of the severed
sections to form studs.
The invention is shown as embodied in two different machines for accomplishing
the same general results by somewhat different means, as well as a different order
of the same steps.

strip showing the operation of the tools thereon.
Before describing the details of the improved machine, the operations which it is
desired to effect will be set forth by reference to Fig. 1.
A strip X, of composition or suitable metal, is fed in the direction of the
arrow 1, between punches which operate to form an elongated recess r, holes a¹, ¹,
and to cut out the blank Y. This blank is then transferred in the direction of the
arrow 2", to a suitable carrier which moves laterally as indicated by the arrow 3ª.
During the formation of the blank Y, devices are actuating to feed wires a, a,
in the direction of arrow 5*, and from the ends of these wires, sections are cut.
These sections are moved laterally as in the direction indicated by the arrows G³,
to bring their ends in alignment with the holes x, x¹, of the blank which has
been brought to a plane above the sections. The blank is now moved towards
the wire sections as indicated by arrow 4, and the ends of said sections are
received in the holes ¹, ¹, thereof. After this suitable heading devices are
actuated to upset the sections upon opposite faces of the blank to form studs.
By this means there is formed what is known to the trade as a corset hook
eye, illustrated in Fig. 2, but such eye instead of being formed of a plate with
openings in it, consists of the said plate with a simple opening, and with two
studs or rivets firmly secured thereto so that the said eye may be manipulated in
attaching it to the steel blade to form a corset hook without danger of the studs
or rivets becoming detached.
It will be evident that the cutters or punches, feeding devices for the strips,
blank and wires, and heading devices may be differently constructed and arranged,
and with different appliances for operating them, but one construction and arrange-
ment embodying a machine which has proved to be extremely effective in actual
operation will now be described.
The frame A, of the machine has a base B, upon which is erected the standard
or support for the parts which must operate above the base.
There are two punches, one s, (Fig. 7) having two rods 2, 2, and a projection 3,
and the other t, (same Fig.) having a single projection 4, and both arranged upon
a cross head 5, of a reciprocating plunger 6, the parts 2, 2, 3, constituting the
punch for punching out the openings a, a, a, and the projection 4, constituting
the punch for punching out the blank, and these two punches are arranged one
beyond the other in line with the direction of feeding the strip X, as shown in
Figs. 4, 7, 9 and 10.
The said strip passes between two feed rollers 7 and 8, upon shafts 9, 10, Fig. 7,
and intermittent motion is imparted to the lower shaft 10, by means of a swing-
ing arm 12, (Fig. 4) carrying a pawl 13, engaging a ratchet 14, on the said shaft 10.
The punches pass through a perforated plate 15, Figs. 7 and 9, which plate is
supported in an elevated position to permit the strip X, to pass freely below the
same, and the punch 4, is longer than the punch 2, 3, see Fig. 7, so that as the
perforated blank Y, is punched from the strip, it is carried downward and into
a carrier slide C, having an opening adapted to receive the blank, see Figs. 7
and 10, and sliding laterally or in a direction at right angles to the line in which
the strip X, is fed. The carrier C, then moving to the position shown in Fig. 9,
brings the blank Y, with its openings a, a, in position to receive the ends of two
wires a, a.
In order to insure the retention of the blank in the carrier C, the
said carrier is severed at one end as at c, and when the blank is forced into
the opening thereof, its sides are forced slightly apart and bear frictionally upon
the edge of the blank.
The wires pass from suitable reels, and are fed upward between a pair of feed
rolls 16, 17, Fig. 8, upon shafts 18, turning in a strip 19, upon the base B, the
wires passing from the feed rollers upward tthrough holes in a die plate 20, upon
the face of which slide two gripper plates 21, 22, connected respectively to sliding
blocks 23, 24, see Figs. 8 and 10. The opposing edges of the gripper plates are
notched to receive the ends of the wires a, between them, the notches being slightly

page_text: flared or bevelled at their upper ends (see Fig. 10) to upset the pins upon the lower
side of the blank, and the said plates are carried first to a position to grip the
wires as they rise through the die plate 20, see Fig. 10, and then they are moved
together laterally in the direction of the arrow w, Fig. 10, thereby shearing off
the projecting ends of the wire, forming two pins which are carried to a position
beneath the holes r¹, r, of the blank Y, see Fig. 10, which shows in full lines
the first position of the gripper plates in gripping the ends of the wires, and in
dotted lines, the position to which the pins cut from the wires are carried. The
carrier C, and its contained blank Y, are brought into position to receive the
ends of the wires a, a, before the lateral shifting of the wires has been completed
and as the ends of said sections extend above the plane of the lower face of the
carrier, it is necessary to form recesses c¹, cl, Fig. 14 in said face to permit the
wires to be moved beneath the blank Y, in alignment with its openings ¹, 21.
The block 23, Fig. 8 which carries the gripper plate 21, is reciprocated by a
lever 25, oscillating on a pin 26, and the block 24, is moved in one direction by
a spring 27, which bears upon a pin 28, sliding in a hollow set screw-block or
sleeve 29, and bearing against one end of the block 24. The spring 27, carries
the block 24, towards the block 23, and yields to permit the gripper
plate 22,
slide in the direction of the arrow 20¹, when the
gripper plate 21, is moved in that direction and when the block 24, is in
the position shown in Fig. 8, after the pins have been transferred to a position
below the blank, the block is held in that position by a lock bolt 30, which
descends into an opening in the block.
to
The pins having thus been brought to proper position the heading die F,
descends. This die is carried upon a plunger 6, Figs. 8, 11, 12, sliding in guides
and connected by a rod 43, to a crank 44", of the shaft 42 and has a central
plunger 31, which bears against a spring 32, and which by its contact with the
blank forces the latter downward to the bottom of the opening in the carrier and
onto the gripper plates 21, 22, and then the annular die F, by its contact with
the ends of the pins spreads and heads the latter, upon the upper side of the blank
and forces a portion of the metal of the studs into the flared ends of the notches
of the gripper plates to form heads upon the opposite side of the blank.
After the pins have been headed and riveted to the blank as aforesaid, the
carrier C, moves back to carry the blank over a discharge opening v, Fig. 11, and
a plunger 36, then descends and pushes the blank from the carrier into the
opening through which it drops to a suitable receptacle. Inasmuch, however, as
the carrier C, cannot move back while the pins are in the recesses in the edge of
the plate 22, the carrier C, is swung laterally sufficiently to carry the ping out
of the recesses. To effect this, a plate 35, bolted to the sliding block 23, see
Figs. 9 and 10, carries a bolt 40, pushed forward by a spring 41, and which when
the block 23, is carried back after the heading of the pins, makes contact with
the edge of the carrier C, and swings the latter in a direction to carry the pins
out of the notches in the plate 22.
To prevent the blank when it is cut from the strip and carried by the punch s,
into the socket in the carrier C, from being pushed through the said socket, a
sliding gauge pin 37, Fig. 12, is provided, which slides in a vertical recess in
the bed-plate B3, below the punch s, and which is connected to an arm 38, upon
a sliding rod 39, and which is raised into the socket in the carrier as the punch s,
descends and thereby gauges the position of the blank.
The parts above described are all driven through the medium of any suitable
appliances from a driving shaft 42, rotating in bearings in the frame A, and
carrying a balance wheel D. The plungers 6, 6, slide in suitable guides and are
connected by rods 43, 43, to cranks 44, 44%, of the shaft 42 and are thereby
reciprocated at the proper times. The carrier C, is connected to a slide C', having
a roller projection 45, Fig. 3 which enters an annular slot u, in a plate 46, con-
nected to a bar 47, sliding in suitable guides and connected by a rod 48, with
the crank of a crank wheel 49, upon the shaft 42.

page_text: The block 23, is reciprocated by the vibration of the lever 25, which carries
a roller that bears upon a cam 149, Fig. 8, on the shaft 42, that swings the lever
in one direction, while a spring 50, pulls it, in the opposite direction.
As stated, the locking pin or bolt 30, locks the block 24, in its position during
the heading of the pins when the heading die F, descends. When the heading
die rises, a lug 51, extending from the plunger 6, makes contact with a collar 52,
on the bolt 30, and lifts the latter against the stress of a spring 53, which carries
the bolt downward when the plunger next descends.
The shafts 9, 10, of the feed wheels 7, 8, are geared together by gears 58,
Figs. 6 and 9, and the feeding arm 12, Fig. 4, is reciprocated from a cam 54, on
the shaft 42, which bears on the end of a lever 55, connected by a rod 56, to the
said arm 12. The cam acts to lift the rod 56, a spring 57, moving the rod in the
opposite direction.
The wire feed wheels 16, 17, Figs. 8, 11, 12, carried by the shafts 18, are geared
together and upon one of the shafts is a ratchet wheel 59, with which engages
a pawl 60, Fig. 5, upon a rocking arm 61. The arm 61, is carried in one direction
by a spring 62, but is vibrated to turn the feed wheels to lift the wires by the
contact of a cam 63, carried by an arm 64, extending from the plunger 6.
The discharge plunger 36, Fig. 3 is upon an arm 66, Fig. 4 extending from a
rod 75, upon the upper end of which bears the end of a lever 67, which is
depressed by a toe 68, Fig. 5 on the shaft 42, which makes contact with a
horn 69, on a shaft 70, carrying the lever 67; a spring 71, Fig. 3, bearing against
the lower end of the rod 75, and tending to elevate the same. The slide rod 39,
which carries the gauge 37, has a roller at the top which engages with a
cam 78, on the shaft 42.
If the stock strip terminates and no material is continued to be fed to the
machine, it is desirable to have the latter at once cease its operations. A stop
finger f, Fig. 6 or other suitable stop actuating device is provided, which bears
upon the strip and is held thereby in one position and which moves to another
position as soon as the strip passes from the same, and. combined with this stop
device, are any suitable appliances which will be operated therefrom to arrest
the machine. As shown in Fig. 6, the finger f, projects from an arm 80, on a
rock shaft 81, Figs. 5 and 9, and on the end of the shaft 81, is an arm 82, which
is drawn by a spring 83, towards one arm of a lever 84, pivoted to the side
frame. The opposite arm of the lever has hook 85, which engages a notch in a
sliding rod 86, having at the upper end a curved cam 87, which may be thrown
by a spring 88, towards a collar 89, secured to the shaft 42. Normally the
collar 89, is locked to the band wheel D), by a bolt 90, which slides in the collar
and enters a recess g, in the band wheel. When, however, the finger f, drops
and disengages the hook 85, on the rod 86, the cam 87, is thrown upward, when
a pin 91, extending from the bolt 90, will be brought against the bevelled end p,
of the cam 87, and the bolt will be shifted as shown in Fig. 13, to withdraw it
from the band wheel D, which then turns loosely upon the shaft, and the pin 91,
strikes a face r', of the cam 87, and at once arrests the further rotation of the
shaft. In order to start the machine, the rod 88, may be drawn downward by
means of a treadle, not shown, connected to a rod 95, when a spring 96, will
force the bolt 90, laterally into the recess in the band wheel 1). The spring 96,
would be in the bolt 90.
In the machine about to be described and illustrated in Figs. 15-31, the same
general effect is ultimately produced, but by different mechanisms operating in a
different order from the machine just described, and while in this machine the
metal strip is fed to the punching devices, holes are formed in said strip, wire
sections are inserted in certain of said holes and secured therein to form the studs
and the sections are then cut out of the strip to form the complete article having
the studs therein.
.
1, is the frame of an ordinary power press which is well adapted for blanking
and studding eyes for corset steels. 2º, is the vertically movable gate. In an

page_text: ordinary press the gate is operated by a crank shaft and pitman but in this
instance the gate, is, necessarily, operated in a different manner to effect the
result sought to be accomplished. Figs 15, 17 is a yoke having a circular
central portion or swell that embraces the driving shaft 4".
The lower part 3b, of this yoke is secured to the gate by screws 5°, while the
upper end 3°, is movably secured by the cap 6", to the upper part of the frame of
the press.
7, is a bolt whose threaded portion engages the yoke, while the
head of such bolt engages with the forked lug 8b, on the gate 2". This bolt still
further secures the yoke to the gate.
9, are rolls mounted upon the short shaft 10", of the yoke brackets 11ª. These
rolls engage with the cams 12ª, 12b, mounted upon the driving shaft 4". This
arrangement of the rolls and cams elevates the gate, while the central cam 13",
engages with the roll 14, to depress such gate. This roll 14, is journalled on
a pin between the ears 15*, of the forked extension, integral with said yoke.
15b, is a threaded stud in the gate, having the head 16 and nut 17, whereby
the yoke, with the roll attached, is vertically adjusted, which arrangement also
adjusts the position of the gate with respect to the die block, presently to be
described.
18ª, is the wire feeding slide vertically operating in the ways 19", on the face
of the gate. This slide has an independent movement on such gate through the
medium of the lever 20", and vertical face of the cam 12h, on the driving shaft 4".
On the face of the cam is the wedge shaped step 20 Fig. 15, that engaging the
head 20°, of lever 20°, will both operate to tilt such lever on the pivotal screw 21ª,
and force it vertically downward as well. The retractile spring 22ª, Fig. 16, will
return such slide to its normal elevated position. 23, is a gripping jaw on the
lower end of the lever 20*, having a circular groove in its face for the wire 24°.
In this machine two wires 24 and 25", are fed down, for the purpose presently
to be more fully described. 26", is the stationary jaw having a grooved face
similar to the face of the movable jaw. 27, is a spring tongue whose head 28",
has grooved faces to embrace the two wires 24 and 25". These wires are
delivered from a reel, not shown, and pass between the faces of the jaws 23",
and 26, and the head 28, of the said spring tongue. The first effect of the
cam 12, will be to move the lever 20%, laterally which will close the jaws 23ª,
upon the wire 24, and under this lateral pressure the spring tongue will be
forced toward the stationary jaw 26", thus gripping both wires through the
medium of one movable jaw. The next operation performed by the cam 12,
will be to force the slide 18, down carrying the said wires with it. 29* Fig. 18,
is an adjusting screw in the top of the slide 18%, to limit its upward movement,
by such screw striking against the upper wall 29, of the recess in which such
slide operates.
30° Fig. 20, is the tool holder which fits the dovetail opening 31, Fig. 18, of
the gate. 32, are two small punches for the stud holes 33, Fig 31 in the corset
eye, and 34, is the punch for the key hole slot 35, Fig. 31, while 36", is the
blanking punch which blanks the completed corset eye 37, Fig. 31, from the
metal strip. 32, are screws for adjusting the punches 32.
38 and 39, Figs, 21, 22, 25, 26-28 are the stud blank carrying slides operating
from the front and rear of such holder towards the centre, semicircular grooves
are provided in the meeting faces 40, 41* of such slides to embrace the wires 24",
and 25. The inner ends or fingers of these slides are thinner than the body
portions which slide in the ways 42 and 433b, of the tool holder. The thickness
of these fingers is equal to the length of the studs 44 and 45", which project
from the metal strip 46*, and such fingers are also hardened.
47, Figs. 25, 26, 27 is a plate which overlies the wires on the end of the tool
holder and 48, Figs, 20, 21, 22 is a clamp whose upper end is pivotally supported
to the bracket 49, while its free end has the right angle projection 49b, which
projection or finger enters the elongated slot 50 of the plate 47, and such finger
is adapted to engage the wires and hold them firmly against the tool holder when

page_text: the wire-carrying slide 18", is retreating to grip the wires further up for another
downward feed. 51, Fig. 16 is a lever whose finger 51b, engages the outer face of the
clamp 48, while the free end of such lever engages the face of the cam 52",
which lever operates to force the said clamp against the wires, and 48b, Fig. 20,
is a spring interposed between said clamp in an open position, which spring
serves to keep such clamp against the finger 51b. 53, Figs. 21, 22 is an anvil
in the tool holder whose purpose will presently be more fully described.
54, is a plunger that enters a hole in the outer end of the stud blank carrying
slide 39, and 55, is a spring placed at the bottom of such hole to act against
the inner end of such plunger to force it out. 56", is a cam mounted on the
rod 57, of the bracket 58, which bracket is attached to the end of the tool
holder, as shown. 59, is an arm on the outer end of the rod 57* which is
pivotally connected to the operating lever 60" pivoted in the ears 61", of the
press gate. The upper end of this lever carries the roll 62, which engages with
the cam 63, on the driving shaft 4. The cam 56, is designated as the release
can and its purpose will, hereinafter, be more fully described. 64, is a lever
pivoted between the ears 65, of the press gate whose upper end is brought in
contact with the cam 66. The lower forked end of the lever embraces the pro-
jecting pin 67, of the slide 38, to operate such slide.
68, Fig. 30, is the die block having the usual strippers 69 and 70° over-
lying the dies in said block. 71 and 72* are feed rolls in the frame 73ª.
74, Fig. 16 is a ratchet wheel mounted on the outer projecting end of the roller
pin 75 and 76", is a lever also pivotally supported on such pin and which lever
carries the pawl 77", which pawl engages with such ratchet wheel. Rod 78*,
connects the outer end of this lever with the crank plate 79, mounted on the
outer projecting end of the driving shaft 4°. This arrangement of the said rod,
lever, pawl and crank plate, feed the metal strip forward to the dies.
Any suitable arrangement of devices may be employed for heading the studs
upon opposite sides of the metal strip, but preferably it is desired to employ parts
upon each side of the strip which may be actuated to either be simultaneously
reciprocated towards each other or be actuated to reciprocate simultaneously in
the same direction, to co-operate and head or upset the stud upon opposite sides
of the metal strip. Those heading devices which have been shown are actuated
to reciprocate simultaneously towards each other.
80, Figs. 22, 23, is the header which is mounted on the lever 81", which lever
is pivotally mounted upon the standard 82%. The outer end of this lever is engaged
by the vertical rod 84, supported in the bearings 85", Fig. 16 of the press
frame. The upper end of this rod engages the cam 86, whereby the lever 81°,
is tilted. A hole is provided in the die block for the larger portion or body of
the header 80%, and also, smaller holes to receive the two uprights 87°. These
uprights are intended to support the ends of the stud blanks that project through
the metal strip and to head the same in the manner presently to be more fully
described. 89, is a nut mounted on the lower threaded end of the rod 84", to adjust
the position of the header 80", in the die block. 90%, is a retractile spring to keep
the rod 84, against the face of the cam.
The tools of the press, are in a raised position and the first
movement in the operation of blanking and studding will be to close
the movable jaw 20", and firmly grip the wires in the manner
before mentioned. Next the wire feeding slide 18", is moved down-
ward so as to project the ends of such wires below the lower face of the
tool holder, when the gate 2, will move down until such projecting ends of the
wires are brought close to the metal strip, whereupon, the slide 38°, is moved
forward to engage such projecting ends, which ends, by reason of the resistance
offered by the slide 39*, are held firmly between the fingers 38 and 39b, of such
slides, it being understood, but not shown, that two grooves for the wires are
formed in the longitudinal face of the anvil 53, thus making a combined anvil
and cutting off die so that, when the slide 38*, continues to advance, it will cut

page_text: off two sections of the wire, and force the slide 39º, back until the severed ends
or stud blanks are carried over and against the end of the anvil 53ª, and on a
line with the holes 33*, in the metal strip, which holes, as previously mentioned,
were made by the punches 32ª, whereupon, the said slides will halt until the
gate 2, descends toward the die holder, forcing the ends of the stud blanks,
that project below the fingers of the slides, into the holes 33, of the metal
strip, and also far enough through such strip to head. In the meantime the
projections 87, of the header 80%, have been carried up into position close to
the underside of the metal strip. The downward pressure of the gate, with the
upper end of the stud blanks resting against the projections 87, of the header and
anvil 53, of the tool holder 30, will not only form the heads 44 and 45b Fig. 28,
but will also form the shoulders 44°, and 45°, on the upper side of the metal strip,
thus firmly securing the studs both on the upper and the lower side of such strip.
It will be understood that, to form the heads of the studs, the ends of the projec-
tions 87, of the header are cupped out sufficient for that purpose, while the side
pressure of the hardened fingers 38 and 39b, of the slides, combined with the
downward pressure exerted by the gate will cause a lateral enlargement of the
stock to form the upper shoulders 44° and 45°. To make room for these shoulders
so they will be flush with the upper surface of the metal strip. It is preferred
to make the shoulders 32b, of the punches 32, slightly convex, so as to form the
cup shaped depressions 33b, around the upper ends of the holes 33ª.
When the operation, above mentioned, is completed and just before the gate
retreats, the cam 56, is turned so as to present the lowest point to the end of
the plunger 54", which will relieve the pressure or grip of the slide finger 39b,
on the studs so that the slide 39%, may return to its normal position with the
slide 38%, or, in other words, both slides will return together. It will be under-
stood that, at each revolution of the driving shaft 4, the stud holes 33, key-hole
slot 35, are pierced and the studs are cut off, forced and riveted in the previously
formed holes in the strip and the corset eye 37°, clamped from the metal strip.
Holes 36b, Fig. 20 are provided in the face of the blanking punch 36, to admit
the studs while said punch is operating on such metal strip.
When the wire-feeding slide is about to retreat, the clamp finger 48, will be
brought into engagement with the wires 24 and 25, and hold them firmly in
the tool holder block so as to prevent a retrograde movement of such wires."
Heretofore it has required several preparatory machines before corset eyes
could be made and attached to the corset steel. First, the eye was pierced and
blanked, and the rivets made separately and inserted loosely in such eyes by
means of an assembling machine. This manner of constructing corset eyes and
similar work was not only expensive by reason of the many operations and hand
manipulation, but the loss of the small parts added considerably to the cost.
In the improved machine the eye is completed and the studs securely attached
thereto in one machine, so that the matter of riveting such eyes, or other like
article, by means of the studs to the corset steel is a very simple and inexpensive
operation.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondents, I declare that what I claim is:
1st. In a metal blanking and studding machine for producing corset eyes as
