page_text: We, THOMAS WEARDEN, of 559, Oldham Road, Newton Heath, Manchester,
in the County of Lancaster, Mechanic, and EDWARD PENNINGTON, of
595, Oldham Road, aforesaid, Clerk, do hereby declare the nature of this invention
to be as follows:-
-
Our said invention relates to improvements in eyeletting machines for eyeletting
leather, and other material as is well understood.
In a machine constructed in accordance with our invention we provide a
bracket capable of sliding in suitable ways formed in the frame of the machine.
This sliding bracket carries the usual die and clencher" and in addition is
provided with suitable ways in which slides a cam plate. Within the cam plate
are cut suitably shaped slots within which are disposed anti-friction bowls secured
to the usual vertically operating punch and plunger which reciprocate in suitable
bearings in the sliding bracket. The cam plate is connected to a disc by means of
a connecting rod.
The disc is suitably driven and under the control of the operator who is provided
with means for readily starting and stopping the disc. A suitable hopper carrying
the eyelets is hinged to the frame of the machine and the hopper carries the usual
eyelet carrier.
The eyelet carrier is also provided with a bowl working in a suitably shaped slot
in the cam plate.
The disc is formed with a cam groove with which engages a bowl carried by
the sliding bracket.
The material to be eyeletted having been placed on a table provided with the
usual or suitable guides the operator starts the machine. A quarter revolution or
thereabouts of the disc first operates the cam plate through the connecting rod
so as to slide the cam plate in the brackets and bring down the punch upon the
die, to punch the requisite hole in the material. The further revolution of the disc
raises the punch and by means of the cam groove with which the disc is provided
operates to slide forward the sliding bracket a distance sufficient to bring the
clencher under the hole punched in the material, and at the same time the
sliding bracket carries with it the cam plate so as to bring the plunger over the
hole. The plunger is provided at the lower end with a sliding pin capable of
being retracted within the plunger against the action of a spring. The disc
having moved through about half a revolution reverses the cam plate which operates
to depress the plunger. The initial downward movement of the plunger serves to

page_text: impale an eyelet from the bottom of the carrier upon the point of the sliding pin
carried by the plunger. The cam plate operates then to swing the hopper and
eyelet carrier upon the pivot and thus remove the end of the eyelet carrier so as to
provide for an uninterrupted descent of the plunger. On the continued descent of
the plunger the eyelet is carried by the sliding pin within the hole punched in the
material, which hole, as has been stated, is now disposed above the "clencher."
On coming into contact with the clencher the sliding pin is retracted against the
action of the spring within the interior of the plunger which descends upon the
eyelet and clenches it to the material. The punch and eyelet carrier are then
returned by the cam plate to their normal positions and the cam groove operates
to return the sliding bracket to its initial starting point.
The disc has then made a complete revolution and the cycle of operations may be
repeated. We provide the usual fixed plate through which the plunger passes,
so as to detach the material from the plunger on its upward stroke in case the
eyelet becomes jambed on the plunger.
We form the hopper with an inclined bottom and arrange a sliding plate to
agitate the eyelets until they assume their proper position for being fed into
the carrier.
The sliding plate is secured to the inclined bottom of the hopper by means of
studs passing through slots in the plate, springs being employed to obtain the
requisite degree of pressure of the sliding plate against the hopper. To reciprocate
the sliding plate we employ a bell crank lever mounted on a fixed stud. One end
of the bell crank lever is depressed on the descent of the plunger by a pin carried
on the plunger whilst the other arm of the bell crank lever is connected to the
sliding plate so as to reciprocate the same. A spring returns the bell crank lever
to its normal position on the ascent of the plunger.
The sliding plate works against suitable grooves formed in the hopper and as
the eyelets assume their proper position for being fed into the carrier they pass
along the grooves and fall upon an inclined surface, sufficient space being left
between the cover and the side of the hopper to enable them to fall and
maintain their proper position. A finger operated by the sliding plate pushes the
eyelets down the inclined surface to the mouth of the eyelet carrier. The opposite
side of the eyelet carrier is slightly raised to form an abutment to the eyelet
and enable it to drop into the carrier. If the carrier should be full the eyelets are
pushed over the abutment down an incline into an overflow receptacle.
We form the shute of the eyelet carrier with inclined sides, so that the eyelets
may readily pass down the same, the inclined sides preventing accumulation
of dirt.

Improvements in Eyeletting Machines.
We, THOMAS WEARDEN, of 559, Oldham Road, Newton Heath, Manchester, 4
the County of Lancaster, Mechanic, and EDWARD PENNINGTON. of
4, Hazel Grove, Longsight, Manchester aforesaid (late of 595, Oldham Road,
Mahester,) Clerk, do hereby declare the nature of this invention and in what

page_text: Our said invention relates to improvements in eyeletting machines for eyeletting
leather, card board and other material as is well understood.
The accompanying two sheets of drawings, to which we will refer, illustrates an
eyeletting machine made in accordance with our invention.
On Sheet 1.
Fig. 1 represents a side elevation of our improved eyeletting machine.
Fig. 2 is an end view thereof.
Fig. 3 is a plan and
Figs. 4 to 7 are detail views.
On Sheet 2.
Fig. 8 is a sectional elevation of the eyelet hopper and Fig. 9 a plan thereof.
In a machine constructed in accordance with our invention we provide a
bracket a capable of sliding in suitable ways formed in the frame A of the
machine. The sliding bracket a carries studs projecting through slots c (see
Fig. 5) in the frame A. Springs care coiled around the studs and confined
between two washers 2 by means of nuts so that the sliding bracket ais
maintained in elastic contact with the frame A of the machine. The wear of the
parts is compensated for by means of the nuts. The sliding bracket a carries
the usual die and "clencher" e the removable table n which is bolted to the
frame A being cut out as shown in dotted lines in Fig. 1 and in addition is provided
with suitable ways in which slides a cam plate f. Within the cam plate are cut
suitably shaped slots flf within which are disposed anti-friction bowls f³ft
secured to the usual vertically operating punch and plunger h which reciprocate
in suitable bearings in the sliding bracket a. The sliding bracket is formed
with a slot (see Fig. 3) to enable it to slide upon the driving shaft. The cam
plate f is connected to a disc by means of a connecting rod P.
The disc i is mounted upon the driving shaft driven by the pulley
control of the operator, who is provided with means for readily starting and
stopping the machine which means will be hereafter described.
hopper & carrying the eyelets is hinged at to the frame of the machine and the
hopper carries the usual eyelet carrier or shute 7.

The eyelet carrier is also provided with a bowl working in a suitably shaped
slot in the cam plate f
The disc is formed with a cam groove 2 with which engages a howl m carried
by the sliding bracket a.

The material to be eyeletted having been placed on the table which is provided
with the usual or suitable adjustable gauge, the position of the parts being as
shown in Fig. 1, the operator starts the machine. A quarter revolution or there-
abouts of the disc i, which revolves in the direction of the arrow, first operates
the cam plate / through the connecting rod so as to slide the cam plate f in the
sliding bracket a and brings down the punch upon the die d, to punch the
requisite hole in the material. This is effected by means of the bowl f secured
to the punch y sliding down the inclined portion of the slot f', the bowl ft sliding
idly in the straight portion of the slot f. The further revolution of the disc i
through another quarter revolution raises the punch to its initial starting point.
The disc i has now revolved through half a revolution and during this period
in which the punch descends, punches out the hole in the material, and again
ascends, the bowl m of the sliding bracket has traversed half the cam groove i¹
in the disc occupying during that period the smaller concentric diameter of the
groove. The sliding bracket a is thus motionless during this descent and ascent of
the punch g.
On the continued revolution of the disc i the bowl m changes into the larger con-
centric cam groove i¹ and operates to slide forward the bracket in the direction
of the arrow a distance sufficient to bring the clencher e under the hole punched

page_text: in the material and at the same time the sliding bracket a carries the plunger h
over the hole.
The plunger is provided at the lower end with a sliding pin / capable of being
retracted within the plunger against the action of a spring. The disc i having
now moved through half a revolution reverses the cam plate f which operates to
depress the plunger h by means of the bowl f* working in the inclined portion of
the shaft slot f
The cam plate f carries a plate o provided with an abutment of which on the
advance of the cam plate in the direction of the arrow comes in the path of the
bowl on the eyelet shute and swings the end of the pivotted eyelet carrier
below the plunger h. The initial downward movement of the plunger h serves to
impale an eyelet from the bottom of the carrier upon the point of the sliding
pin carried by the plunger h. The cam plate on its return movement by means
of the abutment operates then to swing the hopper and eyelet carrier upon
the pivot and thus remove the end of the eyelet carrier so as to provide for an
uninterrupted descent of the plunger. The eyelet is carried by the sliding pin h
within the hole punched in the material, which hole, as has been stated, is now
disposed above the clencher" e. On coming into contact with the clencher the
sliding pin his retracted against the action of the spring within the interior of the
plunger which descends upon the eyelet and clenches it to the material. The
plunger h is then returned by by the cam plate to its normal position and the cam
groove i¹ operates to return the sliding bracket a to its initial starting point.

The disc has then made a complete revolution and the cycle of operations may
be repeated. We provide the usual fixed plate or " detacher' through which
the plunger passes, so as to detach the material from the plunger on its upward
stroke in case the eyelet becomes jambed on the plunger. The detacher
adjustable for varying thicknesses of material.
is made
We pivot the plate o to the cam plate f so as to be able to turn the abutment of
out of the path of the bowl on the eyelet shute / as shown in the detached view
Fig. 4. This is done by slackening the milled nut o2 when it is desired to punch
holes only in the material, the eyelet carrier in such case is not advanced in the
path of the descending plunger h which thus works idle.
To adjust the stroke of the plunger to varying thicknesses of material we dis-
connect the driving pulley by means hereafter to be described so that it runs loose
upon the driving shaft. A hand wheel keyed upon the shaft is then revolved
until a mark engraved on its face is disposed opposite to a pointer q upon the
frame A (see Fig. 2). In this position the clencher is always at the bottom of its
stroke the disc i having made exactly three quarters of a revolution. The nut ris
then slackened so as to slide the pin of the connecting rod i in the slot 2 of the
cam plate f which cam plate can then be adjusted within the slide a so as to
regulate the descent of the plunger h to any required degree.
When the requisite adjustment has been attained the nut r is again tightened.
We form the hopper of the eyelet carrier with an inclined bottom and arrange
a sliding plates to agitate the eyelets until they assume their proper position for
being fed into the carrier.
The sliding plate s is secured to the inclined bottom of the hopper by means
of studs passing through slots in the plate, springs being employed to
obtain the requisite degree of pressure of the sliding plate against the hopper. To
assist in agitating the eyelets we form the bottom of the sliding plate s with a
projections. To reciprocate the sliding plate we employ a bell crank levert
mounted on a fixed stud t. One end of the bell crank lever t is depressed on the
descent of the punch g and plunger by pins carried on the plunger whilst the
other arm of the bell crank lever is connected by means of a link to the sliding
plate so as to reciprocate the same. A spring returns the bell crank lever to its
normal position on the ascent of the plunger. In Fig. 2 the bell crank lever is
shown depressed in full lines, and dotted lines indicate the position the sliding
plates s and bell crank lever assume when the end of the bell crank lever is raised.

page_text: The sliding plates is provided with suitable V notches and as the eyelets
assume their proper position for being fed into the carrier & they drop through the
notches and fall upon an inclined surface (see Fig. 2) sufficient space being left
between the cover and the side of the hopper to enable them to fall and maintain
their proper position. In Fig. 2 the cover is removed to show clearly the
incline v. A finger 2 shown in Figs. 2 and 9 operated by the sliding plate & pushes
the eyelets down the inclined surface to the mouth of the eyelet carrier 7. The
opposite side of the eyelet carrier is slightly raised to form an abutment to the
eyelet and enable it to drop. into the carrier 7. If the carrier should be full the
eyelets are pushed over the abutment down an incline into an overflow from
which they fall into a suitable receptacle.
To further agitate the eyelets we loosely pivot a finger wat wel in the eyelet
hopper (see Figs. 8 and 8) which is vibrated against the action of the flat spring
by the eyelets and serves to facilitate their assuming the proper position for passing
through the notches u.
The shuter of the eyelet carrier is formed with inclined or V shaped sides as
shown in Fig. 7 so that the eyelets may meet no obstruction in their passage down
the shute and to prevent any accumulation of dirt within the shute.
j
For readily stopping and starting the apparatus we mount the driving pulley j
loose on the driving shaft and key the same to the shaft when required by means
of a sliding key y shown in Fig. 6. This key y is adapted to engage with one of
a number of recesses formed in the driving pulley, and is operated as follows
A rod y (Fig. 2) controlled by the operator by means of a treadle (not shown) is
provided with a fork or prongs y². The rod y is thrust upwards by means of a
spring (not shown) and the prongs y² ride up an incline y in the wedge y and withdraw
the wedge or key against the action of a spring y allowing the pulley to run
loose on the driving shaft. When it is desired to start the apparatus the operator
depresses the rod y against the action of the spring thus withdrawing the prongs y
from engagement with the key y the spring y then thrusting the key forward as
shown in Fig. 6 so that the key engages with and secures the driving pulley to
the shaft. On the operator releasing the treadle the rod is thrust upwards and
disengages the key from the pulley as described thus stopping the machine. The
key can be held out of engagement if desired by means of the screw z engaging
with the recess z¹.
This clutch arrangement, we wish it to be understood, forms no part of our
invention and is not claimed by us as novel. Any other convenient clutch
mechanism may be used for starting and stopping the apparatus.
In cases where it is desirable to insert two eyelets at one operation such as in
calendars and the like we make the apparatus in duplicate, right and left so that
the punches and plungers are arranged centrally. Both machines are mounted
upon one bed and are adjustable towards and from each ether, and are driven from
a common source so that the movements of the parts sychronise.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. In eyeletting machines for eyeletting leather, cardboard and similar material,
mounting the punch and plunger to reciprocate vertically within a sliding bracket
operated by means of a cam, and actuating the punch and plunger by means of a
cam plate mounted to slide within the sliding bracket and operated by a connecting
rod and disc substantially as described and shown.
2. In eyeletting machines of the indicated nature a reciprocating cam plate ·
actuating the punch and plunger and vibrating eyelet shute, in the manner and
substantially as described and illustrated.
3. In eyeletting machines of the indicated nature an eyelet carrier consisting
of the pivotted eyelet hopper & carrying a sliding plate s actuated by means of a
bell crank lever from the reciprocating punch and plunger, and provided with a

page_text: reciprocating finger, the sliding plate being formed with recesses or grooves u
through which the eyelets drop upon an inclined surface and from thence into the
V shaped shute of the eyelet carrier Z substantially as described and illustrated.
4. The improved eyeletting machine for eyeletting leather card-board and
similar material, constructed arranged and acting in the manner and substantially 5
as described and illustrated.
