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 and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:.
This invention has relation to eye-letting-machines provided with devices under
the control of the operator, for moving the punch and its bed away from the point
where the eyelets are inserted, to increase the space between the holes, and means
for arresting the feeding of the eyelets, and causing the holes not supplied with
eyelets to be made at a greater distance apart than usual, for the reception of
lacing-studs or hooks.
The object of the present invention is to provide a machine of the type referred
to with adjusting means for increasing or decreasing the distances or spaces
between the holes for the eyelets, and the greater distances or spaces for the studs;
or in other words, the object is to provide means for varying the position of the
punch relatively to the lower set when it operates to punch a hole, and for varying
the limits of the path of movement of the upper set, whereby the holes for the
eyelets, as well as those for the studs, may be formed nearer or farther away from
each other.
Another object of the invention is to provide the machine with means under the
control of the operator, for effecting the increase or decrease of the space
between the holes without loosening any screws, and by merely shifting a lever
to one side or the other; to equip the machine with devices also under the control
of the operator, for withdrawing the race way from the eyelet-sets when holes are
being punched for the studs or hooks; and to automatically shift the adjusting
devices after the wider-spaced holes for the studs have been made, to cause the
formation of the shorter-spaced holes for the eyelets.
It is the object of the invention, likewise, to provide a machine with additional
improvements whereby it will be rendered highly efficient in operation, easier of
adjustment, and simpler in construction.
To these ends, therefore, the invention consists in a machine having those
features of construction and arrangement which I shall now proceed to set forth in
detail, and then point out in the claims which are appended hereto.
Reference is to be had to the accompanying drawings, forming a part of this
specification, and to the letters and figures of reference marked thereon, the same
reference characters indicating the same or similar parts or features, as the case.
may be, wherever they occur.

In the drawings,—
a represents the supporting frame of the machine, having a vertical bearing b,
in which is journalled a stud c, provided at its upper end with a head d, in which
is pivoted at e the top set-lever f. To one end of the lever f is secured the
top set g, the other end h of said lever projecting through a wide yoke in
the upper end of a vertically movable bar mounted in bearings at the end of the
frame. The cross-aperture in the yoke i is considerably wider than the end h
of the set-lever, so that the said lever may oscillate on the stud c relatively
thereto.
kis the power-shaft, which is suitably journalled in bearings in the frame a,
being provided on its end with a loose belt-pulley m adapted to be connected there-
with by a clutch n. On the shaft is rigidly secured a disk o, having a cam-
groove to receive a roller p on the end of the vertically movable stud or bar j.
When the shaft k is rotated, the bar will be reciprocated vertically, as will be well
understood. The end of the top set lever is provided with a spherical knob q,
and between said knob and the upper and lower walls of the yoke I place cups r,
or sliding pieces having concave faces to receive the knob q. The yoke is arranged
at a tangent to the path of oscillation of the lever f, so that when the lever is
reciprocated, the ball or knob 2 will move perfectly in its cup-like sockets or
bearings r, irrespective of the position of the set-lever relatively to the yoke.
The bar t
On a brackets extending out from a collar h¹ on the stud c, I bolt the punch-
block bar t, which has at its front end a punch-block or abutment u.
is stationary vertically, and is provided at its rear end with upwardly extending
ears v, in which is pivoted the punch-bar or lever w, the bar t being also provided
with guides a for the front end of said lever. The front end of the lever wis
provided with a socket to receive the punchy, suitably held therein by a set-
screw 2. In the rear of the punch y, the lever wis formed with a through
aperture a¹ to receive a block 61, having its end connected to the forked arms c¹
of a reciprocating bar d³, the latter moving in a bearing e¹ and being actuated by
a disk having a cam-groove into which a roller g¹ on the end of the bar ď
extends. The cam-grooved disk f¹ is suitably secured to the driving-shaft k, by a
pin or otherwise.
The top set-lever co-acts with a vertically reciprocated lower set-bar 2, which
latter is guided in bearings on the frame, and is actuated by a cam ¹. The
lower set is suitably mounted in its bearings, and held therein by a screw m¹.
I so connect the punch-bar or lever, and the top set-lever, that they are moved
in unison about the stud c, providing devices whereby the distance to be traversed
by them will be varied in accordance with the distance to be left between the holes

page_text: formed by the punch, and also devices for adjusting the punch-bar lever and the
top set-lever relatively to each other.
It is of course understood that in operation the punch-bar is actuated to punch
a hole in the upper, and is moved back out of the way to permit the top set-lever to
be moved down to enter the hole cut by the punch, and to move laterally so as to
feed the whole upper laterally until the top set is in line with the lower set, when
they are actuated to set an eyelet in the hole. Hence when it is desired to leave a
greater space between two holes in an upper, the punch must form a hole at a
greater distance from the lower set, and therefore the upper set-lever must traverse
a greater distance in feeding the upper to the lower set; and it is also necessary
that at the end of the movement of the upper set it should be exactly in alinement
with the lower set, which latter is stationary, in order that they may co-act properly
in setting the eyelet.
In addition to these devices, I also provide a mechanism for limiting the path
of oscillation of the top set-lever and the punch-bar, and for varying it to suit
the particular occasion, all as I shall now explain.
In a bearing m¹0 bolted to the side of the frame, I mount a vertical rock-shaft n³,
having on its lower end an arm o', with a roller p¹ lying in a cam-groove q¹ in
the disc o, so that when the disc o is rotated, the shaft n will be rocked or oscillated.
The upper end of the shaft n' is provided with an arm r extending at right angles
to the arm o¹, and connected by a link s with a slide-way t pivoted on the
vertically reciprocating rod j. The head d of the stud c is extended out in two
bars v', to form upwardly extending cars or guides u¹ for the top set-lever f, and
below the bars is a slide w¹, which has a portion extending down into the slot y
in the slide-way t 2 is a small plate secured to the portion a¹ of the slide and
extending under the slide-way, so as to hold the slide in place. Now it will be
seen that when the rock-shaft n¹ is rocked, it will, through the arm and the
link s, oscillate the slide-way t, and through the medium of the slide w¹, oscillate
the top set-lever f on the stud c. Arranged beneath the bars ¹ extending out from
the head d, is a plate a², having a curved slot 62, which is eccentric to the stud e
and at an angle to the top set-lever f; and extending down into said slot 63
is a pin 2 secured to the end of the punch-block bar t. The slide w¹ is connected
by a link with a lever e pivoted on the vertical shaft j. The plate a has
a rectangular portion f2 extending up between the bars ¹, so as to slide therein,
and is apertured at g2 to receive a pin 2 projecting up from the slide ¹. Thus
it will be seen that the abutment-block bar and the punch-lever are connected
with the top set-lever, so as to move therewith. When the lever e2 is rocked
around the shaft to the left (see Figure 3), it will, through the link ², force the
slide w away from the shaft j, carrying with it the plate a², so that the walls of the
slot 62 will force the pin 2 away from the top set-lever f, causing the abutment-
block bar and the punch-lever to be swung around the stud e relatively to the top
set-lever. This will increase the distance to be traversed by the top set-lever, as
well as that traversed by the punch-bar.
The path of oscillation of the slide-way being uniform, it will be readily seen
that by moving the slide w away from the center of oscillation, the slide will
traverse a relatively greater distance, and will therefore cause the top set-lever
to be moved a greater distance; and by drawing the slide toward the pivot of
the slide-way, the said slide will traverse a relatively shorter distance, and
thereby cause the top set-lever to traverse a shorter distance.
The lower set is stationary laterally, and the top set operates to feed the upper
to the lower set after the hole has been punched in, as has been described. Hence
when a greater distance between the holes is desired, it is necessary to punch a hole
farther away from the lower set, and therefore the top set-lever must traverse a
greater distance in feeding the upper along to the lower set, the punch-bar or
lever also travelling a relatively greater distance. If the top set-lever and the
punch-bar were made to travel a greater distance, or move in a longer are, without
varying the positions of the same relatively to each other, it would follow that the

page_text: upper set would not properly engage in the hole made by the punch; or in other
words, the rearward limit of movement of the top set would not be in alinement
with the forward limit of movement of the punch; and hence when it is necessary
to effect a longer throw of the top set, it is also necessary to adjust the punch-bar
relatively to the top set, so that when the punching action takes place, it will be
exactly the point at which the top set descends to engage the hole. This adjust-
ment of the punch-bar relatively to the top set-lever is effected by the pin &
travelling in the slot 63 in the plate a², the slot being at an angle to the set-lever,
so that when the slide and the plate a² are moved forward to increase the arc of
travel of the set-lever, the punch-bar and the abutment-bar are swung slightly
around the stud e, so as to cause the punch-bar to make a hole in the upper in that
line, to which the top set and the lever f will be moved. The end of the path of
movement of the top set in its forward direction is in alinement with the axes of
the stud c and the shaft j, the cam slot q' being so curved as to effect this, the
lower set being in that line and being stationary. Hence when the lever e² is thrust
to the right, in Figure 3, it draws, through the medium of the link d²; the
slide w', and the plate as, toward the shaft j. This movement causes the top set g to
move slightly laterally, or forward, toward the lower set, and the pin sliding in
the slot in the plate a² will move the punch y nearer to the set g, as will be
clearly seen. Thus the movement of the lever es automatically increases or
diminishes the path of movement of the set-lever, and adjusts the punch-bar
relatively to the said lever.
By referring to Figure 5, it will be seen that I have provided lever e³ with a
sliding dog, having its front end serrated to engage the serrations gª on a
sector-shaped plate 2. The dog or latch faslides on suitable guides, and is
provided with a recess, having inclined end walls is a thumb-lever
pivoted on the under side of the hand-lever and having its pivot m² cut away to
form a semi-cylindrical cam which, when it is rocked, will have its periphery in
engagement with the inclined walls or respectively. When it is desired to
slide back the latch fa from the serrations g², the thumb-lever 18 is pressed toward
the lever c, and the cam-like pivot m2 engages the end wall of the recess and
draws the latch back, so that the lever can be moved to the right or to the left.
On the sector-plate ³ I place an adjustable gage, to limit the movement of the
levere. The gage is conventionally illustrated, as consisting of two pins o² på
adapted to be inserted in any of a series of holes q³ in the said sector-like plate.
By means of these pins, the amount of adjustment of the top set-bar and the
punch may be limited. In order to adjust the setting and punching mechanism
relatively to the cam g', I place in the aperture 73 in the arm 1 an eccentric
sleeve s², to receive the pivot-pin 22 which connects the links with the arm r¹.
By adjusting the position of the cam-sleeve, the link s and the arm r¹
adjusted relatively to each other.
may be
In addition to causing the formation of holes at a greater distance apart than
those first made by the punch for the reception of the eyelets, it is desired to
prevent the eyelets from being fed to those first-mentioned holes, since it is desired
to place in them studs or hooks. Hence I shall now describe the raceway for the
eyelets, and the mechanism for preventing the eyelets from being fed to the said
holes.
2 is the raceway through which the eyelets pass from the hopper w³ and the
receptacle. The raceway and the hopper and receptacle may be of any approved
pattern, since I do not limit myself to the employment of any particular kind.
The support y for the raceway is pivoted at 2 to a plate a³, the latter being itself
pivoted upon a shaft 63 supported by the frame a of the machine, and extending
through to the other side of the same. The plate a³ has an arm 3 extending
downward and provided with an inwardly projecting roller, lying in the cam-
groove ³ in a cam-disk e³. f³ is a link pivoted to the support y² for the raceway,
and pivoted to the frame a. When the cam-disk eis revolved, the pin in the
cam-groove will cause the oscillation of the plate a³ about the shaft 63, and a

page_text: consequent reciprocation of the raceway toward and from the set, as will be clearly
seen. About the pivot g³ for the link f³ is placed an eccentric sleeve h³, which fits
in the circular aperture 23 in the link 3 By turning the sleeve,
which is formed with a polygonal flange for this purpose, the link f³ may be
adjusted vertically, so as to raise or lower the end of the raceway toward and from
the work-plate 3, as will be understood.
In forming the holes for the reception of the eyelets after the hole is punched,
the top set enters into it and moves the work along into the path of the lower set,
as has been stated. As the lower set ascends, it engages an eyelet in the end of
the raceway, which has been moved forward, and the two sets firmly bind or secure
the eyelet in place; but when the holes are formed in the upper for the reception
of the studs or hooks, which holes are at a greater distance apart than those formed
for the eyelets, I provide means for throwing the raceway back, so. that when the
lower set rises, it will not engage an eyelet therein. The mechanism for
accomplishing this is as follows:-
The shaft 3, upon which the plate a³ is mounted, is provided with a crank, on
which said plate a³ is pivoted. The other end of the shaft is provided with a bell-
crank lever having two arms 13 and m³. The arm 3 is connected with a treadle
below the working bench (not shown), by a link n³. Hence when it is desired to
move the raceway back from the lower set, the treadle is depressed, rocking the.
shaft 63, and consequently dropping the plate a3 and the support y² for the
raceway 2, thus moving the end of the raceway out of the path of the lower set.
At the same time, I desire to automatically shift the lever e² forward, so as to
increase the path of motion of the upper set, and hence I connect the arm m³ of
the bell-crank lever by a link o³ with an inwardly extended arm p³ forming a part
of the thumb-lever 12. When the treadle is depressed, it draws upon the arm p
to turn the pivot m³ and draw the latch back from engagement with the sector-
plate, and finally swing the lever e² forward, until it engages the pin o³. After
the holes for the studs have been formed in the upper, pressure upon the treadle
is removed, and a spring draws the arm of the bell-crank lever upward, and
a spring interposed between the lever e³ and the sector-like plate h2 throws the
lever backward into its original position.
