Improvements in Eyeletting Machines:
I, JOSHUA PUSEY, of 905, Walnut Street, in the City and County of Phila-
delphia, in the State of Pennsylvania, United States of America, Attorney at
Law, 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 main purpose of my invention is to provide a machine, or implement,
for fastening together sheets of paper, or the like, by means of ordinary
eyelets, in a more expeditions and convenient manner than heretofore.
The leading feature of the invention comprises the combination of two jaws,
one of which is adapted to be reciprocated to and from the other, or both
simultaneously; one of said jaws being provided with a pin, or punch, adapted
to receive thereon an eylet, such as are generally used with eyletting machines;
and the other jaw having a die-aperture, or female counter-die, registering with
said pin, but of such diameter that when the jaws are brought together-the
eylet being placed upon the pin-the end of the eylet, in conjunction with the
pin, will perforate papers, or the like, placed between the jaws, and the end of
the eylet and pin projected beyond the perforation will pass into said aperture;
and, whilst the eylet remains in the perforation so made, it may be set, or
clinched, by a suitable device for turning outwardly its protruding end, as
hereinafter described.
Another feature of the invention comprises devices or mechanism, whereby the
setting of the eylet may be readily and quickly effected without removing
the papers from the jaws of the machine, and whilst the eylet yet remains upon
the pin.
Other features of the invention relate to certain combinations and details of
mechanism designed to render the construction and operation of the machine as
simple, convenient and perfect as possible.
The precise nature and mode of operation of the invention and machine will
clearly appear from the following description, reference being had to the accom-
panying drawings, which illustrate a machine in which my improvements are
fully embodied and which I have put into practical use.
In the drawings,
Figure 1 is a side elevation, showing the parts in the normal position, for
perforating or punching operation;
Figure 2, a section on line, Figure 1;
Figure 3, a side elevation, showing the position of the parts at the completion
of said operation, part of the handles being broken off;
Figure 4, a similar elevation, showing the position at the completion of the
setting operation;
Figure 5, a section on line y-y, Figure 4:
Figure 6, an elevation of the side opposite to that shown in Figures 1, 3 and 4,
showing the stop device for limiting the movement of the sliding pin-carrier.

page_text: Referring now to these drawings, which represent my invention in the form of,
or applied to, parallel pliers of well known construction;-1 and 2 designate the
respective jaws which are reciprocated by working the handles, 3, in the usual
way.
The jaw, 1, has mounted thereon a part, 4,-hereinafter termed the "pin-
carrier and sometimes the "carrier," which is adapted to slide longitudinally
upon said jaw, and is maintained in place thereon by suitable guides, as, in the
present instance, by tongues 4ª, of the sides of the carrier, embracing the sides
of the jaw, in connection with corresponding grooves, 4, in the latter.
The carrier has a projecting pin, or punch, 5, that is loosely, but neatly,
fitted into a through guide hole, 5, in the carrier, so as to be capable of a certain
retractile movement, as and for a purpose hereinafter explained.
The inner, or in the position of the drawings, the lower end of the pin rests,
normally, upon, and so is rigidly supported by, the inner face of the jaw, as seen
in Figure 2 and indicated by dotted lines in Figures 1 and 3.
The pin is prevented from accidental escape outwardly from its guide-hole by a
suitable stop-device; as, for example, an enlargement, 5b, of the inner end fitting
a corresponding enlargement, 5", of that end of the guide-hole.

In the jaw, 2, is a female counter-die, 6, (hereinafter referred to as the die-
aperture") whose center is in line, or registry, with the center of the pin, 5:
and whose diameter-is-substantially equal to, or rather, slightly in excess of,
that of the eylet designed, or adapted, to be used with the machine.
The jaw, 2, is also provided with a suitable clinching or setting device, 7-
hereinafter termed the "setting head,"-for turning outwardly the end of the
eylet. Devices for this purpose being well known do not require particular
description.
In the jaw, 1, in line with or in registry with the setting-head, is a socket, or
opening, 8, Figure 5, and indicated by dotted lines in Figures 1 and 4-
whose diameter is at least equal to that of pin, 5, or rather, in this instance, the
enlargement, 5b, of the pin. In the construction shown, this opening is normally
covered by the forward part of the pin-carrier, it being thus covered in Figures 1,
2, 3, and 6. The extent of possible movement, or sliding, of the carrier is
limited by a suitable stop,-such, for illustration, as a longitudinal slot, 9,
Figure 6, in the side of the carrier and a screw, or pin, 10, in the jaw extending
into said slot, whereby, at one limit, pin, 5, shall be in registry with the
die-aperture, 6, as in Figures 1, 2, 3, and 6; and, at the other limit, in registry
with the setting head, 7, and also with the socket, G.
It is desirable that pin, 5, shall be maintained normally in registry with the
die-aperture (in position for the punching operation); and, to this end, I employ
a suitable spring acting upon the pin-carrier to tend to keep it at the first-
mentioned limit, yet permitting it, the carrier, to be moved forward to the
second limit. Such a spring, marked 11, is shown in the section, Figure 2,
and indicated by dotted lines in Figures 1 and 4; the same being a helical com-
pression spring lying in a groove, 12, sunk in the side of jaw, 1; one end of the
spring abutting against the forward end wall of the groove and the other end
against an inturned projection, indicated at 13, of the pin-carrier.
Within the socket, 8, is a plunger, 14, whose end, or head, 14", rests upon a
compression spring, 15, which is seated in the socket and tends to maintain the
head of the plunger about on a level with the top of the jaw (1); or, in the
present instance, what is practically the same, against the under side of the pin-
carrier, as shown in Figure 2 and indicated in dotted lines in Figure 1.
Having now described the construction, I shall proceed to explain the
operation, of the invention, as follows:-
The jaws being separated to the full extent by the hand-or preferably, by a
suitable spring, such as s, Figure 1,-and, the pin, 5, being in registry with the
die-aperture, 6, and eylet, e, whose external diameter is slightly less than that
of said aperture, and whose internal diameter is about that of the pin, is

page_text: slipped upon the latter; its flanged end resting upon the pin-carrier, as seen
in Figure 1.
The sheets of paper, P, or the like, to be eyletted, are now introduced between
the jaws; the latter are then brought forcibly together and so cause the compound
punch, composed of eylet and pin, to pass through the papers, as in Figure 3;
the punched out portion being forced out through the die-aperture, or by the
punchings of a succeeding operation.
I here remark, that it may be pre-supposed that, as eylets for uniting papers
and the like are made of thin and comparatively soft or yielding metal, the
eylet, instead of doing its part of the punching out, would crush down (unless
the body of papers were comparatively thin), but I found by numerous trials
that this difficulty did not occur. I was, in fact, surprised at the case and cer-
tainty with which the ordinary eylets perforated papers as much as a quarter inch
in thickness, with the machine shown in the drawings.
Returning to the description of the operation of the machine, the jaws are now
opened, leaving the eylet upon the pin, its end projecting through the papers,
and the pin-carrier is advanced, against the slight resistance of spring, 11, to
the limit of its forward movement, thus bringing the eylet and pin into registry
with the setting-head, 7, and also with the socket or opening, 8.
This movement of the carrier is most conveniently made in the form of the
machine shown-by drawing forward the papers, P, by one hand, whilst the
handles, 8, are held in the grasp of the other hand.
The jaws are now again forced together, whereupon pin, 5, will, by the contact
therewith of the setting-head, be retracted against the stress of spring, 15, a
certain distance (depending upon the length of the particular eylet and the
thickness of the papers) into the socket, 8, and the cylet will be finally clinched
by the setting-head, as seen in Figures 4 and 5. This accomplished, the jaws
are again opened, or permitted to be opened by the action of the spring, s, when,
pin, 5, being freed from socket, 8, by reaction of spring, 15, upon plunger, 14,
and the eyletted papers being then removed, the carrier will be retracted, by
spring, 11, to the original normal position of Figure 1, ready for a repetition of
the foregoing described operations.
As it is desirable that the parts apt to become dull from frequent use should
be capable of ready removal when necessary, I prefer to make the counter-die,
or die-aperture part, and the setting-head each a separate piece socketed in, or
otherwise detachably secured to, the jaw, 2, as suggested by the drawings; and
I also provide for removal of pin, 5, when required, by making the bottom part
-marked, 8, of the socket, S, detachable, as for instance, by screwing in the
same, as also indicated in the drawings.
Thus, first removing the part, S", the spring, 15, and plunger, 14, may be
taken out; and then, by bringing pin, 5, into line with the opening, it may be
removed, or allowed to drop out; when a new pin may be inserted in lieu thereof.
It is not essential although usually much preferable that a spring, or other
automatically operating device, shall be employed to return the pin, 5, to the
elevated position after completion of the setting operation, as that may be
done by hand, or by a positively actuated device, or by gravity, in which latter
case the upper jaw would carry the pin.
The machine may be made in various forms, either as parallel pliers, or as a
lever press, wherein the lower one of the jaws would be stationary; each form,
however, having embodied therein not less than the essential feature of the two
jaws, one thereof provided with the eylet-receiving pin, the other with the
die-aperture of suitably greater diameter than that of the pin, as hereinbefore
described, and in registry with the latter.
In lieu of using the movable pin-carrier, pin, 5. may be mounted directly
in a guide-hole in the jaw, 1, and the socket and spring, or other suitable device
for returning the pin to the normal or elevated position, may be connected to a
part attached to said jaw and adapted to be slid or shifted into the two

page_text: positions the one giving a rigid support for the pin, during the perforating
operation, the other permitting the retractile movement of said pin during the
setting operation.
In such arrangement, the other jaw, 2, would be provided with a suitable
sliding or movable part or carrier having a setting head, whereby the latter
could be brought into position over the die-aperture when the setting of the
eylet is to be done, and shifted out of the way in order to leave the aperture
free for the passage of pin, 5, and the eylet thereon, when the papers are to be
perforated.
Or, the said part, or carrier, may be provided with both die-aperture and
setting-head, either of which, as required, may be brought into registry with the
pin.
I remark that it is not necessary that the free end of pin, 5, shall be
bevelled, as shown, as it might be made flat; nor is it necessary that it shall be of
greater length than the eylet, the function of the pin being to maintain the
cylet in place and to afford it internal support when being forced through the
papers, &c.
I may further remark, as an obvious advantage of my device, that the eylet
constitutes, so to say, a new punch or cutter each time the perforating operation
is performed.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
