(Cl. 218-45)
This invention relates to eyeleting machines
in which mechanism is arranged to feed the work
position to prevent the work-feeding mechanism
from taking effect during the remainder of that
automatically one step after each eyelet has been
inserted, Such a machine is illustrated and, de
scribed in United States Letters Patent No.
2,300,499, granted November 3, 1942, on appli
cation of S. L. Gookin. ,It is to be observed that
the category de?ned above excludes those ma
chines in which the work-feeding stage of each
cycle occurs prior to the eyelet-inserting stage
of the same cycle. The reason for this distinc
tion is hereinafter explained.
Now, with regard to the distinction mentioned
I in the ?rst paragraph, a machine of the other
category, in which the work-feeding step of each
cycle occurs prior to the eyelet-inserting stage,
is. outside the scope of this invention because
the feeding step of the ?nal cycle is necessary
to place the work in the correct position to re
ceive the corresponding eyelet.

including, the clutch-controlling means, the

or the normal stopping of the machine. The net
result of such prevention is that an eyelet will
be inserted, but the work will not be fed in the
?nal cycle, regardless of the number of cycles
in a run; but if a run includes more than one
cycle, the ‘work will be fed in each cycle except
the last.
As herein illustrated, the controllable means
for preventing the normal operation of the work
feeding mechanism is coupled with a manually
movable controlling member of a clutch-and~
brake assemblage of a well-known type. These elements are so related that no abnormal effect
will occur so long as the controlling member is
heldin the position that causes the machine to
run, but when that member is shifted to its 'stop—
ping position, as by releasing a clutch-controlling
treadle, it places. the controllable means :in a

In Fig. 11a hand points the direction in which
the work is fed by an eyeleting machine of the
type hereinafterdescribed. ,An edge-gage i2 is
arranged :to guide the lacing edge E3 of a quarter

55 a spring-‘loaded presser foot I'E (Figs. 1 and 5). A
broad strap I‘! attached to the top of the quarters
by stitches projects from the edge l3 to be
wrapped around the wearer’s shin and secured to
the other quarter by buckles (not shown) _
the strap I1 is folded as represented in Fig. 11, its
leading edge l8 may approach the eyelet-inserting
locality of an eyeleting machine ‘without fouling
the presser foot or some other element of the
machine that would otherwise obstruct its prog

The lever 33 rocks on a fulcrum pin 39 and is
provided with an arm 48 to be engaged and ar
rested by a stop 4| under control of the operator.
As shown in Fig. 9, the stop 4| is connected to a
treadle 42 which has various functions all de
scribed at a later stage.
The feeding component of the finger 2| is de
rived from a rotary cam 43 (Figs. 2 and 3) strad

table l5, but the effective portion is above that
block 61 arranged to slide in a slot 68 in the

ance for the ?nger. As each clenched eyelet ex
cept the?nal eyelet of a run is left unobstructed
by the punch 24 and the spindle 25 (both of which
are retracted immediately after the conclusion of
the clenching stage), the tip of the ?nger enters
the eyelet while rising from a position below the
work, but if the eyelet at the setting locality is
the ?nal or only eyelet of a run, the'tip of the
?nger will be prevented from rising high enough
to enter it. In that event the tip of the ?nger
will approach its ?nal position (Fig. '7 ) with travel
along a straight line 26 without engaging the
work at all.‘
The butt end of the ?nger 2| is a?ixed to a rod.
