\ This invention relates to an improved washer
placing machine, and more particularly to a ma
chine of this kind‘which‘is adapted for use in
Vplacing nailing washers on the pins of lrubber
heel producing molds.
fAn object of the invention is to provide an im
proved Washer- placing machine having novel
washer feedingmeans including a main finger
washers are »automatically placed on the pins by
the fingers.
Another object of the invention is to provide
a Washer placing machine having a novel ar
r rangement of washer feeding fingers including a
pair of fingers adapted for relative lateral swing
ing movement and interconnected by propor
tional movement mechanism.
1 A further object of the invention is to provide
an improved washer placing machine having a
frame with a member thereon movable about
pivot means extending transversely to the longi
tudinal axis, and wherein washer feeding fingers'
, >carried by such pivoted member are adapted for
l The frame I0 may be provided with a substan
tially flat bottom plate which, in general appear
ance and outline, may correspond roughly with
the sole of a shoe or the bottom plate of a plane.
The heel‘end of the frame, which is also the for
ward or leading end, may be constructed with a
hollow part I5 which houses certain ñnger carry
ing mechanism to Ybe described hereinafter and
provides a connection for an operating‘handle I6.
It will be understood, of course, that the bottom
plate may be formed integral with the frame I0,
or for convenience of manufacture, may, as shown
in this instance, be formed by plate sections I'I
and I8 which are connected to the bottom of the

More detailed reference will now be made to
the accompanying drawings ‘wherein lí> have
vshown one embodiment of Vmy improved washer
55 placing machine. It will be understood, of course,
Frame por
For operably mounting the fingers II and I2 I
may provide a finger carrier which is in the form
of aK movable member 22. As shown in Figs.V 1
and 2 the member 22 maybe a frame-like part
which is disposed in the hollow body part I5 and
which is mounted for vertical rocking movement 40
by pivot means extending transversely with re
spect to the longitudinal axis of the machine.
The pivot means may be in the form of screws 23
extending throughthe sides of the frame I0 and
having pin projections 24 upon which the member
22 is fulcrumed.
The member 22 may be constructed to include
a ,transversely extending bar portion 25 into
which the pin projections 244 extend, and may
also, include spaced arms 26 *whichl extend for- .
wardly from the bar portion 25 towards an open
ing 2‘l ln the end wall of the hollow frame part
I5. The arms 26 may be connected by another
bar portion >28 which extends transversely of the
`machine just inside of the opening 21. ` From the 55
that the machine shown in the drawings is by way
arrangement just described it will be seenY that
of example only and that the invention maybe
the member 2.2 is pivoted on the frame I0 for
embodied in various other machines andappa
