'2 Claims.
This invention relates to means for feeding
washers to the pins of molds employed in the
manufacture of rubber heels, and it consists in
the constructions, arrangements, and combina
5 tions herein described and claimed.
It is an object of the invention to provide a
washer feeding device of simplicity in construc
tion and operation and one in which the washers
are fed to the pins of a mold regardless of the
1.0 varying height of the pins as well as varying
inclinations which the pins may have.
It is a still further object of the invention to
provide a washer feeding device in which a
washer magazine is provided, and in which the
15 washers are individually placed in position upon
the pins.
Additional objects, advantages and features
of invention will be apparent from the following
description considered in conjunction with the
20
accompanying drawing, wherein
Figure 1 is a vertical sectional view through
the washer feeding device.
Figure 2 is a fragmentary sectional view of the
device in use.
25
Figure 3 is a fragmentary plan view of a series
of molds indicating the positions of the pins.
Figure 4 is a front elevation of the magazine
and feed guide.
Figure 5 is a rear elevation thereof.
30
Figure 6 is a bottom plan view of the guide.
There is illustrated in Figures 1 and 2, a tool
generally indicated at I0, comprising an angu
(Cl. 18--1)
by a slot 24, permitting passage of the upper ends
of pins 25 and preferably the ledge 23 is of a
height permitting the pins to project thereabove
so as to engage the apertures of the washers when
drawn thereacross.
The guide I2 comprises an entrance opening
21 at its rear face, tapering in the direction of
the bifurcation 24 serving to guide the pins so as
to align the upper ends of the pins with the
apertures of the washers. The front end of the 10
guide I2 has a transversely extended slot 28 of
a diameter to permit passage of the washers
therethrough and the-upper edge of the slot may
be recessed as at 29 to permit passage of the
upper ends of the pins therethrough.
15
In use, with the pins 25 arranged within the
heel molds indicated at 3B in Figure 3, the device
is grasped by the handle I 4, the guide I2 being
aligned with the rows of pins 25 so as to admit
the pins through the entrance opening 21. The
device will be held in the position shown in Fig
ure 2, and obviously, the upper end of the pins
will be guided by the bifurcation 24 so as to en
counter the aperture of the lowermost washer
within the magazine 2|.
The contact between
the pins and washers will be more or less ab 25
rupt to effect withdrawal of the washers, but
shock or unsteadying effect will not be imparted
to the operator due to the resilient hand-grip
mounting.
While we have shown and described a preferred
form of the invention, this is by way of illustra
larly disposedhandle II, the lower end of which
tion only, and we consider as our own, all such
mounts a guide block I2. Upon the underside
35 of the handle II there is screw-threadedly en
modi?cations in structure as fairly fall within
the scope of the appended claims.
gaged a shank I3, extending substantially at
right angles to the handle, and upon the shank
there is revoluble a hand grip I4. In' order that
the hand grip I4 may be free of vibrations and
have the necessary ?exibility, the grip has an
axial bore I5 within which a piston I6 is recip
rocable, the latter being secured to the shank
I3 adjacent its lower end. A helical spring I‘!
is interposed between the piston and a washer
'45
I8 seated upon the base of the bore. From the
foregoing, it will be seen that the hand grip
is resiliently mounted and free from undue vibra
tions or shocks which might be imparted due to
encountering pins of the molds, as will be more
50 clearly apparent as the description proceeds.
The guide I2 has an aperture I9 extended ver
tically therefrom and ?xed securely therein,
there is a tubular sleeve 20, adapted to receive
a tubular magazine sleeve 2|. The sleeve 2| is
55 open at its upper end to receive washers 22 ar
We claim:—

1. A washer feeding device for pins of molds
comprising a body member having a pin entrance
slot extending longitudinally thereof and opening
upon the bottom wall thereof, said body having 40
a vertically extended opening, a ledge on the
body member beneath the opening, said ledge
having a furcation extended in the direction of
the slot and opening thereupon,‘ a sleeve ?xed in
the vertical bore, a washer magazine engaged 45
within the sleeve for discharge of washers upon
the ledge, the sides of the entrance slot of the
guide tapering in the direction of the ledge, a
handle on the body member extending rear
wardly of the entrance slot, the handle having a 50
downwardly extending spindle, and a resiliently
mounted hand grip on the spindle.
2. The structure of claim 1 in which the hand
grip includes a bore, a piston ?xed to the spindle
adjacent the free end and reciprocable therein,
ranged in superposed relation, as may be seen in
and a helical spring on the spindle interposed
Figure 2, retained in such position by engagement
between the piston and the base of the bore.
of the lowermost washer upon a ledge 23. As
may be seen in Figure 6, the ledge is bifurcated
