Referring more particularly to the drawings,
25 the numeral l designates the heel plate attaching
press provided with the reciprocating head or
ram 2, to the construction of which the present
invention is particularly directed. Generally, the
press is'of the same construction as that set forth
30 in our above referred to application Serial No.
31,478, of which the present application is a con
tinuation in part. As shown in Figs. 1 and 2 of
the drawings, the press comprises a frame 3 upon
which is mounted an anvil 4 adapted to receive a
last 5 carrying a shoe, as indicated at 6. The
upper portion of the frame carries a cylinder 1 in
which is disposed a spring supported piston, not
shown, having a depending rod 8, to the lower
end of which is attached the head or ram 2.
40 Compressed air, or other actuating ?uid, is ad
mitted into the upper end of the cylinder by way
of a valve regulated pipe line 9, so that the pis
ton therein may be forced downwardly, against
the rod 8 and the walls of the socket it in order
to hold the ram in connection with the piston rod.
In addition, a set screw I8 is employed in a cor
responding capacity.
The upper member ill ter
minates in a depending shank extension it which
is substantially U-shaped in cross section, as
shown in Fig. 5. The lower surface of the shank
extension i9 is provided with a pair of relatively
spaced vertical slots 20 which are adapted to re
ceive the ears E3 of a heel attaching plate l0. 10
Such a plate is detachablyconnected and carried
by the bottom surface of the extension i9 by pro~
viding the latter with spring pressed balls 2!,
which engage with the apertures or weakened
areas of the ears i3 to frictionally hold the fas 15
tening plates in connection with the upper mem
ber atthe time of insertion of said plates into the
driving head or ram of the machine. The lower
surface of the shank it conforms with the slightly
cupped or dished configuration of the body of the 20
plate It! and is of the same general plan dimen
sions as said plate, the forward lower portion of
the shank 99 being provided with a shoulder as
ably mounted on the shank extension i9 between
the shoulder 22 and the upper portion of the body
of the member 04. In this instance, the lower
member in horizontal cross section partakes of
the U-shaped form of that of the shank l9 so 30
that a plate i9 may be inserted into its applied
position on the lower end of the shank through
the open front of the lower member. As shown
in Figs. 4 and 5, the lower member is provided
with a transversely extending bar 23 held in 35
place by a bolt or screw 2t, the bar 25 engaging
The lower member E5 of the head or ram is slid

In the operation of the press, a plate It is

cars 13 thereof in the slots 2B of the shank it,
prongs l2, which extend downwardly from the
plate below the edges of the flange II when said
plate is positioned in the press. Also, the plate is
provided with a pair of upwardly extending,
the ears being engaged by the spring pressed balls 60

dropping. By the inclusion of the springs 21, the
lower member of the pressing head will be posi

In Fig. 9, a slightly modi?ed form of head has
been set forth, wherein the head. indicated at 35,
is mounted for swinging movement about a hori
zontal pivot 36 and secured in connection with
the lower end of the piston rod 8. The head is
formed to present a pair of members 31 and 38
located approximately 90‘ degrees apart. The
member 31 is provided with spurs or tines 28a,
while the member 38 is socketed for the reception
of a heel plate I0. In this form of the invention,
40 the member 31 is operated so that its spurs or
tines will penetrate the leather of the shoe soles
and after ‘which the head is revolved so that the
