cated on the left sidey of the machine with its
. upper surface at approximately the level of the
top of the machine -head I2 and is fastenedf to
the headby bolts I5 (Fig. 8) which pass through
y the support by a counter transfer mechanism
which reverses the movements of the counter
when being placed on the support. The counter
transfer mechanism is operated by the machine
through mechanism which will hereinafter be de
scribed, the machine operation being initiated by
the manual operation of a yclutch lever 214
(Fig. 1).
'
-
The counter transfer mechanism comprises a
pair of levers 5d and 52 (Fig. 3) which are locat ed
- rearwardly of the cement pot counter support
and arev provided with counter gripping means
consisting of a pair of bars 65 and 6B which are

After the counter gripping means takes hold -of
of the pot. Due to the parallel arrangement of

the links 26, 2B, the plate 20 is held in a hori 70 acounter

of the shaft being effected by the action of a
the walls of the counter will be coated without
of a molded counter- and prevent it from tilting l
getting cement on the inturned ilanges.
The shaft 34 extends beyond the inner side ‘
segmental gear 'I6 on an elongated pinion ‘I4 which
is fastened to the rear _end of the shaft 56. When
of the pot It (Fig. 3) where it is connected to 75 the arm 54 is rotated, the link 82 is caused to

rotate with it by the action of a pair of spaced
arms 'i8 and 80 (Fig. 20) which project out from
the blank portion of the pinion 'it and receive
the rear portion of the link between them.
The shaft 56 is mounted in a bearing 60 which
is shorter than the distance between the adjacent
ends of the collar 55 and the pinion 14 (Fig. 3)
so that the shalt 56 can be moved rearwardly in
the bearing >during the early part of the counter =
. transferring operation to move the wider part of
the counter opening at the. front of the counter
opposite the plate 20 as the counter is raised from
the carrier bythe arm 54 and thereby avoid
opening the counter wings an appreciable
amount when thev counter is moved upwardly Y
past the plate.
The teeth on the pinion 14 are
of such length that they will remain in mesh'
with the teeth in the gear segment ‘I6 at all times
during the axial movement of the shaft 56.
The hollow shaft 56 is moved back and forth .
in the bearing 60 by the rod 84 (Figs. 3 and 9)
which 'ls mounted in the hollow shaft and is fric
tionally coupled with the shaft by a spring
tion of its operation. At the beginning :of an
assembling operation, that is, when a counter is
placed on -the cement pot counter carrier, the
arm 54 is positioned a slight distance rearwardly
of the position shown in Fig. 3, and the clamping
levers 50, 52 are spaced wider apart than they
are shown in that ligure. When the counter is
ready to be taken oiï the support, the operator
initiates the ñrst machine operation by moving
the clutch lever 214 to the right, as viewed in
Fig. 1. This causes the rod 84 to move to the
left, as viewed in Fig. 3, carrying the shaft 56
and arm 54 with it until the pinion 14 strikes the
bearing 60 after which continued movement of
the link 82 causes the levers 52 and 50, through
the action of the gears 62,64, to move inwardly
toward each other until the needles ‘l0 grip the
sides of the counter. Axial movement of the rod
84 is then stopped fora moment and the shaft
56 is rotated to release the counter from the .
latch 24 (Fig. 26) and raise the inturned counter >
flanges above the plate 20. . As the counter
pressed bar 86 which is seated in a groove formed
in the rod. The bar is forced against the inner ,
wall of the shaft 55 by a long bowed spring 88
(Fig. 3) which is conñned between the back of
the bar 06 and the bottom ofthe groove formed
in the rod. Thus, when the rod 86 is reciproc
ated, the friction betwen the bar 86 and the ;
inner wall of the shaft 56 will cause the shaft
to move with the rod until either the sleeve '55
or the pinion 74 strikes an end of the bearing
65 whereupon the shaft 56 will stop and the rod
ñanges move above the plate 20, the rod 64 is
moved sharply to the right, as viewed in Fig. 3,
partly to withdraw the counter from the support
while the plate 20 is in the relatively wide mid
section of the counter. During this movement
c-f the rod 84, the shaft A5|i continues to rotate
but at a slower rate and concomitantly raises and
tilts the counter so that the counter assumes an
angular relation with respect to the plate 2li. Aft-er
the counter assumes a desired angular relation
with respect to the plate 20, the rate of the rear
ward movement of the rod 84 is reduced. Con

84 will continue its movement.

the shaft 56' until the counter is seated flange
downward on vthe U-shaped support 58 (Fig. 20).
tional movement of the rocl is utilized to open
and close the counter gripping means. The con
trol of the counter gripping, means is effected
through the link 82 which is connected to the rod
84 by a plate 81 (Figs. 3 and 23) attached to an
arm 85 formed on the rearwardly projecting end
of the rod 84'.
When the counter is seated on the support 58, a
clamping iinger 90 (Figs. 18 and 24) is moved, in
a manner which will hereinafter be described, to
' a position where it clamps the inturned counter
flange against the support 58. As the counter is
clamped against the support 58 by the finger 90,
the arm 54 strikes the bearing 60 stopping the
rearward movement of the shaft 56. The rod
The rod 84 and the pinion 14 are operated by
a cam 92 (Figs. 11 and’lß) mounted on a shaft
94 which is coupled toy the main
the machine by a clutch 96 (Fig.
92 is located outside of the head
the cement pot I4 and controls

l2 adjacent to
the pinion 14
64 continues to move to the right after the arm
5ft stops, thereby causing the link 82 to move
rearwardly relatively to the arm 54 and move
the clamping levers 50, 52 away from each other
through a lever 98 which is connected at its up

his hand, separates the quarter lining from the
upper, and slips the upper over the counter, the

The mechanism for effecting the above opera
tions consists of a cam 280 which is located .'
within the head i2 and is keyed to the driven
shaft 98 (Fig. ll). The heightwise movement
of the form 210 (Figs. 16 and 18) is jointly con
trolled by cam grooves 282, 404 formed, respec
tively, in the opposite side facesof the cam 280.l
the lever is moved in a counterclockwise direc
tion to raise the form. The linkage system con
sists of a link _308 (Figs. 16 and 18) which is
connected at one end to the upper portion of the -
lever 286 and at its other end to the arm 3v|0 of
a cam 3|2 which is mounted on'a transversely
extending rod 322 supported bythe side wallsA
of the head |2. The face of the cam 3|2 engages
a roller 3|4 on a slide bar 3|6 which is urged to
ward the rear of the head I2, or to the right as
viewed in Fig. 18, by a spring 320 which is con
nected'at one end to the bar 3|6 and at its
other end to the rear wall of the head. The rod
322 passes through an elongated slot 324 formed
in the rear portion of the bar 3|6, the slot per
mitting forward or rearward movement of the
bar with respect to the cam as different por
tions of the cam act on the roller 3|4 and cause
the displacement of the bar. The forward end
of the bar 3|6 is connected by a pin 326 to the
upper end of a, supporting arm 328 which is piv
oted on a rod 330. Also pivotally mounted on

336. The portion of the clamping ñnger Sil which
lies opposite to the bar elli is provided with a
caused by the lengthwise pull imparted to it by
the toe and tip-line-grippers.
IAs the form 21D moves up into the upper, the j
lower portion of the lining adjacent the side walls
of the counter is stretched inwardly away from
laterally extending pin 335 which passes through
the side walls, ln a manner which will now be
described, so that the margin of the heel seat

the inturned counter flange. When the operator
smooths the lining against the inner walls of the
counter, the margin of the lining will lie over
the inner ends of a pair of transverse levers 368,
370 (Fig. 21) which are positioned opposite to the
side walls of the counter (Fig. 3). The levers
368, 370 are pivoted, respectively, on pins 372,
the upper shaping form 2li] is raised, the bar 3l6
is moved in a forward direction from its posi
tion shown in Fig. i8'. The initial portion of this
' movement causes the pin 335 to ride upwardly
in the slot 338, thereby lifting the finger 90 from
the counter ñange, and continued movement of
the bar after the pin contacts the rear wall of
‘ the slot carries the linger with it to the position
shown in Fig. 16 where it is clearof the rear wall ~
of the form Zlli.
Located rearwardly of the bar SIB is a latch
36!) which holds the finger @d in its inoperative
position shown in Fig. 16 until the appropriate
time during the counter transfer operation when
a raised portion 356 of the cam 283 moves the
latch to an inoperative position, thereby releas~
ing‘the linger and permitting it to clamp the
counter flange against the counter support. The
latch consists of a forwardly extending arm 354,
which engages the rear end of the bar 3 I6, and a
314 mounted on ears on the top of the head l2
adjacent to the side walls, the outer arms of the
levers projecting beyond the sides of the head
and being urged downwardly by springs 375,
while the inner arms of the levers extend toward
the center of the head and are substantially V-shaped so that they pass beneath the ilange of a
counter on the support 58 (Fig. 20). As the heel
end of the form 2lll is moved into the heel end
of the upper,- a bar 366 (Fig. 18) moves ahead of
the heel end of the form and grips the lining ben
-tween it and the ends of the levers 368, 310, as
shown in Fig. 21. As 'the heel portion of the
