a self-opening microswitch 262 supported on the shelf ‘
102, momentarily closing the microswitch. Closing of
the microswitch energizes the coil of a relay K1 (see
FIG. 23), closing relay contacts KIA and KIB, the
closure of the contacts K1B acting to complete a holding
circuit, so that the microswitch 262 may open immedi
ately after the tip of the arm 261 has moved past it.
Closing of the relay contacts energizes the solenoid 260,
whereupon the solenoid plunger 259 is pulled to the right
of FIG. 14 and, through the spring 258, swings the lever
256 counterclockwise. The roll 257 carried by this lever
then engages the lower end of the connecting rod 196
and moves it upward into a position in which the stud
194 engages the lower end of the T-slot 195 provided
in the rod to render the rod effective to impart inter
mittent movement to the clutch 198 to which it is con
nected at its upper end, so as to rotate the feed wheels
226, 228 to feed rod cement into the melting chamber,
as well as the melting disk 254 and the gear pump 46
to supply molten cement to the nozzle 38 for coating
the successive portions of the tape in timed relation to
the rotation of the work feed rolls 50, 52. The quan
tity of cement fed at each turn of the clutch 198 may
be varied according to speci?c requirements by adjust
ment of the bar 193 relative to the disk 192 so as to
vary the eccentricity of the stud 194 and hence the throw
of the connecting rod 196. When, at the end of an oper
ating cycle, the treadle 112 is released and the arm 98 is
rocked counterclockwise with reference to FIG. 2, the
arm 261, on contacting the microswitch 262, will swing
clockwise about its pivotal connection to the arm 98,

, wise of the machine in contact with the edge faces of
the ribs to cause the ?nger to move with the tape guide
bar 286. For thus moving the block 298 with the ?nger

to an arm 432 which is pivoted at one of its ends for
limited heightwise swinging movement on a stud 434 in
the lower bifurcated end of a block 436 which is ?xed
at its upper end to a bracket 438. The opposite end of the
’ arm 432 is connected to the bracket 438 by a screw 43?
extending through a slot in the bracket. The bracket 438
is secured to the casting 58 which carries the upper feed
roll 50, whereby the wheel 426 can move with the roll 59
toward and away from the insole. A compression spring
mounting the arm 342 is mounted the rear end of an
arm 490 the forward end of which is normally in en

wardly when the wheel 426 rolls in contact with a thicker
portion of the insole, downward pivotal movement of the
arm being limited by engagement of the head of the screw
439 with the bracket 438. The friction of the wheel 426
is adjustable by means of a compression spring 445
mounted on the shaft 428 and bearing against one end
of a bushing 446 loose on the shaft, the other end of the. 55
bushing bearing against the outer face of the wheel
426. The compression of the spring 445 is adjustable by
means of locknuts 447, 448 threaded on the outer end
of the shaft 428. Further, by loosening the screw 431,
the block 430 may be turned a few degrees to vary the
angle of the wheel 426 with relation to the line of feed of
