The operation of the device illustrated in FIGS. ‘1-7 is
as follows:
.
When the timing device is not operating the knob 11 is
at the “Off” position as shown in FIG. 1. The limit switch
31 is open (FIG. 7) and neither motor is running.
Whenever the knob 11 is manually turned in clockwise
direction a small distance towards position 1 (MG. 1)
or whenever a pin 53 in the time clock (FIG. 7) causes
the switch 52 to close, both motors 112. and '13 start to
run.
Since both motors are driving through the over
running clutches represented in ‘general by the numeral 7,
the shaft ‘6 will be driven by the motor of the greater
speed, namely the indexing motor .12, while the clutch
driven by the slower timing motor is overrunning. The
shaft 6 will drive the driving arm 16 through bevel gear
9 to which it is ?xed. Ann 16 will drive the arm 17
through drive pin 20, causing the arm ‘17 to rotate, and
additional overruning clutches.

FIGS. 3, 9 and 10 illustrate a modi?cation of the inven
tion wherein this may be accomplished as will now be de~
scribed.

Mounted on the shaft 6a are a multiplicity of over»

gears 55, 56, 57 and 58, the construction of which is iden

of the four drivingmotors 59, 60, 61 and 62. One of
these motors (59) is the indexing motor. It has the high

are timing motors.

vOn its return swing the timing arm 17 reaches a
position where the timing switch 25 is again contacted

to run again. It is obvious that the timing period required
for the timing cam to pass a timing unit depends on the
axial position of the screw 37 “of the timing unit.

Any alteration in the setting of one tim
