Pulsing of the solenoid 110 shifts slide 1133‘ to release
the one revolution clutch 93 and at about the same time,
the closing of the contacts of relay 23% causes solenoid
228 to be energized and retract the holding bail 22-0
from the count wheels Slit, 32 and 34. At the start of rota
tion of the cam shaft 72, the cam 134i moves away from
both of the solenoids 156 ‘and 158‘. When this occurs,
the slides 116 and 118 are thrust by their springs 126 into
holding engagement respectively with the units wheel 30
and the tens wheel 32 to limit rotation thereof to one tooth
rotation for each. This rotates the tens wheel 32 to the
“1” position while the units wheel returns to “0” position
thereby to register “10.” From the ‘above, it will now be
understood that when the units and tens wheel register
