toward its position as shown in Fig. 8. During
this movement of bell crank 353, the lower arm
355 thereof engages a pin 362 projecting from
plate 325 and so elevates the latter backto the
position of Fig. 7. In the course of this action,
arm 322 of bell crank 323 engages lug 32| of trip
lever 3| 1, and is caused thereby to lswing relatively
to plate 325 to the position shown in Fig. 7. On
the return or upstroke of gear segment 16, bell
crank 353 is then rocked back to the `position of
Fig. 7, its hook member 351 clearing pin 321 car
ried by bell crank 323 since said pin is now at the
right hand end of its slot 326, it being understood
that the bell crank 323 is now again held in the
position of Fig. 7 by trip lever 3 I1.
Thus, assuming bar 216 to have been shifted
to position with one voiî its notches 296, 29|, etc.,
to a. position of register with the corresponding
moved through their return stroke by the cams.
It will be evident that the number of energize
tions of motor M necessary to cause each such
described actuation of the price counters depends
upon the -rate of angular rotation imparted to the
20 particular cam corresponding to the particular
pawl arm 268, which has been released by regis»
tration therewith of a notch in bar 216. And the
rates of angular rotation imparted to the differ
ent cams being all diñerent, it will thus be evi
25 dent that the price registered on the counters will
be governed by which of the notches 230, 23|, 292,
and 233 in the Ibar 216 has been registered with a
pawl arm 266.`
In accordance with the invention, the bar 216
