The machine of this invention has a plurality
of denominational rows of amount keys 4!, one of
such denominational rows being illustrated in

In its return movement clockwise, the bail 56 20
picks up the segment 52 and returns said seg

pressed, the‘ zero stop lever retains the rack 41 in
its zero position, as shown in Fig. 1, during ma

In the machine of the present invention, mech

non-repeat mechanism for the machine.
Describing in detail the mechanism outlined
above, the spring 290 (Figs: 3 and 4) normally
