and during the machine cycle, the hooked arm 62 en
gages over the stud 61 to prevent movement of the slide

the ?rst 20° of rotation of the mainshaft 73, is moved
clockwise during approximately the next 90° of rotation
to block movement of the arm and the operation of the
toration of the release shaft 63 counter-clockwise beyond
its normal position at the close of a machine cycle
causes a cam surface of the hooked member 62 to move
the slide 57 upwardly, against its spring tension, thereby
removing the surface 687 from the stud 54 of any de
pressed key, which latter restores upwardly in well
known manner.
A zero stop control slide 64 is also provided in each
keyframe 53 and has a cam surface 65 in the path of
movement of each stud 54, the slide 64 also being slid~
ably mounted on the studs 58. Projecting laterally from‘
the lower end of the slide or detent 64 is a stud 66 which
lies in the path of counter-clockwise rocking movement
of an associated zero stop pawl 67 pivotally mounted on
a stud 68 secured in the keyframe 53. The Zero stop
operation the universal rod 87 remains stationary during
to effect its operating stroke, dwells in fully operated
position for 75°, and is then returned to normal position
during the next 90°, so that normal position is reached at
275° of rotation of the mainshaft 73‘. The slot 86 is nor
mally so positioned that it is concentric to and partially
encompasses the universal rod 87‘, and the lower bound
ing wall 88 of theslot is curved to provide a camming
surface, as will be described.
During additive entries, after the latch 74 has rotated
clockwise to position its surface 83 beneath the nose 84
of the locking plate 78, the universal rod 87 commences
its clockwise movement about the mainshaft 73'to drive
the differential arm 72 through its eccentric engagement
within the slot 86, the nose 84 of the locking plate 78

Freely mounted on a rod 1112 (FIG. 2) extending be
tween the machine side frames is a plurality of rockable
plates 103, one associated with each amount differential
mechanism, each supporting a wide coupling pinion m4
key. When the latter occurs, through the continued
motion of the differential arm 72 (FIG. 2), the latch 74
is rocked counter-clockwise, removing the surface 33
from beneath the nose '84 of the locking plate 78, and
presenting a rectangular depression 90 thereto, and fur

by the stud 199 as shown in FIG. 5, thereby positively
to retain the lever 202 in its counter-clockwise position
during ‘approximately the ?rst 110° of rotation of the
mainshaft 73 (-FIG. 7), after which the gradual restora
tion of the lever 2.02 is permitted by the movement of
the vlink ‘187 to the right causing the restoration of the
shaft 185 to its normal position. Counter-clockwise ro

of the arm 208 to the position shown in FIG. 5, wherein
the nose of the by-pass pawl 2119 and the cam surface
214 are both moved into the arc of the transfer studs
154 on the item totalizer wheel 1111.
As will be appreciated, a stud 154 will be located in
a position representing zero, or an amount, depending
on the setting of the item totalizer wheel 161.
In the assumption that an amount stands on the item
totalizer wheel 101 then, when the differential arm 72
moves counter-clockwise the by-pass pawl 209 first by
passes the stud 154 and then the cam surface 2114 en

clockwise. Upon this counterclockwise movement of the
arm 208, its right-hand end, in cooperation with the stud
213, trips the latch 74 clockwise to the position shown
in FIG. 6, thereby permitting the locking plate 78 to re
