plates I6 mounted in bails i9 rockable on shaft
I9 secured in carriage plates ll, 8. One of the
bails i8 supporting each set of plates I@ is con
nected by a link 29 to the respective setting lever
rail 29. By turning the hand wheel 44 clock
wise (as viewed in Figure 5A) the carriage 9 is
shifted to the right.
The carriage shift is utilised to multiply the
set-up values by decimal multiples, i. e. by 10,
100, 1000, and so forth when shifted to the left,
or by 0.1, 0.01, and so forth when shifted to the
right. This arrangement of the set-up mech

capacity up to 99, 999, 999.9999 for the multi

are arranged in three banks clearly shown in
Figure 6.
The middle bank comprises LIBZ, S,
The lower bank comprises Ll04,
L10, and Dl selector plates l5 mounted in balls

23 to respective levers 5. Selector plates I6 co

for horizontal movement opposite the respective
banks of selector plates. By aligning the setting

brought into working position opposite the sens

the value 03d., or 0.03d., or 0.003d., or 0.0003d.,
as the case may be, will be entered into the reg

Those sensing pins 24 which are not aligned
with any selector plate lâ (i. e., the Dill-2 pin
when the plate Dl (3) is in the +7 position) are
rendered inoperative by means which will be
described in due course.
‘
Considering now the selector plate L|0(I), in
the initial position 0 only one notch designated
“1,” which is one step deep, is aligned with a sens
ing pin, namely that of the LIB denomination.
Consequently, the amount £10 will be registered.
When this plate is shifted to the left, this same
notch “l” will be aligned with pins 24 of the
higher pounds denominations LN2-M08; thus
Figure 2 (for shillings), and Figure 3 (for
pounds). Columns -2, _3, -4 in Figure l are
left blank as the numerical values of the respec
tive decimal multiples are identical with those
of column _1, the decimal point being shifted in
each successive column one step to the left. It
will be understood that although all values shown
in Figures 1-3 are represented by notched selector
plates I6, the total number of notches in plates
I6 is considerably less than the number of digits
contained in Figures 1-3, since one and the same
notch may represent a digit of several denomina
tions of a decimal set of units. Thus, a single
notch designated “4” on plate M040!) in Figure
9 may represent, according to the position of the
carriage, £40,000 or £4,000 or £4, and so forth.
Selector plates I6 of the upper, centre, and

As already described, the notched selector
plates iB determine the amount of movement of
sensing pins 24 during the working cycle of the
machine. As shown in Figures 6, 6A, sensing
pins 24 co-act with three-pronged feelers 41 piv
oted at 48 in gear sectors 49 rockable on a shaft
5D fixed in the supporting structure 2, 3 (see also
Figures 7, 7A). Each gear sector 49 co-operates
with a numeral wheel of the result register as

Prongs 68, 69, 10 on feelers 41 are so shaped
