This key can also be pressed in, so that the carriage
is then released. It can then be moved by any number
of positions.

10 Back transfer with one hand

The Brunsviga 13 RM also possesses bac k-t rans fer
equipment by means of which resuits'can be trans-
ferred back to the setting mechanism. For this pur-
pose 'the setting m e€e h a n i s m is cancelled out, the
retransfer lever (~front right on carriage) is shifted
upwa rds and then the product register is cancelled
out. The value from the product register is now
automatically set in the setting mechanism, ready to
use for the next calcvlation.

~1 Decimal point slide bar and
    reading of value

All three registers of the Brunsviga 13 RM are equipp-
ed with decimal point rails, on to which are attached
decimal point indicators. These can be pushed to any
req u i red position in o rde r to facilitate the reading
off of the value.

Calculating the 4 basic kinds
of calculation

Calculating the 4 basic kinds of calculation on the
Brunsviga calculating machine is done as variations
of digit setting, carriage tabulation, operating handle
rotation, reading of valuesand cancellation.
The procedure of the most important calculating work
is briefly shown in the following practical numerical
examples.
