10 Back transfer with one hand

The Brunsviga 13 RM also possesses back-transfer equipment by means of which resuits can be transferred back to the setting mechanism. For this purpose the setting mechanism is cancelled out, the retransfer lever (front right on carriage) is shifted upwards 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 calculation.

11 Decimal point slide bar and reading of value

All three registers of the Brunsviga 13 RM are equipped with decimal point rails, on to which are attached decimal point indicators. These can be pushed to any required position in order 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 values and cancellation.

The procedure of the most important calculating work is briefly shown in the following practical numerical examples.
