Reuter's Multiplying and Dividing
Machine Manufactured
by Saxonia for Carl H. Reuter (circa
1920) serial number
3139 This machine has eight
places in the setting mechanism, nine places in the
revolution counter, and sixteen places in the result
register. It also features two locking mechanisms: when
activated, the first mechanism prevents the result register
from being lifted until the crank is returned to the neutral
position. The second prevents the user from switching
between addition and subtraction until the crank is returned
to the neutral position. This machine can be tilted
backwards or forwards and locked in its stand, to suit the
user's preference. In place of the sliders
usually found on this type of machine, this early model
featured "small levers, movable in circular
arcs".
