1 Operation of the machine
The Brunsviga 13 RM, your new Calculating Machine,
stands before you. You have just unpacked it, and
now you wish to get to know the machine and how
to operate it as quickly as possible.
The Brunsviga 13 RM is immediately ready for
operation; you can start.
Please place the machine on the right in front of
you in such a manner that you can turn the crank
comfortably and also have a clear view of all the 3
The operating handle is drawn out a little from its
rest, after which you turn the handle a few times
to the right and a few times to the left for pratice,
without, however, letting it go back into the rest after
each turn. All crank rotations should be made quickly
and evenly avoiding sudden jerks. Once you have com-
menced to turn the handle, the revolution must be
completed, i.e. you cannot reverse the direction of
rotation in the middle of a revolution.
2 Setting levers and check register
The number is set by means of the levers in the
setting mechanism. You will see that the setting track
of each of the levers is marked with the numbers 1 -- 9.
If you, therefore, wish to set any number, e.g. «5»
you draw the lever up to the embossed «5». You
will notice that the «5» also appears in the check
register after setting. In the case of multiple digit
values it is of most advantage to put the figures into
the machine starting from the left and beginning with
the first digit, i.e. for instance in the case of the
5-digit number 27354, the 5th lever is first of all
set to «2», (the setting levers are numbered by means
of the digit numbers above the setting control
mechanism), then the 4th lever is set to «7», the 3rd
lever to «3», the 2nd lever to «5» and the 1st lever
to «4». Now as a control, the number «27354» can
be read off from the check register.
Please practice a little with any arbitrary numbers.
