Description
Adding machine - 'The Calcumeter' and box.
Calcumeters were invented at the beginning of the 20th century, and were made until the 1920's.

This example has eight dials.

1981.488.1 - Solid stainless steel flat calculator with a row of dials on the top. There are 5 rotary dials starting from the left followed by one large one. On the right there is a medium sized dial and then a small one.
The 5 on the left are all marked from 1~9 in an anti-clockwise manner. The large one is marked from 1~19 in an anti-clockwise manner. Then the medium one is marked from 1~11 anti-clockwise followed by finally the smallest one on the extreme right marked 1~3 also anti-clockwise.
Each of these has an inner brass disc with concentric notches in it. It is interesting to note that these discs move only in the clockwise direction. This calculator has been patented in Great Britain but made in the United States of America.
