Addiator Addfeet Junior. Addiator is a the brand name of Slide Adders (Troncets) made by Carl Kubler in Berlin. The name Addiator tends to be used for all slide adders in the way that Hoover is used for all Vacuum Cleaners. The Frenchman Louis Troncet is considered to be the inventor of the Addiator type Slide Adder in 1889.

Addiator Sizematic.

Fractomator, Feet, Inches and Sixteenths.

Addiator Elsarie. I am reliably informed by an Egyptian friend that the decorations on the surface of this Addiator are Pharaonic in origin. I am confident, therefore that this Addiator was intended for the Egyptian market. The final column is delineated in Eighths, this is still a mystery to me. I have not yet found an Eqyptian system of measurement which uses Eighths.
