The Adix adding machine was an early mechanical calculator with a click-wheel column adder, nine keys, and an exposed system of gears. The Adix adding machine was invented in 1903.
– Improved versions of the device were manufactured under other names, such as the Diera in 1911 and the Kuli in 1913.– According to the device’s patents, it appears that the Adix’s key selling point was that it was noiseless.
Adix adding machine inventor Josef Benedikt Pallweber was born on February 7th, 1858, in Schörfling am Attersee bei Vöcklabruck, a market town in Upper Austria.
Adding with the Adix adding machine occurred through key depression. Interestingly, the machine did not permit the addition of whole amounts it merely permitted the addition of columns of individual digits.
The Adix adding machine also made history for its reliance on an early version of the keyboard we know and use today. Beyond this, the Adix adding machine was also significant for its small size.
