TIM, 1907, Stepped Drum

A stepped-drum calculating machine in a black enamelled case, gilt lettering on the front of the case reading "Tim", sliding setting levers in a curved slot plate across the top, a wide carriage with two rows of white numerals on black drums, every drum showing the single digit 0, a crank with a black wooden grip at the right, every other surface plain black enamel and polished brass, standing on a dark baize-covered table before a deep neutral background, a single raking light from the left catching the gilt letters and the white numerals.

What it was used for
A stepped-drum four-function machine by Ludwig Spitz & Co. GmbH of Berlin-Tempelhof, sold under the trademark "TIM Time is Money". The Smithsonian describes eight zinc-alloy stepped drums, a result register of 16 windows and a revolution counter of nine. It was used in large administrations: the Museumsstiftung Post und Telekommunikation holds a full-keyboard TIM which it catalogues under the keywords Deutsche Reichspost and Postscheckamt (postal cheque office) - 450 mm wide, 14.08 kg. London's Science Museum has a TIM that came from the Prudential Assurance Company, that is from an insurance office.
What was new
Not the stepped drum, which was over two hundred years old. What the TIM could do was carry a 16-place result register in an office machine of which examples survive from postal and insurance ownership. The Smithsonian states that the TIM was introduced in 1907 and first sold in a cast-iron housing in 1909; its own example was taken from a wooden case. Whether Spitz was ahead of the Glashütte works with a full-keyboard stepped-drum machine is not stated by any source checked here; the Museumsstiftung dates its own full-keyboard TIM only to roughly the 1920s to 1940.

Connections

Every connection names its kind. “Forerunner” on its own would be a claim.

  1. Follows fromThomas Arithmomètre1851The Heinz Nixdorf MuseumsForum describes the TIM, built by L. Spitz & Co. of Berlin from 1907, as a stepped-drum machine "of the kind of the machine of Thomas de Colmar". Versions with two counters were sold by the firm as the "Unitas".Source: Heinz Nixdorf MuseumsForum, museum-digital: TIM (Time Is Money)
