TIM III Calculating Machine

Description:

This sturdy German stepped drum, manually operated non-printing calculating machine has a brass and iron case painted black. The eight-digit entry levers are linked to dials that record the number entered and to steel stepped drums. Levers in front of the dials zero the entry. The addition & multiplication / subtraction & division lever is on the left, and the operating crank is on the right. The plate at the front is easily removed to show the levers and bell.

In back of the levers is the carriage, with nine revolution register dials and 16 result register dials. The zeroing bars for these registers are on the right of the carriage. A knob for lifting the carriage is on its far left. When the entry in the result register becomes negative (as in subtraction or division), a bell rings. It rings again if a number is added to bring the total to zero or more. The entire machine has a steel cover painted black.

A metal tag attached to the front of the machine reads: Sold by (/) The TIMES-INTO Co. (/) TRADE MARK. It also reads: Ludwig Spitz & Co. G.m.b.H. (/) T I M (/) TIME IS MONEY (/) TRADE MARK. It also reads: CHICAGO (/) U.S.A. The front of the machine reads: Made in Germany. Also stamped on the machine is: PATENT. A mark on the machine under the carriage at the right reads: 06573. Another mark on the machine, under the carriage at the left reads: 9239.

The machine was put into use at the Public Service Corporation of New Jersey (later the Public Service Electric and Gas Company) in 1923. The company considered scrapping the machine in 1962, but gave it to the Smithsonian Institution instead.
