Lightning Adding Machine


This small seven-wheeled stylus-operated non-printing adding machine has a metal case painted green and covered with felt on the back. It sits in a brown bakelite stand. A stylus fits in the ten holes in each wheel. Placing the stylus in the proper hole and and rotating it enters a digit. The sum appears in seven windows above the holes. The two rightmost and the two leftmost wheels are brass. The three middle ones are steel. The device has no zeroing mechanism and the stylus is missing.

The instrument is marked on the front: THE (/) Lightning (/) ADDING (/) MACHINE (/) CO. (/) LOS ANGELES (/) CALIF. U.S.A.. It is marked with intertwined letters on the back of the stand: GIM.

This machine is from the calculating machine collection of Myron R. Smith.
