Summary

Portable index typewriter of the type-wheel class, manufactured by Wernicke, Edelmann & Co., of Berlin, Germany, and marketed by the Columbia Typewriter Company of New York, U.S.A. Production began in 1897 and ceased in 1910.

The typewriter incorporates a type-wheel with three rows of characters held above a cylindrical platen. A pivoted handle is moved around a curved index, marked with letters, numbers and other characters, until the desired character is reached. Movement of the handle also rotates the type-wheel to bring the selected character to the printing point. Pressing the handle down presses the type-wheel down on to the paper and platen. As the type-wheel descends it brushes against an inking roller. Three keys to the left of the index mechanism provide shift and spacing functions.
