Dietzgen Instruction Manual for Maniphase Slide Rule

Description:

The citation information for this sixteen-page booklet is: Self-teaching Instruction Manual: Maniphase Slide Rule (Chicago: Eugene Dietzgen Co., n.d.). The slide rule depicted inside the manual is Dietzgen's "National," model 1767, and the manual was received with 1988.0367.01. Detailed instructions are provided for reading the scales, multiplication, placing the decimal point, division, proportion, squares and square roots, cube and cube roots, trigonometry, and logarithms. "Maniphase" on the cover refers to an arrangement of scales in which the company added K and CI scales to Mannheim rules; the word is printed on several slide rules sold by the Eugene Dietzgen Company. Indeed, the manual indicates portions of it could be used with other Dietzgen slide rules, such as model 1772A.
