Manuals & Documentation

An image of various slide rules from the collection of the Division of Medicine and Science at the National Museum of American History.

Keuffel & Esser, Pickett, Dietzgen, and other major slide rule companies often included an instruction manual in the purchase of the instrument. Some donors have provided these booklets and other paper items, such as advertising flyers, directions for cleaning slide rules, warranty certificates, and even cash register receipts. The Museum of Science & Industry in Chicago previously owned and displayed one of the Thacher cylindrical slide rules, and it arrived with its exhibit label. To see the instruction manuals alongside the objects they explained, please see the index by makers & retailers page.

Instruction Manual for Georgia Iron Works Hydraulic Slide Rule

The citation information for this 20-page stapled booklet is: T. W. Hagler, Jr., GIW Hydraulic Slide Rule Instructions [and] Formulas, rev. ed. (Georgia Iron Works Co., 1969).
Description
The citation information for this 20-page stapled booklet is: T. W. Hagler, Jr., GIW Hydraulic Slide Rule Instructions [and] Formulas, rev. ed. (Georgia Iron Works Co., 1969). Tom Hagler wrote this explanation of the slide rule designed by his brother, Danny, for the pump manufacturing firm owned by their family in Grovetown, Ga. The rule made it easier for the company's engineers to make calculations related to the flow of slurry in pipelines and pumps. See 2009.0100.01. The rule illustrated in this booklet, which has C and D scales, is a later version of the instrument than the example in the collections. The booklet also contains instructions for caring for the rule that presumably came from its maker, Pickett Industries (formerly Pickett & Eckel) of Santa Barbara, Calif.
