Object Details
- 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.
