 Coggeshall slide rule

The Coggeshall slide rule is a specialized type of slide rule designed for performing various calculations in the field of engineering and science. It was invented by William Coggeshall in the early 20th century and is notable for its ability to facilitate calculations related to topics such as hydraulics, structural engineering, and other applications requiring precise mathematical computations. The device typically features a linear sliding mechanism that allows users to perform multiplication, division, and other mathematical functions by aligning scales on the rule.
