Otis king is a type of pocket-sized mechanical calculator commonly used for performing mathematical calculations. It is also known by the name "cylindrical slide rule" or "mechanical slide rule." The term "otis king" specifically refers to a brand of this particular type of calculator, named after its inventor, William Otis King.
The otis king consists of a cylindrical metal body that is engraved with numerical scales and various mathematical functions. It typically features a knob or a slide that can be rotated or moved along the body to perform calculations. The scales on the otis king usually include logarithmic scales, trigonometric functions, multiplication and division scales, and other mathematical formulae that allow for complex computations.
To use an Otis King, a person would set the scales and sliders on the device according to the values of the numbers involved in a calculation. By aligning the appropriate values on the scales, the user can perform addition, subtraction, multiplication, division, and even more advanced mathematical operations. The device is manually operated, allowing users to control and manipulate the instrument to find specific solutions.
Otis kings were popular in the early to mid-20th century, particularly before electronic calculators became widespread. They offered a portable and efficient means of performing calculations in various settings, from offices to workshops to scientific laboratories. However, with the advancement of digital technology, the use of the Otis king has significantly diminished. Today, it is primarily a collector's item or a curiosity of historical significance, with more sophisticated and accurate calculation methods available.
