TIM Calculating Machine Component


This object was collected by Brooklyn high school teacher and historian of mathematics L. Leland Locke and held by the Museums of the Peaceful Arts in New York City before coming to the Smithsonian. The black and silver-colored metal component consists of eight number wheels on a frame. Each wheel is moved by moving a lever and spring mechanism. Underneath seven of the wheels is a metal cylinder, with all cylinders protruding from a common shaft.
