Calculating Machine Component
notes: label: Description
content: 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. It consists of eleven circular or partially circular brass parts, attached along a shaft to form a cutaway cylinder. There are protrusions at two points along each part. This may be the backbone of a pinwheel calculating machine, without the pinwheels.
