- Description
- This object was collected by Brooklyn high school teacher and historian of mathematics L. Leland Locke. A steel shaft holds steel and brass discs six centimeters in diameter. Some discs hold pins and have partially toothed edges. Others are thinner, and may go only part way around. These discs also have a toothed edge and may have a protrusion like those on pinwheel calculating machines.
