Geometric Model by A. Harry Wheeler, Equilateral Triangle Transformable into Square, Plane Dissection

National Museum of American History

Object Details

Wheeler, Albert Harry
Description
The four plastic pieces fit in metal container with cloth-lined lid. The pieces may be arranged as a square or an equilateral triangle. Compare MA.304723.764, MA.304723.819, MA.304723.766, and MA.304723.823. This small version of the model has no hinges.
This is similar but not identical to Wheeler's Model 4ST. Two drawings for that puzzle, both dated January 17, 1932 and April 26, 1932, are in 1979.3002.43, folder 1. The drawings refer to the Mathematical Gazette - no volume or page is given. A drawing in 1979.3002.53 dated January 5, 1932 refers to this model as 4C.
