2013.3.74Description
These model machines are designed to illustrate the mechanical principles of the lever, the wheel and axle, the pulley, etc. The taller frame equipped with the pulleys was provided with horizontal strings spaced an inch apart. These strings were attached to marked scales to the right and left. Since this photograph was made the scales and strings have been replaced.
Considerable space in the textbooks of natural philosophy of a century ago was devoted to the explanation of these simple machine principles.Collection
