Description:

This model comprises three different selectable gears. A truncated cone-shaped lantern gear engages three toothed wheels of different diameters. It is this lantern gear, moved by a crank handle, which transfers motion to the three toothed wheels. These wheels have different speeds according to the time it takes them to complete a full rotation. The simplified device shown in the model could have been applied to several different types of machinery.
