Details of Gear and Lever Components
Component sketches related to the preceding windmill sheet
The sheet carries small component sketches: an upper study of a shaft carrying a wheel or pulley with a toothed rack, and a bent lever-arm below. The e-Leo caption identifies these as probable details for devices analogous to those on the preceding sheet. No inscriptions accompany the drawings.

Shaft with toothed rack and wheel
The upper drawing shows a horizontal shaft carrying a hub or pulley engaged with a toothed rack. It appears to belong to the same class of gearing as the windmill mechanism drawn on the previous leaf.
Bent lever-arm
Below the shaft is a hinged or bent arm, sketched as an isolated component. It reads as a lever or linkage forming part of the same assembly.
