Hoisting apparatus with a great toothed wheel
A machine for raising a heavy weight, with a large geometrically laid-out wheel
The sheet is dominated by a very large circle constructed with an inscribed triangle and rimmed with sawtooth teeth, like the head wheel of a great hoisting engine, with a smaller toothed wheel drawn at upper right. At the left a framed winch with a pulley carries a cord up to the wheel. A central note calls it a 'manner of water,' while a caption on the left explains that this is the way to raise a weight as high as one wishes and that the head wheel must be of a certain form. The reverse is blank.

Winch and toothed head-wheel for hoisting
The caption on the left describes an apparatus for raising a weight up as high as one might wish, and begins to specify how the 'head wheel' must be built. The large toothed circle and the small framed winch with its pulley at the left form the working parts of the lifting engine.
"Manner of water"
A short note set at the centre labels the device a 'manner of water,' suggesting the great toothed wheel and hoist were intended to raise or work with water. The geometric construction of the wheel with its inscribed triangle governs the layout of the rim.
