Title | Diagram, engine for grinding hyperbolic glasses by Christopher Wren |
Date | [1669] |
Description | Drawing of Christopher Wren's 'engine' for grinding hyperbolic glasses. This follows on from Wren's publication in Philosophical Transactions of the Royal Society, vol. 4, no. 48 (1669), which shows that a section through the axis of a cylinder was a hyperbolic surface, which could then be applied to create a machine to grind hyperbolic lenses. This drawing, however, is not much more than a geometric diagram with shading, and does not take into account the wheels, cogs and other arrangements necessary to translate this into an actual machine.
Includes 2 cylinder with a hyperbolic surface and a disk.
Parts are lettered.
