    Description
    This drawing shows an instrument designed by Robert Hooke for making an accurate hand of a clock. The instrument is made by connecting at specified angles several stiff steel wires which attach to a precise clock dial. The mechanical principle behind this device, Hooke states, could also be used for equations of time, resolving triangles, raising water, facilitating wheel-work, and several other mechanical uses.

    This image is copied from RBO/3/181. The original drawing by Hooke is at Cl.P/20/31/002.
    Object history
    At the meeting of the Royal Society on 21 March 1667, ‘Mr. Hooke brought in the description of a very easy and simple but universal instrument to describe all the kinds of plane dials, together with a demonstration of the principles and reason of it: which was ordered to be registered’ (Birch 2:158). The text and references to the figure are printed at Birch 2:158-60.
