Sector and joynt rule
A sector is an instrument for solving computations which use the rules of proportion. This wooden sector and joynt rule was made around 1686, and was possibly owned by Robert Hudson of Leeds.
The sector and joynt rule has a brass hinge and brass reinforcing studs. This side in inscribed with various scales is signed 'Robert Hudson Leeds 1686'. On the inner limb edges are foot and inch scales, on the outer ones trigonometric scales.
Although London was the centre of the British instrument trade, instruments were made and used outside the metropolis from a fairly early date.
