Edward Staite's patent electric light apparatus, exhibited at the Hanover Square Rooms, London. The light used a weight-driven mechanism, controlled by the heat of the arc of electricity expanding and contracting a copper strip. Although not a commercial success to begin with, W. Petrie's improvements to the original design led to Edison and Swan adopting the light in the 1870's.
