Apparatus designed by Joseph Priestley for the generation and storage of electricity, from an engraving by Andrew Bell for the first edition of Encyclopædia Britannica (1768–71)
By means of a wheel connected by string to a pulley, the machine rotated a glass globe against a “rubber,” which consisted of a hollow piece of copper filled with horsehair. The resultant charge of static electricity, accumulating on the surface of the globe, was collected by a cluster of wires (m) and conducted by brass wire or rod (l) to a “prime conductor” (k), a hollow vessel made of polished copper. Metallic rods could be inserted into holes in the conductor “to convey the fire where-ever it is wanted.”
Basic electric circuit, with switch, battery, and lamp.
