Apparatus developed by James Prescott Joule (1818-89) for determining the mechanical equivalent of heat. A container with water, oil or mercury contains blades attached to a spindle. A rope attached to a drum is wound around the spindle. A weight falling against the scale rotates the blades. Raising and lowering the weights increases the temperature of the liquid. The energy consumed can be calculated from the rise in temperature and the distance travelled, Historic, digitally restored reproduction of a 19th century model, Record date not stated
