Consul, the Educated Monkey

A mechanical calculator in the form of a monkey, constructed of enameled sheet metal. When each of the monkey’s feet are moved to point at two numbers, the monkey’s hands move to point at the product. A cardboard addition table is included, which when placed over the multiplication table causes the monkey to add the numbers indicated by his feet, rather than multiply. Also included is a cardboard instruction sheet listing the monkeys talents and commenting “It makes no difference whether children are bright or stupid, he never loses patience at having to answer their questions”. The calculator was patented June 27, 1916, by William Robertson, of Belmont, Ohio, and assigned to the Educational Novelty Company, Dayton, Ohio. Good condition, noting some discoloration of the enamel and a tab broken off one of the feet. With instructions and addition table, but no box.
