" The engraving herewith illustrates a re- versible honey-extractor made and patented by E. L. Goold & Co., of Brantford, Ont. It can be made either as a two-frame or four-frame machine. For a two-frame Langstroth a can 233^ inches in diameter is required; for a four-frame the diameter must be 27 inches. The baskets are reversed by means of a positive lever motion. The levers radiating from the center shaft work in a slot in the bottom of the comb pockets. Reversing the crank reverses the center shaft, which in turn revolves the levers a little way, and thus causes the pockets to be swung E. L.
