“B is the pan on which the coin rests, at a point above the beam. The coins are placed in a rouleau in the hopper C and the lowest one is pushed on to the pan B by a slide. While the coin is being moved the hanger D is held firmly by the forceps E to prevent the pan from being pushed sideways.” —Encyclopaedia Britannica
