5513. Clery, R. W. March 7. Propelling by reciprocating plates.-Ships and boats are propelled by means of collapsable fanlike saucers on either side of the rudder, each composed of a number of sections g<1> connected by jointed arms h to a rod c, which passes through a stuffing-box and is reciprocated by a piston e in a cylinder f. On being thrust outwards, the sections g<1> expand and propel the ship, and, when drawn in, they collapse.
