A traversing blade rotary propeller useful as a propulsion system for various types of boats and aircraft or as a wind or water actuated turbine. A traversing blade rotary propeller of this type includes a stationary main shaft, a mount to which an end of the stationary main shaft is affixed, a central housing structured to carry a pair of alternately disposed, perpendicularly projecting radial arm shafts, and where the device is used as a propulsion system, power means for rotation of said central housing relative to the fixed axis formed by said stationary main shaft. A pair of propeller shafts extend perpendicularly from an end of each of said radial arm shafts, and flat propeller blades are attached to each. The inboard ends of each of the radial arm shafts are operatively engaged with the stationary main shaft, and the outboard ends are operatively engaged with the propeller shafts, as via gears such that rotation of the central housing produces rotation of the propeller shafts. The propeller shafts are mounted perpendicular to the radial arm shafts, and equally and oppositely deflected at an angle relative to a line passing parallel to the axes of the radial arms to perpendicularly intersect the stationary main shaft. During rotation the propeller blades maintain a fixed vertical (or horizontal) orientation while the outwardly faced edges thereof oscillate in equal and opposite directions, one counterbalancing the other, across the swath defined by the circle made by the path defined by the outer terminal ends of the radial arms which revolve about the stationary main shaft.

A traversing blade rotary propeller useful for the application of laterally acting forces upon a fluid medium to produce propulsion as by attachment via a mount to a craft for propulsion of the craft, which comprises: a stationary main shaft, one end of which is suitable for attachment to the mount,
A traversing blade rotary propeller useful for the application of laterally acting forces upon a fluid medium to produce propulsion as by attachment via a mount to a craft for propulsion of the craft, which comprises: a stationary main shaft, one end of which is suitable for attachment to the mount, the other of which is provided with gear means, a housing, inclusive of a central gear means housing into which the gear means end of said stationary main shaft is extended and supported, rotatably mounted upon said stationary main shaft, and peripheral gear means housings alternately disposed and adjoined to said central gear means housing, a pair of radial arm shafts each end of which carries gear means, alternately disposed, radially mounted, each extended from said central gear means housing to said peripheral gear means housings, a gear means end of each radial arm shaft extending into said central gear means housing to operatively engage the gear means end of said stationary main shaft such that relative movement between the engaged gear means ends of the radial arm shafts and the stationary main shaft will cause the radial arm shafts to rotate about their own axes one relative to the other in equal and opposite directions, the opposite end gear means of a radial arm shaft extending into the peripheral gear means housings, a pair of propeller blade shafts each mounted perpendicular to a radial arm shaft, each being equally and oppositely deflected at an angle such that the axes thereof are non-parallel with the axis of the stationary main shaft, and define equal and opposite angles relative to a line parallel with the axes of the radial arm shafts which perpendicularly intersects the stationary main shaft, one each of which carries an affixed gear means, the gear means end of each propeller blade shaft extending into the peripheral gear means housings such that a gear means thereof is operatively engaged with a gear means of each of said radial arm shafts, a pair of flat propeller blades, one each of which is mounted upon an end of each of said propeller blade shafts, similarly directionally oriented one with respect to the other, and a power means for applying force to rotate the central gear means housing relative to the stationary main shaft whereby the radial arm shafts are rotated to drive the propeller blade shafts in a direction opposite to that in which the central gear housing is rotated and to the same degree, the propeller blades one relative to the other in turn being maintained in fixed orientation as the central gear means housing is rotated relative to the stationary main shaft, while the flat propeller blades as they are moved along a continuous circular path around the axis of the stationary main shaft are oscillated in equal and opposite directions across the swath defined by the circle, each like the caudal fin of a fish or the fluke of a whale in propulsion.
