A length of bar stock is screw-threaded at two different thread pitches along respective fractions of its total length. Two bodies are internally threaded at the different pitches. Each body engages the bar stock along the portion of its length which is threaded at the corresponding pitch, and the bodies move along the bar at different rates of travel from one another in response to rotation of the bar. The bodies are mechanically attached by means of pivot connections to an elongated member, the two pivotal connection points defining an axis on the member. Rotation of the bar stock drives the pivotal connection points on the elongated member in substantially the same direction transverse to the axis, but at different speeds, with the result that substantially pivotal motion is generated about an unattached point on the axis of the elongated member, on the other side of the slower moving pivotal attachment point from the faster.
An apparatus for generating substantially pivotal motion of an axis of a member about a remote point on the axis, comprising
An apparatus for generating substantially pivotal motion of an axis of a member about a remote point on the axis, the apparatus being of the type where two points on the axis are driven along respective paths transverse to the axis at such differential rates of travel that the remote point on the other side of the slower driven point from the faster experiences minimal spatial displacement as the driven points are displaced, comprising
