A nutation frame is mounted on a base at a fulcrum connection for limited angular movement about those axes which are perpendicular to a nutation axis and is restricted against cumulative rotary movement about the nutation axis. The nutation frame rigidly connects reciprocating connections on axes approximately parallel to the nutation axes and radially spaced therefrom and a number designed for circular motion about said axis being axially displaced from said fulcrum. The frame can thus convert circular movement about the nutation axis to reciprocating movement or vice versa. |
