ABSTRACT:
A rotary drive for swinging a heavy member between two extreme positions. The drive transmits a rotary force provided by a motor or similar device through a first rotatable shaft to a second rotatable shaft perpendicular to the first shaft and connected to the heavy member. The second shaft rotates in an oscillatory manner between the extreme positions in response to rotation of the first shaft. The member may thus be positioned at any suitable location in its travel by operating the motor unidirectionally. The first shaft rotates about a first axis of rotation and rotates an arm about a second axis of rotation that intersects the first axis at an angle between zero and 90 degrees non-inclusive. The arm is connected to a universal joint having three mutually perpendicular axes. The universal joint transmits forces from the arm to the second shaft.
