ABSTRACT:
A mechanism for generating oscillatory motion omnidirectionally transforms rotating motion in which the rotating member is continuously rotated unidirectionally into any number of simultaneous arcuate motions intersecting at predetermined angles. This mechanism includes a disk-shaped body rotatably mounted and swept in a circle so that it completes two periods of rotation over the course of one period of sweep. The altitude of the disk-shaped body always intersects a point on an imaginary line, regardless of the angle of inclination of the disk-shaped body. This imaginary line is perpendicular to the circularly swept path of the disk-shaped body at the center of the circularly swept path. Points on the circumferential edge of the disk-shaped body describe an infinite number of arcs as they move around the circularly swept path. These arcs intersect at a common point from an infinite number of angles. Any number of desired arcs intersecting at any angle can be obtained by selecting points on the circumferential edge of the disk-shaped body describing those desired arcs. This apparatus is the basis for improvements in a variety of existing devices such as mixers, grinders, drills, pendulum devices, centrifuges, signal lights, electric shavers, massagers, scanning devices such as ultrasonic, x-ray, radar and computer memory scanners, optical cameras and projectors, dispersing devices, assembly lines, robots, energy bombardment chambers, and amusement rides.
