ABSTRACT:
Apparatus is provided for moving an object in an oscillatory manner and in an arcuate path through the use of a fluid. The apparatus basically includes a hollow member or elongate tube having a curved portion and means for supplying fluid in pulses or at an increasing rate and then at a decreasing rate of flow to the tube on one side of the curved portion. The change in velocity of the fluid and the rate of change cause the movement of the tube due to inertia and, to a lesser extent, friction of the moving fluid within the tube. The density of the fluid also has a substantial effect on the movement of the tube, although gas alone will cause movement. The object to be moved is engagable by the tube and is usually supported by it. The object moved by the tube and fluid can take many forms, including signs, ornaments, figures, chimes, and clock dials.
