Fluid forcing device

A fluid forcing device comprising:

• a central axle;
• a multiplicity of rotatable elements fitting snugly together, each element rotating around the central axle, each element having a pin protruding in front and a curved slot of preset length in back, the pins and slots cooperating to limit movement of adjacent elements, each element having two radial arms terminating in a roller, and each element having a long downward pointing vertical part that is immersed in a fluid;
• two sets of multiple wedges, each wedge having a curved edge to provide a surface for several of said rollers to bank against so that one wedge of one set will cause one group of arms and thereby also the immersed vertical parts materially attached to them to form the apex of a wave while one wedge of the second set will cause another group of arms and thereby also the immersed vertical parts materially attached to them to form the trough of the same wave;
• a rigid mechanical connection between the first rotatable element and the last rotatable element to maintain the alignment of the above said wedges relative to the first and last rotatable elements;
• two spring strips to force the above said rollers to bank against the wedges;
• two sets of guiding tracks, one set for each said set of wedges, to guide the movement of the wedges and to locate the wedges and thereby the apex and trough of the wave;
• two drive systems, one drive system for each said set of wedges, to move and to synchronize the position of the wedges which, in turn, move the wave as a whole;
• a tray to support the central axle, drive systems, and tracks;
• means to power the movement of the drive systems.
