ABSTRACT:
A swim-in-place pool has horizontal inner and outer circulating waterways arranged in such manner that a portion of the inner waterway coincides with a portion of the outer waterway. The non-coincident portion of the inner waterway then provides a swimming space. A plurality of impeller blades are suspended in a spaced series within the coinciding portion of the two waterways, each of the blades in its operative condition extending transversely of that waterway and occupying substantially all of its cross-sectional area. A power drive advances the blades in unison along the coinciding portion of the two waterways so that a rather fixed body of water is captured between each two adjacent blades and advanced therewith. A diversion structure adjacent the entry of the non-coincident portion of the inner waterway diverts a continuous flow of water in a relatively non-turbulent state into and through the swimming space.
