A device (15, 18) for use in a body of water (10) as one of a plurality of such devices assembled in axial alignment with one another along a restraining element (16) to suppress incident wave turbulence, the devices having a hub (19, 119) adapted to receive the restraining element, a plurality of planar vanes (23, 123) for directing incident water extending generally radially and axially of the hub, an annular baffle (21, 121) disposed proximate the radial extremity of the vanes, a web (20, 120) for suppressing turbulence extending radially of the hub and oriented substantially perpendicular to the vanes, and elements (30, 130) on the hub precluding relative rotation between adjacent of such devices assembled along the restraining element.

Aquatic turbulence suppression device

A kickboard for supplementing the buoyancy of a swimmer when grasped by a swimmer's hands including a generally elongate rectangular member (11) of relatively lesser thickness, one side (20) of said member being a generally planar surface, the other side (30) of said member having a plurality of spaced depressions (35) having wall sections (36, 37) thereof extending a substantial portion of the thickness of said member for providing substantial structural rigidity, some of said depressions having a portion (38) thereof attached to said one side (20) of said member for enhancing the strength and rigidity of said member and some of said depressions being positioned proximate the periphery of said member to facilitate gripping by a swimmer's hands.

Training device for swimmers

A buoy for supplementing the buoyancy of a swimmer's legs comprising, a unitary foam member (11) having a flexible generally water impervious skin (41) adapted for engagement with and selective retention by the legs of a swimmer, the foam member having spaced cylindrical elements (12,13), being of generally prolate circular cross section (14,15), the circular cross section (15) of one of the cylindrical elements being substantially smaller than the circular cross section (14) of the other of the cylindrical elements and a shank (25) spacing and joining the cylindrical elements and being substantially narrower than the circular cross section of either of said cylindrical elements (12,13).

Leg buoy for training swimmers

A chlorinator (10) for chemically treating with tablets (T) water in a swimming pool having a water recirculating system with a pump with output and input sides including, a cannister (11) having a bottom (12), a top (13) with an opening (15) and connecting sides (14), a lid (20) for effecting fluid-tight sealing of the top opening of the cannister, an inlet (25) supplying water to the cannister from the output side of the pump, an outlet (40) transferring treated water from the cannister to the input side of the pump, a support (75) angularly disposed between the bottom of the cannister and the connecting sides to submerge a substantially uniform quantity of the tablets in the water, and a controller (45) adjustable relative to the cannister to establish the water level (L) in the cannister and supply uniformly treated water through the outlet.
