Claim 8

Variable directing apparatus for a fluid stream, comprising: means for defining a flowing fluid stream; movable fluid directing means for changing the direction of said stream on movement of said directing means; fluid propelled rotatable means in said stream for moving said directing means due to the fluid force-caused rotation of said rotatable means; adjustable fluid blocking means for blocking said stream to said rotatable means to a selected variable degree thereby to regulate the speed of rotation of said rotatable means and thus the movement of said fluid directing means, said blocking means comprising an adjustable deflector movable between extreme positions of a position of substantially complete blocking of the air flow to said rotatable means for preventing substantial rotation thereof and a substantially non-blocking position to permit full impingement of said fluid stream portion on said fluid propelled rotatable means; and a brake means operatively engaging said rotatable means when said blocking means is in its substantially complete blocking position for locking the rotatable means against rotation.

Claim 9

Variable directing apparatus for a fluid stream, comprising: means for defining a flowing fluid stream; movable fluid directing means for changing the direction of said stream on movement of said directing means; fluid propelled rotatable means in said stream for moving said directing means due to the fluid force-caused rotation of said rotatable means; adjustable fluid blocking means for blocking said stream to said rotatable means to a selected variable degree thereby to regulate the speed of rotation of said rotatable means and thus the movement of said fluid directing means, said blocking means comprising an adjustable deflector movable between extreme positions of a position of substantially complete blocking of the air flow to said rotatable means for preventing substantial rotation thereof and a substantially non-blocking position to permit full impingement of said fluid stream portion on said fluid propelled rotatable means; and a brake means operatively engaging said rotatable means when said blocking means is in its substantially complete blocking position for locking the rotatable means against rotation.

Claim 10

The apparatus of claim 7 wherein there are provided operating handle means on said directing apparatus accessible from the exterior thereof for said adjusting of the fluid blocking means and interconnecting apparatus between said handle means and said adjustable fluid blocking means and said brake means for applying said brake means upon movement of said fluid blocking means to substantially completely blocking position.

Claim 11

The apparatus of claim 8 wherein certain of said paddles are provided with fluid permeable opening means for permitting direct impingement of said fluid on successive paddles.

Claim 12

The apparatus of claim 1 wherein said rotatable means is provided with spaced fluid flow responsive means positioned in said fluid stream for rotating said rotatable means and thus said directing means.

Claim 13

The apparatus of claim 1 wherein said adjustable means comprises adjustable fluid blocking means having an operating handle adjacent said movable fluid directing means for blocking said stream to said movable means to a selected variable degree thereby to regulate the speed of movement of said movable means and thus the movement of said fluid directing means.

Claim 14

In a variable directing apparatus for a fluid stream having means for defining a flowing fluid stream, movable fluid directing means for changing the direction of said stream on movement of said directing means, and fluid propelled movable means in said stream for moving said directing means due to a fluid force-caused movement of said movable means, the improvement comprising adjustable fluid blocking means for blocking said stream to said movable means to a selected variable degree thereby to regulate the speed of movement of said movable means and thus the movement of said fluid directing means; and means for dividing said stream into separate portions and directing one portion to said fluid directing means and the other portion to said movable means, said fluid blocking means being disposed to control the flow of only said second stream portion.

Claim 15

In a variable directing apparatus for a fluid stream having means for defining a flowing fluid stream, movable fluid directing means for changing the direction of said stream on movement of said directing means, and fluid propelled movable means in said stream for moving said directing means due to a fluid force-caused movement of said movable means, the improvement comprising adjustable fluid blocking means for blocking said stream to said movable means to a selected variable degree thereby to regulate the speed of movement of said movable means and thus the movement of said fluid directing means; and means for dividing said stream into separate portions and directing one portion to said fluid directing means and the other portion to said movable means, said fluid blocking means being disposed to control the flow of only said second stream portion.

Claim 16

In a variable directing apparatus for a fluid stream having means for defining a flowing fluid stream, movable fluid directing means for changing the direction of said stream on movement of said directing means, anD fluid propelled movable means in said stream for moving said directing means due to a fluid force-caused movement of said movable means, the improvement comprising: adjustable fluid blocking means for blocking said stream to said movable means to a selected variable degree thereby to regulate the speed of movement of said movable means and thus the movement of said fluid directing means; and means for dividing said stream into separate portions and directing one portion to said fluid directing means and the other portion to said movable means, said fluid directing means and movable means being disposed in side-by-side relationship.
