Abstract:
The Mechanical Rotor is a simple unique invention that salvages torque energy from excess linear kinetic energy produced by flowing rivers, streams, ocean currents, or blowing wind. The unique design of the invention salvages torque by the drag principal of Physics during part of a rotation. Rotation completion limits exposure to only a small aerodynamic surface into the pressure of the linear kinetic force. 
     The invention can be elongated, stacked, or clustered, and scalable, to accommodate any engineering design desired for using the salvaged torque to pump liquids, compress pneumatics, or generate electricity or any other useful purposes.

       BRIEF SUMMARY OF THE INVENTION 
       [0021]    The invention is a simple unique device, similar to a water wheel designed to gather usable torque energy from the excess linear kinetic force existing at natural moving substances such as flowing rivers, streams, tides, or ocean currents, etc., without constructing dams or special flow directing canals. The invention, as a vertical axis device, can gather torque energy from the linear kinetic force of blowing wind. 
       BACKGROUND OF THE INVENTION 
       [0022]    The original Mechanical Rotor invention U.S. PO Application No. 61/189,611, filed Aug. 21, 2008 is amended by this submittal. The original concept design remains the same 
         [0023]    Prior to the industrial revolution, the waterwheel was mankind&#39;s only means of harvesting and utilizing large quantities of energy. The waterwheel led to the development of the first practical windmill in about 50 AD. Each important in their own right, the waterwheel and the windmill have paved the way for the modern industrial turbine. 
         [0024]    Many devices suitable for gathering torque from wind are impractical or structurally unsound when encountering the force of flowing water. Many are overly complicated, using special spring recoil action and other such devices. Most become large and cumbersome when considered for commercial applications and few are of suitable scale for a small mountain Trout stream.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0072]    The following description illustrates the invented device as being functionally a waterwheel, rotating on a axis, harvesting torque energy from the positive drag force of flowing linear force of streams, rivers, ocean tides or wind. Adaptation of free swinging foils that self position according to the dynamic conditions to which they are subjected by the flowing linear force, creates a condition which develops a secondary method of extracting torque from flowing streams, rivers, ocean tides, or winds. 
         [0073]      FIG. 1  displays a vertical axis arrangement of the invention showing an Isometric sketch of the essential features to the Mechanical Rotor exposed by cutaway segments within an open 360 degree cage forming a structural frame. The view is at a 22.5 degree point of rotation with 0 degree being directly into the Linear Force  1  pressure. 
         [0074]      FIG. 1  view is applicable to a mirrored horizontal axis view or as either clockwise or counter clockwise Rotation Direction  15 . As displayed by  FIG. 1 , the Mechanical Rotor invention is bi-directional, with rotation direction controlled by some device such as a hydraulic, pneumatic, electric, or mechanical device controlled by an independent operator. 
         [0075]      FIG. 1  shows the Power Shaft  3  as the axel between two Wheel Plate  2 &#39;s as a solid one piece unit. Each end of Power Shaft  3  extends through Thrust Bearing  7  affixed in Support Plate  14  to facilitate rotation and provides access as needed to Power Shaft  3  by any torque using Device re: pump, generator, pulley, gearing or other such device. 
         [0076]    Symmetrically separating the Support Plate  14 &#39;s are six Frame Leg  13 &#39;s forming a structural cage which may be solidly mounted to some structure, such as a raft, tower, roof, etc. Three or more Frame Leg  13 &#39;s are required, dependant upon the structural strength needed for a specific use design. 
         [0077]    One or more of the Frame Leg  13 &#39;s may be a pipe or tube to provide a conduit for hydraulic/pneumatic, electrical, or instrumentation access the axis of the Mechanical Rotor invention. 
         [0078]    Four Hinge Shaft  5 &#39;s shown symmetrically, are attached between Wheel Plate  2 &#39;s using a Roller Bearing  8  at each end. 
         [0079]    Foil  4   a,  Foil  4   b,  Foil  4   c  and Foil  4   d.  Foil  4   a  and Foil  4   b  are solidly attached to each Hinge Shaft  5  and acted upon by the Linear Force  1  drag pressure. Foil  4   c  and Foil  4   d  are in the return position between the 180 degree and the 360 degree portion of a rotation. Foil  4   c  movement on Hinge Shaft  5  is illustrated by Foil Swing  15   a  arc. Three or more Hinge Shaft  5 &#39;s, each with a Foil  4  is required by the Mechanical Rotor invention. 
         [0080]      FIG. 2  represents the Mechanical Rotor invention in a horizontal axis position, perpendicular to the Linear Force  1  pressure of Flowing Water  27 . Two of the four Foil  4 &#39;s are shown submerged in Flowing Water  27  to the axel Power Shaft  3  and fabricated to move in a clockwise Rotation Direction  15 . 
         [0081]    The portion of the Mechanical Rotor above the Flowing Water  27  is exposed to natural air conditions, but for  FIG. 2  illustration purpose, the linear force of any wind is ignored because of the approximately 800 times energy differential between equal velocities of flowing water and blowing wind. 
         [0082]    Beginning at the 0 degree point of rotation, the Linear Force  1  exerts a positive drag on Foil  4 , causing a clockwise Rotation Direction  15 . As Foil  4  proceeds through the 45, 90, and 135 degree points until reaching the 180 degree point. 
         [0083]    The Linear Force  1 , passing the submerged side of Power Shaft  3 , applies pressure on the submerged side of Foil  4  facing the 270 degree point of rotation. The Linear Force  1  continues exerting pressure at each position of a Foil  4  as illustrated by the overlay at each 11.5 degree point of the Hinge Shaft  5  during rotation between 180 degrees and the 270 degree points. The overlaying plot also shows the Foil Tip Path  21  during the swing on Hinge Shaft  5 . 
         [0084]    The overlay plotting of  FIG. 2  demonstrates how the Linear Force  1  applies pressure on the Foil  4 , causing a pressure to be applied on Hinge Shaft  5  which then relays a force onto Power Shaft  3 , causing the Mechanical Rotor invention to develop Torque during Foil  4  swing to be aligned to be positioned at the 0 degree point of rotation. 
         [0085]    During the rotation between 270 degree to the 360 degree point, Foil  4  has a negative leading edge drag across the Hinge Shaft  5  diameter but also may have a positive aerodynamic lift of Foil  4  aerodynamic shape. 
         [0086]      FIG. 3  represents a Mechanical Rotor invention in a horizontal axis position, perpendicular to the Linear Force  1  pressures of Flowing Water  27 . The four Foil  4 &#39;s are shown to be totally submerged into the Flowing Water  27 , and fabricated to move in a clockwise Rotation Direction  15 . The view is applicable to a mirrored view or as either clockwise or counter clockwise Rotation Direction  15 . 
         [0087]      FIG. 3  represents the locations of a Foil  4  acted upon by the Linear Force  1  during a single rotation of the Mechanical Rotor invention. During the rotation, the Hinge Shaft  5  follows a circle represented by Foil Hinge Shaft Path  17 . 
         [0088]    Beginning at 0 degree, the Linear Force  1  exerts a positive drag force pressure on Foil  4 , causing a clockwise Rotation Direction  15 . The Linear Force  1  continues applying pressure as Foil  4  proceeds through 45, 90, and 135 degree points, until reaching the 180 degree point of the rotation. 
         [0089]    The Linear Force  1 , passing the submerged side of Power Shaft  3 , applies pressure on the submerged side of Foil  4 , between Power Shaft  3  and the Hinge Shaft  5  for Foil  4 . Each position of a Foil  4  is illustrated by an overlay of each 11.5 degree segment of the rotation between 180 degrees and the 270 degree point of rotation. The overlaying plot shows the Foil Tip Path  21  during the swing on Hinge Shaft  5 . 
         [0090]    The over lay during rotation from 180 degrees to 270 degrees points, allows the Linear Force  1  to apply pressure on the leeward side of Foil  4 , causing a pressure to be applied on Hinge Shaft  5  which then is relayed onto Power Shaft  3 , causing the Mechanical Rotor invention to develop Torque. 
         [0091]    Foil  4  continuing between the 270 degree rotation point to the 360 degree point of rotation, the Foil  4  is a natural directional vane, causing the invention to be constantly aligned toward Linear Energy  1 . 
         [0092]    During the 270 degree rotation point to the 360 degree point of rotation, Foil  4  will have a negative leading edge drag across Hinge Shaft  5  diameter and a positive aerodynamic lift force, because of the aerodynamic shape of Foil  4 . 
         [0093]      FIG. 4  is a circumferential section Plan view of the Mechanical Rotor invention. Sectional arrow direct reference view of the axial Elevation displayed at  FIG. 5 . The  FIG. 4  drawing orientation aligns into Linear Force  1  housed in a cage open to 360 degree of a varying Linear Force  1  pressure. 
         [0094]      FIG. 4  shows six symmetrically located Frame Leg  13 &#39;s around Support Plate  14 . Two or more Frame Leg  13 &#39;s are required for stable structural fabrication. Support Plate  14  is sized to accommodate the symmetrically located Frame Leg  13 &#39;s being clear of any contact by the swing of a Foil  4  on Hinge Shaft  5 , no matter what direction Linear Force  1  may be traveling. 
         [0095]      FIG. 4  displays Thrust Bearing  7  in Support Plate  14  accommodating Power Shaft  3  which is solidly connected to Wheel Plate  2  forming a part of the Mechanical Rotor&#39;s spool shape containing Foil  4 &#39;s. Displayed by  FIG. 4  are Foil  4   a,  Foil  4   b,  Foil  4   c  and Foil  4   d,  symmetrically oriented around Wheel Plate  2  in a clockwise Rotation Direction  15  with each connected to a Hinge Shaft  5 . 
         [0096]    Foil  4   a  is located at the 0 degree point of a rotation of the Mechanical Rotor invention. Foil  4   b  is at the 90 degree point of rotation and receives maximum pressure from Linear Force  1 . Foil  4   c  is at the 180 degree point of rotation, ending exposure to the pressure from Linear Force  1  on the windward side and beginning receiving pressure from Linear Force  1  on the leeward side. 
         [0097]    Foil  4   d  is shown with Foil  4   d &#39;s Hinge Shaft  5  being the leading edge for return from the 270 degree point of rotation to the 0 degree point of rotation. During rotation from the 180 degree to the 270 degree point of rotation, Foil  4   d  made a Foil swing  15   a  of 180 degrees on the Hinge Shall  5 . During the time period amassing Foil swing  15   a,  Foil  4   d  exerted a measurable pressure on Hinge Shaft  5  which relayed a measurable amount of torque pressure to Power Shaft  3  via Wheel Plate  2 . 
         [0098]      FIG. 5  is an axial view of the Mechanical Rotor invention displayed in a vertical position. Section arrows direct reference view of  FIG. 4  circumferential section Plan.

Umbilical Line  25  is shown to represent any method of conveying any substance such as hydraulic, pneumatic, electricity, instrumentation controls, a mechanical arm, etc. to a convenient point of physical use purpose. 
         [0103]    Changing the axis length the Mechanical Rotor invention as shown by  FIG. 5  will proportionally change the torque developed from Linear Force  1 . 
         [0104]      FIG. 6  is a circumferential section Plan view of the Mechanical Rotor invention. Sectional arrow direct reference view of the axial Elevation displayed at  FIG. 5 .

         [0106]      FIG. 6  displays Thrust Bearing  7  housed in Support Plate  10  accommodating Power Shaft  3  which is solidly connected to Wheel Plate  2  forming a part of the Mechanical Rotor&#39;s spool shape containing Foil  4 &#39;s. Displayed by  FIG. 6  are Foil  4   a,  Foil  4   b,  Foil  4   c  and Foil  4   d,  symmetrically oriented around Wheel Plate  2  in a clockwise Rotation Direction  15  with each connected to a Hinge Shaft  5 .

         [0108]    During rotation from the 180 degree to the 270 degree point of rotation, Foil  4   d  made a Foil swing  15   a  of 180 degrees on the Hinge Shaft  5 . During the time period amassing Foil swing  15   a , Foil  4   d  exerts a measurable pressure on Hinge Shaft  5  which relays a measurable amount of torque pressure to Power Shaft  3  via Wheel Plate  2 . 
         [0109]      FIG. 7  is an axial view of the Mechanical Rotor invention displayed in a vertical position. Sectional arrow directs reference view of  FIG. 6  circumferential section Plan.
