Windmill with multiple double-acting piston/cylinder compressor system and apparatus and method of mounting multiple windmill blades to enhance performance

Abstract

A windmill compressor apparatus has multiple double acting piston/cylinders actuated by the windmill. The windmill additionally has multiple pairs of blades to enhance power output and lift.

What is claimed is:  
     
         1 . A windmill compressor apparatus comprising: 
 windmill means mounted to a windmill shaft to rotate said shaft in response to air flow through said windmill means;    multiple double-acting piston/cylinder means each having a piston operating within a cylinder to compress air upon movement of the piston within the cylinder;    each of said cylinders having a piston shaft connected to said piston therein; said piston shaft extending from said cylinder;    drive means connecting said piston shafts to said windmill shaft to drive said piston shafts in response to rotation of said windmill shaft; and    conduit means connected to the piston/cylinder means to permit the flow of air into said cylinders to receive compressed air from said cylinders.    
     
     
         2 . The windmill compressor apparatus of  claim 1  further comprising positioning the multiple double-acting piston/cylinder means such that the cylinders are radially space from one another.  
     
     
         3 . A windmill compressor apparatus as set forth in  claim 1  wherein said cylinders are of different diameters.  
     
     
         4 . The windmill compressor apparatus of  claim 3  wherein pressure relief valves are disposed in discharge lines exiting said cylinders of different diameters.  
     
     
         5 . The windmill compressor apparatus of  claim 4  wherein the pressure relief valve for the cylinder with the largest diameter is set to be actuated at a pressure which is less than the pressure relief valve for the cylinder with the smaller diameter.  
     
     
         6 . The windmill compressor apparatus of  claim 1  wherein the drive means comprises a crank arm attached to the windmill shaft to rotate therewith; said crank arm having a portion thereof connected to the piston shafts to rotate said piston shafts, thereby withdrawing and inserting the shafts with respect to the cylinders to compress air.  
     
     
         7 . The windmill compressor apparatus of  claim 1  wherein the crank arm has a portion thereof opposite to the end which is connected to the piston shafts, which portion acts as a counterbalance to the pistons.  
     
     
         8 . The windmill compressor apparatus as in  claim 1  further comprising multiple pairs of windmill blades.  
     
     
         9 . The windmill compressor apparatus of  claim 8  wherein the multiple pairs of blades are attached to multiple hubs on said windmill shaft.  
     
     
         10 . The windmill compressor apparatus of  claim 9  wherein the blades in each pair of windmill blades are interconnected with braces.  
     
     
         11 . A windmill compressor apparatus comprising: 
 windmill means mounted to a windmill shaft to rotate said shaft in response to air flow through said windmill means; the windmill further comprising multiple pairs of windmill blades.    
     
     
         12 . The windmill compressor apparatus of  claim 11  wherein the multiple pairs of blades are attached to multiple hubs on said windmill shaft.  
     
     
         13 . The windmill compressor apparatus of  claim 11  wherein the blades of each pair of windmill blades are interconnected with braces.
