Claims
- 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.
