Abstract
Abstract An electrically powered vehicle having fan-driven generators or alternators selectively individually engageable by the driver such that as the speed of the vehicle increases and the air reaching the fan increases, additional generators may be powered. A wedge cam is adapted to move between rows of staggered generators to progressively move them into engagement with opposite belt portions of a continuous belt. Two belts are provided for doubling the number of generators.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
A vehicle having a rechargeable electrical power source, comprising, a plurality of electrical generators operatively connected to said rechargeable electrical power source, a fan at the front of said vehicle in a passageway opening to the front such that as said vehicle moves forwardly air will pass through said passageway causing said fan to rotate, drive means for selectively interconnecting said fan with said generators, actuating means for selectively moving each of said generators successively into driving engagement with said drive means whereby the output power of said fan may be correlated to the air input power, and said drive means including a continuous belt engaging a pulley on said fan and selectively engaging pulleys on said generators, said drive means including an idler pulley opposite said fan and the opposite belt lengths are adapted to selectively engage said generator pulleys positioned between said idler pulley and said fan.
Claim 2
Dependent Claim
149 words
A vehicle having a rechargeable electrical power source, comprising, a plurality of electrical generators operatively connected to said rechargeable electrical power source, a fan at the front of said vehicle in a passageway opening to the front such that as said vehicle moves forwardly air will pass through said passageway causing said fan to rotate, drive means for selectively interconnecting said fan with said generators, actuating means for selectively moving each of said generators successively into driving engagement with said drive means whereby the output power of said fan may be correlated to the air input power, and said drive means including a continuous belt engaging a pulley on said fan and selectively engaging pulleys on said generators, said drive means including an idler pulley opposite said fan and the opposite belt lengths are adapted to selectively engage said generator pulleys positioned between said idler pulley and said fan.
Claim 3
Dependent Claim
149 words
A vehicle having a rechargeable electrical power source, comprising, a plurality of electrical generators operatively connected to said rechargeable electrical power source, a fan at the front of said vehicle in a passageway opening to the front such that as said vehicle moves forwardly air will pass through said passageway causing said fan to rotate, drive means for selectively interconnecting said fan with said generators, actuating means for selectively moving each of said generators successively into driving engagement with said drive means whereby the output power of said fan may be correlated to the air input power, and said drive means including a continuous belt engaging a pulley on said fan and selectively engaging pulleys on said generators, said drive means including an idler pulley opposite said fan and the opposite belt lengths are adapted to selectively engage said generator pulleys positioned between said idler pulley and said fan.
Claim 4
Dependent Claim
149 words
A vehicle having a rechargeable electrical power source, comprising, a plurality of electrical generators operatively connected to said rechargeable electrical power source, a fan at the front of said vehicle in a passageway opening to the front such that as said vehicle moves forwardly air will pass through said passageway causing said fan to rotate, drive means for selectively interconnecting said fan with said generators, actuating means for selectively moving each of said generators successively into driving engagement with said drive means whereby the output power of said fan may be correlated to the air input power, and said drive means including a continuous belt engaging a pulley on said fan and selectively engaging pulleys on said generators, said drive means including an idler pulley opposite said fan and the opposite belt lengths are adapted to selectively engage said generator pulleys positioned between said idler pulley and said fan.
Claim 5
Dependent Claim
34 words
The structure of claim 1 wherein said actuating means includes a cam member adapted to move between first and second rows of generators to move them outwardly for engagement with said opposite belt lengths.
Claim 6
Dependent Claim
36 words
The structure of claim 1, wherein said generators are staggered such that as said cam member is moved progressively between said rows of generators said generators will progressively be moved into engagement with said belt lengths.
Claim 7
Dependent Claim
28 words
The structure of claim 3 wherein springs are provided for biasing said generators out of engagement with said belt lengths against the opPosing action of said cam member.
Claim 8
Dependent Claim
27 words
The structure of claim 4 wherein said actuating means further includes a lever connected to said cam member and accessible in the driver''s compartment of said vehicle.
