`ABSTRACT
`
`A dynamo electric machine is connected, over a claw
`clutch, to the driving wheels of the vehicle; an internal
`combustion engine is connected over a slip clutch with
`the shaft of the electric motor,
`to permit selective
`drive of the vehicle either electrically, or by the inter-
`nal combustion engine and, upon suitable intercon—
`nection of the dynamo electric machine, simulteneous
`re-charging of a storage battery when the vehicle is
`not driven by the dynamo electric machine acting as a
`motor.
