Abstract: A self-renewing electrically driven vehicle has electro-generating units 1 and 2. Unit one has an electrically charged starter battery, a first electric motor and a dynamo-electric generator connected to a first road-wheel axle. Unit two has a second electric motor, two initially uncharged batteries and two similar generators. Unit one starts the automobile and maintains it for a short time until unit two can operate the vehicle. As a result of a rotary motion transferring device, while the vehicle is in motion, the generator of unit one receives mechanical energy generated by the first road-wheel axle and converts that mechanical energy into electrical energy which automatically flows into the starter battery to recharge it. From the inception of the vehicle's movement and onward, each generator of unit two receive mechanical energy from the second road-wheel axle that they are connected to and convert this energy into electrical energy which they send to the two storage batteries of unit two.

Abstract: A vehicle having an electro-generating system which includes a dynamoelectric generator. The shaft of the dynamoelectric generator is linked directly or indirectly with the rotating axle of the road wheels of the vehicle, preferably via a mechanical turns amplifier. The turns amplifier will multiply the rotation rate of the electro-generating system and increase the production capacity of electric power. The dynamoelectric generator can be utilized to recharge a storage battery driving the vehicle while the car is in motion, especially automatically when the vehicle is going down hill. The vehicle's electric motor can be driven directly from a dynamoelectric generator in place of a storage battery after the vehicle is moving. In railroad cars (freight and passenger) the electro-generating system can be utilized to charge storage batteries, with their electricity utilized for other electro-energy requirements.

Abstract: A swinging toy comprises a U-shaped frame having two spaced parallel support rods and a connecting fulcrum rod. A figure comprises a body member simulating a head and shoulders with two arm members rotationally connected to the body member at the simulated shoulders. An outer string line is connected between the parallel support rods near one end of the frame and passes through inner openings of the arm members. An inner string line is connected between the parallel support rods parallel to and adjacent the outer string line and passes through outer openings of the arm members. When the frame is placed in a vertical position with the figure at the top, gravity will cause the body member to move around the inner and outer string lines to take an upside-up position below the inner string line, which causes the inner and outer string lines to cross each other.
