## Title
Transportation and power generating system of gravity and leaf springs

## Abstract

Two weights and or springs mounted on two pivoted beams. A short end of each beam is interconnected with a gearbox by a crank and trace. The gearbox is interconnected with two other ends of the beams by linkages. An electric starter with battery imparts kinetic energy to lift one weight and let the other weight descend. The gearbox regulates the oscillation of two beams. The operator turns the electric starter off after the system is started. An output shaft imparts rotary motion of the gearbox to drive a vehicle, an airplane, or an AC generator.

The movable device at least partially extends through an opening in the housing and is positioned transversely within the path of travel of vehicles moving along the road for engaging the vehicles seriatim to be set into motion thereby. A coupling device connects drivingly the movable device and a generating device for transmitting drivingly the motion of the movable device to the generating device, such as an electrical generator. A flywheel is installed for rotation about its axis for storing the energy in response to the movable device to provide a more continuous production of energy from the generating device.
U.S. Pat. No. 124,172 class 290/1R issued on Jan. 25, 1988 to Sen; Asim K. This invention relates to a scheme for generating electricity using gravitational energy. The scheme uses a set of massive underground spinning wheels, each wheel being fitted with a mechanism to receive and transmit gravitational torque pulses from a passing vehicle to keep the wheels in motion. The mechanism used to apply the torque pulses to the spinning wheels consists of a stepping board, a hollow cylindrical rod disposed vertically and a shoe attached to the lower end of the vertical rod by a hinge with the upper end of the rod protruding above the ground surface. A steel linkage connecting the stepping board and the lower part of the shoe is used for initial positioning of the shoe. Both the stepping board and the protruding end of the vertical rod are kept in their initial upward positions by means of two springs. The electricity is generated by using each spinning wheel in combination with an appropriate gear system to act as the prime mover of an alternator.

A transmission mechanism is added between the circulating device and the working shaft to increase the rotational speed of the working shaft.
U.S. Pat. No. 5,929,531 issued on July 1999 class 290/53 to Lagno describes, a lunar tide powered hydroelectric plant of variable size and power generation capacity for basing on land or in tide waters. The basic collection of mechanical power is done by torsion spring bank units positioned on a concrete barge. The land-based plant obtain oscillatory motion from a notched frame. The tide water based plant obtains oscillating motion from notched piling. An individual torsion spring bank unit can comprise columns of horizontally aligned torsion springs based on a row of torsion springs of a bottom control cell. The tide and wave motion is transferred to the torsion spring banks.
A computer system manages the release of each torsion spring column to a drive shaft of a generator to produce electrical power. The computer system also permits the conversion of kinetic energy by reversing the gearing system for the upward motion of the floating barge so as to obtain a constant input of kinetic energy to the generator.

U.S. Pat. No. 4,661,716 issued on April 1987 class 290/53 to Chu describes, an unlimited and continuous pneumatic generating system to be driven with the sea-wave force. This system can effectively absorb the motive force of sea-waves from almost any direction, and can convert that force into a mechanical force, which is further converted into a pneumatic force. The pneumatic force is transmitted to the shore, being divided into two portions, of which one portion -A- is used for generating electric power, while the other portion -B- is to be stored up as a spare energy, which may be used upon having no sea-wave force to be absorbed from the sea for directly generating power.

A pin 27 for pivoting the lower end 29 of the connecting rod 31 with the Y-shaped part 13. A cup 35 for Installation the upper end 33 of the connecting rod 31 on the crank 37. A crankshaft 38 is installed in the gearbox 24 for imparting motion of crank 36 and crank 37 to the gearbox 24. The gearbox 24 having an automatic transmission mechanism as FIG. 7a showing for imparting rotary motion from the crankshaft 38 to a shaft 25 and an output shaft 47. The shaft 25 imparts rotary motion to pulleys 19 and 18 that are fixedly secured to an end of the shaft 25. A vertical frame 23 is installed on the system's frame 60 for fixing a horizontal frame 22 thereon. A pulley 21 is free to rotate and it is installed on the right end of the horizontal frame 22 and a chain 17 is trained on the pulley 21. A pulley 20 is installed on the left end of the horizontal frame 22 and the pulley 20 is free to rotate and a chain 16 is trained on the pulley 20. The chain 17 is be fixed on pulley 19 by an end and a second end 51 is fixed on an end of a coil spring 53 and a second end of the coil spring 53 is fixed on the end 11 of the beam 2 and the chain 17 lifts the end 11 to up when the end 9 is descendant. When the shaft 25 rotates to rotary direction thereby the chain 17 coil round the pulley 19 to lift the end 11 to up; on the rotation of the shaft 25 to the opposite rotary direction the chain 17 uncoils to let the end 11 and weight 4 descend. Because, two pulleys 19 and 18 are fixedly secured on the shaft 25, therefore, on the rotation of the pulley 19 to any direction also the pulley 18 is rotating to the same direction for lifting the end 9 to up by the chain 16 that coils round the pulley 18. On the lifting of the end 9 by the chain 16; the coil spring 52 is strained approximately one inch or suitable length when the straining of the chain 16 is equal about three times the weight 3. When the distance between the end 9 and the bolster 14 is one inch or suitable distance and the distance between the end 11 and the system's frame 60 is one inch approximately or suitable distance; the automatic transmission mechanism inside the gearbox 24 changes the rotary direction of the shaft 25 to reverse direction for rotation two pulleys 19 and 18 to opposite direction. The chain 16 is slack and the coil spring 52 is released to let the end 9 descends and the chain 17 coil on the pulley 19 for lifting the end 11 for reversion the movement of beam 1 and beam 2. An end 50 of the chain 16 is connected with the coil spring 52. An end 51 of chain 17 is connected with a coil spring 53. A brake device 40 is installed on the body of the gearbox 24 or on the system's frame 60 and a brake disk 39 that is fixedly secured on the crankshaft 37 for stopping the system.

The alternator 49 for recharging a battery of the electric starter 41.
On the operation, the operator turns the electric starter on for starting the system; the gear 42 engages with the gear 43 for imparting rotary motion to the crankshaft 38 and the shaft 25 through the shaft 47 and gearbox 24 as FIG. 7a showing and the rotary direction of the shaft 25 is according to the position of both two beams. If the end 9 having upper extreme position and the end 11 having lower extreme position; the automatic transmission mechanism inside the gearbox 24 rotates the shaft 25 to rotary direction thereby unwinding the chain 16 off the pulley 18 for descending the end 9. The Y-shaped part 12 oscillates and the connecting rod 30 convert the oscillation of the end 7 to rotary motion of the crankshaft 38 through the crank 36. The chain 17 coils round pulley 19 for lifting the end 11 of beam 2. The connecting rod 31 imparts the oscillation of the end 8 to crank 37 for rotation the crankshaft 38; because, the winding speed of the chain 17 round the pulley 19 is faster than the speed of the end 11 to up, therefore, the spring 53 is strained when the straining of the chain 17 is equal to three times the weight 4. The automatic transmission mechanism inside the gearbox 24 changes rotary direction of the shaft 25 into opposite rotary direction when the distance between the lifted end 11 and bolster 15 is one inch approximately or suitable distance and the distance between the end 9 and the system's frame 60 is one inch approximately or suitable distance. The chain 16 coils round pulley 18 for lifting the end 9 from down to up and chain 17 unwind off pulley 19 for descent the end 11.
