ABSTRACT:
BACKGROUND OF THE INVENTION
1) Field of the Invention
The field of this invention relates to motors and more particularly to a motor which receives as input the force of gravity.
2) Description of the Prior Art
There are numerous different types of motors. The function of any motor is to receive input energy and produce an output usually in the form of a rotational torque through an output shaft. The output shaft can then be used to operate a load, such as a pump to pump water, to turn a wheel, operate a generator to produce electricity, and so forth.
In the past, there have been many attempts at trying to design a motor which utilizes the force of gravity as the input energy. Such a motor would be highly advantageous as it would not require the burning of any fossil fuels or the addition of any other type of energy, such as solar energy, in order to operate the motor. Gravity is a force with a constant value on earth. If this force could be harnessed, such a motor could be proved to be most beneficial not requiring the addition of use of any specific input energy, other than gravity, eliminating the need to burn fossil fuels, create solar energy or use wind energy. A gravity motor would be very much like a wind machine or a machine that operates by solar energy in that all three would be using natural, readily available sources of energy.
In the past, the attempts at producing a gravity motor have proved to be unsuccessful for the reason that the energy losses incurred by the motor in order to operate the motor were greater than the energy created and there was not output torque produced. It is most important that when creating a gravity motor that the energy losses be maintained at a minimum. In essence, the motor unit of the motor has to be almost free wheeling utilizing only a tiny amount of energy in the operation of the motor. The gravity motors of the past have not been able to be constructed to be almost free wheeling in nature.
SUMMARY OF THE INVENTION
A gravity motor which has at least one motor unit which is constructed to include at least one motor member but generally will include a plurality of motor members. A slidable connecting rod is mounted relative to a rotatable output shaft and is low frictionally, movable thereto. At each end of the connecting rod is a weighted follower. The output shaft is low frictionally rotationally mounted relative to a housing. The housing also has mounted thereto a guide surface on a ramp with this guide surface being located from the six o'clock to the nine o'clock position within the plane of rotation of the motor unit. This guide surface is unsymmetrical relative to the axis of rotation of the output shaft. As a weighted follower comes into contact with the guide surface, that particular weighted follower is moved closer, by being pushed, to the output shaft with the weighted follower at the opposite end of the connecting rod being moved further away from the output shaft. The weighted follower that is moved further away is now located at the twelve o'clock position of the plane of rotation so that this weighted follower is subjected to the downward pull of gravity upon leaving the twelve o'clock position until almost at the six o'clock position, and since this weighted follower is located further from the output shaft than the weighted follower that is now being moved from the six o'clock position to the twelve o'clock position, there is a net downward rotational torque that causes the output shaft to rotate clockwise. This is the output of the output shaft. This gravity motor will operate continuously.
The primary objective of the present invention is to construct a motor that utilizes the force of gravity as the input energy to produce a rotational torque as an output.
Another objective of the present invention is to construct a motor which is composed of relatively few parts thereby minimizing the amount of energy that is required to operate the motor.
Another objective of the present invention is to construct a motor which can be manufactured relatively inexpensively and thereby sold to the ultimate consumer at a relatively inexpensive price.
