gravity device
Kind Code:

The frame structure contains a main shaft, which turns a rotor hence turning four main bearings by using the force of gravity. On the lower section of the frame there is a ball limiting guide which is located on the right side of the main shaft. The distance is far enough away so that steel balls can rotate freely. When the steel ball positions are located on the longest positions of the arms, away from steel ball positions on the shortest positions of the arms gravity forces steel ball positions towards Body Dead Centre. At this time a circular motion is created around the main shaft thus increasing power from gravity.

What is claimed is:

1. A mechanism that utilizes gravity as its only source of power. The mechanism works on the principal of converting positive and negative gravity forces.

2. The arm has a 30-degree flexibility movement to facilitate faster gravity engagement (FIG. 3B).

3. The arm extends as the ball rolls down the limiting guide therefore increasing the gravity force (FIG. 4).

4. The end of the arm has an absorbing mechanism thereby reducing the friction forces as the ball hits the limiting ball guide (FIG. 4).

5. The arm will retract as the ball is carried back up to Position A. This will decrease the amount of gravity forces.


Gravity forces a downward and circular motion on a series of rotating arms with attached balls that rotate on a fixed axis.

1. The machine's primary source of power is obtained from the force of gravity in order for it to work. Gravity forces a downward and circular motion.

2. On the frame structure (FIG. 2 Part #1) contains a main shaft (FIG. 3 Part #2) which turns the rotor (FIG. 3 Part #3) hence turning four main bearings (FIG. 3 Part #4).

3. The bearing shaft (FIG. 3 Part #5 ) is a free turning roller guide FIG. 3 Part #6) where a sliding ball carrier (FIG. 3 Part #7) can increase its movement up to 30° (see FIG. 3B).

4. The sliding ball carrier (FIG. 3 Part #7) contains a shaft (FIG. 3 Part #8), which turns steel ball (FIG. 3 Part #9) freely.

5. On the lower section of the frame structure (FIG. 2 Part #1) there is a ball limiting guide (FIG. 2 Part #10) which is located on the right side of the main shaft (FIG. 3 Part #2). The distance is far enough away so that the steel balls can rotate freely.

6. In the upper part of the frame structure (FIG. 2 Part #1) Position A is top dead centre (TDC). On the lower part of the frame structure (FIG. 2 Part #1) Position B shows bottom dead centre (BDC).

7. In the horizontal position of the main shaft (FIG. 2 Part #2) to the left side is Position C, which depicts the longest length of the arm. To the right side is Position D, which depicts the shortest length of the arm (FIG. 2 Part #2).

8. When steel ball positions (FIG. 1 Part #9) 11, 13, and 15 are located on the longest position of the arm, away from steel ball positions 17, 12, 14, 16 and 18 gravity forces steel ball positions 11, 13, and 15 towards Position B (BDC). At this time a circular motion is created around the main shaft (FIG. 3 Part #2).

9. When steel ball position 17 passes Position B (BDC), the force of gravity opens its movement by 30°, which allows it to move easier on ball limiting guide (FIG. 2 Part #10). Because of the contact to the ball-limiting guide (FIG. 2 Part #10) the steel balls start to rotate around shaft (FIG. 3 Part #8).

10. When steel ball position 18 passes Position A (TDC) the force of gravity returns it back to its natural state (normal position). This event takes place when the rest of the steel balls go through a circular motion.

11. Due to the fact that the ball limiting guide (FIG. 2 Part #10) is positioned in such a way, steel ball position 17 and 12 shorten the distance of the arm at Position D ((Lever Arm Shorter), which in turn the opposite side on the arm lengthens at Position C (Lever Arm Longer).

12. Increasing the length of the ball-limiting guide (FIG. 2 Part #10) over the shaft (FIG. 3 Part #8) provides the power source for the gravity motor to work efficiently.

  • Part 1 Frame Structure
  • Part 2 Main Shaft
  • Part 3 Rotor
  • Part 4 Main Bearing
  • Part 5 Bearing Shaft
  • Part 6 Roller Guide
  • Part 7 Sliding Ball Carrier
  • Part 8 Shaft
  • Part 9 Steel Ball
  • Part 10 Ball Limiting Guide
  • 11-18 Ball positions
  • Part 20 Pulley
  • Position A Top Dead Centre (TDC)
  • Position B Bottom Dean Centre (BDC)
  • Position C Lever Arm (Longer)
  • Position D Lever Arm (Shorter
    Lowering the Resistance

1. In the construction of the motor there is a additional arm installed (FIG. 4A Part #1) which freely moves on the shaft (FIG. 4A Part #6). On one end of the arm there is a counterweight (FIG. 4A Part #2) to control its balance. On the opposite end of the arm is location for the ball carrier (FIG. 4A Part #3) on which the ball slides (Phase #1) and goes into Phase #2 and Phase #3 as shown in FIG. 4.

When the arm travels towards Position D (FIG. 4) it comes to the ball-limiting guide, where the ball easily moves into position 5. At this time (ball position 1), gravity force moves the arm back to Position B and receives the next ball. To see how this works it is shown in FIG. 4.

FIG. 6 demonstrates a second way to reduce resistance. The main ball carrier (Position D) on its center rotates over the shaft (Part #8). On the ends of the ball carrier (Part #4) there are shafts (Part #5) which freely rotate the carrier with secured ball (Part #1). On the end (Part #3) there is a connecting rod with enlarged holes (Part #6) which connects two balls (Part #3). The connecting rod is secured with a nut on which roller (Part #2) rotates on ball limiting guide (Part #7) upwards into Phase I, lifting the ball into Phase II and gravity moves opposite ball towards the center and at this time the arm is shorter, while the ball makes the other side longer (Phase III). By relocating the position of the connecting rod (Part #3) away from the center the resistance is lowered Part #5). This way depicts lowering the resistance in contrast as using the ball limiting guide.

Increasing the Torque

FIG. 7A demonstrates how the arm extends after it passes the 90° angle and is pulled by the gravity.

FIG. 7B demonstrates the completed movement of the arm with the ball moving from negative to neutral and into positive force.

Gravity motor works on the principle of extending the arm and thereby increasing the amount of gravity torque (FIG. 7A and 7B). FIG. 7 shows how to make the arm longer with more force on ball carrier (Position A.). Ball Position A has two shafts with rollers on them (Part #3 and #4). In the middle of the rollers is a moving off-set arm (Part #2) on which is mounted ball B (FIG. 7B Part #5) going through (FIG. 7A Part #7).

During the rotation (FIG. 7B Part #1) the ball passes 90° gravity force moving it downwards with ball Position A with the mechanism on which is located ball Position B. That is Phase I and Phase II is when ball Position A closes the angle of 180°, at the same time ball Position B moves over 90° and gravity force pulls it down and the mechanism makes the arm longer (Phase III).

FIG. 8 demonstrates another way how to lengthen the arm and obtain more torque.

When the 30° angle starts to close (FIG. 8A Part #1 )over to Position 1 which freely travels to Position 2 (Phase II). With further rotation (Position 1) passes the 180° angle the mechanism works in a way that through (Position 3) during the gravity force (Position 4) slides until it stops on (Position 7) and that is in Phase III.

FIGS. 8 and 8A depict the mechanism, which makes the arm longer using the force of gravity and activating more force.

Gravity force pulls the ball (FIG. 8 Position 1), which freely travels to Position 2. When ball in Position 1 passes neutral gravity to Position 2 the force extends the arm extension thus increasing gravity torque (Position 3). When the ball reaches the limiting guide the arm retracts and thereby decreases the gravity force of the mechanism (FIG. 1).
