Abstract

A motivational generator which provides vibratory motions for screens, shakers, and vehicles which utilize such motions is described. In one embodiment rotatory motion is imparted to a spinning frame which transmits the motion to two unbalanced chevron-shaped vibratory devices via gears, belts, and pulleys. In another embodiment, the motion of the spinning frame is conveyed to unbalanced chevron-shaped vibratory devices directly through gears. In a third embodiment, the unbalanced chevron-shaped vibratory devices are rotated without rotation of the spinning frame. In the first two embodiments, the spinning frame imparts a gyroscopic effect which stabilizes the motivational generator against vibration in all directions other than the desired back-and-forth direction along the spin axis.

Claims

1. A motivational generator comprising a base, a rectangular frame having an inside and an outside fixedly mounted on the base, two unbalanced weights vibratory devices mounted on the rectangular frame, and means to rotate the unbalanced weights vibratory devices in synchrony wherein the means to rotate the unbalanced weights devices in synchrony comprise:

an axle rotatively mounted through the rectangular frame, a first miter gear mounted on the axle on the inside of the rectangular frame,

driven second and third miter gears rotatively mounted inside the rectangular frame which mesh with the first miter gear, and transmission means for transmitting the rotation of the second and third miter gears in synchrony to the unbalanced weights devices, and

means to rotate the axle.

2. A motivational generator comprising:

a base,

a rectangular frame having an inside and an outside rotatively mounted upon the base,

four unbalanced weights vibratory devices mounted on the rectangular frame,

means to rotate the unbalanced weights vibratory devices in synchrony, and

means to rotate the rectangular frame.

3. The motivational generator of claim 2 wherein the unbalanced weights vibratory devices are mounted on the inside of the rectangular frame, and

the unbalanced weights vibratory devices are chevron-shaped eccentric weights units.

4. The motivational generator of claim 2 wherein the unbalanced weights vibratory devices are mounted on the outside of the rectangular frame, and

the unbalanced weights vibratory devices are chevron-shaped eccentric weights units.

5. A motivational generator comprising:

a base,

a rectangular frame having an inside and an outside rotatively mounted upon the base,

two unbalanced weights vibratory devices mounted on the rectangular frame,

each said unbalanced weights vibratory device comprising an axle,

a hub attached to the axle having attachment means for two arms,

two arms attached to the hub asymmetrically, and

a weight attached to each arm,

forming a chevron-shaped eccentric weights unit,

means to rotate the unbalanced weights vibratory devices in synchrony, and

means to rotate the rectangular frame.

6. The motivational generator of claim 5 wherein the unbalanced weights vibratory devices are mounted on the inside of the rectangular frame.

7. The motivational generator of claim 5 wherein the unbalanced weights vibratory devices rotate in synchrony in opposite rotation.

8. A motivational generator comprising:

a base,

a rectangular frame having an inside and an outside rotatively mounted upon the base,

two unbalanced weights vibratory devices mounted on the rectangular frame,

means to rotate the unbalanced weights vibratory devices in synchrony comprising;

an axle which is fixedly mounted to the base and extends to the inside of the rectangular frame,

a first miter gear fixedly mounted on the axle inside the rectangular frame,

driven second and third miter gears rotatively mounted inside the rectangular frame which mesh with the first miter gear, and transmission means for transmitting the rotation of the driven second and third miter gears to the unbalanced weight devices, and

means to rotate the rectangular frame.

9. The motivational generator of claim 8 wherein the transmission means comprises a sleeve connecting a driven gear to a pulley, a pulley mounted on the unbalanced weights device, and linking means to connect the pulley on the sleeve to the pulley on the unbalanced weights device.

10. The motivational generator of claim 9 wherein the linking means is a belt.

11. The motivational generator of claim 8 wherein the transmission means comprises a sleeve with a driven miter gear mounted on a first end, said sleeve extending from the inside to the outside of the rectangular frame, and an unbalanced weights device mounted on a second end of the sleeve on the outside of the rectangular frame.
