Patent ID: 8186238

Claim:
A mechanical gear apparatus comprising: (A) a support base; (B) a drive gear, and, (C) a directional gear assembly comprising three gears, wherein the three gears are mounted on a common carrier, the common carrier consisting of two plates on each side of the directional gear assembly, the directional gear assembly comprised of said three gears, consisting of two directional gears and one driven gear, the common carrier being mounted on the support base by a first axle through each of the plates, the driven gear and the support base, whereby the directional gear assembly is partially rotatable around the first axle, the drive gear and the directional gear assembly operating on a common plane; the two directional gears including a first directional gear and a second directional gear mounted adjacent to each other in combination with said driven gear wherein at rest, or in motion, one of the directional gears is in driving engagement with the driven gear and the other directional gear is in driving engagement with the drive gear; the first and second directional gears having constant driving engagement with each other such that when the first directional gear is in driving engagement with the drive gear, the second directional gear is in driving engagement with the driven gear and when the second directional gear is in contact with the drive gear, the second directional gear is in driving contact with the driven gear, each said directional gear being rotatably mounted on a second and a third axle, respectively, the second and third axles being mounted through each plate of the common carrier; the driven gear always drivable in the same direction.
