Bi-powered clutchless variable speed transmission

When motor 1 is powered up and running the primary shaft is connected to the Planetary Gear assembly B, while motor 2 is not running. The output shaft out of Planetary Gear assembly A is zero. As power goes through Planetary Gear assembly B and transfers the power through the bevel gear and then the worm gear on Planetary gear assembly A, which then rotates the ring gear at the appropriate speed to cause the Planetary Gears to remain stationary about the sun gear. Consequently no power is transferred to the output shaft. When motor 2 is powered up, and as its speed increases it starts the rotation of the ring gear on Planetary Gear assembly B and causes the output shaft to reduce its speed and in turn this change in speed is transferred to the ring gear on Planetary Gear assembly A which now starts the rotation of the output shaft of assembly A.
