I want to drive a conveyor belt which will be feeding items from a hopper, however, I want to make a small mechanism which will, if the motor is switched on with it's output shaft spinning in the wrong direction, automatically turn the spin around to the right direction through a reversing gear arrangement. It has to do this without allowing spin in the wrong direction. I am hoping it can be as simple as a gear that gets driven around another gear until it starts going the right way. It should preferably not be sensor-driven, or reliant on external componets like switches. It should be as compact as possible. Anyone got any suggestions? Cheers ... Geoffrey Hyde

Not so very compact, but this arrangement does the job: (URL) (20 years ago, 1-Feb-05, to lugnet.technic)
