Descriptions:
Roller clutch
The blue roller is driving The orange one is driven. The two small rollers are idle. Using the pink arm to stop or reverse the orange roller’s rotation. The mechanism’s weakness is needed measures to create pressure at the contact places of the blue, green and yellow rollers (not shown).
4-Gear clutch
The blue gear is driving. The orange one is driven. The two small gears are idle. Using the pink arm to stop or reverse the orange gear’s rotation. Measure for fixing the pink arm at its three working positions is not shown.
The mechanism’s weakness is the possible collision of the orange gear and the two small gears.
Gear and Roller clutch
The blue gear is driving. The orange roller is driven.
The two gear and roller combinations are idle. Using the pink arm to stop or reverse the orange gear’s rotation.
The mechanism does not have the weaknesses shown in 4-roller clutch or in 4-gear clutch:
Reverse mechanism 1
Violet lever has 3 positions: forward, neutral and backward. Ball spring device for the lever positioning is not shown. Green and blue gears are in permanent mesh. When left pink gear is in mesh with the blue gear, grey slider goes forward. When right pink gear is in mesh with the green gear, grey slider goes backward.
The lever neutral position is for stopping the grey slider or setting its position (by hand turning orange screw).
The mechanism is suitable for slow speed. In case of fast speed to stop the input before reversing.
