Control devices for pick-up arms of record players

A control device for a pick-up arm of a record player, said device comprising:

• a. a power take-off element (2) disposed on a vertical spindle of a pick-up arm;
• b. a shaft of rotation;
• c. a sun wheel mounted on said shaft for rotation therewith;
• d. drive means for rotating said sun wheel;
• e. a rotatable support means consisting of an element and a bar non-rotatably connected to each other with said bar being mounted on said shaft and rotatable independently thereof;
• f. a clutch mounted on said shaft and connecting said element to said shaft to rotation therewith and thereby serving to rotate said bar with said element;
• g. at least one planet wheel means in engagement with said sun wheel (11) and mounted to said rotatable support means about said shaft of rotation whereby, on rotation of said sun wheel (11), said rotatable support means with said planet wheel means mounted thereon will also rotate until said planet wheel means is brought into contact with said power take-off element (2) whereupon said clutch (12) will slip and said planet wheel means will rotate about its said axis of rotation and, through frictional contact with said power take-off element (2), will rotate said vertical spindle and thus swivel said pick-up arm;
• and
• h. lifting means responsive to said rotation of said rotatable support means to raise said pick-up arm before said planet wheel means is brought into contact with said power take-off element.
