ABSTRACT:
A safety clutch which has a steel ball which is adapted to move from half in a hemispherical recess in its drive plate and half in a cylindrical hole in its driven plate to a position completely in the cylindrical hole. A conveyor conducts milk or like cartons to a point where caps are ultrasonically welded to the inside of the foldable tops of the cartons. The safety clutch discontinues power in the event of an overload.
