  • Record player with spring-assisted pick-up arm return
    Patent number: 4453244
    Abstract: A record player having a pick-up arm which is automatically moved to the rest position by a spring, the energy necessary for returning the arm being stored by the lowering device of the arm. A rotating cam which lowers the arm also moves one end of an over-center spring-loaded lever, whose far end is guided such that before the arm is fully lowered the lever passes a dead center position. Motion past dead center causes a pin on the lever to move into position in which subsequent lever return, due to the loading spring, rotates the arm to the rest position.
