ABSTRACT:
A device for automatically lifting a phonograph stylus from a record after the end of the sound groove has been played includes a pedestal base mounted on a support plate adjacent the turntable and provided with a cavity adapted to receive one end of a boom arm, the free end of which extends to a position over the record run-out groove. The vertical distance between the free end of the boom arm and the record can be adjusted by means of a setscrew. After the stylus has passed the end of the sound groove and entered the run-out groove, a small, thin metal disk located on the top surface of the stylus cartridge receiving shell is attracted to a magnet mounted on the lower surface of the free end of the boom arm and lifts the stylus off of the record.
