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.

A lifting apparatus for use with a phonograph having a tone arm provided with a stylus adapted to engage the sound groove in a record, said apparatus comprising:
- (a) a base member having a central cut-out portion including at least one key slot;
- (b) means for mounting said base member on said phonograph adjacent said record;
- (c) a boom arm having a member slidably mounted in said central cut-out portion so that one end of said arm extends inwardly of said phonograph to a position above the run-out groove of said record;
- (d) a magnet carried on said end of said arm;
- and
- (e) a magnetically attractive member mounted on said tone arm facing said magnet, said magnet exerting a force on said magnetically attractive member which lifts said tone arm after said stylus has moved past the end of the sound groove of said record.
