This phonograph, manufactured by Admiral, featured a automatic changer .  Popular in the 1950’s, this player allowed you to stack about five records on the spindle at the  top of the changer.  As one song finished playing, the arm would raise, swing out of the way and allow the next record to drop.  The arm would move onto the next record and play that song.  After all records played the arm would swing back and the turntable would shut off.
