His design patents are for phonograph cabinets and light bulbs with substantial decorative features. – Design for an Incandescent Electric Lamp – Design for Incandescing Electric Lamp – Design for a Phonograph-Cabinet – Design for a Cabinet – Design for a Grille for Phonograph Cabinets – Design for a Grille for Phonograph Cabinets – Design for a Phonograph Cabinet – Design for a Phonograph Cabinet – Design for a Phonograph Cabinet Improvements Lewis Latimer patented an improved method of producing the filament in light bulbs (there is no evidence that this was ever used by an Edison company) Emile Berliner developed the gramophone, which is essentially an improved phonograph, with the main difference being the use of flat records with spiral grooves. Edward H. Johnson had light bulbs specially made, hand-wired, and displayed at his home on Fifth Avenue in New York City on the first electrically-illuminated Christmas tree on December 22, 1882.
