Latimer received a patent for The "Process of Manufacturing Carbons"
Time: Tuesday Jan 17, 1882
Place: New York, U.S.
Details: Lewis Latimer, employed at the time by Edison, developed an improved method of heat-treating carbon filaments which reduced breakage and allowed them to be molded into novel shapes, such as the characteristic "M" shape of Maxim filaments. On 17 January 1882, Latimer received a patent for the "Process of Manufacturing Carbons", an improved method for the production of light bulb filaments, which was purchased by the United States Electric Light Company. Latimer patented other improvements such as a better way of attaching filaments to their wire supports.
Best-effort ordering. Some events may appear out of order since many are only known to the year, but they are usually around the same period.
