On March 25, 1902, Irving W. Colburn received U.S. Patent No. 696,008 on a Glass Working Machine:

Irving Wightman Colburn was born May 16, 1861, and died September 4, 1917. His first patent (U.S. Patent No. 620,642) for a “Glass Working Machine” that could make bottles issued March 7, 1899. His later ‘008 patent was for a process for the production of continuous flat glass disks which made the mass production for window panes possible. He formed the Colburn Machine Glass Co. in August 1906 but by 1911 he was bankrupt. Toledo Glass Company bought his patents in 1912, and Colburn worked with Toledo Glass to perfect the technology. Toledo Glass eventually became the Libbey-Owens Sheet Glass Company.
