Gas burner patent

In 1899, a gas burner was patented by Benjamin F. Jackson, a black American inventor (No. 622,482). His design improved the equal distribution of air under pressure to ensure more complete combusion of the fuel gas. He assigned the patent to Robert Hoe, Theodore Mead and Charles Carpenter of New York City. The previous year, he took out patents on a "Heating Apparatus" and a "Matrix Drying Apparatus."[Image: gas burner vertical section and plan views]
