Welding welding was invented in 1893, and around that time another process, oxyfuel welding, became well established. Acetylene was discovered in 1836 by Edmund Davy, but its use was not practical in welding until about 1900, when a suitable torch was developed. At first, oxyfuel welding was one of the more popular welding methods due to its portability and relatively low cost. As the 20th century progressed, however, it fell out of favor for industrial applications. It was largely replaced with arc welding, as advances in metal coverings (known as flux) were made. Flux covering the electrode primarily shields the base
Colt Acetylene Flash Lantern Colt Acetylene Flash Lantern The Colt Acetylene Flash Lantern (or Colt Field Signal Lamp) was a acetylene signal lamp produced by the J. B. Colt Company and used by the United States military at the start of the 1900s. A patent for the device was filed in 1902. A description from maneuvers at Fort Riley detailed the device: The Colt's acetylene flash lantern was employed for night signals. The flash is produced by means of a key which causes a full flame to burst forth in the lantern for the length of time the key is pressed down; when the
