Elisha King Root, born May 5, 1808, died September 1, 1865. In his young age he worked in a cotton mill and switched, at age of 15, to work in a machine shop in Ware, Massachusetts. So about 1832 he was hired by Samuel W. Collins to work in his axe factory Collins Company, Collinsville. The company profited by Roots management and inventive skills. He introduced efficient manufacturing processes and developed new machines for edge-tool production. In 1849 Colt offered him the position of superintendent at a higher salary than he was paied by the Collins Company. Root moved to Hartford and designed and built the new armory. For Colt's Petent Firearms Manufacturing Company he designed drop hammers for forging and machines for firearms manufacturing processes. Root's patent does not cover the mechanism of the Colt Root revolver. That revolver was patented by Samuel Colt. E.K. Root acting only as one of the witnesses. He was the superintendent of the Colt factory in Hartford from 1849 to 1862. On the death of Colt in January, 1862, Root succeeded to the presidency of Colt's Patent Firearms Mfg. Co., a position he held until his death in 1865. A certain number of experimental revolvers were made under his patent 13,999 but not real production has been made.
