Charles William Lancaster (1820–1878) 



In 1846 Lancaster constructed a model rifle, with which he experimented at Woolwich with marvellous success at a thousand and twelve hundred yards' (923 & 1100m) distance, and the Duke of Wellington then ordered some similar rifles for theRifle Brigade at the Cape of Good Hope. The years 1844 and 1845 he devoted to solving the problem of rifled cannon. In July 1846 he submitted to the board of ordnance a plan for using from rifled cannon smooth-sided conical projectiles, and imparting the necessary rotatory motion by driving a sabot on to the base of the projectile, the base having a V cross-piece cast in it. Further experiments, however, did not encourage him to go on with this scheme.

In 1850 he conceived the idea of the oval bore as the proper form for all rifled arms and cannon, and with this system his name will always be associated. In order to make his invention known, he constructed full-size working models of the 68-pounder, the largest gun then in the service, for the Great Exhibition of 1851. At the request of the government these models were not exhibited, but a 68-pounder oval-bore gun, made and rifled at Birmingham, with accurately turned shells, was sent to Shoeburyness for trial. The shooting of this gun directed attention to the oval-bore system, and in the succeeding experiments made at Woolwich Lancaster assisted the war department, and for some time superintended the production of the guns in the Royal Arsenal. In 1852 he experimented upon the .577 pattern Enfield rifled musket, and sent to the school of musketry at Hythe some specimens of carbines bored on his peculiar system. The device was considered satisfactory. In January 1855 the Lancaster carbine was adopted as the arm for the royal engineers, and was used by that corps until it was superseded by the Martini-Henry rifle in 1869. During the Crimean campaign oval-bored rifle cannon were used and did good service[citation needed], and were, it is said, the first rifled guns used in active service by the army and navy. Shortly after the war heavier guns were required for armour-piercing, and the experiments carried out at Shoeburyness, in which Lancaster assisted, led to a complete revolution in rifled artillery. For the oval-bore system of rifling he received substantial reward from the government. His transactions with the war office, however, led to disputes, and he scheduled his claims in a pamphlet, but was unsuccessful in obtaining that recognition of his services to which he considered himself entitled. Between 1850 and 1872 he took out upwards of twenty patents, chiefly in connection with firearms but including a joint patent with John Hughes for iron plating ships in 1860.[1] His last invention was a gas-check, applicable to large rifled projectiles.
