Robert Adams (handgun designer)

From Wikipedia, the free encyclopedia

Robert Adams (1809-1880) was a 19th-century British handgun designer and manufacturer who patented the first successful double-action revolver in 1851. His revolvers were used during the Crimean War, the Indian Mutiny, the U.S. Civil War, and the Anglo-Zulu War.

Robert Adams was the manager for the London house of arms manufacturers George & John Deane. On August 22, 1851, Robert Adams received a British patent for a new revolver design.

Adam's invention was a five-shot percussion (cap-and-ball) revolver with a spurless hammer and single piece barrel and frame. The revolver used a double-action only system in which the external hammer could not be cocked by thumbing it back, like most other pistols of the era, but instead cocked itself, the hammer falling upon the percussion-cap nipple each time the trigger was pulled. This made it possible to fire the gun much more rapidly than contemporary single-action revolvers, such as the Colt, which had to be cocked prior to each shot.

The weapon caused a sensation at the London International Exhibition of 1851, and orders for the revolver were great enough to prompt the Deane brothers to make Adams a partner in their firm, which became Messrs. Deane, Adams, and Deane.

Although highly-regarded, the hand-crafted Adams revolver was more expensive than Colt's mass-produced guns. It also lacked a recoil shield behind the cylinder, leaving the shooter's hand subject to powder burns resulting from "blowback" caused by the sometimes unpredictable black powder of the era. The lack of a hammer spur was also criticized since the longer trigger pull of the Adams made it less accurate than the Colt. Furthermore the Adams' nipples, upon which the percussion caps were set, were unhardened and sometimes burst upon firing. An "Improved Frame" model was offered in 1854, presenting both a sleeker look and more comfortable grip.

In 1854 the British Board of Ordnance reviewed the Adams together with other percussion revolvers with a view to adopting one as an official service sidearm. Concerns about the gas escape between the cylinder and barrel during discharge resulted in no decision being made. Nevertheless British officers purchased the Adams privately and the gun proved its worth in battle during the Crimean War.

In 1855 a veteran of the Crimean conflict, Lieutenant Frederick Beaumont, improved the gun by linking the trigger to a spurred hammer, permitting both single- and double-action fire. A new version of the revolver, the Beaumont-Adams, was produced and became so popular that it is said that as a result Samuel Colt was forced to shut down his London manufactory.

Adams had a falling out with the Deane brothers the following year and founded a new arms concern, the London Armoury Company, on February 9, 1856. Another important stockholder was Adams' cousin, James Kerr, who later invented the Kerrs Patent Revolver. The factory was established on the former site of the South-Eastern Railway Company in the Bermondsey section of London.

The Indian Mutiny of 1857 established the Adams as the official revolver of the British Army. In the bitter fighting it was found that rapid fire was more important than accuracy, and the man-stopping power of the Adams' large caliber bullet was also valued.

Several variations and improvements were made upon the Adams, which was manufactured in Europe and briefly in the United States under license. The majority of British-made Adams guns seem to have been in 54 bore, approximately .44 caliber, but several smaller and at least one larger bore were also offered. In 1857 the U.S. government purchased 100 revolvers in .36 caliber and another 500 from the Adams-licensed Massachusetts Arms Company. The 100 British-made guns were issued to the U.S. Army with the rest held in storage until issued at the outbreak of the U.S. Civil War. In addition Adams revolvers were purchased from the London Armoury prior to and during the war by individual states and the U.S. and Confederate governments.

The London Armoury Company flourished due to the manufacture of the Adams revolver, however, in 1859 the company's board of directors decided to increase the production of infantry rifles, decreasing revolver production. Adams disagreed with the decision, selling his stock and leaving the company. Kerr then became the armoury's dominant figure and his revolver, together with a large number of rifles, were sold to the Confederate government which became the armoury's principal client. With the fall of the Confederacy the fortunes of the company declined and it went into receivership in 1866.

Adams owned the rights to his revolver, which the London Armoury Company had only produced under license, and he now manufactured them in Birmingham, with minor improvements keeping his revolvers in competition with other designs. Robert Adams died in 1880, but a relation, John Adams, of the Adams Patent Small Arms Manufacturing Company, briefly produced an excellent percussion revolver (Adams model of 1866), before introducing a six-shot, double-action cartridge pistol, firing the .450 Boxer round. This latter pistol was manufactured in three distinct variations (differences related mainly to methods of spent cartridge ejection) between 1867 and about 1880. The models were tested and adopted by the British army and navy, with the last, the M1872 Mark III, seeing the widest use. The John Adams revolver remained the official sidearm of the British army until replaced by the Enfield Mark I in 1880. See Chamberlain and Taylerson, Adams' Revolvers (London, 1976)
