ARMSTRONG, See also:WILLIAM See also:GEORGE ARMSTRONG, See also:BARON (1810—1900) , See also:British inventor, founder of the See also:Elswick manufacturing See also:works, was See also:born on the 26th of See also:November 1810, at See also:Newcastle-on-See also:Tyne, and was educated at a school in See also:Bishop See also:Auckland. The profession which he adopted was that of a See also:solicitor, and from 1833 to 1847 he was engaged in active practice in Newcastle as a member of the See also:firm of See also:Donkin, See also:Stable & Armstrong. His sympathies, however, were always with See also:mechanical and scientific pursuits, and several of his inventions date from a See also:time anterior to his final See also:abandonment of the See also:law. In 1841—1843 he published several papers on the See also:electricity of effluent See also:steam. This subject he was led to study by the experience of a colliery engineman, who noticed that he received a See also:sharp See also:shock on exposing one See also:hand to a See also:jet of steam issuing from a See also:boiler with which his other hand was in contact, and the inquiry was followed by the invention of the " hydro-electric " See also:machine, a powerful generator of electricity, which was thought worthy of careful investigation by See also:Faraday. The question of the utilization of See also:water-See also:power had engaged his See also:attention even earlier, and in 1839 he invented an improved rotary water motor. Soon afterwards he designed a See also:hydraulic See also:crane, which contained the germ of all the hydraulic machinery for which he and Elswick were subsequently to become famous. This machine depended simply on the pressure of water acting directly in a See also:cylinder on a See also:piston, which was connected with suitable multiplying See also:gear. Ln the first example, which was erected on the See also:quay at Newcastle in 1846, the necessary pressure was obtained from the See also:ordinary water mains of the See also:town; but the merits and advantages of the See also:device soon became widely appreciated, and a demand arose for the erection of See also:cranes in positions where the pressure afforded by the mains was insufficient. Of course pressure could always be obtained by the aid of See also:special reservoirs, but to build these was not always desirable, or even practicable. Hence, when in 185o a hydraulic See also:installation was required for a new See also:ferry station at New See also:Holland, on the See also:Humber See also:estuary, the See also:absence of water mains of any See also:kind, coupled with the prohibitive cost of a special See also:reservoir owing to the See also:character of the See also:soil, impelled him to invent a fresh piece of apparatus, the " See also:accumulator," which consists of a large cylinder containing a piston that can be loaded to give any desired pressure, the water being pumped in below it by a steam-See also:engine or other See also:prime mover. This See also:simple device may be looked upon as the See also:crown of the hydraulic See also:system, since by its various modifications the installation of hydraulic power became possible in almost any situation.

In particular, it was rendered practicable on See also:

board See also:ship, and its application to the manipulation of heavy See also:naval guns and other purposes on warships was not the least important of Armstrong's achievements. The Elswick works were originally founded for the manufacture of this hydraulic machinery, but it was not See also:long before they became the birthplace of a revolution in gunmaking; indeed, could nothing more be placed to Armstrong's See also:credit than their See also:establishment, his name would still be worthy of remembrance. See also:Modern See also:artillery See also:dates from about 1855, when Armstrong's first See also:gun made its See also:appearance. This weapon embodied all the essential features which distinguish the See also:ordnance of to-See also:day from the See also:cannon of the See also:middle ages—it was built up of rings of See also:metal shrunk upon an inner See also:steel See also:barrel; it was loaded at the See also:breech; it was rifled; and it threw, not a See also:round See also:ball, but an elongated projectile with ogival See also:head. The guns constructed on this principle yielded such excellent results, both in range and accuracy, that they were adopted by the British See also:government in 1859, Armstrong himself being appointed engineer of rifled ordnance and receiving the See also:honour of See also:knighthood. At the same time the Elswick Ordnance See also:Company was formed to manufacture the guns under the supervision of Armstrong, who, however, had no See also:financial See also:interest in the concern; it was merged in the Elswick See also:Engineering Works four years later. See also:Great See also:Britain thus originated a principle of gun construction which has since been universally followed, and obtained an armament See also:superior to that possessed by any other See also:country at that time. But while there was no doubt as to the See also:shooting capacities of these guns, defects in the breech mechanism soon became equally patent, and in a few years caused a reversion to muzzle-loading. Armstrong resigned his position in 1863, and for seventeen years the government adhered to the older method of loading, in spite of the improvements which experiment and See also:research at Elswick and elsewhere had during that See also:period produced in the mechanism and performance of heavy guns. But at last Armstrong's results could no longer be ignored; and See also:wire-See also:wound breech-loading guns were received back into the service in 1880. The use of steel wire for the construction of guns was one of Armstrong's See also:early ideas. He perceived that to coil many turns of thin wire round an inner barrel was a logical See also:extension of the large hooped method already mentioned, and in See also:conjunction with I.

K. See also:

Brunel, was preparing to put the See also:plan to See also:practical test when the See also:discovery that it had already been patented caused him to abandon his intention, until about 1877. This incident well illustrates the ground of his objection to the British system of patent law, which he looked upon as calculated to strifle invention and impede progress; the patentees in this See also:case didnot See also:manage to make a practical success of their invention themselves, but the existence of See also:prior See also:patents was sufficient to turn him aside from,a path which conducted him to valuable results when afterwards, owing to the expiry of those patents, he was See also:free to pursue it as he pleased. See also:Lord Armstrong, who was raised to the See also:peerage in 1887, was the author of A Visit to See also:Egypt (1873), and Electric See also:Movement in See also:Air and Water (1897), besides many professional papers. He died on the 27th of See also:December 1900, at Rothbury, See also:Northumberland. His See also:title became See also:extinct, but his See also:grand-See also:nephew and See also:heir, W. H. A. F. See also:Watson-Armstrong (b.. 1863), was in 1903 created Baron Armstrong of See also:Bamburgh and Cragside.
