Alley & MacLellan Ltd was a mechanical engineering company based in Glasgow, Scotland. Its products were sold under the Sentinel brand. ==History== Alley & MacLellan was founded in Bridgeton, Glasgow, Scotland in 1875 by Stephen Alley and John Maclellan. The company began by building valves, compressors and other parts for steamships.〔("Sentinel Waggon Works", ) ''Discover Britain''.〕 By 1880 the company had moved to larger premises in Polmadie, and began building complete ships.〔 Because of the factory location far from the ocean, the ships were designed so that they could be transported in sections and assembled at dockside.〔("Alley and MacLellan" ). ''Captains of Industry'' by William S. Murphy. Published 1901. Reprinted in ''Gracie's Guide to Industrial History''.〕 In 1883, the company designed a new type of high speed steam engine which was used to generate electricity on board ships. The company was incorporated in 1903 as Alley & MacLellan Ltd. with Stephen Alley becoming a partner after his father's death.〔 Their factory in Polmadie was called Sentinel Works.〔(Administrative summary accompanying "Records of Alley & MacLellan (Polmadie) Ltd, engineers, Polmadie, Glasgow, Scotland" ), University of Glasgos〕 That year the company acquired Simpson and Bibby of Horsehay, a manufacturer of steam powered road vehicles,〔 and by 1905 it was manufacturing steam wagons. In about 1907 the company began building dump trucks; The company continued to manufacture steamships and boats, and in 1912 its output was about 2700 tons. Eventually almost 500 small ships and boats were produced. The vast majority of these vessels were assembled at the Jessie Street works using nuts and bolts, then dismantled and shipped as parts in crates to their client destination where they were re-assembled using rivets. At least one Alley & McLellan ship is still in existence - the motor vessel (originally steam ship) Chauncy Maples on Lake Nyasa (Lake Malawi). in 1915 the wagon and truck aspect of the business had grown to the point that the company opened a subsidiary company in Shrewsbury as the Sentinel Waggon Works, manufacturing lorries and railway vehicles.〔 A group of the core Scottish staff moved from Glasgow to Shrewsbury. In 1918 the company was acquired by William Beardsmore & Co., Ltd,〔 and opened another subsidiary, The Sentinel Valve Works, in Worcester, England, to expand its manufacture of valves. Both factory buildings were prefabricated in Glasgow, and reassembled on site,〔(【引用サイトリンク】url=http://cheshire.cent.gla.ac.uk/ead/search?operation=search&fieldidx1=bath.corporateName&fieldrel1=exact&fieldcont1=alley%20%26%20maclellan )〕 again a group of core Scottish staff moved to Worcester from Glasgow. One unusual feature of the age was that both the Shrewsbury and Worcester 〔http://www.britainfromabove.org.uk/image/epw005417?gazetteer=Worcester&ADMIN_AREA=Worcester&ref=82〕 factory buildings were prefabricated in Glasgow prior to local assembly. The company manufactured a variety of compressors, including ones used in foghorns. By 1937, Alley & MacLellan was once more an independent company. In 1945 it became a subsidiary of Glenfield & Kennedy Ltd.〔 Alley & McLellan continued to operate in the original Sentinel Works in Jessie Street, Glasgow until the 1950s, producing various engineering products. The 'Sentinel' name continued to be used for the products of the original Glasgow works until the mid 20th Century. In 1975 the company was dissolved. The original Sentinel Works in Jessie Street, Glasgow was still in existence in 2009 though now in a very derelict condition. The design offices and pattern shop is listed category A as a building of significant national importance. It was the first steel reinforced concrete building in Scotland. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alley & MacLellan Ltd」の詳細全文を読む スポンサード リンク
