Machinery
"The Prince Consorts were all three engined by Maudslay and Sons on an identical plan, … the arrangement of their machinery was very unusual, though not entirely without precedent in wooden-hulled steamers. When horizontal reciprocating marine engines were being installed it was necessary as a first step to select a position for the cylinders with enough athwartship level to give a proper length for the stroke… As the Prince Consorts had been shaped with an underwater run of the old style before being ordered for conversion… their floors rose considerably abaft the midship point; which meant the only practicable position for the much larger engines they were to carry was in the added central body halfway between bow and stern." (Iron-hulled ironclads had their engines further aft.) "Return-connecting-rod engines were installed."
Royal Oak's boilers were in one group of six on the forward side of the engines. The Prince Consorts' larger engines required more boilers, so they had two groups of four; one set forward of the engines, and one set further aft; this was why the Prince Consorts had two widely spaced funnels (one for each set of boilers). The Prince Consort's boilers were not of equal size. The forward set were larger and had five furnaces each, whereas the aft boilers had three furnaces each. "Each group of boilers had its own coal bunkers abreast it". "The boilers worked at 20 lb pressure."

Famous quotes containing the word machinery:
“There has been something crude and heartless and unfeeling in our haste to succeed and be great. Our thought has been “Let every man look out for himself, let every generation look out for itself,” while we reared giant machinery which made it impossible that any but those who stood at the levers of control should have any chance to look out for themselves.”
—Woodrow Wilson (1856–1924)
“We saw the machinery where murderers are now executed. Seven have been executed. The plan is better than the old one. It is quietly done. Only a few, at the most about thirty or forty, can witness [an execution]. It excites nobody outside of the list permitted to attend. I think the time for capital punishment has passed. I would abolish it. But while it lasts this is the best mode.”
—Rutherford Birchard Hayes (1822–1893)
“Totalitarianism is never content to rule by external means, namely, through the state and a machinery of violence; thanks to its peculiar ideology and the role assigned to it in this apparatus of coercion, totalitarianism has discovered a means of dominating and terrorizing human beings from within.”
—Hannah Arendt (1906–1975)
