53 페이지 - The hand that rounded Peter's dome, And groined the aisles of Christian Rome, Wrought in a sad sincerity: Himself from God he could not free; He builded better than he knew : The conscious stone to beauty grew.
119 페이지 - The Permanent Way and Coal-burning Locomotive Boilers of European Railways, with a Comparison of the Working Economy of European and American Lines, and the principles upon which Improvement must Proceed.
59 페이지 - TO HONOUR THOSE WHO BEST DESERVE THEIR GRATITUDE, THE KING HIS MINISTERS, AND MANY OF THE NOBLES AND COMMONERS OF THE REALM RAISED THIS MONUMENT TO JAMES WATT, WHO DIRECTING THE FORCE OF AN ORIGINAL GENIUS, EARLY EXERCISED IN...
132 페이지 - ... the result of his thought gave us the present accepted type of American Bessemer plant. He did away with the English deep pit and raised the vessels so as to get working space under them on the ground floor; he substituted top-supported hydraulic cranes for the more expensive counter-weighted English ones, and put three ingot cranes around the pit instead of two, and thereby obtained greater area of power. He changed the location of the vessels as related to the pit and melting-house.
132 페이지 - He modified the ladle crane, and worked all the cranes and the vessels from a single point; he substituted cupolas for reverberatory furnaces, and last, but by no means least, introduced the intermediate or accumulating ladle which is placed on scales, and thus insures accuracy of operation by rendering possible the weighing of each charge of melted iron, before pouring it into the converter. These points cover the radical features of his innovations. After building such a plant, he began to meet...
64 페이지 - The Inadequate Union of Engineering Science and Art," in which he thus describes the relation of the •driver to his engine: "The thoughtful locomotive driver is clothed upon, not with the mere machinery of a larger organism, but with all the attributes except volition of a power superior to his own. Every faculty is stimulated, and every sense exalted. An unusual sound amid the roaring exhaust and the clattering wheels, tells him instantly the place and degree of danger as would a pain in his own...
208 페이지 - The consciousness of a certain jarring of the foot-plate, a chattering of a valve-stem, a halt in the exhaust, a peculiar smell of burning, a sudden pounding of the piston, an ominous wheeze of the blast, a hissing of a water-gauge — warning him respectively of a broken spring-hanger, a cutting valve, a slipped eccentric, a hot journal, the priming of the boiler, high water, low water, or failing steam — these sensations, as it were, of his outer body, become so intermingled with the sensations...
215 페이지 - ... managers of engineering enterprises, that it is not a matter of favor, but a matter of as much interest to themselves as to any class, that young men of suitable ability and of suitable preliminary culture, however acquired, should have opportunity and encouragement to master the practical features of technical education in works, not as mere apprentices, but under reasonable facilities for economy of time and completeness of research. But these conditions do not largely exist, and are only growing...
213 페이지 - ... knowledge, which is the normal condition of those who range only within the sphere of their own practice, and to whom analysis and generalization, in their business affairs, as well as in morals and politics, are an unknown thing. It is unfortunately true that a large number of managers in metallurgical enterprises — men who are deemed indispensable, and who probably, are indispensable, in the average state of practical science, are thus not incorrectly characterized. Conscious of their power...
207 페이지 - ... call a chemical art, to a high degree of commercial success, and this in the absence of any metallurgical change or chemical improvement whatever, in the treatment of the metal. During all this time, there was almost no literature of the Bessemer manufacture, and no instructor save that grim sphinx the converter and the well-nigh inscrutable process. It was a hand-tohand fight, involving mechanical details, refractory linings, celerity of operations, regularity of melting and conversion and economy...
