Tiffany's exhibit has been admired and patronized, but is not quite within my range of subjects. Darling, Brown & Sharpe have their machine-tools and gauges, Bliss & Williams their presses and dies. We have the Baxter, Snyder and Lovegrove portable engines, Taylor's and Aultman's agricultural engines.
For this we are mainly indebted to the almost creative power of modern machine-tools, and the facilities which they present for the production and reproduction of other machines. We also owe much to the mechanical agencies employed to drive them.
Thus it was from his desire to leave nothing to the chance of mere individual dexterity of hand that he introduced the slide rest in the lathe, and rendered it one of the most important of machine-tools. The first device of this kind was contrived by him for Bramah, in whose shops it continued in practical use long after he had begun business for himself. "I have seen the slide rest," says Mr.
At all events, he was so early and zealous a promoter of its use, that we think he may, in the eyes of all practical mechanics, stand as the parent of its introduction to the workshops of England. It is unquestionable that at the time when Maudslay began the improvement of machine-tools, the methods of working in wood and metals were exceedingly imperfect. Mr.
Now, everything is done by machine-tools with a degree of accuracy which the unaided hand could never accomplish. The automaton or self-acting machine-tool has within itself an almost creative power; in fact, so great are its powers of adaptation, that there is no operation of the human hand that it does not imitate." In a letter to the author, Mr.
Besides the invention of improved machine-tools for the manufacture of locks, Maudslay was of further service to Bramah in applying the expedient to his famous Hydraulic Press, without which it would probably have remained an impracticable though a highly ingenious machine.
These franks were to be sold by the porters of the convents, prisons, colleges, and other public institutions, at the price of one sou." Inaugural Address delivered before the Institution of Civil Engineers, 14th Jan. 1862. BEAMISH'S Memoir of Sir I. M. Brunel, 79, 80. There was the same clumsiness in all kinds of mill-work before the introduction of machine-tools.
With this object he aimed at the contrivance of improved machine-tools, which should be as much self-acting and self-regulating as possible; and it was while pursuing this study that he wrought out the important mechanical invention with which his name is usually identified that of the Slide Rest.
There was usually a considerable waste of steam, which the expedients of chewed paper and greased hat packed outside the piston were insufficient to remedy; and it was not until the invention of automatic machine-tools by the mechanical engineers about to be mentioned, that the manufacture of the steam-engine became a matter of comparative ease and certainty.
There he went on improving his old tools and inventing new ones, as the necessity for them arose, until the original slide-lathes used for making the block-machinery became thrown into the shade by the comparatively gigantic machine-tools of the modern school.
