Excerpt from Press-Working of Metals: A Treatise Upon the Principles and Practice of Shaping Metals in Dies by the Action of Presses, Together With a Description of the Construction of Such Implements in Their Various Forms, and of the Materials Worked in Them
Did there already exist an extensive literature upon the subject treated of in these pages, their somewhat meager information might in some cases prove superfluous. Failing, however, to find upon record many of the facts and principles which seem necessary to the successful design, construction, and operation of presses and dies, I have drawn upon a personal experience of many years in this line of work, and prepared a treatise which, as far as it goes, may perhaps be of value to the makers and users of the interesting class of tools which serve as its subject-matter. The use of these tools is very rapidly increasing in recent years, an almost marvelous variety of articles now being pressed out of sheet- or bar-metals which a few years ago were hand-forged or cast, or were non-existent.
Such cut, pressed, stamped, and drawn articles are found in all departments of our modern civilized life, often forming integral parts even of the cradle and the coffin - not to speak of the wedding-ring between. The system by which they are manufactured appears as a large factor in the creation of civilization itself, by making possible the cheap and uniform production of much of our hardware, our cooking utensils, and plate, and jewelry; our timepieces, and sewing-machines, and typewriters; our reapers, and wagons, and bicycles - to say nothing of the numberless other tools pertaining to our complex life, from a button even to a steamship.
