Elements Of Machine Construction And Drawing PDF Download

Excerpt from Elements of Machine Construction and Drawing: Or, Machine Drawing, With Some Elements of Descriptive and Rational Cinematics This book may be compared to an excursion train. Everything mechanical has called, or striven for a place in it, if only to cling to the platform of briefest mention. Yet not a tithe even of the beauties of mechanism have been admitted, for want of room. Indeed, one of the most arduous labors connected with the composition of this work has been to keep out the nearly irrepressible crowd of topics and examples that were pressing into it. Those that have been admitted have been selected with great care, after personal inspection in machine shops, and from valuable circulars, correspondence, and published authorities. Other examples have been partially represented by woodcuts and brief notices, or have necessarily been excluded, and remanded back to the great world of mechanism. In either case the governing idea has been, to develope the comprehensive scheme of the General Table proportionately, though briefly, with examples that should be American (mostly), new, and good. There are at least six topics in this work, about which the troublesome problem has been to touch them at all, unless superficially, without devoting a volume to each. These are, Turbines, Gearing, Propellers, Valve motions; Governors, with or without Variable Cut-offs; and Trains of gearing, as clock trains. Of turbines, I have only taken one of each of the three essentially different kinds, with a simple description of its construction and action. On gearing, I have been reasonably full, giving the substance of what need be known in behalf of proper practice, and with simple explanations.
