Appleton's Dictionary of Machines, Mechanics, Engine-Work, and Engineering, Vol. 1 of 2 (Classic Reprint)

Excerpt from Appleton's Dictionary of Machines, Mechanics, Engine-Work, and Engineering, Vol. 1 of 2

IN presenting to the public a new edition. Of the Dictionary of Mechanics, Machines, Engine Work, and Engineering, the publishers have thought it necessary that the Whole work should be revised; that those novelties which were presented in the original work, and have not stood the test of use, should be struck out; those processes which have been superseded, should give place to those at present employed; and that those new machines which have not as yet been fully tested by time, but bid fair to be of practical value, as well as older machines previously omitted, should be added.

They are aware that in the first work manyr errors both in com mission and in omission crept in - errors in judgment, and errors in arrangement - that though in general standard authors were drawn from, yet credit was often not given to the authority in the article itself. Time, experience, and consultation with persons of practical minds, have helped to correct errors in judgment. As to the arrange ment, many articles were introduced into the original edition under their least characteristic heads; references were not full, often wrong.

This has been remedied: the captions of articles have been changed, references have been made fuller and more accurate, and we trust that the knowledge contained in this work may be much more available.
