Works in Iron - Bridge and Roof Structures #270681

Although published under an old title - adopted four years ago for a book on the same subject - the present Work is entirely new. Not professing to deal with the pure science of engineering practice, it treats of practical considerations which affect the choice of design in regard to iron structures. The qualities of material, the classification of different systems, the incidents of transport, and the methods of erection, are stated from a manufacturer's point of view, with a special reference to comparative cost.<br><br>The "Examples" given on pages 135 to 190, and 239 to 289, are all selected from Works constructed by Andrew Handyside & Co., at Derby, and of which the author is personally cognisant.<br><br>The need often felt by engineers for a dictionary of foreign technical words suggested the Vocabulary given in the Appendix.<br><br>The author is glad here to acknowledge the assistance rendered him by Mr. A. Buchanan, of Derby (under whose direction all the Examples of Structures referred to above were carried out), and by Mr. Max Am Ende, of London.<br><br>Preface To Second Edition.<br><br>In the revision necessary to a new Edition, the fluctuations in prices on page 4 have been continued to March, 1876; the remarks on the qualities of iron and steel have been modified; and some new Examples (Nos. 8, 10, 30, 55, 61) of structures have been added.
