STEEL
AMERICAN STEEL WORKER. By E. R. MARKHAM. This book tells how to select, and how to work, temper, harden, and anneal steel for everything on earth. It doesn't tell how to temper one class of tools and then leave the treatment of another kind of tool to your imagination and judgment, but it gives careful instructions for every detail of every tool, whether it be a tap, a reamer or just a screw-driver. It tells about tempering of small watch springs, the hardening of cutlery, and the annealing of dies. In fact there isn't a thing that a steel worker would want to know that isn't included. It is the standard book on selecting, hardening, and tempering all grades of steel. Among the chapter headings might be mentioned the following subjects: Introduction; the workman; steel; methods of heating; heating tool steel; forging; annealing; hardening baths; baths for hardening; hardening steel; drawing the temper after hardening; examples of hardening; pack hardening; case hardening; spring tempering; making tools of machine steel; special Steels; steel for various tools; causes of trouble; high speed steels, etc. 366 pages. Illustrated. $2.50
HARDENING, TEMPERING, ANNEALING, AND FORGING OF STEEL. By J. V. WOODWORTH. A new work treating in a clear, concise manner all modern processes for the heating, annealing forging, welding, hardening, and tempering of steel, making it a book of great practical value to the metal-working mechanic in general, with special directions for the successful hardening and tempering of all steel tools used in the arts, including milling cutters, taps, thread dies, reamers, both solid and shell, hollow mills, punches and dies, and all kinds of sheet metal working tools, shear blades, saws, fine cutlery, and metal cutting tools of all description, as well as for all implements of steel both large and small. In this work the simplest and most satisfactory hardening and tempering processes are given. The uses to which the leading brands of steel may be adapted are concisely presented, and their treatment for working under different conditions explained, also the special methods for the hardening and tempering of special brands. A chapter devoted to the different processes for Case-hardening is also included, and special reference made to the adoption of machinery steel for tools of various kinds. 4th Edition 288 pages. 201 Illustrations. Price $2.50
TURBINES
MARINE STEAM TURBINES. By DR. G. BAUER and O. LASCHE. Assisted by E. Ludwig and H. Vogel. Translated from the German and edited by M. G. S. Swallow. This work forms a supplementary volume to the book entitled "Marine Engines and Boilers." The authors of this book, Dr. G. Bauer and O. Lasche, may be regarded as the leading authorities on turbine construction. The book is essentially practical and discusses turbines in which the full expansion of steam passes through a number of separate turbines arranged for driving two or more shafts, as in the Parsons system, and turbines in which the complete expansion of steam from inlet to exhaust pressure occurs in a turbine on one shaft, as in the case of the Curtis machines. It will enable a designer to carry out all the ordinary calculations necessary for the construction of steam turbines, hence it fills a want which is hardly met by larger and more theoretical works. Numerous tables, curves and diagrams will be found, which explain with remarkable lucidity the reason why turbine blades are designed as they are, the course which steam takes through turbines of various types, the thermodynamics of steam turbine calculation, the influence of vacuum on steam consumption of steam turbines, etc. In a word, the very information which a designer and builder of steam turbines most requires. The book is divided into parts as follows: 1. Introduction. 2. General remarks on the design of a turbine installation. 3. The calculation of steam turbines. 4. Turbine design. 5. Shafting and propellers. 6. Condensing plant. 7. Arrangement of turbines. 8. General remarks on the arrangement of steam turbines in steamers. 9. Turbine-driven auxiliaries. 10. Tables. Large octavo. 214 pages. Fully illustrated and containing 18 tables. Including an entropy chart. Price, net, $3.60
