DIES METAL WORK

DIES: THEIR CONSTRUCTION AND USE FOR THE MODERN WORKING OF SHEET METALS. By J. V. Woodworth.

A most useful book, and one which should be in the hands of all engaged in the press working of metals; treating on the Designing, Constructing, and Use of Tools, Fixtures and Devices, together with the manner in which they should be used in the Power Press, for the cheap and rapid production of the great variety of sheet-metal articles now in use. It is designed as a guide to the production of sheet-metal parts at the minimum of cost with the maximum of output. The hardening and tempering of Press tools and the classes of work which may be produced to the best advantage by the use of dies in the power press are fully treated. Its 505 illustrations show dies, press fixtures and sheet-metal working devices, the descriptions of which are so clear and practical that all metal-working mechanics will be able to understand how to design, construct and use them. Many of the dies and press fixtures treated were either constructed by the author or under his supervision. Others were built by skilful mechanics and are in use in large sheet-metal establishments and machine shops. 5th Edition. Price

PUNCHES, DIES AND TOOLS FOR MANUFACTURING IN PRESSES. By J. V. WOODWORTH.

This work is a companion volume to the author's elementary work entitled "Dies, Their Construction and Use." It does not go into the details of die-making to the extent of the author's previous book, but gives a comprehensive review of the field of operations carried on by presses. A large part of the information given has been drawn from the author's personal experience. It might well be termed an Encyclopedia of Die-Making, Punch-Making, Die-Sinking, Sheet-Metal Working, and Making of Special Tools, Subpresses, Devices and Mechanical Combinations for Punching, Cutting, Bending, Forming, Piercing, Drawing, Compressing and Assembling Sheet-Metal Parts, and also Articles of other Materials in Machine Tools. 2d Edition. Price. $4.00 DROP FORGING, DIE-SINKING AND MACHINE-FORMING OF STEEL. By J. V. WOODWORTH.

This is a practical treatise on Modern Shop Practice, Processes, Methods, Machine
Tools, and Details treating on the Hot and Cold Machine-Forming of Steel and Iron
into Finished Shapes; together with Tools, Dies, and Machinery involved in the
manufacture of Duplicate Forgings and Interchangeable Hot and Cold Pressed Parts
from Bar and Sheet Metal. This book fills a demand of long standing for information
regarding drop-forgings, die-sinking and machine-forming of steel and the shop
practice involved, as it actually exists in the modern drop-forging shop. The processes

of die-sinking and force-making, which are thoroughly described and illustrated in this
admirable work, are rarely to be found explained in such a clear and concise manner
as is here set forth. The process of die-sinking relates to the engraving or sinking of
the female or lower dies, such as are used for drop-forgings, hot and cold machine
forging, swedging and the press working of metals. The process of force-making
relates to the engraving or raising of the male or upper dies used in producing the
lower dies for the press-forming and machine-forging of duplicate parts of metal.
In addition to the arts above mentioned the book contains explicit information re-
garding the drop-forging and hardening plants, designs, conditions, equipment, drop
hammers, forging machines, etc., machine forging, hydraulic forging, autogenous
welding and shop practice. The book contains eleven chapters, and the information
contained in these chapters is just what will prove most valuable to the forged-metal
worker. All operations described in the work are thoroughly illustrated by means of
perspective half-tones and outline sketches of the machinery employed. 300 detailed
illustrations.

DRAWING SKETCHING PAPER

PRACTICAL PERSPECTIVE. BY RICHARDS and COLVIN.

Shows just how to make all kinds of mechanical drawings in the only practical perspective isometric. Makes everything plain so that any mechanic can understand a sketch or drawing in this way. Saves time in the drawing room, and mistakes in the shops. Contains practical examples of various classes of work. 4th Edition. 50 cents

LINEAR PERSPECTIVE SELF-TAUGHT. By HERMAN T. C. KRAUS.

This work gives the theory and practice of linear perspective, as used in architectural,
engineering and mechanical drawings. Persons taking up the study of the subject
by themselves will be able, by the use of the instruction given, to readily grasp the
subject, and by reasonable practice become good perspective draftsmen.
The arrange-
ment of the book is good; the plate is on the left-hand, while the descriptive text
follows on the opposite page, so as to be readily referred to. The drawings are on
sufficiently large scale to show the work clearly and are plainly figured. There is
included a self-explanatory chart which gives all information necessary for the thorough
understanding of perspective. This chart alone is worth many times over the price of
the book. 2d Revised and enlarged Edition.

SELF-TAUGHT MECHANICAL DRAWING AND ELEMENTARY MACHINE DESIGN. By F. L. SYLVESTER, M.E., Draftsman, with additions by ERIK OBERG, associate editor of "Machinery."

This is a practical treatise on Mechanical Drawing and Machine Design, comprising the first principles of geometric and mechanical drawing, workshop mathematics, mechanics, strength of materials and the calculations and design of machine details.

The author's aim has been to adapt this treatise to the requirements of the practical mechanic and young draftsman and to present the matter in as clear and concise a manner as possible. To meet the demands of this class of students, practically all the important elements of machine design have been dealt with, and in addition algebraic formulas have been explained, and the elements of trigonometry treated in the manner best suited to the needs of the practical man. The book is divided into 20 chapters, and in arranging the material, mechanical drawing, pure and simple, has been taken up first, as a thorough understanding of the principles of representing objects facilitates the further study of mechanical subjects. This is followed by the mathematics necessary for the solution of the problems in machine design which are presented later, and a practical introduction to theoretical mechanics and the strength of materials. The various elements entering into machine design, such as cams, gears, sprocket-wheels, cone pulleys, bolts, screws, couplings, clutches, shafting and fly-wheels, have been treated in such a way as to make possible the use of the work as a text-book for a continuous course of study. It is easily comprehended and assimilated even by students of limited previous training. 330 pages, 215 engravings. Price . . $2.00
