DROP FORGING, DIE-SINKING AND MACHINE-FORMING OF STEEL. By
J. V. WOODWORTH.
This is a practical treatise on Modern Shop Practice, Processes, Methods, Machines,
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 r
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

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 neces-
sary 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 &
continuous course of study. It is easily comprehended and assimilated even by
students of limited previous training. 330 pages, 215 engravings. Price $2.00

. $1.00 ELECTRIC FURNACES AND THEIR INDUSTRIAL APPLICATION. By J.
This is a book which will prove of interest to many classes of people; the manufacturer
who desires to know what product can be manufactured successfully in the electric
furnace, the chemist who wishes to post himself on the electro-chemistry, and the
student of science who merely looks into the subject from curiosity. The book is
not so scientific as to be of use only to the technologist nor so unscientific as to suit
only the tyro in electro-chemistry; it is a practical treatise of what has been done.
and of what is being done, both experimentally and commercially, with the electric
furnace. In important processes not only are the chemical equations given, but
complete thermal data are set forth, and both the efficiency of the furnace and the cost
of the product are worked out, thus giving the work a solid commercial value aside
from its efficacy as a work of reference. The practical features of furnace building are
given the space that the subject deserves. The forms are refractory materials used in
the linings, the arrangement of the connections to the electrodes, and other important de-
tails are explained. 288 pages. New Revised Edition. Fully illustrated. Price . $8.00 ELECTRIC LIGHTING AND HEATING POCKET-BOOK. By SYDNEY F.
