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 regarding 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. Price =$2.50=

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

=The Modern Machinist.= By JOHN T. USHER.

This is a book, showing by plain description and by profuse

engravings made expressly for the work, all that is best, most

advanced, and of the highest efficiency in modern machine-shop

practice, tools and implements, showing the way by which and

through which, as Mr. Maxim says "American machinists have

become and are the finest mechanics in the world." Indicating as

it does, in every line, the familiarity of the author with every

detail of daily experience in the shop, it cannot fail to be of

service to any man practically connected with the shaping or

finishing of metals.

There is nothing experimental or visionary about the book, all

devices being in actual use and giving good results. It might be

called a compendium of shop methods, showing a variety of

special tools and appliances which will give new ideas to many

mechanics, from the superintendent down to the man at the bench.

It will be found a valuable addition to any machinist's library,

and should be consulted whenever a new or difficult job is to be

done, whether it is boring, milling, turning, or planing, as

they are all treated m a practical manner. Fifth edition. 320

pages. 250 illustrations. Price =$2.50=

=THE WHOLE FIELD OF MECHANICAL MOVEMENTS COVERED BY MR. HISCOX'S TWO

BOOKS=

_We publish two books by Gardner D. Hiscox that will keep you

from "inventing" things that have been done before, and suggest

ways of doing things that you have not thought of before. Many a

man spends time and money pondering over some mechanical

problem, only to learn, after he has solved the problem, that

the same thing has been accomplished and put in practice by

others long before. Time and money spent in an effort to

accomplish what has already been accomplished are time and money

LOST. The whole field of mechanics, every known mechanical

movement, and practically every device are covered by these two

books. If the thing you want has been invented, it is

illustrated in them. If it hasn't been invented, then you'll

find in them the nearest things to what you want, some movements

or devices that will apply in your case, perhaps; or which will

give you a key from which to work. No book or set of books ever

published is of more real value to the Inventor, Draftsman, or

practical Mechanic than the two volumes described below._

=Marine Engines and Boilers: Their Design and Construction.= By DR. G.

BAUER, LESLIE S. ROBERTSON and S. BRYAN DONKIN.

In the words of Dr. Bauer, the present work owes its origin to

an oft felt want of a condensed treatise embodying the

theoretical and practical rules used in designing marine engines

and boilers. The need of such a work has been felt by most

engineers engaged in the construction and working of marine

engines, not only by the younger men, but also by those of

greater experience. The fact that the original German work was

written by the chief engineer of the famous Vulcan Works,

Stettin, is in itself a guarantee that this book is in all

respects thoroughly up-to-date, and that it embodies all the

information which is necessary for the design and construction

of the highest types of marine engines and boilers. It may be

said that the motive power which Dr. Bauer has placed in the

fast German liners that have been turned out of late years from

the Stettin Works represent the very best practice in marine

engineering of the present day. The work is clearly written,

thoroughly systematic, theoretically sound; while the character

of the plans, drawings, tables, and statistics is without

reproach. The illustrations are careful reproductions from

actual working drawings, with some well-executed photographic

views of completed engines and boilers. 744 pages, 550

illustrations and numerous tables. Cloth. Price =$9.00 net=

~MINING~

the prospector. Only an elementary knowledge of geology and some

mining experience are necessary in order to understand this

work. With these qualifications, it will materially assist one

in his search for metalliferous mineral occurrences and, so far

as simple ores are concerned, should enable one to form some

idea of the possibilities of any he may find. Illustrated.

~STEEL~

=Steel: Its Selection, Annealing, Hardening, and Tempering.= By E. R.

MARKHAM.

This work was formerly known as "The American Steel Worker," but

on the publication of the new, revised edition, the publishers

deemed it advisable to change its title to a more suitable one.

It is the standard work on Hardening, Tempering, and Annealing

Steel of all kinds. 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 the 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.

400 pages. Very fully illustrated. Fourth edition. Price =$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 adaptation

of machinery steel for tools of various kinds, Fourth edition.

~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. 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 calculation 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. Large octavo, 214

pages. Fully illustrated and containing eighteen tables,

including an entropy chart. Price, net =$3.50=

~WATCH MAKING~

=Watchmaker's Handbook.= By CLAUDIUS SAUNIER.

No work issued can compare with this book for clearness and

completeness. It contains 498 pages and is intended as a

workshop companion for those engaged in watch-making and allied

mechanical arts. Nearly 250 engravings and fourteen plates are

included. This is the standard work on watch-making. Price

how to construct necessary shop equipment. Proceeds then to the

actual welding of all automobile parts, in a manner

understandable by every one. _Gives principles never to be

forgotten._ Aluminum, cast iron, steel, copper, brass, bronze,

and malleable iron are fully treated, as well as a clear

explanation of the proper manner to burn the carbon out of the

combustion head. This book is of utmost value, since the

perplexing problems arising when metal is heated to a melting

point are fully explained and the proper methods to overcome

them shown. 167 pages, fully illustrated. Price =$1.00=

=Everyday Engineering=

A monthly magazine devoted to practical mechanics for everyday men. Its

aim is to popularize engineering as a science, teaching the elements of

applied mechanics and electricity in a straightforward and

understandable manner. The magazine maintains its own experimental

laboratory where the devices described in articles submitted to the

Editor are first tried out and tested before they are published. This

important innovation places the standard of the published material very

high, and it insures accuracy and dependability.

The magazine is the only one in this country that specializes in

practical model building. Articles in past issues have given

comprehensive designs for many model boats, including submarines and

chasers, model steam and gasoline engines, electric motors and

generators, etc., etc. This feature is a permanent one in this magazine.

Another popular department is that devoted to automobiles and airplanes.

Care, maintenance, and operation receive full and authoritative

treatment. Every article is written from the practical, everyday man,

standpoint rather than from that of the professional.

The magazine entertains while it instructs. It is a journal of

practical, dependable information given in such a style that it may be

readily assimilated and applied by the man with little or no technical

training. The aim is to place before the man who leans toward practical

mechanics, a series of concise, crisp, readable talks on what is going

on and _how it is done_. These articles are profusely illustrated with

clear, snappy photographs, specially posed to illustrate the subject in

the magazine's own studio by its own staff of technically-trained

illustrators and editors.

=The subscription price of the magazine is one dollar per year of twelve

numbers. Sample copy sent on receipt of ten cents.=
