facturing are given; also a description of the various devices for feeds and thread
cutting mechanisms from early efforts in this direction to the present time. Lathe
design is thoroughly discussed, including back gearing, driving cones, thread-cutting
gears, and all the essential elements of the modern lathe. The classification of lathes
is taken up, giving the essential differences of the several types of lathes including,
as is usually understood, engine lathes, bench lathes, speed lathes, forge lathes, gap
lathes, pulley lathes, forming lathes, multiple-spindle lathes, rapid-reduction lathes,
precision lathes, turret lathes, special lathes, electrically-driven lathes, etc. In addi-
tion to the complete exposition on construction and design, much practical matter on
lathe installation, care and operation has been incorporated in the enlarged 1915 edi-
tion. All kinds of lathe attachments for drilling, milling, etc., are described and
complete instructions are given to enable the novice machinist to grasp the art of lathe
operation as well as the principles in volved in design. A number of difficult machining
operations are described at length and illustrated. The new edition has nearly 500
pages and 350 illustrations. Price

MACHINE-SHOP PRACTICE

AMERICAN TOOL MAKING AND INTERCHANGEABLE MANUFACTURING.
By J. V. WOODWORTH.

A "shoppy" book, containing no theorizing, no problematical or experimental devices,
there are no badly proportioned and impossible diagrams, no catalogue cuts, but a
valuable collection of drawings and descriptions of devices, the rich fruits of the author's
own experience. In its 500-odd pages the one subject only, Tool Making, and what-
ever relates thereto, is dealt with. The work stands without a rival. It is a complete
practical treatise on the art of American Tool Making and system of interchangeable
manufacturing as carried on to-day in the United States. In it are described and
illustrated all of the different types and classes of small tools, fixtures, devices, and
special appliances which are in general use in all machine-manufacturing and metal-
working establishments where economy, capacity, and interchangeability in the pro-
duction of machined metal parts are imperative. The science of jig making is exhaus-
tively discussed, and particular attention is paid to drill jigs, boring, profiling and milling
fixtures and other devices in which the parts to be machined are located and fastened
within the contrivances. All of the tools, fixtures, and devices illustrated and de-
scribed have been or are used for the actual production of work, such as parts of drill
presses, lathes, patented machinery, typewriters, electrical apparatus, mechanical ap-
pliances, brass goods, composition parts, mould products, sheet metal articles, drop-
forgings, jewelry, watches, medals, coins, etc. 531 pages. Price

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 is 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.

MECHANICAL MOVEMENTS, POWERS, AND DEVICES. BY GARDNER D. HISCOX.

This is a collection of 1,890 engravings of different mechanical motions and appliances, accompanied by appropriate text, making it a book of great value to the inventor, the draftsman, and to all readers with mechanical tastes. The book is divided into eighteen sections or chapters, in which the subject-matter is classified under the following heads: Mechanical Powers; Transmission of Power; Measurement of Power; Steam Power; Air Power Appliances; Electric Power and Construction; Navigation and Roads; Gearing; Motion and Devices; Controlling Motion; Horological; Mining; Mill and Factory Appliances; Construction and Devices; Drafting Devices; Miscellaneous Devices, etc. 12th edition. 400 octavo pages. Price.. $2.50

MECHANICAL APPLIANCES, MECHANICAL MOVEMENTS AND NOVELTIES
OF CONSTRUCTION. By GARDNER D. Hiscox.

This is a supplementary volume to the one upon mechanical movements. Unlike the
first volume, which is more elementary in character, this volume contains illustrations
and descriptions of many combinations of motions and of mechanical devices and
appliances found in different lines of machinery, each device being shown by a line
drawing with a description showing its working parts and the method of operation.
From the multitude of devices described and illustrated might be mentioned, in
passing, such items as conveyors and elevators, Prony brakes, thermometers, various
types of boilers, solar engines, oil-fuel burners, condensers, evaporators, Corliss and
other valve gears, governors, gas engines, water motors of various descriptions, air
ships, motors and dynamos, automobile and motor bicycles, railway lock signals,
car couplers, link and gear motions, ball bearings, breech block mechanism for heavy
guns, and a large accumulation of others of equal importance. 1,000 specially made

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. Maxím says, "American machinists have become and are the finest me-
chanics 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 edition 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 in a practical manner. Fifth edition. 320 pages. 250 illustra
tions. Price .
