AUTOMOBILES AND MOTORCYCLES

THE MODERN GASOLINE AUTOMOBILE-ITS DESIGN, CONSTRUCTION,
MAINTENANCE AND REPAIR. BY VICTOR W. PAGE, M.E.

The latest and most complete treatise on the Gasoline Automobile ever issued. Written
in simple language by a recognized authority, familiar with every branch of the auto-
mobile industry. Free from technical terms. Everything is explained so simply
that anyone of average intelligence may gain a comprehensive knowledge of the
gasoline automobile. The information is up-to-date and includes, in addition to an
exposition of principles of construction and description of all types of automobiles and
their components, valuable money-saving hints on the care and operation of motor-
cars propelled by internal combustion engines. Among some of the subjects treated
might be mentioned: Torpedo and other symmetrical body forms designed to reduce
air resistance; sleeve valve, rotary valve and other types of silent motors; increasing
tendency to favor worm-gear power-transmission; universal application of magneto
ignition; development of automobile electric-lighting systems; block motors; under-
slung chassis; application of practical self-starters; long stroke and offset cylinder
motors; latest automatic lubrication systems; silent chains for valve operation and
change-speed gearing; the use of front wheel brakes and many other detail refinements.
By a careful study of the pages of this book one can gain practical knowledge of auto-
mobile construction that will save time, money and worry. The book tells you just
what to do, how and when to do it. Nothing has been omitted, no detail has been
slighted. Every part of the automobile, its equipment, accessories, tools, supplies,
spare parts necessary, etc., have been discussed comprehensively. If you are or
intend to become a motorist, or are in any way interested in the modern Gasoline
Automobile, this is a book you cannot afford to be without. Over 850 6x9 pages-
and more than 600 new and specially made detail illustrations, as well as many full-
page and double-page plates, showing all parts of the automobile. Including 12 large
folding plates. Price
