ANOTHER BOOK BY THE SAME AUTHOR

A bigger and more comprehensive work on the same subject.

“The How and Why of the Automobile”

Did you ever read a book which gave you just the information you wanted without being compelled to go through page after page of introduction and history?

¶ Did you ever talk to a man who came over on your side of the fence and talked WITH you and not AT you—who explained things in such a way that you laughed at yourself afterwards for not understanding the subject before—it was really so simple?

¶ Do you remember when you used to study by outlines—how difficult problems unfolded themselves—how the logical sequence of facts seemed to make what you expected to find hard, readily understandable?

¶ Do you remember the innumerable times you have said to yourself “If I only had somebody here to explain things—someone who would go through this proposition with me until I understood it—someone who would use homely and familiar examples to explain things, instead of talking over my head by using technical terms?”

¶ The author realized all these difficulties himself, because he has been through it all. Not only that, but his experience as an instructor of a large motor school taught him the way to explain the various parts of a motor vehicle in simple language, so that even the boy of fifteen could understand and appreciate them.

¶ For instance, did you ever think that the physician uses a form of carburetor whenever he gives chloroform or ether—do you realize that a shotgun is a form of gas engine whose action is almost identical with that of an automobile motor?

¶ Do you want to know what a sliding gear transmission is—explained in such simple language that anyone can understand it?

¶ Would you like to see what’s inside of an automobile engine—would you like to know the name of every part—be able to talk intelligently about it and be your own mechanic—tell your chauffeur what to do—know when he is bluffing you?

¶ In a word, would you like to know all about a motor car—how it works—how to drive it and how to take care of it? Then subscribe for a copy of

“THE HOW AND WHY OF THE AUTOMOBILE”

A book of practical information for seekers after the fundamental facts regarding the gasoline engine and its application to the motor car.

Interesting and instructive to both the beginner and the expert—the former for information, the latter for reference.

Written by Fay L. Faurote, B. S. (M. E.), for five years closely associated with the Experimental Department of a pioneer automobile factory, for two years instructor in the Detroit Motor School.

The book, which is handsomely bound in full cloth, printed on high-grade enameled paper, contains over 200 pages and 250 illustrations and covers the following subjects:

CONTENTS

General Theory of Gas Engines—Simple explanation of cycle—The four-stroke cycle—The two-stroke cycle—Advantages and disadvantages of each.

Motor Design—Cylinder, what it is and its use. Valves, mechanical and automatic—Forms of valves—Valve timing and its influence on the motor—Valve grinding, how to do it—Valve nomenclature. Crank Case—The construction Bearings—Accessibility—Working parts—Uses. A crank case oiling system. Crank Shafts—What they are—One, two, four and six-cylinder crank shafts—Crank case diagram, showing instantly conditions in all cylinders—Diagram showing firing points and sequence of same. Connecting Rods—Construction and material—Bearings and lubrication. Pistons—Piston rings—Piston pins.

The Carburetor—A very simple explanation of carburetion—The mixing valve—A few of the first types—Some of the modern carburetors—Foreign carburetors.

Ignition—The make and break system—A simple explanation of the apparatus used. The Jump Spark System—Electrical units. Sources of Electricity—The dry cell—The storage cell—Dynamos and magnetos—The spark coil—Commutators and timing devices—Spark plugs—Wiring diagrams.

Cooling System—Air Cooling. Water Cooling—Direction of circulation—Radiators—Water pumps—Fans—Anti-freezing solutions.

The Transmission—Reason for and use of transmission. Simple Explanation of Action—Individual clutch type—The sliding gear—The three speed progressive—The three speed selective—The four speed selective—Planetary gear—Friction drive.

Methods of Driving—Single chain drive—Double chain drive—Bevel gear drive.

Running Gear—Front Axle—Construction of—Steering Gear. Rear Axle—Differential gear—The live axle—The dead axle—Wheel construction—Bearings.

Horse Power Determinations—Engine testing—Indicated horse power—Brake horse power—Mechanical and heat efficiency—Road testing.

What a Prominent Trade Paper Says About It.

A Handbook of Practical Value—The latest addition to the popular type of automobile handbook. “The How and Why of the Automobile,” by Fay L. Faurote, fulfills what its author has set himself to achieve, namely, to present a plain, easily understood description of the modern automobile. Assuming that his reader knows nothing about the subject, the author introduces the automobile in as simple and untechnical a manner as possible. The entire field is covered and covered so completely that the work can be recommended as a handbook for beginners or those with only a limited knowledge of this subject.—Automobile, April 18.
