But now all that is changed. The old type steering mechanism was imperfect; the attachment of the wheels to the axles had to be modified; the wheels themselves entirely revolutionized; speed changing and reversing especially adapted for quick and positive work; and even the easy starting of the motor had to be provided for.
The entire equipment required a multiplicity of new devices, such as signaling apparatus, lighting systems, safety appliances, means to prevent skidding, wind shields, a reorganization of body and seating arrangement, and a reconstruction of the springs and their attachment to the chassis.
The electrical part has made as rapid strides, and in the development the sparking mechanism has approached perfection, and brought into existence a wonderful variety of systems, so that each cycle of improvements has made them more efficient, but simpler to construct, understand and use.
It is a rare thing to-day to see any of the power machines dragged home by horse power. Not many years ago this was a common sight. The size, shape, and materials used, have been understood by scientific analysis and study, so that breakage, under ordinary uses, is not at all a common thing.
It is the aim of this book to show in as simple a manner as possible how this wonderful transformation has been brought about, and to furnish one or more types of each element, properly constructed and arranged, so that the boy may understand how each part is built, and the particular reasons for the structures.
In no branch of manufactures can be found such a variety of technical designations as have grown out of this industry. By virtue of necessity, many of these names have been coined to suit the conditions. This knowledge is imparted in these pages, which contains a complete glossary of every term used in the art.

CHAPTER I
AUTOMOBILE HISTORY AND DEVELOPMENT
It is generally believed that automobiles originated within the present century, this idea having gained currency because, until within the past twenty years, no practical machines were put on the market.
