"I have been engaged in the construction of toothed gearing all my life, and many years ago felt the want of such a book as this. There is no work yet of this particular type published either in England or America, none which deals with the subject of toothed gearing from the standpoint of the workshop and drawing-office, none which goes over the whole field as this does. Only so much mathematics is introduced as is necessary to establish fundamental principles. But the practical methods of formation of tooth profiles, both cycloidal and involute, special forms, and the employment of Willis's Odontograph, have been treated fully. The various screw gears, angle wheels, worm wheels, helical wheels, etc. have received full illustration, and the essential elements of the practice of machine moulding have been described." - from Preface.…
