Hardbound. Etat : Very Good. No Jacket. First Edition. A VERY GOOD, bright, clean, tight, scholar/collector-worthy copy. PROLIFICALLY ILLUSTRATED with hundreds of black-and-white photographs, diagrams and drawings with accompanying descriptive captions. From the PREFACE: "The chapters of this book originally formed articles written for the "AMERICAN ELECTRICIAN" by designers of the apparatus described, which, in many cases, had been actually built and used prior to the publication of the description. The designs were all prepared with a view to reducing to the simplest degree the tools and facilities necessary for the construction of the apparatus. The designs for such of the small motors as have not been built have been calculated with ample allowance for variations in the quality of iron and steel, so that any discrepancy between the performance predicted for these machines and that actually realized will be in favor of the motor, if the material is of a grade at all allowable in good foundry practice." 34 Chapters. Burnt orange buckram boards with gold gilt lettering on spine. 262 pages followed by 7 pages of advertisements for other American Electrician Co. related publications. LG6.…
