Excerpt from Appleby's Illustrated Handbook of Machinery, Vol. 1: Prime Movers, Including Fixed, Portable and Marine Engines, Boilers and Fittings, Water Heaters and Accessories, Gas, Oil, and Heated Air Engines, Dynamos and Electric Motors Much information relating to the matters referred to in the following pages will be found in text books, treatises, and trade catalogues, but it is treated, for the most part, in a manner too technical to be of real service to many who - although buyers and users of machinery - may not possess intimate knowledge of details of construe tion, the cost of machines, their productive capacity. &c., Conscious, as the Writer is, that the efforts of no single individual will suffice to cover the ground thus left vacant, he has attempted to cover some of it by presenting information with regard to the construe tion, the approximate prices of the machines described, the probable output, and other data which will serve as a basis for estimating the Cost of the machinery and, approximately, the cost of working it. The arrangement adopted in the first edition of appleby's handbook OF machinery, which was published in 1869, has been to a large extent adhered to in this edition, but the advances made in all branches of mechanical construction since that time, have been so incredibly great and varied, that' nothing which appeared in the above-named edition, or the numerous reprints of it, have been found suitable for reproduction, so that the descriptive matter has been en tirely re-written and - as far as practicable - corrected up to this date. It is to be regretted that lack of space precludes a more extended notice of some (and causes the complete omission of other) interesting inventions and improvements in special departments of engineering design and the selection of subjects is necessarily limited to those which may be regarded as being of general interest.
