A propos du livre

Présentation de l'éditeur

Thornewill and Warham; Blowing Engines by the same firm; Hydraulic Pumping Engines by Mr. E. B. Ellington; Botary Pumping Dock Engines by Messrs. Hick, Hargreaves Co. of Bolton, also by Messrs.

The leading machinery above mentioned is illustrated in Drawings Nos. 24 to 35. The author believes most of the chief types of pumping machinery in use in this country are now described in the book, and he trusts the value of the information contained will be much increased by the additions made. He will be much indebted to any one who will favour him with any suggestions or extra detail for a future edition of the book, it being his intention as far as possible to describe at least one type of the most modern kind of pumping machinery at present in use.

Présentation de l'éditeur

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself.

We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
