Book Description
Excerpt from Screw Propellers and Marine Propulsion The propelling screw is, in all probability, a very ancient contrivance. The date of its first application as an instrument of propulsion remains in oblivion, but it is said to have been known in China at a very early period. But it is in its connec tion with steam as a motive power to propel vessels that the following pages are chiefly devoted.

Book Description
Excerpt from Propellers A brief treatment is given of methods for determining the power required to propel a ship at a given speed, together with data for various types of ships and boats. It is believed that intelligent use of this material will give satisfactory results under ordinary conditions; the best results, expecially under extreme conditions, can be expected only by experienced designers who have specific information. All methods of designing ships and propellers are based, either explicitly or implicitly, on the theory of; mechanical similitude. The conclusions and methods of this theory may be stated briefly and used easily; a presentation of the theory is given at the end of the book for convenient reference.

Book Description
Albert Edward Seaton describes and discusses different methods and instruments for marine propulsion. The focus is on the screw propeller. Seaton gives an account of its history, leading features, forms and the materials used for it. In addition, he presents several screw propeller trials and experiments of the late 19th and early 20th century.Reprint of the original edition from 1909.

Book Description
Excerpt from The Screw Propeller: And Other Competing Instruments for Marine Propulsion Some thirty-two years ago, when engaged in putting forth the Manual of Marine Engineering, I could not find a single book on the Screw Propeller, or any text book containing such information on it as would enable a draughtsman to get out the leading dimensions, and much less to make a complete design of a screw suitable for any particular ship and conditions. At that time John Bourne's admirable book on the Screw Propeller was not only out of print, but out of date, and I fear no engineer could at any time have designed a screw which would give satisfactory results from what was contained in it. It was, however, many years after that I first saw his work, and my wonder then, as now, is that such a book was allowed to disappear, seeing how much of interest it contained. But perhaps the strongest comment on the knowledge of the screw propeller at that time is in the admission of the then engineer-in-chief of the British Navy, that he had settled the design of those for so very important a ship as the Iris, intended to be the fastest ship in the Navy, by copying that of hms. Himalaya, a ship built in 1854, with the result that the British Admiralty, with all its knowledge and opportunities, with all its records of tests and trials, perpetrated a blunder never equalled in the history of steam navigation, although in the mercantile marine there had been not a few mistakes. But even in modern times, notwithstanding the better knowledge and the aid of tank experiments, our best men do sometimes fail to achieve success, but the magnitude of the failure is inconsiderable compared with that of the Iris. In the Manual of Marine Engineering I attempted to supply the wants of designers by giving a rule or formula for each important dimension, generally based on scientific reasons, and always capable of giving results agreeable with the best and most successful practice.

Book Description
Excerpt from Screw Propellers: And Estimation of Power for Propulsion of Ships; Also Air-Ship Propellers John bourne, in his Treatise on the Screw Propeller, published in 1867, states that the screw propeller is, in all probability, a very ancient contrivance. In China it is said to have been known for ages; but in European countries the idea of a screw propeller appears to have been derived either from the windmill or smoke-jack, or from the screw of Archimedes, an instrument much used in some countries for raising water. Seaton, in his work on screw propellers, traces its develop ment from the time when man first used his hands as paddles, through the pulling oar and the scullin g oar, and the modified application of the latter in the form of the screw propeller.

Excerpt from Researches on the Performace of the Screw Propeller The forms of the blade contours collectively are shown in fig.1, and the thickness lay-out along the central axis of the blade by fig. 3, while the entire number in general view are shown in fig. 2. For making the propellers a wooden pattern was first prepared for the given pitch and for the widest blades or No. 8.

Book Description
Excerpt from History of Propellers and Steam Navigation: With Biographical Sketches of the Early Inventors Dr. Papin, a Frenchman, Captain Savery, and the Marquis of Worcester, preposed to propel vessels by steam power ap plied in some way to paddles, but the testimony which is left to posterity of their contrivances for that purpose, is so um satisfactory and vague that little can be made out of it. In 1726, a Dr. John Allen published a work in London in which he preposed to propel a vessel by having a horizon tal pipe Open at the stern, into which air or water was to be forced, to propel the boat forward by its reaction. The Doctor tried his scheme on a boat upon a canal, and he states that if steam was used as a power, he had no doubt but it could be moved at the rate of three miles per hour.
