MODERN MARINE ENGINEERING

Illustrated With Thirty Six Correctly Colored Plates and Two Hundred and Forty Wood-CutsSuffice it to say that many worse peculiarities have appeared since the days of Hero, and also have been brought forward as perfection personified. The vital intention of the advocates of rotary engines is, to dispense with the crank and the connecting rod. Now these important details mayihe said to be the partial regulators of the power of the engine. It is well known that a lever of any length exerts a power equivalent, due to the force exerted, hence we find that a long crank is more powerful than a short one, although the force exerted be alike. The many inventors of the rotary engines do not in all cases ignore the application of this natural law, but they certainly lessen the power in proportion to the area exposed to the steam. It may be argued, that what is lost by the absence of the crank, is gained by the eccentricity of the piston and the velocity avail able, but these attainments are counteracted by the liability of all the working parts to dis arrangement, and thereby cause a leakage of the steam. From these facts it may not be won dered at, that, the ordinary cylinder and piston with a reciprocal motion, still takes the lead as a prime mover. Enough has now been said to enable the formation of a correct idea, as to what is, the best class of engine for marine purposes, transmission of power now only.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
