Excerpt from Practice and Theory of the InjectorTO henri jacques giffard, an eminent French mathe matician and engineer, belongs the honor of having invented the simplest apparatus for feeding boilers that has ever been devised, utilizing in a novel and ingenious way the latent power of a discharging jet of steam.From the time of his graduation from L' Ecole Centrale in 1849, Gifi'ard had directed his energies to the study of aeronautics and had spent much time in developing a light steam motor for propelling balloons, it is, therefore, not strange that he should also have attempted to devise a com pact and convenient substitute for the steam pumps then in use. Already a number of patents had been granted him for the application of the steam engine to aerial navigation and for other correlated inventions When, on May 8, 1858, letters patent Were issued for L' [njedeur Automoteur. His early technical education and wonderful ingenuity well fitted him for breaking away from the old beaten paths and start ing out on a new line of discovery, and in view of the originality of his work he fully deserved the unqualified praise accorded him by his contemporaries.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
