THE PERIOD OF APPLICATION. 53 The sketch is that given by the inventor in his consists (Fig. 18) of a steam-boiler, a, from which steam isled through the cock, c, to the working cylinder, n. The waterbeneath the floating-piston, A, which latter serves simply asa cushion to protect the steam from sudden condensation orcontact with the water, is forced into the vessel r r, which. Tis. IS.—Papins Engine and Water-Wheel, A. d. 1707. is a large air-chamber, and which serves to render the out-flow of water comparatively uniform, and the discharge oc-curs by means of the pipe g, from which the water rises tothe desired height. A fresh supply of water is introducedthrough the funnel k, after condensation of the steam in n,and the operation of expulsion is repeated. This machine is evidently a retrogression, and Papin,after having earned the honor of having invented the firststeafti-engine of the typical form which has since becomeso universally applied, forfeited that credit by his evidentignorance of its superiority over existing devices, and byattempting unsuccessfully to perfect the inferior device ofanother inventor. Subsequently, Papin made an attempt to apply thesteam-engine to the propulsion of vessels, the account ofwhich will be given in the chapter on Steam-Navigation. Again disappointed, Papin once more visit
