Another improvement consists in heating the water supplied by the feed pumps previous to entering the boiler. For this purpose the inventor proposes that the water, after leaving the feed pumps and before entering the boiler, shall pass through a chamber or series of pipes exposed to tb« action of heated vapours, which pass through the tubes into the smoke box, BO that the water may become highly heated before entering the boiler. LOCOMOTIVE ENOINES. Henry Samuel Ravser, of Ripley, Derby, Gent., for "certain imfrrore- ments in locomotive ;âGranted September 4, 1845 ; Enrolled March 4, 1840. The object of the inventor is to construct a locomotive engine, which it to be propelled by the pressure of the atmosphere acting upon the exterior sur- face of a vessel or vessels exhausted of air. The annexed diagram shows a side elevation of Mr. Rayner's locomotive, which may be termed a perpt^tual locomoti\e, being of that class of machines when once started will continue its course so long as liie parts of the apparatus will hold together ! a re- presents a rectangular or oblong vessel of a wedge-shape form mounted npua. the carriage framing; above this vesse
