Savery Engine

“Savery’s Steam Engine. The adjoining figure illustrates the apparatus employed by Savory. It consists of a furnace and a boiler B; from the latter, two pipes, furnished with stop-cocks C, proceed to two steam vessels S, only one of which is shown in the figure, the other being immediately behind it. Into the bottom of each of these steam vessels is inserted a branching pipe, connected with a descending main pipe D, and an ascending main pipe A; each branching pipe is furnished with valves a, b, which open upwards, and prevent, by their action, the return of any water which may have been forced up through them.” —Comstock, 1850
