Description:
Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.

“For a machine for Raising Water by Atmospheric Pressure; Samuel M‘Cune, Wilmington, Clinton county, Ohio, August 25.

Captain Savary's engine, was, in its day, a thing of great merit, but its reinvention will scarcely confer immortality upon any one of the numerous candidates for that honour. The present patentee appears sensible, however, that there is nothing new in the principle of the engine which he has patented, as he says “it is expressly to be understood, that what I claim as new, is, the mechanical application of the above." We must not, therefore, place him in the class of those who have simplified the steam engine, by restoring it to the state in which it existed a hundred and thirty years ago, as he merely proposes to open and close his valves, introduce his jets, and perform, some other requisite operations, by an arrangement of parts somewhat different from that formerly pursued. There are to be two cisterns, which are alternately to be filled with steam, in order to its being condensed by jets of cold water; they are then to be filled with water by the pressure of the atmosphere upon that contained in a reservoir below, into which pipes, furnished with valves, pass from the receivers, or cisterns. The water is to be let out from these upon a water wheel, and from the shaft of this wheel the motion is derived which is necessary to the introducing the condensing water, to the opening and closing of the valves, and for other purposes. We do not think it necessary to describe the manner of doing these things, as there does not appear to us to be any particular merit in them. And when it is recollected that the cylinder and piston engine has long since superseded the use of captain Savary's, even where the only operation to be performed is the raising of water, no one versed in the history of mechanical inventions would believe that it was any great improvement to use the latter in turning a mill.”
