    Gambles Apparatus for the Concentration §c. of certain Solutions, §c. the same is to be performed, to be enrolled in His Majesty’s High Court of Chancery within four calendar months next and immediately after the date of the said recited Letters Patent, as in and by the same, relation being there¬ unto had, may more fully and at large appear. NOW KNOW YE, that, in compliance with the said proviso, I do hereby 5 declare that the nature of my said Invention, and the manner in which the same is performed, is particularly described in manner following, and by the Drawings hereunto annexed, viz1;— . The apparatus I employ for the purposes of evaporation, distillation, inspis- sation, and desiccation is represented in the accompanying Drawing by Fig. 1st. 10 A, the boiler, consisting of two metallic vessels placed the one within the other. The Ranches B, B, at top are formed to correspond, and are made air-tight by screws and cement in the usual way. The inner is seperated from the outer vessel by a space of two or three inches at bottom and sides. The outer vessel has a stroop at the bottom for drawing off the contents of the intermediate 15 space. The boiler is set over a furnace in the usual wray, which it is unne¬ cessary here to describe. C is a curved pipe, from one to two inches in diameter more or less, according to the dimensions of the apparatus; the curve rises about eighteen inches, and its legs stand distant from each other about two feet. D, an air pipe proceeding from the most elevated part of the 20 curved pipe, about one inch in diameter, provided with a stop-cock at E, and rising as high as the reservoir F. One leg of the curved pipe is attached at B to the Ranch of the inner compartment of the vessel A. The other leg is attached to the side of the reservoir F; and thus a constant communication is maintained between the chamber of vessel A and the reservoir F. I shall 25 in future denominate the space between the outer and inner compartments of vessel A, the chamber; the fluid it contains, the medial fluid; and the liquid to be operated on, the boiling liquid. In using this apparatus, I pour into the reservoir F any liquid the boiling point of which is thirty-five degrees or more higher than the liquid to be boiled. As soon as said liquid rises as high as 30 the dotted line G, H, it passes through the curved tube, fills the chamber between the two compartments of the boiler A, and expels the air therefrom through the air pipe D. As soon as the chamber is filled, and the medial liquid remains stationary at the line G, H, that is, above the level of the curved pipe, the interior of the vessel A may be filled with the boiling liquid, 35 and the fire lighted in the furnace. As soon as the medial liquid is raised about thirty degrees higher than the boiling point of the boiling liquid, the latter will commence boiling, while the medial fluid will not itself boil. I have uniformly remarked the important fact that any fluid medium forming
