    Fall's Method of Heating all Kinds of Fluids. NOW KNOW YE, that in compliance with the said proviso, I, the said Robert Fall, do describe and ascertain the nature of my said Invention, and the manner in which the same is to be performed, to be as follows (that is to say):— 5 The vessel containing the fluid, which I call a boiler, may be made of any kind of metal. The fire is to be made under the boiler in the same manner as is now practised, whether by furnace or otherwise. At the back part of the boiler an aperture is to be made in its botom, or in its side near the botom, or in such other part as may best answer the draught of the furnace; into this 10 aperture, within side of the boiler, must be inserted the mouth of a pipe or flue, which after rising a little from its insertion makes a turn or bending to one hand, and then should run spirally round, or in such other manner within the fluid as may be best adapted to the construction of the boiler, without touching the sides thereof. After having thus made one or more 15 revolutions within the fluid the upper extremity of the pipe or flue passes out through an opening made for that purpose in the side of the boiler. The fire-place is to be so contrived that the flame, heat, and smoke, having been first applied to the bottom of the boiler, as usual, shall pass wholly off through this pipe or flue. This pipe or flue for conveying the heat through the fluid 20 may be made of any material that will stand the fire and the fluid, and have any form you please, but the purpose will be best answered by making it such that a transverse section thereof may be a thin rectangle or a very flat oval, that is, as far as may be from a circle, for by that means the heat will have the greater effect on the sides of the pipe, and so on the fluid. The 25 dimensions thereof must also be adjusted in proportion to the fire to be applied, and so must the number of revolutions that it makes. By this Invention two or more boilers may be heated with one and the same fire, which after operating on the bottom of the first boiler in the ordinary way may be conveyed into the second boiler, and thence into others through a flue 30 making revolutions therein, as in the case of a single boiler, or after the flue hath made one or more revolutions in the first boiler, without exhausting the whole heat, it may be continued successively to a second or more, till the heat is exhausted. This Invention might also be employed to receive the flame and heat of furnaces used in the smelting of all metallick substances by con- 35 veying such flame and heat through the pipes to heat the fluid in the manner before mentioned. By this manner of conveying the flame and heat through the fluid no part of the effect of the fire is lost, whereas in the ordinary way a great deal is lost. The fluid will not only be boiled in much less time, but
