    Lloyd's Improved Furnace or Fire-place, the vessells containing the liquids to be heated, boiled, or rarified within the vessells containing the same, as also without by means of pipes or flues, and also in using certain kinds of pipes or flues therein, which could never before be so employed with effect; and the same, as well as all other pipes and tubes, by being applied according to my new method, are rendered more durable, 5 lasting, and usefull for the heating of liquids and raising steam than by any other method ever before practised or attempted; and further, my said In¬ vention consists of a stove or fire-place calculated to save fuel in and about the drying and kilning of malt and grain of all kinds, wool, and other materials, in a more regular and beneficial manner than by any other method ever before 10 attempted or done; and the way in which the same is to be performed, is ascertained and described as well by the Figures and Delineations hereunto annexed as by the descriptions and explanations herein-after set forth (that is to say):— ' As to fire-places and vessells for heating liquids and raising of steam for any 15 use or purpose whatsoever* I set out the bottom or fire grate in any proper common mode, according to the size, form, or shape of the boiler or vessell con¬ taining the liquid to be heated, or from which steam is intended to be raised. N° 1 shews the inside of the boiler, a, in that Figure describes, the inside pipe or flue; b, the point where the pipe is connected to the side of the boiler by pins 20 and screws or other proper fastnesses, from which point there is a communi¬ cation between the fire-place beneath, and from whence the flame and heat ascends into and passes through the said pipe, which is in like manner con¬ nected with the side of the boiler at the point c, from whence there is a com¬ munication with the outside flue, as at a in N° 2, which commences near or 25 close to the wall of the chimney or stack next the same, and proceeds through the said outside flue, and enters the stack or chimney on the opposite side thereof; thus it is obvious that the said inside pipe or flue is subject to the action of a small part of the boiler, and in one direction only it is possible to vary the situation of the connection of the said inside pipe to the boiler; but gQ as the connection with the side or end of the boiler next the chimney or stack, and at as little distance asunder as possible may be, is certainly best, as well for the preservation thereof as for the convenience of setting the boiler to work without the said inside pipe in cases of accident thereto (as herein-after de¬ scribed), I have therefore not noticed any such variations. The said inside gg pipe or flue is supported by chains or perpendicular mettle bars or mettle rods, in like manner as is used for supporting the bottoms of boilers, or by mettle bars from the sides of the boiler, or by both means, or any other proper mode. The inside pipe or flue may be of cast iron or other proper mettle or metallic
