IMPROVED SUGAR-EVAPORATOR.

Specification forming part of Letters Patent No. H, 195, dated January 12, 1864-.

To all whom it may concern.-

Be it known that I, R. S. COLE, of Mount Pleasant, in the county of Henry and State of Iowa, have invented a new and Improved Evaporator for Saceharine Liquids, &c.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 represents a longitudinal vertical section, the plan of section being indicated by the line 00 a, Fig. 2. Fig. 2 is a transverse Vertical section taken in the plane indicated by the line y 3 Fig. 3. Fig. 8 is a horizontal section of the same, the line 2 c, Fig. 1, indicating the plane of section.

Similar letters of reference in the three views indicate corresponding parts.

This invention consists in the arrangement of shoulders facing toward the fire at the bottom of the pan or pans-one at the end of each sectionin combination with a descending flue, in such a manner that the fire strikes those parts of the bottom forming the shoulders withincreased power, and the juice contained in the wells formedby said shoulders in the interior of the pan is heated quicker than the juice in the other parts of the pan, and thereby the scum is thrown up and separated with superior facility.

To enable others skilled in the art to make and use my invention, I will proceed to describe it.

A represents a furnace built up of brick or other suitable material, and provided with a door, B, and fire-grate C, from which a fine,

D, leads to the chimney E. This flue runs in a downwardly-inclined direction, so that the heat will be thrown with increased force against the bottom of the pan, which is placed on the furnace.

F is the pan, made in three compartments, G H I; or it may be made in three separate sections (or more) placed side by side. The compartments or sections descend from the fire-place toward the chimney, the highest or heating-pan being placed directly over the fire. The bottom of the pan F is provided with shoulders at b c, facing toward the fire, so that the heat strikes the same with increased power. By these shoulders wells d e f are formed in the interior of the several compartments of the pan, and the wells d e of the compartments G H are situated close to the partitions g h, which separate the compart ments or sections one from the other. Gates *5 j in these partitions open or close the communication between them.

The juice is admitted to the first or highest compartment from the supply-tank J, which is placed on the corner of the pan, as clearly shown in Figs. 1 and 3, and as the boiling proceeds it is gradually let down to the second. and third or finishing compartment. That portion of the juice contained in the wells (1 e f is exposed to a higher heat than the juice in the other parts of the compartments, and consequently the scum rises in said wells and floats toward the coldest part of the pan, where it can easily be removed. The first or heating compartment is furthermore partially cooled by the stream of fresh juice admitted to it from the supply-tank, and the separation of the scum is thereby further facilitated. The flue D is provided with an opening, 75, in its side under the second compartment of the pan, and from this opening a side flue, K, extends to the chimney. Dampers Z m n-one close behind the opening is in the flue D, one at the bottom of the chimney, and one in the side flue-serve to regulate the current of heat. If it is desired to throw the heat against the bottom of the finishing-compartment I, the dampers Z and m are opened and the. damper a is closed, and the heat passes through the main flue D to the chimney. If it is desired to cool off the finishing compartment, the dampers Z and m are closed, and the damper n is opened and the heat is turned through the side flue to the chimney. By these means the temperature of the finishing-compartment can be regulated at pleasure, and the boiling can be continued without interruption in the compartments G H while the molasses in the finishing-compartment is cooled off and removed.

I am aware that acombination of shoulders and partitions resembling mine is described in Letters Patent granted to D. I. Durfey, May 17, 1859; but in the said Durfeys apparatus the principal object of my invention is defeated by having the shoulders presented away from instead of toward the fire, and by using an ascending instead of a descending flue.

I am also aware that in A. S. Wilders apparatns to operate in the same way as mine.

plication, patented J nne 23, 1863, shoulders The combined arrangement of the fire-place presented toward the fire are employed; but 6, descending or diminishing flue D shoulders in this neither the descending flue nor a simia b c, depressions d cf, and partitions g h, all lar arrangement of partitions is employed in as herein shown and described, and for the combination with the said shoulders, and it is purposes explained. therefore impossible for the said Wilders ap- R.
