IMPRovED PAN AND :FURNACL' roR EVAPORATING.

The Schedule referred to in these LettersiPatent and making part ofthe same.

Toall whom/it 'may confiera?4 4' 4 ,Be it known that I, LEWIS SCOTT, of Sinking have invented a new` and useful Improvement in Vaporizing-Ilurnace and Pans; and I do hereby declare tion thereof', which will enable thoseV skilled in the art to make and use the same, reference being had -to the accompanying drawings, forming part of this specifi- 'lhis invention relates to a furnace and an arrange-` in the process of making sorghum sugar or molasses,

The invention `consists in the peculiar construction and Varrangement of the pans and furnace or stove, Vwhereby the contents of the pans are protected from undue heat or bui-ning, and whereby the stove or furnace is adapted to ordinary cooking-purposes, as will hereinafter be described.

Figure 1 is a vertical section of a furnace for vapof the process, the section being through the line x x of' fig. 2. Figure 2 is a top or plan view. i

Figure 3 is a vertical cross-section of lig. 1, through the line y y.

Figure 4, sheet 2, is a vertical longitudinalsection represented in sheet l, but with the pans a'rnnged differently, and designedto be used in perfecting' or finishing the process of vaporizatiom'the section being through the line z zof fig. 5.

Figure 5 is a sectional tcp view of the same, the front part being broken away to show the interior of one of the pans, and the' back or left-hand portion being aview from the line-z' z of iigjl.

Figure 6 is a vertical section of one of the pans, through the line y' yf of fig. 7.

`Figure 7 represents a broken section of a perforated bottom pan. i

Similar letters of reference indicate corresponding parts.

The views given on the two sheets of drawingsl are designed to representbut a single furnace, the second being a modification adapted to 'thel finishing-process, but provided with a detachable oven, to be used when the stove is inuse for cooking-purposes.

A represents the furnace, or stove, whichis Inade of metal, and placed on legs, and arranged otherwise i B is the upper pan, wherethe process of .Vapor-ization 1s commenced.

C represents a-pan,ivhich is placed directly over the fire-box of the furnace, into which the liquid from the upper pan is drawn, through the tube d.

Toprevent the liquid in thepan B from burning, a

double due is' provided for theproducts of combustion.

e is a horizontal partition-plate. in the fire-flue, placed directly under the pan- B. f isa iap-damper-at the front end of the plate e.

As seen inthe drawing, the heat -and products of combustion are allowed to come in contact with the bottom of the-pan, but by raising the damper, the flue g is closed, and the ue h is opened, and the heat "will pass, beneath the partition.

.Upon each side'ofthe re-box I there Aare cleats L or projecting ribs, i i, and

J is a shallow' pan which contains water, and rests upon the cleats t'.

By this means' the contents of the lower pan C are prevented from burning when'such protection is necessarv. v

'lhe finishing-pan J', represented in fig. 4, isdouble, thelower portion, k, being designed for water for the protection of the contents of the upper pau, there' being a space under andaround the sides, for water, so thatin finishing the sirup, it is placed iu a waterbath, where4 the temperature cannot rise much, if any, above the boiling-point. f'lhe lower pan k receives hot'water from a boiler, L, on the back part of the stove, through the pipe m.. j The steam which may be generated may pass out through the pipe n, or pass into the pipe o, in the pan. J, and be discharged from the end of thatpipc at p.

The top or cover of thepan J' is perforated for the purpose of retaining thedxeat, to some extent, while the vapor isallowed to escape freely.

' The pan represented in figs. 6 vand 7,'is designed for cookingfruit or vegetables, its bottom as well as top being perforated.

For boiling-purposesor common use, the finishingpan J may b removed, and the pan lc'only used.

All the pans may be removed, and the top of the fiu'nace may be covel-edwithplates, having the ordinary cooking-apertures, when the furnace is not used for vaporizing-purposes.

R represents the oven, which is double, with a flue passing around andbetween theparts, asseen in the drawing.

The vaporizing-pans shown inv fig. l--are constructed with metal bottoms with wooden sides, as seen in the drawing at S, but I do not confine myselfto that method, although, when the pans are/made, on a large`
