'In defecating and evaporating saccharine juice it is important that it shouldbe exposed tojheactio'n of heat asshorta time as is con,

sistent withits vnaturein orller to produce the best-results or to preventfinjury'to the sugar jin consequencepof a longapplication of heat l t0 it.'

The nature of my in-vention consists in so constructing and arrangingcellnlar or tubular boilers as to allow of a contiuuonsor intermit tent circulation of saceharin'e juice, and atthe same time toafford facilities for purifying the juice and reducing it to thedesired consistency- My invention furthe;l consists in providing for the application oftwo or more cellular or tubular boilers for evaporatin g sacch arine juice to a singlefurnace for the purpose of utilizing `heat,as will he hereinafter described.

To enable others skilled in the art to understand'myinvention, I4 will describe ils construction andoperation.

' In the accom panying drawings, A represents the'cellularvboiler, consisting oi' an upper comv partment, a, which is divided into chambers, or iu otherwords, which is subdivided by the ledgesa, forming a broad under ow or current ofthe juice, and a lower compartment, b, which l is divided into chambers or cells that are formed by crimping sheet metal into folds and then `closingup the alternate crilnps or folds, or by `forming a solid heading at one or both ends of V'the crimps. One ormore large finishing cells or chambers are formed to allow of a more free circulationof lthe thick sirop and to afford a convenient chamber for drawing oif the iinished sirup.

to that of the otherceils'.

The scum-trough dis for the purpose of rc! ceiving the scum as `it is carried by the foam in the direction indicated byth'e arrows in Eig. A

l, or any other foreign matter that may be in the juice, andthrown there. by the ebullition lover the cells.l Said trongh'is also forthe reception ot any chemical agent `that may beemployed'in the process of defecation.

The air or steam spaces a'and the liquid cells b may ,be/of `any desired width or depth required nondo I confine myself to any detinite shape ofcellular surface, as the corrugatons or ridges may be .made ot`- any desired form which may be found best adapt-,ed for the purpose. a A y The finishing-cells c and the-scumtrongh d may be arranged as represented, or'at any other point in the pan or boiler, or this trough may be dispensed with, and one lor more movable chambers substituted, and 'placed either on the inside or on the outside of the boiler, so as to receive nthe scum or dirt.

" I desire to employ one or more "stationary or movable ledges or gates placedin the cells,

`or arranged on top of the'air-chambers, for the l i purpose of controlling` the current of juice, which is allowed to llow underthe ledges, while the foam run'sgover the ledges. I also desire to employ one or more strainer-s, movable or stationary, placed in the cells or on top of the air-chambers; but I do not confine myi v The finishing chamber or chambers may be ofany desired size or proportion self to any particular mode of controlling the current, as it may bc an indirect ow, or the juice may be allowed to flow from one chamber to another by means of gates, -or the ledges maj be dispensed willi entirely and the juice allowed to tlow over the cells, and the current may be constant or allowed to run at intervals, at pleasure. u 1

rl`he drawings represent the boiler placed upon a portable furnace; but I do not conlne myself to any particular kind of furnace. In practice, provision may be made for elevating or depressing either end or side of the boiler.

1t is a good plan to use the boiler only in purifying and reducing cane-juice, butitmay be used in conjunction with any of the well-known evaporators or boilers. It is also a good plan to place a second boiler over the rst or lower boiler,as represented in Fig. 4, theuppcr boiler beingconstructed similar tothe lowerone, with an additional arrangement for conducting'the condensed steam or water away from the lower' boiler, whichconsists ot' a glitter or a partial bottom to the upper boiler, that may-serve as a retainer of steam as well as a gutter or trough. Thisarrangement' is for the'purpose of utilizing heat that would otherwise be lost. The condensed steam in the f'orm of water runs down the sides ofthe cells to the edges thereof, andthenee along these edges into the conducting-trough, which is represented in Fig.

5. The boiler B should be elevated on one side, so that its bottom will incline toward the trough g, above described.

Instead of employing the heat from a furnace to boil the juice, steam may be used advantageously with my boiler; or, if desired, the lower boiler ot' Fig. 4 may be used as 'a steam-generator for supplying heat to the upper boiler. r

In the operation ot' my boilers the juice is allowed to run iutothe Chambord of the lower .boiler until this chamber is suticiently full to allow the juice to foam over all the ledgese, when an active heat is applied to 'the boiler, the senin being carried by thejoam and deposited in thecharnbcr d, thefresh juicetlowing into the chamber d constantly or atvintervals,

as may be desired, while at the saine time an under-currentof purified juice flows toward the finishing cell or chamber c, from which the clear sirup maybe drawn o' when at the proper consistency for crystallization.

In Figs. l, Z and 4 I have represented a cover, h, applied to the boilers for the purpose vof confining the heat therein as much as possible, and also for preventing the action of air upon the juice. These covers are removable.

The tubular boiler is formed by means of a false bottom, C, (shown in Figs. 4 and 5,) which is applied beneath 4the cellular bottom of the boiler so as to close the air-cells a. This plate may be so applied that itlcan be conveniently removed at pleasure for cleaning or inspecting the cells. By means of such plate the cellular boiler is converted into a tubular boiler.

Having thus described my invent-ion, what I claim as new, and desire to secure by Letters Patent, is

1. The construction of cellular or tubular boilers, substantially in the manner and for the purposes described.

2. The combination of one or more perforated or imperforated ledges with cellular or tubular boilers, substantially ais and for the purposes described. n v

3. Constructing a tubular or cellular boiler ywith finishing cells or chambers, substantially as described. 4. The combination of two or more cellular or tubular boilers, arranged substantially as and for the purposes described.

5. The combination ot a lid or cover with a cellular or tubular boiler, substantially as described. j p

6. The construction of a celluar boiler' with a bottom plate, C, or its equivalent, substantially as described.

Witness my hand in the matter of my application for a patent for improvcmentin eellular or tubular boilers.
