To ALL WHoM'Ir MAY, conc/Eau:

Be it known that I, THRENGE BOUTT, 'of New Iberia, in the parish of St. Martin., and State of Louisiana, have 'invented a certain new, useful, and improved Furnace forthe Eva-porationof Cane-Juice, and mode of setting sugar-hotties vthereon-tand I do herebyzdeclar'e the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part`of this specification, in which- Figure 1 is a longitudinal sectional vie'wf and i Figui-e 2 a cross-section through th'o line a: :c of fig. 1. p

My invention has for flits object to reduce the consumption of fuel in,theoperation of making sugar, and at ,l the same time to bring about a more rapid heating and evaporation of the cane-juicein the process of its reduction to sirup than has heretofore been effected, or than can be effected with any existing arrangement; and it consists of a consolidated metallic furnace and 11de of novel construction and arrangement, conjoined with a. -new method of setting the sugar-kettles in the furnace, the whole constituting a portable apparatus which may be readily transported from plantation to plantation, if it should `be found desirable to, use it upon more than one. All existing arrangements are immovable, and hence the vsamekettles can only be used in the evapora-f tion of the `iuice that has been expressed from the'cane grown ou theplantation ou which the furnace with which said kettlesare connected islocated, which, it may be mentioned, is one among other reasons why men -of small `means cannot engage in the culture of sugar. y I

But my invention will be better understood by referring to the drawings, on which the same letters denote the same parts in both gures.

A is lthe furnace proper, which is constructed entirely out of metahand of cylindrical form. It may be made of sheet iron, and hence a section of un old and (for its original uses) worthless steam-boiler will answer for it, so that it can belnade at ivery small cost. Near the front end, which is closed either by'a xed or removable head, B, a series of transverse openings or narrow slots, a, is cut through Ithe bottom of the furnace A, to establish a grateon which to build the/fire. Upon one side of the furnace, and `just opposite the grate, is a hinged door, C, through which the fuel is thrown into the furnace. Through/the top of the furnace Alarge openings are made to receive the kettles D, which are inserted into them, as shown at both the gures. These openings conform to the form or shape'ofv the lrettles, in 'order that a tight joint may'be made at the point of contact of the latter with the edges of the former. i On top of the furnace A, andl covering something more than one-third ofthe circumference of the same, is placed 4the return-flue E. This flue is divided by the kettles into' two`couduits, F, at all points that lare opposite to them, but yet it is practically but a single Hue at every pointjbetween the kc'ttles, in consequence of the open spaces G, sothat it will be perceived a complete envelop 'ment of every kettle by the ame is insured in the {iue E, as well as inthe furnace proper below. The open space H connects the furnace A with the flue E at the. rear ends of both, th said space being covered by the arched apron J, as shown at fig. l. vThe flue E is curved at its sides, as shown at tig. 2, but it is fiat uponits top, whereit is perforated with as many apertures as there arekettles inthe collection or system, that arejust large enough to permit the kettles togo 4down into them until the flanches that project around their tops rest upon the upper surface ofthe Hue E, as shown at both figures. It will of course be understood that the centres of the apertures iu the top ofv the'ue E are exactly over therentres of' the apertures 'in' the top of the furnace A, for otherwise no perfect .adjustment of the kettles in these apertures4 could be effected. The drawings exhibit four kcttles in connection with the apparatus, but a greaterfor smaller `number mayvobvio/usly be used. A metallic smoke-stack or chimney, L, is connected withv the Hue at the front end of' thevfurnacc, whichmay be provided with a damper if the same shall he found to b e necessary, or a damper may be: placed in the flue or furnace. On the bottom ofthe furnace A, one atfeach end of it, are attached two legs or supports, K, upon which the apparatus stands, so that there is always some space between the said bottom and the ground or foundation'on'gwhich the furnace is placed. To prevent loss of heat from radiation, any proper envelopment of the furnace may be adopted. A teml L por-ary structure of bricks and mortar willanswcr every purpose, and,as I have demonstrated by actualpractice, it may be put up in a few hours and at very -slight cost. I have found, in factthat a sufficient covering may bc made with three thousand bricks, whcreasmo other existing sugarskettle furnace can. be constructed apparatus, as and for the purpose set forth.

tassa 0 with less than from twenty to thirty thousand. The kettles used in connection with my furnace-arrangement mayall be oi' the same size, or they may be graduated from the largest to the smallest size, as 'shown (upon a reduced scale) on the drawings, which, in my opinion, is the very best arrangement; or they may vary in size in any way to suit the fancy of the builder, or he whollas it buil- So also the'kettles may be of any formround, square, hexagonal, or otherwise. I reserve the right to use any form or description of kettle that is in .common use. y

The operation of inyinvention is so obvious that no particular description thereof need be given. It will be suicieut to say that the juice 'is put into the kettles and-fireinto the furnace, and that by the action of the latter the juice is evaporated orreduced to sirup, and' made ready to he transferred to the'inishing-pans in halfgthe time, and with a. consumption oi ,half the fuel that is required in the best existing evaporation-furnace of which I have any knowledge. y'This I have demonstrated by repeated trials.

The economy of timeand fuel'involved in the use of my invention isnot the only` merit or virtue to which it can lay claim. It is portable, and hence 'after it has performed its work in any given locality, by simply putting it on truck or other wheels, it may be I easily transferred to another, and -then to another, and so on indefinitely, and so do the work of several sugar-planters, who, not able separately to own an apparatus, may jointly readilydo so.

Havingthus described my invention, what I claim, and desire t9 secure hy Letters `Patent, isA

The furnace A and ilue E, when theseparts are severally constrncted,united, and operate as herein described, in combination with the" kettles D, when the whole constitutes al portable cane-juice evaporating- ',THRENGE BoUTr.
