'TO ALL WHOM IT MAY CONCERN:

Be it known that I, N. EVINGER, of Terre Haute, in thecountyof Vigo, and State of Indiana, have invente'd a. new and useful Improvement in Evaporators and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art tomake and use the same, reference being had to theaccom'panying drawings,'forming part of 'this specification, inwhich- 4 Figure 1 is a top or plan view of my improved evap'orator, part being broken away to show the coustruction.

Figure 2 is a detail scctional View of the same taken through the lineflx a', fig. 1.

' Similar lett'bf reference indicate corresponding parts. i i

My nventionvhas for its 'object to furnish an improved apparatus for evaporating cane or other saccharine juice, for the/manu facture of molasses and sugar, and it consist'sin the construction, combination, and arrangement of the various p'arts as'hereinafter more fully described. i

A is the furnace, which is made with three separate fire-chambers, a a and a The main fire-chan'ber, a has its grate in its forward end, and its 'ear partis divided by a'partitiou, as shown in fig. 1, se that the flame, smoke, and other products of combustion may pass back to the rear end of the said furnace-chamber a then turmand pass back to near the middle of said chamber, where it passes out into the chimney B, being all theitime directly beneath the boiler or pan C.

' The parts a and a of the furnace are placed, side by side, at the side of the part a 'and the products of combustion pass from them directly. into the chamber a from which they escape, in the manner hereinbefore described. i v

The lower part of the r'ear end 'ofthe chamber a is partially filled up, as shown in fig. 1, so as to contract the fiue and keep the hot products of combuston close to the bottom of the pan or-boilerC. i

The pan or boiler C is made deep and large enough to cover and fit upon the top of the part a of the furnace A, and is provided with a stop-cock, D, through which the juice, at the proper time, can be drawn ofl'into the -other'pans. i i' The inner mouth ot' the', discharging-opificc, in which the cock D is placed, is covered with a semi-tubular cover or cap, E, having an opening in its forward side, through which the juice passes to reach the dischargingorifice The discharging-orifice is also cover-ed w'ithasemi-conical strainer, F, nttached to asliding gate, G, said sliding gate having an opening in its lower end, corresponding in position with the said dischargigprifice. This enables the sti-einer to be removed, when desired, for cleaning or other purposes.

H and I are two shallow pans,' placed 'over the parts i"' andwt of the furnace, and which are provided with `handles at their sides and one end, as shown in figs. land 2.' I

J is a frame or rock, placed at the front of the partise and a for couveniencej shifting and emptying the pans H and I.

'K is the hand-book, the-lower'end of which is -forkeh and has a" hook fo'rmed upon the end of each of its two branc'hes, so that the positions of the pans H andI may be shifted upon the furnace readily and safely by taking hold of one oi' the handles o'f said panswithithesaid hook.

Insiug the evaporator, the juice is allowed to flow in a. continuous stream from the cane-mill, or from a suitable reservoir, into the deep boileror pan 0, where it is slowly boiled, causing the scum to rise and the guu and other sediment to settle. i

i When sufiicientl boiled, it' is drawn oif, throughthe cock D, in to the panH.

When it is desired that the juice should g-anulate, the cappr coverE is used,` whichikeepsback the gum and other sedinent that would prevent or retrd granulation.

The juice, when in the pans H and I, is boiledmuch more rapidly,'as. there is now no dahger of it scorching or burning. V i v V When the juice in the pan I is boiled down sufliciently, the said pan, by means of the hand-hack K, is drawn from the' furnace upon the frane or reck J, where it is tlted, and the sirup or molasscs poured out.

The pan H is then drawn frou the part a of the furnace to the part a and the pau I is placed upon the part a to receive another supply of j ce from thepau or boiler C, in the manner hereinbefore described.

I claim' as new, and desire to secure by Letters Patent- '1. The furnace A, constructed in three parts, a a a a'nd arranged. substantally as herein shown and described, and for the purpose setj'orth. i, I

. 2. The combinaton of the three pnns or boilers G, H, and I, constructed as described, with each other and with the parts a a a? of the furnace A, substantially as herein shownand described, and for the purpose set forth.

3. The straining-device, constructed as described, of the sliding gate G, carrying the semi-conical streiner F, enclosed by the semi-tubular cover E, all arranged iu -relation with the faucet D and side of the pan C, as

herein described, for the purpose specified.

4.' The combinatiou of the frame or rack J with the parts a? and *a of the furnace A, and with the pans H substantially as herein shown and described, and for the purpose set forth. I

5. The hand-book K, constructed substantially as heroin shown and described', when used in connecton with 'the pens H I, as and fer the purpose set forth.
