IMPROVEMENT IN APPARATUS FOR EVAPORATING SACCHARINE JUICES.

Specification forming part of Letters Patent No. 28,349, dated May 22, 1.860.

0 all whom, it may concern:

Be it known that I, A. O. CLEMENs, of Grain Township, in the county of Vyandot and State of Ohio, have invented new and useful Improvements in Sorghum-Evaporators; and I do hereby declare that the following is a full and complete description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a top view. ,Fig. 2 is a side view, and Fig. 3 is a longitudinal vertical section.

Like letters refer to like parts.

My invention consists in an improved con struction and arrangement of the firebox and smoke-pipes, in connection with a peculiar arrangement of the division of the pan.

In Figswl and 3, A represents the bottom of the pan, in Figs. 2 and 3the different level of the several sections being shown at B. The sides of the pan 0 rise above the bottom some eight or ten inches.- Each particular section of the bottom B is horizontal when the pan stands upon a level surface. These sections upon the upper side are divided into two parts by the partitions D D D D, &c., which run crosswise the pan. The first division, D, is placed about one-third of the distance from the first offset B, leaving two-thirds of the space toward the smoke-pipe at the end of the pan,and one-third of the space toward the offset. This partition has a gate, E, in the middle, which can be opened or closed at pleasure, for the purpose of allowing the sorgojuice to flow into the second division. The partition D is placed upon the edge of the first projection, and is provided with two gates, F, placed one at each end, so as to cause the juice to flow in a circuitous course, as indicated by the arrows. These partitions are placed in regular order upon the different levels, as seen at D" D D", D"has agate at each end, and D has a gate in the middle, &c., to the end of the series, the last partition, D, having a gate at each end, and is placed upon the edge of the offset B". The section A is provided with a spout, G, for drawing off the concentrated sirnp. Immediately beneath each diiferent offset is a distinct firebox formed by the several partitions H H H H H, as seen in Figs. 3 and 4.. These partitions, forming the several fire-boxes, do

not extend across from side to side of the pan, but areinterrnpted at alternate ends, as shown in Fig. 4, and indicated by the dotted lines in Fig. 1, the partition H being open at the end next the sn1oke-pipe-in other words, it does not extend entirely across to the farther wall of the fire-box. In like manner the partition II joins the farther wall of the firechamber, and terminates at little before reaching the front, giving a zigzag course to the draft from one to the other, as indicated by arrows in Fig. 4. The opening, however, in the partition H is provided with a damper, the handle of which is seen at I in Figs. 1 and 4., by means of which the draft from H" H H can be sent up the sm oke-pipe J; but by opening this damper and placing a cap, K, upon the top of the smoke-pipe J all the draft can be sent up the smoke-pipe L. Uponthe front side of the fire-chamber (which includes all the fire-boxes) are four doors for the introduction of fuel. These doors are seen at MN 0 1? in Fig. 2. M opens into the fire-box, next to the smoke-pipe L, the door N into the secondandthirdfire-boxes. ThedoorOopens into the fourth and fifth fire-boxes, and I opensinto thelastfire-boxintheseries. Vhen the damper I is closed, the draft from the fire box at. 0 will pass around the back end of the partition H, around the front end of the partition H and into the smoke-pipe J; but if the smoke-pipe J is closed by the cap K, and the damper I opened ,the draft will pass around the back end of the partition H in front of the partition II, and at the back end of II into the smoke-pipe L. By means of these doors upon the side of the fire-chamber a fire can be kindled in any of the divisions, and thus heat applied at any point along the whole series of divisions in the pan.

By placing the sorgo juice, when in its crude state, .in section A and closingthe gate E, heat can be applied under that part of the division occupied by the juice, and the scum can here be removed. Now, byslightly drawing the gate E, the juice, partly purified, will flow. into the division A, where a further purification and concentration will take place. The gates in the partitions D D may now be opened, a fire having been kindled under this ofi'set, where still further concentration will take place, and so on through the series; or the process can be discontinued in the first three sections and conducted in the last three by closing the damper I and removing the cap K from the smoke-pipe J.

In having the bottom of the pan composed of variable sections in regard to elevation, the juice, by being placedin the highest,will flow onward to the lowest,without .the necessity of tipping the pan, thus obviating a very incon venient practice where the whole of the bottom of the pan is upon the same level; In my arrangement of the gates a flow of j uice can be supplied tojust meet the demands of evapo ration. The scum that rises in each separate division will float upon the surface, and not pass through the gate.

I do not broadly claim either making the bottom of the pan in sections placed at different elevations, or the giving a circuitous flow to the cane-juice through the several divisions of the pan, or the giving a circuitous course to the draft; but I believe that my above-described sugar-evaporator is new and an improvement upon those heretofore known.

Having thus fully described my invention. what I claim, and desire to secure by Letters Patent of the United States, is

The construction and arrangement of the several fire chambers and the two smokepipes with the damper I, in combination with the peculiar arrangement of the pan in different divisions at variable heights, substantially as set forth, for the purposes described. I

A. G. CLEMENS.
