ELIJAH F. RESER, OF ORONOGO, MISSOURI.

COMBINED FURNACE, BOILER, AND EllAPORATlNG-PANS.

SPECIFICATION forming part of Letters Patent No. 309,096, dated December 9, 1884-.

Application filed August 25, 1884.

To all whom, it may concern:

Be it known that l, ELIJAH F..REsnR, a citizen of the United States, residing at Oronogo, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Combined Furnace Boil- .manipulating sugar-bearing canes and the sirups thereof; and it consists, mainly, in the peculiar arrangement of the evaporating-pan, the steam-generator, and the heater,whereby the latter suffices to generate the steam for driving the cane crushing machine, (not shown,) and for heating the evaporating-pan.

It consists, further, in certain details of construction, as will be hereinafter more fully described and claimed.

In the drawings, Figure l is a plan View; Fig. 2, a side elevation Fig. 3 is a vertical longitudinal section of the furnace, evaporating-pan, and boiler constructed according to my invention.

The side plates or castings areformed alike, and are connected at their forward ends by the front plate, 13, and at their bottom edges by the grate O and flue-plate D, the latter being extended horizontally from the rear edge of the grate rearwardly to the back of the framing under the uptake or smoke-stack E,

in which I arrange a damper, E, for the purpose of regulating the draft and heat. The flue-plate next the grate is deflected upward, and extends thence about parallel to and near the upper edge of side plates, A, so as to contract or reduce the vertical dimension of the horizontal flue D, in order that the heat therein may better act on the evaporating-pan F, which is placed over and forms the upper wall of the said flue, as most clearly shown in Fig. 3. The flue D extends the full width of the space between the side plates. Thus the heat comes in contact with the entire bottom of the pan, and acts thereon in a more effective man (No model.)

ner by reason of the contracted vertical area of the flue before referred to.

I The grate 0 may be of any desired construction suitable for the purpose, and I provide the front plate, B, with doors B B suitably disposed to permit the firing of the furnace Gor the removal of the ashes. The boiler G is arranged between the forward ends of the plates A, above the furnace O, and preferably of alength about equal the length of the grate O. I preferably form this boiler with an offset or chamber G, depending from its rear side into the furnace G, and provided with fire-tubes G", for the purpose of facilitating the generation of steam.

In order to firmly and securely retain the boiler in place I lap the upper edges, a, of the plates A on opposite sides of the boiler and conform same thereto, as shown in Figs. 1 and 2, whereby the boiler will be firmly braced and held to its place. This lapping of the side plates on opposite sides of the boiler also serves to retain the heat therein, and consequently enables the keeping of a proper steam-pressure with less heat than would be otherwise necessary. A suitable pipe, 9, conducts the steam from the boiler to the engine driving the crushing-mill, which engine and mill are arranged in close proximity to the boiler, and may be of any approved pattern. Illustration and detail description of said parts seems unnecessary. The evaporating-pan F is preferably removably seated on the plates A A over the flue D, and between the boiler and the uptake. The bottom of the pan is divided by transverse partitions f, extending alternately from opposite sides of the pan almost to the other side,leaving spaces f, connecting the adjacent divisions. By this construction the sap is caused to flow from opposite sides of the pan back and forth from the point where it is fed into same by pipe II, leading from the crushing-mill to the discharge h, thoroughly evaporating same, as shown. It will be noticed that the forward end of the pan is over the hottest portion of the furnace,

and is subjected to the greatest and an intense heat.

Experiment and practice have demonstrated that as sorghum and similar saps advance from one stage to another less heat is required to raise them to a boiling-point. It has also been found that the discharge end of the pans,

- where they are subjected to a uniform heat,

because of the excess of heat at such points will scorch and burn the sap. By my arrangement it will be noticed the sap is subjected to the greatest heat at the point where first fed into the pan, and the degree of heat to which the latter is subjected gradually decreases ,toward its discharge end, thus giving uniform and satisfactory results.

By my convenient arrangement it will be seen I, by means of the same furnace, genearranged over the lateral flue, and a steamgenerator arranged over the furnace, all arranged substantially as and for the purposes specified.

2. The herein-described improvement in evaporators,consisting of the plates AA, connected at their forward ends, and provided with a grate, C,'forming a furnace, C, the steam boiler or generator arranged over the furnace O, and having the upper edges of the plate A lapped on and conformed to the op.- posite sides thereof, flue D, extended horizontally from the furnace, with its upper end approximately flush with the upper edge of plate A, the uptake arranged at the rear end of said flue, and the pan mounted on the side plates over the flue D, and extending between the boiler and the uptake, and having its receiving end arranged next the boiler and furnace, and its discharge end next the uptake, substantially as set forth.

In testimony whereof I- affix my signature in presence of two witnesses.
