EVAPORATING-PAVN.

SPECIFICATION forming part of Letters Patent No. 517,765, dated- April 3, 1 8 94. Application filed October 16, 1893. Serial No. 488,317- (No model.)

To all whom it may concern.-

Be it known that I, SIMEoN ALEXANDER POCHE, a citizen of the United States, and a resident of Donaldsonville, in the parish of As cension and State of Louisiana, ha'veinvented certain newand useful Improvements in Evaporating Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in boilers for evaporating cane and other juice in the manufacture of sugar, andits object is to provide an improved construction of the same, whereby I secure superior advantages with respect to economyin fuel andefficiency in operation.

Theinvention consists in thenovel construction. and combination of parts hereinafter fully described and claimed.

, In the accompanying drawings: Figure 1 is a central longitudinal section of a boiler and evaporating pan constructed in accordance with my invention; on the line 00-05, Fig. 2. Fig. 2 is a cross section of the same.

. In the saiddrawings, the reference numeral 1 designates a cylindrical boiler provided with a series of fiues 2,in its lower part connected with the heads 3. These fiues can be of any number and size found convenient or desirable, five being shown in the present instance.

In the upper part of the boiler is a rectangular opening in which the evaporating pans 4., are located. Three of these pans areillustrated'in the drawings,but their number may be varied if desired, or circumstances require. These pans as shown, are formed of a rectangular box, projecting down into the boiler a sufficient distance through the opening therein, and are formed with outwardly flaring sides and ends 5' and 5", and divided by means of partitionsffi, into a number of compartments which constitute the pans proper.

Passing through these compartments are a number of steam pipes 7 which communicate with the steam space of the boiler, and the bottom of each compartment is provided with a draw off pipe 8, having acock 9. The upper edges of the partitions are formed with.

the pipes 7 which will result in the evaporization of the juice contained in the pans. From the above it will be seen that the pans themselves will not only be heated by the steam surrounding the lower part thereof, but the liquor contained therein will be heated by the pipes 7 passing therethrough, thus effecting a great economy in fuel.

Having thus described my invention, what I claim is In an evaporating apparatus, the combination with a boiler having an opening in its upper part, and provided with a series of fines, of the rectangular box seated in said opening, having flaring sides and ends, the partitions located therein having troughs in their upper edges and dividing the box into a series of compartments, the drainage pipeconnected with said troughs, the transverse pipes passing through said compartments and communicating with the steam space of the boiler and the ,draw ofi pipes connected with said compartments, substantially as described.

In testimony that I claim the foregoing as my-own I have hereunto affixed my signature.

in presence of two witnesses.
