IMPROVEMENT lN SUGAR-EVAPORATORS.

Specification forming part of Letters Patent No. 40,934, dated December 15, 186-.

To all whom it may concern.-

Be it known that I JAMES HIGH, of \Val nut Fork, in the county of Jones and State of Iowa, have invented a-newand Improved Evaporator for saccharine Liquids, 850.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a longitudinal vertical section of my invention. Fig.2 is a transverse vertical section of the same. Fig. 3 is a plan or top view of the same.

Similar letters of referencein the three views indicate corresponding parts.

This invent-ion relates to evaporators pro vided with a transverse track at the rear end of the flue, in combination with two wheeled pans and with a stationary heatinpan in such a manner that the juice after it has been boiled in the heating-pan and freed fromscum can be conveniently ladled over into either of the wheeled pans and exposed to a moderate heat over the rear end of theiiue, for the purpose of finishing the sirup, and that one of said wheeled pans 'can be emptied while the contents of the other are finished.

The invention particularly consists in the use of wheels mounted on the sides in such a eight (more or less) compartments by means of transverse partitions a, with openings at opposite ends, so that the. juice is compelled to pass through the pan in a zigzag channel,

and that in its passage from one side of the pan to the other, whenever it reaches the middle or hottest portion of the bottom, the scum rises and is thrown toward the sides,\vlre1-e it can be readily removed. In this manner the juice is perfectly freed from all scum and other impurities, and the clear juice collects in the last or eighth compartment. From this compartment it is ladled over' into one of the pans D D, which is provided with wheels 1), running on a track, E. This track is secured ontherear end of the furnace A, and it we tends in a lateraldireetion over both sides of the same far enough to permit of moving either of the pans D D over the rearv end of the flue B. A curved shield, 0, which rises from the rear end of the pan 0, and extends over the edge of the pans D D, prevents the loss of juice during the ladling operation.

The pans l) D may either be made so that they form two eompartin'rents of one and the same pan, or they might be made separate and placed side by side. During the time one of these pans is over the fine in order to finish its contents, the finish ed sirup can'be convenient] y drawn from the other pan, and vice versa, so that no time is lost.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination, with the finishing-pans D D, mounted on wheels attached to their sides, as herein shown and described, of the guard 0, supported on either the stationary or moving pans and projecting over the space between the two,'iu the manner and for the purposes specified. JAMES HIGH.
