HENRY 'RAB/LEY, OF LOUISVILLE, KENTUCKY.

Letters Patent No. 87 ,288,datcd Fcbrua/ry 23, 1869.

` IMPROVE!) SORGHU'Ii/E-'l'U'ICtElv EVAPORATQR.

The Schedule referred to in these Letters Patent. and making part of the same- To all whom tt may concern:

Be it known that I, HENRY RAMEY, oi' Louisville, in the county of J eil'erson, and State of Kentucky,ihave invented a new and useful Improvement in Self-Skin1 ming Evapo'rators and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specilication, in which- Figure 1 is a perspective view of my improved selfskimming evaporator, and ofthe furnaeein connection with which it is used;

Figure 2 is a central longitudinal elevation, on line yfy oi'ig. 1; and

Figure 3 is a vertical elevation online of fig. 2.

Corresponding letters denote corresponding parts in the several figures. 1

This invention relates to that class of evaporator-s in which the juices containing saccharine matter are to be treated; and

It consists in the construction of such evaporator, whereby the scum, which rises upon Athe surface of the juice while being boiled, shall be allowed to pass oi from the pan or pans, and be conveyed to any desired locality.

A, in the drawings, represents the furnace, which mayt be constructed of sheet-iron, or of any other suitable material, and of any form adapted to the reception of the evaporating-pan D and the damper O.4

B is theuptake, through which the products of combustion pass from thefurnace to the atmosphere.

G is a damper, which is lplaced within that portion of the furnace which constitutes the iue, orpassage, whichleads from the grates to the uptake, and which is so arranged, with reference to a deiiecting or dividingplate, place horizontal-ly withinlsuch ue or passage,

that the heated prodncts'of combustion, in passing,

may be conducted above such plate, and in immediate-contact with the pan; or they may be made to pass entirely below such plate, and thus prevent the liability of burning the' srup at that point. D is an evaporating-pan, which is to be made of copper, or any other suitable material, andwhich has,

at its forward end, or that portion of it which is over.

the hottest portion ofthe furnace, two compartments, formed by inserting centrally therein the vertical partition-plate F, shown in iig. 3. lhese compartments are each provided with a cock, or valve, afby which the saccharine mattei' may be drawn from them into the shallow compartments of the pan, after it has been boiled,'and tosome extent neutralized' therein.

This evaporating-pan is also provided with a series of compartments, which are located in .the rear of those already alluded to, and into'which the juice is drawn from the first-mentioned ones,'for the purpose of being converted into sirup therein.

The divisionfplates F', which, together with the walls of the pan, constitute those apartments, are so arranged that the material, in passing from the front to the rear one, passes alternately under-'and through such parttions, those through which it passes being controlled by slidin g gates, or valves, in such a manner that the progress of the material trom one compartment may be controlled, and the same be returned, for alonger highly-heated portion of the pan.

Y E is a trough, or conduit, which is formed 'upon or attached to the upper and outer edge of the pan, which may be made ilaring for a short distance downward from such edge, said-trough being for the purpose/of receiving any overflow from such pan, 4and especially -for receiving the scum which rises while the juice is being boiled, and for conducting the same to any desired location.

Those` portions of the trough, or conduit, which surround the more elevated portions of the pan, may be provided with vertical pipes, for conducting the scum or overflow from such elevated portion into the trough,

' or conduit, which surrounds the lower portion of the pan.A

I have described my evaporating-pan as being made entirely of metal, but it will be apparent that its sides tom, in such a manner as to-prevent any leakage at such joints, if that form of construction should be preferred.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, isyThe arrangement of the conduits E E and vertlcal partitions F F, with reference to the bevelled flange stantially as shown and described.

In testimony whereof,I have signed my name to. this specification, Iin vthe presence of two subscrlbmg wltnesses.
