` Leners Patent No. 87,858, ma Mwah 16, 1869.

IMPROVED PROCESS OP EXTRACTING SACCHARINE JUICES FROM CANES.

The Schedule referred'to in these Letters Patent and making part of the same.

To all whom 'it may concern:

Beit known that I, HORATIO S. LEwrs, of Chicago, in the county of Cook, and State of Illinois, have invented va new and improved Process of Extracting Saccharine Juices from Caneyan'd I do hereby declare that the following is a full, clear, and lexact description thereof, which will enable others skilled in the artto understand the same, reference being had to the accompanying drawing, forming part of this speciiication.

The figure is a vertical section of the tank, by means og which my improved process is carried into practical e `ect.

My invention has for its object to furnish a simple, convenient, and effective means by which the saccharine juices may be conveniently, eiectually, and thor'- oughly extracted from sugar-canes, sorghum-canes, &c., in such a way as' to remove all the sugar from Said canes, whether it may be in the form of sap, or juice, or whether it mayhave become crystallized in said canes; and

It consists in the process hereinafter more fully described.

A represents a tank, made of any suitable material, and similar, in construction and arrangement, to the ordinary lard-trying tanks.

The tank A is provided with a perforated false bottom, B, which I prefer to make in two parts, hinged to each other as shown in the iigure, for convenience in cleaning out the lower part of the tank, should it become choked up with refuse which may find its way through the perforations of the false bottom B.-

C and D are the pipes through which the steam is introduced into the tank A.

E is the pipe through which the extracted juices and G isan opening in the side of the tank A, through which the refuse is removed, and which is closed with a steam-tight door.

The cane is cut into lengths of about afoot, and placed in the tank A, through the man-hole F.

The length of the pieces into which the cane is cut is immaterial, but when about a foot long` they may be more conveniently placed in and removed from the tank, and will pack closer, allowing a larger quantity to be placed in the tank and operated upon at a time.

When a sui'icient quantity has been placed in the tank A, steam is admitted into the lowerpart of said tank A, through the pipe C, until the whole mass of the cane has been thoroughly heated. The pipe C isI` then closed and the pipe D opened, admitting the steam into the upper part ofthe tank A at the same time the pipe E is opened, allowing the extracted juices and condensed steam to iiow oii, the steam allA the' time iiowing in through the .pipe D. Then the sugar has all been dissolved out and extracted from the cane, the steam is shut off and the refuse removed through the opening G. The tank A is then ready to receive another charge. The juice thus extracted is then evaporated in the ordinary manner.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patentl. The process of extracting saccharine juices from canes by steam, substantially as herein shown and described.

2. Extracting saccharine `juices from canes by steam, whether under orwithout pressure, substantially as herein shown and described, and for the purposes set forth.

The above specification of my invention signed by me, this 21st day of November, 1868.
