DANIEL L. DAVIS, OF HARVEYSBURG, ASSIGNOR OF ONE-HALF TO HARRISON GORDON, OF VVAYNESVILLE, OHIO.

CANE- SPEGIFIGA'IION formingpart of Letters Patent No. 246,731, dated September 6, 1881.

Application filed May 16, 1881: '(No model.)

To all whom it may concern:

Be it known that I, DANIEL L. DAVIS, of

Harveysburg,in the countyof Warren andState' of Ohio, have invented certain new and useful 5 Improvements in (lane-Mills; and Ido hereby declare that the follovvin g 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, refer- IO ence being had to the accompanying drawings, which form a part of this specification, and in which--.

Figure 1 is a longitudinal vertical section, and Fig. 2 is a plan or top view, of the ma- 15 chine, the cap or top, piece having been removed.

Similar letters of reference indicate corresponding parts in both the figures.

My invention has relation to sugar or cane 2o mills for expressing the juice of sugar-cane; and it consists in certain improvements in the cane-mill for which Letters PatentoftheUnited States No. 54,960 were granted on the 22d day of May, 1866, to Richardson, Howell, and the 2 5 undersigned, which said improvements will be hereinafter fully described, and particularly pointed out in the claims.

In the annexed drawings, the letter A represents the frame of the machine, which is pro- 0 vided with a' removable cap or top piece, A. B is the feed-table, which inclines in the direction of the fluted or corrugated feed-roller 0, between which and the table the cane is fed, the roller 0 operating in conjunction with a 5 lower feed-roller, O, of similar construction, placed under the roller 0. The rollers O and 0 feed the cane into the hopper D, which is provided with a set of steel knives or cutters, d 61, so set into the hopper as to alternate with 0 knives or cutters c e, which are arranged in parallel rows upon the circumference of a cylinder, E, which is journaled within the hopper D. This hopper has an open bottom, and its surface D nearest the feed-table and rollers O 4 5 and O is inclined downward toward the rotary platform, as plainly shown in Fig. l ofthe drawings, so as to form a deflector for a jet of steam projected through an aperture, f, in the apron F in the fore part of the mill, underneath the 4 5o feed-table. As the cane is fed to the hopper it is cut and split by the stationary knives (Z and the revolving knives of the cylinder E into fine strips, which drop down through the open-bottomed hopper upon a rotary platform, G, where they are met by the jet of steam in- 5 jected through the aperturef, and deflected or fed upon platform G by the inclined forward part or shield, D, of the hopper D. This platform is composed of a series of flat boards, which are hinged to one another, and arranged L so as to form an endless apron, with interstices between the sections, which is supported upon and carried by a series of suitably-arranged rollers, g, the upper ones of which are adapted to move upon the inclined ways G, and thus t permit of their engagement with and the carrying around of the apron by the sprocketwheels G This platform or apron is given motion by a sprocket-wheel, G and extends in an .upwardly-slanting direction to the rear 7c part of the machine; but its hearings or rollers g are so placed or arranged that they will carry the uppermost part of the apron against the under side of a pair of pressure-rollers, H andI, which arejournaled in spring-hearings 7 in the upper part of the machine, the springs exercising a downward pressure upon the rollers, forcing them against the platform or apron G as it passes beneath. them. The rollers g g, which carry this part of the apron, should be S placed so near together that they will effectually bear the apron up against the pressurerollers H and I without sagging, as itis at this point that the out and split cane is compressed and its juice extracted, which operation is fa- 85 cilitated by the jet of steam injected through the orifice f and deflected down upon the cut and split cane on the traveling apron or platform G by the deflector D, inasmuch as the steam heats and softens the cut cane, and thus c enables a more complete extraction of the saccharine juices.

At the rear end of the machine, underneath the pressure-apron G, is the bagasse or pomace carrier K, which is adapted to carry the bagasse n or pomace to any desired elevation outside of the mill or machine. Thejuice, as it is expressed between the platform G and rollers H and I, drops down through the interstices between the hinged boards or planks of the platform, and is collected in a pan or receptacle, L, placed below, from which it has a suitably-arranged outlet.

The arrangement and combination of the pressure-rolls II I and pressure platform or apron G insure a more perfectcompression of the cut and splitcane than where this is eifected by passing it simply between a pair of rollers, and at the same time the traveling platform G serves as a strainer for the cane-juice and effectually prevents any part of the bagasse from finding its way into the juice-receptacle L. The steam, which is injected into the machine through the aperture or orifice f, travels the entire length of the platform or apron G, passing underneath both of the pressure-rollers, thus keeping the rollers clean and free from bagasse, besides facilitating the extraction of the sugar or saccharine principle of the cane.

The several rollers, cylinders, &c., herein described, and which form parts of my machine, are provided with pulleys and cog-wheels on the outside of the frame, as shown in Fig. 2, which are suitably geared; but as this gearing may be effected in various ways, and as it forms no part of my invention, no necessity exists for describing it.

Having thus described myinvention, I claim and desire to secure by Letters Patent of the 30 United States- 7 1. The combination of the feeding-table B, feed-rollers G O, and cutting and splitting knives d 6 with the carrying-apron G, formed of hinged inflexible boards, sprocket-wheel G, 3 5 guides G, roller-bearings g, and the pressurerolls H I, as and for the purpose set forth.

2. In a cane-mill, the pressure-rolls H I, the endless apron or platform G, constructed and arranged as described, the fixed apron F, pro- 40 vided with a steam-inlet,- f, and the deflector D, constructed and combined as and for the purposes set forth.

In testimony that I claim the foregoing as my own I have hereunto afiixed my signature 5 in presence of two witnesses.

DANIEL L. DAVIS.
