CAN E-MILL.

SPECIFICATION'forming part of Letters Patent No. 480,522, dated August 9, 1892.

Application filed September 18, 1891. Serial No. 406.088. (No model.)

To all whom it may concern:

Be it known that I, DONALD SKEKEL, of Georgetown, in the county of Demerara, Brit'- ish Guiana, have invented a new and Iniproved Cane-Mill, of which the following is a full, clear, and exact description.

The invention relates to improvements in three-roller sugar-cane mills; and its objectis to provide a new and improved cane-mill which is simple and durable in construction, very effective in operation, and arranged to utilize the crushing power to the greatest advantage and without injuring the head-stocks.

The invention consists of certain parts and details andcombinations of the same, as will be fully described hereinafter, and then pointed ont in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation of the improvement. Fig. 2 is a sectional plan View of the same. Fig. 3 is an end elevation of the same with parts in section, and Fig. 4 is an enlarged face view of the guide for the corrugated turning-roller.

The improved cane-mill is provided with three parallel rollers A, B, and C, journaled in suitable bearings D, E, and F, respectively, held adjustably in the head-stocks G and G. The rollers A and B are the two top rollers and are arranged in a horizontal plane, as is plainly shown in the drawings.- The third roller C is located directly below the top roller A and forms with the latter the front or entrance rollers between which the cane is passed in order to crush the same.

In order to relieve the head-stocks G and G of the strain incident to the crushing of the cane, sets of horizontal bolts H are provided for each head-stock, the said bolts being U-shaped and extending horizontally in line with the bearings D and E for the top rollers A and B, respectively. The bolts H pass at their ends through the caps G2, ar ranged at the rear ends of the stocks, the nuts of the said bolts screwing against the said caps, as is plainly shown in the drawings. A second set of bolts I is arranged for each head-stock and ext-ends vertically at the sides 4 of the bearings D and F, serving to take up the strain incident to the crushing of the cane between the two rollers A and C, it being understood that the other bolts H take up the strain incident to the crushing of the cane between the rollers A and B. The upper ends of the bolts I pass through caps G3, against which abut the nuts of the said bolts.

In order to guide the cane upward between the top rollers A and B after the cane has left the entrance-rollers A and C, the corrugated roller J is provided, located in the rear of the entrance-rollers A and C and below the top rollersA and B. rlhe roller J is journaled in suitable bearings K, held in the headstocks G and G', so that the cane after leaving the front rollers A and C is pushed upward by the corrugated roller J to pass be tween the rollers A and B to undergo the l iinal crushing.

It is understood that the several rollers A, B, and C are geared with each other to rotate in unison. The roller J is also geared with the said crushing-rollers and in such relative proportion that the speed of the roller is equal to the surface speed ot' the crushing-rollers.

ln order to prevent the cane from passing to the bearings K of the corrugated roller J, guides L are provided, each bolted inside of one of the head-stocks, as is plainly illustrated in Figs. 3 and 4. Each guide L is formed with a segmental projection L', eX- tending over the end ot the corrugated roller J, as is plainly illustrated in Figs. 3 and 4. The top surface of this projection L is inclined upward and outward to prevent jamming of the cane. The under side of each guide L is formed with a semicircular offset L2, passing over part of the shaft of the roller J in front of its bearing K to prevent the cane from passing to the said bearing. The bearings F for the rollers C extend to the front side head-stocks G and G and can be conveniently removed to permit of removing the lower entrance-roller C without taking the machine apart.

It will be seen that by arranging the crushing-rollers in the manner described the juice pressed out of the cane is not liable to return into the crushed cane, as the said juice passes down over the roller J to a suit-able recepta- Lis IOO

cle located in the lower part of the machine. Thus the crushed cane which iinally passes upward from the rollers A and B is comparatively free from juice.

The roller J on account of being corrugated readily turns the cane upward to guide it to and between the rollers A and B.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A cane-mill provided with three crushing-rollers, of which two are the top rollers and are arranged in a horizontal plane, while the third is located under the first top roller and forms with the latter the front or entrance rollers for the cane to be crushed, a corrugated turning-roller arranged in the rear of the front 0r entrance rollers and below the top rollers, and the guides L, formed with upward and outward inclined integral projections L', extending over the ends of the corrugated roller, and with semicircular olsets L2, projecting between the ends of said roller and its bearings, substantially as shown and described.

2. In a cane-mill, the combination, with the head-stocks, of three crushing-rollers journaled in the said head-stocks and of which two are the top rollers arranged in a horizon-
