Cane Mill
|
Henry B. Stevens |
Buffalo, Erie County, NY |
Abstract:
Our improvements are applied to vertical- roller cane-mills; and some of them consist in the adaptation to such mills of principles which have been secured to us in former Letters Patent by different arrangements to horizontal mills. These features are, first, wrought- iron strap-bolts around the bearing of the rollers; second, India-rubber springs or washers upon the strap-bolts to give elasticity to the main roller; third, the free removable scraper. The application of these features of invention to vertical-roller cane-mills has been attended with much difficulty, so as to derive from them advantages corresponding with those secured by their use in horizontal-roller mills. Thus, while it is a matter of comparative ease to make the rollers of horizontal mills adjustable with vertical mills, owing to their peculiarities of construction and action, the successful adaptation of self-adjustment to the rollers has been regarded as a problem nearly impossible to practically perform. This difficulty will be appreciated when it is considered that the power is applied directly to, the main roller, itself comparatively small, through a lever twelve or fourteen feet in length, and consequently a powerful leverage is exerted upon its bearings, thereby subjecting them to immense strain; and hence, though self-adjustment is all, the more necessary or desirable, yet it is much more difficult to apply the principle without disarrangement. Unless the canes are fed with great care and regularity, the mills frequently clog, and are very liable to break, without elasticity and self-adjustability; and since, in order to produce the requisite pressure, the rollers have to be keyed tip closely together in a rigid position, and all the strain, whether ordinary or excessive, from any special cause, has heretofore been resisted solely-by the cast-iron frame or housing which held the rollers, such material has furnished inadequate strength to avoid breakage; or, if the rollers are adjusted too far apart, they will not crush the cane sufficiently nor fully express the juice. This de- feet is increased in the vertical mills by the additional difficulty in feeding the canes regularly in the vertical opening between the rollers, the canes having a tendency to settle downward in a mass at the lower ends of the rollers.
Claim:
The turn-plate, constructed substantially as described, and arranged with its semicircular groove, and rod fitting therein, and the adjusting-screws, in combination with the minor rollers of the vertical cane-mill |

Abstract:
My invention relates more particularly to that class of cane-mills which are provided with two or three rollers arranged vertically. This class of cane-mills is very extensively used in cane-growing countries, and these mills are mostly constructed in a primitive and unskilled manner. The object of my invention is to render this class of cane-mills more durable in construction and more efficient and convenient in their operation.
Claim:
The combination, with the adjustable crushing-roller, of the bearings, ut, sliding in ways, a, the set-screws, p, passing loosely through the stationary frame, the springs, o, arranged on the set-screws, p, between the ways, az and the screw-nuts, q, applied to the setscrews, p, on the inner side of the springs, o. |

Buffalo, Erie County, NY |
Abstract:
This invention relates to certain improvements in that class of cane-mills which are composed of three horizontal rollers arranged triangularly, and has for its object to improve the construction of the turnplate which is located between the rollers.
Claim:
In a cane-mill, the combination of a turnplate having at its heel an enlargement provided with a square opening, and a square removable shaft. |

Sugar Cane Mill

Abstract:
The principal object of our invention has been to provide a device of this nature having an accumulator, preferably of a differential type, whereby the pressure exerted upon the pistons of the mill hearing blocks will be taken by a separate piston which is subjected to substantially constant air pressure.
Claim:
In a sugar cane mill having stationary and movable bearing blocks, the combination with the movable bearing blocks thereof, of an independent, stationarily-arranged housing cylinder for 5q each block, a movable piston in each housing cylinder cooperating with said block, and an independent hydraulic accumulator, said accumulator comprising two stationary cylinders, a piston for each of said accumulator cylinders, said accumulator pistons being coactively engaged when producing pressure, said accumulator cylinders having bores of different diameters, the smaller accumulator cylinder being connected to the housing cylinder in a closed oil system, the larger accumulator cylinder being connected in a separate, closed air system and having its piston acted upon by the pressure of the air in the air system, whereby the application of air pressure of predetermined amount on the larger cylinder will produce an application of greater pressure to the mill bearing blocks by means of the piston in the smaller cylinder, an air pipe connecting a suitable source of air supply with the air cylinder of the accumulator, a pneumatically- operated shutoff valve in said pipe, a branch pipe connected in said air pipe and having one end thereof open to the atmosphere, a pneumatically- operated air relief valve connected in said branch pipe, and emergency means connected in said air system to control the closing of said shutoff valve and the opening of said air relief valve, whereby pressure upon the piston of the housing cylinder may be instantly removed by release of pressure within said air system. |
