Description: |
| This patent date, along with July 7 1863, is reported on a Pioneer No. 1 sorghum press made by James L. Haven & Co.
Sechler & Day succeeded the late firms of Hedges, Free & Co. & Watkin, Free & Co. ca. 1862.
Abstract:
My improvements consist in surrounding the openings for the roller or cylinder shafts in the upper and lower plates with annular ledges, which ledges are accommodated by corresponding recesses in either end of the rollers, while the faces of the rollers are permitted to extend downwardly and upwardly externally to the circle of the ledges to the top and bottom plates. The ledges on the bottom plate serve to stop the cane-juice from reaching and flowing out through the openings for the shafts, retaining the oil also from spreading and mixing with the juice. The ledges on the upper plate serve to prevent the oil from spreading along the lower surface of the plate to a point outside the area of the rollers and to a contact with the cane, while the recesses in the upper end of the rollers serve to contain the oil which escapes from the upper journals, permitting it to be conducted through the tube hereinafter described to the lower journals.
My second improvement consists in providing a regulator and adjuster, being an oblong throat placed longitudinally with and extending the entire length of the rollers, and of a Width just sufficient to accommodate as much cane as should be permitted to be fed between the cylinders or rollers at one time. The design of this device is also to adjust the cane as it is fed in quantities through it to the mill in a vertical array or series of stalks evenly distributed through the entire length of the crushing-rollers, preventing the admission of a quantity sufficient to clog or to endanger the mill, and securing, by an even distribution of the cane over the entire length of the rollers, their uniform action and an equal pressure upon all the substance passing through them. This regulator or adjuster is used, in connection with a table of suitable height and length, to support the outer ends of the stalks while they are being carried through the regulator to the mill, and in case the quantity presented to the rollers should at `any time by enlargement become greater than can be readily drawn through the regulator some stalks will be broken off and the amount of cane thus reduced to the proper quantity.
My third improvement consists in providing tubes for oil, passing down through appropriate openings from the recess in the top of the rollers to points of communication with the bearings below, by which the oil, after supplying the upper journals, is conducted to the journals below, and thence is permitted to distribute itself to the gearing, thus securing, by a convenient and certain process, the means of lubricating the remote and otherwise almost inaccessible parts oi the apparatus.
My fourth improvement consists in adapting a pair of corrugated cylindrical shells or sleeves, so constructed in their internal and external dimensions in reference to the diameters and central distances of one pair of the crushing rollers that they may be conveniently slipped over the latter and retained in place by corresponding lugs and recesses. The corrugated surfaces of the cylinder thus prepared match together in close proximity, and constitute, when thus arranged, a substantial, convenient, and efficient corrugated mill.
Claim:
Surrounding the openings in the top and bottom plates with annular ledges L, when employed in connection with rollers having recesses corresponding with them in their top and bottom ends.. |
