IMPROVEMENT IN METALLIC FABRICS FOR SMUT-MILL CASES.
Specification forming part of Letters Patent No. 140,] 99, dated J une 24, 1873; application filed November 26, 1872.
To all whom it may concern:
Be it known that I, HERBERT S. J EWELL, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Grain-Cleaners, of which the following is a specification This invention relates to the construction of the case of smut-machines and other graincleaners, whereby the extent of rubbing-surface will be increased, and there will be a slight elasticity that serves to lessen the wear upon the case, and prevents particles being wedged into such surface and remaining. The metal employed in such case is safely made of very thin plates or strips, so that the edges will not wear blunt, but will retain their sharpness until worn out. I make use of sheetmetal plates or strips, corrugated transversly, or slightly diagonally, and these are placed together and supported by cylindrical or segmental heads, such. plates being placed radially to the cylinder, or nearly so, and parallel to the axis of the fan or beaters. These corrugated plates are placed so that the corrugations bear against each other at the highest points, leaving openings somewhat like a honey-comb. The air, dust, and line particles pass away through these openings. When nat plates are introduced between the corrugated plates, the interstices are lessened with the same size of corrugation, by being subdivided, and there is a larger extent of cleaning edges presented to the grain.
1n the drawing, Figure 1 is a partial elevation of the cleaning-case plates, with the rings in ection and Fig. 2 is a plan of the case-ring and some of the plates. The rings a a are made either whole or segmental, and bolted logether. Within the surfaces of these rings re recesses for the receptionof the ends of he cleaning-plate, and the rings or segments are connected by columns or stay-rods c. The plates e e are corrugated transversely or at an inclination, and packed together as shown, so that the corrugated portions touch each other, leaving interstices, as shown at the portion A of Fig. 1. The depth of the corrugation becomes a gage for the size of with great efficiency in throwing the grain back into the revolving brush or fan.
The plates are self-sharpening, on account of being quite thin, and they wear but little, in consequence of their slight elasticity, and the great extent of surface formed by the edges of the plates renders the cleaner rapid in action and durable.
Care is to be taken that the length of the plates between the rings is not too great, otherwise the plates may spring out of place, if very thin. This, however. may be avoided by perforatiiig the plates and threading them upon a hoop, or by hoops around the outside of the circular range of plates, such hoops be ing applied at suitable distances apart.
I claim as my invention 1. The metal-plate e, corrugated transversely, and sustained by rings to form the case of a grain-cleaner, substantially as set forth.
2. The corrugated metal plates applied between and combined with straight plates to form the case of a grain-cleaner, substantially as set forth.
Signed by me this 19th day of November, A. D. 1872.
HERBERT S. JEWELL.
