  • Patent number: 5544575
    Abstract: Apparatus for shelling seed corn in a manner which minimizes damage to the individual kernels includes a generally closed housing open at the top to receive ears of corn and having lower apertures for discharging the corn cobs to waste and recovering the kernels extracted from the cobs. Disposed within the housing are a pair of vertically aligned arrays of rollers, with the pair of roller arrays horizontally spaced from one another. Ears of corn are deposited through a slot in an upper portion of the housing and pass between the two arrays of vertically aligned rollers. The horizontal spacing between adjacent, horizontally aligned rollers in the first and second arrays of rollers decreases in proceeding from top to bottom, with the spacing between the two uppermost rollers being such as to easily allow an ear of corn to pass therebetween and the spacing between the bottom pair of rollers being essentially equal to the diameter of a corn cob.

  • Patent number: 5126679
    Abstract: Apparatus for testing shelled corn in a combine storage tank during harvesting includes a plurality of charged electrodes each in the form of an elongated rod arranged in a spaced manner and positioned in a lower portion of the combine storage tank to be completely encompassed by the shelled corn. The electrodes are coupled to a moisture meter located in the combine cab allowing the operator to determine the moisture content of the corn crop at harvest. The moisture meter is easily disconnected from the electrodes and removed from the combine to permit moisture testing of corn kernels while still on the cob prior to harvest.

  • Patent number: 4954783
    Abstract: A corn moisture tester is adapted to measure the moisture content of corn kernels on an ear of corn. The ear of corn may be affixed to the corn stalk. The device includes an ear cradle, a pair of electrode blades and circuit for measuring a moisture-dependent electrical property of the corn kernels. The cradle is adapted for receiving an ear of corn and includes two portions hinged together so they may be opened to receive the ear. When the cradle portions are closed, they form a substantially cylindrical interior cradle surface for engaging the ear of corn. The conductor blades are mounted to one portion of the cradle to pierce the kernels but not the cob when the cradle is closed about an ear under test. The electrical property measuring circuit generates and displays a signal representative of moisture.

  • Patent number: 4399973
    Abstract: A stand (10) for supporting a Christmas tree (12) having a trunk (14) with a butt end (16). The stand includes a base (18) having an upwardly opening tree well (20) adapted to receive the butt end (16) of the trunk (14). The base (18) also has an upwardly opening support post well (34) and a support post (28) adapted to be rigidly engaged in the support post well in unturning relation in an upright position. A trunk brace (36) has a multiplicity of support post holes (40) adapted to slip over the end of the support post (28), to engage it in unturning relation. The support post (28) is adapted to so engage the sides of the support hole (40) through which it extends as to support the trunk brace (36) at a selected distance above the base (18) in rigid, unturning relation with respect thereto. A retention band (42) is adapted to bias and retain the trunk (14 ) against an engaging surface (38) of the trunk brace, securing the tree (12) in the stand (10).
