  • Patent number: 4383583
    Abstract: A subsurface soil sampler constituted of a hollow tube having a pointed closure at its lower end for soil penetration and a handle at its upper end for manipulation of the sampler. A combined footrest and penetration limiter is detachably secured at a vertically selected position on the tube enabling application of the user's weight to soil penetration to a selected depth. The tube is provided with a lateral opening adjacent its lower end that is partially bounded by an outwardly offset lip for cutting and diverting a specimen of ambient soil into the tube on movement of the tube such as to advance the free edge of the lip into the soil. Species are disclosed with tangentially and vertically directed lips respectively operative to sample on turning and vertical movement of the tube. A ladle is provided for removing the specimen from the tube. One form of the ladle includes a valve element such that the ladle can be selectively positioned to close and open the lateral opening.

  • Patent number: 4015409
    Abstract: An attachment arm pivotally mounted on a combine to project forwardly from below the sickle cutter for limited vertical swinging movement to accommodate ground surface irregularities, wherein the arm is detachably pivoted to an individual sickle guard unit by structure spaced from and independent of the detachable connection of the guard unit to the combine, whereby the sickle guard unit serves to couple the arm to the combine in addition to its customary function, and enables the arm to be pivotally secured to and removed from the combine without disturbing the connection of the guard unit to the combine.
