Abstract: A harvester row unit includes first and second deck plates having first and second stripping edges which are facing and spaced apart for defining a stalk gap therebetween, first and second gathering chains extending over the deck plates and comprising a plurality of sweeping lugs which traverse adjacent to and along the stalk gap, and one or more kernel brushes secured to the sweeping lugs by fasteners. The kernel brushes can include brush bodies, sweeping portions secured to the brush bodies, and mounting blocks. The sweeping lugs can include lug walls wherein the brush bodies and mounting blocks sandwich the lug walls. Preferably, the kernel brushes are secured to the sweeping lugs by nuts and bolts, and the brush bodies and/or mounting blocks include fastener bores adapted to receive the bolts and fastener slots adapted receive and align the nuts with the fastener bores.

Abstract: A harvester row unit comprises first and second deck plates having first and second stripping edges which are facing and spaced apart for defining a stalk gap therebetween, first and second gathering chains extending over the first and second deck plates and comprising a plurality of sweeping lugs which traverse adjacent to and along the stalk gap, and one or more elastically compressible stalk gap rails mounted to the first and second deck plates adjacent to and extending along the first and second stripping edges. The stalk gap rails include a ramped leading end and a trailing end, and the sweeping lugs climb up the ramped leading end, traverse across the stalk gap rails, and climb down the trailing end, and/or include support pads and pockets between adjacent support pads defining one or more flexible walls which deform when impacted by kernel carriers.

Abstract: A waler clamp having a structure that facilitates placement of a waler board between upper and lower plates of the waler clamp, and, at the same time, provides excellent rigidity and strength against deformation and twisting of the waler clamp as a wedge is driven through openings in the waler clamp to wedge a board against abutting vertical frame members of adjacent concrete wall forms is provided. The clamp includes an upper plate having a hook for engaging the wall form, a lower plate spaced below the upper plate, the upper and lower plates interconnected at respective longitudinal edges by a side web having an opening adapted to receive a waler board.

Abstract: A concrete wall form having spaced-apart wall forms forming opposing surfaces that define a cavity for forming a concrete wall are provided with a plurality of improved lighter weight wall form ties that hold the walls in a desired relationship. The improved wall form tie includes an elongate strip of material having two opposite elongate edges and a fastening aperture defined at each of two opposite ends of the elongate strip for attachment of the wall tie to wall forms. A plurality of notches spaced-apart along each of the two opposite elongate edges of the strip between the fastening apertures facilitate proper placement and retention of reinforcing bars in a cavity defined between the concrete wall forms. Weight-reducing apertures defined within an area between adjacent notches provide recyclable scrap material and reduce the weight of the wall form tie, thereby reducing manufacturing and freight costs.
