    摘要: A metal end plate for a wood product including a plurality of elongated teeth protruding substantially transversely from the intermediate portion of the plate and a plurality of elongated teeth protruding substantially transversely from at least two opposed edges of the plate. These edge teeth are located such that, when the teeth are pressed into the end of a wood product, they engage the wood fibers near the outer perimeter of the end of wood product to provide restraining force at the perimeter of the end of the wood product to prevent large splits or cracks from forming or reappearing. In a preferred embodiment, the edge teeth engage the wood fibers within about 1/2 inch of the edge of the end of the wood product. Also, in a preferred embodiment the length of the edge teeth is on the order of 17/32 inch for average density wood and longer for wood of low density.

    摘要: The anti-splitting device of the present invention has a central-web portion and a pair of end web portions, which are joined adjacent to their midpoints to opposite ends of the central web portion to provide the device with generally I-shaped cross-sectional configurations. The web portions have first side edges tapered to define a cutting edge and second side edges serving to define a planar driven surface disposed parallel to the cutting edge. And on the central web portion are at least two projections to upstand from driven surface. The projections are adapted to removably attach the device to a driver employed to insert the device into a log. The driver of the present invention is preferably in the form of a manually operational hammer having a planar driver surface of circular plan form configuration and a circular groove that has an outer diameter equidistant and an inner diameter equidistant from a given fixed point, the center of the planar driving surface. The groove receives the projections and contacts a predetermined portion of the projections; the projections exert a force on either the outer diameter or the inner diameter, and do not contact both diameters at the same time. The device can then be freely rotated in the groove to obtain a desired position on the driver surface.
