  • Patent number: 4336678
    Abstract: A wooden truss structure comprises upper and lower chords, each of which is grooved on the side facing the opposite chord. A web member formed of sheet material, such as plywood, interconnects the chords and fits within the chord grooves. At the web/groove interface, the webs are scalloped to provide alternating alignment guide areas and glue vent areas which extend above the interface and allow the escape of excess glue from the groove. The scalloping, in addition to venting the glue line, forms individual, pressurized glue pockets which assure even glue distribution. The scalloping is preferably provided by pressing the wood web material to compress it at the glue vent areas and thus permit the web member, due to its memory, to expand after contact with the glue. This expansion pressurizes the glue pockets and forces glue from the joint area into the wood further enhancing the expansion process. The web is rigidly bonded to the chord members, all while being aligned by the alignment guide portion.

  • Patent number: 4130916
    Abstract: A belt hook construction is provided for use with a buckle member of the class having a belt plate in which a belt hook is secured by the use of cast metal. An essential requirement is that the belt hook be held in a forwardly extended position without turning or tilting when subjected to pulling and twisting forces. Such forces develop in the wear of a belt of this class in a tightened position of adjustment. To prevent displacement by such forces, the belt hook of the invention is formed with a casting end having special anchoring means formed therein. The anchoring means are designed to project into solidified casting metal located therearound and to oppose forces acting to twist, tilt, or otherwise displace the hook from its secured position in the belt plate. The anchoring means includes ridges or rib formations arranged in angularly disposed relation to one another so as to provide greatly increased resistance to twisting and tilting forces.
