  • Patent number: 6499259
    Abstract: A one piece pad style snow guard which attaches to the vertical leg of a formed metal roof seam utilizing the formed seamed or locking portions of the seam to attach the guard without the use of penetrations or seam deformations. The guard is attached to a vertical seam by the use of threaded screws creating pressure across the slot which encloses the vertical seam. The location of the set screws intersect and lock under or into folds already in the seamed panel profile. In an alternate embodiment, a ridge located on the side of the guard opposite the locking screws and located below the lower edge of the completed folded seam runs the length of the slot. When the set screw is tightened, the entire length of the folded seam is engaged by this ridge under the folds locking the guard under the seam. This enables the guard to lock under the folded seam with out deforming the metal and lock the continuous length of the guard rather than only at the set screws, and without deforming the seam material.

  • Patent number: 4467851
    Abstract: A log splitter comprising a head portion having a cutting edge with two pivoting members each pivoting member contains cutting and thrust levers located on a single pivot point. The cutting levers are located along the head portion cutting edge. The thrust levers are displaced from the head portion cutting edge on opposite sides. When thrust against a log, the cutting levers and the head portion cutting edge simultaneously penetrate the log, followed by contact of the thrust levers causing the cutting levers to rotate outwardly in opposite directions thereby enhancing splitting of the log.
