  • Patent number: 11192228
    Abstract: The present invention is a floor covering fasteners and adhesives removal tool that allows for the quick removal of a staple, tack nail, and/or adhesives from a material without causing damage. The staple remover portion of the multi-purpose tool works with its forked blade for slipping underneath staples, and using the prying plate oval shape to free the staple. The tack strip nail puller portion of the multi-purpose tool having the nail slot is typically moved laterally relative to the nail. More specifically, the nail slot engages the nail where the force moving prying plate by the handle will sufficient to free the nail from the surface. The glue scraper portion of the multi-purpose tool has a bevel edge to allow the glue scraper to assume more nearly a right angular position to the floor surface sufficient to free the glue residue from the surface.

  • Patent number: 8490262
    Abstract: A hand tool which features a self-aligning recessed seating feature for easy installation of retaining clips onto the groove of the shank of mining and trenching picks. The location and orientation toward the first end of the body of the tool of the recessed seating feature allows for easy installation from either the left or right side of the holder. The tool includes two prongs located at the same end of the tool as the recessed seating feature. The end surfaces of the two prongs correspond in shape and/or orientation to the contact surfaces of a retaining clip to improve removal of retaining clips from the groove of the shank of mining and trenching picks.

  • Patent number: 8375545
    Abstract: An automotive tool serving as a pinch bar and lever for gripping an automotive suspension workpiece between first and second tool elements and an extended handle for increasing force to free the workpiece from its fastened position. Alternately, the first and second tool elements can be positioned against opposing workpieces to free one from the other again using the extended handle to amplify the applied force causing separation. The tool is designed for the automotive repair industry in the removal and installation of suspension members, such as CV joints, ball joints, struts, etc that require the dismantling of parts that have bonded due to dirt, wear and electrolytic reactions, such as oxidation, resulting in time intensive and hazardous tasks depending on the inventiveness of the mechanic in performing the separation task.

  • Patent number: 8366075
    Abstract: A pry bar sliding fulcrum assembly having a fulcrum and saddle which slidably mates with a conventional prybar and which provides a greater force onto a work material than the conventional prybar alone. The pry bar sliding fulcrum assembly easily and quickly slides away from the work material when a conventional prybar function is desired and slides toward the work material when an enhanced application force or greater prybar end displacement is required. The assembly uniquely mates with or is held with the prybar end whereby the assembly retains a static position relative to the prybar during use.
