  • Patent number: 7255143
    Abstract: A uniquely configured quad wedge allows for the creation of a tip-up log splitter that is capable of multiple splits in a single stroke of the drive mechanism. The quad wedge is attached to the piston of a hydraulic cylinder, and is slidably mounted to a framework to allow for movement through a splitting zone. The quad wedge further includes a main splitting blade, along with a pair of splitting wings extending outwardly in a perpendicular manner. The blades each have structures on the ends thereof which are configured to help contain a log during splitting operations, thus avoiding undesired movement or wandering. The log splitter further includes a stripper mechanism positioned near the cylinder housing to allow jammed logs to be easily removed, which includes a recess to house the quad wedge when retracted. A jammed log will necessarily contact the stripper mechanism, causing it to be removed from the blade.
