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.

A log splitting wedge secured to one end of the frame and a hydraulic cylinder and ram / piston secured to the other end of the frame. The ram / piston being movable toward and away from the wedge. The reservoir includes an inlet and outlet and a discharge tube associated with the inlet having a length effective to discharge incoming fluid into the reservoir at a position remote from the inlet. The elongated tube may be associated with the reservoir outlet so as to draw fluid from the reservoir and thus maximize flow from the reservoir even if the reservoir, or log splitter is in a tipped position. A log splitter and arm for mounting the splitter to a vehicle having a hitch style receiver secured to the rear of the vehicle. The splitter has a substantially linear working action. The mounting system includes an elongated arm for securement to the receiver in a cantilever fashion. The splitter is adapted to be secured, by a pin or a set screw mechanism, to the arm and be supported above the ground. The splitter's linear working action is substantially normal to the vehicle's direction of movement and the support arm. This system permits the vehicle to travel at normal highway speeds and carry the splitter.

A log splitter comprises a support structure having a first end, a second end, and an open center portion defined therebetweeen, a splitting device slidably coupled to the support structure, and a drive mechanism for driving movement of the splitting device through a splitting zone.

A new or retrofit block hoist for conventional, hydraulic-powered log splitters assists in the lifting, maneuvering, and positioning of large diameter, heavy logs that require multiple radial splits to section them for firewood, comprising a boom, pulley and cable system. A boom assembly is secured to the top end of the splitter guide beam and pulleys guide a lifting cable anchored to the wedge slide to a log section retainer means (dog or awl). The upward, hydraulically-powered movement of the cutting wedge along the I-beam lifts the log section as the wedge is raised into its upward, retracted position. Once lifted, the log is swung into position between the wedge and splitter foot plate. The wedge is then power extended (lowered), splitting the log. An optional turntable is securable to the footplate. The inventive block hoist can be provided as a kit.

This log splitter is designed to work very fast and efficiently, yet be less expensive to construct than comparable splitters. By using a single, vertical, rectangular post to support all the split wedges including the two-way, these wedges can be of a simpler, less expensive, yet as strong construction. Secondly, by angling the Split Wedge Post slightly forward, it retains the split wedges during splitting operations, limits them to rise only slightly as the wood passes through, yet allows them to be freely and easily placed and removed by hand by the operator. The manually operated Height Adjuster Bar located conveniently on the side of the beam, allows the operator to easily and quickly raise and lower the split wedges as necessary to accommodate different sized logs and to retain the wedges in place with a simple latch type arrangement.

This invention adds a very large (24×32 inch or larger) log table permanently mounted to the log splitter. This alone adds immeasurably to the efficiency and convenience of splitting. It allows for the true, convenient, and safe one-man operation of a splitter because it catches and stores the far side of the log and log pieces while the operator is free to handle the near side with one hand and the control valve with the other hand. The log lifter is powered hydraulically with the same cylinder, control valve, hoses and fittings that power the split wedge. Very simply, a cable and a pulley are used to direct the force of the existing cylinder to raise the log lifter. This simplicity lowers the cost of the log lifter considerably and makes it and the log table and the convenience of splitting in a more comfortable, standing position more readily available to the splitting public.

A manually-operable log splitter for use with a splitting wedge has a pair of jaws pivotable about a point. Each jaw is connected to a handle extending away from its associated jaw from the pivot point. The jaws have a tip smaller than a width of the splitting wedge with which the splitter is used. The jaws and handles are dimensioned and configured for insertion beside the splitting wedge when embedded in a log. Manual application of force F on each handle outward from the pivot point spreads the jaws and provides sufficient force for splitting the log. This tool is particularly suited for small scale log splitting, such as by a home owner for personal use.
