  • Patent number: 7913726
    Abstract: A trailer-mounted wood splitter with an integral platform, log boom and grappler provides an extended table area to facilitate the splitting of wood. The apparatus comprises a hydraulic-powered wood splitting assembly operated by an internal combustion engine mounted to a trailer. A horizontal surface worktable is provided all around the upper surface of the wood splitting plane. In such a manner, any wood that is placed upon the platform for splitting does not fall off after splitting is complete. This allows the user to reposition any remaining sections of wood for additional splitting without having to pick them up off the ground. Once completely split, the wood can be directed to the side of the table or platform for stacking or transportation. The apparatus further comprises a log boom with a grappler attached to a far end for moving and manipulating felled logs.

    Abstract: A hands-free wood (log segment) splitting apparatus and method of employing a mobile vehicle having mounted thereon the splitting apparatus. The splitting apparatus includes a mount removably secured to the mobile vehicle and having secured thereon a rotatable auger, the location of the mount and the components carried thereon being safely remote from an operator. Control over the positioning of the apparatus, including the auger relative to a to-be-split log segment, control over the movement of the auger relative to the log segment being split, restraining the log segment from undesired movement relative to the spinning auger, and other related actions, are effected by the operator from the remote location and without exposure of the operator to personal injury from the splitting apparatus. Guides are provided for entry thereof into a split to serve as impediments to collapse of the split portions of the log segment against the auger.

  • Patent number: 4646800
    Abstract: A log splitting apparatus and method for use in conjunction with a substantially horizontally mounted source of rotational power, such as the take off (20) and hitch lift unit (16) of a farm type tractor (10). The apparatus is disclosed in the form of a rigid frame (30) attached to the unit (16), and includes strut members (26,28) for maintaining the frame in a horizontal orientation. A drive shaft (60) is horizontally supported through the frame with one end connected as a universal joint (40) to the take off, and the other end extending behind the frame. A drive transfer gear arrangement (42) is connected to the extending end of the drive shaft, and an auger (44,46) is perpendicularly connected to the transfer gear arrangement. Preferably, the tractor is maneuvered to straddle a series of end-to-end logs (12) so that the auger (46), while pointing downward and rotated by the power take off and drive shaft, is lowered onto and lifted from each log in succession, by means of the lift unit.

  • Patent number: 4553576
    Abstract: A log splitter has a rotatable cone driven by a reversible motor. A system of lever arms support a log in a V-shaped carrier positioned under the point of the cone. When the lever arm is operated, the log is pushed against the point of the rotating cone, which splits the log. If the log fails to split, the motor is driven in the reverse direction, which releases the log.

  • Patent number: 4491164
    Abstract: This invention comprises a portable impact driven log cone splitter mounted to a power source such as a chain saw power unit. The wood or log splitter is coupled to a chain saw power unit through an appropriate gearing arrangement in one preferred embodiment. The blade is removed from the conventional power saw unit and the wood splitter is readily mounted thereto in an orientation having a hollow splitting screw cone with a starter tip parallel to the longitudinal axis of the unit. The cone is mounted over an impact drive unit which is coupled to the gearing arrangement to provide a safe reliable drive. This arrangement also permits a portable log splitting unit which is relatively inexpensive and simple to use and with the cone removed permits use as an impact tool.

  • Patent number: 4460027
    Abstract: This invention is a log splitting device which is easily maneuvered over the log to be split whereupon the spiral, conical shaped splitting member bores into such log to split the same. Reverse or back-out mechanisms are also provided should an extremely knurled or knotted piece of wood be encountered. To accomplish these ends, a frame for a motor and the splitting member is mounted on oversized tires and is counterbalanced to allow even a small woman or child to manuever the same into log splitting position. The logs are split while lying horizontally on the ground thereby eliminating the necessity of having to pick the same up prior to splitting as is common among the prior art splitting systems.

  • Patent number: 4425950
    Abstract: A log splitting apparatus is provided having a rotatably driven splitter cone extending forwardly from a housing. A horizontal stabilizer base assembly extends forwardly from the bottom of the housing. The apparatus, optionally, rests directly on the ground or indirectly on the ground through elevating blocks. The stabilizer base assembly includes a base plate at one side of the housing and a transverse torque arm extending to the other side of the housing. The base plate has a pivoted connection to the one side of the housing about an axis extending substantially parallel to that of the splitter cone and is positioned to engage a log being pierced by the splitter cone to thereby enable the base plate to absorb torque reaction at the one side of the housing. The free end of the torque arm engages a support member extending forwardly from the opposite side of the housing to absorb additional torque reaction at that opposite side, thereby tending to neutralize any twisting or lifting forces applied thereto.

  • Patent number: 4347881
    Abstract: A rotatable threaded cone is secured at the front of a support mounting having a bevelled end which facilitates the passage of a block of wood split by the cone such that large blocks may be split in one operation without the need to withdraw the block to reintroduce the cone into the block at a different place. A platform is pivoted by means of pivot bolt at the end of a support arm to which it is also connected by means of a ratchet assembly and bolts whereby undue pressure on the platform during a block splitting operation will result in the downward pivoting of the platform to thus relieve the pressure on the cone and the drive thereto.
