DonaldAttorney, Agent or FirmInternational ClassB27L 7/00 (20060101)AbstractA portable wood splitter is disclosed having a splitter frame adjustably mounted to a support frame. In one embodiment the support frame is wheel supported and in another embodiment the support frame is mountable to a vehicle such as a tractor for transport. The splitter includes a splitter beam with a blade mounting slide plate powered to move toward and away from a platform at a lower beam end. The slide plate includes safety features to avoid finger injury. A double gib adjustment on the slide plate facilitates adjustment for wear and enables centering adjustments of the blade on the beam. The beam is mounted to the support frame by a clamp arrangement that will facilitate selective longitudinal adjustment of the beam relative to the frame. The beam is pivotal, on the first embodiment between a horizontal position overlying a towing tongue and an upright position. An adjustment feature enables re-positioning of the towing tongue from its horizontal operative position to an upright compact condition where an end of the tongue engages the ground surface to stabilize the unit.Other References
