ABSTRACT:
An apparatus for splitting logs and the like is disclosed. The apparatus comprises an elongated track having an upstanding splitting wedge attached thereto and a ram slidingly mounted thereon. The ram includes an upstanding abutment plate and an upstanding drive plate which is spaced from the abutment plate on the opposite side thereof from the wedge. A cable-wound-drum electrical power unit which is operable with advance, hold and release modes is mounted at an intermediate point on the track between the drive and abutment plates with the cable of the power unit extending from the drum to the drive plate. Upon implementation of the advance mode of the power unit, the cable is wound onto the drum to pull the drive plate towards the power unit and thereby advance the abutment plate towards the wedge. The splitting of a log or the like interposed between the abutment plate and the wedge on the track is effected by advancing the abutment plate together with the log toward the wedge thereby causing the progressive longitudinal insertion of the wedge into the log. The ram is thereafter rapidly returned from the wedge by resilient spring members upon implementation of the release mode of the power unit.
