IMPROVEMENTS IN FIREPLACE WOOD CUTTING MACHINE Abstract of the Disclosure In a first embodiment of the invention an elon- gated support frame is provided including inlet and outlet ends. The inlet end includes an inclined loading conveyor and a winch is supported by an upper portion of the frame and has a drag cable connected thereto for length- wise winching logs toward the loading conveyor. Shear structure is supported from the frame adjacent the upper end of the loading conveyor whereby end portions of logs being advanced along the conveyor may be cut therefrom and an elongated trough is provided for receiving cut log end portions. One end of the trough includes stationary wedge structure and a power ram is provided for forcing cut log portions along the trough into engagement with the wedge structure, whereby the cut log portions may be split into multiple log sections. An inclined discharge conveyor is positioned to receive the multiple log sections from the wedge structure and is operative to elevate the logs to an elevated discharge end of the discharge conveyor for gravity discharge therefrom into a suitable receptacle. In a sec- ond embodiment of the invention, the wedge structure is displaced laterally of the shear structure and a ramp is provided downstream of the shear structure for displacing the sheared log portion and positioning it for splitting. In this embodiment the wedge structure translates, rather than being fixed, between a retracted position which is upstream of the shear structure and a cutting position which is downstream of the shear structure. When the log portion is positioned for splitting after it has been sheared it is restrained by a backing plate and the wedge structure is forced through it rather than it being forced through a stationary wedge. Therefore, the machine can be made shorter and more compact than in the first embodiment.
