Abstract
Abstract A log splitter comprising a wedge supported on an upright in overlying position with respect to a log to be split and guided on the upright toward the log when the wedge is struck by a hammer. An auxiliary driver is supported on the upright for movement into and out of alignment with the wedge and for movement with the wedge such that when a log is initially split by the wedge and becomes jammed in the log or is driven into the log so that the hammer cannot reach it, the auxiliary driver may be brought into alignment with the wedge and the hammer will then strike the auxiliary driver and drive the wedge through the log.
