Abstract
A double acting log splitter has a longitudinally extending frame with a pair of mutually spaced fixed splitting components located along the length thereof. A movable splitting component is mounted on a carriage which is movable in opposite directions along the length of the frame between the fixed splitting components. The movable splitting component is arranged to coact with either of the stationary splitting components to split a log placed longitudinally therebetween. The carriage is driven in opposite directions by an operating mechanism which includes a nut carried by the carriage for movement therewith and a screw having one end fixed axially by and rotatably supported in bearings located at one end of the frame. The screw extends through the nut in threaded engagement therewith, with the opposite end of the screw preferably extending in an unsupported cantilever fashion beyond the nut and carriage. A reversible drive motor is connected to the supported end of the screw for rotatably driving the screw in one direction to move the carriage towards one of the fixed splitting components, and in the opposite direction to move the carriage towards the other of the fixed splittin…
