ABSTRACT:
A power operated log splitter adapted for the relative movement of a wedge means (14) and backing plate means (16) between spaced apart first and second positions (A and B) by the linear movement of an operating arm (12) of a hydraulic cylinder (11) mounting the wedge means (14) on the backing plate means (16) from an idle position (A) towards and away from the fixed backing plate means (16) or wedge means (14) to split the logs (100) is described. The log splitter includes a moveable pressure plate (18), preferably mounted on the backing plate (16), and a mechanical linkage means (19) connected to the moveable pressure plate (18) which actuates a valved control means (17) for the hydraulic cylinder (11) when the pressure plate (18) is in contact with a log (100) to initiate movement of the operating arm (12). Upon splitting of the log (100) and removal from the spaced apart positions (A and B) the pressure plate (18) disengages the linkage means (19) from the control valve (17) to return the operating arm (12) to the idle position (A). The wedge means (14) is provided with a projection which interferes with an adjustable block on the linkage means (19) adjacent the idle position (A) to stop the arm (12). The log splitter is particularly adapted for use by a single operator.
