Abstract:
1. A trailer-mounted table wood splitting apparatus comprising: a trailer assembly comprising a frame for structural support, a floor affixed to said frame for supporting operational assemblies, a tow assembly affixed to a distal end of said frame for removable connection to a tow vehicle, and a pair of wheel assemblies attached to opposing sides of said frame; a splitter wedge rigidly affixed on said floor disposed toward a front end having a pair of sloped surfaces facing a rear end of said trailer assembly for splitting wood forced against said splitter wedge; a hydraulic assembly comprising a hydraulic cylinder mounted to said floor and aligned with said splitter wedge for forcing wood against said splitter wedge, a hydraulic pump for driving said hydraulic cylinder, a hydraulic control valve in fluid communication between said hydraulic pump and said hydraulic cylinder for controlling actuation of said hydraulic cylinder, and a hydraulic fluid storage tank in fluid communication with said hydraulic pump; a boom assembly comprising a supporting structure affixed to said trailer assembly rear end, a boom pivotably mounted atop said supporting structure and extending laterally therefrom, a pair of pulley assemblies disposed on opposing ends of said boom, and a lifting cable routed through said pair of pulley assemblies and terminating at a log tong for lifting and placement of wood; a winch assembly comprising a winch spool affixed to an end of said lifting cable opposite said log tong for winding up and winding out said lifting cable, a winch shaft affixed through said winch spool and rotatably mounted to said supporting structure, and a winch pulley rigidly affixed to an end of said winch shaft for cranking said winch spool; a drive assembly comprising an engine having a rotating drive shaft and an engine pulley affixed to said drive shaft, a transmission for providing speed and torque conversion of said drive shaft having an input pulley in mechanical communication with said engine pulley by an engine pulley belt and an output pulley in mechanical communication with a drive pulley by a transmission belt, and a friction pulley rigidly connected to said drive pulley and in mechanical communication with said winch pulley by a winch belt; a winch drive control mechanism comprising an engaging roller selectively engaged into pressure contact with a slack side of said winch belt from an outside position, an elongated off-set roller arm affixed to said engaging roller and rotatably connected to said supporting structure, at least one engaging lever for selectively engaging said engaging roller into pressure contact with said slack side of said winch belt, and at least one engaging link member pivotably attached to and for mechanical communication between said roller arm and said at least one engaging lever; and, a braking mechanism comprising a brake pad selectively engaged into pressure contact with said winch pulley, a bracket connected to said brake pad, at least one brake lever for selectively engaging said brake pad into pressure contact with said winch pulley, and at least one brake link member pivotably attached to and for mechanical communication between said pivot bracket and said at least one brake lever.
