| 2000 | Invention patented by Milford R. Murphy on February 3rd, 2000. Abstract: The invention is a man-portable firewood splitter and is affordable for personal use. It uses an off-the-shelf hydraulic car jack, an off-the-shelf firewood splitting wedge, and a platform that is configured so that it combines the other two units to provide a firewood splitting function. The components are physically unattached and can be used for other requirements. The platform is somewhat like to a bed with side rails. It consists of two end plates, a bottom, and two side rails. It is structured to withstand the maximum force of the hydraulic jack. To assemble the system, the jack is horizontally placed on the bottom of the platform with the jack base butted against one of the end plates and oriented so that the jack handle is vertical. The blunt end of the splitting wedge is horizontally placed against the ram of the jack. The firewood to be split is horizontally placed on the bottom of the platform with one end against the other platform end plate, and, hence, the other end will be exposed to the blade end of the wedge. Blocks of wood are placed under the jack and the Wedge to elevate them to the desired height For splitting firewood. The stick of firewood is split by moving the jack handle for and aft which drives the wedge into the wood. The jack has a nominal stroke of 5 inches. If a longer stroke is needed, the ram can be reset and the jackscrew extended. |
