ABSTRACT:
A log splitter device is disclosed using a slide hammer type configuration for the driving of a wedge. The wedge itself defines an abutment surface which includes a shaft member extending outward therefrom. An annular member of generally tubular configuration is configured with the central bore into which extends the shaft member. A weight means is fixedly secured with respect to the annular member to provide added momentum. Two impacting areas are defined by this device such that each impact occurs simultaneously to increase the efficiency of momentum transfer from the weighted annular member to the wedge. An upper impact is achieved by a core member which is fixedly secured within the annular member contacting the upper edge of the shaft member extending through the central bore thereof. A second impact is created by the lower end of the tubular member in direct contact with the abutment surface of the wedge. An adjustment feature may also be included as a wedge spacer to adjust the distances to assure simultaneous impact of the first and second impacting areas.
