<p>"LOG SPLITTER" An electrically driven log splitter comprises a frame with a double wedge assembly on one end and a ram carriage slidable along the frame towards and away from the wedge assembly so that a log on the frame will be engaged against the wedge assembly and be split thereby when the ram carriage engages the other end of the log. An electric motor drives an endless chain at a constant speed with the chain extending around sprockets mounted on the frame and being driven by the electric motor through reduction components. The ram carriage mounts a pair of sprockets with the chain passing over one sprocket and under the other. This permits the carriage to be moved manually along the frame with the chain idling over these two sprockets, A log is mounted on the frame against the wedge assembly and the carriage is moved manually along the frame to engage the rear end of the log with the chain idling around the two sprockets within the carriage. An operating handle with a pin extending therefrom is pivotally mounted on the carriage and is moved to engage the pin with the teeth of one of the sprockets thus locking the carriage to the chain which moves the carriage against the log and forces it into the wedge assembly thus splitting the log. A rod extends rearwardly of the lever and passes through an apertured disengaging plate. The rod has an adjustable stop on the distal end thereof which strikes the plate when the carriage is at the end of its travel thus disengaging the pin from the sprocket at this point.</p> |
