Latest Patents

Croghan holds a patent for the "Zero Lead Planer." This invention improves the traditional planer by addressing the instability of a board relative to a guidebar. The design features an angled relationship between the feed roller and the guidebar, which holds the board securely in place. Traditional cutting heads often create lateral forces that can push the board away from the guidebar. By establishing a zero lead relationship between the cutter heads and the board, Croghan's invention enhances stability during operation. Additionally, the apparatus includes an air-regulated top pressure plate that maintains a specific separation from the cutter head, accommodating abnormal conditions such as jammed boards. This feature allows for quick relief of jams through vertical movement, improving overall efficiency.
