Latest Patents

Walter R. Evans holds a patent for a combination lock designed to prevent manipulation for unauthorized access. This improved combination lock features a plurality of tumbler wheels mounted coaxially with a driving cam. The tumbler wheels are equipped with fence gates that must be aligned by proper combination dialing. The driving cam includes a cam gate that receives a fence nose on a fence lever when the correct combination is dialed. The fence lever is normally biased to hold the fence and the fence lever nose in an elevated position.
