Frederick Walz from Burnside Connecticut was issued patent 1,792,338 on February 10, 1931 for a quick adjust wrench that kind of resembles a Crescent style wrench and functions similar to the Palmeter wrench. A lever operates the linkage that releases the spring loaded dynamic jaw. A extension spring goes through the dynamic jaw, one end is anchored to the dynamic jaw and one end is anchored to the main frame. The wrench sections are riveted together.
