  • Safety air guns
    Patent number: 7591435
    Abstract: A safety air gun may include a body, a valve, and a valve-operating lever. The body may have a shape that curves from an inlet end to an outlet end, thereby defining a convex side and a concave side. The body may define a bore that extends between the inlet end and the outlet end. The valve may so intersect the bore as to regulate flow through the bore. The valve-operating lever may be positioned on the convex side of the body and operably coupled to the valve.
