Abstract

11,193. Mertz, V. E. May 12. Check valves. - A hinged check valve b is made a loose fit on its pivot c, and is loaded by by one or more helical springs e, of which the free ends bear on the valve, and the other ends are secured to the pivot to enable the tension of the springs to be adjusted by rotating the pivot and securing it by a set-screw. When two springs are used, their free ends are joined by a bar f.
