Abstract

576,770. Gas meters. ROBINSON, V. June 29, 1944, No. 12390. [Class 54] The valve covers are enlarged between the lands seating on to the valve grid to secure unimpeded flow. The cover a is hollowed out at band c between the lands d, and the cover lands d are broad relative to the seating lands e. The end walls of the valve covers may be similarly hollowed out and the valve grid ports f open out widely as shown.
