ABSTRACT:
A liquid level sight gage has an elongated chamber block with a liquid chamber, a lens covering the liquid chamber, and a cover with an elongated viewing slot secured to the block with the lens interposed therebetween. Side beams of the cover, through which bolts securing the cover to the chamber block extend, have ovate configurations, providing greater mass at their centers, thereby providing greater support towards the centers of the chamber block sidewalls where the tendency to bulge is greatest. The bolts extend through longitudinally spaced holes in the side beams in contact with the chamber sidewalls and are transversely supported by the side beams.
