Abstract

9845. Wigzell, E. E. April 22. Sounding - apparatus. - The inner transparent tube A of apparatus of the pressure type has a short length of brass tube B at its closed end engaging a bayonetjoint in the outer tube E by mean of a projection C The tube E closed by a con shaped screw plug F perforated at , J for the passage of water into the tube, which is otherwise closed by a rubber washer H, against which its open end abuts. In a modification, the tube A is closed by a perforated cap N, the water passing down a passage M and into the tube by depressing a spring-pressed non-return valve P.
