Abstract

895,164. Sounding apparatus. ROWTON, H. S. Aug. 13, 1958 [Dec. 19, 1957], No. 39575/57. Class 97(2). An apparatus for recording the depth of fishing of a trawl net comprises a Bourdon gauge 1 mounted in a watertight casing 4, the water pressure being transmitted to the gauge by a pipe 6 screwed into a hole in the casing sealed by rubber washers 8. The gauge has a main pointer 2 and a second pointer 3 for recording the maximum reading.
