Abstract

17,929. Moir, T. Dec. 23. Sounding-apparatus.-A sea-sounding apparatus comprises a weighted or spring-loaded arm 7 pivoted to the frame and carrying a fair-lead 11 for the sounding-li@e, so arranged that the weight of the lead holds a worm-wheel 15 or its equivalent carried by the arm 7 in engagement with a worm or its equivalent on the spindle of the drum 1, but when the lead touches bottom, the spring or weight 10 disengages the worm and worm gear. The wormwheel has a graduated face by which the depth is recorded, and is preferably provided with graduations corresponding to different inclinations of the lead line. In order to prevent the drum from rotating after the lead has touched bottom, a hand brake comprising bands 19 operated by levers 20 is provided. When used for deep-sea sounding, a retarding-device comprising a spring-pressed pin 22 may be provided.
