DEFINITION

Classification: 405/11

MEANS TO EXPOSE A NORMALLY WETTED SURFACE, E. G., COFFERDAM, ETC.:

(under the class definition) Method or apparatus wherein means are provided to form a temporary removable enclosure about a portion of a submerged surface so that the water contained within the enclosure means can be evacuated to thereby expose the surface portion to the air.

(1) Note. The type of structures to be found herein are removed once work on the submerged surface is completed. Thus, those caissons or cofferdams which physically become part of and are inseparable from a structure formed within such caissons or cofferdams will not be found in this or the indented subclasses.

(2) Note. While the enclosing means found herein are usually used to expose a portion of a sea, lake, or river bed, those devices which are used to expose portion of a ship's hull or sea wall, so that work can be performed thereon will also be found herein.
