Abstract
Abstract A vehicle is movable along the upright outer surface of a ship''s wall in a horizontal path. A mast on the vehicle extends upwardly along the surface and has an upper end portion, the mast being extensible and retractable. An evacuable container is provided on the upper end portion of the mast displaceable at least with reference to and along the surface and having an open side facing and adapted for fluid-tight contact with a registering portion of the surface. Nozzle means is arranged within the container and operative for dispensing a treating medium through the open side onto the registering portion of the surface.

Claim 1
Independent Claim
214 words
An arrangement for treating substantially upright surfaces, particularly outer surfaces of ship''s hulls, comprising a vehicle movable along and spaced from a surface to be untreated; a mast on said vehicle extending upwardly along said surface and having an upper end portion, said mast being extensible and retractable; evacuable container means provided on said upper end portion displaceable at least with reference to and along said surface, and having an open side facing a portion of said surface, said container means including sealing means for sealing the juncture of said open side and said surface, including sealing rollers provided at edge portions of said open side which respectively lead and trail relative to the direction of displacement of said container means and extending substantially across the entire width of said edge portions, and belts of sealing material at the remaining edge portions of said open side for sealing the latter; nozzle means arranged on said container means and operative for dispensing a treating medium onto said surface; and evacuating means communicating with the interior of said container means to substantially evacuate the same when said open side abuts against said surface, whereby the pressure difference between the interior and the exterior of said container means causes the same to be forced against said surface.
