Abstract
Abstract The present disclosure is directed to a rigging system for causing an endless oil mop driven through an engine or motor driven wringer mechanism to make multiple passes over and through an oil contaminated body of water from the deck of a vessel. This is accomplished by using sampson posts on the deck of a vessel and connecting spars to the posts and buoyantly supporting the free ends of the spars and mounting mop pulleys at the end of each spar and one pulley between the spars on the side of the vessel at the water line.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
241 words
In combination with a vessel and an endless oil mop means for collecting a light liquid from the surface of a body of water by the adherence of said light liquid to said oil mop means, a rigging system for said endless oil mop means comprising a pair of spars with a first end of each spar pivotably connected to sampson posts spaced apart at one edge of the deck of said vessel, wringer means for cleaning liquid from said oil mop means, said wringer means located at the edge of said deck between said sampson posts, a first pulley for said endless oil mop means located adjacent said wringer means at the side of the vessel where the spars are located, float means for supporting the second end of each spar when the spars are arranged horizontally with the second end of each spar adjacent the surface of the water, pulley means comprising second and third pulleys located at the second end of each spar, continuous endless oil mop means constructed and arranged to have a first portion located away from the vessel and a second portion located between said first portion and the vessel, said first portion being supported by being roved through said first, second, and third pulleys, said second portion being supported by being roved through said second, third pulleys with the central portion thereof roved through said wringer means mounted on the deck of the vessel.
