Abstract
An array of semicylindrical floats juxtaposed on one surface of a longitudinally elongated screen about each of spaced cross strips on the screen opposes a similar array disposed on the other surface of the screen and a chain-shaped sinker is disposed along one longitudinal edge of the screen. Also a floating framework is disclosed having one side partly cut away and roll means disposed in front of the cut-away portion. The roll means can be driven to sinuously house the oil fence within the framework and to pay it out from the latter. Alternatively, a takeup shaft disposed in a box-shaped member with buoyant chambers and fenders may be driven to coil and uncoil the oil fence on and from it through one open side of the box-shaped member.
