An escape chute made up of a framework which can be horizontally projected outward from a building; a double tubular body having an inner cylinder and an outer cylinder made of cloth, and a spiral slide cloth forming a slide surface which is fixed between the inner cylinder and the outer cylinder; an upper entrance at the top and an exit at the bottom; one or more intermediate access apertures and intermediate entrance passages made of cloth to permit entrance into the space between the inner cylinder and the outer cylinder wherein the height of the lower edge of the intermediate access aperture is higher than the spiral slide surface at the position so as to prevent a part of a person from becoming hung up upon the aperture. The intermediate entrance passages are held by ropes connected to the framework. One or more intermediate exits are formed on the side surface of the bottom outer cylinder at higher than the exit.

An apparatus for deploying and taking up an oil fence comprises a floating framework having a substantially enclosed oil fence receiving space therein and 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.

Apparatus for deploying and taking up an oil fence

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.
