Abstract
Abstract For use to protectively cover the valve outlet on the top of a pressurized cylinder, such as is often used by scuba divers, which has a generally hemispherical top and a valve extending upwardly from it. The device is a hood sized to receive the upper end of the tank and the valve to protectively house the latter. The hood has means to connect to the tank at the lower end and to the valve, there being a hooked member for hooked-up engagement with the valve with a portion extending through the top of the hood and a lock nut to hold the same in place.
