  • Patent number: 5115580
    Abstract: Apparatus for drying a hand covering with a wrist portion includes a closure which makes a snug fit within the wrist portion. An inlet aperture is connected to a source of drying gas, which inflates the hand covering. One or more outlet ports through the closure permits vapor-laden gas to leave the interior of the hand covering. Restrictive means limit the flow of gas from the hand covering to ensure full inflation. In terms of method, a wet hand covering, which includes a finger section and an elastomeric wrist portion, is dried by inserting a closure in the wrist portion. A drying gas is injected through an inlet aperture in the closure and into the hand covering at a sufficient rate and temperature to inflate the finger section and vaporize liquid. Vapor-laden gas is removed from the hand covering through an outlet aperture in the closure.
