US 4,302,851 A · High temperature protective mitt

Abstract

This mitt, which is completely free of asbestos fibers, comprises hand and thumb sections, each of which is made from a wood knit liner enclosed in a layer of woven material made from temperature-resistant aromatic polymide fibers which are sold under the trademark "Kevlar". Layers of aluminum foil and flexible fiberglass are incorporated between the inner and outer layers of the hand section to increase its protective properties. Secured to the outer surface of each section is a pleated pad of flexible material woven from fiberglass yarns. Alternate pleats in each pad overlie intervening pleats, thereby forming spaced, parallel, raised surfaces which come into direct contact with the hot product handled by the person wearing the mitt. Flexible inserts in the form of fiberglass enclosed in aluminum foil may be inserted beneath the outer pleats for added protection; and additional layers of aluminum foil and fiberglass can be positioned between the pads and the outer surfaces of the respective thumb and hand sections to which they are secured.
