  • Patent number: 4193132
    Abstract: A rain-shielded welder's mask assembly comprises in combination a head piece, a welder's mask with eye piece, and pivotal mounting means attaching the mask to the head piece.A rain shield is mounted pivotally above the eye piece and connected to the head piece for raising and lowering upon relative angular movement of the mask with respect to the head piece. In its raised position it extends horizontally above the eye piece protecting the same from rain in the operative position of the mask. In its lowered position it nests over the eye piece, protecting it from rain in the raised inoperative position of the mask. A gutter is mounted on the front of the mask above the eye piece for diverting rain water therefrom. The welder thus is enabled to work steadily in rain conditions without stopping frequently to clean the eye piece of his mask.
