| Abstract: |
An improved welder's shield for electric arc welding comprising a flexible gasket secured to and protruding from the inside surface of the face mask. The gasket circumscribes the viewing window of the mask and flushly meets the face of the wearer about his eyes to provide a curtain thereabout and to prevent indirect radiation from being passed thereto by reflection or otherwise. The shield is preferably provided with a pivot point, when the face mask is secured to the head harness, located so that the mask, when being moved from or to face shielding position, is not obstructed in its movement by interference of the facial features of the wearer by the gasket.

I claim as my invention:
1. A welder's shield for use with an electric arc welding system, the shield comprising a face mask having front and side wall portions for extending in front and to the sides of the face of a wearer, and viewing means in the mask to protect the eyes of the wearer against direct radiation from the arc but to permit him to see his work, the improvement comprising a flexible gasket protruding from the inside surface of the face mask, the base of which gasket includes separable fastening means cooperating with mating fastening means on the inside surface wherein said gasket is removably secured to that inside surface, the gasket circumscribing the viewing means, to flushly meet the face of the wearer and encircle his eyes to prevent indirect radiation from being reflected thereto, the shield further comprising a head harness and the mask being directly secured to the head harness by a pivot located on a vertical extension that projects above the head encircling portion of the harness for unobstructed movement of the shield from a position above the face of the wearer to a face shielding position or vice versa, manually operable means for adjustably securing the face mask in these positions or positions therebetween.
