Abstract
An improved welding hood with a chin operated face shield provides hood stability, adjustability, ease of use, long life, an ability to hook the viewing window shield open, and positive closing of the shield otherwise. A linkage from the chin of the operator pivots the viewing window shield on the face shield. A spring biases the shield closed, is adapted to be hooked, and is attached to the shield and the linkage.
