ABSTRACT:
The face and head protective hood assembly has a window plate for vision, a movable flexible transparent film over the window plate, payout means for the film, and take-up means for removing soiled film. The payout means consists essentially of an elongated housing with a narrow slot in it faced toward the hood assembly. A free-standing non-rotatable shaft is fixed centrally in the housing. A hollow payout roll of flexible transparent film is mounted for rotation about the non-rotatable shaft. Resilient means on the exterior of the non-rotatable shaft presses against the hollow interior of the payout roll to frictionally resist rotational movement of it. The take-up means consists essentially of a take-up shaft free of an external housing, a hand operated knurled wheel fixed on it, bracket means on the exterior of the hood assembly for removably mounting the ends of the take-up shaft for rotational movement by turning the knurled wheel, and a leaf spring in biased relationship against the knurled wheel to limit rotational movement of the take-up shaft to one direction only.
