Incredibly strange, but oddly sensible, Cold War shelter invention: Patent images for Harold C. Tifft’s ‘Portable Shield’ originally filed on 17 April 1956.
The bottom image shows two possible positions for the wearer: face first flush against the wall, or face first flush against the ground (or floor).
The main object of this invention is to provide a portable shield which will serve to guard the human body from the injurious or lethal effects of a nuclear explosion.
A second object of this invention is to provide a portable shield against nuclear explosions which can be easily and quickly placed around a considerable portion of the human body.
Another object of this invention is to provide a shield which can be adjusted so that it will substantially cover the entire body of the wearer, regardless of whether the wearer is in a standing, sitting or reclining position.
A further object of this invention is to provide a shield for the body which, in addition to being portable, also can be readily adjusted by the wearer so as to permit him to run from one place to another and yet still have a substantial measure of protection on the upper portion of his body.
