ABSTRACT:
A rail bridge rescue frame comprises three elongated legs having upper and lower ends. The upper ends are secured to a head assembly so as to universally pivot with respect thereto. Two of the legs are forward legs of shorter and similar length and the third is a rear leg of longer length. Means are secured to the lower end of each of the forward legs to bear against a side portion of a rail. Means are attached to the lower end of the rear leg to secure to a portion of a rail. The frame is constructed so that when the rear leg is secured to one rail of a railway and the lower ends of the forward legs are bearing against outer portions of an adjacent rail thereof, the head assembly will be positioned clear of the railway to one side to provide support for a line to lift a person or the like below the railway up to the level of the railway.
