Abstract

125,685. Rosenbaum, B. Feb. 4, 1918. Drawings to Specification. Methods of sighting.-For alining a gun each time after it has been fired, a plane mirror or paralleloscope is fixed near the gun and a telescope on the gun alined and focused on the image of the sight seen in the mirror. After firing, the gun is moved until the image of the sight in the mirror is again visible through the telescope.
