Abstract

207,539. St³tzer, R. Nov. 27, 1922, [Convention date]. Sights and methods of sighting.-For direction finding and indirect aiming, a sighting-device a is trained upon a stationary condensing-lens system d having a measuring-screen e with a wide field graduated in angles to correspond with a scale b movable with the gun or other object to be directed. If the gun is disturbed by the recoil, the difference between the old and new readings on the scale e is noted, and this gives the angle through which the gun and scale b must be turned to restore the correct aim. The scales may be modified to permit of correcting the vertical aim. The open-sight a may be replaced by a telescopic sight the eye-piece of which is furnished with a scale corresponding to the scale b.
