Abstract
28,620. Schneider, E. Dec. 19. Sights and methods of sighting.-Consists in an apparatus for determining the total lateral correction necessary for inclined trunnions and drift. In the construction shown in transverse section in Fig. 1, and in plan in Fig. 2, the apparatus comprises a gravity member, such as a ball c, which is free to move on a concave surface a in a box e which is permanently or detachably mounted upon an arm h, on the guncradle g, or other part that moves with the gun in elevation. The surface a has lines b, b<1>, b<2> ..., the graduations at the end of which line give the deflexion correction required, when the ball comes to rest in any position, such as c', on any of the lines. A modified form of apparatus comprises a vertical plate with graduated lines thereon, which plate is applied, transversely to the gun's axis, to a part of the barrel or carriage. A cursor, pivoted to the side of the plate, carries a spirit level and is graduated with a range scale. When the trunnions are inclined, the cursor is moved until the bubble of the level (' the gravity member ') is central. The correction necessary is then given by the line on the plate which is cut by the appropriate range-graduation on the cursor.
