Abstract

16,127. Armstrong, Whitworth, & Co., Sir W. G., and Noble, S. W. A. July 20. Sights, compensating, for variations in muzzlevelocity. Fig. 1 is a side elevation and Fig. 3 a sectional elevation through the axis of the range dial of a trunnion or cradle sight. The sight D<1> is mounted on an arc D working in a fixed guide C, and the range dial I is carried by a slide G working in a radial guide F attached to the arc D. The pinion I<1> of the dial I meshes with a curved rack J pivoted at one end to a pin sliding in a slot K<1> in a bracket K. By moving the slide G away from or towards the centre of curvature of the arc D, a larger or smaller range is indicated for a given movement of the sight. The invention is also applied to (1) similar sights in which the centre of curvature is below the gun ; (2) bar and drum sights, either by making the arms of the sight-bar and bracket telescopic, or, as shown in Fig. 8, by pivoting a toothed rack J in a slot N in the bracket M, and mounting the pinion of the range dial I on a pin 0 adjustable in a slot P in the sight-bar; and (3) tangent sights, by making the fore-sight adjustable in a longitudinal direction so as to increase or diminish the distance between the fore and back sights.
