Abstract

13,335. Dawson, A. T., and Buckham, G. T. June 23. Sights and methods of sighting.-A device for levelling the sights when the trunnion axis is inclined is shown in side elevation in Fig. 2. Fig. 4 shows a section on the line 1-1 of Fig. 2. The sight bar D<1> is supported by a sight-carrier D which has a strap portion d surrounding a disk C pivotally mounted at c on the cradle trunnion B'. The disk C has an arm c' by means of which it can be adjusted through the medium of gearing c<5>, c<6>, c<7>, c<8> relatively to an arm b<1> fixed to the gun-cradle. A second arm c' having a segmental piece c<4> is pivoted to the cradle co-axially with the pivot c and is adjustable relatively to a second arm on the cradle by turning a band-wheel c<9> in the same way as is the arm c<1>. The sight - carrier D has a segmental guide d<3> engaging with the segmental piece c', and depending lugs d' supporting a pivot d<5> co-axial with the pin c and cut away to receive an arc-shaped projection e on the arm e<1> of a sight-lever E connected to a combined ranging and pointing gear B<3>. The invention may be applied to a sight in which the pointing-screw is arranged vertically.
