Title: Improvements in Instruments for use in connection with Anti-aircraft Gunnery-an Instrument for Measuring the Deflection and Angle of Sight Correction, with Appliance for Showing the Fuze Indication Corresponding to the Predicted Position of Target.
IPC: F41G5/08
Filed: 1916-08-05
Abstract: 125,455. Barr & Stroud, Barr, A., and Stroud, W. Aug. 5, 1916. Computing-scales and calculating - apparatus. -Relates to apparatus for determining the corrections to be applied to sights of anti-aircraft guns to correct for speed of target. Assuming the target to be travelling horizontally at a height H with a known speed V, the components of the speed V in and perpendicular to the vertical plane of sight are, according to this invention, determined by an observing-instrument and the results obtained are modified in accordance with the height H and angle of sight to give the angle of lead in the vertical plane and the transverse deflection respectively by two surface cams, shaped longitudinally in accordance with the height and circularly in accordance with the angle of sight. A third surface cam may be provided to give fuse times. In the construction shown in Figs. 1, 2, 3, and 4, the rotary head 5, which elevates the observing telescope to follow the target, also, through suitable glaring, turns the surface cams 28, 29, 34 through the same angle. The cams are moved longitudinally to set for the height by a screw 36. In the principal plane of the telescope but not moving with the telescope is a transparent plate 9. Fig. 1, having on it a line which by rotating the plate in its own plane by a working head 13, Fig. 2, can be set parallel to the flight of the target. The working head 13 also rotates, through the same angle, a bevel wheel 15 carrying an eccentric pin, the eccentricity of which can be adjusted for different speeds, which engages two slotted slides 24, 25 which are thus set at a distance from the centre B proportional to the components of the speed. The movements of the slides are communicated to the lower ends of levers, one of which 50 is shown in Fig. 4. The position of the fulcrum 47 of the lever is changed by the surface cam 28 acting on a radial rod 44 and lever 45. The reading of the upper end L<1> of the lever 50 on scale 51 then gives the desired sight correction. The fuse cam 34 is further rotated an amount corresponding to the angle of lead in the vertical plane by differential gear 30, 31, 32 and a drum 35 to give the corrected fuse indication. The velocity of the aeroplane may be measured by providing a graduated scale parallel to the line on the plate 9 and determining the time the image takes to pass over a given angular interval, or the given angular intervals transversed in a given time. Specifications 1510/11, [Class 97 (i), Optical systems &c.], 4651/15, and 125,588 are referred to.
