Title: An improved aiming device, more particularly for anti-aircraft guns
IPC: F41G3/00
Filed: 1931-03-16
Abstract: 374,930. Anti-aircraft gun sights. RHEINISCHE METALLWAAREN-UND MASCHINENFABRIK, ROMBERG, H., and OTTO, C., 195, Ulmenstrasse, Deren. dorf, D³sseldorf, Germany. March 16, 1931, No. 8027. [Class 92 (ii).] Relates to anti-aircraft sighting devices in which, after preliminary adjustments to suit-observed data, the act of laying the sight on the target automatically imparts to the gun the desired lead angle. The invention particularly relates to devices in which a telescopic rod d parallel to the sight g is universally jointed at d<1> to an arm b parallel to the gun, the free end of the rod being vertically adjustable for tangent angle of elevation and radially adjustable with respect to a plate e to suit the range, speed, and direction of flight of the target. According to the invention, the free end d<2> of the rod d is ball-jointed to a slide f<1> adapted for radial movement in a guide l which can be set by turning an indicator m into the direction of movement of the target, and vertically adjusted to suit the tangent angle of elevation by means of a screw operated by turning a graduated sector k into register with a pointer a<8>. Further, the plate e secured to the guide l carries curves, Fig. 7, which enable a pointer f<0>, Fig. 6a, on the slide to be set to a radius depending on the range and speed of the target. To effect this, the plate e is first turned until the radial line corresponding to the range registers with the pointer f<0>, the slide f<1> being then moved radially by rotating a pinion o<2> by means of a hand-wheel o until the pointer f<0> is on the curve corresponding to the observed speed of target. To prevent training movements of the gun from affecting the direction imparted to the guide l by the indicator m, the guide is connected to the training ring through a clutch q and gearing p<2>, p<1>. The sight is connected with the rod d by parallel-motion links h controlled by a link h<1> to keep the sight in a position convenient to the observer. Fig. 8 shows a modification in which the graduated plate is fast with the guide l the slide carrying a measuring edge fo<1> which is movable radially to register with the appropriate intersection between the range lines and the speed curves.

Abstract: 609,647. Calculating-apparatus. TERRAMARINE, Ltd., and THOMS, P. PERRING-. March 19, 1946, No. 8542. [Class 106 (i)] An instrument for use in determining the azimuth or true bearing of a heavenly body comprises a slidable plate 6, Fig. 1, having a series of latitude markings lying on a series of ellipses 14 graduated in degrees and a series of hour angle markings lying on a series of hyperbolµ 14 graduated in degrees and in hours. The arrangement is such that the minor axes of all the ellipses 14 lie on a common line corresponding to the meridian of the observer and all the hour angle hyperbolµ 15 have foci equidistantly on opposite sides of the meridian on the common line of the major axes of the latitude ellipses. The plate 6 is slidable over a fixed plate, not shown, which carries at two diagonally opposite corners declination scales which co-operate with cut-outs 16, 17 in the plate 6. The plate 6 is also provided with a slot 7 which receives a rotatable shaft which passes through the fixed plate and carries a compass rose, not shown, which co-operates with a compass rose marked on the back of fixed plate. A pointer 12 carried by a rod 11 which is slidably mounted in the rotatable shaft co-operates with the latitude ellipses 14 and the hour angle hyperbolµ 15. In use, the plate 6 is slid over the fixed plate until the declination of the heavenly body, as calculated from tables, is shown at the cut-out 16 or the out-out 17 depending on whether the observer's latitude and the calculated declination are of the same or different names. This positions the rotatable shaft along the slot 7, i.e., fixes the axis of rotation of the pointer 12. The rod 11 is then rotated and adjusted radially until the pointer 12 is over the intersection of correct latitude ellipse and the correct hour angle hyperbola, whereupon the azimuth or true bearing of the heavenly body may be read from the fixed or rotatable compass rise according to whether the observer is in a northern or southern latitude. The pointer or indicator 12 may vary in construction if desired and the fixed plate may be marked with data from which the declination of the heavenly body may be initially calculated.

Abstract: 771,398. Spring stop mechanism. NAAMLOOZE VENNOOTSCHAP HOLLANDSE SIGNAALAPPARATEN. March 24, 1955. No. 8601/55. Class 108(3). [Also in Group XXXIV] A stop mechanism mechanically prevents the continued rotation of a shaft 7 which, after starting from a definite initial position, has made a pre-determined number of revolutions. The shaft 7 is mechanically coupled through a spiral spring 5 to a bush 8 which is itself coupled through pin 11 to an arm 12 secured to a gear wheel 18, so that when rotation of the wheel 18 is not resisted, it may be regarded as rotatable in synchronism with the shaft 7. The gear wheel 18 is in constant mesh with a wheel 1 having a slightly different number of teeth, for instance 61, as compared to 60 for wheel 18, so that two toothshaped cams 3, 3A after a predetermined number of revolutions move across the path of a tooth-shaped tilting lever 15, mounted to rotate on wheel 18, and deflect the member 15 by flexing the spring 6, so that the shaft 17 tilts a lever 16, one or the other of the pins at its extremities thus being moved into engagement with the curved indentation 22A of resilient stops 14 or 14A. The stop thus resiliently arrests the shaft 7 first by tension in spring 13 and later by contraction of the coil spring 5.
