Patent GB-386329-A (GB)
Abstract: 386,329. Bomb-dropping sights. ESTOPPEY, G. L., 411, West 1st Street, Dayton, Ohio, U.S.A. April 8, 1931, No. 10400. [Class 92 (ii).] A bombing sight 10 comprising an upper sighting member 14 and lower sighting members 12, 13 is universally suspended from a bracket 5 on the aircraft and the transverse wind correction is automatically applied to the sighting member 14, as by means of a screw 81 and gearing 71, 72, when the bracket 5 is trained round a fixed post 1 to bring a bar 60 into register with a bar 52 set to the desired course of the aircraft. The lower sighting members 12, 13 are carried by nuts 23, 20 engaging oppositely threaded parts of a shaft 15 which is adjusted longitudinally to correct for air resistance by turning a nut 38 by means of a drum 36 graduated in terms of " terminal velocity " and aircraft speed. The longitudinal component of wind is also conveyed to the shaft 15 by turning a screw 17 within the nut 38 .by a hand-lever 41. The sighting member 12 is frictionally mounted on the nut 23 and is first roughly adjusted to suit the altitude and air speed shown on a scale 136 and the target is then followed by operating a hand-wheel 31 and gearing 28, 26 for a time interval determined by the movement of a hand 95 previously set to the time of fall on a scale 127 and set in motion by a clock, Fig. 6, automatically started on moving the hand-wheel 31. When the hand 95 comes into view in a window 131, the motion of the hand-wheel is stopped and the sighting member 13 is then in position for releasing the bomb when the target is in line with this sighting member. The clock mechanism is so arranged that the preliminary movement of the hand-wheel 31 to set the sighting members to starting position serves to wind the clock through a ratchet 114, Fig. 6, and bring a catch 118 against a lever 105 which is operated to release the clock mechanism as soon as the hand-wheel 31 is rotated in a direction to cause the sight 12 to follow the target. The direction bar 52 is mounted for movement round the portion 4 of the bracket 5 by bodily movement of a hand-wheel 59, rotation of which serves to move the whole sight 10 round the spindle 1 to bring the bar 60 into register with the bar 52. A resistance 62 traversed by a contact arm 61 moving with the hand-wheel 59, and in circuit with a voltmeter viewed by the pilot, serves to indicate the deviation between the bars 60, 52. The sight is stabilized about the universal joint 8, 9, by a weight 45 and by dashpots 47, 48 arranged at right-angles to one another. 386,329.
