Title: Improved device for the mechanical determination of firing data for firing at movingtargets
IPC: F41G5/00
Filed: 1937-11-03
Abstract: 498,212. Gun-sights. OESTERREICHISCH UNGARISCHE OPTISCHE ANTSTALT C. P. GOERZ GES. Nov. 3, 1937, No. 30164. Convention date, Nov. 10, 1936. [Class 92 (ii)] [Also in Group XIX] In determining the data for laying a gun for firing at moving targets in a manner similar to that described in Specification 343,011, namely by the mechanical solution of the equation t=az/b-z where t is the time of flight, z the range of the point of impact, and a and b are parameters, one end of a screw-threaded shaft is connected by a universal joint to a member 19 which is moved in space to represent the target velocity while the other end of the shaft works in an internally threaded sleeve 15 which is universally jointed to the axle of a drum 13 bearing a graduation spiral 13a, the drum being thus rotated in proportion to the distance b between the joint 18 and the sleeve 15. In the diagram the target at the moment of firing is at point 95 and at the moment of hit is at point 91. If similar triangles 92a, 91, 95 and 90, 92, 96 are constructed, the velocity of the target v being 90, 92, 92a, 91 being b, 90, 96 being av, and 92a, 91 being z then av/tv = b-z/z or t = az/b-z. In order to determine the line 90, 96 pointers 33 and 33<1> are adjusted on scales 34 and 34<1> to indicate the velocity of the target. Through spur gears 30, 29 and 29<1> and bevel gears 27 and 27<1> this motion operates threaded spindles 25 and 25<1> which move nuts 26 and 26<1> through a distance proportional to the velocity. Pointers 35 and 35<1> are now adjusted into parallelism with the line of motion of the target and through gears 23, 31 and 23 the direction of the spindles 25 and 25 are brought into parallelism with the direction of motion of the target. The scales 34 and 34 move with the pointers 35 in order that their readings may remain true for any adjustment of pointers 35. Meanwhile by rotation of the crank 3c a carriage 2 carrying the drum 13 is moved by a worm gearing in a direction parallel to the gun barrel. A target distance scale x is also moved by the crank 3c through a worm gearing 3b and a cam 5. When the range x of the target just measured registers with the graduation spiral on the drum 13, an index z on the carriage indicates the range of the point of impact on a fixed scale z. The angle now formed between the shaft 18, 15 and the axis of the gun gives the angle between the line of sight and the line of hit. The shaft works in slots in two brackets B<1> and B<2> pivoted at right-angles. The axles of these brackets are connected by cranks and levers to the sighting telescope to displace it through the angle. The casing 21 of the target velocity mechanism is connected to an ordinary height of fall attachment to allow for the trajectory of the projectile. The cam 5 is provided to make a correction for the approximate character of the equation t= az/b-z. The position of scale x can also be adjusted by a double threaded spindle 11 to allow for change in muzzle velocity of the gun.
