Title: Fire control apparatus for naval guns
IPC: F41G5/22
Filed: 1920-07-05
Abstract: 146,482. Krupp Akt.-Ges., F. Nov. 18, 1916, [Convention date]. Gyroscopic apparatus.-Relates to the distant gyroscope-control of the elevation of naval guns to ensure accurate firing when the ship rolls, and consists mainly in the provision of an electric transmitter at the observing station T where the gyroscope is situated and, connected to the transmitter, electric receivers at a control station II, and at the gun station III. The gyroscope is enclosed in a casing A which can be trained about a vertical axis; and the axle b<1>, b<2> which is stabilized by the gyroscope carries a sight B on one side and is geared on the other side to a transmitter comprising a coarse element C and a fine element E. These elements are set for range through the gearing shown by means of a milled head G in conjunction with a scale and pointer g<2>, g<3>, and the setting corrected, if necessary, for time lag in firing by means of a milled head H. The setting stabilized by the gyroscope is transmitted to receivers comprising coarse and fine elements X, P at the control station and T, T<1> at the gun station. The gun layer elevates his gun to make a mark t<4> connected to the elevating gear follow the pointer T<1>, and signals to the control station that he has done so; similarly the man at the control station follows the pointer P with a mark r<2> on a sector R. When the ship reaches the end of its roll in one direction, the marks r<2>, t<4> are left where they stand; and the gun is fired after the pointers P, T<1> have receded from the marks r<2>, t<1> and reached marks r<1>, t<3> at fixed equal distances away from the marks r<2>, t<1>, the firing mechanism being released by an electro-magnet t<6> when a switch T<7> at the control station is closed. The movements of the marks r<2>, r<1> and t<3>, t<4> and the closing of the switch T<7> may be performed by hand or automatically. The transmitter and its setting gear is so made that the setting imparted by the milled head G differs from the correct range setting required by a fixed amount corresponding to the distances between the marks t<3>, r<1> and t<4>, r<2> respectively. Hence the elevation of the gun is correct at the moment when it is fired. The pointer N of the control station is provided with a miniature imitation N<2> of the gun T<5>. Several stations may be connected together.
