Device for erecting and stabilizing a gyro vertical

Device for erecting and stabilizing of a gyro vertical, comprising a disc arranged on the gyro housing and perpendicular to the gyro axis, said disc being driven in the same sense as the gyro rotor but at a reduced rate as compared thereto, and having at least one guideway, in which a mass is movably guided, the guideway being arranged such that the disc with the mass is balanced with respect to the gyro axis, when the mass abuts the rear end, with respect to the rotary movement, of the guideway, and that the movement of the mass in the guideway causes an erecting torque, when the gyro spin axis deviates from the vertical direction observed,

• characterized in

• 88;
• 128) around the gyro spin axis (16) to an end (60,62;
• 108,112) located near the gyro spin axis (16), said guideway (40,42) comprising an arcuate guideway portion (44,46) curved around the gyro spin axis along the periphery of the disc (12), and a straight guideway portion (52,54) joining the end (48,50), leading with respect to the rotary movement, of the arcuate guideway portion (44,46), said straight guideway portion passing the gyro spin axis (16) at a small distance, and the straight guideway portion (52,54) ending in a u-shaped, inwardly curved guideway portion (56,58).
