An Austrian universal compensation device invented by Lieut. Joseph Von Peichlof the Austro-Hungarian Navy in 1888, Patent 10, 101. A number of Peichl correctors were purchased for trial in the Royal Navy but did not find favour and were eventually discontinued.
Bowl- Diameter6.25" (15.9cm) Brass, with expansion chamber at base. Inside of bowl painted white with a black painted lubber line. A filler plug is provided at centre of verge glass and another in the brass verge ring, a card lifter mechanism is also fitted to verge ring.
Card- Diameter 5.75" (14.6cm) white painted metal card with black markings, graduated quadrantally in degres and to 1/4 points, unpainted float dome at centre.
The principal features are the means for carrying all correctors close to compass within the limits of the gimballing. A heavy gimbal ring carries a horizontal framework, partly wood and partly metal, in centre of which bowl is mounted. A metal framework is suspended from the underside and this carries a vertical magnet for correcting heeling error. Also there are four tubes with screw caps for carrying the magnets for correcting the semi-circular deviation. The horizontal framework is in two sections and between them 64 soft iron rods are carried, for correcting quadrantal deviation. The rods are arranged in two layers, one mounted on upper section, the other on lower section of horizontal frame. When in neutral position all their inner ends are equidistant from centre of compass and no effect is produced. To correct quadrantal error the two sections of the horizontal framework can be rotated by means of a key and rack work gearing, which causes the two sets of bars to revolve about the centre in opposite directions until they form an ellipse.
The key for operating the quadrantal correctors is on one side of framework, with a graduated scale on the other.
