Abstract: The invention concerns a tilt-compensating indicator device for a compass (100) comprising a magnetic field detection device (20) which is mounted on a conical bearing (7) and is accommodated in a housing (100') of the compass (100). The indicator device (30) is rotatably mounted on the magnetic field detection device (20) by means of a receiving bearing (8,10) whose bearing shaft (8), accommodated in bearing elements (10) of the magnetic field detection device (20), extends substantially at right-angles to the north-south direction of the magnetic field detection device (20).

Abstract: The present invention provides a compass comprising an at-least-partially-transparent housing having a top and a bottom, a vertically orientated, conical pivot bearing, and a magnetic detection means which is mounted on the vertically-oriented conical pivot bearing. The magnetic detection means thereby is capable of rotating in a substantially-horizontal plane. The magnetic field detection means is provided with a radially-extending, tilt-compensating, indicator device. The indicator device has at least one spacer element which is spaced from the magnetic field detection means, the spacer element projecting from the indicator device and being directed towards one of a top of the housing of the compass and a bottom of the housing of the compass.

Abstract: A tilt-compensating magnetic compass formed by a capsule enclosing a rotatable pointer to indicate direction and a rotatable magnetic-field detector provided with a permanent magnet. The detector, which is rotatable about an axis colinear with the axis about which the pointer rotates, orients itself with respect to the earth's magnetic field, the detector being tiltable to a degree depending on the inclination of the magnetic field and on the attitude of the compass with respect to the horizontal plane. The detector is mechanically linked to the pointer so that rotation of the detector results in a corresponding rotation of the pointer regardless of the degree of tilt, whereby the pointer accurately indicates direction. The linkage consists of a pin projecting from the detector and passing through a slot in a fork extending from the pointer, whereby when the detector tilts, the pin then shifts within the slot, but remains coupled to the fork to maintain the linkage without imparting movement to the pointer.
