  • Compass having a course directing pointer
    Patent number: 4184267
    Abstract: A compass is provided with a course indicated pointer, rotatable about the same center as the compass card, and frictionally engaging the same. A mechanism, including a finger for catching the pointer, is provided for adjusting the pointer to any selected position, and, while doing so, braking the card so the action of the finger overrules the frictional engagement between the finger and the card.
