Entry
Pivot with a ruby head (NG-MC-877-A on a wooden pedestal and two compass cards (NG-MC-877-B and NG-MC-877-C).
One card has a brass cap with the dab for the pivot beneath. The turning of the card is facilitated by the materials used, while the large area of friction of the ruby diminishes tilting movements at the same time. The card, which is damaged, slides inside an outer rim, which is graduated in degrees: this was to compensate for magnetic variation (the angle between true north and magnetic north). The second card (NG-MC-877-C) is of the same type, but the dab for the pivot is made of a red semi-precious stone, probably agate.
The first card (NG-MC-877-B) is a Kleman compass card adapted to George Stebbing’s (1775-1847) patent. The second was an improvement of Stebbing’s patent card by Jan Marten Kleman (1758-1845) himself.
