Suiter Swantz IP takes a look back at past inventions and inventors with our Patent Of The Day.
On this day in 1906, William Thomson and Francis Wood Clark were granted U.S. Patent No. 816,618 for a MARINER’S COMPASS.
This invention relates to an improved suspension for ships’ compass-bowls. This suspension is so constructed that the vibration caused by the ship’s engines, the roll or pitch of the vessel is taken up and softened before reaching the compass-card. The suspension is also so arranged that it gently resists but at the same time allows the compass-bowl to swing in every direction. We attain this all round equal cushion-like resistance by the lateral or torsion motion of tightening links and springs.
