Recoil escapement

Escapement mechanism This is a very well-known recoil system devised by Nicklaus Felix Pflueger in 1755 to replace the verge escapement which no longer delivered satisfactory results. Two levers driven alternatively by the wheel teeth are pivoted separately on a special axis. Hardened steel plates are fitted to their ends. By constantly resting on one another, they transmit their reciprocal movements via a roller device. They drive two right-angled rods; the end of the second rod is pivoted on the stem of the pendulum, restoring the lost power to it.
