The Riefler escapement is a mechanical escapement for precision pendulum clocks invented and patented [1] by German instrument maker Sigmund Riefler in 1889. [2] It was used in the astronomical regulator clocks made by his German firm Clemens Riefler from 1890 to 1965, [ 3 ] which were perhaps the most accurate all-mechanical pendulum clocks made.
Animation of an anchor escapement, one of the most common escapements used in pendulum clocks . The escapement is a mechanical linkage that converts the force from the clock's wheel train into impulses that keep the pendulum swinging back and forth. It is the part that makes the "ticking" sound in a working pendulum clock.
Sigmund Riefler was born on 9 August 1847 to Magdalena and Clemens Riefler. He studied mathematics, geodesy and mechanical engineering at the Technical University of Munich, and then physics and astronomy at the University of Munich. From 1870 he worked as an engineer in the Royal Prussian Land Survey, surveying land in Schleswig. [3]

Law sought to limit monetary expansion and maintain price stability, by using land as a measure of, and collateral for, real activity. [4] Smith then substituted short-term self-liquidating commercial paper for Law's production proxy, land, and so the real bills doctrine was born.
Some further discussion of Riefler as a horologist would be helpful too. For example, a discussion of Riefler's watch escapement. — Preceding unsigned comment added by 203.216.97.231 ( talk • contribs ) 01:20, 4 May 2007 There is a link to the article on Sigmund Riefler that does provide background.
