Abstract
A mechanism with two moving parts to act as a 120.degree. indexing or escapement drive using a rotating member and a pivoting arm which are shaped to act together with a closely defined geometric relationship. As an escapement, a wheel, provided with three acting points or pins, will have a 120.degree. escapement motion for each oscillating cycle of a pivoting escapement arm. As an indexing drive, the same basic parts, aided by drive and backup means, will act in reverse: the oscillating pivoting arm is driving or indexing the wheel 120.degree. per each oscillating cycle wherein the driven angle per each half cycle of oscillation could vary between an equal 60.degree.-60.degree. proportion and the other extreme of a 120.degree.-0.degree. proportion. The positive tie-in of the wheel and pivoting arm throughout the full oscillating cycle permits the use of the mechanism in either direction as an escapement or indexing drive or a combination of both.
