Device for adjusting the position of a pallet-stone mounted in clockwork escapement pallets

摘要

The striker tooth is gripped by a fixed jaw (76) and a moving jaw (78) whose position is controlled by a cam lever (88) and spring (86). The anchor is gripped by a lever (54) and screw (64) on a trolley (34) moved by a micrometer adjustment (36). Integral heating (70) releases the tooth glue, and adjustment (36) is followed by microscope and measured by a comparator (38).
