Some Theoretical Notes on the Detached-Lever Escapement
Abstract
This report presents a continuation of the first detailed mathematical analysis made on a detached-lever escapement timing device. The model studied was based on the T5E1 pin-lever escapement, designed primarily for ordnance applications. Although good quantitative results evolved from the original study, subsequent work suggested that the model was not capable of simulating certain characteristics of the detached-lever escapement. For example, this type escapement often had a torque sensitivity characteristic (frequency vs driving torque) that was concave upward. Further mathematical analysis has resulted in minor but apparently significant changes to the original model, indicating the feasibility of predicting the performance of an escapement more accurately.
