Completing Clock B
View through CrossRef
Abstract
Charles Frodsham & Co. completed the work on Clock B that finalised its aesthetic and enabled it to run effectively in a sealed case with minimal human interaction for very long periods. This chapter documents their work on the clock and discusses their choices for implementing modern materials, such as Polyetheretherketone (PEEK) as bushing for gold pivots in the grasshopper escapement. It presents the reasoning for changing Burgess’s original method of driving the clock, which is found on Clock A (also known as the Gurney Clock). Instead of using a weight on a Huygens endless chain with motorised rewind, the team elected to use an unobtrusive weighted arm with electrical rewind to drive the clock.
