Blaxland clock conservation
The Blaxland clock was made by London clock maker, Devereux Bowly, in the early 1700s. It is a striking clock that sounds a chime at the full and half hour.
The clock is powered by a fusee system and features a solid pallet type recoil escapement fitted with a brass pendulum. The back plate of the movement is decorated with hand engraving. The dial is fitted with English style hands and there is a small window in the dial below the 12 o'clock indicator, revealing a mock pendulum.
Specialist horological conservator Peter Bucke closely examined and documented the condition of the clock mechanism and its function. To ensure preservation of original form, function and previous repair methods, the movement was completely disassembled and all parts were thoroughly cleaned and inspected for wear.
The time side fusee arbor bush on the front plate was found to be faulty and unsafe to operate under normal conditions. A new bush was manufactured and fitted to ensure safe winding operation and the clock mechanism was reassembled and lubricated with fine synthetic watch lubricants. Minor adjustments were made to the strike sequencing and escapement system to ensure accurate operation.
