Summary
Clock mechanism. The main mechanism for driving the mechanical clock in the tower of the stable block of Penrhyn Castle, consisting of a wrought iron frame containing the anchor escapement, the striking mechanism, the transmission to the clock faces (via an intermediate mechanism, q.v.) and two wooden winding drums, one for the time and one for the strike. The winding drums have steel cables passing via two pulleys each (attached to the building) to the weights which drop down a shaft in the building. There is also a steel bar connecting the mechanism to the pendulum, which is mounted on the building alongside the mechanism. A circular brass monitor plate with a simple brass hand is provided, to allow adjustments to be made to the time displayed. The main frame is painted green and the metal parts are mostly bright.
