The clock has a unique arrangement for the weight and movement drive. The rope actually loops though the movement which allows for it to be much longer than if it was just attached to a weight and run over the drive pulley.

By creating a loop in the drive rope it is almost twice at long which cuts down on the amount of times you have to wind the clock. One more thing I discovered is that the clock plays its tune every four hours rather than on the hour as must clocks do.

Very old rope
