The first thing you notice is the steady tick-tock of the clock mechanism as it keeps time the same way it has for over 100 years...

The clock mechanism was built by the E. Howard Clock Co. in Waltham, Massachusetts. The machinery was installed on October 11th, 1892 with the clock faces installed the following week.

To keep good time, the clock mechanism is wound once a week at a uniform time. 90 turns of the crank are needed to wind the timer -- lifting the weights that descend several stories below the clock level.

   

The other part of the mechanism is the striker, which rings the bell. The striker must also be wound each week .. 330 turns!

On the right hand side of this picture you can see the wind vanes that regulate how fast the striker mechanism rings the bell.
