How to Stop my wall clock from chiming

I received a grandfather wall clock as an anniversary gift. It says that it is made by the Boston Clock Company. It is a Manor House model #6056. It was purchased at JCPenny store in 2005. I was wondering how to stop the clock from chiming. It wakes in the middle of the night. No censor is visible, nor is there a switch as many clocks have. It has one C cell battery. There are two small wires that come from the compartment were the battery is and go into the chime. If I were to remove these, would I damage the rest of the clock, or stop the movement of the pendulum?
Thank you for your time. You are my last hope!!
