QUESTION: Yes it is striking and chiming correctly and yes there is space between the hour hand and minute hand. Thank you so much.

Answer
This is an unusual time for the clock to stop. The face may have to be removed to see if something in the levers is causing the clock to stop. The other possibility is a bent hand shaft. The way to check for this is to turn the minute hand backwards and watch the shaft from the side. If the hand shaft seems to go up and down as you turn the hand the shaft is bent, causing friction, and will need to be straightened out.
