There are 2 movements inside this clock. The first one is for the 8 day time and strike #89, every half hour it dings on 4 bells and on the hour counts out the hour. The second movement is for the Sonora chimes, #90.
Seth Thomas bought the rights to use Son. Ora chimes in his clocks in 1912 from the Sonora Chime Company.
After "tinkering" so they would fit in clocks he began to use them. Inside is a wooden box that holds the 4 bells and acts as a sounding box for the bells. There are 5 hammers, 4 are for the Westminster chimes on the quarter hour and the 5th hammer strikes the hour. Please see video below images for demonstration of the chime sound.
