This clock is a Chinese copy of a double fusee clock.
There is a large mainspring in the barrel on the bottom. To wind the clock, you wind the chain onto the cone in the middle of the movement. The theory behind the cone is that when the clock is nearing the end of the weak and the mainspring is running out of power, it provides the same amount of power to the mechanism using an adjusting ratio.
This is the front of the mechanism with the striking parts attached.
In this picture you can see the pendulum and winding arbors. This clock you wind from the back.
