Copper lifting pressure bell

[Copper lifting pressure clock]

Copper lifting pressure clock, France, 19th century, with a height of 53cm, a width of 30cm, and a thickness of 20cm
A four-pillar copper pavilion is mounted on the marble base, and the eight legs of the square bell body are just caught in the straight slots opened inside the four corner copper pillars of the pavilion, forming a sliding track for the clock body to slide up and down. This clock has no winding and uses the gravity of the clock itself as its power source. In the middle of the front and rear columns on the right, there is a straight rack that engages with a semi exposed gear on the right side of the clock body. This gear is equivalent to the head wheel on other clocks and watches. When the clock body is lifted to the top, the clock body falls due to gravity, and the gear prevents the clock body from sinking due to its engagement with the rack. This dynamic and static action generates power, driving the timing system within the clock body
When using, raise the clock body to the top, which starts the timer. After 6 days, the clock body drops to the base, and then raises it in a circular motion.
