Lot Essay

The Inclined Plane Clock, also known as Rolling Drum Clock, was invented around 1580. The basic principle of such a clock is the use of a counterweight linked to the centre wheel of the movement by a bar. Thus the natural tendency of the clock to roll down is stopped and permits it to move only as the counterweight is gradually lowered when the escapement releases the train of wheels to which it is attached.

To wind the movement, the clock needs to be rolled up the incline and will then descend over a period of a week while the dial stays in the upright position.
