The mechanism of this captivating Congreve rolling ball timepiece is considered to be one of the most fascinating ever invented. Patented by Sir William Congreve in 1808, it reflects the aspiration of clockmakers to find an alternative to the pendulum as an escapement regulator. In this interpretation of Congreve's ingenious design, a steel ball runs down the inclined zig-zag track where it trips the escapement, reversing the angle of the tray and causing the clock's hands to move forward corres

Incline Gravity Clock https://www.physicsfunshop.com/search?keywords=gravity clock Powered by gravity this clock has no batteries or mainspring- however, once each day the clock must be picked up and placed back at the top of the ramp. As the clock rolls down the incline (here 12 hours are captured in time-lapse of 24 seconds), gravitational potential energy is translated into the kinetic energy of the moving clock gear train and oscillating balance wheel. The clock face and mechanism hang suspe
