The grasshopper escapement is an unusual, low-friction escapement for pendulum clocks invented by British clockmaker John Harrison around 1722. An escapement, a part of every mechanical clock, is the mechanism that releases the clock's gears to move forward by a fixed amount at each swing of the pendulum.
