The grasshopper escapement is a low-friction escapement for pendulum clocks invented by British clockmaker John Harrison around 1722. An escapement, part of every mechanical clock, is the mechanism that gives the clock's pendulum periodic pushes to keep it swinging, and each swing releases the clock's gears to move forward by a fixed amount, thus moving the hands forward at a steady rate. The grasshopper escapement was used in a few regulator clocks built during Harrison's time, and a few others over the years, but has never seen wide use. The term "grasshopper" in this connection, apparently from the kicking action of the pallets, first appears in the Horological Journal in the late 19th century.

has abstract
| - El escape saltamontes (traducción literal del nombre original en inglés, grasshopper escapement) es un tipo de mecanismo de escape utilizado en los relojes de péndulo, inventado por el relojero británico John Harrison alrededor de 1722. El cometido de un escape es producir los impulsos periódicos necesarios para mantener el péndulo de un reloj en movimiento. Cada oscilación libera los engranajes del reloj, permitiendo que avancen en una cantidad fija, moviendo así las manecillas a un ritmo constante. El escape saltamontes se usó en una serie de relojes de péndulo construidos durante la época de Harrison, así como en algunos otros a lo largo de los años, pero nunca se ha utilizado ampliamente. El término saltamontes, posiblemente relacionado con el movimiento del mecanismo que recuerda al de las patas traseras del insecto, apareció por primera vez en el Horological Journal a finales del siglo XIX.
