Description:
In this model, a constant torque supplied by a heavy weight, is applied to the toothed escape wheel. The escape wheel transfers energy to the oscillating pendulum each cycle to make up for the losses due to friction. This three-tooth escapement is very old and can be found in the 17th century French book of de la Hire, Traite de Mechanique. The repiprocating mechanism was used to drive a log sawing machine back and forth as the three-tooth wheel rotated. It was also listed in the 19th century book of mechanisms by the American, Henry T. Brown. This escapement was used in the London clock at Westminister (Big Ben) for half a year until it was replaced by a gravity escapement. Its invention is attributed to the English clockmaker Edmund B. Denison in 1851.
