ABSTRACT:
An escapement device has a latch plate interposed between an input and output shaft. The latch plate is pivotably connected to the input and output shafts. The latch plate has a shoulder which abuts a coaxially mounted gear ring. The output shaft is spring loaded to rotate in one direction. The input shaft can be rotated to disengage the shoulder of the latch from one of the gear ring teeth to allow the output shaft to rotate under its spring bias until the output shaft repositions the latch shoulder to reengage another one of the gear ring teeth.
