Input: pink shaft having rotary reciprocating motion.
Three identical teeth-uncompleted gears (in green and orange) are keyed on the shaft at different angular positions (the blue gears have the same angular position).
Output three rack-sliders (in blue and yellow). They have linear reciprocating motion with dwells. Their displacements (stroke lengths) are the same but the two blue rack-sliders move forward sooner than the yellow one. The latter moves backward sooner than the two blue rack-sliders.
