A ratchet arrangement is operable in both directions to provide the desired proportional spacing increments, with rotation of a ratchet wheel in the clockwise direction being controlled by engagement of an associated pawl with one of a plurality of stop engaging surfaces of a control member which sets the number of proportional spacing increments desired.
