ABSTRACT:
A device for mechanically limiting the travel of a moving object along a path parallel to a travel rack bar. The ends of the travel rack bar include narrow extensions that come within a pair of elongated members of a moving rack member that are kept at a cooperative spaced apart relationship with respect to each other. The travel is accomplished through a pinion gear that is meshed with the travel rack and when it reaches the end of the narrow extension it pulls in the spring loaded moving members thereby maintaining the meshed engagement of the pinion gear at all times with either the rack member extension or the moving member.
