Abstract
An apparatus is provided for moving a movable switch point a selected distance as a result of the throw of a switch machine. The apparatus includes an operating rod connected to and movable by the switch machine and a switch point adjuster mounted directly to the switch point and movable by the operating rod. The switch point adjuster has an elongated housing with a bore provided therethrough, in which the operating rod is disposed through the housing bore. The switch point adjuster also has first and second adjusting nuts that are adjustably secured to the operating rod on opposed sides of the housing, preferably by mated threading. The operating rod is movable bidirectionally through the housing until one of the adjusting nuts contacts the housing. In this way, lost motion of the switch machine may be compensated for. The adjusting nuts preferably have a head portion and a body portion, in which the head portion has a width greater than the width of the body portion. Thus, the head portions of the adjusting nuts are contactable with respective opposed ends of the housing. Alternatively, or in addition, the housing may have an interior ledge provided within the housing bore, and leading edges of the adjusting nuts which are disposable within the housing may contact the interior ledge.
