Abstract: A device is provided for manually maneuvering a set of switch points, the device includes a housing which is intended to apply a force at a location of a set of rail switch points in order to move the set of switch points relative to the housing from a first switch points position to a second switch points position. The device also includes a guided member for controlling the set of switch points, which can be moved relative to the housing, a guiding member, which can also be moved relative to the housing, a transmission mechanism for driving the guided member in one direction when the guiding member moves in a first direction. The guiding member is capable of being moved in a second direction, opposed to the first direction, while the guided member remains fixed relative to the housing.
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.
Abstract: A railroad switch mechanism wherein the switch points of a track switch are moved between normal and release positions by a switch machine connected to the switch points by throw rod, lock rod and detector rod assemblies which are adjusted to have predetermined lengths. The lock or detector rod assemblies have couplings which enable temporary disconnection from the switch points when testing to verify whether the operation of the switch to normal and reverse positions is within an allowable range of variations with respect to the stock rails with which the track switch is associated without affecting the adjustment of the length of the assemblies and requiring long and costly readjustment after the completion of testing.
