Railroad switch mechanism

A control assembly for a railroad switch mechanism having a switch machine and a railroad track switch connected thereto via said control assembly, which control assembly avoids the need for readjustments after testing, said control assembly comprising a rod assembly movable with said track switch and providing a rigid connection beween said track switch and said switch machine of adjustable length, coupling means in said rod assembly having an opening, a member removable from and replaceable in said opening for releasing said connection so that the adjustment of said connection established by said rod assembly upon replacement of said member in said opening is quickly reestablished thereby reducing the time required for testing to verify the operation of said track switch, said rod assembly being provided by a detector rod assembly, said detector rod assembly comprising a detector connector rod connected at one end thereof to the switch points of said track switch and via said releasing member to the detector bar of said switch machine, said coupling means including a collar having an annular groove defining said opening, said connector rod being connected to said collar, means retaining said collar in longitudinal sliding relationship therewith, and a replaceable retaining member disposed in said groove and engageable with said retaining means for releasing said collar and connector rod for sliding movement when removed from said groove and maintaining said rigid connection when disposed in said groove.
