HOLLOW TIE SWITCH ASSEMBLY

摘要

A hollow tie assembly for rodding associated with moveable trackwork (such a s in a switch or a moveable point frog) serves the function of a tie, houses and protects throw rods, lock rods and detector rods, is adapted to accommodate North American switch machines, and does not interfere with mechanical tampers. T he rodding is housed within two elongated and spaced channels which are held in predetermined spaced relationship. Switch plates straddle the flanges of eac h channel and the moveable rails or points are mounted on the switch plates. R od adapters and switch clip provide a sliding connection to the moveable rails or points. The rods are made of insulating material and the switch plates and associated components include insulation to avoid cross conduction between t he rails.
