Abstract
A mechanism is disclosed for actuating a switch guide beam swinging laterally between two or more fixed guide beam ends, in order to make a route selection for a beam guided vehicle. The moving guide beam pivots distantly of the primary fixed guide beam end to create a gap spanned by an intermediate suspended channel plate guide segment that provides substantially two equal lateral deflections to the moving vehicle for a route diversion in a storage yard or repair shop area. The mechanism for high speed or main line operation has two additional channel plate guide segments slidably guided at each end of the guide segment centrally affixed on the straddle beam and pivoted at the primary beam fixed end and the merge point on the radially moving swing guide beam to provide four substantially equal lateral deflections to the moving vehicle when a route diversion is required. The aggregation of moving guide beam elements mounted above the wheel rolling surface is actuated to select a route change by a geared motor driven sprocket mounted under the swing beam structure engaging a passive chain radially secured slightly below the wheel travel surface near the extreme end of the swing guid…
