Abstract
An apparatus for connecting a kingpin of a gooseneck or fifth wheel trailer to a towing vehicle includes a fifth wheel hitch having a hitch platform with a hitch head slidably mounted on the rails of a base platform; an articulating mechanism to displace the hitch platform to and from a forward towing station and a rearward towing station; and a latch having a latch pin to automatically lock the hitch platform at the forward and rearward towing stations and also having a biased spider device to automatically prevent the latch pin from re-locking the hitch platform when the hitch platform is released from a towing station until after the hitch platform has been displaced away from that towing station.
