A fifth wheel type hitch adapted for engaging a king pin of a trailer comprises a hitch head with downwardly opening pivot saddles which are pivotally supported on pivot bearings on a hitch base such that the hitch head pivots fore and aft relative to the hitch base. Outer portions of the pivot bearings are preferably formed from polyurethane. Latches, secured to the hitch head adjacent each pivot saddle, biasingly engage the pivot bearings when the hitch head is supported on the hitch base to prevent the hitch head from being separated therefrom. Lift handles connected to each latch are graspable by a user and pivotal to advance the latches to an unlatching position such that the hitch head can be separated from the hitch base and such that further lifting on the lift handles lifts the hitch head off of the hitch base. The hitch head comprises an intermediate pivot frame, in which the pivot saddles are formed and a coupler assembly which is adapted to releasably engage the king pin. The coupler assembly is pivotally secured to the intermediate pivot frame and pivotal from side to side relative thereto. Side to side pivoting of the coupler assembly is damped by one or more shock absorbers.

[ What is claimed and desired to be secured by Letters Patent is as follows:] [1.] A hitch for engaging a hitch pin and comprising:a) a hitch base having a pair of upstanding support arms with pivot bearings mounted on upper ends thereof;b) a hitch head comprising a coupler assembly connected to an intermediate pivot frame; said coupler assembly adapted to releasably engage the hitch pin; said intermediate pivot frame having a pair of downwardly opening pivot saddles; said pivot saddles removably supportable on said divot bearings such that said intermediate pivot frame is pivotal fore and aft relative to said hitch base; andc) a pair of latches each movably mounted to said intermediate pivot frame proximate one of said pivot saddles and biasingly urged from a retracted position to a latching position such that when said latches are positioned in said latching position said latches engage said hitch base and prevent separation of said intermediate pivot frame from said hitch base and when said latches are positioned in said retracted position said latches do not engage said hitch base such that said intermediate pivot frame may be removed from said hitch base.
