Abstract: A hitch, particularly of the tractor-operated type for supporting a trailer on a railway car, has a pair of jaws adapted to clamp the upper portion of a trailer kingpin, and an additional manual locking device for holding the kingpin in the trailer supporting plate of the hitch. The manual locking device includes a locking plate located beneath the kingpin and pivoted to the supporting plate and extending forwardly of the kingpin. The forward end of the locking plate has an upturned ridge or wall. A locking handle supported on the bottom of the supporting plate is adapted to slide forwardly to engage the bottom of the locking plate and move it upwardly. In this position the upstanding wall on the locking plate is juxtaposed to the lower portion of the kingpin to prevent it from moving out of the supporting plate.

Abstract: A tractor-operated hitch for supporting a trailer on a railway car is provided with a manually operated locking device for the trailer kingpin, in addition to the usual kingpin clamping jaws. The locking device includes a shaft or disc rotatable in the bottom portion of the supporting plate of the hitch below the jaws and has a C-shaped rim extending round the bottom of the kingpin. The locking device is turned by a handle so that the rim blocks the opening in the supporting plate through which the kingpin enters and leaves the supporting plate. The handle is arranged so that it can be operated fully only when the jaws are closed and locked, and thus provides a warning if the jaws are not locked closed.
