Abstract: An automatic latching assembly is provided for retaining vehicle bodies upon conveyor carriers during conveyance into and out of treatment baths. The assembly includes a carrier having latches mounted thereon which selectively engage the vehicle body securing it to the carrier. The latches comprise pivoting hooks rotatably mounted upon the carrier. Generally, gravity actuates pivoting of the hooks, biasing them into latching orientations. Unlatching orientations are achieved by a stationary, upward biasing cam operating upon the hooks. A downward biasing cam aids in the gravity actutation of the hooks into the latching orientation. The assembly selectively, automatically secures the vehicle body to the conveyor carrier, or releases it therefrom, as desired during transport of the vehicle body by the conveyor.
