Gravity actuated container lock

A lock for a container having a hinged lid comprising a shaft having opposite ends, said shaft being adapted to be secured to a container on the upstanding container side opposite the lid hinge, said shaft journaled for rotation about its axis, a locking bar removably secured to said shaft and rotatable about said axis with said shaft between a locked position and an unlocked position, a lock lever secured to said shaft and movable with said shaft and said locking bar between said locked position and said unlocked position, and a roller mounted on a track over said lock lever for motion into and out of a lever lock position, said shaft being held from rotation when said roller is in said lever lock position and said locking bar is in said locked position, said locking bar being free to move out of said locked position when said roller is moved from its lever lock position, said lock lever and roller and rod being positioned in a box secured to said container side, one end of said shafts being journaled in said box, the other of said shaft ends being journaled in a bracket secured to said container side, said box and bracket being spaced apart, a pair of spaced apart locking bars being secured to said shaft ends and a blocking bar extending between the distal ends of said locking bars, said track comprising two pair of spaced apart rods secured to opposite side walls of said box, respectively, said roller being positioned between said rods of said pairs and extending between said opposite walls.
