A safety and assist mechanism for a flip chute hingedly connectable to a mai n chute for movement about a transverse hinge axis between a stored position over the main chute and a working position as an extension to the main chute . The mechanism has a lever rigidly securable to the flip chute to rotate with the flip chute about the hinge axis. A spring is connectable to the lever an d to the main chute to generate a moment about the hinge axis contra to a moment generated by the weight of the flip chute
