ABSTRACT:
A railway Type H tightlock coupler locklift assembly for coupling railway cars comprises a Type H rotary locklift toggle, a Type H rotary locklift lever, and a rivet connecting the rotary locklift toggle to the rotary locklift lever. The Type H rotary locklift lever further comprises a standard flange or finger for operatively engaging a coupler operating rod and a second opposing flange or finger that abuts the coupler operating rod. The second opposing flange or finger prevents unintentional rotary motion of the rotary locklift lever by acting on or abutting against the locked operating rod, thereby preventing unintentional uncoupling of the railway cars when coupler components of such cars are struck by flying debris.
