Locking end actuating mechanism for railway hopper car doors

A railway hopper car having a door hinged at its upper end to said car for outward swinging movement of its lower end to an open position and a keeper on said lower end if said door, the improvement of

• a latch mechanism on said car adjacent said lower end comprising:
• a bracket on said car,
• a latch member having a keeper engaging portion in the closed position of said door extending vertically and blocking outward movement of said door,
• means pivotally mounting said latch member above said keeper for clockwise and counterclockwise movement,
• actuating linkage for said latch member including a first toggle link pivotally connected to said latch member,
• a second toggle link including means pivotally connecting the same to said first toggle link,
• means pivotally connecting said second toggle link to said bracket,
• an unlocking lever including an upright arm, said lever being pivotally connected to the pivotal connecting means of said toggle links,
• said lever including a second arm in the loading position blocking pivotal movement of said toggle links, and operating means exerting an upward thrust on said upright arm, thereby pivoting said second arm to an out-of-the-way position whereby said toggle links are pivoted, thereby swinging said latch member in a clockwise direction whereby said keeper is released from said keeper engaging portion to permit movement of said door to said open position.
