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.
Claims8
A railway Type H tightlock coupler locklift assembly for coupling railway cars comprising:
- a Type H rotary locklift toggle,
- a Type H rotary locklift lever having pivot hooks for rotatably receiving rotes of a coupler head, the pivot hooks defining a coupler operating rod eye for receiving a coupler operating rod, the rotary locklift lever also having a first flange for operatively engaging a coupler operating rod J-hook of the coupler operating rod and a second opposing flange, the first and second flanges formed integral with the pivot hooks of the locklift lever and extend outward in parallel relation from the pivot hooks, and
- a rivet connecting the rotary locklift toggle to the rotary locklift lever,
- whereby the second opposing flange of the rotary locklift lever abuts the coupler operating rod J-hook mounted through the coupler operating rod eye and over the pivot hooks and prevents unintentional rotary motion of the rotary locklift lever about the rote of the coupler head, thereby preventing unintentional uncoupling of the railway cars.
A railway Type H tightlock coupler locklift assembly for coupling railway cars comprising:
- a Type H rotary locklift toggle,
- a Type H rotary locklift lever having pivot hooks for rotatable receiving rotes of a coupler head, the pivot hooks defining a coupler operating rod eye for receiving a coupler operating rod, the rotary locklift lever also having a first flange and a second opposing flange, the first flange operatively engaging an operating rod having a diameter, the first flange and second opposing flange defining a recess, the recess sized to fit with the diameter of the operating rod, the first and second flanges formed integral with the pivot hooks of the locklift lever and extend outward in parallel relation from the pivot hooks, and
- a rivet connecting the rotary locklift toggle to the rotary locklift lever,
- whereby the second opposing flange of the rotary locklift lever abuts the coupler operating rod mounted through the coupler operating rod eye and over the pivot hooks and prevents unintentional rotary motion of the rotary locklift lever about the rote of the coupler head, thereby preventing unintentional uncoupling of the railway cars.
A railway car coupler locklift lever comprising:
- pivot hooks for rotatably receiving rotes of a coupler head,
- a coupler operating rod eye defined by the pivot hooks for receiving a coupler operating rod,
- a first flange and a second flange, the first flange operatively engaging a coupler operating rod, the second flange being adjacent the coupler operating rod, the first and second flanges formed integral with the pivot hooks and extend outward in parallel relation from the pivot hooks,
- whereby the second flange abuts the coupler operating rod and prevents unintentional rotary motion of the locklift lever and thereby prevents unintentional uncoupling of the railway cars.
