Abstract

An improved female connecting member for an articulated connector has a ring seat for a ring within an annular groove for contacting the male member of the connector, which female member has an improved undersurface passage for a probe to provide greater access to the ring-seat undersurface and more mechanical leverage to dislodge a worn ring seat; and, in an alternative embodiment, a structure and tool are provided for removal of a ring-seat from the exposed upper ring-seat surface.

Claims3

Dependent claims

In an articulated connection for joining adjacent railcars,

said articulated connection having a male connecting member and a female connecting member with an open end, an annular groove with an outer groove wall, a hub with an upper surface generally centrally positioned in said groove, and a ring seat positioned in said groove about said hub,
a ring positioned on said ring seat in said annular groove,
said male connecting member secured to an end of one of the adjacent railcars and the female connecting member secured to an end of the other of said adjacent railcars,
said male member adapted to be received in the open end of said female member to nest on and be supported by said ring on said ring seat in said annular groove while allowing horizontal and vertical movement between said male connecting member and said female connecting member,
a ring seat ejection arrangement for said ring seat in said female connecting member,
said annular groove having a vertical axis through said hub and normal to said floor,
said ring seat having an outer top radiused surface, and undersurface contacting said floor, and an outer perimeter, said ejection means comprising:
at least one ring-seat slot radially outwardly extending from said ring-seat top radiused surface,
a tool assembly having a contact plate, a grasping arm with an upper end and a finger for each said ring-seat slot, and a fixture,
said plate seated on said hub upper surface,
said fixture having an aperture for each said grasping arm and a central throughbore with a threaded sidewall,
each said grasping arm in a fixture aperture moveable to position its respective finger in a radially extending slot and securable in its respective fixture aperture at its upper end,
a bolt with a threaded shaft matable with said throughbore sidewall, said shaft having a lower end to contact said plate and to move said fixture, said arms and said ring seat vertically upward as said bolt is threaded into said throughbore to provide a uniform mechanical force to said ring seat for its removal from said annular groove.
