Claims7
In a pedestal side frame of the type having a downwardly facing jaw including a roof portion and opposed sidewall portions extending downwardly from said roof portion, a first lug located on one of said sidewall portions, a second lug located on the other of said sidewall portions opposite the first lug, a bearing adapter adapted to be received in said jaw including a first vertically extending channel for slidably receiving the first lug and a second vertically extending channel for slidably receiving the second lug thereby to retain the bearing adapter in the jaw, and, disposed between said jaw and said bearing adapter, an improved wear plate, comprising:
- a base portion abutting said roof portion;
- a first leg formed integrally and extending downwardly from said base portion and located in said first channel between said first lug and said bearing adapter, said first leg comprising two faces extending from a central connecting face at an angle of less than 180 degrees, said leg enclosing the first leg to prevent all contact between said first lug and said bearing adapter;
- and
- second and third legs extending downwardly from said base portion and disposed one each on either side of said second lug such that the engagement of said second lug with said second and third legs limits movement of the wear plate in a plane parallel to said base portion.
In a pedestal side frame of the type having a downwardly facing jaw including a roof portion and opposed sidewall portions extending downwardly from said roof portion, a first lug located on one of said sidewall portions, a second lug located on the other of said sidewall portions opposite the first lug, a bearing adapter adapted to be received in said jaw including a first substantially C-shaped channel for receiving the first lug and a second substantially C-shaped channel for receiving the second lug to thereby retain the bearing adapter in the jaw, and a wear plate disposed between said jaw and said bearing adapter comprising:
- a base portion abutting said roof portion;
- a first leg formed integrally and extending downwardly from said base portion having a substantially C-shaped cross-section as taken in a plane parallel to said base portion dimensioned to be received within said first channel and to receive said first lug, said first leg being located in said first channel between said bearing adapter and said first lug to prevent all contact between said first lug and said contact between said first lug and said adapter;
- and
- second and third legs extending downwardly from said base portion and disposed one each on either side of said second lug such that the engagement of said second lug with said second and third legs limits movement of the wear plate in a plane parallel to said base portion.
In a pedestal side frame of the type having a downwardly facing jaw including a roof portion and opposed sidewall portions extending downwardly from said roof portion, a first lug located on one of said sidewall portions, a second lug located on the other of said sidewall portions opposite the first lug, a bearing adapter adapted to be received in said jaw including a first vertically extending channel for receiving said first lug and a second vertically extending channel for receiving said second lug to retain the bearing adapter in the jaw, and a wear plate disposed between the jaw and the bearing adapter, comprising:
- a base portion abutting said roof portion;
- a first leg formed integrally and extending downwardly from said base portion and located in said first channel between said first lug and said bearing adapter, said first leg comprising two faces extending from a central connecting face a an angle of less than 180 degrees, said leg surrounding the first lug to prevent all contact between said first lug and said bearing adapter;
- and
- a second leg formed integrally and extending downwardly from said base portion and located in said second channel between said second lug and said bearing adapter, said second leg comprising two faces extending from a central connecting face a an angle of less than 180 degrees, said leg surrounding said second lug to prevent all contact between said second lug and said bearing adapter.
