Abstract
Abstract A pedestal assembly for use in a railroad vehicle having a journal box which slides vertically with respect to the pedestal assembly, said assembly including a pedestal liner consisting of elastomer having a wear face and a non-wear face, said wear face confronting the journal box, a pedestal liner insert consisting of an elastomer having a first and second side, the first side confronting the non-wear face of the pedestal liner and the second side confronting the pedestal leg, a plurality of spacing washers and a means attaching said pedestal liner and pedestal liner insert to said pedestal leg through said spacing washers and a process for producing the pedestal liner and the pedestal liner insert by injection molding.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
184 words
A pedestal assembly for use in a railroad vehicle having a journal box which slides vertically between spaced-apart pedestal legs, said assembly comprising a channel-shaped elastomer structure having an outer wear face oriented to contact a journal box of a railroad truck when said assembly is mounted on a pedestal leg and an inner face enclosed by parallel upstanding flanges of said channel-shaped structure, said upstanding flanges having a plurality of apertures located remotely to said outer wear face, and a plurality of substantially rigid spacing washers, one of said spacing washers received in each aperture, each of said spacing washers having a cylindrical body connected to an annular flange, allowing its cylindrical body to be received in its associated aperture in one of said upstanding flanges so that the annular flange abuts on the outer surface of said upstanding flange so said washer is operable to limit the compression of said elastomer structure due to the length of said cylindrical body member which forms a stop to limit such compression when a mounting bolt forces said spacing washer inwardly against a pedestal leg.
Claim 2
Dependent Claim
184 words
A pedestal assembly for use in a railroad vehicle having a journal box which slides vertically between spaced-apart pedestal legs, said assembly comprising a channel-shaped elastomer structure having an outer wear face oriented to contact a journal box of a railroad truck when said assembly is mounted on a pedestal leg and an inner face enclosed by parallel upstanding flanges of said channel-shaped structure, said upstanding flanges having a plurality of apertures located remotely to said outer wear face, and a plurality of substantially rigid spacing washers, one of said spacing washers received in each aperture, each of said spacing washers having a cylindrical body connected to an annular flange, allowing its cylindrical body to be received in its associated aperture in one of said upstanding flanges so that the annular flange abuts on the outer surface of said upstanding flange so said washer is operable to limit the compression of said elastomer structure due to the length of said cylindrical body member which forms a stop to limit such compression when a mounting bolt forces said spacing washer inwardly against a pedestal leg.
Claim 3
Dependent Claim
12 words
The pedestal assembly defined in claim 1 wherein the elastomer is nylon.
Claim 4
Dependent Claim
29 words
The pedestal assembly defined in claim 1 wherein the length of the cylindrical body member of each spacing washer is slightly less than the thickness of the associated flange.
Claim 5
Dependent Claim
26 words
The pedestal assembly defined in claim 1 wherein said assembly includes a planar rectangular liner element fixedly secured against the inner face of said channel-shaped structure.
Claim 6
Dependent Claim
15 words
The pedestal assembly defined in claim 4 wherein the liner element is composed of nylon.
