Railway coupler wear member

Claim 2

In a wear member for a railway vehicle wherein said vehicle comprises a pair of relatively movable components and said wear member is supported by one of said components and protects said components from wear during relative movement thereof, the improvement wherein said wear member comprises, a main body made primarily of a polymeric material and having an antifriction wear surface engageable by said other component, support means for said main body, said support means having opposed surface portions, a plurality of openings extending completely through said support means, said polymeric main body having integral parts thereof disposed in embracing relation around said opposed surface portions and completely concealing said openings, and a plurality of rivet-like portions of said polymeric main body corresponding in number and configuration to said plurality of openings, said rivet-like portions extending between the embracing parts as an integral part thereof and through said plurality of openings to hold said main body to said support means.

Claim 3

A wear member as set forth in claim 1 in which said support means comprises at least one L-shaped member having a pair of legs, said plurality of openings being provided in at least one leg thereof, and said opposed surface portions being provided along an outer portion of said one leg.

Claim 4

A wear member as set forth in claim 1 in which said support means comprises a pair of L-shaped members disposed in parallel relation on opposite sides of said main body, each L-shaped member having a pair of legs disposed substantially perpendicular to each other, said plurality of openings being provided in at least one of said legs of each L-shaped member, said opposed surface portions being provided along an outer portion of each of said legs, said polymeric main body having associated parts thereof disposed in embracing relation around opposed surface portions of each of said legs and completely concealing the associated openings therein, and said plurality of rivet-like portions comprising integral rivet-like portions extending between embracing parts associated with each of said one legs of each L-shaped member and through associated openings in each of said one legs.

Claim 5

A wear member as set forth in claim 3 in which the other of said legs of each L-shaped member also has a plurality of openings therein.

Claim 6

A wear member as set forth in claim 3 in which said openings in each of said one legs are elongate openings of substantially equal size disposed in two sets, one of said sets being defined by alternating openings having their elongate dimensions disposed along a common axis, and the other of said sets being defined by alternating openings having their elongate dimensions disposed in spaced parallel relation.

Claim 7

A wear member as set forth in claim 3 in which said polymeric material comprises ultra high molecular weight polyethylene.

Claim 8

A wear member as set forth in claim 6 in which said polyethylene has a molecular weight of at least two million.

Claim 9

A wear member as set forth in claim 6 in which said polyethylene has a molecular weight within the range of four to six million.

Claim 10

In a coupler carrier wear member for a railway vehicle wherein said vehicle comprises a coupler assembly and a coupler carrier which are relatively movable and said coupler carrier wear member is carried by said coupler carrier and protects said coupler assembly and coupler carrier from wear during relative movement thereof, the improvement wherein said wear member comprises, a main body made primarily of a polymeric material and having an antifriction wear surface engageable by said coupler assembly, a pair of spaced supports for said main body with each support having opposed parallel surface portions, a plurality of openings in each support with each opening extending completely through its associated opposed parallel surface portions, said polymeric main body having integral parts thereof disposed in embracing relation around each of said associated opposed surface portions and completely concealing associated openings therethrough, a plurality of rivet-like portions of said polymeric main body corresponding in number and configuration to said plurality of openings, each of said rivet-like portions extending between associated embracing parts as an integral part thereof and through an associated opening, said rivet-like portions holding said main body to said spaced supports.

Claim 11

In a coupler carrier wear member for a railway vehicle wherein said vehicle comprises a coupler assembly and a coupler carrier which are relatively movable and said coupler carrier wear member is carried by said coupler carrier and protects said coupler assembly and coupler carrier from wear during relative movement thereof, the improvement wherein said wear member comprises, a main body made primarily of a polymeric material and having an antifriction wear surface engageable by said coupler assembly, a pair of spaced supports for said main body with each support having opposed parallel surface portions, a plurality of openings in each support with each opening extending completely through its associated opposed parallel surface portions, said polymeric main body having integral parts thereof disposed in embracing relation around each of said associated opposed surface portions and completely concealing associated openings therethrough, a plurality of rivet-like portions of said polymeric main body corresponding in number and configuration to said plurality of openings, each of said rivet-like portions extending between associated embracing parts as an integral part thereof and through an associated opening, said rivet-like portions holding said main body to said spaced supports.

Claim 12

A wear member as set forth in claim 9 in which each of said supports is a metal support member.

Claim 13

A wear member as set forth in claim 9 in which each of said supports is an L-shaped member having a pair of legs disposed substantially perpendicular to each other, said plurality of openings being provided in at least one of said legs of each L-shaped member, and said opposed surface portions being provided along an outer portion of each of said one legs.

Claim 14

A wear member as set forth in claim 11 in which said openings in each of said one legs are elongate openings of substantially equal size defined in cross section by a pair of rectilinear sides and semicircular ends each opening defining a rivet-like portion of substantial length.

Claim 15

A wear member as set forth in claim 12 in which said parts of said main body in embracing relation are of roughly rectangular outline.

Claim 16

A wear member as set forth in claim 13 in which said polymeric material comprises ultra high molecular weight polyethylene having a molecular weight within the range of four to six million.
